This month I have increased my Internet link speed from 20 Mb/s down, 5 Mb/s up to 50 Mb/s
down, 20 Mb/s up. It doesn't really seem to make much difference: for most things,
including video downloads, the limiting factor is upstream. Downloads from ARD run at between 184 kB/s (1.5 Mb/s) and 700 kB/s (5.6
Mb/s), while downloads from SRF run at between 1.2
MB/s (9.6 Mb/s) and 2.65 MB/s (21.2 Mb/s). The extra $10 for the higher speed just aren't
worth it, and next month it's back to 25/5.
But today I found a case where it does make a difference, uploading photos to
DigitalOcean:
s3cmd sync /home/grog/public_html/Photos/20150503/big/ s3://lemis/grog/Photos/20150503/big/ -P --delete-removed

Those are speeds between 8 and 12 Mb/s, clearly only attainable with the higher speed. Is
it worth it? Still no, but it's certainly noticeable.
Yvonne over to Julie Donaghy's place this afternoon to check
on Wotan. He's doing well, fortunately.
Then she went to Chris Bahlo's place to feed the horses: Chris herself is at the World Jousting
Championships in Lardner Park.
Catastrophe! One of the young stallions escaped from his pen, damaged various fencing, and
Brana seriously injured her hind leg:
Worst of all, we couldn't budge her from where she was, outside Chris' garage (the photos
above were taken later). The whole issue wasn't helped by problems with
my horrible “smart” phone, but finally we established contact with Chris, who
didn't want a vet; she'll be back tomorrow and will take a look then. But somehow we had to
find a way to get Brana to move. After initial total failure, she gradually did start
moving, and we were able to get her inside.
The whole affair with Brana was made worse by my Android “smart” phone.
I've come to the conclusion that it is next to useless for making phone calls.
The first pain came when trying to contact the vets. Hit a recorded message saying that
they were closed and specifying an emergency number to call. OK, we can do that later.
Hang up. How? Press the ON/OFF button?
Wrong, fool. That doesn't turn it off, but it does get rid of the
correct screen from which you can hang up. So I got the opportunity to test Tim Bishop's
suggestion from yesterday: swipe downwards
from the display at the top. Nope, nothing like a phone display. The recording just kept
repeating, and in the end I found only one solution: power down the phone.
Similar issues occurred when I was on site and talking to Chris. Some popup (“Courtesy
notice: your credit is only $9.98”) obliterated the screen, and I couldn't hang up.
Fortunately Chris did.
This is stupid! What gets me is that neither Tim nor Oliver Musch seem to
have the same issues. Is that good luck or good management on their part? Is the phone app
that came with my Nokia 3 deficient? In
any case, I'm thinking of reverting to my old steam-driven mobile phone: at least I can
always make calls and terminate them without scratching my head. About the only alternative
is to find a saner phone app.
After today's fun and games we didn't feel much like a good meal, but we had the food
prepared, so we did so anyway. Beef skewers, this time lovingly hand-made by Yvonne on the metal skewers that came with the bigger
“air fryer”, the one we call the “hair
dryer”.
Problem: how do you mount them? In the cutouts beside the holes, once again putting them at
an angle:
Next, how long? How hot? Decided on 200° and 15 minutes. But things didn't go well: the
bows of the skewers fouled the edge of the vessel, and I had to reposition the whole thing.
Here's the way it shouldn't be:
I should leave at least 3 cm of the shaft protruding to avoid that kind of problem.
And to make things easier for me, the device continued to turn the rotisserie even when the
lid is open. To stop it I had to power it down, losing all the settings that it makes so
hard to set (long power on, menu, select temperature, +/-, select time, +/-, select
start).
Finally it was done. Probably too long, maybe not hot enough. Next time I'll try 10
minutes at 220°.
Over to Chris Bahlo's place this morning to check on Brana, who seems to have survived well
enough. I hope that Chris is right that she didn't need a vet.
It's been pretty wet lately—we've had more rain so far this month than in January and
February put together—so took a long walk with the dogs today to make up, 3.58 km according to my drunken GPS tracker:
We may live out in the sticks, but this part
of Dereel has been populated for at least
130 years. In 1889 a map was made, possibly
still the most detailed map of the area. Interestingly, it seems that the place was much
more populated at the time. Stones Road didn't exist yet, but this map shows Bliss Road
(running East/West) and Harrisons Road (North/South in the middle of the image). The block
at the top left of the detail,
1000x500 links (about 200x100 m) in
size and marked “S. School", has the beginnings of Stones Road on its East side, and on the
East side of Harrisons Road, just the other side of the unnamed creek (now Spring Creek)
there was a post office.
There's no sign of any construction on the East side of Harrisons Road now; it's just a
sheep paddock. But of course we still use these terms when we walk the dogs.
That's on the corner of Bliss Road. How did it fall over? I don't know, but it had been
like that for a while when I took the photo 3½ months ago. Is a sign even necessary there?
The road is pretty much unused, and Google Maps still claims that both sides are Stones
Road. But yes, they've repaired it, with reinforcements:
So Donald Trump is in
the United Kingdom on a state
visit, one that they clearly couldn't postpone any longer. He's really welcome:
Once again he avoided the streets of London, apparently on advice of his hosts, and landed
his helicopter in Buckingham
Palace. And he made himself popular because of his superb manners, walking ahead of the
Queen to show her the way:
Admittedly, it's worth looking at this in more detail:
I think that Hanlon's Razor
applies here. Not malice, but stupidity.
He applied his malice elsewhere, tweeting insults towards Sadiq Khan, the Lord Mayor of
London, and even misspelling his name in the next blob,
in the process showing his preference for Jews over Muslims:
.@SadiqKhan, who by all accounts has done a terrible job as Mayor of London, has been
foolishly “nasty” to the visiting President of the United States, by far the most
important ally of the United Kingdom. He is a stone cold loser who should focus on crime
in London, not me......
....Kahn reminds me very much of our very dumb and incompetent Mayor of NYC, de Blasio,
who has also done a terrible job - only half his height. In any event, I look forward to
being a great friend to the United Kingdom, and am looking very much forward to my
visit. Landing now!
I've done a lot of travelling in the last few days—just ask Google location services. While
looking for something on the web, I was given a price
in New Zealand dollars and a phone
number to call, also in New Zealand.
And other flowers are doing surprisingly well, notably
the Salvia microphylla (first
image below), which normally doesn't look good at this time of year. But this one looks
better than it ever has done.
The more I look at this issue with the car accident three months ago, the more I wonder
what's going on. We have:
On 12 March the other side got a quote for repairs, for $706.20 including GST.
They did nothing until 10 April, when Bruce called me and told me that the repair would
cost (from memory) $990. I asked him to send me details by email.
On 17 April I got an email with the details of the insurers, only.
On 30 April, after fun
contacting my insurers, I made a report and sent a reply to the other side.
On 15 May, after no reply, I sent a reminder.
On 29
May, still without a response to my email, I got a call from their insurers. On
my request, they sent me the details I had asked for 6 weeks earlier.
The photos in the quote were interesting. Firstly, I had thought that the car had been
white. Why had I not taken photos myself? More importantly, though, was the damage:
I don't recall it being as bad as it looks in the photo, but that could be, at least for the
largest scrape in the middle.
And the other scratches? The one on the extreme right must certainly have been there
before. And it's really hard to see how I could have caused both of the scrapes in the
middle. At the very least I would have had to have had two impacts, which certainly wasn't
the case, and even then it's not clear how one could be that much higher than the other.
So: time to contact RACV. Did that, fought my
way through 2 minutes of menus, and got connected to Laura pretty soon after that. It seems
that they have a preliminary notice from the other side, but not the documents that I have.
But no matter: in all probability they have already approved the payment, in which case
there's nothing I can do, except potentially engage in litigation with the insurer. No way.
I know when I'm beat.
ALDI had a 10.1" Android tablet on offer
today for the attractive price of $100 (or, as they put it, $99.99). OK, that might be an
interesting alternative to my aging car GPS navigator, so I got Yvonne to pick one up for me.
What features does it have? The packaging and minimal instructions are far too polite to
irritate me with technical details. Clearly it doesn't have a phone—it doesn't have a SIM
card slot—and that's almost a reason to reject it anyway. But still, how about trying it
out?
Does it have a GPS receiver? On IRC, Jari Kirma was sure that it would have, but I've had
one from ALDI before that didn't. OK, simple, check the pull-down status page.
Clearly that was too obvious. People need a challenge to find things.
OK, look in the config pages. Nope, nothing there either.
OK, try to install a GPS app. GPS
status seems appropriate. Installed, success! But it didn't show me much in the way
of status. At least it didn't tell me that I didn't have a GPS receiver.
OK, try my old favourite, GPS Logger for
Android. “This app may not be optimized for your device”. What does that mean?
Installed it anyway, and it found my location, though I didn't check on the accuracy. But
how? Despite the name, GPS Logger also
checks Wi-Fi and mobile cell info, neither
of which are very accurate. And how about that, when I disabled that, I didn't get any
fixes any more. Comparing the results on the tablet and taskumatti, I got:
It's not clear why it is requesting cell and “wifi” location updates when they have been
disabled, but it doesn't even try to “request GPS location updates” on the tablet.
It's beginning to look more and more like it doesn't have a GPS receiver. But how do I have
certainty? How about GPS Test?
OK, install and start it up:
What does GNSS mean, and can I rely on it? At the very least I'd expect a clear message
like “no GPS receiver on this device, fool”.
By this time it's fairly clear that the device doesn't have a GPS receiver. But why,
oh why, can't I get a clear statement? Some GPS software works and pretends one is
there, others don't work (just like they often don't work on devices with GPS receivers, for
reasons they're too polite to explain). Why doesn't the configuration screen show what the
device has?
Ah, says Jari Kirma, I can help there. Install (yet another) app, Droid info (and not Droid info, which I accidentally installed on the second device). It produces a report on the
hardware it finds, and in true Android fashion it sends it to my email server in the USA,
because it's too polite to access a file system.
Still, finally I got the information I had been looking for. On taskumatti:
FEATURES
Bluetooth: Yes
Bluetooth LE: Yes
GPS: Yes
NFC: Yes
USB Accessory: Yes
WiFi: Yes
WiFi Direct: Yes
And on the tablet:
FEATURES
Bluetooth: Yes
Bluetooth LE: Yes
GPS: No
NFC: No
USB Accessory: Yes
WiFi: Yes
WiFi Direct: Yes
Only a little over an hour. It seemed much longer.
There's a lot of other interesting stuff to look at in the reports. The one that sticks out
is (on the tablet):
PRIMARY CAMERA
Resolution: 1.9 MP
Flash: No
Video Resolution: null
Supported Resolutions:
Image:
1600x1200
...
Video:
SECONDARY CAMERA
Resolution: 0.3 MP
Video Resolution: null
Supported Resolutions:

