  • I’ve been an embedded developer for coming up on 20 years at this point, and recently went through a job hunt. Of the three that made it to the offer stage, two used Rust almost exclusively in their embedded stack and one used Rust in their embedded LInux stack and was trying to decide if they were going to use rust in their bare-metal/RTOS stack. I ended up at on of the Rust places, though I had no Rust experience. I have to say, while I do find many parts of the syntax too cute by half, in general I’m pretty happy with it as an embedded language. My current target architectures are ARM Cortex-M7 and Cortex-A53. In general toolchain, and debugger support has been good, peripheral support has been ok but could use improvement.








  • Basically, yes. In the olden days, cell phones sent a ping at least once a minute to the nearest tower, and sometimes more often. The tower would respond with a similar message. There was a 140 character field in the ping that could be used for a variety of diagnostics and network controls. That field was also used for text messaging and so was pretty much free for the providers, other than the very small amount of general network backhaul overhead of sending that message to another phone. Charging for texts was a hell of a rip off.
