How safe are LiFePo4 batteries these days? Can one use these in -20 to +60 degrees Celcius environments without a fire hazard? I'm asking because I'm creating a similar setup to OP to control the climate in my glider's traile

Begin with the end in mind. This is a good mantra on so many levels. It applies to social relations (don't attack people you'd like to end up friends with), but also to technical matters (consider the entire life cycle of the prod

When things scale in complexity, TDD is the reason why people can move fast. I suggest reading about extreme manufacturing. TDD is not only for software.

There is an exploratory phase before you can make a plan, where you learn by tinkering. Once you have found a solution that works for your context, you can switch to engineering. That's where TDD is used.

Packet capture on Linux has something that I wish I could get in more systems: kernel timestamping. This increases the accuracy of the timestamps a lot, since you lose the context switch to userspace. I wish the same thing was available for

We had an 1040ST, which was later upgraded to 4MB. It also received a DOS chip later on, which allowed us to run DOS software after a reboot. It was equivalent to a 286 I think.

I've had the good fortune to see people use the balance belt, a belt that you can wear if you have bilateral vistibular loss. The tech is simple, but seeing someone go from not being able to walk without leaning against everything to w
