Chen Danian returns with StartLux's local 27B model, StartLux-V1.0-27B-Preview, which placed second to DeepSeek-V4-Pro (1.6T) in CAICT MCP tests by a small margin. StartLux argues local models can match trillion-parameter cloud bots and run on consumer PCs without cloud access, using post-training and Auto Research to sharpen Agentic tasks. In benchmarks, it excelled in location navigation, financial analysis, and browser automation, beating larger rivals in some cases. The team—Chen Danyan (CEO), Guo Quanwei (CTO), Luo Yongxiang (co-founder)—plans first-year, one-click local deployments for enterprises and individuals, signaling a shift toward local models.

The piece argues that profitable, overlooked “invisible” businesses—often mundane operations rolled up under one umbrella—generate outsized returns because rivals fail to notice them. Four invisibility drivers are unknown data, private data, misunderstood markets, and stigma. It cites Steve Ross’s Kinney/Warner saga and firms like Constellation Software, Waste Management, and HEICO as examples. The lesson: stay invisible or use invisibility as a temporary moat, then decide how to reveal; to find opportunities, look beyond standard data and break consensus. AI could both erode and encode invisibility.

Private TikTok mobile API scraping guide. It explains a four-gate workflow to reach TikTok’s private HTTP+JSON API: correct device credential, signature, regional host, and TLS fingerprint. It details a four-stage device-generation and activation pipeline, explains the infamous empty-200 response, and documents 24 endpoints (profiles, videos, sounds, hashtags, search, trends) with measured success rates. The signing stack uses Protobuf Argus, two-layer encryption (Simon/Speck/SM3, TTEncrypt) and per-endpoint version gates, plus region-partitioning and JA3 fingerprints. It also covers rotating-proxy economics and deployment options (self-hosted vs done-for-you).

Japan reduced the speed limit to 30km/h on about 870,000km of narrow residential streets with no centre lines or signs, covering roughly 70% of its general roads. The change, effective this week, aims to cut deaths and serious injuries among pedestrians—especially children and older people—in crowded urban areas. While overall traffic deaths fell, fatalities on these roads have lingered near 300 per year since 2021. Pedestrians have <1% mortality at ≤30km/h, rising sharply at higher speeds. Zone-30 areas previously cut fatalities by about 30%.

Medieval dietary lore treated food as medical: foods had hot/cold and wet/dry qualities, digestion as a three-stage process that turned meals into blood and humors, so people were what they ate. Diet varied by class, season, age and complexion. Staples included cereals and bread; fruits and vegetables (often viewed with suspicion); butter, cheese, eggs; and meats from chicken to beef, with pork and venison debated. Fish was common but seen as risky, to be warmed or dried. Cooks used sauces, spices and cooking methods to alter health effects, and meals followed an order; fasting reflected religious and social status.

A.J. Jacobs eulogizes his mother, Ellen Jacobs (1941-2026), recounting their daily gratitude emails and her many roles. She was a passionate teacher who made science fun with snacks; a talented artist and cloisonné jewelry maker; a devoted grandmother and cat mom; a supportive friend and loving spouse; a book lover and long-time NYPL volunteer; and a determined optimist who faced dementia with humor. Through these multitudes she left the world better—more beautiful, kinder, and smarter—leaving Jacobs grateful for her life and guidance.

Web performance hinges on the main thread, which runs JavaScript and drives rendering; when it’s blocked, frames miss the budget and the UI stutters. Four core moves help: splitting long tasks into small chunks; batching to reduce fixed costs; prioritizing urgent work; and deferring work until it’s needed. If possible, move work off the main thread: use the compositor for transforms and opacity (FLIP for layout moves); or use workers for heavy computation with transferable data. Debounce/throttle events; IntersectionObserver can defer offscreen work; finally, drop/merge/skip tasks when feasible.

Three Irish schoolgirls—Émer Hickey, Ciara Judge, and Sophie Healy-Thow—from Kinsale tested whether rhizobium bacteria from a pea could boost cereals. Despite skepticism, they ran a three-year study, testing about 13,000 seeds in barley, oats and wheat. Treated cereals germinated up to 50% faster and produced up to 74% more dry mass. The work won Ireland’s BT Young Scientist (2013) and Google Science Fair grand prize (2014). It suggests a low-cost seed treatment for cereals, though it lacks peer-reviewed field trials and no product exists yet.

Long-form recount of 1906 NYC Lower East Side riots triggered by a city experiment to treat adenoids in schoolchildren. At PS 110, Adeline Simpson led a push, under Dr. Emil Meyer and Mount Sinai, to prevent illness by removing adenoids; 83 operations in 88 minutes, then an ice-cream party. Six days later, tens of thousands of parents flooded the streets, mobbing schools, doctors, and police in what became one of NYC’s largest riots. Fewer than 300 officers contained about 50,000 rioters; three arrests, no deaths. The episode spurred funding for preventive health in schools and Simpson’s enduring reforms.

