It's a distraction. Websites are relatively easy to migrate, Office and AD not so much. Isn't it really a case of measuring what you can see vs what really matters?

Filament implies it is resistively heated, per tube terminology. Nixie is essentially a neon lamp, specially shaped, whose cathode is cold.

> Nixie tube is a tiny electrical tube with filaments in the shapes of all the digits stacked one on top of another, and it displays the desired digit by making just that filament glow

Lol, no. That's a Numitron (although they were 7 segment)

The temperature is independent of the actual heat flux. Also - a quick search suggests that at best the data center coolers run at COP of little more than 10. The inverse of that is the amount of heat wasted just on cooling. Having a system not relying on heat pumps would only make it better. A back of the envelope calculation based on PC AIOs suggests they would achieve a COP of 20 or more. A scaled up system would be more efficient than that, if not just for wider tubes.

I wonder what's the reason. Poland used to have horrible bureaucracy. You could argue this was due to lack of funds, or communist baggage. Yet, over the last decade digital administration has become a norm, rather than exception.

Germany doesn't have such excuses, yet there it is.

I felt this was possible due to slight aliasing you can see on some corrugated structures, but someone has finally done it :) The best part is there's no hallucination or guessing; some have "upscaled" Sentinel-2 data this way and it makes no sense to me.

How about heat? Seems these days it's the heat above everything else that's the issue. And more density would only aggravate it.

Yeah, as I researched the topic of multiple choice exam design, seems the rule of thumb is to reject outright any distractors that are chosen by less than 5% of test takers.

It estimated 74k words for me, but I feel this might be inflated; much of the time when I didn't know the answer - I could vibe guess it just as you did it. The distractor answers weren't convincing enough. For starters, when an answer was based on deconstructing the word into common English words, that ruled it out. After all, if it was, then it wouldn't have been obscure.

A tangent: writing distractors for multiple choice questions is hard. From the exams I know (excluding those whose nature precludes it, such as based on calculation or rote memorization) the only that does this brutally well is LEK (Polish medical graduate exam). It's nigh impossible to vibe guess it at more than random chance for someone outside the field.

The apologetism of American socioeconomic system is a thing endemic to HN. Even Reddit with its USA-skewed demographic is far less delusional, for all its other faults. Same for other social media like YT. I suppose it's a distinction of well-to-do SWEs (and VCs alike) vs actual working class majority.

Then, the dots should be less than 100% opacity, which helps convey density wherever they overlap. It's feasible in overpass turbo with its rather simplistic MapCSS, so it should be possible in proper web mapping libraries.

The HN bubble surfaces mainly those programmers who are either

- active in the startup/VC scene

- "indie hackers"

- chasing platonic elegance with functional languages (for which the world at large doesn't care)

- rewriting everything in Rust

Fabrice doesn't seems to firmly fit any of this.

> The second disadvantage is a lower efficiency than with permanent magnets, which cannot be improved so much as to match PM motors, because the electrical currents that circulate through the rotor windings must generate heat. The lower efficiency also makes cooling more difficult.

Wouldn't the back EMF help here? In brushed DC motor it surely does, reducing losses way below what full voltage over winding resistance would incur.

I was about to recommend a cheap OKI LED color printer (I think C322dn); alas they withdrew from consumer market :/ The colors are super nice and uniform, even if the maximum resolution is only 600 dpi - and the toner won't dry out, which was my brother's crucial purchase criterion; we had HP inkjet clogged more than once.

Moved from Gdynia to Warsaw in pursuit of a job. Left the family and friends, made me lonely. I suppose this is down to particular company culture. I used to work at an American corporation and we often socialized after work. In the new job, while people are as fiendly as there, there's no will to meet up outside the office. Bummer.

And Colorlight i5/9 boards are made for that very application; it just so happens they're a reasonable minimal devboards for ECP5 FPGAs. I don't think right now you can get anything more capable for the price (Yeah, there are super cheap decommissioned miners with Zynq, but there's almost no I/O fanned out.)
