It's the internet-slow time of the month, which is the result of burning through our 25 gigabyte quota. After that, we can have as much 28.8 KBaud data as we can stand. It works well for command line stuff (which is almost everything).
Some websites and applications are non-starters. Slack just gives up out of slowness, but if you reload a few times you can get past the problem and have crappy Slack service.
Email works. Mastodon works, if I turn off automatic image loading in the browser.
I get to install a voltage tap and a shunt in the DC power of the RV this weekend. I have a Bogart Pentametric to use as a joule meter for the PbH2SO4 batteries.
It will log state of charge and energy flow into and out of the new batteries. I have an old RS-232 interface for it, and a display unit on order. I still need a battery temperature sensor.
I'm embarrassingly excited about battery modelling with real-world data. I wish I had the voltages for each of the six battery cells, though.
death in life
The exposures were good!
I got a web preview from thedarkroom.com, where I got the film developed and scanned (no affiliation, just a first-time customer). Through my error, they were scanned at too low a resolution, so I'll have to wait for the negatives to get back before I can see how sharp they are.
Photos taken that day are likely the last of someone who was suddenly and horribly killed. We can't know, but a bicycle helmet or a new inner tube might have saved his life.
I have to do DC wiring today. I've got an old Bogart Pentametric system that I might not have big enough shunts for, and two new 6 volt golf cart batteries, and an old knife switch to rebuild.
I'm sure I should not try to parallel two shunts for higher current capacity. It will certainly change the millivolt/volt ratio of the combined shunt versus a single shunt, and certainly cause other problems.
I can use the data stream to determine if the shunts are damaged by their under-rating,though.
My expectations of what happens after I take pictures with film are formed by the collapse in film manufacturing and local film development and printing, and the digital explosion of imaging, storage, networks, and online businesses.
I found a reputable site that would develop 120 and 135 film, scan it at acceptable resolutions for an added fee, and return what look like contact sheets with the developed film. 4Kx4K scans of 120 are available only by download, not on CD (not DVD, strangely).
The digital spotmeter was a full rout. It required a 6 volt 4lr44 battery, preferably silver oxide (but perhaps not for electrical reasons). I had lr44 batteries, and tried to stack them up to use them, but the geometry of the screw-in endcap shorted the last battery in the stack, and it got hot, and the LED display didn't work.
If it had worked, I would have trusted it completely, and used it to meter the german camera. It's a stable solid-state device: silicon blue cell, integrated circuits.
The old german cameras required different preparation and inspection. No battery, no light meter, so no problem there, but the shutter timing had to be roughly calibrated before use, since leaf shutters are more sensitive to disuse. I earballed them at the one second setting, and disqualified the one that would have overexposed by 40%.
I metered the scene with the old center-weighted SLR, didn't include any sky in the image, set it to F8 and 1/125. The day was overcast, so I am optimistic.
After some directed persuasion, the ring-resistor of the lens and the automatic exposure system in the old camera started communicating through the contacts on the lens mount. The thirty year old LCD displays worked fine, both on the outside of the camera and in the prism, as did the grain-of-wheat incandescent backlight. I didn't have to worry about the shutter speed: the clockworks for the shutter curtains are triggered electrically and accurately.
And then I was taking pictures with film!
Wow. Weird. 400+ pages seems shorter this way. But there they are.

Borges on Nazis
In 1940, Jorge Luis Borges published “Definición de germanófilo” [“Definition of a Germanophile”]:
<< I always discover that my interlocutor idolizes Hitler, not in spite of the high-altitude bombs and the rumbling invasions, the machine guns, the accusations and lies, but because of those acts and instruments. He is delighted by evil and atrocity. The triumph of Germany does not matter to him; he wants the humiliation of England and a satisfying burning of London. He admires Hitler as he once admired his precursors in the criminal underworld of Chicago. The discussion becomes impossible because the offenses I ascribe to Hitler are, for him, wonders and virtues. The apologists of Amigas, Ramirez, Quiroga, Rosas or Urquiza pardon or gloss over their crimes; the defender of Hitler derives a special pleasure from them. The Hitlerist is always a spiteful man, and a secret and sometimes public worshiper of criminal “vivacity” and cruelty. >>

I've been entering FORTRAN from a PDF, as part of a personal project, and the PDF was made from an old paper printout from a teletype.
The OCR from the PDF is worse than useless. It thinks that the page is a single random monkey with a typewriter, interspersed with lots of insects, bird droppings, and twigs.
I'm good with FORTRAN, and there's a lot of redundancy with a document like this (like, named COMMON blocks have to match each other, and line numbers are usually not singletons).
