Entombed is an Atari 2600 maze-generation algorithm that builds a maze one row at a time from a fixed five-neighbor lookup table. With only 128 bytes of RAM, the original game scrolls upward and never stores a full maze, using a mystery table to produce walls, passages, or random bits; two correction passes prevent repetition. The author implements a raycaster variant, encoding each row as a 32-bit bitmask, keeps all generated rows, and allows walls to be broken. They adapted the C version from 3DSage, added a Backrooms skin, and released a Three.js browser demo by Claude, with links to the repo and references.

An enthusiast shows how to re-enable iChat AV on Leopard by recreating Apple’s SNATMAP lookup. After early TLS redirects caused failures, they reverse-engineered the UDP SNATMAP protocol (port 5678) and built a self-hosted SNATMAP server with a Python implementation. They provide a spec and testing setup, plus self-hosting steps: host snatmap.txt at /configurations/macosx/ichat/1/snatmap.txt and map configuration.apple.com to your server via /etc/hosts; or use the author's server for a few users. In a lab with two NATs, two Macs can chat over the Internet; iChat doesn’t require an iSight.

An amused dad recounts a day with his four-year-old, Guy, who insists on 'wood tape' and a trip to the hardware store. Guy leads the shopping, choosing tape, paint, and lumber, while the dad stays mostly in the background. In the end, the 'wood tape' turns out to be masking tape for painting a checkerboard table for Guy’s tree house. The boy had planned the project all along, not improvised purchases. The dad is overwhelmed with pride and gratitude for his son's thoughtfulness and their shared effort.

Common Lisp is the best language today, especially with large-language-models. Its homoiconic code-as-data design and macros let you build domain-specific languages and tailor DSLs for your product, keeping changes aligned with a company’s domain opinions and cutting costs. Lisp’s image-based execution minimizes crashes; debuggers let LLMs fix problems quickly. Lisp programs tend to be shorter, reducing token costs and keeping more of the program in the LLM’s context. Despite a smaller library ecosystem (Quicklisp), porting or self-implementing code mitigates this. Hiring isn’t a barrier; teach Lisp in interviews. Cited: Paul Graham.

photoc is a command-line toolset for photographers to review, organize, and share photos from the terminal. It can summarize shoots, read metadata, detect blur and duplicates, rename and sort photos into folders, generate contact sheets, and produce smaller copies while optionally removing GPS data. It supports JPEG and Sony ARW metadata (other RAWs not yet supported). It is read-only by default and never overwrites originals; changes require --apply or --in-place. Not a RAW developer or full image editor. Install via Homebrew or shell installer; Windows not supported yet. Includes commands like exif, stats, timeline, duplicates, focus, and scrub.

Bradley’s review opens with nostalgia for Ordnance Survey pocket maps—orange 1:63,360 sheets, then magenta 1:50,000, then yellow 1:25,000—and notes how scale and format shaped navigating Britain. It frames Will Millard’s Mapping Britain: The Story of an Island through the Ordnance Survey Archives (Weidenfeld & Nicolson, 256pp) but, as the paywalled piece suggests, offers only a hint rather than full analysis of the familiar maps.

Rising diesel prices pushed 16 trucking companies into bankruptcy in late August/September, from small outfits to larger fleets. The squeeze hit margins and made it hard to pass costs to customers; one Florida Amazon contractor filed Chapter 11. Four Texas operators were among the bankruptcies, prompting a state disaster declaration to ease untaxed diesel use for agriculture. With winter demand and Middle East supply concerns, significant price relief before year-end seems unlikely.

An issue titled 'Photopea developer concerns' accuses Photopea of copying work from the author’s site (photopea.com) and implores the maintainers to build their own editor rather than stealing their code. The author questions GitHub’s tolerance of piracy and provides no responses to 'where it lives in Photoshop' or 'how it should behave.' The note states the issue affects the editor (not saved files) and that PSD files should round-trip; reactions are currently unavailable.

12 cheap Zigbee temp/humidity sensors from Aqara, Sonoff, Tuya, ThirdReality, Zemismart and Moes under $15 were tested head-to-head against a calibrated reference (BLE Xiaomi MHO-C401 via Zigbee2MQTT). The study covers build, power, form factor, accuracy, resolution, reporting intervals, OTA, and extra data points. Results: all tracked trends; best temperature accuracy by Paulie and Carmela (~0.2°C). Humidity leaders: Tony, Chris, Paulie, Meadow, Carmela. Low-temp fridge test favored Tony, Carmela, Paulie, Junior, Chris. Verdict: accuracy alone isn't enough—battery type, size, and adjustable reporting interval matter. Top picks: Best overall — Paulie; Best runner-up — Moes ZSS-S01-TH; Best AAA sensor — Carmela.

Researchers extend a piano-MIDI transformer (Aria) with a gated cross-attention mechanism conditioning on a learned pianist embedding, enabling imitation of 12 jazz pianists from PiJAMA. They fine-tune Aria on solo performances and insert cross-attention in the final eight layers, with a gate controlling influence per step. Evaluation uses a pianist classifier on generated continuations; conditioned runs achieve 70% agreement with the intended pianist (vs 37% without), while a classifier trained on generated music detects real recordings at 95% accuracy. The results show the model can embed and reproduce a pianist’s style beyond perplexity measures.

Christian Szegedy contends that mathematics is graduating from the era of solitary, heroic problem-solvers to a mature, industry-scale field. He contrasts youth competition culture with the real work of ‘pure mathematics’ as jungle exploration: mapping terrain, funding expeditions, and inventing tools; conjectures are rocks to climb, some turning into majestic mountains. AI progress is a rising airplane: current tools seem primitive, but soon flights will reach farther, while public vanity (flag-planting) fades. Ultimately, mathematics will become the infrastructure of science and technology—an enterprise funded, networked, and valued for guiding others—ending the lone-climber myth and opening a continent to map.

After months with Deno, the author returns to Node v26.10.0, noting modern ECMAScript sugar, no require, and faster builds after migrating a static site generator from Deno to Node (replacing Deno.serve with Hono/node adapter and Deno’s fs/path with node:path). They optimize package management (NVM via curl, PNPM with trust policies, and PNPM aliases) and avoid NPM malware concerns. TypeScript under node_modules remains unsupported; Tsdown helps. Deno declines due to instability and layoffs; Node has caught up and sometimes surpasses it. Brew uninstall deno.

Colin Armstrong argues that with LLMs, building small, cheap tools for personal annoyances is now feasible and worthwhile. He describes creating heade.rs, a domain-lookup app (DNS, WHOIS, TLS, etc.) in a few prompts using Claude Code, deployed on Cloudflare, focused on speed, aesthetics, and usability rather than monetization. It costs less than a cup of coffee a month and doesn’t need to sell to exist. The economics favor more shipping of cheap tools, even if they don’t rank high or reach wide audiences. Personal projects can be worthwhile whether they solve one person’s problem or spark broader interest.
