Ontario auditors found AI Scribe systems used by physicians frequently misstate facts. In a test of 20 approved tools, 9 fabricated information or suggested unrecorded treatments; 12 inserted incorrect drug details; 17 missed key mental health issues; 6 fully or partially missed mental health details. Accuracy counted for only 4% of the score, while domestic presence weighed 30% and safeguards were small. No mandatory attestation was required. More than 5,000 physicians participate; no known patient harms reported. Recommends manual note review and a revamped evaluation focused on accuracy and safeguards.

UK MHCLG says it saved millions by replacing Palantir’s Foundry-based Homes for Ukraine IT system with an in-house solution. The Homes for Ukraine scheme matched hosts with Ukrainian refugees; Palantir had offered initial free support and later won contracts totaling about £10m. The in-house platform, described as more flexible and secure, aimed to cut running costs and gain sovereign control over data and code. Palantir says it helped accelerate refugee resettlement; the new system was brought into operation by September 2025.

An APL-obsessed game developer describes building a voxel game in Dyalog APL and a single line of code that computes which faces of a chunk are exposed. Using 3D boolean arrays solid and edges, shifting and outer product logic identifies visible faces; inspired by Game of Life. After inefficiencies, he added padding to avoid edge checks, dramatically reducing geometry and memory usage (vertices from 31.4M to 6.2M; video memory from 261MB to 72MB; render time from 11.2ms to 2.14ms). He merged it into a new line and says goodbye to the old one, reflecting on learning APL and DYNA26.

Synacktiv reports a bypass of Tesla Wall Connector Gen 3 anti-downgrade. After 24.44.3, the updater enforces a security ratchet stored in persistent memory and firmware segments carry VRSN/VRS2 data; the bootloader does not check the ratchet. The attack doubles the update sequence: push a current firmware to the passive slot and run 0x201 to commit a partition layout, then re-prepare the same slot to erase that image, and finally reboot with an old signed firmware. The bootloader will load it because the ratchet check never ran. Tesla patched it via OTA; risk persists until boot-time enforcement is universal.

An overview of GLP-1 agonists (e.g., semaglutide, tirzepatide, retatrutide) that curb appetite by signaling the brain calories are consumed. The piece explains energy metabolism: glucose, glycogen, fat, and ATP, and how hormones—GLP-1, GIP, insulin, glucagon—regulate hunger, energy use, and storage. Retatrutide targets GLP-1R, GIPR, and glucagon receptors, combining appetite suppression with enhanced energy expenditure; drugs are engineered for longer half-life by attaching fatty chains. Side effects include digestive issues, injection-site reactions, fatigue; rodent data raise thyroid-cancer concerns; drug interactions possible.

Ben Stone describes 3DMMEx, a Linux port of Microsoft’s 3D Movie Maker, making it the first known non-Windows fork. With the 2022 MIT-licensed source release, he teamed with Mark Cave-Ayland to port to Linux and SDL. They tackled a non-standard C++/Win32/Kauai framework, x86 assembly, and two static libraries (BRender, AudioMan). AudioMan was decompiled; a cross-platform miniaudio-based audio backend was added; SDL replaced Win32 GUI; 64-bit fixes and UTF-8 handling added. 3DMMEx now runs on Linux, though mouse dragging is imperfect. More ports and binary releases planned; GitHub project.

Germany’s Sovereign Tech Fund granted KDE €1.285 million to strengthen KDE core infrastructure (Plasma, KDE Linux) and security, joining STF’s earlier support for GNOME (€1m in 2023) and FreeBSD/Samba (2024). KDE Linux (Project Banana) is an immutable Arch-based distro in development, inspired by SteamOS/ChromeOS, with Igalia involvement. The funding highlights Europe’s push for digital sovereignty and homegrown OS options. France’s DINUM is pursuing a sovereign OS approach via a Nix-generated immutable image (Sécurix/Bureautix) rather than a full distro.

WinUI 3 performance is being aggressively improved to make apps faster. The team is focusing on launch-time improvements, using File Explorer and Notepad as benchmarks. Early results from the WinUI portion of File Explorer launch show: 41% fewer transient allocations, 63% fewer function calls, 45% less time spent in WinUI code, and a 25% reduction in overall launch time. Changes will ship from the development branch soon (winui3/main) and into WinAppSDK 2.x where feasible, with opt-in breaking changes (e.g., optimized default control styles) and a potential move to opt-out in 3.0+/4.0+.

Germany’s domestic intelligence service (BfV) reportedly rejected Palantir in favor of French rival ChapsVision, though no official confirmation exists. The decision centers on AI-enabled tools for counterintelligence and counterterrorism, amid planned legal reforms on surveillance, AI, and facial recognition. Civil-society groups (GFF and others) warn about transparency and potential fundamental-rights encroachments, while Palantir’s CEO criticizes Germany’s debate as restrictive. Parliament will have the final say on the reforms.
