That's really cool. What resources did you use to learn it?
- kick 7y agoNot the person above, but I'd recommend learning APL first. Arthur Whitney (the author of k and q) got started programming by his father and Ken Iverson (the inventor of APL) being friends, and Iverson giving him live demos of APL. Iverson has a lot of amazing resources for learning J (APL's successor) and APL, and learning it will teach you how to be more productive in q, k, J, APL and more!
- smabie 7y agoIf I remember correctly, Whitney prototyped J in C and only after that did Iverson turn it into a real language.

It likely also formed a draft for A/A+ which Arthur did at Morgan Stanley (open sourced at aplusdev.org, but unmaintained and rotting theese days) - which themselves led to the creation of K.

- smabie 7y agoThe book Q for Mortals is good. It’s available online for free at https://code.kx.com/q4m3/ https://code.kx.com/q4m3/ Also the reference and blog posts are useful: https://code.kx.com/v2/ https://code.kx.com/v2/ It’s not as easy to get information as other languages, but the mailing list is super helpful and all the questions I’ve asked have been replied to by paid Kx (the people that make Q) employees: https://groups.google.com/forum/m/#!forum/personal-kdbplus https://groups.google.com/forum/m/#!forum/personal-kdbplus
