The Event
Open Source 101 is a one-day conference featuring 10, 45 and 90 minute live talks covering the "basics" of open source. While many believe "everyone knows the basics" and can effectively contribute and consume, we disagree based on more than a decade of feedback and input from our community.

Registration is FREE
Thanks to our Presenting Sponsors registration in 2021 is absolutely FREE. Please visit these companies both before and during the event to say "thanks".

Access to the Virtual Environment
While programming will officially begin Tuesday, March 30 at 10:00 am ET, the virtual platform itself will be accessible the day before - Monday, March 29, starting at 4:00 pm ET. This will allow anyone interested to familiarize themselves with the environment pre-event.
