Enable TRIM in OS X 10.7.5 to 10.9.5

Enable TRIM on non-Apple SSDs in OS X

NOTE: This is tested on the versions mentioned in the title, and NOT earlier or later versions. YMMV.

Run the following commands in Terminal…

Backup the original driver:

sudo cp /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage-backup

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Renaming a Django app that has migrations already sucks. This Is a way I found to do it that preserves your old migration history and keeps your contenttypes in order. The trick is, this migration cannot be in the app you are migrating, so stick it in your "core" app or another app you have installed. Just plug in your own old and new app names.
