Guess what I'm working^W wasting my life on.

Dear #hater ! I'm stoked that you care about me so much that you wrote me a personal message not about my work :D I'm afraid your attempt at an insult hasn't really done anything. Maybe you could get me to care if we got to know each other first. I don't bite. I'm genuinely interested in […]

You think Free Software has won? Think again. I explained it at @piwo : https://dorotac.eu/posts/fosswon/ Still don't believe me? Right now, @fedora is making more space on your computer for nonfree software they ship: https://www.phoronix.com/news/Fedora-43-Bigger-Boot-Firmware What about […]

Hey @kde you heard that I made a #kdeplasma plugin. How the heck do I publish it correctly? I managed to guess my way around, but when I try to install the archive I uploaded, I get this: > Installation of /tmp/ZAxSMp-master-kwlejka.tar.gz failed: The new package has a different type from the […]

🇪🇺Germany's Minister of Justice today: "Suspicionless #chatcontrol must be taboo in a state governed by the rule of law." Private communication cannot be placed under general suspicion. "Germany will not agree to such proposals at the EU level." […]

Spectrometer: 150EUR. Objectively establishing that it's cloudy outside: priceless. Thanks to wejn, setup was on the painless side: https://github.com/wejn/tobes-ui #optics #hardware #freesoftware #physics

What's the simplest useful thing I want on my desktop? A plain text area. Now that I made it, any other #kde user can have it, too! https://codeberg.org/dcz/kwlejka #linux #plasma #kdeplasma #freesoftware #desktop #clipboard #copypaste

How old is your main computer's operating system? Paste your `ls -lrt /`! Or whatever else is relevant. Mine's #fedora installed in 2013. Same laptop. $ ls -lrt / total 86 drwx------. 2 root root 16384 Jun 27 2013 lost+found #computers #os #operatingsystem

#germany #law - the court I'm dealing with requires special software to communicate with them. It's called #egvp and there are multiple business options, every one more expensive than what I'd lose by not communicating. Is there any #linux software for that? There is one web option […]

Shoutout to @kde for the quickest fix ever to any software I use every day: I report a #Bug , go out for a bike ride, and it's fixed when I'm back! Thanks a lot, folks :) https://invent.kde.org/frameworks/ksvg/-/merge_requests/79 Now I hope @fedora#bugwill include that ASAP :) #kde #plasma […]

Does anyone have experience with #lidar #sensors ? I got a broken vacuum cleaner with one and I'd like to play with it. But it's hard to reverse engineer the communication when the #vacbot doesn't (vac-)boot :) #reverseengineering #embedded #programming #hardware #askfedi

There was a #rust library to convert different data formats to text: #html, #pdf, #opendocument , so on. It was called something like "any2text", I don't quite remember. But I can't find a trace of it now. Does anyone know what it might have been? I'd like to index my files. #search […]

New year's resolution: file one actively annoying bug report per day. Instead of, you know, learning to live with suck. #freesoftware #opensource #bugs

Next stop: #datenspuren . Who else is coming? After that, the conference season is over for me. Good 2 weeks, but I miss coding. #datenspuren25 #datenspuren2025 #conferences

One email to the German credit agency, and two weeks late, I have my own product ID to connect my janky payment script to banks. That was surprisingly painless. The library I use no longer provides a default one, and they recommend getting one, so I thought […] [Original post on fosstodon.org]

Great #fiberoptic workshop by @karotte ! 1. Strip the #fibre 2. Place in the splicing machine. 3. Watch it display the FAKEST #hollywood impression of "MERGING NUCLEAR CORES" ever, complete with a nova of light in the critical moment. Only lazor sounds missing. There's no way this is a real […]

Ladies and gentlemen, preparing for my #mrmcd2025 talk. I legit thought the laptop was dead. Seems to be not glitching most of the time after recovering the account though. See you in the evening! https://talks.mrmcd.net/2025/talk/U87GK7/ #mrmcd

Hey #electronics, question for you. What small weatherproof, bike-proof, 4-pin connector would you use for signals? All I can think of is a custom pogo pin abomination, but there must be a better option. #askfedi #dyi #mechanical

This month is sponsored by random #wifi net and occasional but constant packet loss. Cannot connect: Network is unreachable. The connection has timed out. Problem loading page. Unexpected error occurred. #networking #travel

Do you also think #computers were a mistake? Having a check-in machine allows #hotels to save labor. There's no need for a person to sit at the desk waiting for arrivals all the time. Big victory: hotel staff is not waiting! Instead, the visitors who fall off the happy path waste their time […]

Short break home and back into the maelstrom. Hello #mrmcd, hello Darmstadt :) This time following Elvis: a little less conversation a little more hacking please. Taking my #microcontroller and async #rust :) #Jazda

Very late first rehearsal for my presentation at #mrmcd25 and it's not overlong :D I found a few bugs in the slides, too. TL;not gonna W: #ecs is nicer than object-oriented #programming . https://talks.mrmcd.net/2025/talk/U87GK7/ 3 days until #presentation ... #mrmcd #rustlang

Thanks to everyone I met at #akademy2025 ! Specifically the #kwin team who offered review powers for my input method work, but also those who have discussed how to turn the #eu #CyberResilienceAct law into a revenue stream for maintainers of #opensource. Thanks @discombobulateme , @AleixPol ! […]

Hey #rust community, crazy idea: A crate registry without #microsoft as a gatekeeper. If I started one, would you publish your library there? What should I name it? Background: you can't publish on crates.io without #github account = #microsoft's permission […]

Thanks #digikey. I know you're optimistic about my projects, but let's talk about 5000 units after I manage to make use of the 3 I originally wanted to buy. #electronics #retail

#mrmcd kindly agreed to host my talk this year! https://talks.mrmcd.net/2025/talk/U87GK7/ It's nothing special, I'll just give an introduction to the #ecs #programming pattern. Content warning: #bevy, #rust, #wayland, #smithay, lame jokes. ECS might be popular in #games, but it has some […]

I propose replacing calories with watt-hours. - Almost same value (1 kilocalorie / Calorie is ~1.1 watt-hours) - more intuitive for people who use electricity - never the confusing between calories (science), Calories (food, which is technically kilocalories), kilocalories, and 'kilo Calories' […]

Just procrastinating, nothing to see here...

