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.

Reminds me of movfuscator [1]. This can compile programs to movs and only movs.

Battelle is great. They also created some software called Cantor Dust [1] that turns files into images to allow humans to easily spot obfuscated data or files.

The sad thing about this kind of work, because I love it, is that to get paid to do it you need clearances and polygraphs and periodic reinvestigations/continuous monitoring and all sorts of things that I find unpleasant.

I'm not sure what you mean but I was a security researcher for a large company for a bit and required none of that. I was required to work airgapped at home, however.

Really? You were doing offensive security work not for a government (/contractor)? What sorts companies, aside from some enterprise pen testers, employ these roles?

Email is in my profile -- happy to clarify/share some very rough details if you'd like.

The tools you’re talking about are not exclusive to offensive security. They’re plenty useful for malware analysis and other reverse engineering tasks.
