Cool DevOps Tools - Gerrit and Let's Chat

I would recommend all teams to leverage the following open source tools to add more juice to their DevOps operations and improve team collaboration.

Gerrit - A valuable web-based code review tool that comes with Git embedded. Can be very useful to help your junior team-mates learn about good coding practices and refactoring. A good introduction video is here - https://www.youtube.com/watch?v=Wxx8XndqZ7A

Let's Chat - Digital Natives don't like to write long emails and abhor email chains. Use this on-premise hosted web-based chat server to create discussion rooms and share knowledge and get questions answered.

JavaDB (Derby) in JDK 1.6 and above

JDK 1.6 and above ship with a default pure Java database called as "JavaDB". Is is based on the open source Apache Derby project.

By default, on a Windows platform JavaDB gets installed at "C:\Program Files\Sun\JavaDB".
Set the 'DERBY_HOME' system property to this path. Also put 'DERBY_HOME/bin' in the PATH property.

There is a good tutorial here that should get you up and running with JavaDB in 10-15 mins :)

Derby does not have a default GUI admin tool, but one can use many third-party tools such as SQuirrel and others. I think JavaDB provides a good alternative to MySQL for some scenarios.
