@23n27@dgc.social @salkinium@chaos.social Negative pitch and way too much power for its weight. I don't want to know how much money you have to crash into the ground to be able to fly like that.

As promised, I just made my KNX device stack public: https://github.com/ntrnnr/zweidraehte It's still not 100% done, but you can create TP1, IP and RF devices with and without KNX Data Secure. ETS product database generation is also included. I'll keep working on it! But now you can play around with it as well.

I need some automated test setup for the KNX devices. I now have BCU1, BCU2, System 7 and System B devices with TP1, RF and IP link layers. The latter three mask versions with optional security support. Add product definition generation code for the ETS. Add a client library that can partly program these devices. I can't possibly test all of these things manually by flashing, provisioning with key material and serial numbers, importing the devices in the ETS, configuring them, programming them and pressing buttons. I need devboards with multiplexed GPIOs, serial ports and JTAG connections to cover all of this properly and catch regressions. Also some kind of plugin that I can use to control the ETS... I bet I can hack something together here, but it's not going to be nice. Yes, there are the conformance tests, but they are relatively shallow in certain places and passing them doesn't guarantee that everything works. Not sure if test labs have their own set of tests in addition to the official testing suite covering more ground. How much shit do I need to build for this project? 😫

KiCAD just ignoring Wayland has made it unusable in version 10. The 3D viewer just crashes, copying requires hammering CTRL+C until stuff is copied, repeated key input by holding a keyboard button just stops. It's extremely bad right now. Let's see how long they can ignore Wayland until just every distribution moved away from X11. edit: What I mean by "ignore": https://www.kicad.org/blog/2025/06/KiCad-and-Wayland-Support/ edit2: Launching it with QT_QPA_PLATFORM=xcb seems to at least solve the constant crashing 🤞

Not to pat myself too much on the back, but the whole KNX framework that I have by now is just so awesome. I mean I spent a lot of time getting the Rust type system to do what I wanted it to do. Doing that pays off, everything just fits together really well. Off to starting a client library to talk to devices from a full-blown host for management purposes. I need to cook! And fuck the ETS!

Ich raste aus, wenn ich noch ein mal das Wort "Stromer", als Begriff für ein Elektroauto, irgendwo lesen muss, dass sich zu hundert Prozent wieder irgendson Boomer mit Klapphandyhülle ausgedacht hat, WEIL DAS JA SO WITZIG IST!!1?1?1 HAAAHAAA. "Stromer! VERSTEHSTE!? WEGEN STROM UND SO UND ABER EIGENTLICH AUCH LANDSTREICHER. STROMERAUTO!!!!1!1!1cos(0)sin(pi/2) HAHAHA!" Infantile Scheiße.

I just left the heat pump running in cooling mode during the day for the last few weeks. Seems we slowly got rid of all the heat stored in the house and it just stays at 22-23°C now. The whole system has just so much inertia that it takes a while for things to happen. Same in autumn when we start heating. It always takes a few days until the temperature settles. Let's see what happens during the next few days when it gets warm again.

Funny how DigiKey delivers solder paste in a cooling bag to me and how I, after arrival, just put the whole thing uncooled on a shelf for 5-10 years until it's empty. Also the datasheet talks about a shelf life of 1 year. Weird.

The whole bulk 3€ customs fee per item group story that the EU now enforces on foreign packages makes me extremely angry. This essentially kills hobby electronics. I haven't ordered at Mouser or DigiKey in a while and I don't know how they are affected right now, but still: The whole idea is so fucking braindead. Instead of just getting rid of the 150€ customs free limit, they do this. I now have to make sure to order more than 150€ to get to pay "proper" customs fees which are 0% on electronic parts. And then hope that the seller doesn't split packages up. If they do, you pay 3€ bulk PER ITEM GROUP. As I said: 100% braindead. You know what? Fuck the EU! I hate this club more every day for a while now. Shit like enforcing USB-C as a charging standard does not alleviate this, the lobbyism, corruption and surveillance phantasies.

Nächste Woche durchgehend 20°C... Was ist das? Wintereinbruch?

@azonenberg@ioc.exchange @tom_verbeure@mastodon.social HiDPI, HDR, variable refresh rates, fractional scaling, different scaling factors on different monitors with different pixel densities. All new features that didn't exist 20 years ago and I use all of them.

