defaults write com.apple.iTunes invertStoreLinks -bool YES

This makes those little right-pointing arrows in iTunes point to your library, not the iTunes Store. If you want the iTunes Store, Option-click instead.

this is something that strangely doesn't happen automatically on ubuntu
in Ubuntu, just add

send host-name "dapperbox";

to your /etc/dhcp3/dhclient.conf file

you might need to do a

sudo /etc/services/networking restart

On your Mac, you can now do

ssh username@dapperbox

instead of

ssh username@1.2.3.4

Check out man pmset for further command options!

sudo pmset -a disksleep 0 sleep 0

1) Download the launchd GUI, Lingon, from: http://lingon.sourceforge.net/

2) Add hourly job:

$RAILS_APP_DIR/script/runner 'ActiveRecord::Base.connection.delete("DELETE FROM sessions WHERE updated_at < now() - INTERVAL 1 HOUR")'

3) My launchd task plist file (yours will vary):

<?xml version="1.0" encoding="UTF-8"?>
DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

This html code makes an input box that looks like the one found at here (Under the search downloads box) It works only on macs(safari tiger only i believe) and does not validate. Note: type="search" is what makes it work.

<input type="search" name="blah" value="Search"/>

Some stuff won't compile with the shiny new gcc 4.0 on Tiger.
To use gcc 3.3 :

sudo gcc_select 3.3

To revert to gcc 4.0 :

sudo gcc_select 4.0

I had to reinstall Mysql because it wasn�t one of the things I backed up before erasing my hard drive. Since I�m now running Mac OS X 10.4 �Tiger�, I decided to set it up to start when the system boots, but the system for creating startup items has changed slightly. So I saved the following xml in /Library/LaunchDaemons/com.mysql.Mysql.plist:

<?xml version="1.0" encoding="UTF-8"?>
    DOCTYPE plist PUBLIC 
         "-//Apple Computer//DTD PLIST 1.0//EN" "
        http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
        <key>Labelkey>
        com.mysql.Mysql</string>
        <key>OnDemandkey>
        />
        <key>ProgramArgumentskey>
        
                /usr/local/mysql/bin/mysqld_safestring>
        </array>
        <key>ServiceDescriptionkey>
        Mysql 4.1 Database Server</string>
        <key>UserNamekey>
        mysql</string>
        <key>WorkingDirectorykey>
        /usr/local/mysqlstring>
    </dict>
    plist>

Note that I'm using the official OSX distribution of MySQL... but with a few changes to match your database location, you can get this to work with other installs (fink, darwinports, etc).
