Greater transparency in local government decisions – CitiLink project puts AI at the service of democracy The right of any citizen to access decisions taken in municipal council meetings, the main issues discussed, the way votes

Have you tried to find a specific topic in a municipal meeting minute? Endless pages. Slow searches. And giving up halfway through?

That’s where CitiLink comes in. Led by #INESCTEC, the project uses AI to transform dense municipal minutes into clear, searchable and meaningful data.

You don't have to dirty your soul to be a successful academic or a scientist. Have some fucking pride. Have some fucking principles.

If you think you DO need to do that, all I can say is that I beg you not to go into academia or science.

📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms).

It’s also concerning. 1/

In 1996, Brewster Kahle wrote "Preserving the Internet" for Scientific American. Nearly 30 years later, it’s striking how many of his predictions about digital preservation came true—and how many challenges remain.

Let’s compare 1996 vs 2025 🧵

I thought something seemed off about the the image posted below: it's a photo that's been edited and colorized by AI. Please don't do that.

Google’s adtech fine pulled at last minute over EU-US trade tensions | MLex | Specialist news and analysis on legal risk and regulation An EU antitrust sanction against Google that was scheduled for today was put on hold hours before the planned announcement, following opposition from EU trade commissioner Maroš Šefčovič and lobbying ...

Details needed, but ...

If fine is pulled as part of EU-US trade negotiations this is very impactful and very bad.
