It took less than a day of me hanging out with my Italian friend before he did a Matté-and-Emilià-style “approved” and bro had no idea why that made me giggle 🥹

Historická zajímavost, která se váže k tomuto dni.
Dne 4. 12. 1989 byly zrušeny výjezdní doložky československým občanům.
Zrušení umožnilo vycestovat do ciziny pouze s platným cestovním pasem. V platnosti byly od 23. února 1948. Jejich konec pomohl pád komunistického režimu.
Modernity is a conspiracy to replace 'thick' desires (community, craft, transcendence) with 'thin' desires (likes, sugar, dopamine). Revolt by doing something slow. Bake bread. Write a letter. Code a tool for just one person.

67 students. 6 weeks. 87 infections.
A new study finds the real driver of school virus spread isn’t close contact — it’s air.
Poor ventilation (CO₂ >1000 ppm) nearly doubles transmission risk. Hours in shared classrooms (RR 3.17) matter far more than minutes spent near someone (RR 1.16).
It’s the air we share. Fix ventilation.

Your periodic reminder that there were typewriter pen plotters. Yes, a typewriter that would draw text. Or a plotter with a keyboard attached, depending on your view.
I've collected a few, plus other oddities with pen plotters in them. Have a look:

Today was the first time I had to deal with #workslop from a colleague. His task was to write a narrative final report for a small production grant that I received and he managed. He produced something that I'd be embarrassed to present, so I spent the past 3 hours rewriting it.
I'm reminded of what I heard 
@emilymbenderProf. Emily M. Bender(she/her) say: the only use of AI is to indicate resource constraints in your org. This person lost his father recently, so he used AI to produce the report because he was stressed.

One thing about "AI" is with the technology OpenAI has (large neural network plus manual tagging) you could've made the best search engine ever. There could be a Copilot where you describe what you wanted and it finds an example of it in the corpus of open source software. You could go from a fuzzy image description to a stock image. These would be better than buggy code and fucked up images. But they wouldn't do that because the *service* OpenAI provides is obscuring that the content is stolen.
🕙 Hurricane's NTP 🕚
Their "NTP Stratum 1" clocks are part of the global internet's network-time infrastructure which assists in defining reality (for most).
They've been rad since the 90s... so (to no surprise) just look at the IPv4 addresses they have allocated for two of their three NTP clusters.
clock.sjc.he.net (216.218.254.202)
clock.fmt.he.net (216.218.192.202)
The glorious x.x.192.x and x.x.254.x 💗
I haven't read everything, but I can't find anything Ms Rachel has said that I'd even consider like borderline antisemitic. She seems very careful.

I've never understood why some data breach notices say things like, "We have no reason to believe that your information was misused..." Like, why do you think a Russian ransomware gang would steal reams of your customers' Social Security numbers? For shits and giggles? No, they're using it for crime. Lots of crime.

Tidal is better than Spotify, but also the integration and APIs suck so much that I refuse to use it. Has all the same smells as Spotify, plus the usual smells you get from pre-Internet licensing.

This week I stood in icy cold water halfway up my shins waiting for a brief moment of light. This was the resulting image.

Is Patreon still a thing for you or would you rather see more artists and creators offering crowdfunding options on their own websites?
i appreciate how this is going to break in 2 years (and it already is on firefox) but it was made regardless. a unique kind of flash player :3
Good morning Fediverse. It's time for another JSON-LD rant.
What I have done with defining activities in fedi-herds violates every JSON-LD principle. I mean, I defined a bunch of activities and didn't assign them URIs. That must drive every JSON-LD lover into desperation.
Why did I do this? Well, I was building something. I didn't know what the final result will be. I still don't. I might want to change stuff quickly (and did! Can you find the CreateList activity?). Using JSON-LD stops me from doing that!! So if you want people to innovate, we desperately need them for the Fediverse, discourage JSON-LD.

I know #Tidal isn't perfect (and buying physical media or band merch is better, but hey, that is situational, I will only buy an album after I already like it), but this sort of thing makes me feel vindicated in choosing not to use #Spotify.
