TextMate is, in our opinion, by far the most comprehensive text editor for programming on OS X and we don't know many developers who would use
anything else. It's become the default standard, taking over from where
BBEdit left off.

The 'Find in Project' feature is great, but if you're working on a large project,
which say includes images and videos, searching can crawl to halt, literally
taking minutes to complete within a substantial project. It's more than
annoying but luckily there is a fix.

The default installation of Python on Mac OS X Snow Leopard is version 2.6.1.
It transpires that Python on Snow Leopard executes as a 64-bit application by default.

Daily we use this awesome yet simple Python script, which helps us join any file, for instance a Pages or Numbers document, with a pre-defined PDF template. In our case, this PDF template contains our Letterhead and the script is executed as a PDF Service, showing system wide from the Print dialogue sheet via the PDF button.

For this PDF Service script to work, it needs to use Python as a 32-bit application.
Open a Terminal window and run:

defaults write com.apple.versioner.python Prefer-32-Bit -bool yes
To revert back to 64-bit mode, just change the boolean to “no”, or even delete the “Prefer-32-Bit” key.

Here's a helpful little hint I picked up over at MacWorld: files and folders are hidden out-of-the-box in OS X and this tip makes it easy to show hidden files and folders in Open and Save dialogs windows.

The Hint
In any Open or Save dialog in Snow Leopard only, use the following keyboard combination 'Shift-Command-Period' to show hidden files and folders. Toggle the same keyboard combination to hide hidden files and folders. Nice and simple!
