Reverse-engineered and extracted maps of the DOS game Test Drive III: The Passion by Accolade. The project aims to reconstruct the 32×16 maps as accurately as possible; each tile selects a 3D mesh stored as arrays of 16-bit X, Y, Z coordinates with 8-byte polygon records. It provides a browser viewer, extracted assets (Wavefront OBJ files in objs/ and PNGs in images/), and a project gallery. Includes comprehensive file-format specs in spec/. CLI/Dev tools export OBJ, PNGs, and sprites; LST viewing. Prereqs: Node.js 20+. Install and run via npm install, npm run dev/build.

An overview of speaking machines from von Kempelen (1773) through Faber, Edison, VODER, MUSA and S.A.M., to today’s neural TTS, highlighting two patterns: singing as demo and gendered labor in voice tech. It explains Macintalk and the macOS say DSL for phoneme-level prosody, then introduces SaySynth, which uses a YAML sequencer atop say to spawn per-note phoneme voices, explores alternative tunings via Scala, and preserves the texture of its limitations as a creative tool, not just realistic speech.

WSJ 404: The requested page can’t be found. It advises checking the URL or emailing support. The page also lists popular articles (Jill Biden’s memoir and marriage, autism-therapy billing, UC professors urging SAT reinstatement) and recent podcasts (Trump taps housing official as acting intelligence chief; stocks rise on AI/Mideast worries; Trump signs AI oversight order).

Jay Caspian Kang tests whether AI writing can be as engaging as human writing. Using Claude to imitate Hemingway, Eliot, Bram Stoker, and others, he runs a 200-word–passage guessing game. Across rounds, readers could tell real from AI only about half the time, though a Bram Stoker–style piece fooled 83% of players. AI shows tells—tortured similes, odd punctuation—and, when pushed for action, often produces scenes of emptiness. Kang concludes that while AI can mimic style, humans still crave human-made writing; the written word remains.

Words of Type is an encyclopedic guide to typography and type design, detailing hundreds of terms and concepts. It covers basic concepts (alphabet, letter, glyph, character, diacritic), punctuation, layout, and typography anatomy; typographic measurements (x-height, cap height, baseline, ascenders/descenders), styles (serif, sans, italic, script), and features (ligatures, kerning, OpenType features, substitutions). It also explains font technology and digital formats (OpenType/OTF, TrueType/TTF, PostScript, WOFF/WOFF2), font structure (cmap, glyf, CFF, gvar), and principles of font construction, hinting, and interpolation, with historical context.

The article argues that despite vast sequence diversity, natural protein folds are highly redundant. By distilling MGnify-scale sequences into predicted structures, fragmenting with a spectral graph–splitter (Fiedler vector) and union-find, then clustering about 2 million fragments, they find only ~25,000 reusable structural neighborhoods; 71.5% of fragments fall into the top 1,000 clusters, and 64.3% of AFDB fragments do likewise. Foldseek singletons often underestimate novelty; a second TM-align audit narrows fold counts. For model training, they propose gamma-weighting (~0.5) to balance diversity and abundance. Implications: enzyme design may reuse scaffolds rather than exhaust backbone space, unless methods reach beyond natural folds.

America's missile production is bottlenecked by AP supply, with AMPAC the sole US producer after the PEPCON disaster; new AP capacity would take a decade amid strict regulations. Solid motors dominate stockpiles, but AP and other inputs (rare earths, titanium, niobium) create single-point failures. Liquid propulsion offers scalable alternatives using hydrocarbons and hydrogen peroxide, with automation reducing handling risks. Neo-primes—Anduril, Castelion, Galadyne, X-Bow, Ursa Major—are pursuing liquids or hybrids. Path forward: permitting reform, second AP sources, and demand signaling for liquids; reforming the solid supply alone is too slow.

An aggressive critique of "vibe-coded" websites that rejects clean-code dogma in favor of speed, scale, and AI-driven workflows. The author argues that maintainability, hand-crafted semantics, and even accessibility have lost to complex, agent-powered systems that juggle hundreds of npm deps, large bundles, and token-sucking pipelines. Projects are driven by hype ('native', 'agentic'), not readability, with open source contributions throttled by bots and tests rewritten by agents. In short: craft remains, but as nostalgia; attention now trumps quality.

Pluto 1.0 debuts after six years as a reproducible, reliable, interactive Julia notebook environment. Highlights: isolated package environments with automatic add/remove, precise Project.toml control, and reproducible sources; export to Julia, PDF, or self-contained HTML (offline since 2025); pluto.land sharing. Reactivity improvements include disable cells and confirm-before-long-runs. PlutoUI.jl adds widgets; PlutoTeachingTools.jl for live-homeworks; APIs to build custom widgets. Accessibility in 16 languages. Education updates: improved error messages, course-website template, 40 featured notebooks, PlutoTurtles. AI: one syntax-error fixer; Editor: CodeMirror 6 parsing, autocomplete, jump-to-definition. Ecosystem: governance and Pluto organization.

Capstone is a lightweight, open-source, multi-platform disassembly framework for binary analysis and reverse engineering. It supports many architectures (ARM, ARM64, x86, MIPS, RISC-V, WebAssembly, SPARC, PowerPC, M68K, etc.), offers an architecture-neutral API with semantic details for instructions, and bindings for dozens of languages. It is thread-safe, embeddable in firmware or kernels, and BSD-licensed. Widely used in security research, it ships with strong community testimonials and active development, including 6.x alpha releases and frequent security fixes through 2025–2026.

A security researcher shows a 1-click GitHub token theft via github.dev, VSCode in the browser. The OAuth token used by github.dev can access all repos, including private ones. By abusing VSCode webviews, cross-origin messaging, and keyboard shortcuts, an attacker can inject a malicious local workspace extension that runs and exfiltrates the token and repo list. A PoC demonstrates stealing the token. Mitigation: clear github.dev cookies/data to stop the attack; otherwise you're compromised. VSCode mitigations like CSP and DOMPurify help, but the disclosure remains contentious.

Are blue zones real? Not settled. The term, from Sardinia’s centenarians, Okinawa, Nicoya, and Loma Linda, became a billion-dollar brand led by Dan Buettner. Critics say data validation was fragile and several zones no longer show extreme longevity, with debates over how to define a blue zone. Some researchers warn zones may be waning or evolving, while new candidates surface. Regardless, the lifestyle principles—plant-based diets, regular activity, social ties—are broadly supported and influential. The larger issue: hype and profit around the brand risk overshadowing real science.

LLMs are not the black boxes critics claim. Mechanistic interpretability, via circuit tracing and a replacement model, uncovers sparse, human-friendly features that map to high-level concepts and reveal multi-step reasoning during a forward pass. Models can "think ahead" in planning tasks, with intermediate concepts guiding later steps; this occurs even in non-language domains. The model’s stated explanations often diverge from its actual process, giving it a "subconscious." Understanding this inner wiring can improve learning algorithms, steering, and safety—Anthropic’s biology paper is a landmark in this effort.

AI search summaries feel like progress but aren’t. They flatten diverse sources into a single confident paragraph, erase uncertainty and caveats, and obscure the signals that matter—source credibility, recency, and disagreement. That harms verification, especially for medical, legal, and technical queries, where a wrong, confidently stated answer is costly. Web traffic to primary sources shrinks, weakening the incentive to create quality content and thinning long-tail communities. By returning results-only, you get multiple perspectives and preserve the discipline of checking sources. Useful only for low-ambiguity tasks; otherwise avoid summaries.
