jevotron is a command-line anomaly-detection tool that scores fields in data entries using shared guidance, enabling one-shot scans. Provide a file, set an API key, preview, scan, and review results; results include per-field and entry scores, stored in SQLite for reuse. It supports CSV, YAML, JSON, TOML, text, OBO, and gzip, with options like --field, --guidance, and --guidance-file; a local Python config is available. Examples cover airports, inventory, measurement units, and agent traces; the 'measured pilot' demo reports precision/recall metrics.

California has banned child marriage, setting 18 as the minimum age and taking effect January 1, 2027. The law ends a system allowing minors to wed with parental consent and a judge’s approval, and it removes a path to divorce for under-18s. About 9,000 girls wed each year in California, many in abusive situations, according to advocates. Survivors like Brittany Bee and Sara Tasneen welcomed the change. California is the 18th state to ban child marriage since 2018, while 32 states still permit it.

Financialisation of food shows how markets securitize surplus—parmesan as bank collateral and Quebec’s maple syrup reserve—to manage accumulation, price volatility, and climate risk. Such fixes can ease shortages but deepen inequality by widening the distance between producers, workers, and consumers and by shifting risk to ecosystems and labor. Climate change threatens storage-based arrangements; automation and blockchain intensify resource use and labor displacement. The author argues these measures are a band‑aid that preserves a capitalist, unequal food system rather than solving it.

Public records show the Trump-era HIDTA program funnels local license plate reader data from ALPR vendors (Flock, Axon, etc.) into federal surveillance hubs. Using anti-drug funding, HIDTA aggregates data on federal servers and sometimes shares it with the DEA’s National License Plate Reader Program, making it accessible to multiple agencies beyond those with ALPR contracts. MOUs in Georgia and elsewhere require cities to send data to HIDTA. Privacy advocates warn this circumvents local control and FOIA, creating opaque, multi-agency surveillance with broad retention.

Yantra is a C++-based parser generator with an integrated lexer, AST builder, and AST walker. It uses LALR(1) bottom-up parsing followed by a top-down AST walk, supports multi-mode lexing and Unicode, and can emit either an amalgamated single-file parser or separate .hpp/.cpp files. It builds a self-contained ycc tool from a grammar (e.g., hello.y, calc.y) and compiles with any C++23 compiler. Yantra emphasizes full AST construction before actions, contrasting with Bison/Yacc, ANTLR, and tree-sitter. MIT-licensed; author Renji Panicker.

pldb is a searchable database of programming languages papers, spanning 1973–2026, aggregating 33,580 papers (26,107 with abstracts) from venues such as POPL, PLDI, ICFP, OOPSLA, ECOOP, ESOP, ICSE, TOPLAS, JFP, and more. It provides venue-based counts and timelines, metadata from dblp (CC0) and abstracts from SIGPLAN OpenTOC, OpenAlex, and Semantic Scholar. Users can filter and search by topics (e.g., gradual typing, separation logic) and authors. It is a public bibliographic resource for PL research.

Explores Australopithecus africanus from its disputed 1920s discovery to status as evidence of Africa’s early humans. It covers Piltdown Man, a fraud that misled researchers for decades about human origins in Europe, and Dart’s Taung Child, which faced European skepticism but was later vindicated by Robert Broom’s finds at Sterkfontein and Kromdraai. By 1953 fluorine dating debunked Piltdown; African fossils showed early hominids lived in Africa. A. africanus, 3.2–2 million years old, was bipedal with a mixed diet; its place in ancestry remains debated.

56k.rip recreates a 1996 dial-up experience in the browser. You start at a desktop, dial up, and a page arrives byte-by-byte at a chosen speed (14.4/28.8/56k). Images load line-by-line, downloads stall, and calls can drop. Behind the modem is a mini 1996 service with pages like fishing, recipes, guest book, webring, classifieds, missed connections, weather, and an “internet” article, plus mail, chat, games, paint, a command prompt, and screensavers. Sounds are browser-generated; the handshake is a real modem recording. Everything is client-side; no accounts or server storage. JavaScript required.

