I was a long time Gmail user, on the verge of leaving Gmail due to a long list of reasons. This bug was the final straw for me (I know it’s not Gmail’s fault). Got rid of Gmail completely. Haven’t seen this bug since.

I feel fortunate to have chosen embedded software as the career path. 10 years in industry now and never had a dull moment (though I've had some bad colleagues/clients). I work inside a terminal all day, no GUI (even use GDB TUI),

I recommend anyone just starting with bare-metal assembly to get an STM32F0 board and write assembly programs for it. I'm just gonna plug my super small toy RTOS I wrote for Cortex-M0 a while ago. https://github.com/kah

I saw your top comment on this thread. I didn't read the article, but I wonder why MacOS doesn't have the invalidation problem?

Sony WH-1000XM3: I've used several ANC headphones before. None of those come close to this. Sound quality is extremely good too. Good battery life. A 15 minutes charge gives me 5 hours of playback. On the negatives: A bit heavier than

As a side note for people like me who have no option other than C for their safety critical projects, remember there's a MISRA-C standard. If that feels too much, [1] is a good starting point. [1] http://pixelscommander.com&

Trying to figure out the project name. I name my projects no matter how small they are. It somehow makes the project important enough for me to come back to it a few days later.
