Menace sur Android: Google veut verrouiller nos téléphones

Société Numérique — 26/02/2026

Linus' take

"

En tant que supporteur des logiciels libres et de la souveraineté qui les accompagne, voici un sujet qui m’inquiète : Google veut fermer sa plate-forme Android à toute application qui n'est pas signée par un développeur agréé par Google. Le sujet fait débat surtout en Europe, où Apple a dû ouvrir ses iPhones aux applications étrangères. Maintenant c'est au tour de Google d'essayer de fermer son écosystème, ce qui enlèvera le peu de liberté qu'on avait avec Android.

AIs can’t stop recommending nuclear strikes in war game simulations

NewScientist — 25/02/2026

Carine's take

"

Even 3 years into the current AI hype, it is still difficult to differentiate between its true capabilities and salestalk. Hopefully military leaders have a more clear-eyed view of the technology, as it is clearly not ready to be deployed in high-stakes decision-making processes.

Anthropic ditches its core safety promise in the middle of an AI red line fight with the Pentagon

CNN — 25/02/2026

Linus' take

"

I always liked Anthropic's stance of doing the right thing and setting standards with regards to security and ethics in LLMs. Unfortunately, they budged and will now only define 'goals that we will openly grade our progress towards'. These goals will be non-binding, and future LLMs from Anthropic will blaze ahead even if they get bad grades. At least they stuck by their rules of 'no AI controlled weapons' and 'no mass domestic surveillance', although this has gotten them declared a 'supply chain risk' by the Department of War.

Can social media age verification really protect kids?

Rest of World — 19/02/2026

Olivier's take

"

I found this article interesting because it highlights the tension between protecting children online — not just on social media, but also on shopping, gambling and adult sites — and preserving privacy. The challenge of enforcing age laws without collecting sensitive data remains, regardless of whether the burden is placed on users or platforms. eID could be a solution, but only if it is truly privacy-preserving and only minimal data is shared and no logs are retained. How it is implemented by the authorities is crucial here.

I hacked ChatGPT and Google's AI - and it only took 20 minutes

BBC — 18/02/2026

David's take

"

This article is quite unnerving: a twenty‑minute hack shows how data‑poisoning can make LLMs tell tall tales, turning sci‑fi fears into real business risk. It’s a wake‑up call to demand provenance, adversarial robustness assessment and scepticism—because trusting chatbots without checking is like relying on a smooth-talking oracle with a hidden agenda. Critical thinking remains your best plugin.

04 March 2026: Open-source software services meet-up: special edition ‘Fragilités et souveraineté numérique’

 

Where? BC 410, EPFL in Lausanne or remotely via Zoom

 

Time? 10h30-12h00 (CET)


Why participate?

 

This OSS services meet-up on “Fragilités et souveraineté numérique” directly aligns with C4DT’s strategic theme for 2026 to advance trustworthy, sovereign digital infrastructures—and it takes place right on our EPFL campus on March 4, 2026.

 

This special edition, organized by C4DT, features external guest speaker David Monniaux from Université Grenoble Alpes, whose presentation “Fragilités numériques” on the fragility of our digital ecosystem kicks off a panel discussion on digital sovereignty in society, academia, and EPFL—with EPFL experts Khadidja Malleck (RCP operational director), Prof. Mathias Payer (Head of the HexHive lab), Rafael Corvalán (DSI director), and moderator Imad Aad from C4DT.

 

It’s a prime chance for researchers, engineers, and partners to connect with Switzerland’s RSE and open-source ecosystem, share practices on robust research services. Show up to showcase projects and tackle shared challenges like software robustness and long-term maintainability.

C4DT Observer #17, titled “Quantum Demystified: Engineering a Secure Future”

 

Why read?

 

This issue reflects the clear consensus from C4DT’s September 2025 roundtable: quantum computing is neither an imminent catastrophe nor a distant fiction, but a credible threat arriving within 5–15 years that demands action today. It explains why migration to quantum-safe cryptography must start now—by leveraging already-standardized post-quantum algorithms, crypto-agility patterns, hybrid schemes, and CBOM inventories—while addressing the broader organizational challenge of prioritization, vendor coordination, and building broad “quantum literacy” across Switzerland’s ecosystem. Beyond avoiding alarmism or complacency, it frames quantum as a governance and infrastructure opportunity to strengthen security and unlock applications in medicine, sensing, and beyond, rather than just an existential encryption threat.
