Twenty-day, parallel, double-blind RCT in 40 adults with pre- to stage 1 hypertension compared twice-daily peppermint oil (100 μL/day; 50 μL in water, 2× daily) with a peppermint-flavored placebo. The primary outcome: between-group SBP change at 20 days. Peppermint reduced adjusted SBP by 8.5 mmHg (95% CI −14.2 to −2.7; p=0.005; d=−0.94); DBP fell by 4.6 mmHg (p=0.043) and resting HR by 8.9 bpm (p=0.041). No significant differences in body measures, lipids, glucose, sleep, or psychological outcomes. High compliance; one mild adverse event. Possible mechanism: menthol-mediated TRPM8 vasodilation and NO signaling. Longer trials needed.

A syslog server collects, stores, and analyzes log messages from devices. It handles event generation, transmission (UDP/TCP/TLS), reception, storage, parsing, indexing, and search/analytics. Core components: log receiver, parser, storage, search engine, and alerting dashboard. Logs follow a standard format with priority, timestamp, host, process, and message; eight severity levels and multiple facilities. Benefits include centralized logging, faster troubleshooting, security monitoring, regulatory compliance, and automated alerts. Best practices: TLS, synchronized time, retention, restricted access, storage monitoring, and backups. Challenges: storage needs, volume, noise, parsing, and scaling. Syslog vs SIEM: SIEM adds analytics. Future: cloud, AI anomaly detection, containers, and analytics.

Author upgrades a GMKtec NucBox G9 with four additional 2.5GbE NICs (Intel I226-V) using two m.2 B+M key adapters, and a 3D‑printed bottom shell replacement to mount the NICs and two 40mm Noctua fans. The project required CAD tweaks (via Claude) to fit, ensure cooling, and clean routing of cables. They document a disaster‑recovery workflow: OpenWrt backups to NAS via dd/gzip, then boot Alpine from USB to restore the latest backup to internal eMMC, keeping WAN stable by MAC mapping. Plans and BOM are on Printables.

The article argues that classic Bezier curves are legacy and can be improved by editing curvature instead of tangent length. It explains Bezier construction and shows symmetric tangents do not guarantee smooth curvature, proposing curvature-based handles whose lengths encode start/end curvature k0, k1. It derives a quadratic system to solve for tangents l0, l1 from k0, k1, solves a quartic, and uses a weighting heuristic to pick stable solutions for smooth edits. It covers UI implications, conversion between curvature handles and Bezier controls, and notes edge cases like S-bends and inflection points.

GlassBox is a client-side browser fingerprint bench that runs live fingerprinting probes in your browser to reveal what signals sites can collect. It tests engine/hardware canvas, audio, fonts, codecs, and signals; identifies browser build; and tracks session state like theme and timing. IP/geolocation is queried by default (toggle off to stay local). Results show raw values, identifiability ratings, and comparisons with saved reports or JSON from other sessions. Probes stay in your browser (no analytics); the model notes that combined signals can uniquely identify a browser, especially for signals like canvas, WebGL, and fonts. Tor crowds may mask identity.

Nvidia is exploring CUDA on RISC‑V, but only on server‑grade hardware. They specify RVA23 CPUs and RISC‑V server platform requirements, including RAS features, a security processor, ACPI, and PCIe coherency with cache coherency and peer‑to‑peer PCIe. CUDA would avoid performance penalties by relying on these features, e.g., vector extensions and predication. ACPI was a sticking point but has been added via RISC‑V specs. NVLink Fusion would allow third‑party CPUs to use NVLink C2C with CUDA, DOCA, NCCL, and close partnerships. In practice, consumer RV hardware likely won’t meet requirements soon; server systems first.

Security researcher Alex Schapiro disclosed a GraphQL authorization flaw in Beam Living (a Blackstone portfolio) that exposed applicants’ PII—including last-four SSN digits, date of birth, addresses, emails, phone numbers, IPs, and more—for anyone with an email via a shared leasing portal across Beam Living communities. The tester used a friend’s account to confirm the leak. After repeated follow-ups and little response, Beam Living patched the flaw silently. Schapiro criticized the disclosure process and published after a window to respond. Timeline covered mid-June to July 9.

Mozilla plans to enable JPEG XL decoding by default in Firefox 157 on all platforms, moving from the image.jxl.enabled flag. The decoder is jxl-rs (Rust); ISO/IEC 18181 standard. Safari 17 shipped; Chrome behind a flag. Since prototyping, jxl-rs 0.6.0 adds multithreaded decoding; early benchmarks show Firefox slightly ahead of Safari on large images, with parity on other formats and better HDR tone mapping; Safari lacks progressive rendering and animation. Web Platform Tests and Gecko tests cover decoding correctness; fuzzing will occur before flipping the pref.

InferQuest is a free, open web app that teaches inference engineering and LLM training through two tracks: Inference Engineer (fast, cheap production serving) and Training Engineer (best results on minimal hardware). The curricula are organized into quests and tasks with 182 tasks across 38 quests, plus a shared Foundations trunk. Progress uses XP, levels, drills, and streaks, with auto-verification for milestones via live endpoint probes, GPU-kernel/training evaluations, and merged-PR checks. It’s all open, no certificate, and milestones serve as receipts. GPU required for kernel phases; otherwise CPU/free cloud support.

Low-tech Magazine asks if the Netherlands could be dredged without fossil fuels. Historically dredging used hand labor, animal, wind and tide power; later fossil-fuel ships dominated. Today 30–35 million m^3 of mud are removed annually, with Rotterdam about 20 million, as bigger ships require deeper waterways. Techniques ranged from hand dredging with dredge bags to dredge mills, horse-powered mills, valve barges and wind-powered scratchers. Friesland’s small-draft skûtjes reduced dredging needs. A workshop tested hand dredging and assessed labor requirements, suggesting solar/wind dredging is impractical and outlining the scale of manual options.

Baez surveys whether exceptional algebraic structures can naturally explain the Standard Model’s three generations. Building on work that ties the SM gauge group to the exceptional Jordan algebra and extending to Jordan pairs from bioctonions, one generation arises naturally, but three generations remain unachieved. A larger exceptional Lie algebra (Bokor) offers a threefold symmetry that could permute generations, yet this is still a mathematical pattern, not a physics theory (no spin, no Higgs, no Lagrangian). He also discusses AI-assisted writing and his preference for future human collaboration.

NetBSD's Google Summer of Code 2026 report describes adding N-way RAID 1 to RAIDframe, enabling more than two disks in a mirrored array, plus implementing RAID scrubbing. Previously RAIDframe supported RAID 0, 1, 5, 6 but had RAID1 limited to two disks, no scrubbing, and limited testing for RAID6. The project introduces N-way RAID1 with one primary and multiple secondary disks, dynamic PDAs, DAG-based I/O, and reconstruction changes to handle varying parity disks. Configured via raidctl(8); tested across multiple layouts. Benefits include increased redundancy; future work: validate other RAID levels and acknowledge the mentor.
