Vous voyez, c'est pour ça que je ne prends jamais au sérieux les politiques qui disent que les caisses sont vides.
Parce que si on rembourse toujours les cures thermales par la Sécurité sociale, c'est qu'il nous reste du pognon à foutre en l'air.

Le CIR, c'est justement l'État qui finance, pas les boîtes. Exactement le type d'assistanat que les politiques de droite nous disent être néfaste pour l'économie parce que ça créé une incitation à ne pas se prendre en charge tout seul, car l'État le fait.
Il faut l'écrire à chaque fois.

Brand new paper with Roxane Cohen, Robin David (both from @quarkslab.bsky.social ) and Florian Yger on obfuscation detection in binary code doi.org/10.1007/s411... We show that carefully selected features can be leveraged by graph neural networks to outperform classical solutions.
Identifying obfuscated code through graph-based semantic analysis of binary code - Applied Network Science
Protecting sensitive program content is a critical concern in various situations, ranging from legitimate use cases to unethical contexts. Obfuscation is one of the most used techniques to ensure such a protection. Consequently, attackers must first detect and characterize obfuscation before launching any attack against it. This paper investigates the problem of function-level obfuscation detection using graph-based approaches, comparing algorithms, from classical baselines to advanced techniques like Graph Neural Networks (GNN), on different feature choices. We consider various obfuscation types and obfuscators, resulting in two complex datasets. Our findings demonstrate that GNNs need meaningful features that capture aspects of function semantics to outperform baselines. Our approach shows satisfactory results, especially in a challenging 11-class classification task and in two practical binary analysis examples. It highlights how much obfuscation and optimization are intertwined in binary code and that a better comprehension of these two principles are fundamental in order to obtain better detection results.

Vous avez sûrement déjà lu que la climatisation aggrave les canicules car l’air chaud rejeté à l’extérieur augmenterait la température des villes de 2 à 3°C.

Vérifions ce que disent vraiment les études scientifiques à ce sujet 🧑‍🔬

Last week I had the privilege to be invited to the first workshop of the TITULI project anr.fr/Projet-ANR-2... The project focuses on the analysis of mortuary rolls that were used during the middle ages to announce the death of a monk or a nun to monastic communities.

Le projet TITULI a pour ambition d'étudier une source méconnue du Moyen ge : les rouleaux des morts. Ces rouleaux contenaient des avis de décès que moines et chanoines faisaient circuler à travers l’...

I love the R community. A few days ago, I received a very clear bug report for my github.com/fabrice-ross... package. It turned out that the reported behaviour corresponds to a small set of tiny annoying bugs in the interaction between mixvlmc and logistic regression solvers.
