DevConf.US 2021 has kicked off their call for papers this last month and of course it will be a virtual event (hopefully for this one last time) hosted on September 2-3. It’s the 4th annual, free, Red Hat sponsored technology conference for community project and professional contributors to Free and Open Source technologies coming to a web browser near you!
There is no admission or ticket charge for DevConf.US events. However, you are required to complete a free registration. Talks, presentations and workshops will all be in English.
