#1Norway's 2 Petabytes of Huawei Flash Storage and LLM Training

Norway's National Library is building a sovereign language model trained on Norwegian text, leveraging 2 petabytes of Huawei flash storage. The project uses the library's legal deposit mandate to access copyrighted Norwegian content for training, addressing the need for non-English-speaking countries to build AI systems that understand their own language and culture.

#2Magnifica Humanitas — Pope Leo XIV's Encyclical on AI and Technology

Pope Leo XIV's 2026 encyclical addresses the digital age, warning against a "technocratic paradigm" where profit-driven uniformity sacrifices the vulnerable. The document argues AI is "never neutral" because it takes on the characteristics of those who devise, finance, and regulate it, calling for technology to serve human dignity rather than concentrate power. With 1,173 HN points, this has clearly struck a nerve.

#3The Bootstrapper's EU Stack for Under 10 Euros per Month

A guide to building a complete tech stack using exclusively European providers for under ten euros monthly. It recommends Hetzner Cloud for hosting, Ahasend for email, Simple Analytics for tracking, Hanko for auth, and Mollie for payments — proving the EU ecosystem is finally mature enough to compete with US-centric defaults for bootstrapped startups.

#4Jensen-Shannon Divergence

The Jensen-Shannon divergence is a symmetric statistical measure for comparing probability distributions, improving on Kullback-Leibler divergence by always being finite. It's widely used in machine learning, bioinformatics, and NLP for tasks like comparing text distributions and measuring model divergence. Its Wikipedia page is making the rounds as a foundational ML concept refresher.

#5California Moves to Exempt Linux from Age-Verification Law

After significant backlash, California is amending its age-verification law to exempt Linux, with the amendment proposed by the same lawmaker who wrote the original bill. The law had drawn fire for requiring operating systems to collect users' ages — a technically impractical mandate for open-source platforms. SteamOS may still be affected by the regulation.

#6Japan's New Hypersonic Engine Could Make 2-Hour Flights to the US

Japan's aerospace team has successfully tested a ramjet engine designed for Mach-5 hypersonic flight. The ground combustion trial validated performance and thermal protection at five times the speed of sound. If development continues, commercial flights could reduce Tokyo-to-LA travel from 10 hours to roughly 2 hours by the 2040s.

#7C Extensions, Portability, and Alternative Compilers

A developer building an alternative C compiler documents real-world incompatibilities in major libraries like glibc, SDL, and bionic where code assumes GCC-specific extensions rather than adhering to ISO C. The piece highlights how nonstandard compiler features have become deeply embedded in widely-used infrastructure, making it extremely difficult for alternative compilers to achieve compatibility.

#8Mullvad VPN Exit IP Fingerprinting Mitigation Rollout

Mullvad VPN has rolled out a security mitigation for exit IP fingerprinting across 13 servers in Australia, Canada, Germany, Finland, France, Ireland, Norway, Sweden, and the US. The enhancement addresses privacy concerns related to identifying VPN users based on their exit IP addresses — an incremental but meaningful improvement to VPN privacy guarantees.

#9Toshifumi Suzuki, Founder of Seven-Eleven Japan, Has Died

Toshifumi Suzuki revolutionized Japanese retail by introducing the franchise convenience store model and developing sophisticated point-of-sale data systems that transformed supply chain efficiency. He built Seven-Eleven Japan into a chain of over 10,000 stores, fundamentally reshaping Japan's distribution system. A retail visionary whose data-driven approach presaged modern logistics.
