Summer time!
|
Topic: general | Link here |
It has been a really warm November—I'm waiting to see if it was the warmest on record (again)—but now it's summer, so everything has changed. The Bureau of Meteorology has issued dire warnings about rain (up to 300 mm in the next three days!) and flooding. But it didn't quite happen like that. In total we got about 20 mm, still a lot for the beginning of summer, and for the first time in weeks we had to turn the heating on.

Investigating focus distances
|
Topic: photography | Link here |
Spent a lot of time thinking about how to process the information that I have from the Focus stacking measurements that I did on Wednesday. The first thing would be to test my hypothesis that the focus step count is linear proportional to v, the distance from lens to sensor in the thin lens formula. Then I could calculate v (trivially) and u from the formula, and compare it with the results recorded (imprecisely) in Exif tag 0x301.
But what is the value in tag 0x301? I've established that at minimum focus the M.Zuiko Digital ED 60 mm f/2.8 Macro reports a distance of 0.185 m (to the nearest 5 mm). That's less than then 4f minimum distance (0.24 m) from the lens formula. The M.Zuiko Digital ED 30 mm f/3.5 Macro lens reports 0.095 m at minimum focus (at which, however, u < v, since the magnification is 1.25:1). But that, too, is less than the 0.12 m minimum that the formula gives.
So: where is it? From the front of the lens? From the optical centre, wherever that might be? There's only one thing for it: measure it. Here's what I got:
|
|||||||||||||||||||||||
The first is the minimum distance for the 60 mm, the second for the 30 mm. The camera is mounted on the rail at 11 cm from the middle:
|
|||||||||||||||||||||||
But the tripod mount is 1.0 cm ahead of the focal plane, so it's 12.0 cm from the middle of the rail. The 60 mm focuses 6 cm on the other side, or 18.0 cm from the focal plane. The 30 mm focuses almost on its own front element at 2.3 cm from the middle, or 9.7 cm from the focal plane. That fits very well with the Exif data:
| Lens | Position | From front | Total | Exif | ||||
| (mm) | of lens (mm) | (mm) | report | |||||
| 60 | +60 | 75 | 180 | 185 | ||||
| 30 | -23 | 5 | 97 | 95 |
So, we have:
That doesn't make things easier. If the lenses deviate so much from the lens formula, it's difficult to make tenable assumptions about them. More thought needed.

The Dereel Facebook community lit up today: the second radiation tower (Telstra mobile phones) is active. We now have coverage, though some people have reported that things aren't significantly better. I don't see us using our mobile phones significantly more—it's much more expensive than VoIP—but it would certainly be useful if the National Broadband Network fails Yet Again

The vultrs are coming
|
Topic: technology | Link here |
While writing yesterday's diary entries, checked the Vultr web site, not made easier by the fact that they give me a different view of the world if I log in: my current machines (none, of course). But somewhere down the bottom of the page I found a Deploy link. OK, give me a machine in Frankfurt am Main. Can do! And indeed I set up a machine running FreeBSD 11 with surprisingly little difficulty or documentation. How do you set up a completely new remote machine? I was given ssh access Something like:
Setting up squid was something that I had dreaded, but in fact it was relatively easy. The configuration files have got a lot simpler in the course of time. About the only issue was that I ended up with Emacs with its half-coloured syntax highlighting (set the foreground colour, but not the background colour):
|
|
|||||||||
Somehow I managed to remember that I can turn that off with font-lock-mode.
And that was about all. At the end I had:
=== grog@ffm (/dev/pts/2) ~ 3 -> uptime
All in all, a remarkably painless experience. How about a second one? That's more difficult: now that I have a machine, the Deploy link is gone, and I can't find a way to get to the “deploy server” page.

More work in Frankfurt/Main
|
Topic: technology | Link here |
Yesterday's installation of ffm.lemis.com, my virtual machine in Frankfurt am Main went very smoothly. It does what I want it to, but I'm sure it could do more. The obvious first thing to do is to bring the system up to date. Checking out the source tree was nice and fast, but the build itself took forever. There's only one “CPU”, which claims of itself:
That's significantly different from www, which claims:
The buildworld and kernel targets took over 6 hours to run:
I don't know when I last saw anything that slow. But of course, having to build clang every time increases the build time significantly.
One strangeness about the installation is that the system has no swap at all. It only has one partition on the “disk”, which makes it difficult to change anything.
=== root@ffm (/dev/pts/1) /usr/src 8 -> gpart show
Something that the vultures should think about.

Miserable weather
|
Topic: Stones Road house, general | Link here |
Since the beginning of summer, the outside temperatures have ranged from 10.9° to 21.6°. In the last two weeks of spring, they were 11.0° to 35.2°, with daily highs over 30° for all but 4 of those days. We had the air conditioner on cooling throughout that time. Now we're heating, and things look really dreary:

That's at least in part thanks to JG King for not installing the promised double glazing in those windows.

No hot water!
|
Topic: Stones Road house, general | Link here |
Up this morning and discovered that we had no hot water. That's not the first time. And once again it was the internal circuit breaker that I had discovered on 30 March 2016. Now that I know it, it was easy enough to fix. But this is completely unacceptable. In the 2½ years since we've been here, this hot water installation has caused us more problems than all the others I have ever had put together:
High time to get something done about it.

More video download alternatives
|
Topic: multimedia, technology | Link here |
I've been using MediathekView for some months now, and parts of it are excellent. But there are a number of issues:
Is MediathekView really the only choice? Off looking round the web again. I have already established that rtmpdump can download this stuff, but first I need a URL, and there's little information about how to find that on the web.
What I did find was bug reports. And from them I was led to youtube-dl. How about that, it can dissect a web page, find the media and download it. I had discovered part of this a couple of months ago, but I didn't realize how easy it was. Basically you just feed the URL of any page that offers to display a video, at least on the sites that I've seen, and it downloads and stores it. The only issue I have so far is that it doesn't appear to download subtitles. That proves to be a separate option.

Acacia heterophylla?

Topic: gardening | Link here |
While walking the dogs, saw a number of these saplings:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Yes, both of those leaves are growing on the same plant. In fact, there is only one kind of leaf, the fronded (“pinnate”) ones; the others are phyllodes, and clearly the plant is an acacia (wattle). Most adult acacias have no leaves at all, only phyllodes, but this one has both. I came up with the idea of calling them Acacia heterophylla, but of course that name has been taken, for a plant that only grows on Réunion.
Still, it seems that Acacia heterophylla is related to Acacia melanoxylon (blackwood), which grows round here. And then I discover that Acacia melanoxylon has phyllodes, and not leaves, as I had thought. In fact, it looks as if these saplings are Acacia melanoxylon. So is the one with the thousands of pods that I took a couple of days ago. And on looking more closely, this plant also has a combination of pinnate leaves and phyllodes:

All well and good, but we have lots of trees round here with only pinnate leaves which I had taken to be Acacia melanoxylon. What are they?

Trump: Britain First
|
Topic: politics, opinion | Link here |
Donald Trump has not been in office a year yet, but he seems to have nearly the whole world against him. And he appears to be trying to increase the number, after retweeting videos from a British hate group. I was quite impressed by the way that Theresa May condemned the action in terms that were only barely diplomatic.
But that's only one view. After following a link that Yvonne sent me, I found this video of an admittedly depleted House of Commons:
What makes Trump do things like this? I almost have the impression that he has had a bet with Vladimir Putin about how far he can go. He shouldn't go far; he should just go.

Conciliation: teleconference
|
Topic: Stones Road house, general | Link here |
Call from Maggie Keenan of Domestic Buildings Dispute Resolution Victoria today. We had been planning a face-to-face meeting in Ballarat on the 11th, but she suggested that we do it as a teleconference on Wednesday.
I'm not very happy about that. For reasons that—she says—appear to be related to her phone headset, I can barely understand her on the phone, and my recent experiences with teleconferences have done nothing to improve my opinion of this method of communication. It will also make it impossible for me to display videos like this one, from August 2015:
I told her this, and she asked for any documentation that I might produce. That's difficult, since it's on the web, and I might not recall myself until the day. But OK, I sent her a list of the URLs of my diary entries between May 2015 and now. A quick examination suggests that it would print to about 200 pages, maybe more.
And later I received a draft agreement form, somewhat premature I thought. One of the clauses is complete confidentiality, so much so that actually mentioning this here might be a breach of the confidentiality. OK, black hole in the middle? Or should I just give up and go to VCAT? Some of the other conditions, like explicit discharge from further claims, including negligence, make me wonder whether I should continue with the conciliation at all.

DBDRV agreement: OK after all?
|
Topic: Stones Road house, general | Link here |
Yesterday's draft agreement from Domestic Buildings Dispute Resolution Victoria gave me much concern, so today I called up John Curwen-Walker and discussed the matter with him.
That was useful. At the end I had:
Although associated with building, John does not represent people in court. He also doesn't know anybody whom he could personally recommend, and in general he doesn't think that the costs would warrant that approach.
It didn't occur to me until later that VCAT doesn't require lawyers, but clearly that would be an alternative.
The clause requiring me to keep confidential the contents of the agreement and anything said or done during conciliation are intended to ensure that such statements are not later used in court, and not to the form of the agreement itself.
The clause “Subject to performance of the terms of this agreement, the parties mutually release and discharge each other from all further claims, demands, suits and costs of whatsoever nature, including in negligence, howsoever arising out of or in connection with the subject matter of the dispute” had worried me because of the reference to negligence. But it seems it only refers to past negligence, not to any further negligence.
This contract clause is clear in its meaning:
Free double glazed windows. Includes Low E glazing to sliding doors.
As I had asserted, it makes clear that the low E glazing is in addition to double glazing.
So it looks as if the teleconference will go ahead.

“Field” monitor, take 2
|
Topic: photography, technology | Link here |
Why doesn't my new “Field” monitor display the viewfinder image? Last week I was only able to display images that I had already taken, though I noticed discrepancies in the “instructions”. So I've been planning to research further, and today I finally got around to it. And how about that, I found this video showing almost exactly what I was looking for, using an Olympus OM-D E-M1 Mark II.
It's a marginally different monitor, and the first quarter of the 13 minute clip is spent raving over the packaging. But finally he shows the camera doing exactly what I want it to do. OK, I can try that, so I connected up my camera, and how about that, it worked! For the first time I can take a photo of my own viewfinder:
|
|||||||||||||||||||||||
What went wrong last time? After much searching, I discovered that I must have used the wrong camera. The only camera I have that works correctly is the E-M1 Mark II. I must have used the Mark I last time, and that really only displays the recorded images. So does the E-PM1. I didn't bother trying the E-PM2, but the results will almost certainly be the same.
OK, I can live with that, though it doesn't say very much for Olympus.
A couple of things to note:
The monitor tested in the clip above, the Bestview S7, doesn't have the problems with audio and power, so potentially it's a better choice, though it's somewhat more expensive. Apart from that there's not much to choose. The presenter in the clip states that it has a higher resolution than the Feelworld, but he's referring to a different Feelworld monitor: both of these are 1920×1080, with input up to 3840×2160.
Now to get back to my analysis of the Exif data. I've looked at this nearly two years ago, and some of that information is still useful, though I forgot to note how I accessed the information. More digging needed. At least I have an incantation for printing out most of the information I need for focus step analysis:
What I need to find now is what focus differential is set, and I'm not sure how to do that.

Fastest camera wireless connection
|
Topic: photography, technology, opinion, Stones Road house | Link here |
I noted my disappointment with the wireless performance of the Olympus OM-D E-M1 four years ago today, as it happens. Is this just Olympus' fault? It seems not. This article presents the fastest ever (“blazing fast”) wireless controller for a camera: 10 Mb/s! At that speed, it would take nearly 20 seconds per image to transfer photos across the network. Clearly more development is needed.

Powerline Ethernet revisited
|
Topic: technology, general, opinion | Link here |
Jamie Fraser has bought some second-hand powerline Ethernet adapters. I've been there before and had very poor results. But was that maybe due to the power wiring in Kleins Road? I still have a couple (why did I keep them?), so I tried it out today, moving a file from eureka to teevee.
The result?
That's 1.7 MB/s, or 13.6 Mb/s, marginally more than half the capacity of my external Internet link, and about 2.7% of the claimed speed of 500 Mb/s. At least I have confirmed my opinion that they're useless unless connectivity is the most important factor.

DBDRV conciliation teleconference
|
Topic: Stones Road house, general, opinion | Link here |
As planned, we had the Domestic Buildings Dispute Resolution Victoria conciliation talk this afternoon. It took most of the afternoon, and it was like pulling teeth.
My concerns about the nature of the conference were confirmed: I could understand Maggie (the mediator) alright, but I had difficulty understanding Evan Dower from JG King, presumably because of technical limitations. Probably the biggest recognition is that the DBDRV is not the correct authority for my dispute. In every case, it seems that neither Evan nor Maggie (the mediator) understood the issues:
If you live in states that have colder and longer winters, you will need windows with glass that offer greater insulation from the cold than ordinary glass does, such as Low E glass, double glazing or a combination of both.
So what do I do now? I'll gather more evidence, DBDRV will send an assessor, and we'll have another meeting in a month's time. I no longer have much hope that we will reach an agreement.

