In an IEEE conf. last week, NASA engrs explained how they fixed the Juno spacecraft’s failing camera in late 2023 by heating and slow-cooling (annealing) its electronics.

After 8 years in Jupiter's radiation belts, JunoCam image quality deteriorated.

Engrs suspected a radiation-damaged voltage regulator. JunoCam was heated to 77F and much higher in a later step. And the images got clearer!

Annealing can change the crystal structure of materials incl silicon chips.

Oh wow, #hamradio to the rescue

Remember that hurricane data that is being cut off by the US government? Guess who figured out how to get the data anyway?

It's important to give yourself, small, easy to achieve goals. That way you can quickly feel like you've accomplished things.

So this week I have planned the following.

1: Act strange
2: Be Weird
3: Make unsettling/inappropriate comments that are easily misinterpreted.
4: Paint the walls

Every odyssey has a destination

Two days ago, I contacted Adobe about disabling AI features on my account.

Adobe this morning:

Warning: fediverse scam alert

You've promised yourself that you'll sit down to just read a few toots and, two hours later, you've read 500+ toots, made six new friends, and installed Linux or BSD on your laptop.

What a scam.

On weekend I managed to connect all my selfhosted services that support it to the #Keycloak #SSO (single sign on).
Namely #Mastodon #Peertube #NextCloud #FreshRSS #Matomo and #grafana

Why to bother with such complication for apps serving only a couple of users?
First it's quite easy nowadays.
And second, because I want to get rid of passwords and just use #passkeys .

This is one of many examples showing that good apps should just focus on one task and just use standards to cooperate with other apps focusing on other tasks.

Peertube for example focuses on videos, not user management. I am very OK that they don't support passkeys, because they implemented OpenId Connect standard to allow me use Keycloak for better login options.

On the other hand, I am quite sad that SSO is often the one feature, that is proprietary and reserved only for paying customers. SSO is not for huge corporations anymore. It's also usefull for us, selfhosters with couple of users.

Hi, my name is Faye and I’m new to mastodon. I’m always making something whether it’s painting, making jewelry, sewing, or cross stitch. I do make my own cross stitch patterns and this one is one of my favorites. I enjoyed doing this mashups between a piranha plant and a xenomorph.

How Youtuber Louis Rossmann's beef with an Australian PlayStation repair whiz revealed a shocking past
https://www.abc.net.au/news/2025-07-20/youtuber-louis-rossmann-takes-on-better-way-electronics/105532410

This story takes some twists and turns.

For me, it's a reminder for me of several important points:
- People who do downright awful things in one area of their life/work/morals are usually terrible people in other areas.
- Some people have enough awareness to say "Sorry" to their victims, yet not show remorse or contrition. They do not change their ways, they are manipulative, and they think they're the smartest person in the room. They're incapable of showing sincere respect or gratitude toward other people. They're toxic, they're abusive, they're bullies, and they're acting as though "The end justifies the means" to get what they want.
- We should all have the right to repair software, hardware, and systems we own. Whether you're running a repair business, or are a Maker (or "Hacker" by the old-school definition), or are a regular person engaging in a hobby at home, we should be supportive of each other in these aims. It's wrong to impede these goals by abusing legal tools such as Copyright, DRM, and DMCA.

I wish someday to be half as happy as this turtle on a skateboard, chasing a cat ...

Is autism self-diagnosis valid? Yep. 💜

Hey all, after reading dozens of research papers, and meta-analyses, and living through it, I made a thing!

I'd love it if you'd check it out! 🥰

Update: I replaced the header image, now people can complain about the actual research instead of the thumbnail.

Also, before any more guys respond with gatekeepy opinions about my conclusions, try reading the paper first.

Another great video by @notjustbikes. Every which way you look at urban design, we are failing ourselves when we don't build cities for people.

Cars are never the solution.

04:30.. a moody sunrise. Thunderstorms loom.

did you know that the default Windows 10 desktop background is a photo, not a digital effect?

it's a Kvant Spectrum laser projector with Saturn 9000 scanners beaming light into a sheet of transparent acrylic with black cardboard masks.

there's even a short video showing an animated show variant of it here: https://www.precisionlasers.com/projects/windows10

US-based Canadian artist Carol Milne creates glass sculptures that mimic the patterns of knitting and yarn.

Her method involves aspects of knitting, lost-wax casting, mold-making, and kiln-casting to achieve the intricate, seemingly pliable forms of knitted glass.

wow, everyone is having a terrible day

theres something you all need to remember

Street scene.

When you get away from the gated residences and the high-rise luxury condos, life has a slightly different tenor.
