Integrating Alfresco inside a MediaWiki

Alfresco is this huge and complicated Enterprise Content Management System, and MediaWiki is a great engine for a internal Wiki. Together, you can create a really awesome infrastructure. I won’t go in further detail why and how I chose them, and how I customized them further – that might come in a later post. Today, I’m […]

Language Switcher for Wikipedia – my first Chrome browser plugin – Part 2