Investigating new cooktops
|
Topic: general, food and drink | Link here |
One of the questions arising from the DBDRV teleconference was what I would replace the cooktop with. Good question. Currently I'm thinking of a 60 cm gas cooktop and a 30 cm induction cooktop, mounted 30 cm apart so that I can put things like friteuses in between. What requirements do I have?
As I've seen in the past, it's almost impossible to find out this information. So far I've been able to establish the induction power steps for only one cooker. And that was because Appliances Online used to offer the manuals online. They no longer do that—no need to confuse the customer—so I'm even worse off than before. The Baumatic BSIH32 30 Induction Cooktop looks good, but as the lack of a URL shows, the manufacturer doesn't seem to want to know about it. I've seen this so often before, from various manufacturers, that I wonder if it's deliberate.

MediathekView bugs
|
Topic: technology, multimedia | Link here |
As I said a few days ago, I've been using MediathekView for some months now, and parts of it are excellent. But in the last day or two it stopped listing „Abo“ (short for „Abonnement“, subscription) programmes. I've been wondering why, and today I spent quite a bit of time reinstalling and comparing configuration files. It's interesting to look at what the ~/.mediathekview3 directory looks like after it has been running for a while:
=== grog@eureka (/dev/pts/47) ~/.mediathek3 5 -> l
mediadb.txt is effectively empty (3 \n characters). downloadAbos.txt and history.txt appear to be a list of downloads I have performed. It's not obvious what the difference is between the two. downloadAbos.txt looks like this:
I'm not sure what good they are: I can't find a way to display them, unless it's for downloaded files on the Download tab. But when I try that, most of the programmes don't appear.
The two important files are filme.json, a list of film descriptions and URLs, and mediathek.xml, which contains configuration information, including “subscriptions”. Why are there so many old versions? One hypothesis would be that the format is fragile, and in case of damage it's a good idea to be able to fall back to a known good value. I tried this today, and how about that, I worked around the damage! mediathek.xml-copy_3 was OK, mediathek.xml-copy_2 wasn't. OK, what's the difference?
=== grog@eureka (/dev/pts/38) ~ 62 -> diff -wu .mediathek3-no-abos/mediathek.xml_copy_[23]
How I love XML! Admittedly, it would be easier if I reformatted it, but in this case it looks like valid data reflecting changes to my recording list. And this?
That's a valid storage path, but it's only one of many. It's not clear what it's doing here in what appears to be the main part of the config file.
Finally, we have:
This part is a list of some of the channels that I'm looking at. In the newer version, it's completely empty. My guess is that this is the real problem, but it's not clear what exactly the purpose is, since only some of the channels are present. And yes, the tag is really <Downlad> and not <Download>. That's half German: Down in English, lad (load) in German.

Peace in the Middle East, Trump style
|
Topic: politics, opinion | Link here |
I've been ranting about the stupidity of Donald Trump for over a year now, and from time to time I have seen glimmers of hope that he might finally understand his position. But today he announced that he would recognize Al Quds as the capital of Israël. Somehow all his previous actions pale by comparison.
Yes, there are extenuating circumstances: the US Congress passed a resolution to this effect, the Jerusalem Embassy Act (to which the current White House information refers as the “Jerusalem Recognition Act”, possibly the bill introduced in 2011 and never passed) over 20 years ago, the and it was up to the US President to review this decision every 6 months and decide whether to approve or postpone it. And so far every president has postponed it. And yes, he didn't use the term “undivided capital”, and he does note that the current inner borders should remain until a peace settlement:
President Trump reaffirms United States support for the status quo at ... Haram al Sharif.
So what's the fuss? Few people, not even the news reporters, look that carefully. I can't think of any more sensitive territorial dispute anywhere in the world. The symbolism of the action is enormous, as both sides agree: the Israeli government is ecstatic, the Palestinians and other Muslims are enraged. The Palestinians called for “three days of rage””, and it'll be interesting to see what happens tomorrow.
For the USA, things are different: they have been unpopular in the Muslim world for decades, and Donald Trump's recent travel ban has helped fuel that unpopularity. Now they appear to be mortal enemies of Islam. They will no longer be considered an honest broker were it to come to peace talks. The Secretary-General of the United Nations has condemned the act as being in violation of UN resolutions, and almost all other heads of state have also responded negatively.
The satirists have had their view of things, of course, like The Beaverton::
JERUSALEM – In response to US President Donald Trump’s recognition of Jerusalem as the Israeli capital, the Palestinian National Authority has announced that it will recognize Texas as a state of Mexico since it was violently annexed by the United States in the 1840s.
The Palestinian consulate in Mexico City will soon be moved to Houston to formally recognize the seized territory as part of Mexico.
What will the results be? If we're unlucky, there will be a third intifada. That doesn't help the USA, and it doesn't help Israel. It also doesn't help the Arabs, of course. Lose-lose situation. But even if it doesn't happen, at the very least, the USA will lose even more respect and influence, not only in the Middle East.
Trump: making America unimportant again.

More Exif investigations
|
Topic: photography, technology | Link here |
I've been pondering on how to analyse the Exif data from my camera for nearly two weeks now. It's not easy. Today I went back to my investigations of March 2016, which were incompletely noted. It seems that the hacks I described there were against /usr/local/lib/perl5/site_perl/Image/ExifTool/Olympus.pm. I still don't understand the format, and clearly some of it is wrong, but even so, they had one advantage: they show which tags exist, along with some representation of them.
OK, how about a shotgun? For all potential tags between 0x300 and 0x3ff, just add a line like:
That completely ignores data types, but it will at least find the tags and give some representation. Tried that with my photos and got something like:
0x328 looks strange, and it's different for each photo. It is also clearly nothing like int16u data format. So I probably need to understand the exiftool source better.
What about the others? Is 0x302 the focus differential? Which of these change at all? One way to find that:
=== grog@teevee (/dev/pts/6) ~/Photos/20171129/orig/JPEG 8 -> exiftool *.JPG > /eureka/home/var/tmp/exiftool-op
=== grog@teevee (/dev/pts/6) ~/Photos/20171129/orig/JPEG 9 -> sort -u /eureka/home/var/tmp/exiftool-op | less
That's all the 3,000 photos. A surprising number were invariant. Here's a complete list of the ones that varied at all:
That's surprisingly little. About the only one of interest appears to be 0x319, though better interpretation of 0x328 is probably also warranted. But so far the main thing I was looking for—focus differential, in this case one of 2, 4 or 8, doesn't appear to be in that list.

Cooking with inadequate implements

Topic: Stones Road house, food and drink | Link here |
Nothing of any great interest for dinner tonight: pork medaillons with steamed beans and hash browns. But while cooking it, I noted that it maxed out not only our abysmal cooktop, but the induction cooker as well:

|||||||||||||||||||||||
From left to right: lardons for the beans, hash browns, beans and medaillons. Yes, there are another two burners on the cooktop, behind the middle and right pots, but they're not usable because they're too close to the ones in use. And the lardons, which really require a small flame, were on the wok burner, because the small flame was in use running the steamer: it's the only one that doesn't heat too much at minimum.

Walking the dogs

Topic: gardening, animals | Link here |
Somehow about the only time I get out of the house lately is when walking the dogs. Today we took the long way round (Progress Road, Rozenstein Road, Bliss Road), about 3.3 km. The weather has been cool and moist since the beginning of summer—so far, this summer has been markedly cooler than the last 3 weeks of spring—and there are still a lot of flowering plants. These (planted) Callistemon seem to be particularly late in the year:

One-state solution?
|
Topic: politics, opinion | Link here |
You don't have to be a genius to see that the prospect of a Palestinian state is a future goal. For 50 years Israel has occupied the remaining territory of Mandatory Palestine, and there's every sign they intend to stay, to judge by the way they're carving the territory up and placing illegal fortified settlements. And then Donald Trump and enacts what many consider to be a death blow to the idea.
And now Saeb Erekat is suggesting a single state incorporating both Israel and the occupied territories. Ha'aretz reports him as saying:
President Trump has delivered a message to the Palestinian people: the two-state solution is over. Now is the time to transform the struggle for one-state with equal rights for everyone living in historic Palestine, from the river to the sea.
Is that possible? Most world leaders think “no”. But if it were, what would the state look like? Israel is theoretically not a Jewish state, but practice is different. And if there were a one-state solution, it couldn't be called Israel. The Muslims would never accept that. Palestine? That's a good name from a historical point of view, but there's no way the Jews would accept that.
In contrast, my uninformed guess is that the laws of Israel are well-founded enough that they wouldn't need much modification. What needs modification—independent of the number of states in the future—is that the Israelis need to treat the Muslims with dignity. Of all countries in the world, they should know what it is like to treat others as Untermenschen.
In the process, it's interesting to note that even Israeli newspapers are not completely happy with Trump's move. Ha'aretz writes:
Neither Clinton or Rabin, then fully invested in the Oslo Accords, were interested in allowing the nuclear issue of Jerusalem to intrude on the negotiations with the Palestinians at that stage.
It was an attempt by the leader of the opposition, Benjamin Netanyahu, and his allies in Washington to derail Oslo.

Field monitor investigations, continued
|

Chris Bahlo over this afternoon with her Olympus OM-D E-M10 Mark II. I have been interested in whether it would support the Feelworld FW760 “field monitor”. So far only one of my four cameras does; the others switch automatically to playback.
Yes, the E-M10 Mark II also supports the monitor. Like the E-M1 Mark II (and unlike the E-M1 Mark I), it doesn't have an auxiliary viewfinder jack. Maybe a good starting point would be to hypothesize that the two are mutually exclusive.
A surprise with Chris' camera (which she doesn't seem to use much): it had forgotten the date. Why? Did she leave the battery out of the camera too long, or is there something wrong with it, like there is with my Olympus E-PM1? There's nothing in the manual to suggest that leaving the battery out for any length of time should be an issue. But then, it also doesn't describe the error display that indicates that the date is not set.

Vintage wine
|
Topic: food and drink, opinion | Link here |
I've had a bottle of 2003 California (aren't they all?) White Zinfandel in the fridge forever. Why? It's not a wine that I drink, and there's every reason to believe that it has spent the last 10 years in the fridge.
OK, today was the day to do something about it. After all, 12 years ago Kirk McKusick produced one that tasted very good indeed. So we had hope.
And that was all. The wine was definitely not bad in the sense that it had gone off. But it had no bouquet, and it was far too sweet—something that Kirk's wasn't. We came to the conclusion that we could fake one with a weak fruit cordial and a liberal quantity of vodka. We drank something else (a New Zealand Sauvignon blanc).
And Kirk's wine? I recall it as being rosé, but he also called it Zinfandel and not White Zinfandel. Maybe it was the real thing and not this sugary mess.
In 2022, this is puzzling. I had a clear recollection of Kirk telling me that White Zinfandel is something akin to Beaujolais nouveau, and that it is not properly fermented. That exactly matches today's experience.

Music while you ride
|
Topic: multimedia | Link here |
Over to Chris Bahlo's place for the first time in a while: she has put an old amplifier in her riding hall for music while she's riding (or maybe just as a background for videos), but it makes almost no sound at all. Took over my Sony Mini-HiFi system that I bought nearly 9 years ago to compare, and discovered that her amplifier and my system have one thing in common: the volume control doesn't know which way it is turning. But we got reasonable sound out of the loudspeakers, though not deafening. Is there something wrong with the loudspeakers? I got them free some years back, and never used them much before giving them to Chris
But the difference in volume suggests that there's something wrong with the amplifier too. Apart from the lack of volume, there's considerable hum to be heard in the speakers. So possibly it's on its last legs. Chris brought out a computer loudspeaker system which proved the point by being louder than either setup.

Focus stacking with field monitor
|
Topic: photography | Link here |
For the first time, I took my focus stacked photos with the field monitor attached to the Olympus OM-D E-M1 Mark II:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Things weren't quite what I expected. I had the camera set to take 20 images, but when I pressed the shutter, it took exactly one. Did I have something set wrong in the menus? Took a look and found:
|
|||||||||||||||||||||||
Why are those top items greyed out? I discovered that if I pull the HDMI jack from the monitor, it will work, so the simple answer is “because the monitor is connected”. But why? Why should the monitor stop focus stacking? What a kludge!
There are others, too:
|
|||||||||||||||||||||||
In this one, “Connection to Smartphone” is greyed out under normal circumstances as well. Presumably it wants you to climb somewhere else in the menu to establish a connection. But why disable “Print Order” and “Copy All”?
|
|||||||||||||||||||||||
I had no idea what this strange greyed-out symbol is, but it appears to be monitor brightness adjustment. I suppose that one makes sense.
|
|||||||||||||||||||||||
“Frame rate” is something that, it seems, the manual writers don't understand either. They write:
If set to [High], a moving subject can be tracked more smoothly. However, the number of frames to be shot will decrease slightly.
This setting is automatically set to [Standard] if the camera becomes hot.
What does that mean? But potentially it's related to the monitor. The second statement suggests that it's a power consumption issue. Why should it be disabled for an external monitor? Maybe because of the video frame rate?
|
|||||||||||||||||||||||
OK, this refers to viewfinder settings, so there's some justification for greying them out. But in principle some of them would make sense on the external monitor as well.
|
|||||||||||||||||||||||
Since I don't have Eye-Fi (who does?), that menu item is always greyed out. But why are the others disabled with an external monitor is connected?
All in all, I suspect that at least a part of this is a bug. But before reporting to Olympus, I need to investigate further.

