Colorimeter 3nh CR4501 RAL Hack adds on-device display of the closest RAL Classic color after measurement. Everything runs in the browser via WebUSB; no data leaves your PC and it’s fully reversible. The tool walks you through entering update mode, backing up, flashing, and testing. Works best in Chrome/Edge; Windows requires WinUSB via Zadig. It repurposes 216 RAL tones (three measurements each) with ~0.08 ΔE repeatability; worst 0.50. You can generate a custom firmware from your own deck using the Python tool in werkzeug/. It’s a weekend project with no warranty; use at your own risk.

Rust's five teams adopted an LLM policy for the rust-lang/rust monorepo. It is not an official project-wide stance and does not apply everywhere. It aims to curb issues from LLM use—polished PRs masking effort, increased review burden, and copy-paste waste—while staying transparent. Governance is consensus-based; there is no universal agreement on AI use. Key rules: disclose LLM involvement in public text; LLM-generated code must meet higher tests and quality standards; LLM output may not appear in public docs or PRs unless clearly marked; LLM reviews cannot replace human review. Data will guide future changes; broader adoption is possible.

Marcin Wichary discusses the debate over Apple ads on its surfaces (App Store, News, possibly Maps) sparked by John Gruber. He recalls Apple’s playful stance on “stickers” vs Intel Inside and notes Gruber’s zero-one-infinity rule: zero ads is best; more ads slide toward infinity. Wichary argues UI tends toward endless extensibility: add one setting or option, and others follow, increasing complexity. He cites Chrome's right-click options and iOS's Save/Delete evolution as examples, linking this to “gravity” in code and Hick’s Law. He urges design restraint, hiring people who will say no to unnecessary additions—and even admits his own sticker.

An analysis of proof systems' fragility. A supposed Lean/Nanoda verification of a Collatz proof is invalid because a kernel bug slipped through; similar bugs in Isabelle and other proof assistants show that proof objects don’t guarantee soundness. The 'dead weight' argument argues against storing proof objects: independent checkers rarely detect kernel errors, so protection should reside inside a minimal kernel. The piece contrasts 'honest toil'—developing recursive definitions directly in theory—with 'theft'—postulating axiom schemes and relying on heavy proof objects. It notes Isabelle/HOL now handles recursive definitions outside the kernel and recommends safer cores like HOL Light/Candle.

Saudi Arabia’s Public Investment Fund-led group, with Affinity Partners and others, completes a $55 billion takeover of Electronic Arts, taking the company private. It’s one of the largest leveraged buyouts, $36bn equity with about $20bn debt from JPMorgan. EA CEO Andrew Wilson stays. Analysts warn of layoffs and tougher monetization; fans worry outside influence could affect inclusivity and LGBTQ+ themes. The deal signals growing Saudi influence in sports and entertainment and prompts concerns about “sportswashing.”

qapla' is a char-level transformer trained entirely on an ESP32-S3, with hand-written backprop in C. It trains on-device (no pre-trained model) rather than inference. The tiny model (~319k params, 31-character vocab) is a single transformer block with causal attention, trained on Klingon from a small open corpus. Memory for weights, gradients, momentum, activations and corpus lives in PSRAM. Training runs hours to days, saving the lowest-loss checkpoint for on-board text generation. It proves on-chip training is feasible, not a practical Klingon assistant; Apache 2.0 open-source.

Rio 0.5 splits its terminal engine into two embeddable layers: rio-vt (Rust crate implementing the VT state machine, ESC/ANSI parsing, grid with scrollback, selection, search, PTY, and image protocols) and librio (C ABI, prebuilt static library) for broader languages. No rendering by default—you're to supply a renderer or none. The post shows how to feed bytes, read the grid, and use selection; it also covers image decoding (Sixel/Kitty/iTerm2). Librio exports a surface API for CPU-based per-cell rendering. Rio-vt is production-tested and benchmarked, generally faster than vt100/alacritty in many tasks. WebAssembly support.

