Linux is gaining ground in 2025 as Windows declines and many users resist Windows 11. Across sources, Linux-based systems (including ChromeOS and Android) account for a growing share of end-user devices, with desktop Linux climbing from ~1.5% in 2020 to around 4–11% by 2025. Drivers include Windows 10's end of support, cost and privacy appeals, better hardware support, and Steam/Proton-enabled gaming. EU/UK governments’ digital-sovereignty moves also push adoption of open-source desktops. Overall, Linux is moving from niche to pragmatically mainstream for many users.

Cloudflare describes tackling Salt CM failures causing release delays. They built an architecture to decouple job results from Salt Masters by caching results on minions, enabling rapid triage (Phase 1). They then created Salt Blame, an execution module, to surface failed states and correlated commits/releases, providing before/after context (Phase 2). Phase 3 added chat-based, multi-data-center triage, reducing manual context switches. Phase 4 uses Prometheus/Grafana to measure root causes and feedback loops. Result: >5% faster edge releases and less toil; future plans include deeper Salt module integration and more automation.

Geoff Huston re-examines Starlink geolocation and ISP market shares after earlier anomalies in Yemen. He notes civil unrest can distort ad-based measurements: Yemen’s Houthi authorities ordered Starlink devices surrendered (April 2025) and later banned Google Ads on Yemen Net, causing ad volumes to plunge. Using Aden Net’s stable share as a proxy, he patches Yemen’s data to estimate bounds for Starlink and other Yemeni ISPs. Myanmar data remain chaotic due to ad blockers. He restores the original Starlink geolocation data for most countries, and reports a global Starlink user base of about 2.3 million, growing 0.8 million yearly.

Migration from GitHub to Codeberg/Forgejo: motivations, steps, and results. The author set up profiles, then migrated 45 repos using Forgejo’s “migrate from GitHub,” importing issues/PRs/wikis/releases via a GitHub PAT; fixed broken links with search/replace; updated remotes; stubbed moved repos with a script; ported CI to Forgejo Actions, considering energy costs and runner limits; rehosted the site with git-pages/Grebedoc since Codeberg Pages was in maintenance; overall, a weekend effort with a successful migration, mostly painless, with some anxiety but worth it.

CLAUDE.md onboards Claude into your codebase because LLMs are stateless; it should cover WHAT (stack, project map), WHY (purpose of components), and HOW (how Claude interacts, tests, builds). Claude often ignores it; keep a logging proxy to study behavior. Best practices: make it concise and universally applicable, ideally under a few hundred lines; use Progressive Disclosure by pointing to task-specific docs; don’t overload with code-style rules or every possible command; use deterministic tools (linters, formatters) instead of asking Claude to lint; avoid auto-generating CLAUDE.md. In short, it's a high-leverage onboarding artifact that should be carefully crafted.

Shadowing a hospitalist for a 10-hour shift, the piece portrays hospitalists as generalist coordinators who manage 8–10 inpatients, rapidly gathering data to diagnose and discharge, while deferring detailed interventions to specialists. Communication is mainly verbal; written notes are retrospective, causing information gaps and “manhunts” for details. In an HMO setting, compensation is fixed, so intrinsic motivation varies; high-agency clinicians can improve outcomes (e.g., earlier cancer detection) but aren’t rewarded differently. Observations cover emotional compartmentalization around death, nurse–doctor dynamics, reliance on tests over patient narratives, and challenges like poor cell reception and time perception.

To quiet a DIY Corsi-Rosenthal box, the author swapped a Lasko box fan for five PC cooling fans, enclosed in Recticel foam and a lid/shroud, powered via SATA. Performance: PM2.5 reduction similar to the Lasko version on low, slightly worse than the shrouded version. Sound: about 3 dB quieter at 50 cm, with noticeably less high-pitched noise and less tonal droning. The piece argues quiet operation increases usage, discusses basic fan-noise physics (loading/broadband noise, blade passing frequencies) inspired by Lighthill.

Langjam Gamejam is a 7-day hackathon (Dec 14–20, 2025) to design and implement a programming language and then build a game using it. Participants can work solo or in teams, use any language, engine, libraries, and technologies, and define what counts as a programming language and a game. Documentation is encouraged; prizes for the most creative submissions. Bonus points for a blog post about the language, game, and design process. Submit on Itch.io. © 2025 Austin Z. Henley.

This piece argues AI is being forced on people through search bars, OSes, and tools, driven by liquidity and billionaire profits rather than real utility. It calls for slow, organic adoption, rejects AGI as unnecessary, and favors software that actually works. If a model fails, researchers should refine it while users continue their work, and creators should be compensated rather than exploited. It rejects force-feeding the market and urges value-based, voluntary AI use rather than capital-driven push.

ESA's Copernicus Sentinel-1D has delivered its first high‑resolution images, covering Antarctica, Tierra del Fuego and Bremen. Launched 4 November, the 12 m SAR satellite downlinked data within about 50 hours, potentially the fastest radar Earth observation data delivery. The images—over the Antarctic Peninsula, Tierra del Fuego and Bremen—show unprecedented quality and rapid processing, with AIS helping detect ships. The scenes underscore glacier fragility (Thwaites and Pine Island) and sea ice, set against climate-change context highlighted at COP30 and in WMO findings.

llvm-mos is an open-source fork of LLVM that adds first-class MOS 6502 and related targets support. It enables modern development for classic 65xx-based machines, with a C/C++ frontend (Clang) and integrated 65xx assembler, IEEE-754 floating point, and freestanding C99/C++11 compatibility. It ships an SDK with target-specific code, a minimal C standard library, and ELF support for 6502, plus automation for tests, benchmarks, and packaging. It supports 20+ targets (including emulators) and can run on Godbolt; public discussion on Discord. Not affiliated with LLVM Foundation.

An in-depth guide to the Apple Desktop Bus (ADB) protocol, a 10 kb/s, host-driven serial bus for keyboards and mice. Each device has a 4-bit address and up to four 16-bit registers; the host uses Talk, Listen, SendReset and Flush. Initialization uses a reset and collision-based readdressing. Transactions begin with Attention, Sync, 8 data bits (4 address, 2 command, 2 register) and a stop bit; SRQ may be asserted during the stop window. Registers 0–3 hold data and device settings (address and handler ID). Keyboards and mice have standard and extended protocols; extended keyboards support left/right modifiers and LEDs. Timings are from Apple’s guide.

Modern cars are increasingly connected and collect data on driving habits, GPS location, telematics, and onboard sensors. This data may be shared with insurers, marketers, and data brokers, raising privacy concerns; GM was barred by the FTC from sharing driver data with consumer reporting agencies. Drivers should become aware of what's collected, check privacy labels (Privacy4Cars), and adjust settings to limit data sharing (e.g., Master Data Consent in Toyota, privacy options in Ford and BMW). Opting out can reduce features like navigation or roadside services. When selling, factory-reset and notify the manufacturer.

David Jasso uses Atlas Shrugged imagery to describe HP's decline from a 1990s Fortune 25 powerhouse to spinouts and splits. He notes HP's three core units and the "HP Way" culture. A 1997 consultancy warned of slower growth, yet leadership internalized doubt, shifting from winning to not losing. This mindset helped trigger Agilent spinout (1999), Fiorina’s tenure, the HP/Compaq merger, layoffs, Hurd’s cuts, the Autonomy debacle, and the 2015 HP/HPE split. Takeaway: belief in success drives morale and performance.