Buying Zerene
|
Topic: technology, photography, opinion | Link here |
My experiments with focus stacking software last month made it clear that I should buy Zerene and not Helicon Focus. And today I needed to do so: my 30 days free trial were up. So off to the Zerene web site, where they asked me for $89, as advertised—and $8.90 GST!
Why that? Imported stuff under $1,000 is (still) free of tax. Sent an email asking why, and half an hour later got an answer from the author, Rik Littlefield, explaining the situation, after having checked the ATO web site. He didn't find the $1,000 limit (that's here), but did note that it didn't apply to companies with a turnover less than $75,000 per annum, so he issued an invoice without tax, and with a 10% Christmas rebate that hadn't made it to the web site. So instead of $97.90, I only had to pay $81,10. You can't complain about that, especially when you consider that this all happened somewhere before Saturday midnight his time.

More field monitor investigations
|
Topic: photography | Link here |
Chris Bahlo over again today, bringing her camera (Olympus OM-D E-M10 Mark II) with her. Connected it to my Feelworld FW760 “field monitor”, and, sure enough, it displayed the same behaviour as my Olympus OM-D E-M1 Mark II did yesterday. I'm still puzzled why, but it makes it more difficult to dismiss as a bug. And a post to the Facebook Olympus macro group went without answer, suggesting that I'm doing something unusual in using the monitor with focus stacking.
In passing, it's interesting to note that the E-M10 Mark II does have focus stacking, just not the in-camera variety. That makes it an even more interesting camera.

Zerene stacker on FreeBSD
|
Topic: photography, technology | Link here |
I have already established that Zerene will install on FreeBSD. But will it run? In principle if a program that runs on Linux installs on FreeBSD, it will run too. So I tried it out, in the process tripping over a few nits. Yes, it runs, loads files, displays them. But then I got an unexpected surprise while trying to stack them:

That's more than just an adaptation issue. Something to do with locking? It could be complicated. A good thing I don't have to rely on the functionality.

A new TV
|
Topic: multimedia, technology | Link here |
My TV has been giving me problems: from time to time, when I turn it on, it runs for a minute or so and then hangs hard, requiring a physical power off to continue. But today, even that didn't help, and to watch the news in the afternoon I put a normal computer monitor in its place.
What do I do now? I bought this TV 4½ years ago, my first ever digital TV. And like the three projectors before it, I really only need it as a monitor: the interface to real TVs was just too fiddly. It has a 58" 1920x1080 (“Full HD”) display, and I was estimating that it would last 4 years, by which time 3840x2160 (“UHD”) would be the norm. So it more or less fulfilled my expectations.
So what do I do now? ALDI had a 65" 3840x2160 model on offer 3 months ago, and there's a very good chance that a new one will be along soon. But what do we do in the meantime? Yvonne made it clear that she didn't want to use a 22" monitor for any length of time. And maybe more mainstream TVs would be more reliable.
Off to Staticice to see what was on offer. After the normal cheap accessories, found this one:
$438.73 45-304-026 Ergotron Interactive Arm Vhd For TV 30 - 60" 15KG - 31KG Polishe...
But that's just an arm! The real TVs started with:
$995.00 60P20US TCL 60"(152cm) UHD LED LCD Smart TV
That's $200 more than the ALDI 65" model. But it's a smart TV, which might be worth something, and it's available in stock at The Good Guys in Ballarat. Further investigation showed that there are really only two relatively cheap models available: this one, and a Hisense 65N7 for $1,295 (“recommended retail price $3499”). That was in stock at the Good Guys too, but it has a proprietary operating system, while the TCL uses Android. And yes, just about all TVs now are 3840x2160.
Off to Ballarat to take a look, and in the end decided for the TCL exactly for that reason. While there, picked up a plank to put it on. The old TV had a traditional middle stand, which fitted on top of the cabinet:
|
|||||||||||||||||||||||
But the newer TVs have two stands, one at each end, and in this case wider than the cabinet, something that I hadn't anticipated when I ordered it. So for the time being the TV is mounted on the plank:
|
|||||||||||||||||||||||
I suppose the ultimate solution will be to mount it on the wall.
Arrived back home at 17:50 or so. How long does it take to install a TV? First we had to move the old TV out of the way. Then unpack the TV. How do you lift it out of the package? The instructions were as unhelpful as ever, but then I discovered that after removing the tapes, the bottom just fell out. And this TV is so much lighter that I was able to lift it into place by myself.
Plug in. Initially just power and HDMI cable. One of these days I'll set up TV reception, but for the time being it's just a glorified monitor.
The power cable was the first issue. The power points are to the left of the TV, and the power cable is connected on the right. And it's approximately the width of the TV. Clever thinking there. Still, within 30 minutes of getting home, I had it ready for setup:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
OK, why not? How did it connect? Via Bluetooth? The phone display suggested that it was using a WLAN connection:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
But that normally requires authentication, and it didn't ask for any. Possibly it tried first and found it didn't need to ask for it.
OK, what now?
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Copy all my phone data to the TV? My GPS apps? OI.Share? Of course not! And my accounts? What kind of security is that? OK, say no.
But I can't. It doesn't give me a choice. So I stopped the app, getting a typically precise error message:
|
|||||||||||||||||||||||
Continuing wasn't much more help. I was still given a Mafia-style choice:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Dammit, I want a TV, not a contract signing away my rights! In the end I had to accept the second one just to continue, but I'm not happy. I'd see that as a valid reason to return the item.
Next, I had to give the machine a name. It suggested TV. OK, that makes sense. Let's keep it. Ah, no, that was just a suggestion. You have to enter a name with a toy simulated keyboard, and tell the device where it is located.
|
|||||||||||||||||||||||
Finally negotiated that, and then it wanted to “install” channels. I don't have an antenna cable connected, and for tonight I just wanted to watch pre-recorded programmes. Skip? First I need to get there; somehow the screen navigation was just plain bizarre, and first I had to go through the “Type” field. Then “Skip” and... back to naming the bloody machine with the toy keyboard!
|
|||||||||||||||||||||||
Somehow I managed it. It seemed to take forever, but in fact it was only 12 minutes. That's still a lot compared to 30 for the physical actions of removing old TV, and unpacking, positioning and cabling the new one.
Next, connect teevee to it. Total failure! Looking at /var/log/Xorg.0.log, I saw:
Nothing connected? How can that be? Dragged out a second HDMI cable and connected it to the old 22" monitor. No problem. Disconnected the cable from the monitor and plugged it in to the TV (HDMI 2 input). Works, at 1920x1080. OK, that's enough for today.
Watched TV, in the process noting a considerable difference in colour. The greens look much better, and the yellows look really bad. But there are all sorts of things that I can tweak.
Just before going to bed, started X again to see if I could get some response from the TV. This time it was found:
That raises a number of questions: why didn't it work before? Cable problem? Input jack dependency? And why is it only running at 1920×1080? Because of my X config? All stuff for another day.
In the interim, it's worth noting some things:
I've continually slammed Android because of the horrible user interface. Touch screen keyboards are the worst thing I can think of—I thought. I had forgotten the kind of keyboard that the TV made me use. I wonder if I can connect a Bluetooth keyboard. Or could I even install real software on the thing and access it via ssh?
The wording in the messages is appallingly bad. Clearly nobody checks the grammar and spelling. Just in the images I captured during installation, I have:
Terms of conditions
Choose Agree, and you will enjoy more priviledges.
Next step is to represent you have read and agreed.
Channel installation
You don't install channels, you locate them
It's easier to find your TV, when you use T-Cast or bluetooth functions.
Apart from the capitalization, that comma screams “German!”. In German, a comma is obligatory at this point, whereas in English it changes the meaning. It's not clear what they meant here.
You do not perform any operation
Not only is this message strangely formulated, but it's incorrect. I was desperately trying to communicate with the bloody thing.

Why Android TV?
|
Topic: multimedia, opinion | Link here |
In the end, I'm left wondering whether I made the right choice with an Android TV. Do I really need it? It makes Android phones look good. Of course, there are many things that could really be useful. First, let's consider what they offer:
HDR Pro.
I need to investigate what this means. But it doesn't seem to have anything to do with Android: it seems that some form of HDR is standard on modern TVs.
Netflix/Stan. Potentially this is a good idea, though I dislike the approach of Netflix, and I hadn't heard of Stan until today.
DTS Sound, another thing I hadn't heard of before today. It's multichannel, so potentially uninteresting in our environment.
3 year warranty. A good idea. I could have increased it to 5 years for another $170 odd. That would have saved me from buying a new TV today, but it's not clear that it's worth that much. After all, technology has moved on.
Now, what would I like? The TV contains a computer. Theoretically it could replace teevee, the computer that I use to drive the TV display. Can it in practice? I fear not. Firstly it would need a keyboard and mouse, and the ability to run real programs and not apps. Can I set up NFS on it? Then I could access files directly on another computer—if I can get software to display from a file, either the supplied software or some app. And running a web browser is becoming more and more complicated nowadays without having to submit to deliberately castrated platforms. In particular the requirement to accept license conditions annoys me greatly.

My own devices
|
Topic: language | Link here |
In passing, I think I am developing an aversion to overuse of the term “device”, though I use it above. Current technology seems to be stretching an already well-worn word. The OED has no less than 12 main meanings, not including this current meaning, but including
3. a. Will, pleasure, inclination, fancy, desire. In earlier use chiefly in phr. at one's (own) device; later only in pl.; now only in phr. left to one's own devices, etc., where it is associated with sense 6.
6. Something devised or contrived for bringing about some end or result; an arrangement, plan, scheme, project, contrivance; an ingenious or clever expedient; often one of an underhand or evil character; a plot, stratagem, trick.
7. a. concr. The result of contriving; something devised or framed by art or inventive power; an invention, contrivance; esp. a mechanical contrivance (usually of a simple character) for some particular purpose.
c. Orig., a detonating mechanism for an explosive; in extended use, any explosive or incendiary apparatus; spec. a nuclear bomb (in full, and more usually, nuclear device).
In a fictional work: a character, event, narrative technique, etc., used in order to bring about a desired effect or to advance the plot. Frequently with distinguishing word, as literary device, narrative device, plot device, etc.
Apart from the over-use, the term is imprecise. It includes computers, phones, cameras, TVs, watches and presumably other things as well. Is it really necessary to use it when a more specific term would do better?

Bloody power outage!
|
Topic: general, opinion | Link here |
Another power outage today, this time planned by Powercor. At least it meant that I was able to prepare for it, but at 4 hours, 17 minutes I'm left wondering if they really had to make it that long. If they had to reimburse customers anyway, based on the length of the outage, I'm sure they'd find a way to restore power sooner.
|
Bloody connectors!, part 1
|
Topic: technology | Link here |
Took advantage of the power outage to finally install the new 4 TB disk drive in eureka. The good news is that the reboot worked with no trouble. Services that still require manual start are:
Yes, there are probably ways to get them started automatically, but that would require thinking, and there are some non-obvious issues involved, like loading ssh keys.
But when I took a look at the disk, there was something strange:
=== root@eureka (/dev/pts/3) ~ 7 -> gpart show ada3
Huh? Why did it show a freebsd-ufs partition? It took a while to realize that I had found an unused disk in the machine. And comparing the number of disks connected, one was missing. A mount confirmed that yes, indeed, /dev/ada3p1 was a valid FreeBSD file system. So where was the new disk?
Powered down again. Cable problems? The machine already had 5 disk power connectors, and I had to use an existing Y cable for the new disk's power. Could it be that there was something wrong with it? Pulled the power connector from the old ada3, squeezed the disk into position and... destroyed the connector. I didn't realize how flimsy they are. Damn!
So now I have only 4 power connectors, just enough to run the 4 existing disks. I can get a new cable, or find a way to install the disk from another machine. I think I'll take the latter course.

Bloody connectors!, part 2
|
Topic: multimedia | Link here |
Back to looking at the new TV. Started teevee up, and it ran fine on HDMI input 2. Plugged in to HDMI 1. Yes, fine. OK, let's use the correct cable. No go.
That cable worked fine on the old TV. Why not here? Are there some compatibility issues? The new TV uses the latest HDMI spec (which? why should that be in the specs?), and potentially the cable is down-rev. But I wouldn't have expected that to be an issue. Or did I somehow damage it in the installation process? In any case, it looks like a replacement is due the next time that ALDI has them on special.

Next, connect up an antenna cable and scan for channels. First problem was: where do I find the channel scan function? The method in the instruction manual didn't work: the menu item (Channel/Channel scan) was missing. The way I found was to try to select a “channel” with the channel down/up switch (which, irritatingly, moves in the opposite direction from other multimedia equipment I have seen). Then I got the install screen that I had seen yesterday:
|
|||||||||||||||||||||||
Scan everything. Nothing found! Another cable problem? Connected up the radio tuner, and that worked fine. Swap cables? In the process discovered that there was some connection problem with the radio, and I had to wobble the cable to get a good connection.
Much cursing and swearing later, I finally connected the TV almost directly to the antenna socket (via the absolutely necessary amplifier adapter), and I was able to scan. So somewhere, probably with the powered 4-way splitter or one of the stupid adapters needed to connect normal cables, there's a problem. Mañana o pasado mañana.