640x480
320x240
Video:
If I understand that, it has no video whatsoever, and a resolution that was out of date 10
years ago. What a piece of crap! And it also seems to be slow even by Android standards.
I'll put off analysing more of the output for another day.
Following Donald Trump's tweets yesterday wasn't
easy, especially as Twitter has decided that
it doesn't like my firefox. OK,
there are other alternatives, bringing with them typical silly messages:
Date: Wed, 05 Jun 2019 03:30:29 +0000
From: Twitter <verify@twitter.com>
To: Greg Lehey <twit@lemis.com>
Subject: New login to Twitter from Chrome
We noticed a recent login for your account @Twit.
Device: Chrome
Location: Traralgon, Victoria
*Location is approximate based on the login's IP address.
If this was you
Great! There's nothing else you need to do.
Traralgon is one of the more popular
locations, probably because Aussie
Broadband is located only 12 km from there, close enough for Twitter. But it's 300 km
from here, and the theoretical possibility exists that somebody there is really trying to
crack my account. OK, fool, if you're basing the guess on my IP address, why don't you even
tell me what it is? Sigh.
I've been moaning about the inaccuracy of the GPS receiver in taskumatti, my
current Nokia 3 phone. How about some
comparisons? The new tablet proved to be a non-starter in that respect, since it doesn't have a GPS receiver. But what
about talipon, the old Samsung GT-I9100T? Tried
that out today, with both phones next to each other in my shirt pocket.
The results were surprising but inconclusive. First taskumatti, then talipon:
The first is from taskumatti, and the second from talipon. Both are inaccurate, but talipon surprised me by
giving up in the middle. And inspecting the logs showed that it thought the date was 10
October 1999; it clearly has the 1024 week bug.
And on the way? We stopped on the way to talk to Lorraine Carranza, who happened to be
passing. Again first taskumatti, then talipon:
On careful examination both appear to be equally inaccurate, but talipon looks less
so. Still, there's small choice in rotten apples, even if they're not Apples. Would a
higher-end phone do better? I have my doubts.
So how far did I walk? My guess in advance was about 2.5 km, but taskumatti
suggested 4.08, and talipon (clearly incorrect) still 2.74 km.
On Wednesday I received a new sprinkler relay controller, this time with a housing:
But that was all that came with it. No instructions of any kind! How do I use it? I had
sent a message to the seller and received the reassuring reply:
Sorry for troubles caused to you.
We will contact our supplier for help.
Please kindly wait 2-3 days, thanks.
Don't worry, we will be responsible for this issue.
Tips:1.We need to deal with thousands of emails every day,in case we forget to inform you,kindly please remind us 2 days later,thanks for your understanding!
Tips:2.Could you please do not leave the neutral feedback even negative feedback on our store during this period?it will be bad effect for our store,we know you are a good buyer,right?
In summary: We have no idea, and we might get back to you if we don't forget, but please
don't downvote us.
OK, we've seen this before. What's that chance that the IP address is in the 192.168.0.0/16
address space? That happens so often that I have an alias in my interface configuration:
I really must learn Chinese. But the rest of the document was in rather brief English, and
it showed a whole range of URLs, showing that the programmers only marginally understand
HTTP. The “Port” was a metavariable, not for a port, but for a sub-URL (why?). By default
it's 30000, and the commands are two digits. For example:
1: Default IP: 192.168.1.4 Port: 30000
Open the browser and enter the address bar: http://192.168.1.4/30000 to enter the
control interface.
2: Relay control HTTP command:
Relay 1-8 way command:
http://ip/30000/00 Relay-01 OFF
http://ip/30000/01 Relay-01 ON
http://ip/30000/02 Relay-02 OFF
http://ip/30000/03 Relay-02 ON
And how about that, that worked. There are some other strangenesses, but the biggest issue
that I see now is just installing and testing the device.
Finally! Power feedin configured!

And the content? None. Ah, it's “multipart/alternative”, except that there's no

the Subject: line and the request number. My meter is now configured for power
feedin, only a little more than three weeks after application and 7 weeks after
installation.
But it comes at a good time. Yesterday was sunny, and we generated a record amount of
power:
A while back we bought two enormous jars
of sauerkraut. We do this too often,
but this time I had really planned to make choucroute garni out of them. Today Melanie Bahlo, Chris' sister, was in
town, and Yvonne managed to interest both of them in the
idea, and Yvonne came up with the idea of
a flammekueche as first course.
Somehow my heart wasn't in it. We don't seem to have made it very often: my recipe page
dates from 22 June 2002, and since then I only have records of making
it on 30 March 2003, 3 April 2004 and
29 March 2007—the last time over 12 years ago, before we moved
to Dereel!
Modified the recipe, of course, in the process finding some smoked pork fat dating to the
very first time I made it, 17 years ago! It was deep frozen, of course, and to my surprise
it tasted perfectly good, and there's still some left over. But I made a number of
blunders, and wasn't really happy with the result:
Once again there was the question of the quantity of potatoes. For 1.5 kg of sauerkraut I
wanted 250 g of potatoes. The original recipe wanted 750 g. With Yvonne's encouragement we compromised on 600 g, which I still think is too much.
The flammekueche turned out quite well, but also quite filling:
Walking the dogs to the end of Grassy Gully Road today was not a good idea. Saturdays seem
to have more traffic than during the week, and this time I was passed by no fewer than 12
cars, not all of them considerate, but including Lorraine Carranza and Chris Bahlo, the
latter bearing horses.
What are they? I thought they might be a kind
of Grevillea, and they appear to be
growing wild. Next time I'll come with secateurs and bring some back with me.
Chris Bahlo took some photos of a ride that she, Melanie and Yvonne went on yesterday, on her Samsung SM-G930F phone
(why does Samsung have phone descriptions that have nothing to do with the marketing name?).
They were on Google Drive, another Google
offering that I find hard to navigate. A total of 26 photos and 4 videos. How do I
download them?
Simple: double click with the on the minuscule little fingernail image to the left of a file
name, or on the file name, wait 4 seconds, and you get a popup:
Select Download and it loads the image for you. 28 times and you're done! A good
thing that Chris took so few photos.
Surely there must be an easier way. But how? Google makes it hard to guess. Spent some
time randomly clicking on various parts of the display before hitting pay dirt:
OK, select Download. “Zipping 1
file”. Zipping? These
are JPEG files. They can barely be
compressed.
Ah, says Peter Jeremy on IRC, ZIP is a convenient way of combining multiple input files into
one output file.
Now doesn't that make sense? It spent something like 5 minutes “compressing” the files,
using so much effort that it didn't update the “Zipping 1 file” display until it started the
download.
And how much did it compress? -88%! The archive was 310 MB, while the uncompressed files
took up 165 MB:

Is that really the best that the Microsoft space can do? As Peter Jeremy pointed
out, zip has one other advantage over tar: it has an index of the files. But
that's deliberate in the case of tar, which is designed for sequential access media.
It stands for tape archive, and it's a derivative of ar, which has been around since
before most people in the Microsoft space were born. And of course it has an index.
After processing Chris Bahlo's photos, Yvonne came to me with
a problem: the photos weren't all there when she tried to put them through Ashampoo photo optimizer.
Why? She had processed 24 photos, and there were 24 photos there. No, half were missing.
OK, more checking, and discovered that though there were 24 images, some of the images had
been created from the wrong source image, photos that she had processed earlier. This is in
the convert target, where I convert from the original image in the orig
subdirectory to an image in the main directory. The mapping is described in the
file Makejpeg, where the entries look like:
The first column is the name of the source file (implicitly in orig), the second in
the current directory (implicitly ending in .jpeg), and the third is a rotation
parameter that I no longer use.
The first two images are clearly timestamps, the way Samsung saves its images. The second
two are modified Olympus filenames (the initial 2 is the camera number, which I have
set to easily identify the Olympus cameras we have; 2 is Yvonne'sE-PM2). The next three digits, 608, are an encoding of month (6) and day (08), while
the last 4 digits are a running number. But when I looked at them, Ride-17.jpeg was
a copy of Ride-37.jpeg! How could that happen?
OK, remove everything, convert and optimize. Now Yvonne was
happy. But of course I couldn't resist producing examples of the difference in quality
between the real camera and the phone:
Those are Ride-8 and Ride-9. Clearly you can hold any camera at an angle, but
the image quality and flare reach out and strangle you.
But what do I see?

