SPLASH is a programming language-related conference held since 2011, sponsored by the SIGPLAN special interest group of the Association for Computing Machinery (ACM). Its name is an acronym for Systems, Programming, Languages, and Applications: Software for Humanity. SPLASH is an umbrella conference for two longstanding conferences, OOPSLA and Onward! which are now tracks of SPLASH.
Onward! is a conference sponsored by the SIGPLAN special interest group of the Association for Computing Machinery (ACM). Onward! began in 2002 as a track inside of the OOPSLA conference. Starting in 2009, it was considered a conference, but remained co-located with OOPSLA.[12] When OOPSLA was replaced by SPLASH in 2010, Onward! co-located with SPLASH and one registration fee paid for sessions of either conference.[13]
