I imagine Paul Graham writes each one for me, and I always enjoy reading them, if only to disagree with them, which is what I did when I read Lies We Tell Kids. In particular, I disagreed with many of the conclusions, or at least the points made along the way toward conclusions, so I http://www.davidbrunton.com/2008/06/long-format-response-to-paul-grahams.htmlnoreply@blogger.com (David)tag:blogger.com,1999:blog-3294480729270581711.post-408137234244008814Wed, 23 Apr 2008 21:27:00 +00002008-04-24T16:00:48.533-05:00artprogrammingprocessingcellular automataThe image to the right was not created using processing.

Like anyone else who spent more than five minutes on the Perl 6 IRC channel, I got a commit bit to Pugs, but Pugs isn't really moving. Perl 6 has some traction on other fronts: Rakudo is moving along at a good clip, Parrot keeps getting cooler, and Perl 5 keeps getting more Perl 6 syntax built in. There are variants of Perl 6 syntax, too:http://www.davidbrunton.com/2008/03/perl-6-is-not-just-language.htmlnoreply@blogger.com (David)tag:blogger.com,1999:blog-3294480729270581711.post-4243784189526177062Tue, 11 Mar 2008 20:31:00 +00002008-03-11T16:52:12.913-05:00Earlier today, a coworker asked me if I thought some people were just destined for mediocrity- to be one of the crowd. Average. Well, my answer is yes. The vast majority of people suck at the vast majority of things. Who cares? I love to bumble along.

I encountered Infinity and the Mind several years ago, wanting to learn a bit more about infinity (duh).

I think Infinity and the Mind is a great book by a phenomenally entertaining and insightful author.

These clarifications occur in three varieties: hacks, optimizations, and refactoring. If the specification of a task changes after the programmer has already completed the programming for the task, there are times when adapting to this change can be done without starting the task.

There are machines, and tasks. The task articulates an abstract need. The machine understands only primitive instructions. Between the two is a great gulf, occupied by the programmer. The programmer builds a bridge over the gulf from both directions. The task must be specified, and the machine's instructions must be abstracted.
