Ask HK: I would like to re-learn C. Any suggestions for a weekend project?

I learned C at my university, but since then I am a backend engineer (golang, nodejs). I would love to get a small weekend project to use C again.

A classic option - some sort of program that processes an RSS feed into legible information. Bonus points if you work out OPML parsing for multiple feeds.

Simple raytracer. Tangible, pleasing results.

[sgundo]

do you have any blog to suggest for an implementation?

If you're interested in the topic there is the aptly-named "Raytracing in one weekend" series of free books:
