I pretty quickly moved onto building in Win95/98 with MSVC not long after, but I am very grateful to DJ for the compiler and Shawn Hargreaves for Allegro.
I'm sure many others here have similar stories. It was especially valuable to have something like DJGPP back in the mid 90s, when many of us only had access to DOS PCs and compilers were expensive.
Also this title violates the capitalization rule at the very top of the page :)
If you read his about page, "DJ" is his legal name, as-is, with no spaces. It's not an initialism or abbreviation for something else.
Regardless, it's a little weird to criticize someone for how they spell their name. By definition, their name is spelled how they want it. It's a core component of identity.
Not that it is really any of my business, but I wonder if that's always been his legal name, or if he changed it at some point. I can see how if someone is used to going by their initials, they might eventually decide it is more of their real name than their legal name is, and hence change their legal name to match their real one. Conversely, maybe that's actually the name his parents gave him.
OTOH, my mother's real name (what her family and friends call her) and her legal name have always been different. I asked her once if she ever thought of changing it, she told me she's lived her whole life with them being different – she's in her late 70s now – and doesn't see the point of trying to officially align them, the work involved would outweigh any benefit to her
Unrelated fact about Aldrin: his mother's maiden name was Moon. Bit of nominative determinism by proxy there.
