Thanks for attending / Lost-and-found: USB-C power supply

by Harald Welte

Dear OsmoDevCon 2024 participants, thanks a lot for attending and contributing by your talks, discussions, comments and conversations. It was a pleasure meeting all of you [again] and I do hope to see all of you again at another conference soon. Lost + Found ============ During teardown, we found that somebody has left behind a Lenovo USB-C laptop power supply (date code in year 2018). It was on the desk roughly in the area where Philipp was sitting. However, Philipp checked and it was not his. If anyone is missing theirs, please let me know and we can see how to get it to you. Hotel room payment ================== I hope everything worked out as expected during checkout. If anyone was unexpectedly asked to pay for the room, please let me know. Only those working for non-sysmocom companies with an "osmocom related dayjob" should have been asked to pay the room directly to the hotel. Invoicing ========= For those of you in an "osmocom related dayjob" who are expected to cover the daily conference rates of the hotel: sysmocom will wait until receiving the final hotel invoice and then issue invoices to your respective employer. Video Recordings ================ The recordings still need to be cut before they are published on media.ccc.de. This will likely take a few weeks I'm planning to release an osmocom.org news item (RSS feed) and post here when they are available. Thanks ====== I'd like to again thank our Sponsors AMN (Gold Sponsor), WaveMobile (Silver Sponsor) and sysmocom (Silver Sponsor) for generous financial support making the event in its 2024 format/venue possible. I'd also like to thank the c3voc team (specifically derpeter and Jake) for recording / editing / publishing the talks. Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> https://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Can someone do some experiments for me on the E1 BTS at ODC?

by Mychaela Falconia

Hello OsmoDevCon participants, As much as I would love to join you this weekend, I am currently unable to travel outside of USA+Canada+Mexico territory - that's what happens when you lose citizenship in your birth country without acquiring new citizenship in the country of residence... However, I hear that there will be an Ericsson BTS set up in the meeting room at ODC, and I wonder if someone among the attendees could perform a few experiments for me which I would have performed myself if I could attend. I am seeking a full capture of the uplink output from the BTS on a TRAU sub-timeslot (or capture the whole TS to make it easier) for a call, in all 3 classic codecs: FR, HR, EFR. With all 3 codecs, I am looking for BTS UL output with 'dtx uplink' enabled in OsmoBSC config, and with these two tricks performed during the test call: a) alternate between speaking into the mic and silence, so the MS will go into some DTXu pauses; b) press some DTMF keys during speech (not during silence) to exercise the scenario of active speech frames being stolen for FACCH. My main interest is to see what the BTS puts into traffic payload bits (alongside with BFI=1) when absolutely nothing was received on UL (no burst midables picked up) or when the received UL was FACCH - but of course I might spot something else that looks interesting if and when I get to look at some TRAU-UL captures with my own eyes. I have never owned or laid my hands on any kind of T1/E1 BTS, hence I have read the specs, read Osmocom code, but have no actual experience seeing what real historical BTS implementations actually do. Hence I am looking for some real UL output captures from _some_ E1 BTS. Note how I said "some" E1 BTS: at this point I would be happy to see a capture from any E1 BTS, no matter which vendor. I am asking about Ericsson right now simply because I keep hearing that there will be an Ericsson BTS in the ODC meeting room, but if someone has a Nokia BTS available/accessible for play, I would be just as happy with a UL capture from that one. In fact, a Nokia BTS UL capture might be even more interesting: I am in the process of acquiring a Nokia TCSM2 system (Nokia's term for the bank of TRAUs, 2nd generation), and if I had captured UL output from Nokia Abis, I could feed it directly to the Ater input of the TRAU. But back to Ericsson BTS at ODC, given how well GSM 08.60 format is standardized, if I had a UL capture from Ericsson, it would probably work just as fine as input to Nokia TRAU - and of course I can always tweak the bits in my TRAU experiments. If someone at OsmoDevCon could do these E1 BTS experiments for me, I would be very grateful. TIA, Mychaela

