I recently develop a strong urge for programming in #C (again). Despite its shortcomings, it is timeless and has much to offer to the curious programmer. Great new projects are programmed in C and compilers got really good at spotting potential bugs (say hello to -Wall -Wextra -pedantic).
In times of “safe” languages like Go and Rust, it is really fun to get down to the roots of computing with C. Last but not least, the Emacs core is written in C. That’s another strong reason to get my hands dirty again.