EDG Compiler Project is an open-source C/C++ front end with strong parsing compatibility and bug emulation to ensure code that compiles under Clang, GCC, or MSVC also compiles with EDG. It includes a C and C++ back end, a prelinker, a minimal runtime, utilities for the intermediate language, a name demangler, and development tools. Documentation and build/contributing guides are available (docs at edgcpp.org). Partial clone is recommended for building; see contributing and development guides for setup. The repo provides license, contributing, and project information.

Groundrun enables hardware-in-the-loop automated testing of ESP32 Wi‑Fi setup across five methods: Bluetooth, Soft AP, captive portal, SmartConfig (ESPTouch v2), and WPS. Using an ESP32-C6 devboard and an Android phone connected to a Groundrun rig, they built a minimal app (one button per method) and had Claude generate firmware for the flows. They ran interactive and CI regression tests, timing phases (Flash/boot, app install, AP setup, mechanism, wait). Findings: flash/boot ~22–24s; mechanism times vary; Soft AP and captive portal slowest; WPS fastest; SmartConfig slower with rare failures. Groundrun enables reliable Wi‑Fi setup testing.

Lathoa is a critical-thinking app for ages 10–14 that trains kids to spot wrong AI reasoning in math using Errol, a deliberately incorrect tutor. Students review Errol’s step-by-step solution, tap the mistaken step, and write a short explanation before seeing a correct solution. The aim is to learn to question AI, not just get answers. Features include calibrated wrongness levels (Obvious–Expert), no grades, a rank ladder (Rookie to Sherlock), replayable case files, COPPA-safe, ads-free, and flexible pricing with free trials and family plans. Subjects span arithmetic to early geometry; school licenses are available.

The article explains Coltrane’s Tone Circle, a diagram overlaying the circle of fifths with chromatic rings to reveal harmonic shapes behind jazz harmony. It covers the circle of fourths, the Nashville notation, and how quartal relationships underpin 2–5–1 progressions, tritone substitutions, and Coltrane Changes (Giant Steps). It identifies symmetric shapes on the circle—diminished 7th 'squares', augmented-triad 'triangles', whole-tone 'hexagon', and octaves 'pentagon'—and how modes map around it. It notes uncertainty about Coltrane’s intent and invites exploration.

The piece reacts to Marques Brownlee’s video about YouTube's rumored A/B video variants. It highlights questions about whether viewers and commentators are seeing the same version, and how linked timestamps would work. It argues the feature could fracture the shared viewing experience that makes YouTube culturally coherent. It also distills takeaways for software makers: focus on storytelling and finishing work over chasing metrics; avoid endless variant testing; stand by creative choices. The post links YouTube’s insecurity and competitor focus to the urge to ship such variation features.

Secret hitchhiker ELINT satellites launched on HEXAGON in the 1960s–70s evolved into URSALA, RAQUEL, and FARRAH under the NRO’s Mission 7300. URSALA (2–12 GHz) searched radar side lobes for tactical data; RAQUEL (4–18 GHz) did directed, high-detail ELINT. FARRAH units merged general search with electronic order-of-battle data (2–18 GHz), grew into large 'tuna can' platforms for shuttle and Titan launches, and added on-board processing and direct downlinks to mobile ground stations and ships. Later, LORRI, GLORIA, and CARRIE extended high-frequency surveillance. By the 1990s, Mission 7300 and related programs waned; 7100 ended 2008; 7300 legacy informs modern satellite intelligence.

Quarry is a TUF-based client and publishing tool for distributing immutable images built with tine. It serves static blobs over dumb hosting, enabling autonomous, granular, need-to-know updates with per-machine repositories and cross-repository links. Using The Update Framework (TUF), it separates root, timestamp, snapshot, and targets roles for resilient key management and supports multiple owners and key escrow. It integrates with systemd-sysupdate as a minimal installer and adds extensions for repository listing, cross-repository links, and per-machine repositories to improve mirroring and security.
