OpenStrike is released: a single-player, Counter-Strike–shaped FPS running on a 2004 PSP (333 MHz, 32 MB) with a locked 60 FPS. Built with a Rust engine (OpenStrike-core + Pocket3D renderer) for physics and rendering, and a JavaScript layer (TypeScript rules.ts, hud.tsx) running on QuickJS via PocketJS; the JS controls gameplay rules and UI. Maps are GoldSrc BSPs baked into .p3d via pocket3d-cook, using precomputed PVS, baked lightmaps, and 16-bit vertices. The product ships as one EBOOT.PBP with both PSP and desktop builds; it's open-source at pocket-stack/open-strike. Demonstrates web-stack ergonomics for embedded hardware.

LBSE runs SVG through WebKit’s HTML/CSS renderer by moving from per-element layers to conditional layers, aiming for hardware-accelerated SVG. In 2026, renderers get a layer only for intrinsic reasons (opacity, clipping, masking, filters, blend modes, 3D transforms, perspective, z-index). Most shapes without 2D transforms no longer use a layer; transforms fold into paint, though transformed containers keep a layer. SVG fields moved to a lazy SVGData, and transforms cached on renderers. DOM order preserved for non-layer content; composited content among siblings without layers remains problematic and will be addressed next. Igalia funded LBSE work; goal: performance via HTML/CSS machinery.

Argues OSS is not immune to monopoly; as projects grow, leadership can resemble monopolies, making forks impractical. To keep ecosystems healthy, break monoliths into smaller, interoperable components using standard protocols, as UNIX did. This modular approach should be applied across the stack to prevent “too big to fail” dynamics. Monopolistic tendencies may be an emergent feature of human organization, not just capitalism, so fragmentation and interoperability are broad remedies.

An abuseofcats.com public service announcement warning against misusing the Unix cat command (cat(1)). It shows that piping a single file through cat can spawn needless processes and that cat should be used for concatenating files. It promotes using other tools and redirection (grep -v '^#' to ignore comments, wc -l < file, head -n 5 file, awk, sort) for common tasks, illustrated with playful ASCII cats.

A software engineer laments that AI-generated code has turned almost every aspect of software work into 'slop'—PRs, docs, reviews, roadmaps—making the craft feel sloggy. Opting out isn’t viable; interviews now probe AI stance, and most teams rely on AI daily. Some hope for niche, non-AI communities (e.g., Zig), but broad impact seems unavoidable, even with big players releasing AI-assisted software. The piece ends without a conclusion. The author notes his own site is hand-written and seeks sanity amid the trend.

Isomorphic Labs' IsoDDE is a unified AI-driven drug-design engine that advances beyond AlphaFold 3. It more than doubles AlphaFold 3’s accuracy on hard protein–ligand structure generalisation benchmarks, predicts binding affinities with higher accuracy than many physics- and deep-learning methods at lower cost, and can identify novel, ligandable pockets from sequence alone. IsoDDE handles induced fit and cryptic pockets, including accurate antibody–antigen interfaces (CDR-H3) and a cereblon cryptic site example. It enables rapid in silico drug discovery across diverse modalities, accelerating design while collaborating with Google DeepMind.

The article explains that 'Disk Not Ejected Properly' means macOS lost track of a storage device, usually due to a USB hiccup rather than data loss. It distinguishes mounting, unmounting, and ejecting; ejecting with IOKit discarding objects is when the device is no longer visible. It uses logs to illustrate differences between graceful unmounts and physical detachment, including cases where a device briefly disappears and reappears after reboot. Troubleshooting: try a different cable/port/hub, erase or replace failing drives, and monitor backups; recurring issues may require help via CCC knowledgebase.

Texas Attorney General Ken Paxton secured a court order to lock the domain motherless.com after Kick Online Entertainment refused to implement Texas’s age‑verification law. A writ directs Verisign to place the domain in a registry lock; Kick can reclaim it only by posting a $9.14 million bond and proving compliance with age verification and civil penalties. The move sets a precedent for enforcing age‑verification laws against foreign operators and shows Texas can act beyond its borders to protect children.

The article shows building static search trees (S-trees/S+ trees) to achieve high-throughput searches on sorted 32-bit data, outperforming binary search. It compares baseline binary search with Eytzinger layouts, uses hugepages, 64-byte cache-aligned nodes, and various memory layouts. It optimizes find with linear, SIMD (auto-vectorized, trailing zeros, popcount) and manual SIMD, then improves search via batching, prefetching, and pointer arithmetic, including interleaving batches. It covers node size (B=15 vs 16) and prefix partitioning/overlap. Result: 1150ns/query for binary search reduces to ~27ns/query with interleaved batched S-tree—about 40x faster; partitioning helps less on large data. Future work: interpolation search, packing, range queries, etc.

WIRED reports that the CDC downsized its Cyclospora outbreak-response lab from 11 to 3 staff amid sweeping 2025 layoffs, risking slower outbreak investigations. Former lab head Joel Barratt says responses will be “greatly diminished” due to reduced personnel. The CDC says the Cyclospora lab was not affected by cuts and continues coordination with FDA and states, even as Cyclospora cases climb (thousands nationwide, including 4,300+ in Michigan). The article notes the agency is stretched by other crises, such as Ebola in Congo and multiple U.S. outbreaks.

Union Pacific is tackling rail heat by painting sides of rails white to reflect sunlight, lowering surface temperatures by about 20 degrees. Using a high-rail truck with a paint sprayer, the program began in high-heat areas last year as part of Safety, Service and Operational Excellence. The technique, borrowed from European rail practices, complements maintenance and inspections to reduce thermal misalignment and derailment risk. UP notes no other U.S. railroad is doing this; the approach exemplifies its safety culture and contributed to its best-ever derailment rate in 2025.

Topcoat is a batteries-included full-stack Rust framework for building web apps. It renders markup on the server by default, letting components run async and query databases directly, removing the need for a separate API. Client interactivity can avoid extra round trips, as Rust expressions compile to JavaScript for the browser. When updates require the server, server-rendered shards re-render and swap HTML. It uses the view! macro for templates, supports module-based routing inferred from code, asset bundling, built-in Tailwind, fonts and icons, and a signal-based client runtime. Early-stage with breaking changes.

US grocery growth is slowing. NielsenIQ data show negative unit growth starting mid-2025, masked by price increases; by early 2026 units were down about 2% while prices rose 2–3% YoY. Causes include higher grocery prices, broad inflation, rising gas costs, SNAP benefits cuts, and tight disposable income. Bain’s Consumer Health Index shows cautious spending among lower- and middle-income households. Many shoppers are trimming baskets (28%), trading down (56%), buying fewer items (49%), or using more coupons (44%). Value-focused retailers gain share; firms should sharpen value with precise pricing, promotions, loyalty, and private brands.

Kaiser Permanente nurses who advise and triage patients say AI and intensified workplace surveillance threaten patient care. They report managers scrutinizing call times—often under 15 minutes—and software that predicts productivity and scores empathy and tone. Nurses say time pressure forces them to rush or withhold compassion, even in cases like a suicidal patient, risking safety. The California Nurses Association is bargaining with Kaiser over AI use; lawmakers are weighing bills to regulate automated systems at work. Kaiser says AI is used responsibly with human oversight, prioritizing safety and privacy.
