@mavroudisv Thank you! Would be great to catch up some time after the summer. I will get back to you.

@part_harry_ Not true, check Williams original paper.

See you in Seattle!

@quasicoh There are no books about GRPO. For classical subjects for which there are textbooks where scholars have carefully organized the material, I find it vastly more efficient to learn from than the LLM. With that said, I am amazed by how good LLMs are at knowledge management.

[Kim Hammar @KimHammar1]

How can the IEEE xPlore and ACM online libraries be so bad despite their massive funding? Service is constantly down and ridiculous rate limit configurations. Even ArXiV is a significantly better service.

Our NDSS paper is now available: https://t.co/jBLupKysme See you in San Diego

[Kim Hammar @KimHammar1]

Building systems with agentic tools reminds me of declarative programming with languages like Prolog, just that instead of defining logical predicates and having an SLD-solver derive the solution, we define the constraints as software tests and then have the LLM solve it.

Last week in Singapore. #AAAI2026

[Margot Wallström @margotwallstrom]

Over 30,000 killed in just two days.
This is a massacre—and the world must act.
The Iranian regime has no legitimacy. It is a real threat to Iranians, to Sweden, Ukraine, Europe and the democratic world.
EU: designate the IRGC as a terrorist organization. Invite Reza Pahlavi to governments and parliaments. Act now.
