Ask HN: What do you do?

>I teach an intro programming class each year

God bless you.

Core network technical specialist for a local incumbent telecommunications company; my time is mostly spent managing the multiple (IP/IMS/Mobile/SS7/SDH/DWDM...) networks and integrating new projects into the core infrastructure. Recently also been building some lighter web applications (PHP) for interfacing with the network, so that staff throughout the company can check things without using CLI or complex Java applications supplied by the vendors, saves time for everyone, and makes my job easier :)

Yes I enjoy it, I would much rather be self employed working on my own projects, however as a job until that point it's enjoyable with many different challenges, just still looking for that perfect idea/project :) Also considering freelancing however no clue where to event start, any tips?

Found hacker news through Google, can't remember what I was looking for but the post was fairly interesting, hit the home page and found loads more interesting posts, visited back probably daily since! Found my self no longer browsing other sites like Slashdot, Tech crunch, Lifehacker, as any decent posts on there will probably pop up on here.

I'm a PhD student working in machine learning, on the border of mathematical optimization. I also have a research project about mapping influence and innovation in the history of contemporary music, with ML tools.

I heard about HN from my brother, who's a psychiatrist. I wonder how he got here though.

C, custom drivers.

For storage, PostgreSQL and some custom stuff, also playing with Cassandra. If a web interface is required, SpringMVC - it's not cool but works.
