real world stuff

i have been known to have the occasional lapse of judgement and make a foray into the real world or do things that real people see. Fortunately, this is rare and the instances can be enumerated.
toronto democamp 5: kids help phone
i presented the modifications made by Yang Luk, Laura MacDougall, Yimei Miao, Andrew Reynolds, and myself on a modified version of JForum for Kids Help Phone at Toronto DemoCamp 5.
toronto democamp 10: pbj - web 0.1
Being inspired by a demo of some web frameworks at Toronto DemoCamp 5, i set about designing a framework that allows developers in different programming languages to write web applications as though they are writing desktop applications. Being somewhat miffed by all the "web 2.0" applications and wanting to bring back the "scruffy" feel of older DemoCamps, i presented my framework, PBJ, at the first Toronto DemoCamp with an available presentation slot.
ddj review of ending spam
While visiting Professor Greg Wilson's office one wintry day, i noticed a book called Ending Spam. i was informed that if i wanted to read that copy, i would have to write a review for Dr. Dobb's Journal. Some days later, i did it. Some of the ideas from spam filtering and the natural language computing course i took in January 2005 eventually made their way into my NSERC project, EDGAR.
headshots: click
Sometimes i grab candids of friends or at events where i'm a photographer.
conferences
Do these even count as forays into the real world? Photos from some conferences i've attended. i may also have a flickr account.

other interests

None.







But don't believe everything you read.

code snippets

Here are code snippets that i've written... more will hopefully appear here over time. It would be appreciated if you dropped me a line if you find any of these useful. i should probably include a disclaimer of some sort lest i be be held responsible for a something unpleasant. So here it is: Use at your own risk and with great power comes great responsibility, so please don't use this code for evil.

Linked List
OCLinkedList is a linked list implementation i put together since one doesn't appear to be part of Cocoa. This should be handy for implementing a queue (e.g. using addObject: and removeFirstObject:). Cocoa already includes NSArray, which is implemented as a circular buffer, but that requires tinkering to get queues of (more or less) unbounded length. Writing a queue providing O(1) operations on the head and tail thus requires a bit more work using only that which is provided with Cocoa. While this implementation is missing many amenities of normal Cocoa collections, it should be sufficient for many purposes. Unlike normal Cocoa collections, this class also supports the addition of nil objects to the list. The testing framework included isn't well documented, though i think it's still reasonably thorough.

NSThread Joining
NSThreadWaiter is a category that extends the functionality of NSThread to include join-like abilities. This may be useful for waiting for worker threads to complete.
