Correcting Google Maps
Topic: general, technology, opinion Link here

I'm gradually coming to the realization that GUIs are more difficult than I can understand. I completely lack an overview over Android and iOS, and menu structures in Microsoft and similar baffle me.

Am I stupid? No, only stubborn, I think: I expect to be able to understand them. Most users of these devices, I suspect, learn individual tricks from others, and never understand the overall structure (you could even claim that this applies for the developers).

Today I had another issue, related to my photos of the Solanum laciniatum. I took them down Harrisons Road, but Google Maps claims that it's Stones Road. It does that for the eastern end of Bliss Road too.

OK, I can fix that. Just select “Report an error” on the map. Oh. It's gone. Wasn't it there once? Mess around and finally find “Feedback”. OK, feedback that I can't find “Report an error”. Oh. It's now under “Feedback”. OK, report wrong road name. Mark whole road? Yes, it will do that, according to its definition of “Stones Road”, including the stub end of Bliss Road.

How do I fix that? I still don't know if I can. Marking the “road” selects a mid-point and doesn't appear to allow me to adjust the ends. Dammit, it's better like that. SUBMIT.

Server error. Please try again”. What a clear error description! So I tried again. And again. And finally with a different browser, which apparently found favour in the eyes of the server. Now let's see what they do with it.


Solanum laciniatum photos
Topic: photography, gardening, opinion Link here

Back to Harrisons Road today and cut off a twig with a few flowers from one of the bushes there. Back home and did some focus stacking, once again not to my satisfaction. Here are out-of-camera photos of one flower that was interesting because it has two stigmata:

It's still not as sharp as I'd like; I need even more depth of field. And it's a real pain trying to estimate the number of shots needed.

In passing it's interesting to note the use of flash. I had two possibilities: the studio flash at full power (400 J) or my ring flash at 1/16 power. The former would have given me enough light for f/8 at 1:1 magnification (really v/16), while the latter gave me enough light for f/16 (v/32). But the real reason was that I didn't think much of what would happen to the studio flash tubes after potentially hundreds of full power flashes.


Dan Murphy second guesses
Topic: food and drink, technology, opinion Link here

Email from a Dan Murphy's today, offering me a case of Adelaide Hills Sauvignon blanc wine for a price that I'm prepared to pay, shipped to my door. Clearly something has triggered their offer. Was it the three individual bottles that I bought last week? Or somehow feedback from the seller of the wine I bought on eBay? In any case, worth trying out, so I ordered one.


Not these tones!
Topic: multimedia, technology, opinion Link here

Now my old phone is back up and running, including the SIM card that I bought for Ruth Viebrock last November, the obvious thing was to set the ring tone. OK, try to get the Carl Maria von Weber's Andante e rondo ongarese ring tone that I'm using on the other phone. Uploaded it. Tried to set it. Not to be seen. It seems that I need to press ADD at the bottom of the screen on this device, and then somehow find the /storage/sdcard0/Music/ directory. The Android way seems to be to look for what the music player knows, but that wasn't much. In the end I tried the time-honoured (and Android-deprecated) method of tree climbing. One more brown mark for Android.

But that's not ideal. Two phones with the same ring tone? That way madness lies. OK, what else can I use? I thought of various Schubert melodies from „Die schöne Müllerin“, but then it occurred to me: the choral introduction in the last movement of Beethoven 9: „O Freunde, nicht diese Töne“ (“Oh friends, not these tones”).