Configuring new TV
|
Topic: multimedia, technology | Link here |
OK, let's configure the new TV. Where's the configuration menu? There seem to be four different ways to access parts of the configuration. The (grey) “equivalence” key on the right and the star in the middle here give different menus, the program selector on the right will bring up a (different) menu if it can't find any channels, and the “home” key at bottom left adds things like network configuration if you scroll down far enough:

And I can add a static address if I want, and if I can bear the interface (admire the overlapping text):

What use smart TVs?
|
Topic: multimedia, opinion | Link here |
In principle, it makes a lot of sense to have a TV with computer functions. And maybe Android is the right choice. Or is it?
One of the biggest issues with Android and similar systems is that it is designed for mobile telephones and other very small devices. There's no place for a keyboard, and the alternatives are poor at best. In general, I find that Android and iOS vie for the worst ever user interface. On the other hand, I really can't see a general alternative for mobile phones, except for “well don't do that, then”. So I barely use them.
Things are different with a 60" TV. My new TV is the largest display device I have ever owned, and it comes close to having the resolution of all four of my desktop monitors put together. It's clearly not mobile. And compared to a mobile phone, you're normally not in direct contact with it, so even the appalling touch screen keyboard functionality isn't available. Instead there's this monstrosity, which makes even touch screen keyboards look good:
|
|||||||||||||||||||||||
But why? This TV includes a real computer. The specifications say that it's a Quad Core. Quad Core what? Who knows? Who cares? It's Quad Core. And it has all sorts of interfaces: USB, HDMI, Bluetooth, 802.11, Ethernet. So why use this stupid keyboard interface? It can't be the size. A long time ago Chris Bahlo lent me a Bluetooth keyboard that we never got to work. It's not even as long as the remote control:
|
|||||||||||||||||||||||
Will it work with the TV? One of the configuration menus (the one at the bottom of the Home icon) allows pairing Bluetooth devices. Problem: I've never been able to get this device to pair. When I turn the thing on, the LED lights up for a second or two. But then? Nothing.
What's the model number? What's the name? It's on the space key:
|
|
|||||||||
I read ΓΛΡΟΟ, or GLROO in Roman characters. But no, we're in the 21st century now, nobody knows Greek any more. It's really a mutilated RAPOO. And they have engraved the model number in the metal on the back in about 4 point text that you can only read in the right light:
|
|||||||||||||||||||||||
|
|
|||||||||
BT confused me for a while, but it seems that means Bluetooth. The model number is E-6500. OK, let's look for a manual. Nope, no manual, but there's a FAQ, which doesn't mention the E-6500, clearly last year's model. After only a few mouse clicks, I'm at Keyboards/Bluetooth Keyboard, which tells me (or asks me) “How to pair to the bluetooth keyboard?”:
OK, I'm stuck at step 2. Where's the Connect button? Does it have some other name? Why isn't there a picture? I spent 5 minutes trying to second-guess what symbol might represent the Connect button, without success.
If Glroo can't help, how about YouTube?
And how about that, at 2:52 into the clip I find:
|
|||||||||||||||||||||||
The Connect button has been obscured by a conformity label! Now isn't that clever!
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
After that, of course, I was able to pair the keyboard.
|
Smart TV: why?
|
Topic: multimedia, opinion | Link here |
So now I have a smart TV with a Quad Core and and Android operating system and multiple network connections. What can I do with it? Even with a keyboard, the interface is painful to navigate. Where's a web browser? I frequently use one to check on things while watching TV. Maybe I can install one from the toyshop, but the fact that there isn't one by default should serve as a warning. Probably it's a consequence of the appalling user interface. Who wants to browse with a toy toy (no typo) keyboard? I've been using X for nearly 30 years, and even when I started, using computers with only a fraction of the processing power or resolution of this one, the user interface was an order of magnitude better than what I can see.
Still, give it a chance. The Home icon gives me all sorts of icons: Netflix and Stan., both of whom want money from me. One that claims not to is Spotify, which claims to give me millions of songs to match my tastes.
OK, sign up. Even with the Bluetooth keyboard, it's a pain, so I did most of it via the X interface. $0.99 for 3 months? Oh, just joking, there's a free service. So I did that, logged in, got a transient message saying I wasn't registered, and then a list of icons reminiscent of Microsoft “Windows” 10. Finally I found classical music. Classifications? No, just more icons. Finally, for the fun of it, I tried Dvořák 9:
|
|||||||||||||||||||||||
And how about that, I got some of the symphony—the finale only.
Somehow it seems that all these services offer the absolute minimum. What am I missing? This stuff is making fortunes for people, and I still can't find any use for it. Maybe things will change if I can find something useful in Netflix or Stan., but I'm not holding my breath. So far I can't see anything that comes even close to my current environment based on FreeBSD and X.

Two weeks ago I tried to set up a server with Vultr, only to be told that there were none available at my chosen location (Frankfurt/Main). So I put myself on a ”please notify” list. But the following day I discovered that they were available after all, and set up a machine quite rapidly.
But vultrs don't forget, it seems. Today I received an email:
Maybe they now have the el-cheapo $2.50 VMs? No, they're still “sold out”, which sounds to me like they're never really available.

Connecting the TV to the network involved adding a switch in the lounge room:
|
|||||||||||||||||||||||
|
|
|||||||||
That went easily enough, but later I discovered that copying image files from eureka went at a snail's pace. A quick examination with netstat -biIem0 1 confirmed. Here first with the switch connected, then disconnected and teevee connected directly to the wall socket:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
The fourth column is the number of bytes input per second. At first it doesn't look much different, but in fact it's an order of magnitude. With the switch it's round 11.5 MB/s, without it it's round 108 MB/s.
Why? This isn't the only switch in the circuit. There's one in my office and one in the pantry, both more professional units than this one. Is it the number of switches, or the quality of this particular one? I'd guess the latter. In any case, I don't really need the switch. The TV has a WLAN interface as well, and it doesn't seem that there's much use for the connectivity in any case.

Scaredy cat
|
Topic: animals | Link here |
One of the first things I do in the morning when I get up is go to the laundry and let Piccola out: she hears the blinds going up and starts meowing. When I let her out, she heads straight for the front door and goes out for about 15 minutes, after which she returns expecting food.
But not today. She wasn't there. Had Yvonne got there first? Normally I hear her meowing, but not today. Checked. No Yvonne. Back to the laundry and looked behind the washing machine:
|
|||||||||||||||||||||||
What was she doing there? Had she fallen down? I moved the drier (beyond the bottom of that photo) to one side, and she got out, and went out into the house.
To the front door. No Piccola. Gone again. After some searching I found her in a cabinet in the corner of the lounge room. She got out and went behind another cabinet.
What's all that about? We had noticed that she had stayed in the garage all yesterday evening. The garage is one of her favourite places, but normally she comes to us in the lounge room in the evening, and this time she didn't call. She had eaten her food, so it didn't seem likely that she was sick, and she wasn't obviously injured. During the course of the day it became clear that she was afraid of something—very afraid. But what? It wasn't the dogs: she went up to them and rubbed against them as usual. She calmed down by evening, but it still wasn't over.
The Marriotts are looking after a couple of Jack Russell terriers for the while. Did one of them chase her? She'd not injured, but it could have been a close call.

DBDRV assessment
|
Topic: Stones Road house, opinion | Link here |
Llewellyn Pritchard (“LP”) of the DBDRV along today to assess my issues with the house, joined by no less than three people from JG King: Evan Dower, (General Manager), Ashley Barker (Maintenance Manager) and Michael Gibess (Area Manager, spelling as reported by DBDRV). It seems that this was their first experience with DBDRV, which is apparently quite a new institution, thus the large number of attendees. Things didn't go overly well.
I had prepared a printout of the installation manual for the cooktop, and showed LP the diagram showing how to set up the low flame, as two years ago:
|
|
||||||||
No, he didn't say “but that's just a drawing”. He said that it was an artist's impression. So I showed him once again how it was possible to adjust the flame lower by setting the knob between “off” and “full”, something that surprised him—he apparently didn't know this was possible. Here the difference, first “minimum” and then the way it should be:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
I was left with the impression that he had never seen any of this before. He did, however, take detailed notes.
It was similar with the range hood. To test it, he put a sheet of A4 paper against the filter! And only in the middle, where it (barely) works. And like his predecessors, he chose a random piece of paper (in this case part of the cooktop instructions) without considering that the filter might be fatty. No measuring instruments. In fact, he had to ask me how I measured my 110 m³/hr, and I had to spell anemometer for him.
He then asked for a ladder to take a look in the roof to confirm or deny the statement of a previous inspection that there were two bends in the ducting. He didn't get more than his shoulders through the manhole, and he didn't see anything to confirm the two bends. He also didn't shut the manhole when he came down, and I had to do it after he left.
The floors were a different matter. At first he had expected wooden floors because of the pattern drawn on the plans: Evan had to point out to him that the pattern represented the floor covering (which was marked on the plan). I had said that there was a difference of up to 5 mm in the level across the diagonal of a side table we use in the lounge room (64 cm; I had previously said 50 cm, but who cares?). Evan said that the standard (“code”) specified an unevenness of up to 4 mm across 2 m, so my claims weren't important. I asked LP to explain to him that the former was sufficient to show the latter, but he didn't know either, and Evan pointed out that he had once been a surveyor, so he knew what he was talking about... God help us.
LP pulled out a laser level and measured the level at exactly 4 points one and two metres away. And how about that, he found a discrepancy of 5 mm. That has absolutely nothing to do with the issue at hand, but he seems to be satisfied with it. In passing, it's interesting that he measured over a distance of nearly 4 metres, 2 metres in two almost opposite directions, but nobody else seems to have noticed.
In passing, Evan blamed the unevenness of the slab on the “accident” we had had, where Brett Chiltern had damaged the bore water pipes (which he claimed were storm water):
|
|||||||||||||||||||||||
That's nonsense, of course. The amount of water that leaked was less than the rainfall in an average winter, the location was about 10 metres away from where we were measuring, roughly at the corner of the eave overlap at top right of the plan extract below, and it had nothing to do with the house slab.
|
|||||||||||||||||||||||
But I'm quite impressed that he has gone to the trouble to read my diary.
With the windows, LP referred to the plans:
|
|
|||||||||
The window in the lounge room (“family” in the plan) is marked PAW1527.DG, and the door to the verandah is marked SSD2127-3.LOWE. Clearly the DG means “double glazed” and the “LOWE” means “Low E”.
Is that clear? I asked them what the other code meant. Ash knew that the numbers were a code for the dimensions (height, then width in dm?). They decided that W is Window, and by extension D must mean Door. And PA? After a little discussion they decided that A stood for Awning, and about 10 minutes later, after further input, they concluded that P was an abbreviation for the supplier name. Sorry, people, that's not clear even to you. It's certainly not clear to people who only speak English.
While discussing the windows, he told me that Low E would provide 80% of the advantages of double glazing, even in the winter. I explained to him the basics of heat transfer (conduction, convection, radiation), something that he had apparently not heard of, and pointed to the fact that the single-glazed windows steamed up in cold, wet weather, while the double glazed ones did not:
|
|||||||||||||||||||||||
Another point of interest: all were agreed that double glazing would be too heavy for the doors. But then Evan said that they do, indeed, use double glazing in commercial buildings. How can they do that? And why don't they do it in domestic buildings? At the very least, this indicates the weakness of their claims.
So. What's going to happen? We'll see. Certainly LP seemed neutral enough, and he tried hard, but I have the feeling that he hasn't the necessary technical skills to assess the issues. Maybe Evan is correct when he says that this is the first time clients have raised issues like this: they seem to transcend their understanding.

Piccola still afraid
|
Topic: animals | Link here |
Piccola is gradually recovering from her shock, whatever it may have been, but she didn't leave the house all day, and she seems to be afraid to go into the laundry. Why? What could have happened in there?
In any case, it's clear that it will take a while for her to recover. She spent a lot of time in the garage again, and over night we left her in the house with the doors to laundry and garage open.

