Good Monday morning – if your timezone is similar to London, Europe.
The next London Open Source Databases meetup is: Open Source Communities: vendors and users working together, 28th September. The speakers are Colin Charles, Businessperson, open source consultant, technical architect, experienced community builder; and Stacy Rostova (Raspopina), Communications Manager @ ProxySQL.
The subject is a bit unusual for our meetup. I wrote an article to explain why I believe it is essential to start talking about open source and communities: London Meetup – Open Source Communities: vendors and users working together.
Stacy also wrote an article which is worth a read – about what her experience taught her about communities: Community as No System. 7 Lessons Learnt from Years in Communications.
