BeeOS
A simple, minimal "Unix-like" kernel trying to be POSIX compliant.
(at least with regard to the implemented services).
The kernel is **NOT STABLE** and is a discontinuous work mainly used as a didactical tool for operating systems and low level programming.
Because of it's simplicity it can be used as a trampoline to start digging with common operating system problems.
Once you've mastered the BeeOS sources it will be a lot easier to start hacking with more complex OS projects

BeeOS kernel
Re: BeeOS kernel
Just released a new kernel version (v0.2.0)
The kernel has been subject to a major code refactory and an in-depth static analysis using the following coding standards:
- SEI CERT C
- MISRA C 2012
- MISRA C 2004
The kernel intensions are not to achieve full compliance (a lot of violations still exists).
The purposes are didactical, an opportunity for code refactory and dead code removal.
If you are interested in coding standards take a look at the full analysis document https://datawok.net/articles/2018/beeos_static
