Reading code is a skill (2020)

Of course a more accurate statement would be “I disagree with some aspects of what someone on the internet said, even though they have an entirely valid point of view”. But that’s less catchy. I saw a Tweet I violently agreed with, so I…

I wrote a 231-byte Brainfuck compiler by abusing everything
We wrote a Brainfuck compiler back in April . That one developed a simple architecture to support multiple backends. Today, I want to write a new Brainfuck compiler. One that can only run on a single system, OpenBSD /amd64. And one that is as small as I can possibly make it. I broke into the sub-256 bytes club with my…
