An essay on well-being in an era of algorithmic social media. It argues that attention-driven platforms harm health, relationships, and presence, feeding negativity, greed, and distraction. The author proposes a grounding trio—health, family, and self-contentment—and a purposeful life as antidotes. To escape the algorithmic trap, he advocates an open, algorithm-free internet: direct connections, newsletters, and personal blogs, plus open social media built on the AT Protocol (e.g., Bluesky) where users own data and content. Regulation of big tech and more offline time are urged to restore balance and true connection.

After announcing her divorce on Instagram, Eira Tansey found AI-generated text impersonating her voice attached to her post and extra marketing language she did not write. She calls it non-consensual AI impersonation, obscured by hidden metadata and SEO bait. Tansey laments the lack of consent and transparency in AI reproducing personal narratives, condemns cliché wellness language, and argues it erodes women’s agency and authenticity. She highlights trauma, financial insecurity, and the need to control her narrative, criticizing infrastructure that profits from such impersonation.

The piece surveys how winter solstice monuments—some up to 5,000 years old—frame the Sun on the solstice and mark the year’s turning. It highlights Maeshowe in Orkney, whose passage aligns with sunset, and explains the solstice as a moment of death and rebirth guiding ancient survival and farming. Besides Stonehenge, Newgrange, and Callanish, it traces later solar-influenced art like Nancy Holt’s Sun Tunnels, James Turrell’s Roden Crater, and Hiroshi Sugimoto’s Enoura Observatory, which reframe nature’s rhythms as a living clock and reconnect us with the cosmos.

Felt introduces Lightning, a real-time tiling engine built on Tippecanoe that lets you edit tiled data instantly at any scale without sacrificing rendering speed. It uses a merge-on-demand architecture: base tiles generated once, an edit database tracks changes, and a dynamic tiling engine merges edits with base tiles in real time. Benefits: instant edits across millions of features, no tile regeneration downtime, multi-user live editing, dynamic statistics, and real-time updates to maps, tables, and dashboards. Already powering Felt datasets; available in Felt Enterprise. Enables creating new layers, editing geometries, and attributes immediately.

This is a comprehensive catalog of music programming languages and environments, covering notation, synthesis, analysis, and algorithmic composition. It lists dozens of systems—from CLM, Csound, and SAOL to SuperCollider, FAUST, Pure Data, OpenMusic, and Open Sound World—describing their runtimes, data models, and capabilities (MIDI, real‑time synthesis, score generation, and live performance). Platforms range across Mac, Windows, and Linux, with diverse implementations (Lisp, C, Java, C++), and many emphasize generators, multitasking, and extensibility for composers and researchers.

The author explains a lightweight nginx-based defense against AI web crawlers targeting Forgejo. The config lets regular access through only if a specific cookie is present; otherwise, requests are redirected to a 418 page that runs JS to set a cookie named Yogsototh_opens_the_door and reload. Special-case bypass exists for git/ git-lfs user agents and for users who already have the cookie. The author prefers this minimal, JS-reliant approach over heavier tools like Anubis, acknowledges it can be bypassed, and notes the risk of future crawling pressure requiring tougher solutions.

An exploration of rethinking parentheses in programming languages. The author contrasts standard grouping (atomic or paren-wrapped expressions) with an 'anti-grouping' idea inspired by Python: a tokeniser tracks nesting depth and assigns a 'friendliness' score to tokens, letting a precedence-based parser enforce binding instead of grammar. This lets grouping be handled by operator precedence, while parentheses remain in the token stream. To avoid infinitely many precedences, a precedence-climbing parser is used. Examples show how different friendliness settings change binding, and future work asks about double-parenthesising, involutions, and names for parentheses. Python-style indentation and paren handling are cited.

Gleam's bit arrays let you build and pattern-match binary data via segments (value plus options). The default segment type is Int (8-bit signed unless overridden). Other segment types include Float, String (UTF-8 by default; utf16/utf32 options), UtfCodepoints (utf8_codepoint, utf16_codepoint, utf32_codepoint), and BitArray. Options such as size, unit, and endianness tailor encoding; endianness defaults to big endian. Pattern matching largely follows construction syntax but has limits: arbitrary-length strings can’t be matched; codepoints are matchable; segment types aren’t stored. JavaScript support is partial; an NBT example decodes/encodes Minecraft data.

