#openBSD runs servers and computers at #banks and other high-reliability-requirement institutions.

It gave rise to #openSSH and #libreSSL which I believe windows 10 uses to improve your parents' security online.

#ada was #DOD developed for defence application and now runs everything from #missiles to #railway signalling networks to #autopilots

The same is also true for #freeRTOS and #RTEMS which drive rockets into space. There are many #openSource programs involved in rocketry at the highest levels, both civil and martial.

Perhaps most importantly to parents, these are things you can exploit freely, a torch passed to you by others, free as in speech, a tool to better command whatever hardware you elect to use.

I hope you succeed in providing some food for thought about different ways to achieve success ;)

#freertos is really easy to setup, even for a hobby project! I got it running on an STM32 without much pain.

That has been hard work.
Updated a project to #ESP32 #ESP_IDF 5.1.
All went to shit.

Basically #FreeRTOS failing allocs all over - creating tasks or semaphore, etc.

But even modules with PSRAM and over 2MB left are doing it. So has to be a different heap - where and how big?!

Finally managed to revert all to 5.0.1 and working at last.

But this is going to be a bugger to get my head round!

When you can't #sleep so you instead at random start #rewriting the #nfc #library for #flipperzero in a custom #firmware

And yes, all of this will be made public later. :3

Been learning all the things I've forgot about #C over the past decades, doing some #freertos stuff on #esp32 . Actually having fun doing embedded stuff again!

I wonder what are the odds that a commit that has only a message "stability fixes" and modifies the content of FreeRTOS heap allocator to do things differently from the upstream version, really improves stability. (heap_5 specifically if that rings bells)

Sometimes I think that the world would be a safer and a more pleasant place for all if FreeRTOS would only be available as a binary blob.

Hmmm, I'm leaning in favour of using #FreeRTOS for my #rp2040 retro-computer. Go xmodem working so one can now upload "programs" onto the computer. What a hassle it was to get that working! Hopefully "R: tape loading error" are a thing of the past.

#FreeRTOS #esp32

There is a bug in FreeRTOS+POSIX. Some well meaning programmer wanted to safely access the previous value of the counter, but, Atomic_Decrement_u32 decrements what is passed to it before returning it.

FreeRTOS+POSIX doesn't seem to be that used in practice. This worries me.