That's clearly wrong, not once, but at least four times. Firstly, the photo is of Yvonne,
who had her camera on her. From Makejpeg it's clear that it the source file should
have been 20190608_134405_DxO.jpeg, from Chris' camera. The “full frame equivalent”
focal length is clearly not from a Micro Four Thirds system camera. And the location can't come from Yvonne's camera, which doesn't have GPS. Somehow
the Exif data has been mixed up between two
images.
How did it get there? It seems to be a remnant of whatever happened before. The images all
have the correct Exif information, but the
copy that I keep for quick access on the web hasn't been updated.
How do I track that now, after all the shouting's done?
CJ Ellis along today to finish off the stable alterations that he had started a month ago. I thought it would take
him an hour or two, but Yvonne went to help him, and it kept
them both going all afternoon. The result was rather different from what I had understood:
CJ has now received a
new Analogue Telephone
Adapter, a Cisco SPA112, with which he is well pleased. It worked out of the box, and now
people answer the phone much more quickly than before. I tried to explain that the answers
didn't depend on the ATA, but it seems that maybe they did: previously the connection would
drop on occasion, and I don't trust the ring tone to really correspond with a ring at the
other end.
I had suspected the power supply, since I had lent him an alternative, and he hadn't had any
problems with that. My alternative supply only delivers 12 V at 1.5 A, whereas his old
Mitron MV1 (MNFMV1?) needed 12 V at 2 A. He brought back my power supply, the Mitron ATA
and its power supply. 0.4 A! How can that work? But then I checked the ATA again, and
there's no mention of the current requirement. I was sure I saw 2 A somewhere when I lent
him the power supply.
Google searches didn't
help. It seems that the only person ever to use the Mitron was CJ, to go by the hits,
mainly from this diary. OK, I can play around with it and see what I find.
But one of the links was
useful: my diary entry for 13 August 2014, where I noted that the Mitron ATA was almost
identical to the Netcomm V210P. Another search brought me to this particularly emetic
link to the Netcomm V210P User Manual. It, too, was too polite to include specs in
its 56 pages, but the “Package Contents” include:
DC12 volts/0.6 A Power Supply Unit
OK, so the Mitron probably doesn't need 2 A. Is 0.4 A enough, or just scraping through?
What happened there? Clearly some NFS issue, which also
affected eureka:/, the root file system. Force umount, restart mountd
(that was necessary), and all was well again. There were some messages in dmesg,
tripping over themselves.
nfs server nfs server eueureka:/dump: not responding

