Soon I'll say hello to Hamburg

Some of my friends already know it: I'll be spending some 6 weeks in the city of Hamburg starting from June 21st. I can't talk about details of the particular project that I'll be working on, but I'm extremely excited since it's related to what I've been most passionate about recently: GSM networks and their security. And no, it's not about any software development and it is completely unrelated to OpenBSC.

If you happen to be in Hamburg and want to meet at some time to hang out, feel free to drop me an e-mail.

OpenBSC now has an API for integration with PBX systems

In recent days, we have finally merged a series of patches from Andreas Eversberg implementing what we call the MNCC [mobile network call control] API. Using this API, it is possible to glue existing PBX or other telephony applications to OpenBSC and thus add GSM extensions to your PBX.

So far, only Linux Call Router (LCR) has been extended to use this MNCC interface. Andreas reports that he has successfully established both mobile originating and mobile terminated calls to GSM extensions of his LCR PBX.

It's great to see this kind of contribution, especially in an area which I personally am not all that interested in... I still want to focus on the actual GSM side of things and implement more features as well as work on stability, the vty/telnet configuration interface, GPRS support and the recently-announced plans for implementing an actual A interface.

Right now, other projects require more time slices, but I'm still spending quite a bit of work on integrating better SMS support, with actual store-and-forward of messages in our SQL database.

I'll be talking about GPL violations at LiSoG on July 1st in Munich

At the LiSoG meeting on July 1st, I'll be presenting on GPL violations and their international enforcement.

The LiSoG meetings have been repeatedly pointed out to me as some of the best Linux meetings out there, with a lot of professionals from the Munich area being present. I'm happy to be invited to join and present, even if it means I'll have to escape for a day from my most exciting project in Hamburg.

So if you happen to be in the Munich area and interested in meeting with a crowd of Linux people and/or interested in hearing about GPL enforcement efforts, feel free join.. But you have to to register [for free], as per instructions on the page linked above.

OLPC XO1.5 samples has arrived for VIA driver related work

I've just received one of the few precious XO 1.5 samples, since I'm supposed to be working with Chris Ball and others at OLPC to help them with getting the VIA hardware fully supported, e.g. integrating/testing support for the specific panel, etc.

It seems to be booting fine the current xo-1.5 branch of the OLPC git tree, and the basic operation of all major peripherals is fine. Stuff like power management and support for DCON are still requiring some work, of course.

Today I'm still busy with generic non-OLPC VIA driver related work, but tomorrow I can hopefully look into OLPC related issues.