This post shows a Haskell single-pass Huffman coding by fusing the standard multi-pass algorithm into one traversal. It explains techniques to collapse passes: circular programming (laziness), There and Back Again (zip with reverse), Cayley representations (efficient monoid/Endo tricks), and mapAccumL-style traversals. Starting from a conventional Huffman pipeline (frequencies, heap, tree, mapping, encoding), it progressively merges steps so the frequency build, tree construction, code mapping, and encoding happen in one pass. The result uses an applicative Circular structure to thread state and produce the final codes alongside the tree.

Op-amps can do analog math, though errors accumulate and scaling is limited. An op-amp outputs Vmid plus a large gain times the input difference, with a narrow linear region near Vin+ ≈ Vin-. This enables: (1) non-inverting amplification: Vout ≈ Vin+ · (1 + Rf/Rg); (2) summing: Vout ≈ VA + VB + VC; (3) subtraction: Vout ≈ Vzero + (VA − VB) on single-supply; (4) multiplication/division via log/exp converters: convert inputs to exponents, sum, then back; (5) integration: capacitor charging under constant current yields a ramp, supporting integrators, including a single-supply non-inverting variant. Useful in ADCs despite practical limits.

Aliasing stopped optimisations: in a Counter example, using int allows the span to alias the Counter’s total, causing per-iteration memory writes; using long invokes strict aliasing, so the compiler assumes no alias and can keep total in a register and only write back at the end, aiding vectorisation. Fixes include accumulating in a local variable (and updating total later) or using __restrict to promise non-aliasing (non-standard). Aliasing is a tricky C/C++ pitfall; check Compiler Explorer to spot unexpected memory writes. Day 15 of AoCO2025 by Matt Godbolt.

Explains a 60fps, purely functional Boids flocking demo using quadtrees in Clojure/JS. Key ideas: a Boid with position, velocity, perception; initialize a 200-strong flock in an atom; update via alignment, cohesion, and separation scaled by max-speed and max-force; wrap edges. The quadtree gains MINIMUM-LEAF-WIDTH and a subdivision that assigns objects to children with filter, and a search that uses squared distances to find nearby boids. The post discusses purity trade-offs, performance, and links to Github, with note on future web workers.

Luke Howard’s 1865 essay chronicles his lifelong cloud studies, beginning with the 1803 Essay on the Modification of Clouds and introducing the cloud taxonomy still used today: cirrus, cumulus, stratus, nimbus. A chemist by trade and keen observer, he argued that clouds are distinguishable patterns requiring long, habitual observation. The project merged science with Romantic art: Howard produced landscape watercolors and collaborated with Edward Kennion; Goethe even praised him in a poem. The article notes the engravings’ role and Howard’s warning against relying on images alone, urging firsthand Nature study.

NASA’s James Webb Space Telescope observed PSR J2322-2650b, a Jupiter-mass exoplanet orbiting a pulsar in a tight 7.8-hour orbit. The atmosphere is helium- and carbon-dominated, with detectable molecular carbon (C3 and C2) and effectively no oxygen or nitrogen, hinting at carbon clouds that could condense into diamonds deeper inside. The planet is stretched into a lemon shape by strong tidal forces and sits in a rare black widow system. Its formation remains mysterious and challenges current planet-formation models. Webb’s infrared capabilities enabled this discovery, inaccessible to ground-based observatories.

An article titled Kernighan's lever explains how motivation fuels programming growth. It contrasts Kernighan's two quotes on debugging and clever code, then coins 'Kernighan's lever': a small initial push to implement functionality can trigger substantial long-term skill growth as motivation shifts toward mastering the problem. Avoiding cleverness to ease debugging may stall growth. Using flow theory, progress should be in the 'flow' zone—challenging but solvable. The takeaway: tackle problems to gain experience and become more capable, even if it means embracing cleverness despite debugging costs.