But they proved to date from 1 May; no further issues. What caused that?
Last week I went to a lot of
trouble to try to decide whether my new tablet had a GPS receiver or not. But after
thinking about it, it occurred to me that I had had issues with OI.Share, which wouldn't install on a device
without a GPS receiver.
Is that still the case? Tried downloading. “This app may not be optimized for your
device”. But it installed, and of course it couldn't find my camera. Take me to
the Settings menu? OK. But it couldn't find that either; presumably the tablet has
hidden the Settings menu somewhere where OI.Share can't find it. I note that it has
hidden the screen shots elsewhere (in fact, in a more logical place, something
like /storage/emulated/0/Screenshots/ instead
of /storage/emulated/0/Pictures/Screenshots/), so maybe it has done the same sort of
thing with the Settings menu? Do I care? Not really. I have long since decided to
return the tablet, and the only thing of interest is the incompatibility from one device to
the next.
It's been a while since I did any serious macro photography, but now
our Schlumbergera is flowering, and
it cries out for focus stacked photos of the flowers.
But how many? Once again, it's just plain guesswork. I set it up with the closest part of
the flower at 25.5 cm from the M.Zuiko
Digital ED 30 mm f/3.5 Macro—once again the optically better M.Zuiko Digital ED 60 mm
f/2.8 Macro was just too long—and erred on the side of caution with 200 shots at
f/5.6. That proved to be correct: it stopped after 57 shots with focus at ∞.
But the shots weren't sharp. Not focus: movement. The exposure proved to be 1/15 s, and
the flowers weren't completely stationary. OK, a case for my Olympus STF-8 macro flash unit.
Frustration on frustration. It's bad enough that the camera (Olympus OM-D E-M1 Mark II)
can't handle focus stacking (“bracketing”) with a monitor connected to the HDMI output, but
I couldn't find any way to get it to take more than a single shot with the flash. It
wasn't until I had given up in disgust that I recalled that I had run into this
problem before. At the time I had guessed that the electronic shutter was
incompatible with TTL flash, though I don't know why that should be. At any rate, it makes
the STF-8 useless for exactly the kind of work for which it is sold. On the other hand,
web
discussions suggest that it should work. What's wrong?
Yvonne off shopping today, as every Wednesday. But this time
there was a difference: not only would the car
(Holden VZ Commodore) not
start, it displayed strange indications in on the dashboard while trying.
Why? In principle the symptoms pointed to a flat battery, but there was no obvious reasons,
and the display on the dashboard (notably indicating the high beam warning light) made no
sense. But yes, the voltage was down to 12.02 V, whereas on my car it was about 12.5 V. So
Yvonne took my car, I put the Holden on charge, and sure enough, it started after a bit of
charging.
So why was the battery flat? No obvious reason (leaving lights on, doors open, etc.). How
old is it, anyway? It seems that we haven't replaced a battery since we bought the car on
23 September 2013, coming on
6 years ago, and there's no reason to believe that the battery was new then. So it's
looking like a change in the not-too-distant future.
Now that we have battery-backed photovoltaic power, I need to set up a cron job to monitor
the grid power to the house: we don't notice any short outages. Today I checked and
found:
Why two “Waiting to connect to grid” messages before “Off-grid”? My guess is that the
inverter is too polite to complain for a couple of seconds until it's really sure that the
grid has gone away. And the total time between the first and last “Waiting to connect” was
63 seconds. On another occasion I had only “Waiting to connect”, and a total time of 61
seconds. So until proof of the contrary, I'll add 3 seconds to the outage times.
And it looks like I won't use it again. I can't get it to power on. Damn, why do I have so
much trouble with flash units? Apart from exposure and compatibility issues, this is the
third unit that has died on me in the last 6 years.
OK, time to look for a new ring flash. I fear, though, that I won't find anything except a
replacement Viltrox.
So I still don't have any good image series of
the Schlumbergera. For the fun of
it, tried stitching the ones I had, with the
unsharp stamens. The results, stitched
with Zerene Stacker were interesting: one
(“PMax”) looked quite good, the other (“Dmap”) was singularly useless:
The “PMax” looked better than I had hoped for, but clearly still not good enough. Still,
the difference between the two methods was amazing. I must read up on the background.
Call from CJ Ellis today. But his name didn't pop up on the phone; instead I saw a number
starting with 09, an internal number used by MyNetFone. And he was complaining that people would call him but just get voice
mail.
OK, he now has two lines. Was the external number (which, I discovered, is called
a Direct inward dial or DID)
attached to the other? Got him to call me on it. No, still a (different, clearly) 09
number.
Config issues with MyNetFone? Found my way into CJ's page on their web site. Yes, now he
has not two, but three numbers, and the DID is attached to his old
Mitron Analogue Telephone
Adapter. OK, they offer the option to change on the web site, so did that. No “submit”
button, just an ominous “Confirmation Code”.
The “Help” didn't, but it's my guess that they want to call the old number to confirm the
change. Fat lot of good that will do with a non-connected and possibly non-functional ATA.
Called up their phone support, got lots of voice suggestions like “Hang in there”
(presumably different from “Hang up”) and “Consider this: (silence)”. Finally, after about
4 minutes, I got the message, first in the confidence-inspiring male voice “currently our
wait times are”, then in a panic-stricken female voice “over an hour!”. I could have asked
for a call back, but it was too late already. Mañana.
One of the issues with my focus stacked photos of
the Schlumbergera is the wear
aspect: how many photos can you take with a flash tube before it dies? It's easy to take a
couple of hundred frames to build a single image. How long would a cheap (or even
expensive) flash unit last under those circumstances?
So how about revisiting LED lights? Did a bit of research on eBay and elsewhere and discovered the Travor RF-550D ring light, a
device without a manufacturer who wants to own up to it. I also haven't been able to find
trustworthy reviews. The Amazon customer reviews are what you might expect: “too bright”; “not bright enough”.
Clearly the first of these were written by people who
haven't RTFM: you can adjust the brightness
down to 1/32, and if the claimed guide number 15 is correct, this would reduce it to 2.7,
which would give f/16 at 17 cm. But I have a sneaking suspicion that the guide number is
specified in feet, which means a real guide number of 4.6, even weaker than the Olympus STF-8, and an issue if you go beyond, say, 50 cm distance.
Still, the price is right: $36, so I ordered one. We'll see if that is any easier to use.
Called up MyNetFone support today to ask
about changing the DID for CJ
Ellis' phone. This time I timed things. 3 whole minutes of various announcements, and then
the confidence-inspiring male voice “currently our wait times are”, then in a stressed
female voice “25 minutes”. So I was able to request a callback, which took another minute,
because they were too polite to assume the number on which I called (one of their numbers),
and then they wanted to read it back to me and get me to confirm.
It didn't help much. They didn't call back, so after a couple of hours I took another look.
Was this confirmation code really for a call back on the old number? I have the
old ATA, so it was
worth plugging it into the network
(behind NAT) and see
if it works. Yes! Tried again, but received no call.
Then I took another look at the configuration display:
That wasn't quite the same as the display. There the number was above
the What is a DID? line. Maybe an Overstamped Caller ID is
something else. Tried “Add DID”, but it told me I had no numbers.
OK, what happens if I remove the DID from the other number? Potentially I lose it. But
basically I had nothing to lose, so did that, added it to the new number, and finally I had:
I've heard a new FLAT (Four Letter Abbreviated Term)
today: DSLM. As I guessed from the context,
it expands to “Digital Single Lens Mirrorless”.
What a stupid term! We already have “MILC”, for “Mirrorless Interchangeable Lens Camera”, a
term that is better but not good: it applies to all
old Leica-like cameras as well,
though that's not the intention: like most digital cameras, they all have electronic
viewfinders. I personally liked “EVIL” (“Electronic Viewer, Interchangeable Lens”), but it
seems that that is too whimsical for certain Christians and people with no humour, though it
does offer the advantage of being expandable to “DEVIL” (D for Digital, of course).
But somehow current terms don't make sense. “Mirrorless” isn't a description of what the
camera has, it's a description of what the camera doesn't have. DSLM has only the marginal
advantage that it sounds like DSLR. But why “single lens”? It would suggest that the lens
is not interchangeable, quite the opposite of the intention.
OK, I'll have to give up on EVIL. But what would make sense? Digital is not important
enough to mention. Single Lens has no meaning any more. Mirrorless is a negative feature.
The things do have electronic viewfinders and interchangeable lenses.
Interchangeable lenses will remain a distinguishing feature; electronic viewfinder won't.
But try as I might, I can't think of a better description than EVIL. Maybe rearrange the
letters? VILE? LIVE? “Lens interchangeable, viewfinder electronic”? None really work.
Maybe retrofit “MILC” to mean “Modern Interchangeable Lens Camera”, then gradually drop the
M?
There's an Arum in front of the laundry, and
it's just coming into flower. But how to photograph it? Clearly I wanted the background
out of focus, something that the “full frame” people think that they have invented. So
clearly I need a wide aperture lens.
The Leica
Summilux 25 mm f/1.4?
Maybe this is one of the few cases where I could do with less depth of field. Before I go
and buy an extreme f/0.95 or even f/0.85 lens, how about longer focal length?
The M.Zuiko
Digital ED 75 mm f/1.8, which I
bought a year
ago and have hardly used? Bingo! Finally a use for the lens:
Mick Solly along again today to finish the mulching. Certainly the garden is looking the
better for it, and finally we have it in a condition that he doesn't need to come every
couple of weeks. Next time early August?
I personally liked “EVIL” (“Electronic Viewer, Interchangeable Lens”), but it seems
that that is too whimsical for Christians and people with no humour, ...
A gentle rebuke on IRC from a Christian participant. Yes, that's valid. I have nothing
against most Christians, just the militant kind who tell me how to live my life.
Like most adherents of other religions, most are good people. Sadly there are too many
people of any religion who use it like a weapon and thus do discredit to their religion.
“ISIL” comes
to mind for the Muslims, but there are certainly too many militant Christians too.
In the case in point I was thinking of the people in the FreeBSD project who decided that the logo was unsuitable,
and changed it. Here before and after.
The punctuation is original. I interpret the first stipulation to include not removing the
indent (which looks silly) nor the size. But then, this is probably the only time I will
use this logo. The second stipulation clearly doesn't include Kirk's emblem, which predates
FreeBSD and doesn't belong to it.
But then, that's only part of the pain. The log
archive is in ZIP format and
has spaces in the path names! What a pain just looking at them! Fortunately nothing
in the conditions prevents me from assigning a sane name. O tempora! O mores!
Clearly little of this has to do with Christians. I've changed the article to read
“certain Christians”.
From time to time I quote web pages, which don't always play nice with the their title. For
example, the NOAA Solar
Calculator has a heading “ESRL Global Monitoring Division”, which doesn't help much.
And when I quote from my diary I get (for example, for this month) “Greg's diary--June
2019”.
That could be easier. Each article in my diary has its own URL fragment (the part after
the # symbol), a coding of the date and time when the article was written. For some
time now they have had their own title, like this one, “More web page mods”. Why not put
that in the window heading?
I had this bright idea of an auxiliary file with an array of fragment (index), title and
topics. Read it in at the beginning of the page, use the fragment to get the title, and
simultaneously build up a new array to write out at the end. That way I wouldn't need to do
anything special to keep it up to date. It would also allow me to create an index for the
page, though with in the order of 100 articles per month it's not clear how that would work
out. I can't think of any use for the topics, but it's cheap and a use might appear.

nvidia.ko! For which, of course, we have no source. Should I even bother to report
it to Nvidia? They'll just ask me to install
the latest version of the driver and try again, I fear. But for some time I've been
pondering the Radeon card that I got a few months
ago and which worked out of the box. A far cry from Nvidia: teevee is down-rev
because the latest version didn't work well with my hardware.
So for the second time in a few weeks, somebody has attacked oil tankers in the area
round the Sea of Oman. Who is to
blame? Iran, of course. Just ask
Donald Trump. They even
have videos to prove it. It seems that the
Iranian Revolutionary Guard
attached a limpet mine and then removed it again when it didn't explode.
Is this plausible? Why should Iran want to antagonize the USA further? If the images
really show the
Iranian Revolutionary Guard,
why didn't they follow them back to where they came from? Why didn't they apprehend them?
Why did the owner of the ship say that it was some kind of projectile? Why didn't the US
soldiers who rescued some of the crew check for damage before leaving?
But no, though it makes no sense, Iran is to blame. I'm reminded of a section in the
OED:
5. to trump up (trans.).
c. To get up or devise in an unscrupulous way; to forge, fabricate, invent.
1695 W. W. Novum Lumen Chirurg. Extinctum 64 His Pouder being..disgraced, he was obliged

