A week ago, on August 18-19th, was held the first developer event in the XMPP
|
|
community for a long time.
|
|
|
|
The idea came up at the [Gulaschprogrammiernacht][0], in Karlsruhe earlier
|
|
this year, talking with Daniel Gultsch, and JC Brand. We gathered there to
|
|
work on an implementation of [OMEMO encryption
|
|
mechanism](https://conversations.im/omemo/) for
|
|
[conversejs](https://conversejs.org), and [poezio](https://poez.io). The
|
|
former is currently being merged, the latter is taking a bit more time, but
|
|
we'll get there eventually.
|
|
|
|
JC mentioned sprints organised by the Plone community, and I felt that was
|
|
something we were missing for XMPP. While the XMPP summit is held every year
|
|
before FOSDEM, it is often more oriented towards protocol discussions.
|
|
Developer events are scarce.
|
|
|
|
I set a goal for myself to start a movement in the community, gather
|
|
interested people, and work together to improve the ecosystem.
|
|
|
|
The first event -- of this hopefully long series of events -- was held two
|
|
weeks ago, sponsored by my employer, [Collabora](https://collabora.com), in
|
|
their UK office in Cambridge!
