Researchers show ntoskrnl-rs, an NT-shaped kernel written by AI (Fable 5) in Rust, booting in QEMU and passing self-tests after a 38-minute run. The core implements OS components (scheduler, memory, I/O, object manager) and later loads Windows drivers and unmodified binaries in kernel and user mode, forming a testing sandbox. The article argues AI-authored kernels reveal trust boundaries and foreground the verification gap: exhaustive concurrency tests, Miri, proptest, and formal verification are needed before such code can be trusted as a TCB. It warns that rewriting critical infrastructure in Rust is possible but requires robust verification and auditable pipelines.

Hydroponic Trash argues that the corporate internet and AI-driven standardization push people toward analog, handmade tech (cyberdecks) and physical media. It links today’s cyberdeck renaissance—driven by women and marginalized groups—to historic medieval guilds, Luddites, and the Arts and Crafts movement, framing tech as a tool that can either exploit or empower. It urges anti-capitalist, permacultural approaches: reuse/upcycle hardware, extend device lifespans, reduce reliance on money, foster mutual aid, resist platform co-optation, and reimagine an economy oriented to human flourishing.

The piece surveys embedded Linux build systems and argues that traditional tools (Buildroot, OpenEmbedded/Yocto) are strained as edge devices become cloud-like, languages diversify, and cross-compilation grows brittle. It highlights small teams' needs and the limitations of current tooling. The author prototypes a next-gen build system for embedded Linux (the [yoe] build) that uses modern language ecosystems, AI-assisted tooling, build caching, and cross-platform base distros to speed delivery and reduce reliance on lengthy cross-compilation, while noting Yocto still serves regulated, reproducible cases.

An outspoken critique of smart glasses as a fashion dead-end driven by a few tech leaders. The author traces AR eyewear from Google Glass to Meta Ray-Ban and Apple Vision Pro, arguing that despite hype, the devices remain ugly, have short battery life, privacy drawbacks, and questionable usefulness. The piece suggests the real draw is recording potential rather than utility, and laments the persisting trend among Silicon Valley CEOs, with Tim Cook's Vanity Fair outing cited as emblematic. Overall: unlikely to reshape everyday computing.

PivCo-Huffman proposes a parallel Huffman coding/decoding method that treats decoding as a bottom-up merge of symbol lists guided by the bitstream, enabling data-parallel implementations on CPUs/GPUs. The post details a practical merge kernel: 8-byte chunks with a 256-entry index-table, and a 16-byte version using two tables and tricks to share indices between L and R halves. Hardware targets include AVX512_VBMI2 (best), AVX2/SSE, and NEON/ARM, with trade-offs around prefix sums and table sizes. The approach is hardware-dependent but promising, requiring wire formats that support wide parallelism.

Spur Intelligence scanned 6,038 LG webOS and Samsung Tizen TV apps and found 2,058 embedding residential proxy SDKs to monetize the TV’s internet access. TVs are ideal proxy hosts: always on, rarely audited, with consent prompts easy to overlook. SDKs often run after the app closes, and some apps frame proxy use as an ad-free option. Major vendors Bright Data, Massive, and Oxylabs appear as publishers in many cases, sometimes via wrapper apps. Amazon bans such software; Roku reportedly blocks it; LG/Samsung lack a clear policy. Risks include local-network exposure (routers, NAS, printers). Calls for transparency and platform oversight.

Acquired's Spring 2026 Episode 4 traces The Walt Disney Company's rise from Walt's bold bets (Snow White, Fantasia) to Disneyland and a broad IP-driven empire. It argues Disney perfected a flywheel-like model—merging art, commerce, and engineering—to monetize nostalgia at global scale, creating an enduring entertainment conglomerate. The episode cites biographers and histories (Gabler, Barrier, Thomas, PBS) and presents Disney as a case study in the fusion of creativity and business, with podcast-style disclosures typical of the series.

A Holiday Hills, IL police chief and other officials used Flock's license-plate reader to track six people he knew romantically, prompting official misconduct charges. The pattern shows LPRs track people, not just cars, contradicting Flock's claim. Advocates urge warrants for routine stored LPR data; courts already require warrants for GPS, cell-site data, and wiretaps. The cases, including high-ranking officers, underscore the need for warrant-based oversight of powerful tracking tech.

Canyon's Stingr Smart helmet is a HUD-enabled helmet built with Canyon Predict safety. It features a retractable visor that projects road hazards, other road users, group dynamics, and riding-advice into the peripheral vision, with configurable alerts via haptics and on-screen prompts. It can display speed, distance, cadence, power, elevation and heart rate, and can ingest data from a smartphone or Bluetooth/ANT+. Voice commands or external buttons control visor deployment, while it can operate standalone or with the Canyon Predict bike. The aim is to reduce cognitive load and improve rider safety.

Japan relies on wordless graphic symbols embedded in everyday life to convey complex status and needs without speech. Kamon (family crests) and transport marks identify service levels, roles, or affiliations—from government emblems on police cars and snow-crystal fire symbols, to tokkyū limited-express logos on trains. Driver marks (new, elderly, hearing-impaired, disabled) and transit marks (Help Mark, maternity mark) guide behavior without words. This system stems from "reading the air"—anticipating others' needs and fostering mutual consideration in public spaces.

Global memory shortage driven by AI demand is pushing buyers toward legacy DDR2/DDR3, raising prices and inflating PC costs. TrendForce notes RAM makers prioritizing high-margin HBM/server DRAM, reducing mainstream supply. DDR2 contract prices could rise 55–60% in Q2 2026, with another 35–40% in Q3. Manufacturers are only slowly expanding capacity: Winbond reducing DDR2 output, ESMT maintaining current allocation. SK hynix plans to double wafer output in five years; Micron expects meaningful capacity at its Virginia fab in 2027–28. Some devices are being redesigned to DDR2/DDR3 to cut costs.

British Columbia moved to year-round Pacific Daylight Time (UTC-7) in 2026, making Vancouver time fixed and highlighting how timestamptz stores UTC and converts with current tz rules, which can shift times after tzdata updates. If tzdata updates, dates like 2026-11-10 10:00 local may become 11:00. The article recommends a dual-column pattern: local_time (wall clock), timezone_name (IANA), and starts_at_utc (computed UTC) via triggers to preserve user intent. RFC 9557 is not yet adopted or a solution for future-local times. If tzdata changes, plan migration, notify users, test, and recompute.

Linux Secure Boot faces expiry of the Microsoft-signed 2011 key (Sept 2025), which authenticates the shim bootloader. After expiry, installers may need a shim signed with the 2023 MS key; many systems lack that key or firmware updates to install it. LVFS/fwupd can push KEK, db, and related updates via firmware updates to add the new key, but success varies and issues like efivar space can hinder updates. If vendors don’t provide updates, Secure Boot may need to be disabled to install or boot. The situation is evolving across hardware, firmware and distros.

Selector Forge is a standalone browser extension (Chrome & Firefox MV3) that helps you build robust CSS or XPath selectors using AI. You pick elements on a live page; the extension captures context, sends it to a backend that proposes and ranks candidate selectors, and re-verifies each candidate against the live DOM. It supports single-element and list selections, with the browser as the source of truth. It currently uses Intuned for authentication and selector generation; future plans include a self-hosted backend and broader automation. MIT licensed.
