William Whyte reviews Colin Kidd's Twilight of the Dons, a historical study of British intellectuals at Oxford and Cambridge from 1950–1980 and their collapse under Thatcher. Kidd defends a 'golden age' of open, cosmopolitan dons and argues Thatcherism damaged British culture by turning dons from the nation's conscience into a 'luxury cruise liner' for an international clientele, leaving a vacuum. Whyte lauds Kidd's depth, style and the mix of general history and stand-alone essays, but questions scope (omitting many academics outside Oxbridge and other universities) and whether 'decline' is the right frame; notes shifts to private enterprise and media.

An Intercept investigation shows La Tilde, a Latin America–targeting site funded by the U.S. government, operates as an AI-driven propaganda outlet for the Pentagon. La Tilde mixes personal-finance guides with fawning coverage of U.S. military actions (e.g., Maduro’s abduction) and discloses government funding in About page. It appears linked to SOCSOUTH/SOUTHCOM messaging, with no staff bylines and AI-generated content; production involves contractors like General Dynamics and Antpack. Plans to launch country-specific versions suggest broader influence operations.

POLITICO publishes The Browser Choice Alliance’s open letter to Microsoft accusing it of leveraging Windows and Edge to suppress browser competition. It cites rebates, blocking uninstalls, intrusive prompts, OS updates that push Edge, hardwiring Edge in Windows search, and restricted one-click switching. It requests worldwide reforms: allow preinstallation and default deals for other browsers; end dark patterns; restore single-click default switching for all file types and apps; open links to the user’s chosen browser; remove Edge banners and stop Edge-pushing updates; drop S-mode restrictions. It argues competition benefits users, especially for AI-era PC use.

Magenta RealTime 2 (MRT2) is an open, on-device live music model and real-time inference engine that lets you build and play AI instruments on Apple Silicon Macs. The 2.4B open-weights model runs with a C++/MLX engine and frame-by-frame autoregression for near real-time control via MIDI, text, and audio. Latency is ~40 ms per frame with end-to-end control around ~200 ms; runs standalone, in DAWs, or via the magenta-rt Python lib and example apps. Supports notes, drums, and style control through MusicCoCa embeddings; future plans include finetuning and more demos.

Delacroix’s Entry of the Crusaders into Constantinople, a major 1840 history painting once darkened by varnish, has been restored to its original brilliance and returned to the Louvre’s Red Rooms. Commissioned for Versailles by Louis-Philippe, it moved to the Louvre in 1881. The conservation (May 2025–April 2026) reinforced the canvas, removed aged varnishes, applied a transparent varnish, and filled paint gaps. Scientific imaging shows Delacroix’s dramatic composition—violent sack of Constantinople, foreground captive women, and banners—now revealed through his technique (flochetage) and a vivid, unified color palette. The project, supported by Isabelle Ealet-Corbani, caps a years-long restoration campaign.

Wifi Time chronicles an abandoned attempt to create a 'fake GPS' module for a Precision Clock using an ESP8266 to obtain time over WiFi via NTP. The goal was sub-millisecond accuracy, which proved impractical, so the author documented experiments comparing the ESP8266 PPS to a real GPS PPS with a logic analyzer, plotting offsets, and tuning a control loop. Improvements came from using time.cloudflare.com and testing on different networks. In the end a TCXO would have been simpler; the project is unfinished, with source on GitHub.

The piece alleges SpaceX operates with impunity, citing OSHA violations, a fatal Starbase incident, and a high rate of unreported injuries. With a June 2026 IPO planned, insiders are rushing to cash out via debt-fueled deals (involving xAI, Tesla ties, and other Musk ventures) as markets ease profitability rules for mega-caps. The article portrays SpaceX as a symbol of a Ponzi-like stock market that funnels wealth upward, leaving ordinary investors to bear the risk.

HPPIE tests whether inserting a patient persona at retrieval closes the clinical relevance gap in RAG for healthcare. Standard RAG lacks patient history, yielding “fragmented awareness” and potentially unsafe results. The three-stage pipeline: Stage 1 pre-retrieval Persona Modeling injects structured attributes (age, meds, conditions, allergies) into the query embedding; Stage 2 Hybrid Scoring blends embedding similarity, BM25 clinical terms, and a persona-driven behavioral score; Stage 3 on-prem Local Inference with Ollama to protect PHI. At a global AI hackathon, HPPIE placed 2nd of 300+, producing persona-specific results. Open challenges: incomplete data distorts the persona and risks confidently wrong outputs; production scale, costs, and governance need validation.

Go experiments are features-proofs that may graduate, be paused, or be dropped. They follow three states: off-by-default (under evaluation or dormant), on-by-default with an opt-out, and permanent experiments (off-by-default but not expected to graduate). Enable via GOEXPERIMENT. As of Go 1.26, permanent: FieldTrack, StaticLockRanking, CgoCheck2, BoringCrypto; on-by-default: LoopVar, Dwarf5, RandomizedHeapBase64, GreenTeaGC, RegabiWrappers, RegabiArgs; off-by-default: HeapMinimum512KiB, Arenas, NewInliner, JSONv2, RuntimeSecret, GoroutineLeakProfile, SIMD, RuntimeFreegc, SizeSpecializedMalloc. For most users, focus on GreenTeaGC, Dwarf5, JSONv2, GoroutineLeakProfile, RuntimeSecret, RuntimeFreegc. Not guaranteed by compatibility; track status in release notes.

Zero immigration would shrink Japan: by 2040 about 11 million workers are missing, threatening rural towns and pension sustainability. GDP would contract while mega‑corporations dominate, wages may rise for some but inflation and heavy debt would pressure the economy. Public services would cost more and shrink, with many small firms failing. The trade‑off: maintain social cohesion and a “pure” Japan at the expense of growth, pensions, and rural livelihoods.

Azure Linux 4.0 is Microsoft’s first general‑purpose Linux, a Fedora‑derived distro you can run on any Azure VM or via Marketplace. Built from upstream Fedora with declarative overlays, it uses kernel 6.18 LTS, dnf5, and an auditable supply chain with signed packages; FIPS 140-3 is in progress. It’s minimal (no GUI, distroless images) and now powers AKS, WSL, Databricks, and LinkedIn workloads, marking Microsoft’s move from internal hosting to shipping an externally usable Linux distribution.

South Korea is tightening online content controls under the 전기통신사업법, requiring internet communities and forums to scan all user-uploaded images and videos with AI censorship tools. Operators must supply their own hardware; government will not subsidize. Enforcement begins July 1, forcing small sites to bear hardware and software costs. Critics warn it could strangle small communities and chill free expression, arguing the law already covers CSAM and illegal filmmaking and now risks overreach into drawings, memes, and ordinary content. Past AI censorship examples—swimsuits, memes, and even math problems—fuel fears of political censorship.

WSL 2’s cross-OS file access gets faster: a May 2026 update gives each virtio device its own SWIOTLB DMA pool, removing shared DMA contention and speeding heavy I/O on Windows mounts (e.g., /mnt/c). It requires kernel Microsoft.WSL.Kernel 6.18.26.3-1 and WSL DeviceHost 1.2.29-0. To enable, set virtiofs=true in the [wsl2] section of .wslconfig, update to the latest pre-release kernel, and maintain at least 1 GB RAM with 64 MB SWIOTLB headroom. Virtiofs remains opt-in; Plan 9 over Hyper-V is still the default.
