The USENIX Annual Technical Conference (****USENIX** ATC**, or, canonically, USENIX) is a conference of computing researchers sponsored by the USENIX association. The conference includes computing tutorials, and a single track technical session for presenting refereed research papers, SIG meetings, and BoFs. There have been several notable announcements and talks at USENIX. In 1995, James Gosling announced "Oak", which was to become the Java Programming Language. John Ousterhout first presented TCL here, and Usenet was announced here. It is considered one of the most prestigious venues for computer systems research and has an 'A' rating from the Australian CORE Conference Ranking system. From 2021 onward, this is co-located with another premier conference, USENIX OSDI.
