Thank you #codeberg for all the hard work to offer an alternative! Onwards and upwards! 🚀

I had no idea that one day a Technology Connections video will make me emotional. But here we are. I really hope this reaches a lot of people that need to hear this and helps at least a little bit to make this place a little better for the long term. *big sigh*

You are being misled about renewable energy technology.
You are being misled about renewable energy technology. YouTube video by Technology Connections

If you call yourself apolitical and expect others and their youtube content to be apolitical. This is a video for you. Take your time, get a snack, and watch the full F’in video… you might actually learn something for once. www.youtube.com/watch?v=KtQ9...

@techconnectify.bsky.social thank you for the most recent video. I did not expect to end up being emotional at the end. But here we are. You put things in words that I could not have.

We always need to rest and make sure our hearts are calm and ready for their return whenever that might be. :) (on a bit more serious note I find listening to writers and how they manage inspiration quite educational)

Have you taken a break yet? It is important to stand up, walk, look out of the window or even better go on a walk. :) you can start when the muse is inspiring you :)

The language is only divisive if you are trying to put your head in the sand and pretend like everything is ok about this new and probably biggest bubble in history that will end up hurting everyone in tech when it bursts. Endorsing it only helps inflate it.

It is pretty well documented at this point that the LLMs are trained on indiscriminate scraping of the data with no regard to licensing and the creator use wishes. In essence theft. The data-centers are using excessive amounts of natural resources with no regard to people or pollution. Thus immoral.

If you want a dietary choice comparison. This is more comparable to: "A big corporation comes up with low cost, nutritious and very tasty new product called Soylent Green. People love it, it makes them more productive." and then trying to be nuanced about it :/

It is disappointing to see this stance towards AI from you. Harassment of any kind is wrong, but pointing out that using AI is immoral, based on theft and no one should in their good conscience use it is another. You are saying that its use is encouraged at Oxide. This is not what I expected :(

I've been busy trying to reverse engineer a fairly complicated circuit board.

Green Black Magic Probe v3.0 JTAG/SWD debugger and programmer with a built in GDB server. Mounted on top of a carrier board that provides a regular ARM Cortex debug connector and 0.1” pitch breakout pins for the debug lines and the AUX expansion connector. It also features a jumper to allow TPWR connection to the debug connector allowing the choice of how things  are powered.

For Black Magic Probe v3 development, I designed a little breakout carrier. We will likely spend some quality time with a debugger hooked up to it so I think it will be a worthwhile. The SMT threaded inserts are really nice. I also 3D printed a base to keep the TH pins from scratching the table. ;)

Biss and Abughazleh neck-and-neck in Democratic primary Over the past three months, 17 active Democratic candidates for Illinois’ 9th Congressional District reported a total of $4.7 million flooding into the competitive race. All the congressional candidat...

This is a grassroots campaign:

“Abughazaleh reports over $1.1 million in individual contributions under $200, making up around 74% of her contribution totals.
In contrast, over 90% of Biss’ campaign contributions come from big-money donations of over $200.”

Hey everyone! Tune in to @katmabu.bsky.social stream either on YT or Twitch. They are trying to prove that streams are better way to spend time of candidates than calling rich people for donations. Let's show their theory is correct! :) Consider donating at secure.actblue.com/donate/katst...

A Video impression of the #NoKings 2 march in #Eugene #Oregon It was a really pretty autumn day. Lot's of patriotic people came out. I hope you get some good vibes from it as I did. :) #nokings2 #resist #resistence

NoKings protesters. Some of the signs: “Due Process for All”, “Willie Nelso for President”, “Dump the Trump”. But the biggest one is carried by a person dressed in blue scrubs. Carries a “Operation Game” styled sign. A cartoon Donald trump is on the operating table and has a bunch of annotations. “Bird Brained Idiot”, “Forked Tongue Liar”, “Mean Hearted Bully”, “Taco Tits”, “Small D—K Energy”, “delusional Dictator”, “Cankles Crime King” he is holding also a crown in his hand.

More signs in the crowd. “I have a dream”, with police arresting Trump.

Caricature of a crazed Stephen Miller, holding a “naked cat”/“little baby” Donald Trump with empty eyes on his lap. Miller is pressing his vampire claws into Trumps back. On Stephen’s arm is a red armband with a part of a circle suggesting a “certain party” affiliation. The picture has a subtext “Peewee German’s Pet” which is a play on words with “Peewee Hermann” who was a US American comedy character known for being small and childlike. In the right lower corner is the date October 18th, 2025, the day of the second No Kings protest.

I feel bad involving Germans in any of this. But it works in the US context very well to convey a message. (see alt text for description) #nokings #nokings2 #protest #USA

I might be using codeberg (aka. forgejo) more in the future. I am unreasonably excited to see how many merge options it offers, but mainly "fast-forward only" is in there! ❤️ Why can't I have it on GitHub 💔

Nightly got the ability to resize avg graphics in place. That is definitely a step forward in the right direction. :)

If you are interested what feature request issues exist here is a link with the correct filter. If you are a KiCad user you might want to skim through that. There is a lot 712 issues at the time of writing… gitlab.com/kicad/code/k...

If it is not clear, if you think resizable logos/graphics in KiCad PCBs would be a useful feature consider upvoting the linked issue! Thanks~~~ ;) #kicad #pcb #electronics #opensource

Yeah I do the same, and this is why I created this feature request many years ago, even before KiCad moved to gitlab!

Wishlist: Add PCB object scale tool (lp:#1748311) (#2105) · Issues · KiCad / KiCad Source Code / kicad · GitLab Original report created by Piotr Esden-Tempski (esden)

I am bit shocked that there were only 2 other people in 7 years that also thought that having resizable objects (logos, graphics) for PCBs would be a useful addition. :/ Running campaigns around useful KiCad feature requests is something we should be doing? #kicad #pcb #electronics #opensource

Not sure where you get the "socially awkward"... I find you very approachable... :) But I know a lot of nerds, so my reference frame might be adjusted differently? 🤷

For some time @securelyfitz.bsky.social and I have been working on a new hardware security tool. A tiny m.2 WiFi module sized FPGA board allowing the access to the PCIe interface. You can sign up for updates for when the campaign launches, some time next year. #EpicErebus #fpga

Good news Homebrew friends! Now bmputil-cli has a formulae. This should simplify things especially for those that manage a lab with a bunch of machines! :) Just run `brew install blackmagic-debug/blackmagic/bmputil-cli` & profit! #opensource #debugging #embedded #electronics #rust #macos #homebrew
