Très grand chercheur en informatique et pédagogue exceptionnel, il a été pour moi l'un de ces professeurs qui marquent et qui aident à trouver sa voie.

A comic titled "A Guide to Bird Photography." On the left are images of the photo you want, and on the right are images of the photo you'll get. In the first row, the photo you want is a well-framed shot (there's a gorgeous mourning warbler standing on a branch). In the second row, the photo you'll get: an action shot (the bird is a fleeing blur). Next, you want a bird in sharp focus (an indigo bunting perched). But you'll get exquisite leaf detail (the bird is blurry but the leaves are in perfect focus). In the third row, you want a striking portrait (a Swainson's hawk looking at the camera). But you'll get... why (a kingbird screaming as it flies in front of the hawk and blocks the shot). Finally, the photo you want is pure elegance (a great blue heron standing in a marsh). But the photo you get is a pooping heron - maybe I can fix this in post.

An oldie that I'm thinking about a lot while I try to take warbler photos at Biggest Week in Ohio.

Watching Spain and Portugal very closely, but please don't jump to conclusions. Lots of bizarre root causes in big power grids.

From one of the leading figures in industrial cyber security 👇

It’s too early to tell if what’s happened in Spain & Portugal was caused by a cyber attack or some sort of physical activity.

There’s a history of jumping to the former conclusion before the latter is proved true.

We don’t yet know

Aujourd'hui, j'aimerais revenir sur cette annonce qui a fait le tour des rédactions et des réseaux sociaux :

"On a enfin trouvé des indices liés à vie sur une autre exoplanète !"

Comme d'habitude, des affirmations extraordinaires nécessitent des preuves extraordinaires.

On en est loin ici.

This is inaccurate. There is no known vulnerability with Signal's core tech. The memo was discussing phishing attempts, which Signal has worked to mitigate. And it was hastily reported.

It's important not to spread misinfo that can confuse people into moving away from meaningfully private comms.

What Really Happened With the DDoS Attacks That Took Down X Elon Musk said a “massive cyberattack” disrupted X on Monday and pointed to “IP addresses originating in the Ukraine area” as the source of the attack. Security experts say that's not how it works.

NEW: Security experts tell @wired.com that X was hit with 5 DDoS attacks on Monday, but that X likely went down because its infrastructure was left exposed. They also refuted Musk's claim that the attack originated in "the Ukraine area." @lhn.bsky.social reports: www.wired.com/story/x-ddos...

A subset of the Russian info op known as "Portal Kombat" appears to be constructed not for human consumption, but machines.

It's seemingly grooming LLMs to spit out RU propaganda precisely when we're taking our eyes off the regulatory ball. ⤵️

Former NSA, Cyber Command chief Paul Nakasone says U.S. falling behind its enemies in cyberspace In a wide-ranging speech and interview, Nakasone also talked about Trump administration moves and the shape of cyber offensive operations.

This is a big deal. I suspect we'll be hearing more and more about China surpassing the US in terms of its cyber capabilities, both in quantity and quality, over the next few months and years.
