Zig’s std.Io.Threaded is a thread-based Zig IO implementation that enables cancelation of blocking syscalls. It uses a shared cancellation flag and POSIX signals to wake a thread (EINTR), retrying or unwinding; Windows uses NtCancelSynchronousIoFile. Cancelation becomes error.Canceled, with errors erased by type-erased IO interfaces. It distinguishes io.async (may run concurrently) from io.concurrent (must run concurrently) and backs this with a thread pool, only spawning new OS threads when needed. It avoids pthread_cancel drawbacks and contrasts concurrency vs parallelism and the language/kernel boundary.

Tom Overton's John Berger: From Life is a vivid, highly subjective biography that situates Berger's Ways of Seeing within a broader political project. Tracing his London upbringing, exile in Switzerland and France, and dialogue with the past, it shows how Berger treated each work as a portal between time and space and insisted looking is a political act. Overton, who curated Berger's archive for the British Library, writes with warmth and self-doubt, acknowledging his subject's contradictions. The result is a portrait of a critic who continues to speak after death through lessons, videos and reissues.

lcamtuf's Getting silly with C playfully probes extreme C tricks and compiler quirks. It surveys four topics: (1) function definitions and the hazards of forward declarations and odd void parameter syntax; (2) operator precedence and bizarre uses of attributes, typedef quirks, and GNU extensions; (3) goto statements, including computed jumps (goto *ptr) and comma-separated expressions; (4) counting and adding with unusual constructs like empty unions and zero-sized types, revealing surprising results in parameter evaluation and pointer arithmetic. A follow-up thread clarifies the actual rules and GCC quirks behind these tricks.

B-right/V R2 is the TRON BTRON3 OS for IBM-PC/AT compatibles, released 1999 by Personal Media. It embodies the network-interface computer model: small footprint (486DX, 16 MB RAM) but full word processing, graphics, spreadsheet, scripting, e-mail, browser, and a hypertext filing system. It introduces a true TRON Multilingual Environment with up to 31 character planes (≈1.5 million chars); no official TRON character set exists, with a Character Resource Center to add more. A Character Search Utility aids kanji lookup. It adds PPP dial-up, FTP, e-mail, and peripherals; future work: expand language layers and vertical scripts. Freeware lists online.

Claudette is a Claude Code skill that post-processes Claude responses by sending them through the Gemini CLI to render plain-English output. It aims to strip Claude’s TED-talk voice and present human-friendly translations. The README discusses Claude’s tendency to sound like a hypey engineer, provides a before/after example, and explains the workflow: save Claude’s reply to a temp file, pipe through Gemini, print Gemini’s output. It offers install steps for Gemini CLI (npm install -g @google/gemini-cli), usage of /debuzz [mode] [text] with modes colleague, manager, director, and notes MIT license.

Rafal Cymerys describes becoming AI-blind: he notices AI-like traits in work documents—design briefs copied with Claude-specific phrasing, marketing decks mixing strategy with technical gibberish, and verbose tech specs that read like internal LLM reasoning. He argues humans can spot low-effort AI-generated text by patterns, language, and overhyped breakthroughs. This overload creates banner blindness, dulling attention and slowing him down instead of boosting productivity. He suspects the same AI meant to help is hurting focus, prompting him to filter content and even daydream about AI cues.

NVIDIA AI announced that its general-purpose coding agent scored 100% on the ARC-AGI-3 interactive reasoning benchmark, completing all 183 levels across 25 public environments without any instructions, explicit rules, or stated goals. NVIDIA AVO reportedly continuously inspects, plans, implements, and evaluates using memory, tools, and feedback to sustain progress on long-running tasks rather than restarting with each model context.

Author argues for the AI;DR stance: don't rely on AI outputs without human review. AI-generated materials (Slack messages, decks) often over-engineered, erroneous, or filler. Citing Niklas Gruhn’s Don’t be a meat proxy, the post says readers must read, understand, validate, and rewrite AI outputs in their own words to prove they did the work. Warns against handing off thinking to AI and stresses doing the job you’re paid for to avoid waste.

Cassandra 6 aims to enable ACID transactions and is tested on a 3-node cluster across four modes: none, BATCH, Lightweight Transactions (LWT), and Accord. Plain updates offer no isolation; BATCH is atomic per partition but not across partitions, with timestamp ties causing cross-partition anomalies. Read-modify-write with BATCH is unreliable. LWT provides per-partition atomic compare-and-swap but cannot span partitions, and cross-partition LWT fails. Accord enables true ACID across tables and partitions via EPaxos-like consensus, but some cross-partition tests show anomalies and a bug confirmed by Apple. Overall, progress toward ACID in Cassandra 6 is promising but experimental.

