Liblfds

Liblfds (stylized liblfds) is a lock-free data structure library written in the C programming language. It is used for creating lock-free structures, which means that the data structure uses multiple threads in order to handle operations concurrently (similar to async computing). The library was initially released in 2009 without any license, effectively placing it in the public domain.

The forum originally used esoTalk as its forum software before transitioning to esoBB. After the forum was inundated with spam accounts, the developer chose to write his own forum code using a Postgres database with a Python UI, using iframes in order to display posts on the right-hand side of the page. (It's shit.)
