Funniest supporting comment on HN version of the article:
“I had a problem with Telecom C back in 1982, so I decided to write a C compiler. Still working on it.” (Walter Bright)

Best on tech side is the DSL example.
Maybe he writes it in assembly…
(Btw: Thanks for posting “best of HN” here. I like it).
