Claude Code deleted my project so I built claude-file-recovery, a CLI-tool and TUI that is able to extract your files from your ~/.claude session history. I hope you'll never need it. github.com/hjtenklooster/cla…

Proud to be part of the @Deloitte #UnlockTheCity badge app team that is working on this great game. Mad probs to my colleagues who do the heavy code lifting! And thanks to Narwal for the great artwork and design.
#HackyHolidays goes to #MCH2022 this year! You'll be able to play the CTF in our village and we're building a great game for the conference badge. We need your help to regain control of the city. Play unlock the city on the @BadgeteamNL badge.
