DeepSeek V4 Flash 0731 posts ARC-AGI results: 89.0% on ARC-AGI-1 Semi-Private (max effort) and 61.4% on ARC-AGI-2 Semi-Private. The page lists public-eval results (ARC-AGI-1: 400 tasks; ARC-AGI-2: 120 tasks) with per-task pass/fail data, and situates the model within the ARC Prize 2024–2026 competition ecosystem and leaderboards.
Oracle bans AI-generated code from OpenJDK contributions over safety, security, and IP concerns. Developers may use LLMs privately for debugging and reviewing, but cannot submit AI-generated material to repositories or pull requests. This contrasts with Larry Ellison’s claim that AI models now write Oracle’s code; co-CEO Mike Sicilia says AI tools enable smaller teams to deliver faster. Oracle is investing $70 billion in datacenters, and S&P downgraded its rating to BBB- citing uncertain ROI.
U.S. aging trend: Census projections place the first crossover where adults 65+ outnumber children under 18 around 2029. In 2024, 65+ were 61.2M (18%), under-18 73.1M (21.5%). Since 1950, 65+ rose fivefold; children remained near 73M. By 2060, 65+ share ~24.4% (2100 ~29.1%), while 18–64 share falls relative to 65+. Three drivers: baby-boom generation aging into 65+, longer life expectancy, and sub-replacement fertility. Eleven states and many counties already crossed. Total population continues to rise toward ~370M by 2080, not shrink.
Bloomberg shows a CAPTCHA-style notice for unusual activity, asking users to verify they’re not a robot; it mentions JS/cookies, links to Terms of Service and Cookie Policy, a support contact with a reference ID, and a subscription prompt.
Tracy Durnell updates her blogroll to include more personal blogs from strangers, arguing for a people-first web. She describes a shift from event-focused news to everyday lives, uses IndieWeb concepts, and celebrates personal sites as authentic spaces that foster slower, richer connections through linking and webmentions. She calls for reviving blogrolls to strengthen online community, discusses how blogs enable conversation, and views blogging as a social, neighborhood-like network rather than solitary publishing; this piece is part of an IndieWeb carnival on community.
Explores Möbius-strip crosswords and the contested claim that Robert Guilbert created an infinite Möbius “Pago Pago” crossword. It traces how Rothenberg (1988), Raphel (2018), and Last (2025) echoed the idea despite uncertain evidence; Guilbert’s Crossword Academy photos hint at a Möbius puzzle rather than the game itself. The piece then explains how a true Möbius-strip crossword would work topologically, including toroidal and Klein-bottle variants and a diagonal word ladder, and invites readers to share information or better designs.
David Hope and Julian Limberg of LSE analyze major tax cuts for the rich across 18 wealthy nations over 50 years. They find that cutting taxes for top earners makes the rich richer but has no meaningful effect on unemployment or overall economic growth; instead it increases rent-seeking, with CEOs bargaining for higher pay at the expense of lower-income workers. Policy takeaway: avoid tax cuts for the wealthy to boost growth or reduce inequality. The findings were published as a 2020 working paper and a 2022 journal article and drew wide debate.

Beats Bitwrap uses Petri nets as a music sequencer. Each instrument is a ring; a token moves around places and triggers notes as it lands on transitions. Rhythms are derived from the Bjorklund algorithm, so 3 hits in 8 steps yield tresillo; 4 in 16 steps yields four-on-the-floor. Rings run in parallel for kick, snare, hats, and more, with different lengths to create polyrhythms. Melodies and harmony are token-based too. The same seed always yields the same track; song structure is controlled by extra nets. It runs client-side using Tone.js. Demo: beats.bitwrap.io (19 genres).
pgrust 0.2 is a Rust analytics engine claiming up to 300x faster analytics than Postgres (and competitive with Clickhouse on some benchmarks). It achieves this with batching, operator fusion, and SIMD, replacing per-row Volcano execution with batched, fused operations and SIMD-accelerated sums. In benchmarks, Postgres sums a simple column in ~20s; pgrust progresses to 1.3s (Volcano), 480ms (batching), 358ms (fusion), and 135ms (SIMD). JIT is noted as future work; readers are invited to GitHub.

Textlog is a small, public microblogging service for short notes (280 characters) and conversations, built around notes, people, hashtags, and conversations. It emphasizes a simple, pressure-free experience with no engagement tricks; joining is free, notes are public, and you can download or delete your data. Donations are welcome. Be respectful; harassment, spam, impersonation, or illegal content may be moderated or removed. Join the community or browse notes at textlog.cc (about/api/irc/github/donate/contact/legal).
A new developer is reminded that software is about people, not code. The author initially focused on coding, style, and tech, but learns that people determine a project’s success. Code exists to solve real-world problems and must meet user needs and business goals. Even the most elegant, well-documented code is useless if it serves the wrong purpose or lacks market support. Overall, developers should prioritize real-world problems and stakeholder buy-in over perfect code.

This article explains ABI as the binary interface between modules, shaped by CPU/OS, object formats, data layout, and calling conventions. On x64, Windows x64 and System V ABIs govern cross-library calls; object formats (PE/ELF) and data representation affect compatibility. It covers function calling conventions, parameter passing, and when structs are passed by value or reference, with System V vs Windows examples. It surveys Itanium (cross-arch) and MSVC ABIs, notes stability but possible breaks from compiler updates or library changes, and discusses runtime libraries, static vs dynamic linking, and strategies to preserve ABI (extern C, reserved fields, versioning).
A Science Advances study argues life on Earth arose twice: bacteria and archaea independently developed metabolism. The last universal ancestor (LUCA) had enzymes for about half of metabolism; the other half was catalyzed by metals in the environment around hydrothermal vents. Four phases trace the shift from environmental metal catalysts to self-made enzymes, ending with free-living cells after the two lineages diverged. The work also suggests an ATP substitute using phosphite and palladium.
Cloudflare unveils Kitesurf, an agent-first browser that runs on Cloudflare Workers via V8 isolates. Aimed at AI agents, it delivers a lighter, more cost-efficient alternative to Chromium for tasks like screenshots and HTML extraction. Architecture: Engine, PageScript, PageRenderer; SandboxOutbound network fetches; Dynamic Workers for per-page isolates; Boa JS for occasional evals; rendering with Blitz/Stylo; CDP-compatible APIs and Cloudflare RPC between workers. It passes 215k+ Web Platform Tests and runs in Browser Run beta with a public playground. Not suited for video, WebGL, or long-lived sessions yet; open source planned.