Of course, Iran does have some part to play in this matter. It could be more conciliatory.
But looking at the B team, it's not clear that that would help. It's time for the world to
finally take a more neutral view and address these extremists.
It's the beginning of winter, but there are some positive surprises, unfortunately also some
negative ones. On the positive side, some of the native plants are looking very good.
The Alyogyne huegelii that I
planted in the spring, and which gradually developed over the summer, is now in full bloom:
The three plants are in a line, and I've been wondering whether there is something in the
soil that caused the last two to die. Could be just be that, despite everything, there was
just not enough water?
One discovery that suggests that is in the eastern garden:
I think that there was a water leak near the flourishing Hebe, and it also caused the growth
in the “lawn”, really the ground-cover like legume with the small yellow flowers that I've
been trying to cultivate. They're also taking over the central garden bed; I think
that they're the same:
That doesn't seem to be much difference until you look at the dripper line for a scale. But
it's now completely the wrong time of year for it. We'll see what happens in the spring.
One surprise was the Vietnamese mint (Daun laksa). It's flowering!
Nothing overly interesting, but it's very close to a property that we looked at nearly 6
years ago (the same day we first saw our present property), and which we found
uninteresting. I wonder what they're planning to do there.
Yvonne has been wanting to go to
the BallaratMarket, which is only open on Sundays, mainly
to buy Dutch food. I came along with potential interest in even more bulbs, which seem to
be about the only kind of plant that grows reliably in our garden.
The place was almost deserted! In the past, both this hall and the road had stalls on
either side:
Bumped into Julie Donaghy while we were there, and she commented on how much was going on
there. It seems that things were even more deserted a couple of weeks ago.
Yvonne found her Dutch food (mainly sweets) and also some dumplings („Knödel halb und
halb“), despite my protests that we already had some. At least I got a promise from her
that we would soon cook a Sauerbraten
to use some of them.
No bulbs at all! But we did find some other plants:
a Grevillea robusta, growing up
to 30 m high and 20 m wide, an unspecified red-flowering grafted gum,
hopefully Corymbia ficifolia,
two Grevillea
thelemanniana “Covergirl” which claim to be ground cover growing no more than 30 cm
high, and two Grevillea
olivacea x Grevillea
preissii “Sea Spray”. Yvonne wants to plant the last in the spaces left by the
dead Hebes, and I want to put the
Grevillea thelemannianas in the north garden bed next to the existing Grevillea ground
cover. The Grevillea robusta will need careful consideration, probably to the west of the
house where we have space. And the Corymbia? It could fit somewhere in the front yard, but
we'll have to check.
Also another Salvia
microphylla (“Hot lips”), which will probably end up next to the current one, and
a Agonis flexuosa “Westland's
Burgandii” to satisfy Yvonne's love of interestingly coloured foliage. I have no idea where
to put it.
We hadn't brought the dogs with us—Yvonne thought that they might not be allowed in—but that
proves not to be the case:
Another one-second power failure this
morning at 7:17:10 (since installing the photovoltaic system I can get the times exactly).
And of course only discovered by checking my database; even the daily reports are too polite
to mention such things.
I still haven't resolved the Hugin startup bug that
was reported against FreeBSD nearly 2 months
ago. It's puzzling: Hugin crashes on startup with one complaint too many. After the usual
Gtk bitching and moaning, he gets:
(hugin:6057): Gtk-WARNING **: 19:18:30.940: gtk_window_present_with_time() should not be called with 0, or GDK_CURRENT_TIME as a timestamp, the timestamp should instead be gathered at the time the user initiated the request for the window to be shown
zsh: segmentation fault (core dumped) hugin
The problem is, nobody else does. Thomas Modes of the Hugin project says that the
function gtk_window_present_with_time() isn't called from Hugin, but of course it
could be called internally. I've tried various suggestions, none of which seem to help.
Standard installation as far as I can see. Library sensitivities? The only different
libraries are libboost, hardly likely to cause this kind of problem. Incompatibility
between the binary package and his version of FreeBSD? No, he built the package from
source, same problem.
OK, he's running FreeBSD 12, and I'm using 11. Time to install a FreBSD 12 system. That
itself was enough pain to describe separately. But after installation, Hugin ran as expected. No
problems.
What now? Could it be his display hardware or window manager?
Installing a FreeBSD system used to be a
significant undertaking. 21 years ago I did an all-day
tutorial at AUUG 1998 and
didn't even finish installing the base system. No way I want to do that again.
The standard way to install a system used to be to get a DVD image and install from
that. But who uses DVDs any more? USB? While I was looking, I found a
collection of virtual machine images, including one for VirtualBox. Just what I need! Download it and install.
WHAT? The virtual machine image was just big enough for the files that it contained. What
can you do with that? Added a second “disk” for /usr and moved stuff over there,
then tried again:
What's that? Do we really have problems in the packages repository? OK,
mount eureka:/src and build from source. That failed too, with an error that I have
never seen before:
bash: /usr/bin/xargs: cannot execute binary file: Exec format error
Did something go wrong copying /usr to the new “disk”? No, the original one
(/old/usr/bin/xargs) was also broken.
How can that happen? I didn't have time to check, but what I see so far suggests that the
virtual machine images aren't worth the paper they're printed on. Discovered that I already
had a 12-RELEASE DVD image on eureka, so installed from that with no further issues.
So now Yvonne has accepted that we will cook
a Sauerbraten in the near future.
What recipe? I have one, but are there others?
Off to ask Google about Sauerbratenrezept (Sauerbraten recipe). No hits! They were all for „Sauerbraten
Rezept“. People, that's wrong! You don't tear words apart like that! But it seems
to be a case of „Was weißt du denn?“.
Strange how English and German are going in opposite directions in this matter. In English
words get put together, like filesystem and dishwasher, while in German the correct
„Dateisystem“ is increasingly becoming „Datei System“. I haven't seen „Spül Maschine“ yet,
but that's at least because „Spül“ isn't a noun.
And the recipes? Little variation. The one I have wants to have the marinade boiled before
marinating, and the others I have seen don't. But the nicest touch was “Preparation time:
30 minutes”, followed by “After a week, take the meat out of the marinade...”.
Into Ballarat today for yet another
physiotherapy session. Things are looking better, and just as well: it seems that my
medical insurance thinks that it's time to stop paying for my treatment, and today I had to
pay a whopping $5.60 instead of the usual $2.60.
It's been four weeks since Mike Simpson installed the cooktops. The next step is finishing off
the electrical installation, and true to form, I've been dragging my heels.
One more consideration: how much light do we need in the kitchen? And from where? We
bought a light for the other side of the kitchen island (the continuation of the hallway)
months ago:
But now I'm wondering whether I shouldn't put two in. Somehow lighting is particularly
dingy since the advent of LED lighting. So I picked up another one at Bunnings, also looking for strip lighting for below
the overhead cabinets to the left and right of the range hood:
Mail from Harald Arnesen today, referring to yesterday's article on German spelling. It seems that Norwegian is going the same
way as German in this matter, and there's even a web site devoted to this matter. Unfortunately
I discover that my understanding of Norwegian is even worse than I thought, and I can't make
much sense of it. But it seems that meanings change as a result of tearing nouns apart:
“Ananasringer” is a fairly clear word meaning, well, „Ananasringe“ in German: rings of
pineapple fruit. But “Ananas ringer” translates into English as, well, “pineapple rings”
(on the phone). Somehow these problems don't translate well. As usual, Google Translate makes a real cat's breakfast of it:
In the past year, a completely new way of mistreating the Norwegian language has become
more and more common, namely, hyphenation , or special writing as it is actually
called. Words such as dining room turn into eating living room , lamb's leg becomes lame
thighs and cough juice turns into cough juice . We at the AMO believe such language
vandalism should be fought with all legal means, since special writing can make a text
difficult to read, can lead to misunderstandings and is a step closer to an even stronger
assimilation of our language.
Of course, there are other ways to change meanings. German hyphenation rules are very
different from those in English, and a long time ago I learnt an important consequence:
„Urinstinkt“ (basic instinct) hyphenates as „Urin-stinkt“ (“urine stinks”). Other that I
have come across are „Schweinelende“ → „Schwein-elende“ (“pork loin” → “miserable swine”),
and recently „Klößen“ (dative plural of „Klöße“, dumplings), written alternatively (only if
you don't have the right letters to hand) as “Kloessen”. That can hyphenate to „Klo-essen“,
“toilet food”. Admittedly that's incorrect hyphenation, but I've seen it, apparently
unintentional.
We're coming up to the middle of winter, and it is gradually getting cooler, but it's still
quite sunny. And today the “Uncle
Max” Hibiscus
rosa-sinensis in the garden came into flower:
While taking photos of
the Hibiscus
rosa-sinensis, ran into low light conditions. What to do? Trust the image
stabilization (camera and lens together), or set the sensor to higher sensitivity? Why not
both?
That's actually rather disappointing for the image stabilizer. My old rule of thumb from
the 35 mm days was “minimum shutter speed 1/f, where f is the focal length.
This photo was taken at 100 mm focal length, so that would imply a minimum speed without
stabilization of 1/200 s. Modify by 5½ stops of stabilization and you get ¼ or ⅕ s, slower
than this shutter speed. And it wasn't the only attempt at that speed.
Bought some more wine online today, and got the usual confirmation. Well, relatively usual:

