🌍 ICC Replaces Microsoft 365 with openDesk
A landmark move toward European digital independence, underscoring a strategic push to reduce reliance on American tech ecosystems and strengthen sovereign open-source infrastructure.
The International Criminal Court (ICC) in The Hague is moving from Microsoft 365 to Open Desk, a European open-source platform developed by Germany’s Center for Digital Sovereignty (Zendis). The switch reflects concerns about dependence on U.S. technology—heightened since Donald Trump’s return to the presidency—and signals a broader shift toward European digital autonomy. The Netherlands is also experimenting with Open Desk through its ‘My Office’ public-sector initiative.

🧩 Fil-C: Bringing Memory Safety to C Without Leaving Its Ecosystem
A pragmatic vision for evolving C into a safer yet familiar environment, showing that security and performance can indeed coexist.
Graydon Hoare highlights Filip Pizlo’s Fil-C project, a Clang-based compiler extension that adds memory-safety checks and a concurrent garbage collector to improve spatial and temporal safety in C. Fully compatible with existing C/C++ code, it enables safer Linux userspaces with minimal changes and reasonable overhead. The initiative bridges classic C performance with modern safety practices inspired by languages like Rust.

🛡️ Reinventing Linux Security: The Systemd FLOUT Model
A pivotal rethink of Linux security architecture, signaling systemd’s growing ambition to unify and simplify how trust boundaries are enforced across the operating system.
At the All Systems Go! conference, Lennart Poettering introduced FLOUT—Frustrate, Limit, Observe, Undo, and Track—a holistic security model for systemd. He advocates unifying fragmented Linux security under a declarative framework using sandboxing, containerization, and verified disk images to improve reliability and recovery. The proposal seeks to replace ad hoc security mechanisms with consistent, system-wide principles.
