Scott Hanselman debugged a 10GbE network that stayed slow for SMB writes to a six-disk NAS. Isolated tests showed the bottleneck was the Windows NIC, not the NAS or SMB. The Intel E610-XT2 had many ReceivedDiscardedPackets due to small default receive buffers. Increasing to 4096 cleared discards and raised iperf throughput from ~1.33 Gbit/s to 5.15 Gbit/s. Disabling IPv4 Large Send Offload lifted it to 7.03 Gbit/s. Real SMB writes then hit ~350 MB/s (~2.8 Gbit/s). Lesson: test the network stack first; LSO can hurt throughput on some setups.

Linux desktops can greatly improve laptop speaker quality using EasyEffects, a PipeWire-based audio processor with plugins from Calf, MDA.LV2, and GStreamer. It allows per-stream effects and comes with presets (often generic) that can be installed from distros or Flatpak. It can be accessed from the system tray, run at startup, and integrated into KDE/GNOME sound settings for easy preset switching. While results vary by laptop and user, the author argues EasyEffects should be bundled by distros and OEMs, as tuning can significantly improve tinny laptop speakers without much CPU overhead.

An in-depth look at the global fight over sand, a finite, essential resource for concrete and countless products. As demand for development drives a $70 billion industry, illegal sand mining fueled by mafias spreads across India, Indonesia, and elsewhere, triggering killings, corruption, and environmental destruction—from Raipur Khadar to Thane Creek. Despite court actions and occasional raids, enforcement is weak and violence persists. Activists push for accountability, but the core problem remains: supply is finite while demand grows with rapid urbanization.

China warns that a barrier lake formed by an ice–rock avalanche on the Nepal–China border remains high and overflowing, with a risk of breach. Nepal and China continue monitoring the lake and downstream river levels; residents downstream are urged to stay vigilant and prepare for emergencies. The embassy did not specify the lake’s size, volume, or breach timeline. Earlier reports said the barrier lake near the confluence of Chhochen Khola and Purepu Tsangpo had breached; Nepal also faces floods and landslides.

The author tried musl as a self-contained libc for containerized Bifrost and Rust projects, hoping for performance gains. He found musl's allocator disastrously slow, even on 4-core VMs, and notes that swapping in mimalloc or jemalloc doesn’t restore performance to glibc levels (musl with mimalloc ~26% slower). Other memory routines are also slow. Consequently, he’ll keep musl for small projects but will not offer musl as a prebuilt option in performance-sensitive Bifrost builds.

Washington designated Autistici/Inventati (A/I Collective) a Specially Designated Global Terrorist, marking the first time the 'material support' logic targets infrastructure rather than operatives. The sanctions are expected to de-risk A/I by forcing banks, hosting providers and payment systems to sever ties, potentially expelling the group without Italian court action. The move reframes counterterrorism to include infrastructure as an object of sanctions, with implications for European allies and democratic safeguards. It emphasizes deniability via intermediaries and raises questions about balancing security needs with civil liberties and legal standards.

Verschlimmbesserung, a German term for an attempted improvement that makes things worse, explains why software updates backfire—moving buttons, renaming menus, or shipping “better experiences” that solve trivial problems—driven by metrics. As Goldratt warned, how you measure a team shapes its behavior; if updates chase churn or shipping, they may neglect real product value. Stability is valuable; frequent reinvention can harm usability. The piece argues for recognizing when not to ship and embracing stability as a feature, naming this phenomenon Verschlimmbesserung.

Despite being among Africa's most endangered carnivores, African wild dogs are the focus of a major conservation effort. The Endangered Wildlife Trust relocates dogs across reserves—often Mozambique to South Africa—to form genetically diverse packs, using sedations, enclosures (bomas) and tracking to expand habitat. The article follows three sisters moved to Welgevonden and later paired with males elsewhere; one dog died from capture stress. Yet the program has expanded habitat by about 1.5 million hectares and added 30 packs. By 2025 there were 150 puppies; total wild dogs ≈6,600 with 700 breeding pairs.

