Cleaning up Quicksilver
Given the Quicksilver source code is now out in the open, I’m trying to learn from it while at the same time cleaning it up. Here’s what I’ve done so far.
Another guide to Quicksilver
Joe Dunn is doing a nice series of articles on Quicksilver. He’s covered triggers and scripts so far with more on the way.

I’ve also got a bit more on Quicksilver coming up shortly.
Modifier flags during app launch
Unfortunately, [[NSApp currentEvent] modiferFlags] can’t be used to determine if any modifier keys were held down during launch. To accomplish this, it seems one must delve into the world of Carbon.
Quicksilver Smoke
I wrote this a while back as part of the Quicksilver Internal Commands tutorial. The plugin hooks onto the current Quicksilver interface so you can watch it go up in flames.
CTGradient code bloat
While getting rid of extraneous junk in an application package is easy using Trimmit, the only way to prevent "code bloat" (and accompanying excess RAM and CPU usage) is through good programming practices. Where most developers fall short is in poor optimization of borrowed code. Let’s take CTGradient as an example as it’s well known and used (or more accurately, abused) in dozens of applications.