@23n27@dgc.social "What protocols should the new RF Transceiver we are going to release support?" - "Yes."

@janamarie@mystical.garden @23n27@dgc.social Wait, that's a thing? I thought I was joking.

@tom_verbeure@mastodon.social It's a more modern architecture that aligns better with how modern GPUs work. X11 is from the 80s and modern concepts have just constantly been piled up on top of an old architecture. By now even the Xorg developers themselves only do maintenance anymore and don't add new features. There's Xlibre, but well... It's not that you benefit immediately from it as a user. It's plumbing. But everyone is moving away from X11. Asahi Linux for example doesn't even bother supporting it on ARM Macs. They tried, saw it was too hacky and moved on to exclusive Wayland support.

@tom_verbeure@mastodon.social I really need to attend the flea markets you find this stuff on. It's unthinkable to even find this kind of gear even on eBay for sane prices here in Germany, it's wild.

If that's how the European Union thinks it should work, I'll simply not support it anymore. It's that easy.

@sad_electronics@fosstodon.org I always had a hunch that the Atmel Qtouch chips are some AVR as well.

That unsettling feeling when you are not at home and your self-hosted services aren't available anymore. After checking out the infrastructure, I discovered that my whole rack went down and everything in it rebooted: Fileserver, auxiliary smart home nodes, core switch and core router. But all of it just rebooted, it wasn't off for long periods of time. It cannot be the fuse or RCD, these wouldn't reset themselves, so it must be something else. I restarted all my services and started digging for the cause. First hunch: the UPS. I know that the UPS battery is pretty much fucked, but I thought I could get by just a bit longer before ordering a new one. After checking the manual, I found out that this particular Eaton UPS does a battery test every week. Hmm... So I checked my power usage metrics for the rack on my Grafana. Turns out every week at the exact time when the devices rebooted last night, the current on the outlet drops from 1A to ~110mA. This must be the battery test. So my current hunch: The battery is so fucked, that the testing procedure makes the line voltage drop so far that everything rebooted. Time to order a new one, I guess. And I can sleep again now, knowing that my house won't burn down in the next few days until I'm back home. Also I should hook up that USB port of the UPS to at least one of my nodes :D

@jerry@infosec.exchange That means I can continue watching the show and still enjoy the books afterwards because they are different? I started watching and then bought the books, stopped watching the series to not spoil me, but never really found time to actually sit down and read the books except on longer train rides or flights. It takes a while to get through that way...

@q3k@social.hackerspace.pl You are dealing with a bunch of cultural philistines.

Got my hands on the KNX EITT today: The official conformance testing suite used by device manufacturers and test labs with the harness and the test definitions. I already had the tests itself without the runner in a version from 2019 and which are part of the standard documents in PDF form. This is what I reimplemented with my own runner to already test the stack with patches applied to tests here and there because of reasons. How I got this today is a story over a beer at $conference. I don't even think this approach was strictly illegal. Let's say it got published voluntarily and you just have to find it there. now I need to prepare zweidraehte to run this against and see how much I actually stick to the standard.

No surprises in the GTA 6 gameplay trailer. Looks playable.

@ulldma@infosec.exchange Geil, mehr Futter für die TikTok-Klapphandy-Boomer! Ich kann die 3000 neuen AI-Songs über Dicky den gut bestückten Wal in der Wismarer Bucht kaum erwarten.

@cccpresser@chaos.social Aus reiner Neugierde: In welcher Software hast du das gemacht?

Thank you, Linux. By enabling this handler to emulate a pre-ARMv6 SWP{B} instruction, I can run my old armv5 binaries on a modern aarch64 system, but even with the rate limit, you are hammering my logs with this message. Who thought this would be a good idea? I cannot recompile these binaries, because I don't have the source code... It took a Fable session to find out what even happens, because before enabling that by writing 1 into /proc/sys/abi/swp everything would just get killed with a SIGILL. I also cannot use qemu-arm and binfmt_misc, because I need custom ioctls towards a custom kernel driver which aren't handled properly in the qemu usermode translation. Great! https://github.com/torvalds/linux/blob/master/arch/arm64/kernel/armv8_deprecated.c#L218C2-L219

Nicht, dass ich bezweifle, dass die Russen hier Spielchen spielen, aber DAS ist deren Indiz? Bisschen dünn. Vermutlich steht aber auch einfach in der "Presse" wieder nur gequirlte Scheiße.
