To fog up, it has to pass water molecules, which are way larger than gas molecules. I've seen only a few IGUs fog up, all of them had clearly visible damage, and they are ubiquitous here, with many 20+ years old.
And the IGUs themselves aren't very expensive either (unless they're over 1sqm individually), frames indeed are.
My parents redid their home with a dud batch from a company that offered 30 years guarantees. Company was out of business within 10 years and 20 years later ~60% of them are fogged. Still very energy efficient.
EPROM stored codes for controlling video recorder - the card has IR receiver and blaster, you record t-e codes from remote voa receiver, then the card controls the recorder.
It is an EPROM (apparently 8x8KB 2764 in particular), EPROMs are not really intended to be in system (re-)programmed, so storing the IR codes in it does not really make sense. Proximity of pair of ALS193 to that EPROM makes me thing that it contains data for some kind of fixed pattern (by rough approximation the 64kbits work out quite neatly to the horizontal resolution of the "Arvid 1020" text on the spacer pattern shown in the article).
[Edit: alternatively it is possible that the EPROM contains some kind of "microcode" that serves as sequencer for rest of the circuitry, which is probably more likely]
Another interesting things are the 4 wide DIPs at the bottom edge of the card, these are clones of AM29705, which is 16x4bit dual port SRAM, apparently this serves as some kind of minimal buffer between whatever the rest of the card is doing and the DMA activity. As there is no IO except DMA I suspect that the card continually samples input and produces output, probably with the IR input and output being interleaved into the "video" data in some way (as one of the 16 bits?).
As far as I know there is no technological problem for BMW system to have whatever desired rate of adjustability and speed of reaction. It uses planetary gearset with adjuster motor connected to one of the gears - a bot similar to how Toyota Prius's transmission works. So it's more a question of how manufacturer decided it should feel for the user.
Electricity is way cheaper at the poont of generation than for residential consumer.
IIRC, solar now gets to about 3$ per Mwth, so purely energy cost would be about 0.33$ per kg of propane if 100Mj of input energy per kg of propane stands for that electrolyser plus stated 13Mj for Co2 capture for 1 kg of propane.
So, the cost is not negligible, but could be competetive even now, and solar is likely to get cheaper.
Wigig wasn't fast enough to be useful for wireless HDMI, especially given 4k displays arrived right at that moment, and 2nd gen WiGig it's probably way to expensive.
The question is whether it's possible to create a full-rate 224 gbps transciever that is cheap enough to appear in mid range phones, notebooks and TVs and whether it would work without line of sight, but in the same room, with reflected light.
Screens don't provide stereo image nor focus distance the mirrors do, neither the displayed zone changes in response to moving your head.
Afair, reviews of Audi's e-tron's screen mirror were mostly negative and mentioned that it took time to adjust from looking at road to looking at sidemirror screens and back and that you couldn't look "around the corner" with them.
I suppose that true breakthrough would be a development of a plant or fungus "base" that would be able to create animal cells.
So something like bamboo rhizome constantly growing an meat trunk, using either photosynthesis & minerals (plant-based) or plant mush (fungus-based) as source materials.
While I tend to agree, there's obviously jobs where familiarity with stack, tools and best practices is more important than engineering ability.
They may not be interesting, but they do seem to comprise the majority of openly availible jobs.
My current job has minimum emphasis on language (C#, targeting original Framework 2.0, no new features) and zero tech stack. On the one hand it is interesting - not enterprise stuff - and puts the brain to real use often, on the other, I think it doesn't provide anything market worthy to my CV. As most of my collegaues work for over 7 years there, it really seems to be so.
From a perspective of one once desperate for a job, the take-home test resonates the most.
Market and approach to finding a job in IT sector seems to be somewhat different in Russia compared to US, even regarding remote work for non-resident employers, so don't be surprised if something would seem atypical. I'll omit most of the stuff that's not too relevant.
I put an CV on a job site, had few calls, but they were clearly not what I did want. Over the course of about 5 months, I've applied for 3 positions that I could be applicable to - I've never had any experience with web - and that were remote.
On all three I've done take-home tests. The last one took about one week, most of that just thinking, with maybe two evenings of actual coding. They accepted me, and strangely, told me do make a web app, despite no mentions of that in the job description. Luckily, half a year later, I've been offered an non-web, "mainline" position in team.
The one before that didn't go as well. Due to misunderstanging, I've implemented a much more complex solution, and did a mistake in the implementation. Though it was indeed faster than expected solution, after fixing errors.
The first one is what burned me. There were two tests, one done in two hours, and another one was "serious". It used some clearly real data - I had to download it from some US buerau, took a month of 3-4 hours of coding everyday for POC implementation, and not much less than that for a more formalised one, where rule set for matching data entries had to be indexed by 4-D array (not sure if I'm correctly using terminology). I haven't got answer for either version, and only got one a week after an reminding email, when I've asked for some clarification. They've told me they decided to drop the vacancy and not hire someone. Still I don't know whether they just wanted someone to do a task for free, or that it had to be done in a fundamentally different way.
Given that what I'm currently doing isn't market relevant, most likely I won't be any less desperate when looking for a next job.
