Comment Re:Wall Street uses a lot of Perl (Score 1) 496

Actually, it's even better, Wall Street uses tons and tons of the relatively obscure language K (and its related database product KDB or Q). This language looks like so: example xml parser in K (notice that the code is up until the lone "\", then the rest is just documentation).

The code above, and a lot of code like it, is actually used in production work at Wall Street. K actually has a lot of great merits, being a very efficient APL descendant, but it is still kind of fun that Wall Street does use a language far less readable than Perl as a core computation language for a lot of these kinds of models :)