It'll be interesting to see what happens, and what recourse I have if the guarantee has to
come into operation.
And that's not on Stones Road: it's on Peppermint Track, which I only know from my
visits to Misery Creek Road. I wonder if I can get through there, and if I'm allowed to.
I've tried “air-fried” chicken skewers a number of times, most recently six weeks ago. On that occasion I decided to do them for 20 minutes at 230° “next
time”.
Interestingly, there wasn't really enough food. The five skewers weighed 450 g together,
which for a steak (150 g for Yvonne, 300 g for me) would have
been more than enough.
Yes, looks like a bus shelter, complete with concrete base and obligatory graffiti. The
problem is, it's on neither road. It can't be that old; have they re-routed the road twice?
Or did there use to be a side track for buses?
So, a number of things to consider relating to focus stacking:
Confirm that I haven't done anything silly with the STF-8last week that prevented focus stacking from working properly.
Assuming that I haven't, check whether focus stacking will work with a flash in manual
mode. I could use the STF-8 for that, but it doesn't have a flash test button, so I
can't measure the exposure!
If that does work in manual mode, go back and try the STF-8 anyway to see whether
it's causing the problem.
Try the RF-550D and see if that works, either in manual mode or in continuous LED mode.
Install the new firmware and try everything again, and also check whether focus stacking
will now work with the monitor attached.
Off to Napoleons to pick the
thing up. Back home, the first disappointment: either there is no way to do a test flash,
or the “test flash” from the button is nothing more than turning on continuous LED not for
the specified 1/100 s flash time, but for about half a second. But the brightness is
nothing like what I'd expect even from a guide number of 15 feet. It's closer to 1.5 m at
ISO 200/24°, or 1.0 at ISO 100/21°.
That might still be useful for some purposes, but if that's the case, the “flash” setting is
useless. But clearly I need preparations before I even try it on a camera.
Yesterday I came within sight of Peppermint Track
in Enfield State Park from the
south. How far down can I get from the north? Tried on the way back
from Napoleons, but didn't
get very far, less than half the distance shown on the map:
Mick Solly, the gardener, along today with a few tons of topsoil to plant our new plants.
We replaced two of the dead Hebes
with the two Grevillea
olivacea x Grevillea
preissii “Sea Spray”:
I had originally intended to put it in the foreground of the first image, but Mick tells me
that the existing blue-flowering salvia is not completely dead, and so there's a good chance
it will return. We'll see.
Finally, planted the Grevillea
robusta to the west of the house, in the “sewage paddock”, not too far from the soakage
for the septic tank. We already have a couple
of Acacia melanoxylon there:
I've already
commented on recipes for Sauerbraten, but
that was mainly about the linguistic aspects. What about the procedure?
„Sauerbraten“ is a typical German
dish—I think. Maybe it's regional, but it seems that most regions have a variant. And that
makes it really difficult to find a typical recipe. Potentially it doesn't matter, but it
would be nice to get something representative.
I have one recipe in my ancient Time-Life cookbook „Die Küche in Deutschland“, a translation
of a 1969 English language book whose title they decline to mention. In general the series
isn't bad, but some of the details puzzled me, so I went looking elsewhere.
What a mess! Once again I came to the conclusion that it's really difficult to find
a good recipe on the web. In the end I came up with this recipe from Chefkoch, which has its own strangenesses (“½ litre
raspberry vinegar, preferably home-made”). And like the other recipe, it wanted the
marinade boiled.
The quantities are always an issue, but in this case they're extreme. Time-Life shows its
origins by using tablespoons and
cups, and it wanted to brown the meat
in fat before marinating, which seemed wrong to me. So I started with the other one—and it,
too, wanted a tablespoon each of salt and sugar. The other quantities were even more
unbalanced:
Time-Life
Chefkoch

1 kg
Wine for marinade
125 ml
750 ml
Vinegar for marinade

Marinade (total)
750 ml
1250 ml
Marinade (per kg meat)
375 ml
1250 ml
Marinate for
2-3 days
3 weeks
I'm sure that the spice quantities are different too, but since they go by count rather than
weight, it's hard to say. In the end I went for the Chefkoch recipe and modified it to my
liking (including considerably more spices) and with a view to consistency.

