Speed Up Firefox web browser – Ubuntu Geek

Ubuntu Geek provides a great little guide on speeding up Firefox. A lot of the about:config settings he proposes changing are already fairly optimal on a Mac, but disabling IPv6 seemed to make the most difference on my case.

FuzzyCom :: Using DTrace for javascript debug on OS X in firefox

Vincent Hellot over at FuzzyCom teaches how to use dtrace to trace javascript problems on a Mac (using a specially compiled Firefox binary for OSX). He hints at being able to do it with Ruby on Rails as well. Haven’t tried this, but can’t wait to do so.

This post aims at introducing the DTrace debugging tool in the scope of a javascript application. It won’t get too deep in the wide field of DTrace functions but I hope it will give you an overview of how DTrace can help to solve performance and debugging issues in your javascript applications

Alan Kay, Computer Literacy and Romance

Found this on my “fortune” program today:

— Alan Kay, “Computer Software”, Scientific American, September 1984

Ruby Appscript – Sweet automation

Yesterday a coworker pointed me to ruby’s appscript. I have found it nothing short of amazing.

I love my Mac, and many of us like the idea of automating our software, until we try to use AppleScript to do it. To say that Applescript is professional developer unfriendly is an understatement. I like ruby but to make ruby and applescript talk requires sending strings to osascript in just the right way and getting the output from osascript back. Not a lot of fun at all.

Enter appscript. Appscript is a ruby library that interfaces with applescript seamlessly.

Quick and stupid: Don't set unlimited on the buffer size of Terminal

If you’re a developer and use Terminal.app, don’t set “unlimited” on the buffer size. After a day of using it heavily to review logs and whatnot your computer will be *really* slow. It’s Terminal.app keeping in RAM what you did yesterday. Stupid and Obvious, but still figured I’d write it down.
