I do high-frequency trading, mostly in C++ and q/kdb+. I am a pro tem moderator of Quant SE. My views are my own and do not reflect the same of my employer.

My favorite answers:

Separating the wheat from the chaff

How much data is needed to validate a trading strategy

Time-series similarity measures

Column-oriented storage for tick data

A new programming language can only succeed if it capitalizes on an emerging frontier
