Kabelsalat ist gesund! Equipment von @c3noc und @c3isdn auf der Empore von Saal 3 des #39c3

I'm currently looking for one or more volunteers to maintain the Openmoko USB PID + OUI service at https://github.com/openmoko/openmoko-usb-oui as the existing maintainer is no longer available. This is a service providing free USB Product IDs and Ethernet MAC addresses for the #FOSS and #OSWH community. Volunteers have to review of the PRs fulfill FOSS/OSHW licensing requirements before merging PRs. #usb #opensource

We'll be rescuing another Siemens EWSD digital telephone exchange. If anyone is interested in helping us with disassembly and loading into the truck in Munich on October 23rd/24th, please let me know - more information in German at https://discourse.osmocom.org/t/ewsd-abbauhilfe-in-munchen-am-23-24-10-2025/2312 #retronetworking #telephony #telecommunications #isdn

@hanshuebner if it was a kernel ABI, it would also not be broken. I regret that the same "dont break existing applications" rule does not apply for core parts of userspace infrastructure. Yes, it is annoying to keep compatibility. But IMHO it is a matter of professional pride and courtesy to consider even minority users. In #osmocom we have a rule that old apps always need to work with new libraries. Period. Sure, we only have 17 years of legacy so far, and it's a small community. But still.

So there's a decades-old mechanism (and actual standard) how programs lock serial ports on unix-like systems in /var/lock. it's used in practice even in 2025 and #systemd >= 258 simply breaks it with "we don't care". I am not a systemd opponent, but that kind of behaviour [without a prior community-wide discussion or providing patches for known-affected projects and a grace period] is just alienating users and developers https://github.com/systemd/systemd/issues/38563 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1110980 #systemd #debian

So, after spending two half days in a colocation filled with several decommissioned but fully complete [including software] Siemens #EWSD digital telephone exchanges, I am happy to report that two of them will be rescued. We've dumped the hard disks and done some initial disassembly. Full disassembly and relocation will happen in upcoming months. #retronetworking #isdn #TelecomHistory

In case you haven't seen it yet, check out the analysis of the devastating state of [mostly] modern #OpenSSL by members of haproxy at https://www.haproxy.com/blog/state-of-ssl-stacks - hard to imagine such massive performance regressions getting into mainline linux distributions unnoticed by the distributors. #linux #ssl

In case anyone wants to suggest what specific sub-topic within my areas of expertise they would want me to talk about at @easterhegg2025 - please do let me know. It's always hard for me to estimate popular interest.... #easterhegg #followerpower

And it's done already 🥳
Sending a 4ly board on one weekend and getting the board before the next one is ideal.

It was shipped one day earlier than the spec say so that might just be luck and won't work next time, we'll see.

@arby @eliasp die werden trotzdem nicht "from scratch" entwickelt, sondern nehmen ein existierendes uhrenmodul/chip/Design. Und das hat halt kein dcf77 support...

@eliasp @arby ich denke das Problem ist, dass DCF77 ein deutscher nationaler Alleingang ist, und demnach die sicher vorwiegend Chinesischen und für den globalen Markt entwickelnden Firmen keine Kenntnis oder kein kommerzielles Interesse haben, da eine Extrawurst zu bauen...

@johl ich nutze #IRC vermutlich täglich seit 30 Jahren... ausser email schafft das vmtl kaum ein anderes Kommunikationssystem.

@f4grx it's just solder/tin on the copper traces before applying solder mask. I rarely saw old PCB that don't have this. Not sure exactly why, maybe to prevent oxidization of the copper? I've seen some rumors that occasionally it was also used to increase current carrying capacity of some power electronics traces, but I'm not sure I'm buying that.

More pics from the NZ96

IGHfT (communications museum dresden) has just acquired a NZ96D (digital PBX built in 1988 in thr GDR) in ots original wooden crates, brand new. #retronetworking #telephony #gdr #ddr https://www.tag24.de/dresden/kultur-leute/museum-in-dresden-erinnert-an-meilensteine-der-telefonie-und-wird-jetzt-groesser-3347937

@23n27 interesting but likely the most expensive option...

@hrw sadly no magic hint on how to avoid getting sick at #fosdem like many attendees have ben every year even before covid ;) I'm considering to mask up his time, let's see if I can manage it two full days.

@23n27 this actually differs from project to project. The multi color printed natural aluminium colored face plate were likely from panel-pool. Plain natural colored aluminum ones likely laserteil24, and black anodized ones com from one of 3 suppliers and then go to Fischer Oberflächentechnik for anodizing... Haven't really found a one stop place yet. We plan to put many of the osmocom bgt modules up for sale in the @sysmocom webshop soon [TM].

@1000millimeter @Golemde sag bescheid wenn Du mal in Berlin bist. Es ist aber das allermeiste in Kisten oder Regalen, und steht nicht betriebsbereit angeschlossen herum. Oder in der Garage, dem Dachboden oder teils sogar Garagendachboden.
