Free and open-source software (FOSS) is computer software that can be classified as both free software and open-source software.

That is, anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software.

This is in contrast to proprietary software, where the software is under restrictive copyright and the source code is usually hidden from the users.

Freenode, formerly known as Open Projects Network, is an IRC network used to discuss peer-directed projects.

Their servers are all accessible from the host names chat.freenode.net and irc.freenode.net, which load balances connections by using the actual servers in rotation.

In 2010, it became the largest free and open source software-focused IRC network and, as of 2013, the largest IRC network, regardless of focus, encompassing more than 90,000 users and 40,000 channels, gaining almost 5,000 new users per year.
