We're actually using Clojure at work + Lambda calculus

Originally this meetup was going to have one presentation, but we got an offer we couldn't refuse - using lambdas (and lambda calculus) to implement true, false, arithmetic and other fun stuff. So there'll be a grand total of two talks, yay!

We're actually using Clojure at work (~1h)

Kodemaker is making their first product. On the tech side, it's essentially a collection of webapps with a Clojure backend and a single page web app frontend.

August Lilleaas will show and tell, and demonstrate the how and the why of the Clojure side. It's a pretty large and intricate system, with some interesting takes on functional programming (global singletons, ewww). There are a few open source components made as a side effect of the work as well, these will be explained and demoed.

The Computas Lambda Club presents: Lambda calculus (~45m)

If you are as obsessed with purity as US teenagers wearing chastity rings, or if you have a less-than-healthy interest in the obscure parts of functional programming, then this is the talk for you. It is probably useful with some basic knowledge of a LISP, but basically all we need is lambda, so all you should need to know about is lambda...

Jonas Winje will enlighten us on the purest of the purest, the lambda calculus. Starting with just lambdas, and guided by questions from Einar Høst, Jonas will define the basics of a programming language. Live-coding will be the tool, in Racket and in Jonas' own Sublime Text 2 plugin that does tricks on lambda expressions.

    Jonas Winje has written a plugin to Sublime Text 2 that does beta-reductions and stuff on lambda calculus expressions. If there are room for more presentations, maybe I could talk him into presenting it. It is obviously extremely pointless, but he did manage to teach me and another girl at work lambda calculus from zero previous knowledge to writing small programs with only lambdas.

    Great to see Clojure used in practice, thank you for sharing!

    We just booked Scotsman, 2nd floor. A bit overkill, but at least we'll no doubt have room for everyone and then some.

      To continue the discussion - I've booked a table at Amundsen from 20:00 for 16 pax (was the max I was allowed to). I said about half might dine as well. Please book more if you know a bunch more going! :)

    We'll probably have room for more than 80 people but I'm awaiting a final confirmation of which venue we will use before I update the number of spots available.

    Just updated number of spots to 50, hopefully we'll find a venue big enough to fit all of the RSVP-ers.

      Let me know if you can't find anything, maybe we could host it at Lysaker. I would have to check if the largest room is available, though,. Guess it would be better to run it downtown somewhere, but let me know if you can't find anything.
