[toronto-lisp] REMIX THIS GAME (IN LISP!)
by Abram Hindle 19 Jul '10

19 Jul '10

http://dto.github.com/notebook/remix-this-game.html Basically DTO has written a neat game that I demo'd before but you can edit just about everything inside the game. The assets (music, audio, pictures, levels) and even the source code. He's got binaries for many platforms or you can just download the code from github. He also writes: http://lispgamesdev.blogspot.com/ http://dto.github.com/notebook/xong.html abram

[toronto-lisp] meeting Tues. July 6
by Paul Tarvydas 06 Jul '10

06 Jul '10

Who's coming out? Anybody have anything to present, or ask questions about? I know that a number of us are faced with .Net vs. no CL issues. We could continue that discussion. I have a not-fully-tested WAM (Prolog Warren Abstract Machine) written in CL that I could bring, if it interests anyone. pt

[toronto-lisp] Pattern Matching Approaches in CL
by Justin Giancola 02 Jun '10

02 Jun '10

As mentioned at the meeting: * DESTRUCTURING-BIND: http://www.lispworks.com/documentation/lw50/CLHS/Body/m_destru.htm * Chapters 18. Destructuring and 19. A Query Compiler from On Lisp: http://www.paulgraham.com/onlisptext.html or as HTML: http://www.bookshelf.jp/texi/onlisp/onlisp_19.html#SEC117 http://www.bookshelf.jp/texi/onlisp/onlisp_20.html#SEC120 but I find the styling of the latter unbearable.

Are we going to have a lisp meet tomorrow? 6pm LinuxCaffe? I'm good to go, but I don't know about you guys. I have some source code generation stuff that might be presentable by then or maybe we can just discuss something related to it. abram

[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

Hi, everyone! I enjoyed the meeting in November and would love to join again. But since then I moved to Waterloo and what is more I do not have a car. So, I decided to ask everyone here - is there by any chance anyone coming to meetings from Waterloo and who wouldn't mind company of a lisp admirer? Thanks, Nikita