OsmoDevCon 2024 build-up on Thursday evening

by Harald Welte

Hi all! This is JFYI for those of you who will be present already on Thursday: I'm planning to do some build-up (power cabling, Ethenret switch, etc.) in the meeting room / venue Thursdays from about 5pm onwards. Feel free to stop by and say hi. In case there are no signs up yet: Ask the reception for the meeting room of OsmoDevCon. I don't know the room name yet, but for sure it's in the conference centre, which is an adjunct building that can be reached from the interior courtyard of the hotel main building. I intend to bring all equipment on my long list that day, so stuff like the DUG20+RUS etc. should all be on-site from that time onwards. One of the reasons to do this Thursdays is to figure out what might be missing so I can bring it on Friday morning. Any extra set of eyes figuring out what we might still be needing the next day is good too have. Looking forward to see all of you at the event, Harald -- - Harald Welte <laforge(a)gnumonks.org> https://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

OsmoDevCon 2024 - Updates

by Harald Welte

Hi all! This is an update on the OsmoDevCon 2024 planning. == Hotel reservations == All hotel reservations are made automatically by sysmocom. If you're listed at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2024#Confirmed then you have a booking with the conference hotel from the arrival to the departure date. Please check the table for your arrival/departure dates and make adjustments in case the table does not reflect your planned dates. DO NOT MAKE YOUR OWN HOTEL RESERVATION DIRECTLY WITH THE HOTEL, to avoid any double-booking, requiring double payment == T-Shirt sizes == We are currently working on a conference T-shirt. In order to produce them in the right quantity of the right size, please indicate your size in the table ASAP at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2024#Confirmed == Hotel room payment == Only those attendees who are marked with "No" in the "free of charge hotel+conference" column will have to pay for the hotel room (directly to the hotel). Those are attendees working on mobile communications in their professional capacity and where the respective employer covers the hotel. For all others (sysmocom team members and volunteers): The room bill (including breakfast) will be settled by sysmocom using sponsor funding (see below). In case there are any mistakes in this column, please contact me ASAP so we can get it sorted out. The idea is that no individual contributor/volunteer should be required to settle their hotel room bill. == Conference room + catering payment == Those attendees who are marked with "No" in the "free of charge hotel+conference" column will be invoiced by sysmocom. No attendee will need to settle any related bills directly with the hotel, unless you order spirits, long drinks or cocktails from the hotel restaurant/bar. == Call for Proposals == While the schedule is already getting crowded, we still appreciate any additional proposals you might have. Please submit via https://pretalx.sysmocom.de/osmodevcon2024/cfp The first draft schedule can be seen at https://pretalx.sysmocom.de/osmodevcon2024/schedule/ == Sponsors == We are very happy to announce * Africa Mobile Networks (AMN) as the Gold sponsor of the event * Wavemobile and sysmocom as Silver sponsors of the event Thanks for their respective generous support!

OsmoDevCon 2024 Registration + CfP

by Harald Welte

Good news, everyone [tm], after several years of break since the COVID-19 pandemic hit, it is my great pleasure to finally announce OsmoDevCon2024, our (previously annual) Osmocom Developer Conference for developers, by developers. The conference is held *May 3rd through May 6th, 2024* at the *Van der Valk Hotel Berlin/Brandenburg* conference hotel. Contrary to our past OsmoDevCons (which have all been rather low budget, grass roots events), laforge felt that particularly after the long COVID-related break, it would be nice to do something slightly more fancy: Stay together with the entire group for four days, in a conference hotel. sysmocom (and hopefully soon other) sponsors will cover the accomodation and conference cost for any volunteers contributing to Osmocom only in their spare time. If you have contributed to Osmocom projects in the past (writing code, funding, documentation, packaging or related activities) you are eligible to attend. Please register no later than March 1st on the OsmoDevCon2024 wiki page at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2024 At the same time, the Call for Proposals is open at https://pretalx.sysmocom.de/osmodevcon2024/cfp I'm sure after several years of a break, everyone must have hacked on (or learned about) many exciting things they would like to share. Any and all proposals are greatly aprreciated. Please don't wait too long so we can put together a draft schedule ASAP. Looking forward to seeing many of you again, Harald -- - Harald Welte <laforge(a)gnumonks.org> https://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

