#1Linux Security Mailing List 'Almost Unmanageable'

Linus Torvalds says AI-powered bug hunters have made the Linux security mailing list nearly unusable by flooding it with duplicate vulnerability reports generated by identical AI tools. Maintainers are now spending more time filtering duplicates and redirecting reports than actually fixing security issues. Torvalds is calling on researchers to use AI responsibly — understand findings deeply and submit patches, not raw AI output.

#2Enough with the AI FOMO, Go Slow-Mo, Says Domo CDO

Chris Willis, chief design officer at data platform company Domo, argues that enterprises are rushing into AI adoption driven by fear rather than strategy. He coins the term "tokenmaxxing" — spending heavily on AI access with no clear objectives — and warns that CFOs will soon demand accountability for AI spending. His advice: start small with concrete, verifiable use cases like automating invoice discrepancies instead of chasing moonshot projects.

#3Auto-Identity-Remove – Automated Data Broker Opt-Out Runner for macOS

An open-source macOS tool that automates the removal of your personal information from 500+ people-search sites and data broker databases on a monthly schedule. It searches broker sites for your name and state, locates your listings, submits opt-out forms (including solving CAPTCHAs via CapSolver), and tracks completion state to avoid resubmissions within 90 days. A self-hosted, transparent alternative to paid privacy removal subscription services.

#4Show HN: Files.md – Open-Source Alternative to Obsidian

Files.md is a browser-based, local-first note-taking app that works with plain markdown files — no installation required, just point it at a folder. The project emphasizes radical simplicity: the codebase has been deliberately kept lean for five years so a single person or AI can understand the entire system. It's a philosophical counterpoint to feature-heavy tools, betting that restrictions foster creativity.

#5The Foundations of a Provably Secure Operating System (PSOS) (1979)

A classic 1979 paper from SRI International proposing a capability-based operating system architecture designed for formally provable security properties. PSOS used hierarchical abstraction layers where each layer's security guarantees could be mathematically verified. It was one of the earliest serious attempts to apply formal methods to OS design, and its ideas around capability-based access control remain influential in modern security research.

#6Porting My 3D Points Renderer on a ZX Spectrum 48K

A developer ported a real-time 3D point-cloud renderer to the 1982 ZX Spectrum 48K, a machine with just 48KB of RAM and a 3.5MHz Z80 CPU. Through aggressive optimization — precomputed coordinate transforms, reciprocal lookup tables replacing divisions, and hand-tuned Z80 assembly — they pushed performance from 6.2 fps in C to 14 fps in assembly, with a precomputed animation path hitting 40 fps.

#71024000² Blocks: 2B2T Minecraft Server World Download Project

A team completed the largest world download in Minecraft history — 24 terabytes of data from the legendary anarchy server 2B2T, covering a 1,024,000-block-square area captured over 109 days. Datamining the archive revealed over 600 stashes of stolen items and 2,100+ manually verified locations of player activity. The project required custom software, over $3,000 in funding, and was motivated by preserving internet history.

#8We Mould Trees to Grow into the Shape of Chairs

Full Grown, a UK company founded by Gavin Munro, trains living trees to grow into fully formed chairs, tables, and lamps by pruning and grafting young branches along shaped molds over 4 to 8 years. The result is a single solid piece of wood with no joins — a living furniture factory in a Derbyshire field with about 400 pieces currently growing. It's a radical alternative to conventional furniture-making that skips the 50-year grow-then-chop cycle entirely.

#9Math Jokes in Alice in Wonderland

Charles Dodgson (Lewis Carroll), an Oxford mathematics lecturer, embedded sophisticated math jokes throughout Alice in Wonderland aimed at his academic colleagues. The "four times five is twelve" passage actually works in base-18 arithmetic, the Mad Hatter's stuck tea party satirizes non-Euclidean geometry, and the Cheshire Cat's disconnected smile plays on abstract mathematical properties. These hidden layers were intended for educated adult readers, not the children who later adopted the book.

#10The Aperiodic Table

John Graham-Cumming's blog post explores the concept of an "aperiodic table" — a playful intersection of aperiodic tiling mathematics (like the recently discovered "hat" and "spectre" monotiles) with the structure of the periodic table of elements. The post connects breakthroughs in mathematical tiling theory with the familiar grid of chemistry, riffing on XKCD comic #3242 on the same theme. It's the kind of nerdy crossover that lives at the intersection of math, science, and visual design.
