Used Fable to port 65kLoC from Zig to Rust for $400. After Matt Pocock’s /teach Rust, I adopted a porting workflow inspired by Rewriting Bun in Rust: generate a porting guide, mechanically convert each .zig to .rs per PORTING.md and LIFETIMES.tsv, then fix compiler errors and get Bun’s tests and build to pass. A rewrite can be cheaper by treating code as a data problem: extract a representation (graphs/ontologies/UML), simplify it, then emit code in the target language. The post notes Fable’s data-flow tracing and a rune-terminal-editor concept, © 2026 Iurii Krasnoshchok.

Episode 59 of Inside Java argues that Java’s higher memory footprint is a strength, trading memory for fewer CPU cycles via moving garbage collectors, speeding up programs. Recorded at JavaOne 2026, the “Ask the Architect” episode features Nicolai Parlog and Oracle Java Architect Ron Pressler, discussing how Java trades memory for performance and the broader OpenJDK ecosystem.

HN Match is an AI-powered tool that pairs Hacker News “Who is Hiring” postings with “Who Wants to Be Hired” candidates. Each match is pre-scored with a signal-by-signal breakdown. The page covers a broad, global slate of onsite and remote roles—from Fastly, Sourcegraph, and Discord to Wikimedia, Boom Supersonic, and many startups—listing locations and salaries. Scores are precomputed from signals like skills, domain, seniority, and salary overlap.

Apple says new forensic findings from ex-Apple engineer Chang Liu’s MacBook bolster its OpenAI lawsuit and push for expedited discovery. The initial analysis allegedly shows Liu downloaded an Apple circuit schematic and used it at OpenAI, and that he and others were aware of his unauthorized cloud storage access. He allegedly instructed destroying evidence and used a tool that shares a name with an internal Apple app. He reportedly ran a March LTspice simulation with the schematic, and discussed an AI agent learning to run LTspice. Apple also seeks the Mac mini involved.

Mike Dodds argues that formal specifications for systems largely don’t exist and are costly to produce. A formal spec should be precise, easy to reason about, encapsulated, agreed, and stable; once a good spec exists, verification becomes feasible, as seen with compilers, cryptographic libraries, parsers, and microkernels. Yet most domains lack such specs, and informal artifacts (prose docs, slide decks, user stories, tests) proliferate and conflict. PDF epitomizes the problem: no consensus formal spec. Galois’s DARPA PDF work failed to yield a normative spec. With AI, proofs may be cheaper, but we should prioritize partial specs and tests over specifications.

Philip Wadler surveys Jaron Lanier's argument that AI systems like GPT-4 are advanced mashups of human-created text and images, not independent minds. He advocates "data dignity"—treating data as labor, paying creators, and channeling platform fees to those who produce valuable content—to curb online capitalism's downsides and addictive targeting. The post argues this approach could ease AI adoption, enabling new forms of work (e.g., AI-assisted tree trimming) and broader innovation, since models improve only with better inputs.

Analytical critique of Ed Zitron’s AI-skeptic predictions. The author argues Zitron’s major forecasts—OpenAI/Anthropic collapse, plateaus in model progress, and the demise of Meta/Google/Microsoft—have repeatedly failed through 2024–2025, while his reasoning rests on cherry-picked data and flawed industry understanding (e.g., MAU misreads, Raghavan critique). Zitron’s style relies on anger and gish gallop rather than solid evidence, and defenders often ignore refutations. The piece compares Zitron to futurists, notes calibration issues and predictive scoring (Brier score), and calls for more rigorous evaluation of claims.

Found a Tektronix TDS7104 at a flea market; after a dim display and CMOS battery error it was refurbished. Common failures include dead CMOS/PowerPC NVRAM batteries, hard drive, and leaking capacitors. Steps included imaging 6 GB hard drive, replacing the CR2032, and correcting display color settings. Avoid front-panel removal if possible. Disassembly was 32 screws. An SSD upgrade with 64 GB mSATA failed due to Windows registry; reinstall from scratch with Windows 2000 Pro via a USB stick using Plop Boot Manager. Installed Tektronix firmware, fonts, and required drivers; license features unlocked. Result: a working TDS7104 with SSD.

Simon Willison reports finding in the OpenAI Codex (now ChatGPT) cache a codex-primary-runtime folder containing a full Python and Node.js, plus native binaries for Poppler, Git, and LibreOffice. The documents plugin folder includes 'skills' that tell Codex how to locate and use these binaries, revealing substantial local runtimes cached by Codex/ChatGPT.

After subscribing to his monthly newsletter, Bruce Schneier receives many auto-generated one-line compliments from random Gmail addresses that never subscribed. The messages are likely AI-generated scam attempts, though the exact objective is unclear. Theories include pig-butchering-style social engineering to prompt replies; laundering or validating email lists; evading fraud detection; and harvesting data such as IPs, timing, and geo info. Readers discuss possible mechanics (SPF/DKIM, aging accounts) and motives, but no definitive conclusion emerges.

Atlas is World Labs’ omni world model for spatial intelligence. A multimodal autoregressive diffusion transformer trained from scratch to handle text, images, video, and 3D, grounded in a shared 3D spatial context. It can generate, reconstruct, and simulate worlds: camera-controlled generation (pixel-perfect views and long 1440p video), sparse-input 3D reconstruction (depth, point clouds, 3D splats), and space-time simulation for VFX and robotics with Real-to-Sim workflows. Atlas scales with compute and is available in early access for partners.

Doug Barnes explains the Bendix 70 coaster brake hub and how coaster brakes work. Coaster brakes, dating from the 1890s and popular mid‑20th century, are sealed in the rear hub. Pedaling forward drives the wheel; pedaling backward moves a clutch on the drive screw, expands brake shoes, and slows the bike. Advantages: simple, low maintenance, weather‑proof, cable‑free, usable for riders with limited hand strength, and compatible with some gears. Disadvantages: hard to feather, occasional wheel lock, not compatible with rear derailleurs, and heat on long descents. He demonstrates maintenance on a 50‑year‑old Columbia bike.

The 36-team league phase creates dense internal clusters that can penalize a group’s combined chances. Example: Napoli-Benfica-Chelsea-Ajax-Qarabağ form 9 of 10 internal pairings in UCL 2025-26. A single symmetric graph on 36 vertices, C(36; ±{1,4,10,17}), can remove this risk: vertex-transitive, 8 opponents per team (2 from each of 4 pots), and minimal clusters. But country rules prevent a valid assignment; two tweaks fix it: A) raise max same-country opponents to 3, or B) split large federations into subgroups to permit cross-subgroup same-country play. UECL needs no change. 2026-27 draws show similar density; the symmetric-graph approach would prevent such clusters.
