sirk390 is the handle I write under. I like tinkering and inventing things, programming, CTF competitions, and science in general — and I write up whatever I end up digging into. Pseudonymous on purpose: the writing should stand on its own, not a name.

what you'll find here

• programming and the things I build;
• CTF competitions and security;
• science, and curiosity-driven rabbit holes;
• bugs, tools, and ideas worth writing down.
