Twitter is a self proclaimed advocate of open source projects. Heck, Twitter was built upon open source. So it makes sense then that Twitter has a long list of projects that various developers – or programmers to be exact – are working on at Twitter. To help you get more insight into the open source projects that are in the works at Twitter, they’ve launched an official directory of all Twitter open source projects.
According to TechCrunch.com, some of the more prominent programs you might recognize being used are familiar enough. Those such as Ruby, Scala, Java, C/C++, and other various tools. And some you may have heard of, such as Cassandra, the P2P structured storage network Facebook began in 2008. While some of them you may have not, such as Murder, the code deployment project that uses Bittorrent.
