Most cell OEMs will specify safe discharge (low threshold) voltage in a datasheet. 2.75V is quite common [1]. That being said, system designer might choose higher cut-off point, since: 1) charge/discharge curve is S-shaped. There is ve

My impression is - rust fares a bit better on RAM footprint, and about as badly on disk binary size. It's darn hard to compare apples-to-apples, though - given it's a different language, so everything is a rewrite. One example: Ub

Would that >1000°C reach the surface though? There are some heady boundary-layer effects and temperature/temp-conductivity gradient physics involved here. For simplicity sake, consider a plastic [1] bag full to the brim with water,

Why? Diamond has very low thermal expansion, so no risk of stress/embrittlement/cracks from uneven heating. Or you mean it'll catch fire? Also not a concern. That is supposed to happen at a temperature well above anything use

Yep. And for good measure, first open with O_CREAT as tempfile with random name, then rename() it to predictable "foo.lock".

I use GNU screen for that. Looking at cu , it looks to be just as tiny and has ssh-like tilda-escapes, including "~." to disconnect. Nice, gotta try it out, thanks!

Having too much parameters in your model, so that all of sample/training data is preserved perfectly, is usually considered a bad thing (overfitting). But you're right - if dataset is exhaustive and finite, and model is large enou

Did you "preheat" during those tests? It is very common for cloud instances to have "burstable" vCPUs. That is - after boot (or long idle), you get decent performance for first few minutes, then performance gradually tan

Correct. Also, most 1Gbit/s and faster routers have hardware-accelerated packet forwarding, aka "flow offloading", aka "hardware NAT", where forwarded packets mostly don't touch software at all. Some routers ev

It is possible to write native code for Android using Native Development Kit. Typical NDK use would be to develop a library that is then called into by java code. But one can make whole app with it, 100% java-free: https://github

That's the spirit! :-) By the way, delving into obscure and hardware-specific kernel code, sometimes yields quite interesting generally-applicable problems. For example, @dougg3 did an (excellent!) series of articles about his work on

Gold-plating of contact surface of electric connectors is indeed genuinely useful, on account of preventing contact oxidation. Assuming good contact in connector(s) is achieved, gold-plating does not further help with high-speed signals.

Blind vias, yes. Also - compared to average 4/6-layer PCB - thicker copper layers, thicker metalization of vias, more layers, thicker board overall.
