The J Programming Language

There's a lot of cross-pollination between object-oriented and functional languages these days, but there are entire paradigms whose lessons about programming mostly stand apart. APL derivatives contain many insights about factoring, concision, and the benefits of a simple representation, but the broader programming world is largely ignorant those lessons.

In this talk, Tracy Harms (@kaleidic) will give us a gentle introduction to the J programming language. It's terse and cryptic, looking a bit like a cat walked on your keyboard, but that terseness has a reason. The language is elegant, unique, and mind-bending (actually, -exploding is more like it). With Tracy's expert guidance we'll begin to see what this language has to teach.

    A very interesting talk. Gave me some ideas for functional programming in Smalltalk.

    Wonderful presentation - the format was excellent and Tracy conveyed the true flavor of the J language! Now I hope to learn it some day.

    The talk was awesome. I really appreciated the way the speaker started with the basics and gradually built up to more complex and interesting examples. The use of humor and a down-to-earth tone also helped make it engaging and approachable.

    Wish I could be there! This sounds like a great talk. Unfortunately, I'll be at a kid swim meet ...