Aaronson argues that self-reference isn’t required for LLMs to achieve strong conversational intelligence; it emerges as a byproduct of large-scale pretraining, not built in. While Hofstadter’s strange loops are philosophically interesting, AI success hinges on prediction via compression and universal computation, not explicit self-reference. LLMs can discuss themselves and Gödel’s theorem, but that doesn’t mean they rely on self-reference. Consciousness remains mysterious. Some readers argue for introspection or strange loops, but Aaronson maintains self-reference isn’t necessary for intelligence.

The Computer Museum of America reclamation project describes preserving and indexing the CMA/San Diego Computer Museum collection stored for 21 years in SDSU's Love Library basement. A 2025 grant funding indexing, fundraising, and outreach aims to raise awareness. The archive is one of the world’s largest repositories of Computer Revolution materials, including hardware, magazines, newsletters, software, books, and manuals, illustrating how transistors and ICs changed work, learning, and leisure. Researchers in sociology, engineering, anthropology, and history may use it. More info on the History section and the Current Projects page.

De Nederlandsche Bank has moved 86 tonnes of its 612.4-tonne gold stock, valued at €72.2bn at end-2025, from New York and Ottawa to London, citing rising geopolitical unrest. Conducted March–August 2026, the transfer boosts London to 32.1% of reserves (vs 18.5% in NY and Ottawa), with the Netherlands at 30.8%. It used a mix of buying, selling and physical transfer to avoid melting bars. DNB says deployment in a crisis would be quicker; it does not expect to deploy but seeks resilience.

runnrr is a local-first Mac app that turns Granola calls into a Kanban board. Things mentioned in a call become cards with transcripts attached; you can set due dates, add tags, and schedule user interviews. Notes and files stay on your Mac as Markdown; tasks use SQLite. The agent, using Claude Code/Codex, reads the card’s context to draft emails and complete follow-ups. It connects to Granola and MCP tools but runs offline by default; networked features may send data. It's free, macOS 13+, with a web fallback and no sign-up.

A guide to building a 3-2-1 backup across devices with Linux. The setup has three-layer: a working layer with a Sync folder on the primary machine synced by Syncthing to an always-on NAS and to the laptop; access via Tailscale/Runestone; Android workaround; Syncthing isn’t backup. A second layer uses a local hard drive with restic backups; exFAT chosen for Windows compatibility. A cloud layer uses Google Drive free space; photos via PhotoSync; restic was slow, so manual zips via rclone. Extras: dotfiles with chezmoi to GitHub; Timeshift for OS recovery. Mixed results; many hacks; hoping for a free setup.

Across three studies spanning seven datasets and over 880,000 texts, the widespread use of large language models as writing assistants is linked to a decline in linguistic diversity. LLMs preserve core content but homogenize writing styles and reduce writing-complexity variance by 21–50%, amplifying dominant patterns while suppressing others. These effects persist across models, prompts, and contexts and have implications for diagnostics, personalization, hiring assessments, and cultural preservation.

A USPS whistleblower warns the service’s new mail-ballot system could cause widespread disenfranchisement and “catastrophic” problems, alleging the agency rushed an untested federal portal to share voter lists and ballot barcodes in defiance of court orders. The process would verify batches by scanning barcodes; even a single mismatch could scrap an entire batch, delaying thousands of ballots. USPS says the portal is voluntary, designed to aid officials, and compliant with court orders. Senator Blumenthal and others question the plan amid ongoing court challenges.

Using the 2022 Survey of Consumer Finances, Caplan shows Americans’ net worth is far higher and age-dependent, not uniformly poor. Wealth rises with age: the richest 65–69 are ~30x the richest 18–24; median net worth surpasses six figures by the mid-30s; the 75th percentile are millionaires by the mid-50s; the 90th by about age 40. A large share could retire comfortably without Social Security (median net worth ~$400k; most wealth is home equity). Low net worth is mainly young. Savings and steady work can yield decamillionaire wealth; oppose gerontocracy and deficits.

Steve Newman argues that AI progress in data-centric tasks outpaces robotics, and demo videos misrepresent real capabilities. Achieving broadly capable humanoid workers hinges on solving many intertwined problems: dexterous manipulation; robust vision; scalable task planning and re-planning; contextual reasoning; coordination with people and other robots; speed vs. safety; power, heat, and endurance; mobility form-factor choices; safety and liability; reliability across edge cases; compute constraints on-board vs. cloud; scaling manufacturing; and political, regulatory, cybersecurity, and privacy issues. Demos reveal only a fraction; the real-world capability gap will be larger.
