Last December I solved @synacktiv.com 2025 Winter Challenge: Quinindrome bsky.app/profile/syna... . Here is a 81-byte Linux program which is both a quine (it prints itself when executed) and a palindrome (it is symmetrical)! To learn how I achieved it: github.com/fishilico/sy...
libsodium 1.0.21 was released yesterday 🎉 github.com/jedisct1/lib...
It fixes a small issue I found, showing how hard it is to write C code: github.com/jedisct1/lib... (fixed by github.com/jedisct1/lib... and github.com/jedisct1/lib...)
This summer @synacktiv.com organized an interesting challenge: the aim was to craft a container image as small as possible which replicated itself (i.e. an OCI Image Quine), bsky.app/profile/syna....
I am now publishing a write-up of what I did (Rust/asm/code golfing/...): github.com/fishilico/sy...
After finishing in the top 3 of ZK Hack V competition, I got interviewed with the two other winners. The replay is available on www.youtube.com/watch?v=gLy0...
The competition consisted in solving 3 puzzles involving vulnerabilities in Zero-Knowledge systems. More details on zkhack.dev/zkhackV/
