I am guessing it's the req_ctx.c / req_ctx.h? Thanks

OsmoDevCon 2014 / Date / Venue
by Harald Welte 01 Jan '14

01 Jan '14

Hi all, time is moving fast, and I want to start some initial discussion and planning for OsmoDevCon 2014. There are basically four questions which I'm raising below. Please provide your feedback to the osmocom-event-orga mailing list only, to avoid cross-posting over all the project lists. = Who? = My intention is to keep it an 'active developer/contributer only' event, like we had it before. I would also want to keep the group relatively small, to keep the 'Osmocom family' atmosphere. If desired, we could have one half or full day of public prsentations in a larger auditorium, but the developer meeting should be a close group, as known so far. = Where? = If we keep the number of attendees within the same range as this year, then I'm sure we could again hold it at the same venue. I know it is not perfect, but it is a place that we have access to, 24 hours per day, and free of cost for community projects like osmocom.org. If the community wants a larger event, then this is something that would require more funds and much more time organizing. And that is something that I personally could not offer to take care of, sorry. I'm happy to attend and support any larger events, but I'm unable to take care of fundraising and venue research. = When? = Q1/2014. In January, I'm not aware of any 'blocker' events. February, there is Fosdem (Feb 1 + Feb 2), and MWC from Feb 24 through Feb 27. In March there is CeBIT (March 10-14) and Easter holidays (with EasterHegg March 17-21). Did I miss any other FOSS / mobile event that might clash in Q1? So my preference woudl be to do it either late January (23-26) or in February (6-9 or 13-16). Any preferences regarding preferred schedule? Once we have some concencus here on the list [and we want to do it in the same size / venue], I'll talk to IN-Berlin. = What? = I think that question is easy to answer, if we have the above three figured out... There's no shortage of topics, I suppose. You can start adding your suggestions to http://openbsc.osmocom.org/trac/wiki/OsmoDevCon2014 Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Osmocom CardOS project gets its own list
by Harald Welte 15 Nov '13

15 Nov '13

Dear all, in recent weeks several people have contacted me that they would be interested in attempting to bring the idea of a CardOS forward. To provide them a place where they can share ideas and code, I have created the osmocom-cos(a)lists.osmocom.org mailing list. So anyone interested in this development: Please feel free to subscribe that new list: http://lists.osmocom.org/mailman/listinfo/osmocom-cos Regards, -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
