Boston Linux & UNIX was originally founded in 1994 as part of The Boston Computer Society. We meet on the third Wednesday of each month, online, via Jitsi Meet. |
Meetings and Events
Our group has been meeting since April 1994. We formed our group as part of The Boston Computer Society (BCS); when the overall BCS organization dissolved itself, we chose to continue on as an independent user group.
From June 1994 to February 2020, immediately prior to the CoVID-19 pandemic that began in March 2020, most of our meetings were held on the M.I.T. campus. Ever since then, we have been holding our meetings online at https://meet.jit.si/blu.org.