Garden flowers in early summer
|
Topic: gardening | Link here |
Middle of the month, time for my monthly flower photos. This month I somewhat extended my range by taking photos of many tiny (wild?)flowers that I had previously ignored. That included focus stacking, something that wasn't completely successful.
The Anigozanthos (kangaroo paw) plants are doing very well. This is the one that Sasha chewed on a couple of years ago. It has recovered well:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
And these are the ones that Petra Gietz gave us a year ago:
|
|||||||||||||||||||||||
The Box elder is growing relatively fast, though not enough for Yvonne's liking:
|
|||||||||||||||||||||||
The Buddlejas in the south are doing from well to badly. This one is over a metre tall and is developing flower heads that we expect next month:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
This one is only about 40 cm high, but it's looking a lot better than last month (first photo):
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
That may be due to the liberal dose of fertilizer I gave it. On the other hand, that doesn't seem to have helped this one, which is barely alive:
|
|||||||||||||||||||||||
The Clematis that we paid so much money for last month are still there. And that's all. They don't seem to have grown at all:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
The grass spike that I identified last month has now flowered. First, last month:
|
|||||||||||||||||||||||
This month it seems to be fully open:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
The thing must be about 3 m tall.
The black grass that we brought from Kleins Road, and which never seemed to do very much, is also flowering:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
And the Hebes are also finally flowering relatively consistently:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
I think this is an indication that they need more fertilizer than I have given them in the past.
The Leucospermum cordifolium is now also in full flower, though there are still more heads maturing:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
And the various lilies that we have planted over the last couple of years are all coming up now:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
The Cannas are in full flower:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
The big tree fern is looking presentable again, and the little one appears to be raising a finger at the person who cut off all its shoots:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
The roses are doing OK, but not well, possibly because they haven't been cared for. Time for more regular pruning:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Indoors there's not much to see. The Hibiscus rosa-sinensis are currently hardly flowering at all. This is the best that I could bring up today (15 December), though more are on their way:
|
|||||||||||||||||||||||
The Phalaenopsis are still flowering, though it's clear it won't last much longer now:
|
|||||||||||||||||||||||
And though the Begonias are not overly profuse, they have grown extensively:
|
|||||||||||||||||||||||
Time to trim them.
There are lots of smaller flowers on the property that might be considered weeds, but maybe they're not. Here are some that I've identified:
This one looks something like a Dandelion, but it doesn't develop puffballs. It also grows in water. Somewhere I have seen an indication that it's an Australian native:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
This one is really tiny, with flowers only a couple of millimetres across. It's visible in the first photo (amongst the Carpobrotus) only on careful examination.
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Yvonne thinks, probably with some justification, that this might be a species of Lobelia, and thus exotic:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
This one is growing in the nature strip between the house and the road. It's the first time I've seen it, and it, too, might be exotic:
|
|||||||||||||||||||||||
This is another tiny one, but apparently distinct from the previous. The hose in the background is 19 mm in diameter.
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Here's yet another. The leaves are different. Hopefully I can get a better photo:
|
|||||||||||||||||||||||
Here's yet another that looks similar, but only at first sight. I need better photos:
|
|||||||||||||||||||||||
This one is everywhere this year, even in our old pots:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
And this one I've seen before. Again I need better photos:
|
|||||||||||||||||||||||

More focus stacking fun
|
Topic: photography | Link here |
I took two cameras with me for the garden flower photos: the Olympus OM-D E-M1 Mark I with the M.Zuiko Digital ED 12-100 mm f/4.0 IS PRO for the normal photos, and the OM-D E-M1 Mark II with the M.Zuiko Digital ED 60 mm f/2.8 Macro for closeups, using focus stacking (20 images with a focus differential of 2, taking about 1.5 seconds for the sequence (why?)), and rather incautiously hand-held. In all I took 400 images for 20 photos. Things didn't all work out well, mainly because of the wind. Here an example, on which I hope to improve:

More Android TV pain
|
Topic: multimedia, opinion | Link here |
I really want to understand what advantage, if any, there is in Android TV. Today I had another go, trying to watch something on YouTube that I had been watching on my computer earlier (Kirk McKusick talking about the history of BSD). I failed.
First, of course, I had to log in. I had the Bluetooth keyboard, which now pairs happily, and I was able to log in to Google with that, but I couldn't find a way to enter a text to YouTube. I was only able to choose what it offered me. Yes, it included my “subscriptions”, but I hadn't subscribed to this one. There seems to be no way to configure the thing to accept text.
As I see it, we have gone through the following transition:
The trouble with the TV is that the evolution has taken it out on a limb that makes it almost useless. The voice input didn't work for me At All. No misrecognition, just no evidence that it was even active. But I couldn't find a way to type into what looked like an input field.
Are keyboards “inappropriate” devices for TVs? I visited the Marriotts next door in the afternoon, trying to give away my old TV, but they have just bought a new one themselves. It, too, is “smart”, but since it was only half the price of mine, it comes with a double sided remote control:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Still, even this logical idea has its limits: unless Kogan also has a different implementation of Android TV, it's not much use. And it's so tiny that it's not very useful. Why do you need a tiny keyboard for an enormous TV? Most people use normal sized keyboards for computers, so why not for TVs?
The Marriotts agreed with me: Diane wanted to connect a normal computer keyboard to the device. That would probably work, since the thing has a USB connector, and in fact that's how the remote control talks to the computer. A cable would be a nuisance, but infrared connections, like in my current setup, should work fine. But once it's connected, what can you do with it against such a broken system?

Spotify: another reason not to use us
|
Topic: multimedia, opinion | Link here |
Spam from Spotify today:

Get beats, not breaks? What does that mean? That their “songs” should have rhythm and not be broken? More likely, a commercial break? Do they have them? Reading the small print confirms:
|
|
|||||||||
|
|
|||||||||
I didn't listen to their music long enough to notice that. But look at those prices! That's more than Netflix charges!
I really want to find some advantage in this system. It was introduced about a quarter of a century after I first started using X, and I can find absolutely no advantage in it whatsoever.
Where's the progress? What am I missing?

Understanding foreign cultures

Topic: general, opinion | Link here |
Somebody posted this image on IRC today:
The original image was at https://pbs.twimg.com/media/DQ1nPAzW4AAIEvF.jpg, but it has succumbed to bit rot.
The first impression is that it's tasteless. But is it? It shows a man nailed to a cross, something that is really the symbol of Christianity. Yes, it's the wrong man, and he's clothed. But why should this look tasteless and shocking where Jesus nailed to the cross doesn't? The only real difference is centuries of adaptation to the idea. And in a way, that's a pity: the Christians have a reason to represent the crucifixion as a central symbol of their religion, and it was once supposed to shock.

Saturday dinner

Topic: food and drink, general | Link here |
It was Chris Bahlo's birthday on Thursday, so her favourite food for dinner tonight: beef filet, preceded by prawns and antipasti. The filets were the smallest that Yvonne was able to find, but still big, between 140 and 210 g in size.
Chris currently has a vet student doing practical training, Licia Yeo, and of course she came along too:
|
|||||||||||||||||||||||
As I had guessed from the name, Licia's family is from Singapore and Malaysia. And like Chris Yeoh, she doesn't speak Chinese. Her family is of Teochew background. I wonder if the difference in dialect is one of the reasons both their families don't speak “Chinese”.

How to choose a DSLR
|
Topic: photography, opinion | Link here |
Message from Jenn Miller <jenn@jenreviews.email> today, although I've asked her not to on a couple of occasions:
My name is Jenn and I'm a writer at Jen Reviews. I was doing research on DSLR cameras and just finished reading your wonderful blog post: /grog/diary-jan2017.php
In that article, I noticed that you cited a solid post that I've read in the past: https://en.wikipedia.org/wiki/Digital_single-lens_reflex_camera
I just finished writing a guide that is even more detailed, updated and comprehensive on how to choose a DSLR camera - 12 factors to consider according to science. It is over 7,000 words and packed with practical tips and advice. You can find it here: https://www.jenreviews.com/dslr-camera/
I've seen this before, and it's clear from the text that it's been done automatically and with little attention to content. My diary for January has 109 articles, and it's 63 pages long when printed out. Which article was she referring to? A while back she found a nearly 50 year old reference to Kenya. I had written:
It seems that Will's father was killed in an accident in Kenya, and Moira was there at the time and saw it happen.
Now isn't that relevant?
OK, this time there's a post “How to choose a DSLR camera”. Why? There are plenty of well-researched articles already, like this list. The dpreview guides are well laid out. Do they have a “Best DSLR” article? I can't find one, and that makes sense.
Still, let's think along. Assuming I'm a beginner, what do I want from a DSLR?
OK, so what did Jen write?
What's a DSLR? She doesn't say. This quote sums it up:
A DSLR is made up of high-quality components with better accessories and features. Image quality is its only major advantage over point-and-shoot cameras.
Wow. And I wanted something flexible.
What alternatives do I have? She doesn't say. What about mirrorless? Yes, it's mentioned once in passing, but without any explanation.
Cheap or expensive? She does touch on this, but in such a vague way that I don't know what to understand.
What kind of lens? She doesn't say. She doesn't use the term “focal length” at all in the correct context, describing lenses as:
Standard lenses fall between 35 to 85mm frame.
Based on my research, standard lenses are generally used by beginners.
Wow. She seems to use “frame” instead of focal length throughout. She's implying full frame equivalent focal lengths, though it's not clear whether she's referring to prime or zoom lenses, a distinction that she doesn't even mention. On the basis of the focal lengths, I think she must be thinking of primes. It's not clear how she could imagine that these are lenses for beginners, especially since almost any DSLR nowadays comes with a zoom lens as standard.
Other things to note: she's clearly convinced that full frame is the only way to go:
Hence, the bigger the image sensor size, the better the landscape.
According to Nikon, a cropped frame cameras occupy a very small portion of the full image that’s projected on the lens. It has a 1.5x cropping measure when compared to 35mm strip of film.
What does that mean?
There's more:
For starters, advanced DLSR cameras are generally bigger in build with complex controls. While entry-level cameras feature both automatic shooting modes as well as manual so you understand how each image manipulation element works.
An entry-level DSLR comes with intelligent shooting modes and manuals you can look forward to.
Somehow I get the feeling that she has lost track of what “manual” means, but this seems to imply that “advanced” DSLRs have fewer exposure modes than entry-level models.
For starters, advanced wide-angle lenses correct the inward angle and distortion.
Huh?
Lens-shift type stabilization is more camera-specific than sensor-shift type image stabilization.
That's obvious, isn't it? Or did she get the statement the wrong way round? But are there any DSLRs with sensor-shift image stabilization? Wikipedia points me to Pentax, though that page makes no mention of image stabilization. But my experience is that sensor-shift is used mainly in (the unmentioned) mirrorless cameras.
If you want more control and performance, finding a DSLR with a manual focus functionality is essential.
More to the point, where would you find a DSLR that doesn't have manual focus? One of the “advanced” models mentioned above, maybe?
There are other sections where she says nothing at length, like “Do you need a movie mode” and “Finding Out The Image Format” (meaning choice between raw and JPEG), where she doesn't mention that you can convert raw to JPEG, but not the inverse.
“How Fast Is Your DSLR Camera?” She's talking about shutter speed:
The most common shutter speed is 1/60 as it allows the camera’s sensor to capture the scene perfectly before shutting. That said, there are versatile shutter speeds to look forward to in a DSLR. They are 1/500, 1/250, 1/125, 1/60, 1/30, and so on. Some DSLRs also feature 1 second, 2 seconds, or 10 seconds shutter speed for low-light conditions.
She doesn't mention that the fractions are of a second. But this sounds like it was written 50 years ago. Even then I had an SLR with shutter speeds between 10 s and 1/1000 s. Today even my cheapest camera (Olympus E-PM1, about 6 years old) has shutter speeds between 1/4000 s and 30 s. And 1/60 as standard? That sounds very low. She might be referring to the flash sync speed, which was round 1/60 s 50 years ago, but now it's at least 1/160 s.
Finally she comes to the term “focal length”:
Focal length: The focal length of any DSLR functions according to the shutter speed settings. If you’re setting fast shutter speeds, a longer focal length with proper image stabilization will result in a fantastic shot. But without image stabilization, opting for a higher shutter speed than focal length is essential.
This is gibberish. I think she's confusing focal length with aperture, a word that she uses only in passing and without explanation.
“Find Out About The Burst Mode”. Yes, I think she should. She seems to think that it has something to do with the self-timer. And then she goes on about battery life (and makes her only reference to mirrorless cameras in the process).
The general consensus around buying a durable DSLR with a long battery life is that needs to be recharged for more than 24 hours for it to withstand extreme temperatures.
24 hours? I haven't measured mine, but charge times be in the order of 3 to 4 hours. I can't imagine that there are any batteries that take so long. Or is she advocating leaving it in the charger after it has been charged? That won't make any difference with modern chargers.
Then there's “Find Out About ISO Settings”. The first thing to ask is what ISO means. But she doesn't say. Here an example statement:
On an ending note, a high ISO speed takes only fractions of seconds to capture a scene. This prevents camera shake, motion blur, and distortion.
In summary: this guide is worthless. I've reviewed it here because I was asked to. Jen, if you have read this far: please stop spamming me. And research your articles better in the future.
For some reason, Jen didn't publish the link to this article. She did, however, spam me again reminding me of the article. Hopefully she'll go away.

The Washington Post has reported that the Trump administration has invented a Newspeak, and that the Centers for Disease Control and Prevention must now avoid certain words: “vulnerable,” “entitlement,” “diversity,” “transgender,” “fetus,” “evidence-based” and “science-based”.

A time for radiators
|
Topic: general, opinion | Link here |
Last year we had a rather unpleasant experience when Yvonne's car suffered a burst radiator. It happened between Christmas and New Year, and the Sperbers (Ballarat Automotive) were on holiday. As a result, we didn't get the car back until 2 weeks later.
The car was due for a service again at roughly the same time, so we decided to do it early to be on the safe side. I followed Yvonne in to town with my car, noting in the process that it wasn't doing too well either: the outside temperature was over 30°, and the air conditioner cut in and out. Another repair due?
It wasn't until I got home that I noticed the water temperature gauge: off the scale. No warning lamp, but when I let it cool down I discovered that it was missing 3.5 litres of coolant. I should have noticed earlier. There has been this mess on the engine for some time:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
But that looks more like muddy water than coolant. What did they put in the coolant? There was something gooey where it had dried. What do they put in coolants nowadays? The other issue is that this looks more like a radiator problem than a hose problem.
In any case, what do I do? I don't drive the car that much—the last time I filled the tank was two months ago, and since then I have done under 250 km, including today's 60 km. But gradually the repairs are adding up: rear suspension ($750 per side), air conditioner (how much? Let's say $200 if I'm being optimistic), radiator (Yvonne's cost $500), new antenna ($100?). That makes $2,300, assuming that the engine didn't sustain any damage as a result of the overheating. According to Car Valuations, the car (a 2002 Hyundai Elantra) is worth between $1,200 and $2,700. So it's beginning to look like a new car in the New Year.

