Part of GDP dedicated to research in some EU countries. Congrats to Sweden, Belgium, Austria, Germany, Finland and Denmark for crossing the 3% mark.
All the others should do much better if we want to keep our high quality of life in the future.

Faut-il boycotter l'IEEE ? Le CNRS condamne la crรฉation de la Repository License Fee Alain Schuhl, DGDS du CNRS, attire lโ€™attention sur les nouveaux frais de publication nommรฉs Repository License Fee (RLF) introduits par IEEE en avril 2025.

The scientific director of CNRS (France's biggest decentralized research institute) has expressed his insatisfaction with IEEE adding an additional fee for papers made available by authors.

I think all CVF papers will eventually be targeted.

Quality of scientific papers questioned as academics โ€˜overwhelmedโ€™ by the millions published Widespread mockery of AI-generated rat with giant penis in one paper brings problem to public attention

โ€œEventually these papers will all be written by an AI agent and then another AI agent will actually read them, analyse them and produce a summary for humans. I actually think thatโ€™s whatโ€™s going to happen.โ€ - Venki Ramakrishnan, ex-president of the Royal Society

I wrote a notebook for a lecture/exercice on image generation with flow matching. The idea is to use FM to render images composed of simple shapes using their attributes (type, size, color, etc). Not super useful but fun and easy to train!

Banking on AI is just a bad business decision, whether you're an administrator or a student in higher education. It will be like having HTML or Microsoft Word on your resume. It probably already is.

The AI hype reminds me of the rush to teach HTML in the 2000s.

What happened?

Everyone suddenly knew HTML. It ceased to differentiate you in the marketplace. It was like saying you knew how to use email. You couldn't really build a career on it.

A professor rabbit berates his bunny students 
โ€œCome on, guys! Easter is just around the corner! You need to know this stuff!โ€

He is pointing at a formula: 

X equals (2C multiplied by the square root of Y, over S) multiplied by (A plus D)

X = number of eggs required 
C = number of children partaking in egg hunt 
Y = average age 
A = area of garden 
S = size of eggs 
D = depth of undergrowth
