Deadline approaching: in the Find the People, Lisp Programming Contest

pat — Thu, 02 Sep 2010 01:02:53 +0000

If you haven’t started your entry for the TC Lisper’s Programming Contest, you’re not too late. The deadline is September 19th.

If you have started, post a comment here or there to let us know how it’s going!

Find the People: Lisp Programming Contest sponsored by TC Lispers

pat — Sun, 01 Aug 2010 00:27:32 +0000

Your Lisp program will be given two input images from the same web cam. The first image will contain zero people, the second image will contain at least one person.

Your program’s goal is to find the people. You will get points for emitting the pixel coordinates of a pixel inside a person. You’ll get bonus points if it’s a head pixel. Be careful, though. You’ll lose points for emitting more than one pixel per person.

Deadline: September 19th.
Target Platform: SBCL or Clozure under Mac OS X (10.6.4).
Prizes for: Tournament winner, Prettiest code

Apology: Unfortunately, ScreenFlow bombed out on me when I went to stop recording. It subsequently saw that it had a partial project there but was unable to recover it. As such, there is no video available for this presentation. Feh. — Patrick

TC Lispers Meeting — July 14th, 2009

The second TC Lispers Meeting will be July 14th from 6:00pm to 8:00pm. It will be at the Common Roots Cafe on 26th and Lyndale.

TCLispers.org Up and Running

pat — Mon, 15 Jun 2009 14:09:02 +0000

Just put up a little bit of a website for the Twin Cities Lisp User’s Group at tclispers.org. Right now, it’s light on content. I don’t expect it to be particularly high-volume. It should at least start accruing slides from meetings as we get more of those under our belts.

First TC Lispers Meeting A Success

pat — Fri, 12 Jun 2009 15:08:27 +0000

The first meeting of the TC Lispers group was a big success, IMO. I was figuring on an attendance near 20. My estimate is that it was really right around 40. That left us a little cramped in the meeting room at the Cafe, but we managed. We also lost the room before the presentation portion of the meeting was completely done, so there wasn’t much time for mingling. Actually, there was apparently a patio where people mingled afterward. I didn’t see this and took off too early. Mea culpa.

The presentation at this first meeting was on NST (not an abbreviation or acronym, but a sound effect /unsst/) which is a testing framework for Common Lisp. John Maraist did the presentation. He was a lively presenter, definitely had a good grasp on some dark corners of Lisp (like exactly what’s involved in the underbelly of MOP). Being a Haskell hacker though, he had some strange opinion that Lisp would be better if only it had strong typing. Well, what can you do? I mean, it’s not like he kicks puppies, I suppose. 8^)

It was great to see so many Lispers at so many levels there. About six or seven folks worked at Honeywell at some point in the past. Apparently, Honeywell had lots of Lisp development at one point. Who knew? About six or seven folks (overlapping a bit with the previous group) currently work at SIFT. There were some University students, a University teacher, some Ruby folks who wanted to see what Lisp was all about, some Lisp hobbyists, some independent consultants, some folks who can get Lisp in under the radar in their jobs, and on and on.

The next meeting is going to be 6pm on Tuesday, July 14th at the Common Roots cafe on 26th and Lyndale in Minneapolis. The topic is not quite set yet, but it seems like it might be a series of short talks on introductory aspects of Lisp.

There’s much discussion going on on the mailing list about finding a bigger venue for August and onward. There’s much discussion about exact topics for next month’s meeting. If you’re able to make it to the Twin Cities on a Tuesday evening, mark your calendars and come on out.
