Fosdem 2019 Remarks

Fact that open source development is huge nowadays couldn’t be felt better than at Fosdem 2019, practically during the first day was almost impossible to move around even on the corridors. It is irrelevant to say that I gave up quickly in the morning trying to attend any session, after failing to find seats in two of the rooms I wanted to get in.
Therefore the first day resumed to hallways, expo areas and cafeterias, meeting and chatting mainly with fellow Kamailians and VoIP/RTC folks. I got also the chance to see again and catch up with couple of other projects and organizations, among them: FSFE, OSI, SFC, the main Linux distros, Fossasia or GSoC.
Back to real time communications, being again being again part of organizing team for the DevRoom and the lounge…
The lounge was available during the both days, as usual filled with many XMPP projects and devs, joined by the Matrix.org team. The SIP/VoIP folks were never attracted by the lounge during all these years, but we always had a stronger presence in the DevRoom.
The RTC DevRoom took place in building H, with a fair large space accommodating about 150 seats, allowing us to run smooth during the day. I haven’t done much on Sunday apart of helping around and chatting with folks just outside.
Henning gave a presentation on what’s new lately on Kamailio project. Asterisk, Matrix, Homer SIP Capture, reSIProcate and CGRateS had their usual presentations as well and WebRTC was also a relevant stake of the day. A new comer this year was the sip3.io project, another SIP capture and troubleshooting tool. Of course, some presentations were about XMPP, open source devs doing a lot of cool stuff with that protocol as well.
On Saturday, we had our informal developers meeting about Kamailio, among participants, besides myself (Daniel-Constantin Mierla), there were Henning Westerholt, Federico Cabiddu, Alexandr Dubovikov and Dragos Oancea. Four were also at the developers meetup in Dusseldorf and we agreed that was something very productive and we should do it again. Couple of ideas were discussed about short term development, more to be announced via mailing lists.
The top of the event was as usual the dinner, done by Kamailio project every Fosdem edition since 2009 (see who was there 10 years ago). Like in the past few years, we were joined by other VoIP devs participating in the DevRoom, being nearly 40 participants (to give few more names: James Body, Tim Panton, Dan Jenkins, Daniel Pocock, Joachim Vanheuverzwijn). Lot of fun and interesting discussions!
Big thanks to Voxbone.com for sponsoring it and to Torrey Searle for helping to organize the dinner!
And to attract more of you to contribute to open source (and Kamailio), I have to mention that I got one of the most amazing gifts in more than 17 years of OSS development: home made Belgian chocolate truffles, amazing taste (thanks Joachim/Zoiper)!
Till the next Fosdem, I am looking forward to meeting many of you at the next Kamailio World Conference, May 6-8, 2019, in Berlin, Germany! Registration is open!
Thanks for flying Kamailio!

Planning Fosdem 2019

Fosdem 2019 is approaching, so we surveying to see who from the community plans to go to the event. We also plan to organize again a dinner on Saturday evening, a tradition for our project at the past 10 editions or even more.
Henning Westerholt will give a presentation about Kamailio in the RTC Devroom.
Several other developers plan to go to the conference as well, among them Daniel-Constantin Mierla, Federico Cabiddu and Alexandr Dubovikov, therefore we open here the invitation to join for everyone in our community. Of course, at Fosdem will be developers from other VoIP projects, like Asterisk, Janus, CGRates, Homer, Jitsi, …
At the past editions we typically had two “kamailio” events:
  • (1) an “ad-hoc” developers meeting in the cantina (or other available
    room around) to discuss about short term plans for Kamailio — time and
    place being decided as we meet there between us (expected in the
    afternoon of Saturday or during Sunday).
  • (2) a dinner at a place nearby, with other VoIP folks joining us
If you plan to go to Fosdem and want to join the dinner, announce yourself on sr-users@lists.kamailio.org mailing list. Just be aware that you have to pay for your food and drinks at the dinner, unless we are going to be surprised again by a generous sponsor that covers partially or completely to dinner.
