What was I last working on? I remember writing a note to help me remember... You can download the challenge files here:

- The chall is called time machine and we're given a git repo. We're just supposed to "wind back time" (check out an older commit) and get the flag. We could just use this classical oneliner though:
git grep -n "picoCTF{" $(git rev-list --all)- Uh, wait, no... I was completely wrong, the flag was just in the commit name...
git log --oneline | grep -Po "picoCTF{.*}"
Flag: picoCTF{t1m3m@ch1n3_d3161c0f}
