Every developer at some point needs to extract valuable data embedded inside of strings. Jay Fenton has released an extension to kdb+/q on GitHub, which enables Google’s highly optimized re2 library to be used inside of kdb+.

You can find other great kdb+/q GitHub repos at the Kx Github index. If you post kdb+/q code to GitHub, please drop us a note at librarian@kx.com. There are more ways to participate in the Kx Community too, join the Kdb+ Personal Developers Group and look for a Kx Meetup in your area.

Kdb+ Mastermind Challenge

Kdb+ Mastermind Challenge

4 Oct 2017 | , , , , ,

The Kx Community NYC Meetup recently competed in a Mastermind coding competition moderated by expert kdb+ programmer Nick Psaris, author of the book “Q Tips: Fast, Scalable and Maintainable Kdb+.” The top four solutions were notable for the completely different approaches they took. Mastermind is a popular code-breaking game introduced in 1975 that pits a “codemaker” against a “codebreaker.” The “code,” represented by four pegs chosen from a universe of 6 colors, is picked by the “codemaker.” The “codebreaker” continually makes 4-peg guesses and is told by the “codemaker” how many are the correct color in the correct position, and how many are the correct color in the wrong position.
