US Federal Reserve raised rates for the first time in over three years, lifting the target range to 3.75%–4% from 3.5%–3.75% in a unanimous decision. Fed Chair Kevin Warsh said inflation remains too high and the move is sober and responsible. The hike will make borrowing more expensive but aims to curb inflation; policymakers expect further increases to around 4%–4.25% this year and possibly up to 4.25%–4.5% next year, with cuts not until 2028–2029. Mortgage and credit costs could rise; banks lifted prime lending to 7% from 6.75%. Inflation remains above target; global peers tightening too.

Jake A. Smith deprecates his 2014 174-line PHP shim for http_build_url, a temporary fix that has been installed nearly 20 million times via Packagist and bundled in WPML, idna-convert, SPIP, and Debian/Ubuntu. What started as AOL CMS upgrade help became a widely used polyfill; a trailing-slash bug and lack of maintainers highlighted risks. With PHP 8.5 shipping a native URI API and newer libraries, he retires the package and will not issue fixes. The install will remain, but unmaintained; AOL CMS migration remained incomplete.

cloudflare/security-audit-skill is a coding-agent skill that turns a codebase audit into a multi-phase security audit using independent sub-agents. It orchestrates six phases: Reconnaissance, Coverage-led hunting, Candidate validation, Structured output, Independent record verification, and Target-neutral reporting, producing machine-readable findings (findings.json, report-schema.json) and reports (REPORT.md, NEEDS-VALIDATION.md). The repo includes phase docs (RECONNAISSANCE.md, HUNTING.md, etc.), validators, and setup instructions via npx skills add. It supports full audit mode or guidance mode, requires a sandboxed Node.js environment, and emphasizes adversarial validation and traceable evidence. It seeded Cloudflare's vulnerability harness.

Jev Ultrafast is a browser agent with a dynamic action space that reaches a goal by choosing an operation (CLICK, TYPE_TEXT, SELECT, SCROLL, WAIT, DONE) and a target; a small LLM writes text only for TYPE_TEXT, with one decision per browser snapshot and outcome verification. Demonstrations include Zürich–London flights on Google Flights in about 7.1s and opening a Wikipedia Gödel article. To run: clone, set TYPESAFE_API_KEY and TEXT_MODEL_API_KEY, run uv, and open http://127.0.0.1:8766. The repo emphasizes DOM-reading, one browser call per snapshot, and MVP limitations.

The article surveys malloc architecture, focusing on arena-based allocators to mitigate multithreaded heap contention and NUMA locality. It traces memory allocation evolution from stack to per-thread local allocation buffers (TLABs), epoch encoding, and the arena concept, detailing frontend/backend roles. It compares major allocators (dlmalloc, ptmalloc, glibc malloc, jemalloc, tcmalloc, mimalloc, Hoard, snmalloc, nedmalloc, phkmalloc, libumem, mtmalloc) across thread-safety, per-thread caches, NUMA-awareness, fragmentation, and CAS contention. It provides a decision chart and workload-specific recommendations (small objects, large objects, NUMA, security) and notes trade-offs and performance implications, with references.

An engineer tests Fable 5 AI to autonomously design a compact PCB that drives a 1.54" E-ink display from a Raspberry Pi Pico with four buttons, I2C, and GPIOs. The process starts with failures (Claude-generated footprint mismatches, 65 DRC errors) and ends with a working board after switching to the P25Q64SH flash, routing with KiCadRoutingTools, and ordering from JLCPCB. The finished boards (5 assembled) work: stopwatch, e-reader, image album, and menu navigation. The author reflects on automation’s lure and loss of hands-on learning, plans future AI-assisted projects (Jetson Orin Nano tablet).

Vanity Fair’s 2008 exposé portrays Monsanto as a powerful, aggressive patent enforcer in U.S. farming, using investigators and lawsuits against farmers, co-ops, and seed dealers to curb “seed piracy” and protect GM patents. It traces Monsanto’s shift from a chemical giant to a biotech leader, while detailing its environmental legacies—PCB and dioxin contamination in Nitro and Anniston—and health concerns. The piece also covers its push into dairy hormones (rBGH), labeling battles, and political ties, suggesting a growing public backlash and a trend toward non-rBGH products.

WatchTowr analyzes CVE-2026-32746, a pre-auth RCE in GNU inetutils Telnetd via a LINEMODE SLC buffer overflow. The overflow of a small slcbuf allows targeted writes; exploitation is highly environment-dependent and more feasible on 32-bit systems (notably Debian 32-bit) than 64-bit. The vulnerability spans many distros and forks; patches exist but not widely deployed, and even inetutils 2.7 remains vulnerable. The researchers demonstrate detection artifacts and a minimal overflow probe. Telnet remains used in some devices, so immediate patching is advised.

mapsnap automates georeferencing of historic Sanborn Insurance Maps. It OCRs a map to detect street labels (EasyOCR), filters to real city streets, and uses the labels to propose candidate intersections. Intersections paired with OpenStreetMap coordinates become Ground Control Points. With two or three GCPs, mapsnap computes a georeference; a robust RANSAC-style loop tests many GCP pairs and keeps the fit with the most inliers, tolerating noisy reads. Limitations occur when street names are short, streets curve, or streets have changed. The aim is 90% page coverage in the LoC Sanborn collection; code available.

US researchers engineered mice to develop human brain cells by implanting human-derived organoids into mouse brains, creating a partly human cortex that connects with the mouse tissue. After months, human cells began to resemble the outer brain layer and the animals behaved largely like normal mice in basic tests. The aim is to study human brain disorders—such as epilepsy, autism and cerebral palsy—more accurately and improve drug testing for psychiatric and neurodevelopmental diseases. Ethics and welfare concerns were raised about altering animal cognition, and some experts cautioned the model may have limited usefulness.

DeepSeek-V4.1 Flash pushes extreme KV cache compression for ultra-long contexts (up to 1M tokens) with multimodal 552B parameters. It reaches ~420 tokens/s and 4x KV compression using FP4 for main KV cache. The model uses a Causal Encoder-Decoder (CED) where the Decoder's global KV is projected from the Encoder to enable reuse. CSA2 cross-layer KV/index reuse compresses across encoder/decoder layers; modes Full, Reindex, Reuse govern KV, indices, and queries. HSI (Hierarchical Sparse Indexer) and bounded Replay reduce decoder compute. Engram memory and DSpark further boost efficiency. KV per token ~890B.

Wind propulsion is re-emerging in commercial shipping as a complementary technology. Modern systems—rotor sails, rigid foils, eSail and suction devices—are installed on bulkers, tankers, containerships and LNG carriers to cut fuel use. More than 100 large merchant ships with wind propulsion are in service or planned, totaling over 5 million DWT. Maersk will test a 35-meter rotor sail on an 8,700-TEU containership in 2027. Vale’s Sohar Max has five 35-meter rotor sails. LNG carriers and ro-ros are under study; wind propulsion is being integrated with engines and voyage planning, despite wind variability and regulatory hurdles.

Destroy After Reading traces the enduring appeal of distressed textures in design, especially heavy metal graphics, to their origins in cheap, imperfect physical media. Avery Robinson maps a history from late-70s/80s underground tape culture (zines, photocopied flyers) through the photocopier-driven grain of the 90s and the digital era, arguing the gritty look signals authenticity, battle-worn character, and history. Divided into three parts, it urges designers to embrace grit as a core design language, not just a visual trick. The page also outlines True Grit’s asset licenses.