When the marinade is cool, add the meat and ensure that it's covered by the marinade.
Leave in the fridge for some while.
So now I need to decide how long to marinate it. In principle we're aiming for next
Saturday; 3 weeks really seems excessive.
OK, two questions: why do I need a “supported” browser, and why did I only get this message
today? Off to try on another instance (firefox tries very hard to ensure that I only
run one instance, but it doesn't understand X displays). Oops, wrong password: I hadn't logged in to Google since the repair of
my Nokia 3 phone 4½ months ago, and of course I had changed the password. OK, enter the new password,
log in—no “Unsupported browser” message. Clearly Google has been confused.
That wasn't the end of it, of course. It seems that every time you have a password
failure followed by success, Google tells your phone about it:
That's the entirety of the message. Google, you know how to format emails, and it should be
relatively simple to complete sentences with useful information. Why don't you do it? Why
do I need to go through this rigmarole to find out what it's all about? Not even the HTML
version contains the useful information that gets sent to the phone. Come on, it's not hard
to do it right.
Yesterday's article about the garden plants took up the equivalent of 3 pages of
printout. Why do I go to the bother?
It's not for other readers of this diary, though they're welcome to read it. It's for me,
and today I had—by coincidence—a good reason for it. 14 months ago we planted a bed in front of the “shade area” in the north garden:
What was planted there? In general, I have a reasonable idea, since it's all still there:
the bush at rear left is
an Osteospermum, the one in the
middle lavender, and front right is
Carpobrotus. Only the plant at front
left—a Pelargonium, I think—seems to
have died, strange for a pelargonium. Everything else has grown immensely; if the rest of
the garden did as well I would be really happy.
Only the plant at the rear right is a mystery. It is bigger than any of the other plants,
in fact far too big. Here today:
Clearly it has to go. But what is it? When we planted
it, I didn't even mention what Mick did; I had to look at my weekly house photos to find when it happened.
I have some recollection of a yellow flower, and that we kept it on the south side of the
house before planting. But I can't identify it.
And that's the reason that I write down so many details. This particular incident is
just a coincidence, but I started keeping a diary over 56 years
ago, and again and again I've found that I haven't written enough detail. Some time
during my school time Peter Pears
came to our school and gave a private concert. I was there, mentioned the concert—one of
many—but not the performer.
Interesting article from Statista today: as a
result of climate change, many parts of the US coast are at risk of flooding. The solution:
“seawalls” to protect the coast.
Donald Trump has always
wanted a wall in the south of his country. But why stick to the original concept,
especially since Vicente Fox divulged
a way round the concept: a ladder. Instead, build multiple walls in the sea.
Think of the advantages:
the Democrats
would probably agree to the financing. You can't easily get over them with a ladder. It's
never been done before. If Trump can convince his moron followers that a border wall is
necessary, surely he can convince them that many sea walls are even better, many big,
beautiful walls, the best ever. He just shouldn't mention
“climate change”, or they might no
longer believe.
Walking the dogs takes us through some pleasant countryside. For some reason I have always
found this view particularly pleasant, but I don't know why:
That's a view south-west to the “schoolyard”, where indeed there was a school 130 years ago,
on the corner of Bliss Road and what became Stones Road, at the top left of this section of
the Krausé map:
It's been some
time since I discovered some flowers at the east end of Grassy Gully Road, and I've
been meaning to take
some focus-stacked photos of them
since then; I now have three cuttings in various states of decay.
In the meantime, I have a number of other issues: the problems with my Olympus STF-8 macro flash unit and focus stacking, the failure of my Viltrox JY-670 Macro
Ring Lite, the arrival of the RF-550 “MacroLED Ring Flash” and
the availability of new firmware for my Olympus OM-D E-M1 Mark II.
Today I finally got round to trying out what I had planned to do when the LED “flash” arrived.
In each case, I planned to run a series of 8 images with what Olympus calls “focus
stacking”, in other words with in-camera stacking (straight series for focus stacking are
called “focus bracketing). The first one was with available light. Damn, forgot that the
camera was set for manual exposure, and took a series underexposed by 8.2 EV. Miraculously, DxO PhotoLab managed
to extract something:
Yes, the focus depth isn't enough. One of my pet peeves is that setting the number of steps
is left to guesswork. Clearly I'm going to have to come back and do this photo another time
with more depth of field (100 images?). But it doesn't look that bad.
That's with available light, though. What about with the flash units? First, take
individual test photos with the LED flash, which wants 1/100 s instead of the 1/250 s for
real flash units:
The first was at f/5.6, the second at f/4. Clearly f/4 is better. That's with full power,
subject distance: 6 cm. That corresponds to a guide number of 2.4! And that's at ISO
200/24°. A normalized guide number (ISO 100/21°) would be 1.7! In fact, it seems that the
whole idea of “flash” and shutter speeds is nonsense: the “flash” is no brighter than the
normal LED light. Here “flash” and LED light with the same exposure settings:
So given the camera constraints, I should get double the light at 1/50 s, but the subsequent
photos didn't bear that out. And of course with focus stacking, there are other issues as
well:
Next, try the STF-8. Yes, this time it tells me in its own inimitable way: no TTL flash
with focus stacking! What a useless piece of hardware, especially since it doesn't even
have a flash test button for me to do an exposure measurement. Tried anyway, one stop down
from the “LED flash”:
In the past I have complained about the weakness of the STF-8. It has certainly met its
match. Tried again and again and got good results at 1/16 strength:
So the STF-8 is 5 stops brighter than the “LED flash”. Based on that measurement, and
knowing the guide number of the STF-8 (6.5), the guide number of the “LED flash” is 1.2,
even less than what I calculated from my images above.
But wait, there's more! Next I had to upgrade the camera firmware. Connected up and
started the Olympus
Viewer software, which of course first wanted to upgrade itself. Then connected the
camera and saw a popup. something like “The E-M1 Mark II setting is not supported”. While I
was setting up a screen grab, it reconsidered and let me upgrade the firmware, with the
usual misleading comments.
Try again. There were two things I wanted to check: does focus stacking now work with the
monitor connected, and can I now use TTL flash with focus stacking? In each case, the
answer was “no”. No difference.
What's causing that? My guess was electronic shutter, but no, that still seems to work (and
it limits the shutter speed to 1/50 s, as one would hope). Time for a bug report.
And the RF-550 “flash”? What a useless piece of hardware! Less than one-tenth of the
advertised guide number, applicable in equal proportions to the use of foot guide numbers in
specs otherwise in metres, and just plain lying. Should I return it? It cost almost
nothing, and maybe it could be useful.
It's been a fairly mild winter so far this year, but last night made up for it. The weather
station, 3.5 m off the ground, measured -0.9° at 6:14, but when I got up and went outside,
round 8:30, I found temperatures as low as -3.7° to the south of the house.
And the air conditioner couldn't cope. When I got up the temperature in the lounge room was
round 18°, and the temperature in the office didn't reach 20° until about 10:00. Why?
I've complained about this in the past: it's the ridiculously long time that the air
conditioner rests after de-icing. I've measured up to 14 minutes, and today I counted 13
minutes on one occasion. Now that we have the photovoltaic power installation, I can see
more exactly:
The spikes between 6:00 and 8:19 are where the air conditioner was running. The troughs in
between are where it was de-icing: nearly 50% of the time! Coupled with the reduced
efficiency of the system when it's cold, it's no wonder that it couldn't cope.
And the missing spikes between 7:30 and 8:00? I puzzled about this, but then it was clear:
the system was drawing power from the battery (the sawtooth pattern). Unfortunately the
system doesn't show a total power consumption in this graph.
It almost looks like the tomato sauce or whatever they use in films to depict a murder, and
there are clear car tyre tracks in the liquid. But what is it?
It's clear that I'm no fan of “smart phones”, and I've grumbled at length about “smart TVs”. But now there's a new
source of pain: “smart homes”. I've
read various articles about them, mainly dealing with things like talking to your devices
and remote controlling power points, but mainly the choice of a “system” (clearly
“interoperability” is an old,
worn-out magic word).
It's not as if I don't have various parts of the house connected to my local network. My
article above about the air conditioner is one example, and then there's the network-connected
sprinkler system. But I don't want to be tied to one vendor, and remote control of power
points seems rather pointless to me.
But now there's a new level of pain: smart bedrooms.
What on Earth do you need in your bedroom? The article explains: turn your TV off when you
go to sleep (never mind that we watch TV in the lounge room). More “smart lights”,
ultimately remote-controlled power points, but of course expensive and hard to use:
Smart lights are great for control from the comfort of your bed. You can create timers,
turn them on and off with your voice or phone, and if you use smart bulbs, you can dim the
or change colors to something less harsh for the evening. And with a few routines, you can
create a sunrise effect without having to buy an expensive clock.
With your phone! Instead of pressing on a switch, you swipe your phone a couple of times and you're done!
Or you use voice and wake up your partner. So much more practical. And for only $140 (a
starter kit recommended in a link), you can save the cost of an expensive $10 clock.
But clearly the people who wrote this article live in a different world:
Your bedroom likely has a myriad of electronics, whether that be chargers, fans, heaters,
humidifiers, or TVs. Smart plugs are a great way to give those devices intelligence
without having to buy a new TV or rewire an outlet.
No, my bedroom has none of those items whatsoever. There's a thermostat for the air
conditioner, but that's not interoperable, and it's not part of that list. Dammit, a
bedroom's for sleeping in! What kind of daily rhythm do these people have? Maybe no
lounge room? No partner?
What could I use in the bedroom? About the only thing that I can think of is an
Internet-connected radio and a phone. I suppose the idea of a real phone doesn't occur to
the authors because they only use mobile phones, but they take that as a given, not part of
a “smart bedroom”. Still, when building the house I did have network cabling
installed in the bedrooms, so maybe an Internet-connected radio might not be such a bad
idea. Only there is absolutely no overlap with the “smart bedroom” described in this
article.
Yvonne takes a lot of videos, mainly (perversely) with her
monopod tied to a fencepost rather than using a tripod. And since she's alone, she needs to
cover a wide angle to avoid going off the field of view. In the past I've offered her
my Zuiko
Digital 9-18 mm f/4-5.6 to take the videos, but for some reason she didn't want to do
it.
Today she came and asked me for a wider angle lens than her
standard M.Zuiko
EZ 14-42 mm f/3.5-5.6. What can I offer? Various zooms starting at 12 mm, the 9-18
again, or an 8 mm fisheye? Clearly the fisheye isn't appropriate for video, and the 12+ mm
zooms would probably not be wide enough. So (without reminding her), the 9-18 again.
The results could have been better:
That's completely out of focus! A combination of the
old Four Thirds system lens
and the E-PM2,
which doesn't play nicely with phase-detect autofocus.
What to do? One possibility is to set manual focus, and I went looking for how to do that,
using the designated AEL/AFL button to focus. It seems that you can't in video mode! But I
could use video in normal still mode, and that would work.
Would that be sufficient? I have already got rid of one lens
(the Zuiko
Digital 18-180 mm f/3.5-6.3) because of autofocus problems with the E-PM2. Why not
again? After all, I've had the 9-18 for over
10 years. A Micro Four Thirds 9-18? Or maybe a 7-14? Right now, before the end of the Financial
Year, might be a good time to find one.
Donald Trump is remaining
true to form. He may have held off military strikes
on Iran—prompting some people to see him as
an angel of peace—but now he has put financial sanctions on its supreme
leader, Ayatollah Khomeini
(1902-1989). Better late than never?
This is at round 20 seconds into the clip. Why is it in French? It seems that the
English-language versions have dried up, which makes you wonder about press censorship in
the USA.
It's been (coincidentally) almost exactly a year since I last bought a lens, and then mainly to use up an eBay voucher. Still, it's clear that we need a better
wide-angle lens, so spent a considerable amount of time this morning investigating the
M.Zuiko DIGITAL ED 7-14 mm f/2.8 PRO. Like the other PRO lenses, it's
not cheap. B&H offer it for US
$1,199, corresponding (currently) to AUD 1,713. But we're not done yet: they also want $30
for shipping (admittedly, much cheaper than it used to be), though their calculations are
strange:
DHL Express delivery (4-7 days) for $30.01,
or DHL Express freight (7-10 days) for $212, a little more than 7 times the price for a
significantly slower delivery. And what's this “Duties and Tax”? It should be 10% of the
total price. Ah, it's over $1,000, so there's not
just GST, but
also customs duty. OK, let's accept their $163 as a reasonable (3.3% duty?). That would
more than explain the different sum for the slower and more expensive variant. So at the end
I would be looking at about AUD $2,003.
OK, but that's why I don't buy from the USA. What does eBay have on offer? They're still hard to compare,
because they only sometimes mention GST, and never mention duty. The cheapest I could find
was for $1,239, but from Hong Kong, so really about $1,400, still much cheaper than
the American suppliers.
Can I do better? Years ago I bought from eGlobal, but they closed down in disgust after Australia started charging GST on web
sales. Asked on the and Brenton Schluter came up with an offer of $1184 from CameraPro. Much better!
But then it occurred to me that there's this company DigiDirect, from whom I bought Yvonne'sE-PM2 some years ago, and
with whom I had pain last year. How about that, $1,137.30, and in addition they have free shipping on
orders over $99:
Did that, spoke to Eivind (if I remember correctly), who after some experimentation told me
that I had to press on “Proceed to Checkout”, and then the shipping costs would go away.
And so they did. Next, I had to log in, not helped by the fact that it no longer wanted to
know my password (typically, a comment on what I thought of their web site last time; I
should have been warned).
Reset password, get presented with an almost
illegible CAPTCHA. Wrong, fool! Try
again, get a new password, repeat login. Not only the shipping costs were gone: so was the
item. Empty cart.
OK, try again, and finally it worked. That's really not bad: local Australian stock
with Australian warranty for $1,137.30, more than a third cheaper than the B&H list
price and 43% cheaper than having it sent from the USA. What are the eBay prices like in
the USA? The cheapest that I could find was refurbished for $850 (AUD 1,245), and the
cheapest new one was $1,055 (AUD 1,518). We seem to be much better off here. I wonder if
Donald Trump's trade war has
an effect on that.
While talking to people on Facebook,
discussed my pain with focus
stacking and TTL flash, specifically my little-loved Olympus STF-8 macro flash unit. As always when making claims, I checked them on the camera. Things
were different again:
No flash on camera: all flash modes available.
mecablitz on camera, turned off: only manual selectable.
mecablitz on camera, turned on: all flash modes available.
STF-8 on camera, turned off: only manual selectable.
STF-8 on camera, turned on, RC mode: only manual selectable.
STF-8 on camera, turned on, setting 1/1: only TTL selectable.
Clearly I need to check this stuff again. So I tried another focus stacking row with the
STF-8. Ha ha, only joking. Set the unit to 1/1 and that's what I got: full flash.
Yvonne clearly liked the chicken skewers that we had
last week, and bought some today as well. OK, try at 15 minutes as planned last
time. Here last time and today:
Today I got around to processing yesterday's focus stacked images, 38 of them. Surprise, surprise: Zerene didn't want to know the last 7 of them,
claiming that they didn't belong to the same stack. Here's the last one it accepted and the
first one it didn't:
What's wrong there? Decided that it could be being particularly finicky about some detail
of the image conversion, so put the stack through DxO PhotoLab again
with no changes to the photo gradation, and it worked. The best result was this one (PMax):
I have a reasonably good understanding of microwave ovens. In principle, there's not much
to distinguish them:
Power.
Volume.
Number of power levels.
Distribution of power levels. They should be roughly geometric (each level is a certain
ratio higher than the previous one).
Control: are lower power levels achieved by alternating full power and no power, or can
the oven heat consistently at lower power levels (“inverter” technology)?
There are other marketing buzzwords like defrost (lower power level) and “sensor cooking”,
but in my experience that and others, like guesswork cooking times based on some simplified
view of the foodstuff (“recipes”) are useless.
I receive a daily spam from The Good Guys. Well, not really spam, since I asked for it; it gives me some overview of the market,
and on occasion I might find something worth having, since they frequently have one-day
specials at surprisingly high discounts. OK, this time a couple of “microwaves” (clearly a
term invented by somebody who doesn't know what
a microwave is).
A couple looked mildly interesting. Technical specs? Yes, power level stated. Volume
stated. Pick one:
OK, follow up the links. Lots of technical details (here the SΛmsung):
Colour/Finish:
Black
Capacity:
32 Litre
Wattage:
1500 Watt