OsmoDevCon 2024 planning

by Harald Welte

Hi all! [cross-post to make sure everyone knows about it, please follow-up-to the osmodevcon(a)lists.osmocom.org mailing list for further discussion] As I mentioned several times at different occasions, I really think we should put together a OsmoDevCon again. In case you don't know what that is, please see https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon We should have restarted already in 2023, but I really was too busy and it was a somewhat difficult year for me at times, sorry. Date ---- In terms of timing, I am thinking about "after April but before the main summer holiday season (June-August)". That leaves May. Given that May has the whitsunday weekend as well as GPN (Gulaschprogrammiernacht, a CCC event that will likely conflict of interest with some people interested at attending OsmoDevCon), I'm currently considering the following candidate dates: * May 3 to 6 * May 24 to 27 This is as usual a friday-to-monday timeframe, allowing people who don't work professionally on osmocom to attend just the two weekendd days, while others can attend the full 4 days. Venue ----- In terms of venue, I'm hoping we can move to a slightly different arrangement where the whole group stays together for the whole duration of the event - as opposed to everyone staying at different hotels and having to commute from hotel to venue and back every day. So something like a hotel with a sufficiently large meeting room, hotels and catering all day. And all of that ideally at a nice venue with some kind of park / outdoor area, not downtown at the city center. Yes, that will obviously come at a higher price tag than we're used to - but I'm confident we can get that covered between sponsors and sysmocom. Do you guys think this is a good idea? Or would you prefer the traditional ad-hoc approach at IN-Berlin?

Osmocom Mailing List re-organization

by Harald Welte

Dear Osmocom community, This topic has been past due for way too many years by now: A re-organization of our major mailing lists. I would like to propose the following changes. Pleas let me know if you have any comments or feedback. I'm aware that renaming will mean people have to update their mail filter rules, but I think we're long past the point where the names of some of our lists started to confuse users. == openbsc(a)lists.osmocom.org == * openbsc doesn't exist anymore since OsmoNITB, which is also obsolete * does already cover anything "Osmocom CNI" related * Proposed new name: osmocom-cni(a)lists.osmocom.org == osmocom-net-gprs(a)lists.osmocom.org == This date back to when GPRS was a highly experimental add-on to our GSM code base. This list should simply be merged with openbsc@ as osmocom-cni(a)lists.osmocom.org == simtrace(a)lists.osmocom.org == Historically was created to cover only the simtrace project. We should rename this to osmocom-simcard(a)lists.osmocom.org or something along those lines. I would like to suggest it covers * SIMtrace / SIMtrace2 hardware + firmware * pySim and related tools for working with SIM/USIM/UICC cards * any other information / discussion related to SIM/USIM/UICC cards, like OTA, ARA-M, ... == osmodevcon(a)lists.osmocom.org == This has been a private list for people attending OsmoDevCon I would like to open up list membership to the general public, and ensure it also covers the new OsmoDevCall. We could then have discussions regarding feedback, topics, scheduling, etc. on that list. Maybe rename it to osmocom-events(a)lists.osmocom.org instead? To differentiate: osmocom-event-orga(a)lists.osmocom.org should remain a private list related to organizational / administrative topics of those involved with organizing future events. == nextepc(a)lists.osmocom.org == Should have been renamed to open5gs(a)lists.osmocom.org quite some time ago, I simply forgot about it. My apologies. -- - Harald Welte <laforge(a)osmocom.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Postponing OsmoDevCon 2020

by Harald Welte

Dear Osmocom community, during recent weeks, several of you have requested that OsmoDevCon 2020 be postponed to a later point in the year. Some, like Vadim and Rafael, have already cancelled their physical attendance meanwhile. I still have hope that the travel restrictions might be lifted again until OsmoDevCon happens in more than a month of time now, but that's of course a gamble and I realize people need to have some kind of reliable planning for travel, rather than waiting until the last day and then see if they can make it or not. With some reluctance, I therefore announce that we will postpone the event to a yet-to-be-determined later point in the year. We could try to fix a date now, but I think that doesn't make all that much sense until the situation has cleared up to some extent. I personally would suggest / prefer to move it to early October. Rationale; This is clearly after the usual holiday period (no idea if people will go on holidays in European summer 2020, but just in case). Please let me know what you think. Also, if you think we should converge tentative October dates already now, fine with me. It's really sad to not have our usual meeting. We won't have a chance to celebrate the 10th birthday of OsmocomBB. Meanwhile, all the best to all of you. Stay safe and sane, and by all means do continue to contribute to Osmocom - we're luckily working in a field where working/contributing remotely is the norm, and not the exception.

Cancellation of participation due to COVID-19

by Vadim Yanitskiy

Dear Osmocom community, it hurts me to make this statement, but unfortunately I have to cancel my OsmoDevCon 2020 participation in April. The borders are closing due to COVID-19, even between my home country and Russian Federation. I have been looking forward to see you all, but this time I won't make it. I've seen some ideas in the IRC about making it online, but it would not make much sense (at least to me) since we all work online anyway. Meeting face-to-face is what makes the event so nice. I know that most participants are EU/Berlin based, and the event can still be held. But would it be possible to reschedule it at a later date? Maybe in summer or autumn the situation would get better? I will keep my flight reservation until the end of March, so it would be possible to change the dates. Gesundheit! With best regards, Vadim Yanitskiy.

