For simplish parallel runner https://www.gnu.org/software/parallel/ is excellent, can even automate stuff like "copy a file to remote server then run command on it" so you can make simplistic cluster computing with it
FTFY.
It really is absolutely terrible tool as programming language. If your script is more than "a bunch of pipes in a trench coat" just use something else. I'd unironically prefer Perl to it.
Lack of legal system is allowing for all of the problems
I definitely did that once or twice, just send a small craft with some RCS thrusters and reaction wheels then attach it to spacecraft via The Claw
"A directory with a bunch of markdown files" is pretty portable too and there are few apps making that a bit easier.
I do divide "just a random notes" from "cheatsheets I use for stuff I use rarely enough to not remember" but that's about most organization. Just a descriptive title and working search function is enough

Hi XANi! You've successfully authenticated, but GitHub does not provide shell access.> Overnight, all our builds (run on-prem) fail because npm install, pip install etc fail and we spent a long time trying to figure it out. They are still failing to this day and I have to get off the VPN every time I need to run these simple commands. IT absolutely doesn't give a flying ** about developers.
Add their cert to system store ? Won't help inside containers tho... without much fuckery
The car will alert the driver than something is wrong and should stop as soon as it is safe.
Because stopping engine abruptly in middle of highway could be very dangerous.
A lot of cars also have so-called "limp mode" where some failures cause car to limit engine power and other stuff, basically to get to the next point the car can be stopped and towed to shop
edit: https://www.diodes.com/assets/Datasheets/AP3019A.pdf example of simple one. The value of the single resistor decides the max current.
The other problem is that niche high quality stuff also would not benefit from economies of scale as much, and at some point buying 4 of the cheap might get you thru longer than one of the "reliable" one
The top-end electronics are maybe a bad example as (at least till now, it seems to slow down at last) the performance is also a big factor, so buying $700 laptop you will want to replace anyway in few years is sensible over "will never break" $4000 one that will just go out of date.
But on like, just about everything else ? Reliability and repairability please, I will pay extra.
The simplest hardware design is just running it at say 10% max in flashlight mode but allowing for short bursts of overdrive for flashing. The LED is big enough to handle short bursts, but not thermally cooled well enough to work at full power all the time. So you rely on firmware/software to do its job instead of having specialised hardware controller that's only job would be to make sure LED isn't on on 100% for more than say half a sec.
You control software so you don't GAF, but people putting custom one have to take same amount of care
Second example: You're an engineer and need to drive a backlight. You can
* slap a constant-current controller (buck or two of parts) so 100% is a maximum safe level all while regulating it at >90% efficiency * slap a high value resistor costing $0.01 so 100% is maximum level is safe but you lose a lot of power in the resistor * slap a low value resistor then just drive it at 20% duty cycle and waste less heat in resistor all while still costing $0.01
They just most likely picked 3rd. Or picked 1st and misengineered the limits I guess...
Everyone else is free to do with IP, do remixes etc. and if they make something with original IP that is better than originals, so be it ,competition actually working.
Insanely easy to believe. The role of UPS is to prevent data loss when power fails. If something is powered by USB-C it almost always already have its own battery preventing from that.
The only devices that are not are stuff like say, raspberry Pi
Also, there literally are devices like that, just aimed more at stuff like camping, so much bigger battery, usually an inverter on board and solar input.
> Hopefully USB will give us standards for power banks someday so you can get certified ones with a defined form factor and behavior.
If it will be like USB-PD then it will be insanely overcomplicated and nobody will be able to get it right.
You can also practice with purpose and get to a peak of your ability.
