Mysteries of the Griffin iMate describes reviving a vintage Apple Extended Keyboard II via a Griffin iMate ADB-to-USB adapter. The iMate failed intermittently; the culprit is an undocumented CR1225 coin-cell battery in the iMate powering a “USB power button” circuit that ties ADB PSW to USB wake. Replacing a dead battery with CR1220 and adding a decoupling capacitor between BATT+ and ground restored reliable operation. The author traces the circuit, discusses noise issues, speculates on obsolescence, and concludes with lessons about not starting new projects.

A London blogger surveys roof terraces, weighing access and views. Highlights: The Terrace at 1 Leadenhall (new, 4th floor; fast, odd access), The Garden at 120 Fen Court (largest, 15th floor, 360° views), One New Change Roof Terrace (6th floor with cathedral vistas), and Lookout/Horizon 22 at 8–22 Bishopsgate (50th–58th floors) for higher panoramas. Tate Modern Level 10 is no longer accessible; The Post Building Roof Garden (9th) is open but often closed for maintenance; Sky Garden at the Walkie-Talkie is pre-booked or private. Views from The Garden at 120 or planning ahead for the high terraces.

NLnet Labs marks one year of Roto, a JIT-compiled, statically typed scripting language for Rust. Over the year, six versions introduced features like while/for loops, f-strings, enums, lists, operators, generic parameters, and global consts, with improved Rust integration via the library! macro and a Rust-like syntax (fn, //). Roto gained a logo, expanded docs, and adoption by projects like Iocaine. Presentations at EuroRust 2025 and FOSDEM 2026; future goals include hashmaps, state, generics, and tooling (formatter, LSP).

breathe-cli is a macOS-only terminal app (Python, no deps) for paced resonance breathing to train vagal tone. A single file, breathe.py, runs in the terminal and targets ~6 breaths per minute with presets: balanced (5-5), calm (4-6), extended (4-6; longer exhale). Safety: no breath holds or rapid breathing; 8-second minimum cycles. Usage: breathe [options] to pick preset, duration, and logging (to ~/.breathe_log.csv). Not a medical device; MIT license; created by Marek Kowalczyk. Personal resonance frequency requires HRV hardware; 6 bpm is the default.

An Alghat desert rock that looks like a seashell prompts a DIY morphometrics study. The author builds a pipeline: extract a centered, scaled 256-point shell contour, compute squared Euclidean distances between shells, and use PCA to reduce to latent space (PC1 ~ pointiness; PC2 ~ symmetry). Projecting the fossil suggests the closest modern shell is Sphincterochila candidissima (earliest fossil ~38 Ma). The work notes morphology alone isn’t definitive for lineage and may reflect convergent evolution; users can explore the shell latent space at shell.hawzen.me.

Platform-agnostic, open specification of the technical features a good website should have, grouped into topics (Foundations, SEO, Accessibility, Security, Well-Known URIs, Agent Readiness, Performance, Privacy, Resilience, Internationalisation). Ties to WHATWG, W3C, IETF, WCAG standards. Works with any tech stack. Built in the open under MIT; per-page Edit on GitHub; MCP server and Agent Skill; llms.txt for markdown. Users audit, learn, and improve via PRs.

komi-learn provides continuous memory and self-improvement for AI coding agents. It watches your session, distills durable lessons (your style, fixes, techniques) in the background, and recalls relevant learnings at the start of the next session. No manual saving or slash commands required. It works with Claude Code and Codex, and can be installed via pip (pip install komi-learn). It supports an optional community pool of signed, content-addressed learnings, with safeguards to filter secrets. Requires Python 3.10+, optional crypto and semantic recall features; offline demo available.

Bryan Macomber’s Mechanical Pencil is a site of engineering tear-downs and deep-dives into everyday objects. He disassembles products (e.g., Pilot G2 pen, Zippo lighter, Bic mechanical pencil, Pez dispenser), CADs, illustrates each view, and animates them to reveal how they work. The project blends mechanical engineering and art, explaining the creator’s process and motivation. New entries showcase classic items (G2 pen c.1997; Zippo c.1933; Bic c.1988; Pez dispenser c.1952). Visitors can sign up for updates and contact Bryan.