Tentative date for OsmoDevCon 2020

by Harald Welte

Dear all, I would like to suggest April 23rd through 27th as the dates for OsmoDevCon 2020. It's one week after Easter holidays end in Berlin and almost all other German states, so the hotel situation should be less crowded.

GPG keysigning party preparation

by Harald Welte

Hi all, as you may have seen, I've put a PGP/GPG keysigning party onto the agenda for this OsmoDevCon. It's a great opportunity to build a local web of trust, not only for verifying signed tags in our git repositories. I'm not an expert in key-signing parties at all, but given the small count of people (not sure how many are interested), I think we can do this rather ad-hoc in the classic way with 1:1 verification and don't have to go for optimized versions like https://en.wikipedia.org/wiki/Zimmermann%E2%80%93Sassaman_key-signing_proto… Based on https://wiki.debian.org/Keysigning it is recommended to print your key fingerprint on paper using the gpg-key2ps utility and then give out the snippets to the respective peers during the keysigning party while verifying their ID. If you don't have time to prepare ahead of the event: IN-Berlin has a laser printer and I'll plan to bring a paper cutter so you can create the snippets at any time before the key-signing party Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

More OsmoDevCon talks / discussions

by Harald Welte

Dear all, as you can see at https://pretalx.sysmocom.de/osmodevcon2019/sneak/ the number of talks / discussions / ... is still quite limited for a four-day event. If there's anything you'd like to talk about, or you'd like to hear somebody else about, please don't hesitate to submit it in pretalx. As usual, we can also schedule discussions, it's by far not only about fully-fledged presentations. Feel free to also suggest topics outside the classic theme of mobile communications, if you think there's something that could be interesting to the audience.

guest room available during OsmoDevCon 2019

by Harald Welte

Hi all, as Dieter unfortunately is not joining us this year, my guest bed/guest room is available during OsmoDevCon this year. So in case anyone doesn't yet have a room, or has a room that they can still cancel free of charge: Let me know if you're interested. Note: My home is not near the venue, but I'll be going to the venue and back every day anyway. It's about one hour by public transport, or probably around 40 mins by car or combination of car + public transport Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

XTRX price increase warning

by Alexander Chemeris

Thank you, everyone, for the OsmoDevCon! The great atmosphere this year. Several people wanted to buy XTRX at OsmoDevCon - if you haven't done that yet, we recommend doing that today. We've just sent a message to CrowdSupply to increase the prices of XTRX: XTRX - $260 Deluxe - $515 It may take them some time to do that but I don't know how much. -- Regards, Alexander Chemeris.

IMPORTANT: OsmoDevCon venue inside evacuation zone on Friday!

by Harald Welte

Dear OsmoDevCon attendees, this sounds a bit like a joke, but unfortunately it isn't. At a construction site about 600m away from the OsmoDevCon venue (IN-Berlin), an unexploded bomb from second world war was found. This bomb is going to be defused this Friday, which is exactly the first day of OsmoDevCon. For our international guests: This is not a very uncommon event. Even 73 years after the war, many German cities still have plenty of unexploded bombs in the ground, which are uncovered during construction work. It's usually not a big deal and the success ratio of defusing them is extremely high. However, of course, for safety reasons, police is evacuating a radius of 800m around the bomb site, which means *we are unable to use our intended venue this Friday!* You can find a map with the preliminary evacuation zone at: https://www.morgenpost.de/bin/bmo-214049359.jpg As you can see, not only is the OsmoDevCon venue at Lehrter Str. 53 affected, but also various nearby hotels, such as * A&O Hostel * Motel One Berlin * Jugendgaestehaus Berlin So if you are staying at any one of those locations, be prepared that from Friday 9am onwards you will not be able to reach or enter those hotels. To make things worse, Berlin central station (Hauptbahnhof) is inside the evacuation zone, too. It is expacted that all public transport, as well as regional and long distance trains are halted during the evacuation period. We're looking for an alternative venue on Friday and will keep you posted. If we can find one, this means we'd be at IN-Berlin only Sat, Sun and Mon, but would be at that different venue on Friday. German Police has announced to publish more details later today, on which we'll also keep you posted.
