Moving Swap on OS X 10.5 Leopard

By default, OS X 10.5 stores its swapfiles in /private/var/vm:

$ ls -lh /private/var/vm

-rw------T  1 root  wheel    64M May 28 10:32 swapfile0

OS X: To Protect and Serve

Over the weekend an importer force attacked my Mac. Fortunately, even though the box was unattended at the time, Mac OS X retaliated, eliminating all traces of this hostile force.

ImageMagick, MacPorts and MAMP

After installing ImageMagick from MacPorts, I ran into the following error in my MAMP Apache error log when trying to run PHP code that resized images:

Symbol not found: __cg_jpeg_resync_to_restart

To solve this, edit /Applications/MAMP/Library/bin/envvars to read:

DYLD_LIBRARY_PATH="/Applications/MAMP/Library/lib:$DYLD_LIBRARY_PATH"
export DYLD_FALLBACK_LIBRARY_PATH=/Applications/MAMP/Library/lib