The piece argues GUIs should be fully keyboard-driven and that keyboard nav is not a solid reason to favor TUIs. GUIs can be more capable, but many GUI apps lack complete keyboard accessibility. Citing GNOME guidelines, it claims every action should be keyboard-accessible and navigation should cover the whole UI. The author describes building Klisi with broad keyboard shortcuts, concluding keyboard navigation is feasible and enhances UX. Takeaway: don’t compromise UX—strive for intuitive, full keyboard navigation in GUI apps.

Dactyl provides a cross‑platform SwiftUI renderer that runs in the browser via a Wasm port of an iOS simulator. It reimplements SwiftUI and many Apple frameworks; apps are built to Wasm and run through a base SwiftUI runtime with per‑app side modules. The browser host draws via Canvas2D, while on Android a Jetpack Compose host renders native widgets through JNI. The engine is continuously refined by automated agents comparing frames against the real simulator. Describe an app and see it built live in your browser.

htmx 4.0.0 released after eight months of work. Major changes: explicit attribute inheritance by default; standardized event names; history no longer caches in localStorage; moved from XMLHttpRequest to fetch(). Key features: morph swaps and the <hx-partial> tag. Expanded extensions (hx-preload, hx-download, hx-history-cache, hx-alpine-compat) plus streaming options (hx-sse, hx-ws, hx-multipart) and the htmax bundle. Upgrading aided by a tool; install via CDN/NPM. 2.x remains the latest until early 2027. Release date: 2026-08-28.

Author benchmarks Qwen3.8-27B (Q4_K_M, 17GB) running locally on a Mac Studio M3 Ultra. It trades speed for better per-answer token economy: ~14 tok/s vs qwen3.6's ~28.6 tok/s; ~1,000 tokens per answer vs 2,000-3,300 tokens for 3.6. 1-bit quant (6.7GB) runs at ~309 tok/s but can't commit to an answer; good for trivia, not tool use. RAM needs vary by quant: 16GB for 1-bit/2-bit, 32GB for Q4, up to 96GB+ for BF16. Run via Ollama; update llama.cpp; 262k context; vision works; it's a solid local alternative for background tasks.

Z.ai announced GLM-5.3 is now open-weight, described as their most capable model for agentic coding and cyber defense, available to download, run, and customize. Weights are on Hugging Face and a tech blog is linked. Reactions note a license shift from MIT to a semi-non-commercial license (similar to Kimi, MiniMax, Qwen). Unsloth AI praises the release and mentions GGUFs for local use.

OSS embargoes no longer buy time: even a bug rumour can seed autonomous exploits. Madhavapeddy details releasing a cohttp 6.3.0 fix and seeing probes within minutes, with attackers potentially exploiting before public patches. He outlines three responses: 1) private patching with a web-of-trust; 2) abandon embargoes and ship continuously via automated releases; 3) proactive protocol-layer protections and rapid mitigations. Also calls for better packaging, triage tooling, and research into antibotty defenses to raise defender throughput.

“ Weird” began as Old English wyrd, meaning fate. In Middle English, French/Latin words for fate entered English, and wyrd faded except in the north where Scots kept it as weird and tied it to the Fates. The phrase “weird sisters” in Macbeth (from Holinshed) helped fix the sense of uncanny; early printings show the form “weyward.” Theobald later standardized the spelling. From the Romantic era onward, weird broadened from fate/uncanny to “odd” or “unusual,” and today it’s one of English’s most common words.

ALMA's longest-baseline observations of Betelgeuse reveal an irregular, bubbling surface with hotspots. The red supergiant, about 600 light-years away and ~800 solar radii, was imaged at ~7 milliarcsecond resolution in 2023. The atmosphere averages ~2300 K, with two hotspots (NE and SW); the brightest is ~800 K hotter than surrounding gas. These features trace convective motions and shocks as hot gas rises. The northeastern hotspot persisted from 2015 to 2023, implying a lifetime of seven years, longer than current convection models predict. Betelgeuse’s shape varies by ~6% and its environment is clumpy (SiO/CO). A close companion is unconfirmed.
