Earlier this week I was working on a project where I wanted to filter a table view based on tags. The data model I was working with was very simple. My table view was bound to an array of objects through an NSArrayController, and each object had it’s own array of NSStrings which represented tags. [...]

I know it’s old, but last week I finally got around to watching Cabel Sasser’s C4[1] presentation.
Earlier this year I gave a talk (my first public presentation ever, actually!) at Johnny Rentzsch’s intimate and engaging C4[1] conference in Chicago. Despite nervousness, it was really great fun. We had just recently finished Coda, and with one [...]

Paul Kim:
Recently, Quentin Carnicelli of Rogue Amoeba asked if there were NSResponder methods that you could hook your “OK” and “Cancel” buttons to to dismiss a modal panel (or sheet). As far as I knew there wasn’t but, gosh darnit, that would be a useful thing to have.

I should have mentioned this a long time ago, but Cocoa programmer Mike Lee has started a charity to save Madagascar lemurs. Prior to reading I had no idea lemurs were in danger of extinction or the good even a small donation could do, but Mike makes some very convincing arguments.
Instapaper is a new web [...]

Great writeup from Daniel Jalkut on examining crash logs with the atos command line tool:
Many developers seem to think that gathering useful crash logs requires shipping a symbol-laden application, but aren’t willing to do so. The fact is, you can have the best of both worlds by shipping a symbol-stripped version of your application, but [...]

One of the changes I made to Runner’s Log recently is a small update to some drawing code to better match the new look and feel of Leopard. Since I’m still supporting OS X 10.4, I had to determine at run time what operating system I’m running under. There are a few ways to do [...]

Mac OS X 10.5 Leopard: the Ars Technica review:
DTrace and Xray invite good questions. “How many files does my application open on launch?” “How many times is a particular function called?” “What does the memory usage of my application look like over time?” DTrace and Xray make the previously daunting task of answering these questions [...]
