#2I was curious what kind of company needed to develop all these different kinds of advanced tech. Turns out it's just so they can be sneaky and trade shares quickly. Kind of sad IMO.

#3I've not heard of Jane Street, but looking at the site, it seems they're quite the tech-savvy group for an _asset trading_ company. And reading the article, they apparently "trade" (pun intended) in quite a few different things from CSS to OCaml, which is really nice to see for a place that doesn't directly deal with software as their [business] product (or did I misunderstand their market?).

#4How many of these projects are actually merged to master and live though? I noticed the phrase "worked on" a lot, as opposed to shipped.

One of my favorite experiences was that as an intern I shipped what I thought was a useful tool. When I came back full time a year later it had spread and was pretty popular among a subset of the company!

If you want to learn about Jane Street:
1. Watch Stand-Up Maths and Numberphile videos on YouTube and do not skip the sponsor advertisement readings, e.g. https://youtube.com/watch?v=eqyuQZHfNPQ .

Can someone who actually understands the topic explain to me (or link good resources) why/if what they do is useful to anyone?
Or are they literally just in the business of making money?
(anyone except themselves of course. I'm serious, any hints of irony are unintended)

They are basically the main company driving OCaml development outside INRIA, and the main authors behind Real World Ocaml book (https://dev.realworldocaml.org), which followed up a similar one for Haskell.

Part of Jane Street's business is HFT, and software is the "product" of HFT firms, because without extremely low-latency software (and hardware) they cannot make money.
