https://news.ycombinator.com/item?id=42742462 was on the front page. We got an email suggesting that the URL should be https://github.com/tomhea/c2fj instead of https://github.com/tomhea/flip-jump. That made sense, except it turned out that github.com/tomhea was banned. That seemed odd because we don't normally ban github domains, so I looked at the history https://news.ycombinator.com/from?site=github.com%2Ftomhea (most of which will only be visible to users who have 'showdead' set to 'yes' in their profile), and it was pretty easy to see that https://news.ycombinator.com/item?id=34856792 was, let's call it, the original sin in this chain of woe. It was also pretty obvious that the other submitting accounts were all related. Since the project itself is interesting I figured the best thing to do was give the submitter a second chance, so

Show HN: Compile C to Not Gates

Hi! I've been working on the flipjump project, a programming language with 1 opcode: flip (invert) a bit, then jump (unconditionally). So a bit-flip followed by more bit-flips. It's effectively a bunch of NOT gates. This language, as poor as it sounds, is RICH. Today I completed my compiler from C to FlipJump. It takes C files, and compiles them into flipjump. I finished testing it all today, and it works! My key interest in this project is to stretch what we know of computing and to prove that anything can be done even with minimal power. I appreciate you reading my announcement, and be happy to answer questions.
