ITP Winter Show 2009

Sunday, December 20th, 2009

photoThe 2009 ITP Winter Show is Sunday and Monday, December 20–21. The first visualization of my ongoing bicycle data logging project is on display under the title “seismi{c}ycling“.

This visualization traces the routes I rode throughout the fall, highlighting big bumps. Areas of New York which caused me to experience lots of bumps begin to glow bright red.

The show is a great time; I’d highly suggest coming to see the myriad of projects this year. There’s a online guest book with project map at ITPGuestbook.

i finally got around to building a proof of concept implementation of tesseract-ocr for the iPhone. months ago, i documented the steps which helped to get the library cross-compiled for the iPhone’s ARM processor, and how to build a fat library for use with the simulator as well. several folks have helped immensely in noting how to actually run the engine in obj-c++. thanks to everyone who has commented so far.

Moderators are chosen from among the registered users using a somewhat obscure algorithm which incorporates each user’s karma rating (a scale of Terrible, Bad, Neutral, Positive, Good, and Excellent), length of membership and randomness. Selected moderators are given special status and 5 mod{eration} points with an expiration window of three days. The moderation status ends when the points have been used in the act of moderating comments or have expired.

The moderation system has been borne out of necessity as the Slashdot community has grown large, bringing the signal-to-noise ratio down and decreasing the satisfaction in reading the raw comment threads. “Flamebait” and “trolls” contribute little more than instigation for starting arguments and fights among the users with typically strong opinions on matters which usually appear on Slashdot. Rob Malda, founder of Slashdot, explains this phenomenon on the Slashdot FAQ: (more…)
