On this very machine, along with this blog, I host many WordPress installations for development purposes. Some use the latest stable version while some use nightly builds. A few weeks ago, I decided to write a simple bash script to automate this process. It runs once a day and keeps all my installations up-to-date. You can get it from GitHub as usual.
If you are a WordPress Move user, than you might probably have tried to use the database backup created by WordPress Move outside the plugin and failed. WordPress Move creates database backups by serializing SQL queries to make parsing it easier so they are not in the plain-text form that you can use outside WordPress Move. Even though this works like a charm, at some point you may need an actual backup of your database which is why I wrote this small script that converts WordPress-Move-only database backups into generic SQL files. You simply put the files you want to convert into the directory called in and run the script to get converted versions of them from the directory called out. I also integrated this script right into the Backup Manager of WordPress Move with the version 1.3 I released yesterday. You can obtain the script from GitHub.
About a month ago, I wrote a simple Post-Receive URL implementation that sends an email to specified email addresses whenever a team member commits. You can create a whitelist of repositories you want it to accept requests from and also set HTML headers and footers for emails. I actually developed it for the developers of ollaa but it is available for everyone to enjoy at GitHub. Use it, fork it, do whatever you want. I hope it helps someone out there :)
