It would be probably in summer, as i'm studying currently, but my knowledge is not very opensource community friendly xDDDDDDD
- Win32-only: Delphi + Win32 API (very well): I love this combination, many well known programs are made with this. I know Visual Basic, but this is not a great thing to tell people of xDDDD
- DOS command-line: Pascal (very well) / C (not so very well)
- POSIX C: not so very well
- Many other useful/useless languages or scripting languages for small things, most of them centered around Win/DOS
...and i usually hate non-IDE (non-RAD) environments where you have to go for 200 tools to edit, to compile, to debug,... welcome to 19th century! It's not that i like modern stupidities based in interpreted languages and virtual slowashell-chines, but i love integrated tools to make you focus in what you should only focus: pro-gram-ming.
Sorry if anyone feels harmed by me, it's only an opinion
