Amiga-derived AROS has been ported to boot bare-metal on the Raspberry Pi (32-bit and 64-bit), making a 64-bit Amiga-compatible OS on ARM. AROS already runs on x86, PPC, 68k Amiga, and RISC-V, and this Pi port extends that cross-platform lineup. Previously Pi support ran under Linux virtualization; the bare-metal build offers a lighter, faster boot. ARM software is still evolving; the Pi3 is the current target, with discussions of Pi4 and Zero2W support. A demo video by Dan Wood is linked.

Hacker News In Uncompromised Detail recounts the site’s origins as Startup News (2007), its hacker ethos, and technical lineage from Arc to SBCL. It explains posting types (link vs text; Ask HN, Show HN), voting/karma, and a front-page ranking system. It covers moderation (dead posts, shadowbans, second-chance pool), how editors balance YC independence, and job posts. It maps search/API history (ThriftDB, Algolia, Firebase), demographics, name-color rules, holiday themes, and notable threads like the Dropbox comment. The piece also notes governance and anti-gaming measures.

An Amazon Fire HD 10 kept rebooting the author’s Home Assistant kiosk. To fix it, they spent $114 on the tablet and about $266 on four AI models (Kimi K3, GLM-5.2, GLM-5.3, Claude) across months. Kimi K3 found an unpatched kernel bug; GLM-5.2 diagnosed reboot bugs; GLM-5.3 completed a root, removed all Amazon packages with reboot/shutdown rights, and disabled OTA machinery. The result: a functioning, minimal tablet that runs the kiosk with no Amazon software. The author notes rooting own devices is legal under DMCA exemptions and reflects on the ethics and economics of renting security through AI.

Complex systems (healthcare, transport, power) are intrinsically hazardous; safety emerges from layered defenses—technical, human, organizational, and regulatory. Catastrophe requires multiple concurrent failures; most latent defects are continually present, with degraded performance common. Systems run in degraded mode, kept functional by redundancies and practitioner adaptations. Root-cause blame is misleading: accidents arise from multiple, interdependent factors, not a single cause, and hindsight biases distort post-accident analysis. Practitioners are both producers and defenders, making gambles under uncertainty. Safety depends on continuous, system-wide adaptation, calibration of hazard awareness, and recognizing the edge of the envelope.

Zed A. Shaw argues that authoritarianism is deeply embedded in software development, especially open source. He defines it as deference to authority granted or taken without enthusiastic informed consent, and separates leadership from community dynamics. He avoids labeling all as fascist, viewing fascism as a subset of authoritarianism. The essay analyzes how communities often protect leaders and punish dissent, citing the Python ecosystem's 2012 PyCon Code of Conduct case and Steve Holden's behavior, plus the 2013 dongle incident, to show unequal enforcement. It urges evaluating projects by informed consent and, if needed, leaving. A preview of the next essay.

Terence Eden argues CSS units are perceptual, not literal: 1px and 1cm vary by display and distance. He experiments with the ch unit to set readable text width (e.g., --width-content: min(75ch, 100%), main { max-width: var(--width-content); }), and uses ex for vertical gaps. He favors relative measures alongside px and notes there’s nothing inherently wrong with any unit. The post includes reader comments and mentions a voluntary paywall.

An old draft arguing for a modern relational query language that improves on SQL by adopting clearer syntax, better parsers, and a functional, 4GL-like style that describes what data to retrieve rather than looping. The piece advocates stronger defaults, more informative query planners, and richer user-defined types and domains (as in PostgreSQL/Oracle), plus sum types, discriminated unions, and pattern matching to express complex schemas (e.g., IBM i stack frame types) more concisely. It also proposes multi-type foreign keys to avoid duplicative join tables and gives examples showing how a discriminated-typed schema could simplify queries and tooling. The tone invites discussion.

Harnesses are software environments that let an AI model operate as an agent. They provide four components: a system prompt (instructions), tools the model can call, an agentic loop governing how the model acts (search, analyze, decide, loop), and a translation layer to work with various models. End users can own and customize harnesses (e.g., Pi via command line, Lefos via email). Open-source, neutral harnesses like Pi, OpenClaw, OpenCode, Hermes empower user agency by comparing models, tools, costs, and sessions. Earendil promotes neutral, open harnesses to expand human agency and avoid lab lock-in.

