[toronto-lisp] Potential new user/dev group for free/open source software
by Rudolf Olah 26 Dec '10

26 Dec '10

I don't know how people feel about free/open source software here, but I've been kinda wanting to start a new group that promotes and encourages the use of free/open source software in Toronto and the GTA and in the rest of Ontario. In terms of Lisp, I guess this would mean discussing the perils and pitfalls of using certain open source licenses for Lisp code or Lisp implementations, and maybe discussing which free software implementations or open source modules are the best to use, and maybe how it impacts business. I think that's one of the larger issues; building a business on free software (I know a few Toronto Lisp people were involved in startups and larger enterprises). So what would you guys think about this? Does anyone here like talking about free/open source software? :P -- Rudolf Olah <omouse(a)gmail.com>

[toronto-lisp] Fwd: [tpm] [Fwd: The Upcoming Dynamic Language Smack Down]

Is anyone defending lisp at this GTALUG meeting? abram -------- Original Message -------- Subject: [tpm] [Fwd: The Upcoming Dynamic Language Smack Down] Date: Thu, 9 Dec 2010 13:33:32 -0500 From: arocker(a)Vex.Net To: Toronto PerlMongers <tpm(a)to.pm.org> I'm going to be representing Perl at a GTALUG meeting (unless someone else wants the job :-)* ). If anyone has any suggestions they would like to make about the points in the notice, please let me know. The meeting notice follows: We are about six days away from the **Dynamic Language Smack Down** at the upcoming GTALUG meeting (14th December, 2010 at 7:30pm). We are going to start things off with a quick five minute introduction to your programming language. We would like you to describe your languages programming syntax by showing us a pre-made demo of code. This is my example <https://gist.github.com/720559>. Then we will have the following panel questions: * How does your language access functionality from C libraries? * How does your language deal with modularization of common functionality? * How does your language handle scalability issues? * Applications that require many concurrent threads of execution? * How does the language interact with threading? * Does it offer other models for managing concurrent processing? * Applications that require loading large volumes of code? * Parsing and compiling can be expensive; is there a precompiled form? * Applications that process huge volumes of data * If your dynamic programming language was not available, which of the other dynamic programming language would you recommend? * What is your languages biggest bug, problem, or limitation you are facing today? * How are you going to solve it? * What's the "sweet spot" for your language? * Where can I find more information about your language? * What kind of community is using and support your language? * What **local** community is using and supporting your language? * What language features are notable and interesting? * What notable applications are using the language? The address of our meeting is: Room GB248, Galbraith Building, University of Toronto 35 St George St Toronto, Ontario M5S 3G8 University of Toronto _______________________________________________ toronto-pm mailing list toronto-pm(a)pm.org http://mail.pm.org/mailman/listinfo/toronto-pm

[toronto-lisp] Pattern Matching in CL
by David Penton 07 Dec '10

07 Dec '10

Do any of you have experience with pattern-matching packages in CL? By this I do not mean only regular expression stuff such as in CL-PPCRE, but rather pattern-matching for function definition as in Haskell, OCaml, the Racket match function, etc. (Although perhaps CL-PPCRE does this also;, but I am only familiar with the string-handling stuff in CL-PPCRE.) My question is: If I want to mimic what is possible in Haskell, ML and kin, etc. what is the best CL stuff for pattern matching? I have looked at CL-MATCH but find the documentation a bit hard to penetrate. I am in a bit of a hurry to get something done that pattern matching would really help, so any recommendations are welcome. Best, - Dave -

Re: [toronto-lisp] Lisp in the AI challenge
by Leo Zovic 02 Dec '10

02 Dec '10

The challenge concluded yesterday, and yeah, Gabor Melis won handily; trouncing the next AI by exactly 200 points. That's significant when you take into account that the typical difference between two consecutive top 100 AIs is between 5 and 20 points. I played around with the starter package too, but didn't have enough time to build a proper contender -Leo Message: 2 > Date: Tue, 30 Nov 2010 00:04:35 -0500 > From: Vish Singh <vishvajitsingh(a)gmail.com> > Subject: [toronto-lisp] Lisp in the Google AI challenge > To: toronto-lisp(a)common-lisp.net > Message-ID: > <AANLkTinm6OhqcqhRZAEtBJ5YmLgu1kz2Yg_=eAgQqz5W(a)mail.gmail.com> > Content-Type: text/plain; charset=ISO-8859-1 > > A formidable Lisp bot, written by a Hungarian programmer, is leading > the rankings by a respectable margin in the latest Google AI > challenge: > http://ai-contest.com/rankings.php > > Let's cheer him on, and hope he stays in 1st place :) > > I found out about this challenge too late and, although I played > around with the Lisp Starter Pack last week, didn't have time to write > a decent bot.