Ruby Tandoh traces Britain's “golden age” of ice cream (roughly 1976–1991), when Wall’s/Unilever’s Cornetto breakthrough and a wave of industrial and marketing innovations reshaped UK freezers. Iconic launches—Cornetto (1976), Viennetta (1982), Calippo and Twister, Feast, then Magnum (1989/1990)—predicated a shift from cheap kid treats to luxe, adult-facing confections. Advances in extrusion, chocolate techniques, and European manufacturing networks, plus key figures like Kevin Hillman, underpinned the era. By 1990 Magnum goes global, and while later innovations stalled, the period left a lasting legacy on British ice cream.

Columnist John McElroy warns the auto industry is overbuilding for a shrinking future. Despite seven new U.S. plants and heavy capex from major automakers, U.S. assembly capacity operates below 70%, with about 4 million idle units. Demographic shifts—fewer young buyers and slower population growth—coupled with mobility tech like robotaxis, autonomous shuttles, urban air transit, and micromobility, threaten traditional private-car demand. Automakers must plan for 2046 or risk vast, efficient factories with too few customers.

Simon Willison argues Stateless MCP, released as MCP 2.0 on 2026-07-28, revives interest in the Model Context Protocol. Stateless MCP removes server-side state and session IDs, simplifying clients and enabling scalable apps. The post contrasts it with the old stateful MCP and highlights new tooling: mcp-explorer (a stateless MCP CLI) and datasette-mcp (Datasette plugin exposing tools like list_databases, get_database_schema, execute_sql). He also mentions an alpha llm-mcp-client and argues MCP offers auditable, safer tool exposure for LLM agents, planning to lean into MCP for sensitive apps.

Cloudflare announces Cloudflare Wallets, a programmable wallet system for agentic commerce. It provides Account Wallets (human owners) and Virtual Wallets (agents with API keys), with configurable spending policies and caps to enable safe autonomous spending. Using stablecoins and the x402 micropayment protocol, wallets let agents pay for APIs and content without human intervention. Virtual Wallets allow agents to explore many options within set limits, while Account Wallets enforce budgets and approvals. Identity via cloudflare.pay enables optional, human-readable agent identities. This supports a headless marketplace alongside Cloudflare’s Monetization Gateway.

Tracing the history of mathematical typography from Gutenberg’s lead and hot-metal typesetting to Monotype/ Linotype, typewriters, and phototypesetting, this essay argues math typesetting is an art as much as a science. It covers the 4-line Monotype system for equations, the shift to digital with TeX, Metafont, and LaTeX, and pdfTeX, showing how innovations improved precision and aesthetics. The piece concludes by urging slower, more thoughtful publishing that preserves the artistry of mathematical notation.

Korean retail investors, hit by tighter rules on domestic single-stock leveraged products, poured into overseas 3x-leverage ETFs. From mid-July to Aug 3, the top U.S. buy was Direxion Daily Semiconductor Bull 3X (SOXL), totaling about $4.64B, with three leveraged ETFs—SOXL, KORU, TSLL—accounting for roughly $5.17B in purchases, up over $1B from the prior period. Domestic leveraged-trading collapsed after the margin hike to 30 million won and a 20% per-person cap. Regulators are preparing further Capital Markets Act changes for market stability, amid concerns of capital outflows and rising regulatory risk.

Flowise is winding down as AI models mature and coding agents reduce the need for rigid low‑code workflows. Key dates: July 29, 2026 (announcement and code freeze); August 10, 2026 (repository archived); August 31, 2026 (end of life). The Apache 2.0 licensed code will remain on GitHub for forks, with core team presence ending and community moderation handed off. Users are encouraged to fork the repo to continue development. Thank you to the community.

fec is a Rust crate for forward error correction targeting SDR, space, and satellite links. It implements convolutional (Viterbi) codes (rate 1/2 to 1/8, k 4–16) with hard/soft decoding and optional SIMD acceleration on nightly builds, plus Reed–Solomon (GF(2^8)) CCSDS (255,223) coding with error and erasure decoding and dual-basis representations. It draws inspiration from libcorrect, is compatible with Phil Karn’s libfec (not borrowed), and offers a fec-shim for a C ABI. BSD-3-Clause license. Roadmap: more widths, erasures, punctured codes.
