I'm lucky to know a little K. The language basically takes this one idea: instead of processing objects one by one with lambdas and the like, use bulk high-level operations on whole datastructures at once. And really runs with it. For example, it has an SQL DBMS written without loops, using only bulk vector operations.
- prakash 18y agodo you work for a bank? where did you learn K?
- cousin_it 18y agoFound it on the internet and was intrigued. Wrote them an email, got an educational version, read the manual very thoroughly, made up exercises and solved them, read and tried to understand a lot of code. I especially recommend "K finger exercises" http://www.kx.com/technical/contribs/eugene/kidioms.html http://www.kx.com/technical/contribs/eugene/kidioms.html . Then I taught my brother a little - he was into trading at the time, wrote his graduate thesis on time-series analysis and now works at a hedge fund. Also, they recently made q/kdb+ available for download http://www.kx.com/developers/software.php http://www.kx.com/developers/software.php , which turned some of my friends on to it :-)