More Android TV experience
|
Topic: multimedia, technology, opinion | Link here |
I'm still not convinced that there isn't more to be gained from my Android TV, and today I did some more attempts. The entire instructions are on 2 sides of A4 paper, and they're correspondingly vague.
The biggest issue I had was that the toyshop wanted me to use voice input, but that didn't work—at all. I don't know if the microphone is broken or non-existent, but I don't really care, since voice recognition is such a long way from being useful. The instructions didn't help, of course: they didn't even mention voice input (so maybe there isn't a microphone). But it seems that enough clicks (more than 1) in the right place enable it to read the keyboard.
OK, let's install a shell “terminal”. Only two to choose from, with funny
names: $ Termux and
>Qute_ Terminal.
Where are normal names? In any
case, >Qute_ sounded more like a shell,
so I tried it. But it seems that it didn't understand
the Return Enter key: I had to tab to a tick at bottom right! What
are these people thinking? Or is it just a lack of documentation?
$ Termux was better. It didn't fill up the screen with toy junk, and it worked, showing that yes, at a certain level it looks Unix-like. I was also able to search for packages with a program called pkg—something that I thought was FreeBSD-specific, though this one is clearly different. But no NFS to be found in the packages.
Would this potentially be an alternative for FreeBSD on teevee? I'd certainly need a better keyboard than the toy Bluetooth one, but that should be possible. But without X I don't think it's worth pursuing.

Android TV: enough!
|
Topic: multimedia, technology, opinion | Link here |
Spent a lot of time this afternoon trying to make my Android TV useful. I failed.
What would I need to replace teevee with the TV itself? At the very least a shell, a web browser and software to play videos. I already discovered a couple of shells, and $ Termux seemed usable. What about playing videos? Do I have a deal for you! Every time I press the Home key, I get suggestions of what to watch, typically at the price of $2.99 per programme! The only one I found even remotely interesting was one I had already recorded from TV, and that Yvonne found so interesting that it's still on disk. And I have to wait for it to come up with its choice (as far as I can tell always the same one), which takes a considerable period of time. This isn't about technology, it's about emptying my pockets.
OK, I've heard about Kodi. Would that be a possibility? Yes, of course I can install it, and it even offers to read NFS file systems, even if it does call it a “share”:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
OK, let's try to access teevee:/spool, where most of my videos are. But it suggests a funny syntax starting with nfs://:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Entered the path name, but it didn't like it:
|
|||||||||||||||||||||||
How I love these “could be due to...” messages that apparently completely ignore the error that is reported. Network not connected? Of course it is:
|
|||||||||||||||||||||||
After a while I gave up and tried with FreeBSD, which also has a Kodi port. To my surprise, it came up with the same appearance, but it was able to access the NFS file system. What's wrong with the Android TV version? It's not telling.
Pondering that, moved on to the question of a web browser. Surprise, surprise. None of the usual names available:
|
|||||||||||||||||||||||
What's that? Tried TVWeb first (“TVWeb Browser for TV is a web browser tool of free for Android TV”). It's certainly smaller than the mainline browsers, only 4.02 MB:
|
|||||||||||||||||||||||
And it shows. Almost no settings are available:
|
|||||||||||||||||||||||
I couldn't even find a way to enter a URL. It seemed to want voice input again.
OK, what about the other one? That was even smaller, only 2.31 MB. It at least enabled me to enter URLs, and to my surprise it interpreted all my JavaScript content. Off to http://www.mozilla.org/en-US/firefox, where I discovered:
|
|||||||||||||||||||||||
I have no idea what it was thinking, but it offered no Android version. As far as I can tell, there is no version for this platform.
OK, back to try other things again. Kodi? Spent a lot of time trying, without success. About the only thing I discovered is that Kodi thinks that the display has a resolution of 1920×1080, and nothing I could do would change that.
Shell? Yvonne came past, looked at the screen:
|
|||||||||||||||||||||||
“Why does that look so funny?” That's not because there was shell output on the TV: she's seen that for over 10 years. She was referring to this old-fashioned white on black that so many people in the Linux world like. She's right, of course, so I found a way to get my .bashrc from eureka. That had a number of consequences. First, the colours were strange, considerably different from the way it looks on an xterm. It's not the display: I've been displaying X from teevee on it since I got it.
The other thing was more sinister:
|
|||||||||||||||||||||||
Dammit! I forgot to set PATH. What was it?
|
|||||||||||||||||||||||
That /data/data/com.termux/files/home looks like what I was looking for, but I wasn't able to access /data/data at all. Some non-Unix magic? In any case, there was nothing for it: reinstall. And then I found:
|
|||||||||||||||||||||||
OK, that could be fixed. But I won't bother. The whole system is useless. The complete lack of a window manager is a good example. To change from, say, web browser to shell requires going through the “home” menu, including waiting for it to think of new ways to extract money from you. What should take a fraction of a second takes about 15 seconds.
What went wrong? Here are some considerations:
One other thing that puzzles me, and which I can hopefully fix: the screen brightness varies constantly depending on the overall brightness of the scene. This is particularly irritating with subtitles. I suspected that this is what they call “HDR Pro”, something mentioned only in the advertising, but that seems to be related to specific video content. I haven't been able to find a definition.
While searching, I discovered a mention of voice input after all, in the “Problems & Solutions” section:
Voice search does not work.
OK, I'll bite. How do you pair an infrared remote control? And how do you check the “Google server”, whatever that may be.
On the face of it, I think I have enough reasons to return the TV. Should I do so? I doubt I'll find anything better, though I rather regret missing the ALDI special on Saturday: a 65" TV for $200 less than this 60" one.

Fake heuvos a la flamenca
|
Topic: food and drink | Link here |
For some time I've been planning to cook Huevos a la flamenca, but the recipes vary so much that I haven't been able to make up my mind.
Recently, though, it became clear that we have a leftover problem: lots of food that isn't much use by itself, but which shouldn't be thrown out. In particular, we had deep-fried potato, sweet potato and pumpkin, along with some boiled potatoes. How about faking heuvos a la flamenca? I decided to use the potatoes, had planned Chorizo, but discovered that it needs boiling and soaking. So I used thick bacon instead. After consideration, I decided against tomatoes, but did add some chilis, peas and spring onions. I put a couple of eggs on top and let them cook through the heat of the rest of the content. And then I managed to slide the mess out of the pan (hint: next time use a pan with lower edges) and onto the plate with minimal deformation:

The result didn't look bad, and it didn't taste bad. How close to huevos a la flamenca? Do I care?

Still more Android TV
|
Topic: multimedia, technology | Link here |
I really must have more interesting stuff to do than annoy myself with this brain-dead Android TV. But somehow I want to understand it better. I still can't see how anybody could have come up with such a stupid interface, unless they have been hiding under a stone for the last few decades (or think that their customers have).
One thing helped: I found the manual online. Surprise, surprise: it also has a greyscale title page, though there is some use of colour inside. That enabled me to search the manual and discover some things that I haven't seen before.
First, it seems to describe different hardware from what I received. How do you operate it? It describes the buttons on the TV itself:
|
|||||||||||||||||||||||
Where are they? It doesn't say. After careful examination of the TV, I decided that they're on a different TV. This one doesn't have any buttons on it. After careful reading, there are two columns: the left column is titled “For models with below buttons on the set”, while the right column is titled “For models with below buttons on the set”.
What are below buttons? Back with a mirror to look at the “set” (isn't that a term from the 1950s?) from below. At first I didn't find any buttons, but I did find the loudspeaker grilles, here the left-hand one:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Only later did I discover that the flask-like levers on the right are buttons. What do they do? At least one of them turns the set on and produces a menu. But they don't seem to match either of the diagrams, and they're completely unmarked. With some considerable difficulty I was able to get a barely recognizable photo of them (here laterally inverted to make up for the mirror):
|
|||||||||||||||||||||||
With some sorting, that's the left-hand column. But what obfuscation! I've grumbled (uncharacteristically, silently) about the difficulty of identifying buttons on monitors, but this one really takes the cake:
One point for TCL for the worst ever user interface.
On page 6 I find a potential explanation for the HDMI cable problems that I experienced last week (have I really been annoying myself for over a week already?).
HDMI1(MHL) or HDMI2(ARC) or HDMI3 or HDMI4 socket (input)The HDMI (High-Definition Multimedia Interface) socket can be used to connect a Blu-ray player, PC with a compatible video card installed, certain DVD players or a high-definition compatible digital satellite decoder. This socket provides an uncompressed digital connection that carries both video and audio data by way of an integrated mini-plug cable.Note: Only HDMI sockets with the MHL identification will support the MHL function, MHL stands for Mobile High-definition Link, and allows you to link an MHL capable mobile device to the television.
No mention of what ARC means. From Wikipedia, it seems that it stands for “Audio Return Channel”. Not what I need, but clearly I'm going to have to read up on HDMI compatibility.
On page 8 I found the first reference to voice input:
|
|
|||||||||
|
|||||||||||||||||||||||
OK, let's try that. But I can't! My remote control looks nothing like the illustration, and try as I might, I couldn't find a microphone symbol. I later found an illustration of my remote control on the previous page:
|
|||||||||||||||||||||||
It's also interesting to note that the text in the online manual differs from the one in my printed manual, suggesting that they've been working on this area. Only the online version contains the additional information
When using the MOUSE or VOICE CONTROL button for the first time,you will be prompted to pair the remote with the TV. Please follow the on-screen guide for paring instructions.
So: what's the story? Peter Jeremy had already noted and interpreted the first point in yesterday's troubleshooting guide:
Check if your remote control has been successfully paired with your TV.
Why does the remote control need to be paired (or is that “pared”, as they mention elsewhere?)? Peter assumes that the microphone is in the remote control, and that makes perfect sense, since it's near my voice. But how does it work with the other remote control? Not at all is my guess, and that's a violation of the specs. If I could find a better TV at a reasonable price, I would bring this one back. Again, stupid me for not buying the ALDI TV on Saturday. At least I would have then been able to make a choice without any financial obligations.
Regarding the image brightness, received email from Ian Donaldson. who tells me that the feature (if that's the right description) is called “local dimming”, though on cheaper models, like this one, the term “global dimming” might be more appropriate: the screen, or sections of it, dims to improve low-illumination contrast. On Samsung TVs, Ian tells me, you can control this with ”Smart LED” (Controls the local dimming effect), and “Dynamic Contrast” (Dynamically adjusts contrast depending on the scene). I'll have to see if this is even available on my TV.
As if that weren't enough pain, I did some more playing around with Kodi to see why I couldn't access NFS file systems. I failed, at least in part because there seems to be no way to edit or delete entries. But I'm beginning to wonder whether Kodi presupposes kernel support for NFS, and is too polite to complain if it's missing.
Peter Jeremy attempts to defend Android TV with the claim that most users don't want a keyboard. He might be right, but I'm by no means certain. Certainly the fact that people have given up desktop computers for laptop computers, then laptops for mobile phones, in each case paying a heavy price in ease of text input, points in that direction. But why did the Marriotts next door want a keyboard on their new TV? They're not technical people. I'm assuming that they find it the easiest option.

Daily Android pain
|
Topic: multimedia, technology, opinion | Link here |
Gradually I'm coming to understand what little there is to know about Android TV, but there are still details to follow up on.
Somebody recommended VLC for Android. That's a program that I have used before, so it seemed reasonable. But of course it has been dumbed down for Android, and once again I found myself facing guesswork—and the lack of an online help window. The complete lack of windowing on Android TV borders on the insane. Yes, I could have gone and got euroa, my Microsoft laptop, but I pressed on with guesswork. And how about that, I was able to establish a connection to eureka using SMB (really Samba). And for the first time I was able to view a video on the box, after only 9 days.
Was it worth it? No. It seems that VLC doesn't really want to know about the remote control. But then the controls on the remote control are pretty much useless:
|
|
|||||||||
Start, freeze, stop, fast forward and fast backward.
Fast forward and fast backward? What good are they? None any more. They were a way of searching on obsolete mechanical devices such as video cassette recorders. With digital devices they're useless, as I discovered about 12 years ago. Instead it's easier to jump forward specific periods of time. But, as I had noted last month, I can't find a way to get VLC to do that via keyboard input. The only option was dragging with the mouse, which doesn't work here because the thing doesn't even have a mouse.
As if that isn't bad enough, it also doesn't seem to remember positions when stopped. If I watch part of it and stop it, it starts again from the beginning. The only way to get to where I was (if I recall where that is) is to go there at about 2× speed, which for some reason is the maximum.
OK, what about Kodi? My experience with it was less than satisfying, but that was because I couldn't get it to find very much. What about with SMB again? Yes, that worked. And I was able to use undocumented arrow keys to jump forward and backward as I wanted. But the smallest step was 10 s in either direction. I've been quietly grumbling about mplayer, where the minimum jump appears to be about 3 to 5 seconds, depending apparently on the stream structure. But this is much worse, and there doesn't seem to be any way to change it. And once again it doesn't save the position when it stops.
While messing around with the “menu system”, found an app for displaying Deutsche Welle programmes. That's better than it sounds, since their web site is so broken that it's almost impossible to find the news.
Here it found the news with no problems. That's the good part. But it completely ignores the remote control! The only thing I can do, with the left and right arrow keys, is to bring up an image of a virtual remote control and position on the keys I want, then press another key (OK? Enter?) to select it.
That must take the cake for one of the most clumsy positioning methods I have ever seen. But in general it seems that Android TV combines the inconvenience of old-fashioned TV (once the result of necessity) with the inconvenience of a castrated digital interface that doesn't even address the advantages that the new medium could offer.
Apart from all of this, there's another reason not to watch live TV: congestion. I have a 25 Mb/s Internet downlink, but sites like Deutsche Welle are 30,000 km away, so there's a minimum latency of 200 ms. In practice, it's more like 350 ms, and from time to time something gets stuck in between and causes seconds-long delay. It would be so much easier just to download the file and display it with mplayer, like I currently do.