LangGraph is a graph-based framework for stateful AI workflows, with checkpointing and human-in-the-loop gates. It suits problems where output depends on earlier results and where human review is needed. It is not always preferable to deterministic workflows handled by Airflow/Prefect, nor necessary for simple Python. Key patterns: lean state schema, explicit edge routing, upfront human gates. A 19-node financial pipeline shows maker–checker with review routing; common production faults are state growth, missing error handling, lack of validation, and weak monitoring. For consultants, demand real production experience and a clear validation approach; start with architecture discussions before coding.

DEC's PDP-8–based DECmate II, launched 1982, was the line’s peak—a compact office computer built around the HD-6120 PDP-8–compatible CPU, with 32kW main and 32kW CP RAM, RX50 dual floppy, VR201 monitor, LK201/LK401 keyboard, and optional Z80 APU or XPU for CP/M/MS-DOS. It booted via slushware from ROM in RAM and could run WPS-8, COS-310, and OS/278 (an OS/8 derivative). Despite compatibility quirks, it sold on price and software support. Its siblings (Rainbow, Pro, DECmate III) and VAXmate followed, but the PC era ultimately eclipsed the DECmates.

AV2 is the Alliance for Open Media’s next-generation video coding spec, building on AV1 to improve compression for streaming, broadcasting, and real-time video. It defines bitstream syntax, semantics, and decoding processes for conformance, and adds enhanced AR/VR support, multi-program split-screen, better screen content handling, and a wider quality range. The AVM reference software accompanies the spec. Current release is AV2 v1.0.0 (May 28, 2026); working draft v13 superseded. Resources include PDF, Additional Tables (C headers), a Syntax Browser, and AVM as the reference software.

Racket v9.2 is released. Highlights include stricter non-linear pattern checks in match, Typed Racket fixes for asin/acos with complex results, and the #%foreign-inline form now considered unsafe. Unicode 17.0 is adopted, with groundwork for a static ffi2 foreign interface. The terminal-file-position now counts bytes written, cross-phase persistent modules support more quoted data, and several core forms are rewritten to racket/kernel syntax. A new impersonator-predicate, polymorphic struct type printing with type arguments, and stepper number display aligned to language settings are included. Scribble docs and margin notes have updates; Big-bang .dmgs support close-on-stop. Thanks to contributors; download link and release page provided.

The post argues that while building platforms is easy, getting people to discover them is the real bottleneck. AI tools collapsed build costs, flooding the market and increasing attention competition. In the past, fewer competitors, early social platforms, and higher technical barriers made discovery easier; today those filters are gone. The solution is to develop non-linear, long-term distribution skills: publish content, engage in relevant communities, make the platform shareable, test ads, and be patient. Distribution skills compound across projects; you win by helping others get found as well as by building.

Shantell Sans is an open-source, variable font by ArrowType based on Shantell Martin’s handwriting, designed to be friendly, readable, and usable across contexts. It blends playful, handwritten character with professional metrics, inspired by Comic Sans but expanded with multiple axes: Weight, Italic, Informality, Bounce, and Spacing (and later Cyrillic support). Released under OFL and distributed via Google Fonts and GitHub, it includes Latin+Cyrillic glyph sets (380+ languages) and OpenType features. It aims for everyday appeal, wide accessibility, and animation-ready displays. It has been used by Whitney Museum shop, Cash App, tldraw, and univer.se.

Article argues for centralizing Rust error handling with a single AppError enum to replace scattered error types (sqlx::Error, reqwest::Error, etc.). It demonstrates using map_err to intercept and wrap foreign errors into AppError (with logging) before ? propagates, and using impl From<IOError> for AppError so the compiler auto-converts errors. This yields a cohesive, boilerplate-free design without heavy macro crates, providing one contract (Result<T, AppError>) across modules. Concludes it's transformative for Rust services; credits peer 'Joban' for inspiration.
