Nick Carlini builds Regex Chess, a 2-ply minimax chess engine expressed as 84,688 regular expressions. The post shows a tiny regex-based CPU that stores state as a string with a stack and variables, and uses regex rewrites as instructions (push, pop, lookup, assign, cond, reactivate). It compiles Python-like code via symbolic execution into this instruction set and runs a parallel, SIMD-like search across threads created by fork instructions to evaluate a depth-2 minimax. It includes pawn/move generation examples and performance tweaks; code is on GitHub.

Modern C++ compilers can devirtualize calls reliably when the object's dynamic type is known (e.g., direct construction or dataflow analysis) or when there is a proof of leafness for the static type (e.g., final class or final method, or internal linkage/incomplete types preventing external derivation). The article surveys edge cases and notes varying support among GCC, Clang, MSVC, and ICC, with some patterns failing on certain compilers. It mentions whole-program/LTO potential benefits but does not analyze it. A quirky “proof-of-leafness” via final destructors is discussed but not widely adopted.

Three months into using the Onyx BOOX 25.3” Mira Pro Color as a primary monitor, Wickström finds it energizing and beautiful but costly (~$2000) and not for everyone. He runs a full NixOS setup and has crafted near-monochrome themes for Neovim, Zed, and Ghostty, plus vivid accents. He uses two modes: Reading (sharp, vivid; terrible for typing) and Writing (low latency; more grainy color). Latency improves in Writing mode; ghosting is minimal. Color panel needs backlight unless in bright light; outdoors helps. An open-source NodeJS tool with Hyprland replaces the monitor’s menu. He enjoys it but cautions others.

Earth’s radio bubble is a growing sphere of all EM signals from humans, about 240 light-years across. Signals travel at light speed; the radius roughly equals years since transmission. Most are accidental leakage, not deliberate messages. The 1974 Arecibo Message was deliberate, currently ~52 light-years away. At interstellar distances leakage is undetectable; only targeted, high-power transmissions have a real chance of being decoded. As of 2026, several thousand star systems lie inside the bubble, with Voyager inside the shell. The article links this to the Fermi paradox, noting timing and geometry, and includes a visualization using HIPPARCOS data.

Pope Leo XIV’s first encyclical Magnifica humanitas, on preserving the human person in the age of artificial intelligence, will be published on May 25, 2026. A presentation at the Vatican Synod Hall that day will feature the Pope and speakers including Cardinal Víctor Manuel Fernández, Cardinal Michael Czerny, Professor Anna Rowlands, Christopher Olah (Anthropic), and Leocadie Lushombo. Cardinal Secretary of State Pietro Parolin will give closing remarks, followed by the Pope’s address and blessing. The release marks the 135th anniversary of Pope Leo XIII’s Rerum novarum.

Cloudflare’s lava-lamp entropy wall is marketing, not security. The piece contrasts two views of randomness—intrinsic vs. epistemic—and argues the latter matters for encryption. Through a one-time-pad example, it shows reusing randomness leaks information and that modern crypto uses cryptographically secure pseudorandom number generators (CSPRNGs) rather than physical entropy. It prescribes a practical RNG: a 256-bit master key, per-server local keys, fast key erasure, and careful handling to avoid forking streams. Prefer ChaCha20 over AES-256-CTR, seed locally from entropy, and avoid parallel RNGs. In short: drop the lava lamps; rely on local CSPRNG-based randomness.

AI did not invent new attacks in crypto but lowered attacker labor costs, turning exploits into a cheap, subscription-based activity. Crypto’s public ledger and open-source code make it the clearest, measurable battleground for AI-enabled crime, evidenced by the Mexican government breach, vibe-hacking extortion, and an Algerian amateur. On-chain losses 2021–2025 exceed $11.9B (plus scams and collapses in the upper ranges). Defense requires expert triage; offense is commoditized via subscriptions. Four signals and four extrapolations project more operators and coordinated AI-enabled campaigns ahead.

Electrek reports that the BUILD America 250 bill would create an annual EV tax—$130/year for BEVs and $35/year for plug-in hybrids, with automatic increases up to $150 and $50; collected by states with potential federal funding penalties for noncompliance. It also cuts funding for EV charging, freight electrification, and disadvantaged communities. Critics call it unfair and ineffective for highway funding, noting gas taxes haven’t risen since 1993 and that EVs pay far more per mile while large trucks do most road damage; they favor mileage/weight-based taxes and pollution pricing.

Baltazar Studios documents a ten‑chapter build of a nibble‑based, decimal‑accurate BCD calculator on an Altera Cyclone II FPGA. The project designs a custom CPU (12‑bit instructions, Harvard memory, 14 ALU ops, BCD adjustments) and a hand‑written two‑pass assembler, plus a scripting layer. It covers numerical methods (addition, multiplication, CORDIC, logs), hardware test framework (Verilator/ModelSim), and a path from dev board to a final PCB with keyboard and display. Verified to 14 decimal digits; runs in desktop (Qt) and WebAssembly. Final device uses ~1,593 logic cells.

The piece argues that Silicon Valley's embrace of AI and proposals for universal basic income (UBI) are self-serving: as automation destroys jobs, tech elites want to preserve demand by giving cash, not sharing ownership. It traces a historical pattern from slavery to contract labor (engagisme) and then to the worker-as-consumer dynamic: to maintain a market for mass-produced goods, workers must be both workers and buyers. In the AI era, widespread automation threatens aggregate demand unless UBI sustains consumer spending. The author proposes that automation’s benefits belong to the public and that ownership should be shared, not privatized.

FBI seeks nationwide access to ALPR data via a SaaS platform, enabling queries by license plate, time, vehicle description, and location across the Eastern/Western 48, Hawaii, Puerto Rico, Alaska, and other territories. The contract could be up to $36 million (six million per region) and may be awarded to a single vendor, possibly two. Likely bidders: Flock and Motorola Solutions (Vigilant/DRN). Flock runs a national ALPR network (~80,000 cameras); ICE and other agencies have accessed it. Motorola’s DRN/Vigilant holds a vast ALPR database. Privacy concerns abound.

Google’s anti-bot block on a YouTube page says unusual traffic from the user’s network triggered a CAPTCHA; enabling JavaScript and solving it is required to continue. Traffic may come from malware, a browser plug-in, or a script; the block will lift once requests stop. If on a shared network, ask the administrator; details include IP and time.
