Is it that amazing how best tools for any given job keep resurging no matter how many times people try to replace them?
Turns out that for many jobs C is simply the best language.
Memory limited? C
CPU limited? C
No OS? C
Need precise-ish control of executed code? C
Want inline assembly you can integrate with? C
New chip/architecture? C
Predictable performance? C
Hm, not surprising after all :)