Hey #kde folks, it's official now, I'm coming to #akademy for the second time :) Hope to see some good talks and make progress on the input method front. See you there next weekend! #akademy2025

Looks like I'm going to #mrmcd ! Anyone wants to share a hotel room?

#oscillators again. Is the MCU datasheet wrong? It says: CLXTAL1 = CLXTAL2 = 2*(CLOAD - CS) For CLOAD, it is crystal/ceramic load capacitance, [...] For CS, it is PCB and MCU pin stray capacitance. Okay. Then I found AN100 from TI which uses the classic: CLOAD = C1*C2/(C1+C2) If I assume […]

What the heck happened to 9-axis inertial sensors? I can find only 1 at digikey and it's 1. on its way out 2. pricey #electronics

I have a #microcontroller which specifies a 32.768 KHz #oscillator for the RTC. I have a 12KHz oscillator. I want to make the #pcb NOW. What if I use the 12KHz instead? Can I expect glitches? Why would the recommended spec even be so inflexible? Is that because of some time-dpendent internal […]

Ever try to work on something, but the only software for it sucks? You get frustrated in the "I can do it better" way and go back to using the bad tool? Uh, I'm not that person. One flow later... I did it better. https://codeberg.org/dcz/tfurca Tfurca generates #kicad symols of chips for you […]

Solder warriors, how do you protect your etched boards from corrosion? I bought this one a lifetime ago. Clearly homemade. It's covered with rosin. I thought rosin was corrosive to the traces. What technique is this? What kind of rosin is used here? #pcb #electronics #copperetching #askfedi

This just in: my friends chucked out a shitty "CO2" #sensor. Actually a breathalyzer: https://hackaday.com/2023/02/18/anatomy-of-a-fake-co2-sensor/ It's a really pretty design! And while the man in the video says it's useless, I actually started a CO2 sensor […] [Original post on fosstodon.org]

Did you pump up your tires? I just did and I kid you not, I'm >5% faster. Tires ate my last month's training progress. #bicycle #cycling #bike #BikeTooter

I have to #diy handlebar grips. What would you recommend that doesn't get slippery when sweaty? Long story short: the grip shift rubber came off years ago. Tape doesn't fit very well. #bicycle #BikeTooter #bike #cycling #askfedi

Today I learned about spiral ratchet #screwdrivers . You push, screw turns. The ones I've seen on sale in #germany take some unusual bits. Does anyone know where to get one accepting regular hex bits? (Germany) #tools #askfedi

#wayland input methods. I'm sorry to say #iced doesn't have enough people with review/merge rights, so my work making #chinese and #japanese #input good on Wayland is going nowhere. What are other #rust #gui libraries I could contribute to instead? #cjk #opensource #nlnet

@openstreetmap I noticed osm.org now uses #webgl for the slippy map. Having worked with #gpu drivers I keep that crap off on the web browser (which is as much an an untrusted context as it gets) for paranoia reasons :P Is there a fallback that folks like me could activate? #mapping #opengl […]

I learned #welding . It's awful! Now my head has more space for nonsense ideas no one needs! Like, leaf spring #suspension for a #bike trailer. Has anyone ever tried that? Is spring steel required? deflection = FL³/(4Ebh³) , right? I'm getting over 10mm thickness for 100kg load which is a […]

Psst... Hey, kid! Ever tried... #coding in proportional #fonts ? It's smooth, you know. Your eyes will feel incredible. Don't listen to typewriter geezers, there's nothing wrong with wanting your #text to look nice. Try it. For free. I code like this every […] [Original post on fosstodon.org]

Weirdest #bug ever. I have #podman with an open shell sitting in the background. Every couple of hours, it jumps to 100% CPU for absolutely no reason. Even when the screen is locked and I'm away. Until I press enter in the shell. I've never seen a shell come to life for absolutely no reason […]

About #gpl . If I buy a second-hand device with #linux on it, who's responsible for giving me the sources? It seems logical to me that the person I bought it from. But good luck getting sources from a private rando ( #sustainability #reuse ). On the other hand, my #isp sells me, say a #huawei […]

Is anyone here on #fiber #internet ? Did you get a device from your #isp ? ...is it running #linux ? I just realized I can't fnd any sources to the #telekom Glasfaser Modem on the internet. Did no one ever request the #code under the GPL? The device is powerful enough to use as a VPN endpoint […]

Finally, there's #fiber optic #internet connection at my building! Germany's internet is slow to come and expensive, but it did finally come. A decade after my friends in Poland got fiber in a similar place, lol (theirs is faster and cheaper). A question to experts about German ISPs. Does the […]

Remember #libobscura ? The project didn't attract a huge community, but it did teach me stuff so obscure that few people apart from the authors understand it. So I started writing it down, for everyone's benefit. If you had questions about #DMABUF, I try to explain it on my #blog […]

So I visited someone who used to work at a hospital in the '90s and I got this hand-made #vintage #pcb . The writing is Coronametrics Front End/Ultrasound the other side has 02/83 , could be a year. No solder mask, traces at weird angles, no clear grid, rusty […] [Original post on fosstodon.org]
