In a project I was working on recently, we were building up a web page by loading up its template, content hierarchy and other information dynamically.

New theme for The Simple Part

Karl — Sun, 13 Sep 2009 00:08:41 +0000

Despite my best attempts at procrastination, it had to happen sooner or later. Stephen Reinhardt’s Light theme, the free version of which has served this blog well and faithfully for the last year and something, has finally been decommissioned.

An Up/Down control in jQuery

Karl — Sun, 16 Aug 2009 15:30:15 +0000

iPhone won’t recharge after OS update

Karl — Mon, 06 Jul 2009 00:25:35 +0000

I’ve (belatedly) updated my iPhone 3g’s OS today. Just after the update, it started to heat up, and was not recharging no matter how long it was left on the charger. Restarting (hold down the home and the power buttons simultaneously for about 10s) seems to fix both issues. First law of...

Code reviews with NDepend

Karl — Sun, 05 Apr 2009 11:08:20 +0000

Using NDepend to identify areas of interest in a code base. If you’re working on a project of any size, and unless the entire team is made of uber-developers, code reviews are necessary if you’re going to end up with something that can be maintained. And, the larger the project, the...
