May 2012 - Lightning Talks, featuring Rich Hickey, David Nolen and Kovas Boguta

Demos and Lightning Talks

We are trying something new this month. Rather than one talk, we are opening up the floor for shorter demos and lightning talks (around 20 minutes) that showcase an interesting use of Clojure. If you are interested in presenting a demo or giving a lightening talk, please drop the organizers a note.

#1: Session: a web based REPL

Kovas Boguta (Twitter (https://twitter.com/kovasb) | Github (https://github.com/kovasb))

Session is to the REPL as Light Table is to IDEs. It is a web-based REPL that facilitates the creation, modification, and sharing of active web content, defined in terms of declarative Clojure data structures.

(Fork the source code (https://github.com/kovasb/session) and try it out.)

#2: Optimizing ClojureScript Protocols

#3: Reducers: Clojure's new fold/reduce framework

Rich Hickey (Twitter (https://twitter.com/richhickey) | Github (https://github.com/richhickey))

By adopting an alternative view of collections as reducible, rather than seqable things, we can get a complementary set of fundamental operations that tradeoff laziness for parallelism, while retaining the same high-level, functional programming model. Because the two models retain the same shape, we can easily choose whichever is appropriate for the task at hand.

Getting to and into Google

Make sure you have a first and last name in your profile.

Go to the entrance closer to 15th street near Chase. Tell the guard you are going to Google for the Clojure meetup, he will have a guest list. Go up the elevators north of the security desk (a bank of 8) to the 10th floor. I'll be shuttling people into the room from the elevator, so if you don't see anyone just wait and I'll be out shortly.
