Funny, even on here, I still refer to things as "tweets" when I think about them.

“Boids Demo Reel” survived as a videotape cassette on my bookshelf for many years, then was digitized for a documentary around 2010. “Breaking the Ice” was on broadcast quality reel-to-reel videotape until 2023 when Tom McMahon and others worked on a remastering for the 50ᵗʰ SIGGRAPH conference.

This @zohrankmamdani.bsky.social video is absolutely INCREDIBLE. The numbers he cites, the strategy and results they produced — it’s the future. When have you heard *any* campaign talk about this, ever? (Video split in 2 to fit in Bluesky’s limits)

Having a bad day? World politics getting you down, heat too much to bear? Behold the Singer-theremin-hurdygurdy magic.

I'm reading Bartz v Anthropic, of course, from a very practical, interested perspective. ("What can libraries let me do, and how exactly can we stay out of jail?") The first thing I notice: I didn't realize Anthropic had rolled their own GBooks. Doesn't sound prohibitively $$$. 1/3

I am really quite charmed with MonsterUI monsterui.answer.ai It feels like that moment when Bootstrap came out way back when, and made everyones lives easier. See this great video tutorial for why: www.youtube.com/watch?v=gVWA...

And so it begins! #isws2025 #group7

Off to Bertinoro, Italy today for: International Semantic Web Research Summer School Knowledge graphs for reliable AI 2025.semanticwebschool.org Looking forward to being a participant, and not a tutor or speaker. Fun!

And as background music at high volume: "Levi Schechtmann, born in 1999 in Hamburg, is a German pianist redefining classical music by fusing it with hip-hop, electronic beats, and contemporary sounds." open.spotify.com/album/3BHHdM...

Just back home from the trip to SA, next week I will be at 2025.semanticwebschool.org Really looking forward to meeting new people and the intense week.

I’m currently on maternity leave. Biscuit-making opportunities are proving hard to come by, but I should have a couple of new sets to share soon. If you’d like to see more in the meantime: - ellahawkins.com - Instagram – @ellamchawk - Facebook – Ella Makes Cakes Happy National Biscuit Day 2025! 🍪

I do love a good fact check.

Repeat after me: There's no genocide happening in South Africa. White people have on average longer life expectancies, better educational outcomes, higher incomes, more wealth, better healthcare access, and more local and international mobility than any other racial or ethnic group in the country.

The amazing thing is the way that the truth is blended with falsehood. True stories of crime, but with collapsed timelines and fake statistics, real rally clips assembled over 10+ years that make these songs feel ubiquitous.. This is lies through curation.

Next week I will be in Johannesburg, and the following weekend in CT. Will be on vacation with two young adults and one old toppie. (who still likes to boogie) Any tips for cultural events, music venues, festivals etc. ?

How did we get here: Afrikaner Refugees edition. A 🧵 (backed up by research)

More, most excellent Afrikaans content: www.youtube.com/watch?v=MOEc... Crank up the volume, and enjoy. (ons is nie almal so nie)

Extraordinary to see the gap between how both pro- and anti-Trump Americans are talking about Afrikaners, and how almost anyone talks in South Africa. Antis, I know you think you’re helping but we generally frown on racial abuse in South Africa, even against your political opponents.

International scientific collaborations that involve the US are complex now, but a good start is to assume you're collaborating with the 18c. The state is largely hostile to science. Economic theory is mercantilist. Travel is difficult. Research funding depends on the goodwill of quirky aristocrats.

OK, enough moaning from me. What are Afrikaans people actually like? Like this: www.youtube.com/watch?v=-kLt... Beautiful doccie about some real people.

Watched this lecture last night: www.youtube.com/watch?v=q_ed... Incredibly clear and entertaining lecture by Richard Feynman, still useful today, explaining the nuts and bolts of our universe.

Dis altyd beter in Afrikaans. 🤣 Die Groot Tsek. Na die land van Trompie Mammon.

It feels so silly saying anything "normal" in these times, and yet this is what we must do. Keep on doing what we do, spread the understanding, build stuff, maintain "normality" for what it's worth. Reminder: "Do not go gently into that good night. Rage, rage, rage against the dying of the light."

Not all Americans are stupid, racist, greedy, lying, hypocritical fuckers. Nor are Afrikaners all backwards, dimwitted, religious twats. Some of them are friends and family, and I love them dearly. My heart goes out to the contingent of true mensch people in both camps hanging their heads in shame.

How can you so blatantly be a horrible person? It can't just be utter stupidity.

After being fairly rattled by this: ai-2027.com - I am re-reading the The Hyperion Cantos by Dan Simmons. (from 1990!) He was eerily prescient in his tales with regards to the AI clades, and other things like social media and communications forms. Hard SF for The Win! 🤖💀😍
