CPunch

A site about things

I’m CPunch, I write software (for you!) and reverse engineer things. I enjoy being curious, playing the piano and exploring. Wonderful artwork above was made by @hsgrace!

Some all-encompassing highlights:

git.openpunk.com - my self-hosted Gitea instance, most of my projects are mirrored here.
OpenFusion - FusionFall server emulator, relevant post
Laika - Tiny RAT written in Modern C, relevant post
Cosmo - Tiny scripting language, relevant post
Lua VM Manipulation - Manipulating embedded Lua VMs, relevant post

Checkout my blog where I write about my projects mostly, also checkout my journal where I share various thoughts and opinions about things.

Any questions or concerns can be emailed to me at openpunk@protonmail.com. I also have an RSS feed if you’d like to keep tabs on me :)
