[toronto-lisp] Next meeting - April 6
by Vishvajit Singh 06 Apr '10

06 Apr '10

Hello, Our next meeting is a week from now, on Tuesday, April the 6th. Would anyone like to talk about something they find interesting, something they're working on, etc.? I've put together a small program in Clojure to demonstrate Perlin noise, a particular variety of random noise that is commonly used in 3D graphics for generating textures, heightmaps, ocean simulations, and so on. I'd like to show how the program is constructed and I've got a simple graphical demo of 1-dimensional Perlin noise. Nothing too fancy since I haven't gotten into 3D graphics in Clojure yet.. but the math for generating the noise signal is perhaps more interesting. -vish

I'm working on a Scheme compiler in Javascript based on Dybvig's Three Sheme implementations paper. Some things work, others are broken. Maybe we can talk about what works and try to fix what's broken. :) //Sent from iPhone// On 2010-02-27, at 12:00 PM, toronto-lisp-request(a)common-lisp.net wrote: > Send toronto-lisp mailing list submissions to > toronto-lisp(a)common-lisp.net > > To subscribe or unsubscribe via the World Wide Web, visit > http://common-lisp.net/cgi-bin/mailman/listinfo/toronto-lisp > or, via email, send a message with subject or body 'help' to > toronto-lisp-request(a)common-lisp.net > > You can reach the person managing the list at > toronto-lisp-owner(a)common-lisp.net > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of toronto-lisp digest..." > > > Today's Topics: > > 1.

[toronto-lisp] March meeting minutes.
by Vishvajit Singh 11 Mar '10

11 Mar '10

Hi all, I put up what I can remember of the March meeting on our website: http://www.lisptoronto.org/past-meetings/2010-03-meeting (I also put up Abram's notes from February.) Here's that (tongue-in-cheek, but fairly informative) article I mentioned, "Git is MacGyver, Mercurial is James Bond": http://importantshock.wordpress.com/2008/08/07/git-vs-mercurial/ In fact, I've been thinking about MacGyver'ing Git a little.. I'd like a tool that can verify a Git repository, by which I mean go through all the objects in the repo and make sure they still match their SHA1 hashes. That way, if a cosmic ray somehow flips a bit on my hard drive, I can just restore the corrupted object from a backup. It seems like a simple thing, which is why I figure there must be some way to do this already with the tools Git supplies. I found 'git-verify-pack' but that doesn't seem to be quite what I want. Any ideas? If I don't find anything it should be pretty simple to MacGyver a solution, since the filesystem layout of a Git repository makes it pretty easy to iterate through all the objects. - vish

[toronto-lisp] Google AI Challenge winner analyzes his program
by Vishvajit Singh 05 Mar '10

05 Mar '10

At Tuesday's meeting, Abram described his work on the Google AI challenge. Here, the winner of the challenge explains his program in some detail: http://a1k0n.net/blah/archives/2010/03/index.html I remember reading about the Netflix prize, in which winners tended to apply several different algorithms to the problem, selecting between them in different situations, rather than optimizing the hell out of one fundamental algorithm. Seems similar to this case. - vish
