Dr. Drang describes a Mac widget named planets that shows azimuth and altitude for the Moon, Sun, and planets (per an ancient definition up to Saturn) using Astropy. The Python script computes AltAz positions from a fixed location and UTC, determines each body's constellation, formats lines, and pipes them to TerminalWidget. A launchd plist runs the script every 30 minutes. A custom 16‑point compass function translates azimuth to direction. He notes visibility considerations and uses an eclipse example to show the widget’s practical usefulness.

Treats brain wiring as a genome-encoded developmental program to build a brain within genome and time budgets. Three strategies are analyzed: (1) identity lists—time O(n) per target and space O(nm log n); (2) guideposts—shortens paths to O(n^{1/3}) but inflates instruction space; (3) coordinate addresses—division-derived, inherited addresses with compact bit-flip rules; storage O(t m log n) and time O(n^{1/3}). Strategy 3 fits genome budgets for large brains, unlike 1 and 2. The authors argue the coordinate system may reflect real developmental maps read from gene expression, with noise, plasticity, and evolution shaping the program.

LymeAlert, due this August for about $50, is the first at-home test to detect Borrelia burgdorferi in a tick. After removing the tick, users pulverize it in a Tick Crusher, add a buffer, and insert a test strip for a 15-minute immunochromatographic result. The kit remains effective for up to 12 months. An app reads the strip and links to telehealth. Field pilots with veterinarians are underway and hotspot maps will be shared. The CDC cautions that tick tests do not diagnose human Lyme disease and false results can occur; only about 1–5% of bites lead to Lyme.

Writergate is Zig’s overhaul of I/O, replacing GenericWriter/Reader with concrete, vtable-backed types and explicit buffering. The old generics polluted APIs; the new three-level vtable (Io backend → Io.Writer/Io.Reader → concrete File.Writer/File.Reader) centralizes I/O and enables async, better performance, and precise errors. Changes: std.io becomes std.Io; buffering is provided by the caller; you must flush; errors are specific. Common pitfalls include forgetting to flush, misusing format specs, and copying interfaces. See migration notes for details.

T3X/0 is a small, portable procedural language, block-structured, recursive, and almost typeless. Its compiler is free under 0BSD/public domain. Syntax resembles Pascal; semantics resemble BCPL. The package includes two editors with built-in compiler support and a three-key compile workflow, even on CP/M. Used as a teaching language and formally defined in The T3X Programming Language - Formal Definition. Examples and a Hello World program are provided. It runs on Unix (386/x86_64/ARM), FreeBSD, macOS, DOS, and CP/M; includes TCVM, self-hosting, and cross-compilation. Distributions: t3x0-47.zip and related archives.

The Möbius strip is locally orientable but globally non-orientable: a loop flips the 'up' side. The article connects this to solving df/dz = (1/2z) f(z): local power-series solutions exist near any point, but analytic continuation around z=0 yields monodromy, sending f(1) from 1 to -1. The set of all solutions forms a vector bundle; over the unit circle the attached directions twist into a Möbius strip. This nontrivial topology explains the absence of a single global solution and shows how algebraic topology informs differential equations.

Independent booksellers report a surge in bulk sales of secondhand titles, puzzling traders as shipments head to distant warehouses. The trend is linked to AI training, prompted by a US court ruling that using purchased books to train AI can be permissible. Court documents reveal “Project Panama” to destructively scan books for datasets, though firms say they do not destroy rare volumes. UK copyright law still requires first-owner permission for copying. The situation raises ethical concerns about pulping and discarding valuable titles.

Yadda 3.0.0, a JavaScript BDD library that maps natural-language specs to executable steps, is now Node-only with moderniser updates: no browser bundling, removal of CasperJS/PhantomJS/Bower/Component, ES6 syntax, TypeScript definitions, and new Playwright/Puppeteer examples. The release, largely authored by Claude Code via Opus 4.8 under a phased plan, emphasizes separating code and tests and tighter orchestration for multiple AI agents. The author argues AI-enabled executable specifications reduce cost, improve coherence, and function as contracts; v3.1 adds GitHub-flavoured Markdown support. Available on npm and GitHub.

Sophontic argues that geometric reasoning—training a model's internal geometry—delivers reasoning performance up to 60× that of larger models. They use a perturbation-based flip-rate test on paired items, where changing a fact should flip the answer and surface heuristics fail. Their compact prototype shows reasoning need not scale with size. An eval kit with public and synthetic reasoning surfaces and open-source paired perturbation records is releasing soon. An interview with Julian D. Michels explains why frontier AI may shift from bigger data centers to geometry-based reasoning. Sophontic, Inc., a 2026 Delaware C-corp.

AI work is less predictable than traditional software, requiring context, clarity, and feedback. It’s not about making AI human; it’s about treating interaction as collaboration rather than a compiler. Good prompts matter, but shared context, examples, corrections, and reusable instructions reduce misunderstandings and align the system with your intent. The investment is in explaining why the work matters, what a good result looks like, and where judgment is needed. AI shifts software work from issuing commands to leading through conversation; leadership skills persist even as the technology is new.

This Rust module implements a Brazil 2026 election filter for the home-mixer. It exposes BRAZIL_2026_ELECTION_USER_IDS, a lazily initialized FxHashSet<u64> containing user IDs reported to Brazil's Electoral Court for the 2026 election. Comments explain that app providers must exclude from recommendations any channels/profiles listed, except for paid boosts; the list includes obfuscated IDs and some usernames for transparency, and references the dataset at dadosabertos.jus.br.

Debian Developers must sign ballots and email them to [email protected]. The ballot offers 9 ranked choices (from banning LLM contributions to allowing AI-assisted or AI-generated work under various conditions, plus a “None of the above” option and human-centric proposals). It explains signing requirements, voting secrecy via hashes, and points to full text and contact details for questions.

Raph Levien proposes hyperbezier, a 2D curve family defined by the Cesàro equation κ(s) = (a s + b)/(c s^2 + d s + 1)^{1.5}, aiming to outperform cubic Béziers by offering both smooth curvature variation and high-tension regions. The curve includes exact Euler spirals (c=d=0) and circles (a=0) as special cases, and can resemble hyperbolas, elastica, and squircle-like shapes. It more naturally fits asymptotic behaviors than Béziers and can be integrated to Whewell equations. A practical mapping to Bézier control points exists; future work includes implementing splines, curve fitting, and pen-data fitting.

Eigendrum lets you draw a drumhead shape (outline or equations) and hear its vibrational modes. The shape is solved as −∇²u = λu with u = 0 on the rim; eigenmodes are found via finite elements. A strike excites a mixture of modes according to the mallet’s impact, while nodal lines stay silent. Shapes can be drawn with polar/parametric equations; you set a reference pitch, damping, and the mallet model. Free, MIT-licensed; hosted at eigendrum.com with source on GitHub.
