redis auto start OS X

Install with Homebrew

brew install redis

Set up launchctl to auto start redis

$ ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents

/usr/local/opt/redis/ is a symlink to /usr/local/Cellar/redis/x.y.z (e.g., 2.8.7)

Converting MySQL4 database dump syntax to MySQL5
#
# MIGRATE MySQL4 DATABASES TO MySQL5 - Steps for dumping and converting
#
# Uses mysqldump and patches output to be compatible with MySQL 5.5+ (? - no sure
# at which specific release of MySQL 5 the old style syntax support ended).
#
# Conversion is most likely incomplete. It does some essential converting where
# I regularly experienced problems during migration.
#
# Use on own risk, always try with test databases first. No warranty at all!