Buying votes, Trump style
|
Topic: politics, opinion | Link here |
One of the most important things about democracies is that people vote according to their conscience, and not for perceived advantage. But the President of the United States of America doesn't care about that. After he destabilized the Middle East by recognizing Jerusalem as the capital of Israel, the UN Security Council held a vote which basically showed that there should be no vetos, at least not by a single country. So the otherwise unanimous vote failed with the US veto. To my surprise, the UN then convened an emergency special session of the General Assembly to vote on the matter. There there can be no vetoes.
Does that worry Donald Trump? Of course not. He's a Big Man. You vote for the resolution, you lose foreign aid. If that isn't a blatant attempt to buy votes, I don't know what is.
How long will it take the USA to regain the international trust that Trump has thrown away for nothing? Will it ever?

Piccola leaves house

It's been over a week since Piccola got the shock of her life. What was it? No idea, but it clearly happened outside, and since then she has no longer left the house beyond the immediate vicinity of the front door. Today she finally went further and spent about half an hour in the hayshed and (I think) the garden shed. But then she was back again.

Dogs going begging

They have very different temperaments. The one in the middle photo is called Sasha (but female), and we decided that she might adapt quite well to a new environment, but the other (Mishka, which Yvonne tells me is Bulgarian for mouse) is quite a complicated personality, and it looks as if she might be much more difficult to place, especially if she has to learn to get along with other animals.

Olympus firmware upgrade
|
Topic: photography, technology | Link here |
Release 1.4 of the firmware for my Olympus OM-D E-M1 Mark II was released a couple of days ago. To install it, I had to connect the camera to dischord, my Microsoft box, because Olympus, in its wisdom, will only install firmware with its own programs (in notable contrast to Canon, who just place it on the storage card and let the camera install it).
Firmware installation is now more complicated: first you the program saves the
camera settings, then it installs the firmware. Then you power cycle the camera and reload
the settings. I've done this before, and modulo the glacial speed and the inconvenience, it
just works.
Today it was different. After power cycling the camera, the program no longer recognized it. Why not? It was too polite to say. Camera wedged? Program broken? Hardware issues between camera and program?
I was able to confirm that the camera was still working, at least enough to show me that it now had the latest firmware. Stopped the program and restarted it, and was able to reload the settings. So it looks like “broken program”. Yet another reason not to rely on manufacturer's programs for this sort of thing.

Mowing the lawn?

The lawn is growing very high, and I really should mow it. Garry Marriott next door has spent much of the last couple of days mowing his, and I really started preparing for it.
But then I noticed what was growing there:

It's difficult to see what's going on from that viewpoint. The left and right look very different:

On the left, some kind of wildflower has taken over and, to a large extent, prevented the grass from growing: a natural ground cover. There are two kinds of yellow flowers there, the larger ones that superficially resemble dandelions, and smaller ones that appear to belong to the Fabaceae family. They're spreading through the garden. but they're quite pretty. Do I want to get rid of them?
Somehow we have a large number of (wild?)flowers this year. Another one are these pink flowers:

Diary: quarter life

Topic: history | Link here |
Seen in my calendar mail today:
I've been keeping this diary for a quarter of my life! In fact, I've been there before, on 2 October 1967. More to the point, though, including my paper diary of the 1960s, I've been keeping a daily diary for 25 years (300 complete months, 93 between 1 January 1963 and 30 September 1970, and 207 months between 1 September 2000 and 30 November 2017), well over a third of my life. It's been an interesting exercise. How I wish I hadn't stopped in between!

XXX TV
|
Topic: multimedia, technology, opinion | Link here |
Yvonne off to town today for Pilates. She called me back from ALDI: she had been looking for one of the TVs they had on offer last weekend. I told her that it was a hopeless case and that she shouldn't waste her time—but she had found one! I later heard from Jamie Fraser that at his local shop in Horsham they even had four of them. That's quite unlike ALDI's electronics specials, especially not directly before Christmas. I wonder if the size was an issue.
So she brought it back (a Bauhn ATV65UHD-1217, according to the package), and with a 165 cm (65") diagonal), and we swapped out the TCL:
I'm not even going to try to add a URL for the new TV. The end of the model number (1217) suggests this month, and these things are here today, gone tomorrow.
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
The size difference isn't immediately apparent, but it's 12 cm wider at the diagonal (run the cursor over an image to compare). Installation was marginally more complicated than with the TCL: the package is so tight that we could hardly get it out. The feet look considerably more solid than those of the TCL, but of course they're asymmetrical:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Which side goes in front? The instructions don't say, nor even mention the fact. They just illustrate (badly) that the longer part goes in front.
Setting up was relatively straightforward, and within half an hour I had the channels scanned and X running—sort of. The image overflowed the screen by about 20 pixels in each direction. Tried playing with xvidtune, but that's an old, worn-out program. It couldn't apply any mode line, not even the one it was running with.
OK, this is a nVidia graphics card, and they supply a configuration program appropriately called nvidia-config. But though I could do some tweaks with it, there was nothing that changed the image size or alignment.
This is hardly the first time I've seen this kind of issue. Over 25 years ago I wrote an article on the subject, though you'd think that in these days of EDID it would be unnecessary. And sure enough, in the /etc/X11/xorg.conf I found:
How about that, that's identical to the mode line I was running, modulo dot clock (now 148.5 MHz, then 150 MHz). And clearly I had had similar fun with the previous model 5 years ago. OK, try that mode line, but it didn't “take”: the EDID overrode it. Started X again with the -logverbose 6 option and found:
Somehow EDID has grown since I last looked at it, notably with the CEA-861 extension block. But the more obvious details are interesting. Look at the name! “XXX TV”. Yes, I use XXX frequently to indicate things I should fix. Here, Yet Again, a working title has escaped into the wild. And the rest of the EDID looks dubious: image size 0×0, manufacture date Week 1 2015, product ID and serial number...
And sure enough, the device wants:
And that's what it got. But it can't handle the input! I wonder how many people have trouble with this. In my case, I need to override the EDID and put in my own timing. But that's for tomorrow.
How does it compare to the TCL? It's missing a lot, including nearly all the irritating “features” of the TCL, like dimming and the entirety of its terminally broken software. But then, it's not a Smart TV. In fact, it's dumber than the last one, which at least had Internet connectivity. This one doesn't have any networking at all.
Is that an issue? I don't think so. I recently read an article about Android TV set-top boxes. I could buy one for the price difference between the two TVs. But that article also confirmed all my issues with Android TV, without giving any obvious advantage. Until proof of something better, I'll keep teevee as my set-bottom box.
On the other hand, it looks higher quality than the TCL. The stands are considerably more solid, the instruction manual is at least glossy and in colour (and, surprisingly, easier to understand). And the manual controls are easy to find and well labeled on the right hand side of the TV. Here the Bauhn, then the excuse for controls under the TCL, where you can barely find them:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
About the worst thing about the Bauhn appears to be its power consumption: according to http://www.energyrating.gov.au, it uses 594 standardized kW/h per year, compared to only 310 for the TCL. That's not just the screen size. TCL do a 65" model as well, and it uses 510 kW/h.

X on Bauhn TV
|
Topic: multimedia, technology | Link here |
Spent some time today playing with X setup on the new TV. For some reason the IgnoreEDID option didn't help, and I kept ending up with the same old mode lines.
But then I thought a bit further. This isn't an analogue system. The data comes in from the HDMI interface and is immediately processed. In this particular case, the TV needs to know that it's 1920×1080 and upscale it to 3840×2160. The sync delays are irrelevant.
So why was it overrunning the screen? That's typical of analogue systems, where the sync pulses and delays are necessary for a correct display. I went looking in the device menus, and sure enough, I found a setting: HDMI Mode. Possible settings were Auto, Video and PC. It was set to Auto. I set it to PC, and how about that, the picture fitted.
What's all that about? Why should the size of the display depend on the input? Clearly the recognition is broken, since Auto didn't work. But I can only imagine that Video really does cut off the edges, only it's not so obvious. In any case, all is now well.

The Christmas that wasn't
|
Topic: general, food and drink, opinion | Link here |
Working up to Christmas is usually hectic, but today somehow nothing happened. Instead of a goose (where do you get them in Australia?), turkey or ham, we decided to try the flavour of the year: multiple birds stuffed into each other. There's a thing called a Turducken, offering interesting possibilities of multilingual mispronunciations, and which is apparently better known in other parts of the world. It comprises chicken, duck and turkey.
But why settle for only three birds? ALDI had a four bird roast (atypically without a more evocative or obfuscatory name) which also included (a ?) quail and was barded with bacon:
|
|||||||||||||||||||||||
That was supposed to take “40 minutes per 500 g”, clearly easier to say than “80 minutes per kilogram”. But it didn't: it weighed almost exactly 2 kg, but it hit the 78° mark after only 120 minutes.
And the result? Not bad at all, but because of its composite nature it wasn't possible to cut it into slices: they just fell apart. I needed to cut slices of about 2 cm thickness. Here what it looked like at the end:

What happened to Christmas?

Topic: general, music | Link here |
It has been years since we really celebrated Christmas. After all, we're not Christians, our daughter Yana left home years ago, and we're not overly sociable, so there's no obvious difference. But I had always enjoyed the food and the music. This year we had food, but were was the music? It's not just us: we listen to two different radio broadcasts (ABC Classic “FM” and Radio Swiss Classic), and neither of them had any Christmas music. Why not? In the end I dragged out Bach's Christmas Oratorio and listened to that, but somehow the whole day was even more of an anticlimax than normal.

Piccola braver

Topic: animals | Link here |
Gradually Piccola is becoming brave enough to go outside again. She didn't want to first thing this morning, but later she went out twice for an hour or more. The second time I found her in the hayshed, and she went into the shed next door and hid.
Why? Not from me. But I had seen a couple of magpies outside: it seems we have a family living in the trees near the entrance to the house, and they have taken over our garden as a playground. They can be aggressive at times. Can it be that they had attacked her, and that was what scared her so much? Certainly being attacked from the air is a completely different situation from being chased on the ground.

I've been pondering about how to calculate parameters for focus stacking for nearly a month, without coming to any really concrete conclusions. But then, nobody else has either, and they're still taking good focus-stacked photos.
OK, time to try again. I've established that I can use the Feelworld FW760 with the focus stacking mode of Olympus OM-D E-M1 Mark II by turning to AV input before taking the photo. Otherwise the camera refuses to focus stack.
With this setup I finally got a worthwhile photo of a Hibiscus rosa-sinensis:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Which of the two photos? They're both the same, just processed differently, both with Zerene. I can't make up my mind which to choose, so for the moment I'm making two versions of each image. Run the cursor over either image to compare it with its neighbour.
Then I tried a more difficult candidate, these tiny little flowers growing in the garden. The flowers themselves are about 1×2 mm in size:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
I had never noticed the hairs on the plants before. They must be about 20 to 50 μm thick.
Encouraged by that, I tried a few more of the Hibiscus:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
The second one was taken with extension tubes, and the magnification must be about 1.5:1. There's clearly flare there, though I don't understand why that should be related to the extension tubes. Next time I'll try without backlight. On the other hand, focus stacking appears to have worked despite the (no-name) extension tubes.
The third image shows an issue that I haven't solved yet:
|
|||||||||||||||||||||||
I had gone to some trouble to set up the camera so that all 5 anthers were in focus. But the ones in front weren't. Why not? Ultimately operator error, of course, but for some reason the focus peaking failed, both in the camera and in the monitor. It must have something to do with the contrast, but it would be nice to have adjustable threshold focus peaking, like I've seen in some smart phone apps.

Garden recovery

Topic: gardening | Link here |
It's been nearly two months since we bought some colourful and expensive clematis plants. Here then and now:
|
||||||||||||||||||||||||
|
|||||||||||||||||||||||
Surprisingly, today's photo is an improvement. After planting basically nothing happened. The flowers faded, the plants all around started growing. The plant on the right is a Mandevilla laxa, which I had thought was dead:
|
|||||||||||||||||||||||
But all that happened with the clematis, both of them, is that they didn't die.
But now there are signs of improvement. On the plant above, the broken-off stem now has new growth, and the nodes are now showing buds:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
The other one has progressed differently. It showed a few shy shoots from the beginning, but now they're getting longer:
|
|||||||||||||||||||||||
So I have cause for hope. To be observed.
In addition, our miniature waterlily has developed no less than five flowers:
|
|||||||||||||||||||||||
We've had the plant for nearly 9 years, and though we looked after it in Kleins Road, we never got more than two or three flowers at a time. Maybe it's warmer in the new trough.