DuckDB v2.0 replaces its PostgreSQL-derived parser with a PEG-based parser to ease evolution and runtime extension. The new parser handles tokens, parses into a generic parse result, and transforms into DuckDB’s AST, preserving the DuckSQL dialect. It removes parser bottlenecks, supports full DuckSQL, and uses packrat parsing to avoid exponential backtracking. Extensions can add grammar rules and transformers, enabling new syntax (e.g., expression statements, CONNECT, and PIPE SQL) while reusing existing parsing rules. The design aims for runtime extensibility without altering core execution.

Rama 0.4 adds system-configured proxies and PAC support, introducing a SystemProxyLayer to honor system proxies and a PAC runtime via rama-pac and a WASM-based JavaScript runtime (rama-js) for isolation. It expands networking with ttRPC and gRPC macros, adds HAR WebSocket export with streaming and a new --har CLI option, and enables PAC script generation/evaluation in the CLI (including a REPL). Other updates include faster protocol peeking, improved HTTP peeker logic, Apple Network Extension enhancements, and support for multiple PAC routes and updated proxy DB. See CHANGELOG for details.

An author shows how an expired e164.arpa delegation let them hijack ENUM routing for Saint Helena, Diego Garcia, and Ascension Island. By renewing ns.enum.org.uk, they controlled 0.9.2.e164.arpa, 6.4.2.e164.arpa, and 7.4.2.e164.arpa, steering queries to a personal SIP server and potentially MITM-ing calls. They logged hundreds of thousands of ENUM queries—mostly from the US—revealing phone numbers, times, and source IPs. After reporting to the UK NCSC, ownership was transferred to them and logs were deleted. The episode highlights governance gaps in e164.arpa and ITU procedures.

Ray Newman argues we’re already living in a near-future, cyberpunk present, where mundane daily life is saturated with AI, robots, drones, facial recognition, and climate chaos. By collaging headlines—from IV drip clinics in malls to AI-generated music, robot parks, and police drone ops—he shows how technological advance quietly unsettles culture. He asks how to write credible sci-fi in such a world, noting our resilient adaptation and the ease with which the extraordinary becomes ordinary.

Olympian Jenny Simpson says her running career is over after a sudden cardiac arrest in June revealed she has Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC), a rare inherited heart condition. After CPR and life-support at Duke Hospital, she recovered and is at home in Colorado with ongoing care. She notes that returning to running is dangerous and that “That chapter has ended,” but she is continuing in the sport off the track as Fleet Feet’s chief running officer, helping others, and asks fans not to apologize but to celebrate her being here.

Martin Kleppmann argues that Yes/No/Cancel labels are inherently ambiguous, since they depend on context and often imply two questions at once (e.g., save/discard or quit). Through examples of close dialogs, he shows how users can’t tell which button will lose work. He cites Apple guidelines favoring descriptive verbs like "Save" and distinct danger/ safety cues, and encourages designers to avoid negative framing and relabeling to improve overall usability.

Progress in large language models is twofold: higher ceilings and cheaper floors. The article shows that the cost per task for reaching a given intelligence level has fallen ~56x in six months (from ~$1.22 to ~$0.022), with a 100x drop expected within about a year as frontier models are replaced by cheaper ones. The Artificial Analysis Intelligence Index tracks capability, and the Pareto frontier reveals rapid commoditization, especially via open-weight models. Cheaper intelligence expands use cases (census-like reading, monitoring) even as tasks scale; Jevons paradox implies total spending can rise. System design should route tasks dynamically across frontiers.

Kodak’s Lunar Orbiter camera began as a classified WS-117L satellite system. It exposed 70mm film in orbit, developed it onboard with Bimat web technology, and transmitted images via a flying-spot scanner to Earth. The E-1/E-2 tests pursued multiple resolutions, with E-2 using a steerable nosecone. After a launch failure and shifting priorities, readout work waned in favor of recoveries, but NASA, the NRO, and the CIA later adapted Kodak’s system for Lunar Orbiter to map the Moon for Apollo landing-site selection. The design bridged military reconnaissance and space exploration.