Researchers from Kaspersky Securelist uncovered the first Android malware targeting automotive head units. Discovered in June 2026, the multi-stage threat rides on the head unit’s TWCore updater (a legitimate system app) to install a UI-less dropper JarService, which decrypts payload and loads stage 2, then a stage 3 reverse-proxy loader named zhima. Its aim: ad fraud and a proxy botnet. The infection chain uses MQTT to push APKs, with installNotExists enabling installation of non-present apps. Attributed to MoYu Group/BADBOX. This is the first malware on car head units; vehicle IoT protection is now needed.

Adam Conway tested Qwen 3.8 27B on a Lenovo ThinkStation PGX with 17 GB VRAM, pulling ~50 tokens/s using SGLang/NVFP4/DFlash2. He tasked it to reverse-engineer a commercial app’s license check. The model refused jailbreak prompts, audited the verification, then, via static analysis, reconstructed the vendor’s public key from the binary and produced a working bypass offline, without running the app until the end. It demonstrated that a local 27B model can perform high-level reverse engineering on real software, highlighting privacy and threat-model implications, with caveats about representativeness.

Sydney Marathon medal design mistakenly shows Munich’s Allianz Arena instead of Sydney’s Allianz Stadium. About 40,000 runners are expected on August 30. The other face features artwork by Ambrose Killian, who says he wasn’t responsible for the other artwork. The blunder echoes last year’s Great North Run mix-up. Sydney joined the Abbott Majors series in 2024; Cape Town will join next year. The BBC sought comment from organisers.

Henry Stanley argues that the peptide market is saturated with gray-market suppliers, but buyer experiences are undermined by AI-generated, fake reviews and bot-driven sites. He shows how Qingdao Sigma looks legitimate with TrustPilot-like praise that is actually non-existent, and how CompoundTalk hosts AI-authored threads and suspicious registrations. The piece reveals a Potemkin online ecosystem designed to feed LLMs, not humans, urging readers to detect AI-generated content (e.g., with Pangram) and remain wary of peptide claims.

Overview of the Institute for the Study of the Neurologically Typical (ISNT), a parody/anti-neurotypical site by Erik Engdahl. It hosts a mirror of the vanished isnt.autistics.org and coins “NT” (Neurotypical Syndrome) as a satirical, fictional disorder lampooning neurotypicals’ social rigidity and mistaken views of autism. Content is humor, not literal truth, and the author frames autistic experience as valuable. The site invites papers and observations in “Current Research” and includes sections like What Is NT?, How Common Is It?, and Papers and Abstracts. Last updated 2002; mirrored from a 2010 archive.

Wi‑Fi 8 is not chasing speed but reliability. The IEEE aims to improve real‑world throughput, latency, and MPDU loss in crowded homes, without increasing maximum data rate from Wi‑Fi 7. New features include DRUs to boost effective transmit power, interference‑mitigation pilots, unequal modulation per stream, new MCS, P‑EDCA, and exclusive non-primary‑channel use to reduce waste. It also targets seamless roaming and better multi‑AP coordination. Finalization is planned for May 2028, with early devices in 2028. If you don’t have multi‑gig broadband, waiting for Wi‑Fi 8 may be worthwhile rather than upgrading to Wi‑Fi 7.

Historically, JITs were hard; this post demonstrates building a fast JIT in pgrust that compiles in ~5μs, enabling JIT for all SQL queries. Using AI, the author creates a copy‑and‑patch assembler pipeline (stencils) to generate ARM64 code for a simple regex engine (b(an)*). The code is loaded with mmap, made executable, and called like a normal function. An interpreter, handwritten regex, and JIT are benchmarked; JIT matches or exceeds hand-written in some cases and consistently outperforms the interpreter, with 15–20x or more speedups. AI lowers the barrier to JIT; star the project on GitHub.
