Denmark Data Breach Exposes 8.8M People's Personal Data

CPR har konstateret en alvorlig sikkerhedshændelse: En dansk virksomheds legitime adgang til CPR-systemet er misbrugt, og uvedkommende har fået adgang til navne, adresser, CPR-numre mv. for ca. 8,8 millioner borgere. Adgangen til navne- og adressebeskyttede personer var ikke omfattet. CPR-administrationen har stoppet virksomhedens adgang og arbejder sammen med specialister og myndigheder for at kortlægge hændelsesforløbet. Sagen anmeldes til Datatilsynet og efterforskes af politiet i samarbejde med relevante myndigheder. Mere information på ufm.dk.

Decision models like Jev don't beat LLM-as-a-judge or traditional classifiers

Red Hat OpenShift AI researchers benchmarked eight guardrails across nine models (pre-trained classifiers, BART-large-mnli, Shieldstral, Nemotron default/custom, Qwen3.6-35B, Laya Jev-style, DiffusionGemma Jev-style, Jev) on prompt-injection and content-safety tests via EvalHub. Pre-trained models remain highly competitive (e.g., Deberta-v3-base around 89% prompt-injection accuracy with ~54 ms latency). Large LLM-as-a-judge options like Qwen3.6-35B also show strong performance and lower latency than some rivals. Jev-style and open-source Gemma guards can match or exceed many baselines but need tuning. Laya benefits from task-specific prompts. Conclusion: no single winner; pick tools per task; lightweight, task-focused inference is promising.

Safe Optimistic Lock Coupling

The post argues that traditional lock coupling in concurrent trees causes root contention and poor scalability as cores grow. It advocates Optimistic Lock Coupling: writers lock and update a version; readers proceed read-only, repeatedly validating the version and re-reading if it changes. While scalable for lookups, it requires careful validation to avoid races. The article suggests encoding validation in the type system using unvalidated types, OptimisticPtr, and guarded access so that reads can be validated automatically, giving near-lock-free reads with safe concurrent writes.

Gods in the Classroom: Religion and Education in First Millennium BCE Babylonia

GODS IN THE CLASSROOM argues that 1st millennium BCE Babylonian education had no separate religious track; religious knowledge was embedded in the scribal curriculum. Students copied texts teaching the pantheon via An and Anum lists, learned divine names, and studied religious spaces, temple rites, and human–god relations. Babylon, under Marduk, was the religious–political center, while Nippur remained a regional center. Texts such as Tintir = Babylon, the Esagil Chronicle, Ludlul bēl nēmeqi, and the Counsels of Wisdom conveyed piety, kingship ideology, and elite professional norms. Scribes helped shape religious change across empires, with divergent northern and southern curricula.

Kagi Ends Orion Browser Development for Linux, Will Open-Source It

Kagi will stop developing Orion Browser for Linux and Windows and open-source both versions for community maintenance. The Linux beta will continue to run but won’t receive updates after Oct 2, 2026, and isn’t suited as a daily browser. Orion, built on WebKit (not Chromium), requires more resources, so Kagi will focus on macOS and iOS. The source code for both platforms will be released within 30 days, with no plans to maintain it; long-term updates depend on the community or open-source organizations.

Fixed Points and Strike Mandates

Khuong links fixed-point computations to real problems: for monotone f on a complete lattice, there are unique least and greatest fixed points. In practice, algorithms often converge to one extreme depending on initialization. Using dead-value elimination as an example, starting with all values live yields a correct but suboptimal least fixed point; choosing initial live-set differently can converge to the greatest fixed point. He then maps this to Quebec student unions’ strike mandates, which are monotone; the natural goal is the greatest fixed point—the largest set of unions that go on strike. Initialization thus guides convergence and speed.

A 40ms Go garbage collector pause caused by swap

Go GC pauses can spike when swap is involved. In a two‑process cgroup, the GC stops the world to read metadata that may be swapped; kernel eviction by age causes major page faults and disk I/O, producing ~40 ms pauses (two stop-the-world points: sweep and mark). Median pause ~51 µs; worst bursts around 39–40 ms, with 312 such pauses in 30 minutes. Building a 511 KiB message jumped to 105 ms on NVMe and 903 ms on a network volume. Go 1.26 Green Tea changes have negligible impact. Repo: github.com/frnsimoes/go-gc-swap-cost.

A tribute to one of the best games on the Atari 2600

River Raid (1982) by Activision, designed by Carol Shaw, is recreated as a JavaScript port that rewrites every 6502 instruction from the original ROM, not an emulator. The code reimplements the game on 4,096 bytes, generating the river in 32-block sections on the fly from a deterministic 16-bit RNG seeded A814, so the river is endless and exactly the same each play. A tanker, helicopters, jets, fuel depots, bridges, and houses populate the river; fuel management and crashes determine lives. The port is verified against the ROM with byte-for-byte parity; source on GitHub; not affiliated with Activision.

Nearly 200 People Under Observation After Irkutsk Lab Worker Dies from Plague

Irkutsk region authorities say nearly 200 people are under medical observation after a laboratory worker died from plague. The deceased, an employee of the Irkutsk anti-plague institute, reportedly broke a tube with live bacteria. She was hospitalized in Shelekhov, placed on a ventilator, and died; the hospital was quarantined. About 197 contacts are under monitoring, with over 100 in hospital wards. Officials say there is no plague outbreak in nearby Buryatia and all identified contacts tested negative; the plague form hasn’t been publicly specified, though pneumonic plague was cited by some media.

ArtCraft Apps – open-source Adobe compatible suite written in Rust

ArtCraft's Crafting Apps are seven open-source, native Rust tools for creative work: PhotoCraft, VectorCraft, FilmCraft, LightCraft, PrintCraft, EffectCraft, and DesignCraft. Each app is built from scratch, runs locally on macOS/Windows/Linux, uses no cloud, and preserves familiar workflows. They can be automated via CLI/APIs, and some run as WebAssembly in a browser. All are open-source on GitHub, with ongoing development and contributions encouraged via Discord for future crafts.

In the wake of closure, a digital archive of animated materials appears online

After Tippett Studios closed in August 2026, an anonymous donor, known as “TippettFan,” purchased a disc folder from the auction, digitized it, and uploaded it to Internet Archive as ISO disc images. The collection comprises 90 non-duplicated discs from Phil Tippett’s archives. Some clips are viewable online (CGI test creatures, a 2008 Tippett interview), but most files are downloadable, including behind-the-scenes images from RoboCop, Starship Troopers, Star Wars slides, and Catwoman publicity stills. The free archive is a large, ongoing treasure trove for historians and fans.

Interview with Chicken Scheme Maintainer Sjamaan/Peter Bex

Peter Bex, CHICKEN Scheme maintainer and Clojure developer, discusses his path from a C64 to Lisp, CHICKEN’s design philosophy, and his deep work on the CHICKEN core, irregex, and the numeric tower. He argues Scheme’s minimal core enables experimentation but standardization (R7RS, SRFIs) creates tension, notes CHICKEN 6’s integration of R7RS and module changes, and reflects on development history from CHICKEN 4–6. He favors Postgres over MySQL/SQLite for reliability and performance, critiques SQL, and values REPL-driven experimentation (though not at the expense of test suites). Off the keyboard, he values family, health, and teaching kids Scheme.
