It’s difficult to believe we’ve been writing articles for 10 years. In that time I’ve written over 90 technical articles on C, C++ and embedded system design.
To celebrate I’ve picked my ‘Top 10’ articles, with a little background into why I enjoyed writing them so much, or the story behind them.
So, sit back, cue up “At the Sign of the Swinging Cymbal“* and enjoy.

I’m using the word task to mean ‘unit of execution’ or ‘unit of schedulability’, in preference to thread or process. I’m ignoring the different OS memory models.
There seems to be a fair amount of misunderstanding about the concept of priority in concurrent programming:
Priority means one task is more ’important’ than another.
Priority allows one task to […]
