Reading a post on some #gemini server's security design[1] reminded me of participating in #hxp #ctf. All of their challenges were completely open-source. The challenge I was solving called "heiko" had a very similar structure. Convincing, but pwnable.

I wonder if vger is also pwnable. Anyway, this post would make a nice high-level #ctf chall.
