alt Hacker NewsDude, software itself is written in English, not just English but it is most often (but not always) encoded in a character set that is English specific (can't even do French). The docs for every single platform, API and language are in English. You can get translations for some stuff and auto-translate the rest. But you can't even file a bug without English. The people you know probably don't write software, they are probably using computers to scam people and deploy software written by others to aid in that.
Yes the keywords are in English, but that does not mean much. You can not understand them and just use them as magic incantations. The docs often exist in translated versions, and there are also books about the same platform/language so you're not stuck with only the official docs.