TCL TV: Deaf
|
Topic: multimedia, general, opinion | Link here |
I've finally come to the conclusion that my new TCL 60"(152cm) UHD LED LCD Smart TV doesn't support voice input, despite all claims to the contrary. Finally called up TCL on 1300 738 149 and spoke to MJ (or similar pair of initials). Over a total time of 17 minutes, received very little information, but enough: no, my TV as delivered does not support voice input. For that I need to buy the other remote control for $90, nearly 10% of the total price of the unit and nearly double the price of an Android TV set-top box. Alternatively I can use the arrow keys to input information.
That's not what I was promised, and appears to be in violation of the Trade Practices Act, which I discover is now called the Competition and Consumer Act. Asked to speak to a supervisor, but they were all in a meeting. Some supervision. She suggested that I called back later, but I asked her to ensure that her supervisor called me back by close of business today. Got the call reference number, 38729, and waited. No call back, but that seems normal.
What's wrong with this picture? Off to gather evidence, and in fact I did find a reference on the TCL web site:
Search for your favourite apps, music or movies, just by speaking into the remote control!****Only X2 models include free voice control remote. Voice search remote additional purchase required for C2 & P20 models (not compatible with 43P20US)
I didn't see that when I researched things two weeks ago. So I went checking. Many things suggest that the TV should have voice input:
It runs Android TV, which relies on voice input for most functions. The lack of primary functionality should be stated prominently.
Nobody warned me about this issue when I bought it.
There's no mention of this restriction in the instruction manual.
The Good Guys' web site doesn't mention the restriction.
The packaging of the TV clearly shows a microphone symbol:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
Even the restriction of the remote control doesn't mean that it's necessary: the TV has sound input (via the HDMI ARC), so it would be reasonable to assume that it also has a microphone input (which, however, it doesn't). But one way or another, this contradicts what's on their web site.
In any case, that's the last straw. First I need to calm down, then contact the Good Guys and arrange a return.

Piccola recovering?
|
Topic: animals | Link here |
This morning, for the first time in over two weeks, Piccola went out of the front door in the early morning and walked away from it.
I came back a few minutes later. She was back, sort of, under the Leucospermum cordifolium about 10 m from the front door:

She kept looking around her, adding weight to my hypothesis that it might have been a magpie that scared her. As soon as I opened the door, she ran in. But clearly things are getting better.

Flash modeling lights
|
Topic: photography, opinion | Link here |
My Godox DE 400 studio flash units have a strange kind of modeling light:
|
|||||||||||||||||||||||
They're clearly shaped like that to avoid obstructing the flash tube, the glass ring round the base of the lamp.
They're conventional incandescent (or maybe halogen), so their life is limited, especially since they turn on and off every time the unit flashes. Last month one of them burnt out, and I considered replacing it with something else, like an LED lamp. But where do I find one the right shape? So I ordered two replacements.
Today they finally arrived, and only then it occurred to me that I should compare just how much light would be lost by using a normally shaped globe. So I tried with the standard modeling light, a low-power fluorescent and an LED globe (run the cursor over any image to compare it with its neighbour):
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
The results were interesting: less than the fluctuation from one flash to another. The flash exposure reported by the exposure meter ranged from f/5.6+2 to f/5.6+7, but not the way you might think. For each setup I took four shots. Here the results:
So the difference between the special modeling lights and normal LED globes is about 0.1 EV. Interestingly, no lamp at all appeared to give the worst results! There are probably other things in play here, but in practice it means that the illumination hardly suffers at all. It would be more difficult to measure the evenness of the illumination, of course.

Returning the TV
|
Topic: multimedia, general, opinion | Link here |
I've had the TCL 60"(152cm) UHD LED LCD Smart TV for over two weeks now, high time to return it. But first I need to confirm that they will take it back. Called up The Good Guys in Ballarat on 5330 8444 and got no reply. Repeatedly. Any other way to contact them? Only by filling out a form on the web, signing away your personal details and answering a Captcha. No, thanks, guys. That's not good.
On the fourth time I finally got a reply by a good semblance of a human being. She put me on hold looking for Danny, and after 5 minutes was told that he wasn't reachable, but would call back. He didn't.
Oh well. At least I have a paper trail.

Unhappy Tropaeolums

A couple of weeks ago I planted three black Tropaeolum seeds, mainly to see how well they germinated. They did well—until a day or two ago. Now they're looking surprisingly unhappy:

What's causing that? That's fresh garden soil, they're kept moist, and they're not subject to too much sun. The holes suggest that some insect has got at them, but is that a cause or effect?

Accepting the Israel takeover of Palestine
|
Topic: politics, opinion | Link here |
Interesting article in the Times of Israel today. David Friedman (nomen clearly non est omen) wants the US State Department to stop referring to the territories of Palestine occupied by Israel as “occupied”. It doesn't report what he thinks they should be called, and the only alternative I can think of is that he considers it part of Israel.
This nonsense with the US recognition of Jerusalem as the capital of Israel can be excused in the fine print, as I noted a few weeks ago. Yes, they have given up yet another piece of their reputation: no longer an honest broker in the “peace process”. But this one is different: if substantiated, it means an acknowledgement that the status quo is all you get. No Palestinian state: the territory isn't “occupied”, it's part of Israel.
When will this end? And how?

AV cables for Olympus
|
Topic: photography, opinion, technology | Link here |
The field monitor for my Olympus OM-D E-M1 Mark II works relatively well, but it's made more difficult by an apparently deliberate bug in the camera firmware that switches focus stacking off when an HDMI monitor is connected. How about the composite video output? I had one for my E-30 years ago, and used it to connect a viewfinder to the camera. Where is it? After some investigation, I discovered that it came with the camera, so it went with the camera too. And more modern models don't have that cable.
OK, they cost almost nothing. Off to take a look. It took me forever. I couldn't find any cable advertised for the modern mirrorless series, just cheaper series. There appeared to be two different models: “AV /TV Cable for Olympus camera CB-USB7 FE-5500/5010/5020/5000/4010/4000/3010_sx” and “12pin av tvout Cable 2rca cord for Olympus CB-USB6 FE-200 FE-4020 FE-4030 5030”. Neither had any mention of the mirrorless cameras at all, but looking at the pictures of the connectors suggested that the latter was the one I was looking for. On further investigation, I found that CB-USB6 and CB-USB7 are the Olympus part numbers, and further investigation again brought me to Olympus' USB Cable Compatibility - Digital Cameras page. It mentions about 10 different cables, including CB-USB6 for the newer DSLRs, including mine, CB-USB8 for the E-M1 and E-PM2, and CB-USB11 for the E-M1. OK, the cable for the E-M1 Mark II is clearly very different—it's a standard USB-C cable. But I had thought that all the other cameras used the same cable. What's the difference between CB-USB6 and CB-USB8?
I still don't know. Olympus isn't telling, and neither is anybody else. I did find some pinouts here:
Pin
NumberPin
NameDescription 1 USB D+ 2 USB D- 3 AUDIO OUT mono 4 SHUTTER 5 VIDEO OUT 6 GROUND 7 USB +5V 8 FOCUS 9 USB GND 10 GND 11 Video GND 12 enable video output pull to ground to activate shell GND
In the process I discovered the site http://pinouts.ru/, which is in English and could be useful, though in this case it just led me to the previous URL. And then there's a pictorial guide of how to do it yourself. Only some time later did I notice on page 9 of the handbook for the E-M1 that the USB cable is specified as CB-USB6. So whatever the difference is between CB-USB6 and CB-USB8, it must be minor.
OK, order a cable. Done! And then it occurred to me that I really wanted a cable for the E-M1 Mark II (CB-USB11), not E-M1 Mark 1. Never mind, it only cost $2.66, and it might come in handy for the other cameras.
Later still, I went looking for AV cables for the E-M1 Mark II. There aren't any: the camera doesn't have an AV output.

More sourdough issues

Topic: food and drink, opinion | Link here |
Time to bake bread again. But the starter I planned to use didn't inspire confidence. It's one of the two on the left:
|
|||||||||||||||||||||||
What is that stuff? I've been told that darkening on the surface of a starter is not a problem, but here I'm seeing specific patterns, including triangular ones reminiscent of the Mercedes-Benz star:
|
|
|||||||||
To be on the safe side, I used the one on the right. But that's not a solution. This is the new starter that I first used on 19 October, and the two on the left date from then. It should have kept better than that. In the past I've kept starters for 9 months with no problems. What has changed? The bacterial environment?

eBay: 1 point down, 1 up
|
Topic: general, technology, opinion | Link here |
A month and a half ago I ordered blindfolds for covering my face when sleeping, from three different sellers. Two of them arrived after average timing, but the third,which eBay Australia tells me was bought on “11/20/17 4:...”, didn't. Checking the item showed amazingly detailed tracking for something that cost $1.00 including postage. It showed:
|
|
|||||||||
The texts are strange, as are the times, but it's clear that the trail stopped over 3 weeks ago, and that they consider it still “in transit”. OK, contact the seller and ask for resolution.
But eBay have changed their web site again! And when I finally fought my way through to the appropriate page, I got another “eBay cannot refund your purchase” or some such, explaining that real estate and classifieds (whatever they are) are not covered by the money-back guarantee.
Dammit, they've broken things again! But this time I was given the chance to “chat”. Took that, and of course they found that I could, indeed, claim compensation. And for the first time I have a paper trail. In addition, it's easier to get your point across like that. One plus point for eBay, roughly making up for their latest breakage.

Dinner with Melanie and Will

Chris Bahlo's sister Melanie is here again, this time with her son Will:

We had Wiener Schnitzel, preceded by prawns in aspic. Problem: Melanie doesn't eat fish. We need to keep a list of what our few guests like to eat. We've already served Nele Kömle Pavlova twice, though she doesn't like fruit.
How much food? Plenty. Especially if there's a little boy there, who ate more than any of us. I didn't make enough chips, only 450 g. I base my estimates on 100 g for normal people and 70 for Yvonne when eating only a single course, so with three courses that should have been plenty.

Dinner panorama: still not there
|
Topic: photography, opinion | Link here |
I've been trying to take panoramas at the dinner table for years. The first attempt was some years ago, and I messed it up by setting the focal length of the Zuiko Digital ED 9-18 mm f/4.0-5.6 incorrectly. More recently I've been trying with the Vanguard ALTA PRO 263AT, which gives a better perspective, but I'm still plagued by lighting issues. My current one is that the flash trigger for the dining room flash died. I found another, but it's anything but ideal. The flash is places on top of a corner cupboard:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
But the trigger sticks out the back, made worse by an adapter plug, so it won't fit there:
|
|||||||||||||||||||||||
Instead I put it on the edge of the cupboard next to it, with the adapter sticking over the edge:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
And that was pointing in the wrong direction, so it didn't light evenly.
Clearly this is an issue with the way I'm using the flash. It's designed to be mounted on a stand, where it's easy to point it in any direction. But I can't find anything small with the appropriate mount, though I should probably try again.
Instead I used the mecablitz pointed upwards and slightly towards the subject. And that worked, sort of, but somehow it's still not right:
|
|||||||||||||||||||||||
The other issue was focus. Yes, it was acceptable, but I had the camera set to autofocus, and the result was that the foreground was more out of focus than the background. Back to manual focus next time: after all, all people are the same distance from the camera.

Talking about TV series with Melanie after dinner. She came up with the Almighty Johnsons, which sounds interesting enough. But then she also likes The IT Crowd, which we rejected violently six months ago. I'm surprised that anybody likes the series, but it seems that some people do.

Tracking the sourdough infection
|
Topic: food and drink | Link here |
Yesterday's problem with sourdough infection had me wondering. Where did it come from? And only today I found the answer. I let the starter and the bread rise in a covered plastic container that keeps the moisture in. And looking at the container today, I saw:
|
|||||||||||||||||||||||
|
|
|||||||||
That's clearly some kind of mould, and it's not hard to imagine it infecting the starter in the 18-odd hours that it's in there. Yes, I can clean the container and disinfect it, but it would be simpler to just cover the sourdough with plastic foil while it's replicating.

Studio flash mounts
|
Topic: photography, opinion | Link here |
How do I correctly mount the studio flash units I have in the dining room and lounge room? They're designed for mounting on stands, and I discover that the fitting is called a baby pin, a term with great potential for misinterpretation:
What I need is one with a fitting to screw onto a wall. But finding them is a real pain. I can buy a cheap lighting stand on eBay starting at about $13. But eBay doesn't seem to have anybody interested in selling more exotic fittings. I found something suitable at B&H for US $11.95, slightly more than the lighting stands I could get on eBay:
But clearly it's a quality unit: it even comes with an 8 page, 250 kB user manual of modern kind. OK, that's good. How much space does the plate take up? How big are the holes? Ah, it's not that type of manual: it has safety information, and the “specifications” mention material and weight to the nearest 113.4 g, but nothing useful like size of plate or details of mounting holes:
|
|||||||||||||||||||||||
|
|||||||||||||||||||||||
“Keep this unit away from children”. “Do not attempt to disassemble or repair the equipment”. Why do I get the impression that this is generic stuff? Still, it looks like it's the only game in town, so I'll probably order some. And B&H gave me the answer I was looking for: the plate is 8×15 cm in size.