OK, how do I do that? First I need something less clunky than what I had used before (mplayer and ffmpeg). Google search for “FreeBSD graphical audio editor”, and discovered that that's the purpose of audacity. OK, there's no point trying to install it on my down-rev eureka. Does it work on eureso? Yes, no issues. Well, one: I don't have any audio output for eureso. OK, try on teevee. It was already installed, if that's the word:

=== grog@teevee (/dev/pts/2) ~ 10 -> audacity
(Audacity:83821): Gtk-ERROR **: 18:05:17.385: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported
Trace/BPT trap (core dumped)

What went wrong there? OK, time for a ports upgrade. And at the end I had about the worst situation I could imagine:

=== grog@teevee (/dev/pts/2) /usr/ports/distfiles 12 -> swissclassic
Shared object "libva-x11.so.2" not found, required by "mpv"
1371010 -rwxr-xr-x  1 root  wheel  1806056 23 Feb 12:35 /usr/local/bin/mpv

=== grog@teevee (/dev/pts/2) /usr/ports/distfiles 18 -> mplayer
Shared object "libva.so.2" not found, required by "libavcodec.so.58"

None of the important ports worked any more. Where did libva.so.2 go?

=== grog@teevee (/dev/pts/2) /usr/ports/distfiles 19 -> locate libva.so
/usr/local/lib/libva.so
/usr/local/lib/libva.so.2

And of course nothing was there. Why not? OK, try deinstalling and reinstalling it:

That way madness lies! How about upgrading it?

Something's seriously wrong. I have the log of the port upgrade process. I wonder if that will shed any light on the problem. In the meantime, is there a way to remove a package without removing its dependencies? I know a way, but it's not canonical:

=== root@teevee (/dev/pts/9) /home/grog 21 -> cd /usr/ports/multimedia/libva

All that pain for nothing! And how do I fix it?

As if that wasn't enough pain, I discovered that I also had a functional (if somewhat down-rev) version of audacity on eureka, so the whole effort hadn't been necessary. Played around with that. Another opaque GUI to get to know, but it looks as if it will do what I want, once I understand how to use it. The clip is from 5:39.25 to 6:13.67 on the Christopher Hogwood recording.

It also didn't move for the whole time I observed it, though much later it was gone. And not for the first time I've noted that this kind of photo needs more preparation. I really needed a flash of some kind, but that would have reflected.


Multipurpose developer
Topic: photography, food and drink, opinion Link here

Interesting article in Digital Photo Review today: a beer that you can use to develop film (or should that be a developer that you can drink?). It seems appropriate for some beers I have had: barely drinkable, it's good to know that you can use them for something else.


Arne Koets clinic again
Topic: animals, photography, opinion Link here

Yvonne off today to another (maybe the last) Arne Koets clinic, this time in a place that I had never heard of: Sulky. It seems that there is a certain amount of bad blood amongst the riding community about the arrangements, and that Arne is also not very amused.

Yvonne was on in the afternoon, and her slot was postponed. She wanted me to come and take videos, but somehow I misunderstood and didn't arrive until half way through her lesson. The place isn't much to look at:

The photography was not very successful. Once again it's one of these horrible arenas with a roof and no sides, meaning that getting any kind of exposure is a matter of luck. And it seems that Arne had said most of what he wanted to say to Yvonne, so I didn't get much of that. And I've gradually come to the conclusion that the Olympus OM-D E-M1 Mark II is no good for videos of horses. For all they hype, the autofocus is useless; I might as well have used a mobile phone. About the most interesting thing was Chris Bahlo with her five-legged stallion and mediaeval saddle:

Times have changed since then. How about a good meal the way we did them in those days: fillet steak with garlic butter, followed by hot ice cream with raspberries? Did that and discovered that our tastes have become more refined in the course of the decades (millennia?). Tasted OK, but we can do better now.


This page contains (roughly) yesterday's and today's entries. I have a horror of reverse chronological documents, so all my diary entries are chronological. This page normally contains the last two days, but if I fall behind it may contain more. You can find older entries in the archive. Note that I often update a diary entry a day or two after I write it.     Do you have a comment about something I have written? This is a diary, not a “blog”, and there is deliberately no provision for directly adding comments. But I welcome feedback and try to reply to all messages I receive. See the diary overview for more details. If you do send me a message relating to something I have written, please indicate whether you'd prefer me not to mention your name. Otherwise I'll assume that it's OK to do so.