Additional Features:

Height (mm):

Now isn't that helpful? I have the volume and the (surprisingly high) power. And that's
all. How many power levels? What magnetron drive technology? And since when is colour and
warranty a technical detail? A good thing I'm not looking for a microwave oven right now.
But wait, there's more. They have a microwave buying guide with some things I've never heard before:
1. Microwave Types
Conventional Microwaves
Converts energy into microwaves that heat the food. Fast and efficient. Comes with pre-set menu functions for ease of use when you are in a hurry.
Convection Microwaves
Also known as microwave ovens because they are a microwave and convection
oven, with a heating element and fan that circulates air around food for faster, more
even cooking.
Provides more variety in cooking, allowing for not only microwaving but also
convection oven baking, browning, crisping and broiling.
OK, catch my breath. There are microwaves and microwave ovens. Microwaves convert
energy into microwaves. Recursively? The latter always have a “convection oven” (as if
any oven worked without convection)? And this convection oven “broils”? What kind of
language is that? The OED has a definition of
“broil”:
To be or to engage in a broil; to contend in a confused struggle, irregular fight or
strife.
Of course it has other definitions too, including cooking with radiant heat (an
Americanism). Where does the radiant heat come from in a “convection oven”?
More to the point, though: it implies that a conventional ”microwave” has the advantage
over the “microwave oven” of being fast and efficient and more convenient when you're in
a hurry.
They do mention one other point:
Some microwaves have inverter technology that delivers a steady stream of consistent
energy into the microwave when you want to cook with a lower heat for perfect pulled
pork, salmon, eggs, sauces and more. Microwaves that don’t have inverter technology have
to switch between using 100 per cent and 0 per cent power when you choose 50 per cent
power, whereas a microwave with inverter technology uses 50 per cent power the entire
time so your food is more evenly defrosted and cooked.
What's pulled pork? Another Americanism. It seems that this new-fangled “inverter”
technology is pretty limited. More to the point, though: how do you find out which
models have the function?
You’ll also need to work out whether you want a benchtop microwave that sits on your
kitchen benchtop and just plugs into your power point (perfect if you’re renting), or,
if you’re renovating or building think about a built-in microwave that’s built into your
kitchen cabinetry and connected by an electrician for a clutter-free benchtop and clean
kitchen lines. A few design-savvy brands have created built-in microwaves that match
their oven, microwave and coffee machines designs for seamless kitchen continuity and
modern style.
In other words, the preferred way is to hard-wire the oven (sorry, “microwave”) so that
you'll need an electrician to remove it if it needs service. What about a power point
behind the oven (sorry, “microwave”)? In practice, I don't know of any microwave oven
that is hard-wired.
Other Clever Ways to Use Your Microwave
Disinfect plastic chopping boards – thoroughly wash, rub with lemon and microwave for
one minute.
Sanitise sponges – submerge non-metal sponges in water with lemon juice or white
vinegar, remove sponge and microwave it for one minute.
Now aren't vinegar and lemon juice good for cleaning!
What a lot of disinformation! It's clear that the text comes from elsewhere, probably the
USA. About the only useful bit of information is the reference to inverter technology,
which, unfortunately, the Good Guys don't think is worth worrying their customers with.
We have planned to take the dogs walking somewhere else than just round the house at least
once a week, though we haven't kept to the plan very well: the last time was over a
month ago.
Today we chose a further
field, Enfield State Park.
That's not far away: we took the dogs there before five years ago, just at the end of Westons Road. But today I thought of a place
where we had been before, right in the middle
of Enfield specifically a place
where we had gone riding 11 years ago.
It may be the middle of winter, but
the Epacris impressa are
flowering:
Interestingly the white variety is here too; I had noted in the past that they're usually at
the western end of the park, and at this end they're red. I wonder if they have been
transplanted.
OK, my ridiculously expensive and hard-to-use Olympus STF-8 macro flash unit has a further deficiency: it doesn't work in TTL mode in conjunction
with Olympus' focus stacking
modes. But others have reported that conventional flashes do. What about my mecablitz 58 AF-2? How about that, it
works! OK, drag out the old ring flash adapter that I stopped using when I got my first
mirrorless camera over 5
years ago and put that on:
And how about that, it worked! Well, sort of. I took one series of 39 shots of my mystery
flower and discovered it wasn't enough. But thinking about it, that's not so bad. The
focus is now set at the end of the focus range, so all I need to do is repeat. And that
worked, almost. After about another 30 shots, the flash overheated, not for the first time.
According to the instructions it should just slow down, but in fact it showed a “low
battery” indication, though the batteries were fully charged at the start. And though they
were quite warm when I removed them to check, they all showed a good level of charge.
So yet another “close but no cigar”. Should I stick with the ring flash adapter? The
reason that I stopped using it was because it's too big for the E-M1: I bought it for the
E-30, a much larger camera.
And how about that, nobody has the adapters for sale any more.
But doesn't this put the STF-8 in perspective? What a useless piece of equipment!
Sigh
OK, that means two new disks: one for teevee and a backup disk on eureka.
Why eureka? Can't I connect it to teevee? Yes, I can, but teevee only
has USB 2, and that's slower than the network.
Yvonne back from town today with two new disks
for teevee, both “8 TB”. Hopefully that will keep us going for a while. Started on
the backup disk, which will take a couple of days to copy the data from the old backup disk.
Aren't modern disks fun? In the early 1980s I could copy a big 300 MB disk in about 8
minutes. Today I copied the equivalent of my first home disk
(a Seagate ST-225 with 20 MB)
in about ¼ second, and the equivalent of the 300 MB disk in about 4 seconds. But it'll
still take 2 days to copy the old backup disk.
Another attempt at focus stacking
the Schlumbergera flowers today.
This time I used the LED light. What a pain! Apart from the difficulty of placing the
camera (with the light shining into my face), I once again had difficulty getting the camera
to actually perform the focus stack operation. Why? Much examination and guesswork. The
shutter should move to “fast electronic shutter” mode, but it didn't. Finally I discovered
the problem: POLA
violation! The camera remembers its position in the (horribly convoluted) menus, a good
thing. When I pressed the MENU button, I got:
Finally got round to cooking my Sauerbraten today. More work deciding what recipe to follow. Some of the ingredients looked
decidedly like the kind of leftover you might have in a German kitchen, such as dried-out
gingerbread and celeriac, both not easy
to find here. In the end I did without celeriac, realizing too late that I could equally
well have used celery: it was just for the flavour, along with its companions onion and
carrot.
I left the gingerbread substitute until it was due in the gravy, with some idea of putting
in the important ingredients for gingerbread. But at the end the sauce tasted good enough
as it was—surprising for what was basically wine and vinegar—so I left it be. The result
wasn't at all bad, and ultimately much less work than I had feared:
The meat tasted very good, almost “melt in your mouth”—I suspect that 2 hours was pretty
much the outer limit for this cut (beef topside). The sauce was also good, especially
considering that it was essentially vinegar and wine.
Finished off our old dumplings (the ones that expired in 2002) in the process. We might
even get to the dumplings that Yvonne bought two weeks
ago before they expire. But it's unlikely: Yvonne didn't check the expiry date
(14 August 2019) before buying them.
It was very wet yesterday—30 mm of rain, much more than the total for the first 2 months of
the year—and there were signs of it everywhere. I wonder how this erosion on Harrisons Road
took place:
The sand is now wet, though the floor around it is not. It looks as if there's a leak
underneath the slab for the verandah. That wouldn't be the first: four
years ago Brett Chiltern made a real mess at the other end of the slab. Is this one
that we all missed? And how serious is it?
Spent much of the day processing photos, both yesterday's focus stacked photos and today's
weekly house photos, postponed because
of the terrible weather yesterday. And I didn't get either finished! But at least the
focus stacked photos are finally showing promise.
