IEEE Spectrum covers MicroVision’s Movia S solid-state lidar, targeting production pricing under $200 per unit (potentially $100 with scale). If realized, lidar could reach ADAS beyond niche autonomous programs. Solid-state designs promise major cost cuts from mechanical lids ($10k–$20k) via high‑volume manufacturing, but offer smaller fields of view (~180°) and may require 3–4 sensors per car for full coverage with complex data fusion. Lidar would augment cameras and radar rather than replace them; adoption depends on system‑level cost and demand.

Terence Eden revisits the EU IST Advisory Group’s “Ambient Intelligence in 2010” scenarios to see how close 2026 is to that vision. He covers Maria (near-term wearables and smart environments), Dimitrios and his D‑Me (digital avatars), Carmen (traffic, shopping, and smart delivery), and Annette/Solomon (ambient-assisted learning). Some elements exist: GPS, ride‑sharing, video with translation, smart lockers, digital keys, and voice cloning. But full ambient intelligence—with seamless privacy‑aware integration and fully trusted ambient agents—remains distant. Five tech requirements are key: unobtrusive hardware, seamless infrastructure, distributed networks, natural interfaces, and dependable security. Progress hinges on open standards and public investment.

Wrote a minimal Python/Pygame UI framework for rapid experimentation. Initial brute-force approach used a flat component list with a per-frame loop (hit-test, update, render), which was impractical for general tools. Evolved to a tree-based layout engine with nodes, measure() and distribute(), using depth-first traversal and intrinsic sizing only (no constraints). Added asynchronous support with main-thread callbacks, global event listeners, and performance optimizations via dirty flags. Implemented UI stages as a navigation stack. Future ideas: declarative APIs, better composability, and customizable styling (Tailwind-like). Concludes the project teaches more about UI systems than standard solutions, despite imperfections.

Wildfire Games released 0 A.D. Release 28: Boiorix, the 28th free open-source RTS named after the Cimbri king. The game remains GPLv2 for code and CC-BY-SA 3.0 for art. Release 28 is the first without the Alpha label, aiming for more frequent updates and inviting volunteers in video, social media, design, QA, translations, and development. A new Germans faction adds semi-nomadic Cimbri/Teutones-style civ with Wagon Trains, Migratory Resettlement, and siege units. Other changes: Gendered Civilians, Direct Font Rendering, new setup options, lobby security, 64-bit Windows default, AppImage, and engine updates. See the wiki for full changes.

Queues serve as buffers, not throughput boosters. They absorb bursts and timing differences between producers and consumers, but cannot compensate for higher arrival rates. For batch workloads, queue size can match data volume; for real-time systems, size should reflect latency limits via Little’s Law: queue size ≈ arrival rate × latency. Real-world factors (GC, CPU, I/O) bias this, so monitor queue depth, set alerts, and timestamp messages to measure service time. Use back-pressure or retries when latency constraints are breached.

This post on The Lexicans by Bill Brandt introduces and aggregates Carroll "Lex" LeFon's long-running Rhythms the Compendium—a multi-part, first-person portrayal of life aboard a U.S. Navy aircraft carrier. It lists the 50+ chapters (Part I to Part LIV) detailing daily operations, flights, refueling, combat drills, emergencies, and personal reflections, aiming to give readers an insider cockpit-to-bridge view. The author explains he re-posted Lex's writings from 16 years ago to preserve his legacy and guide readers through Lex's "Rhythms" as a connected compendium, with links and context on Lex’s blogs.

OxC (JavaScript Oxidation Compiler) is a Rust-based suite of high-performance JS tools: Oxlint (ESLint-compatible linter with true type‑aware linting), Oxfmt (Prettier-compatible formatter with Tailwind sorting), oxc-parser (fast JS/TS parser), oxc-transform (TS/JSX to ES2015 transpiler), oxc-resolver (Node CJS/ESM resolution), and oxc-minify (minifier with dead-code elimination). Claims 50–100x faster linting, 3x faster formatting and parsing vs alternatives, all open source with sponsors. Guides and docs available.

RiSE MSR's post describes A3-python, an agentic, proof-oriented verifier for Python built by Halley Young and Nikolaj Bjørner. It combines AI-driven theory discovery with formal verification, using barrier certificates (Positivstellensatz, sums of squares) and a kitchen-sink cascade of barriers plus directed symbolic execution (DSE) to prove safety or find real bugs. On real codebases (requests, PyTorch Adafactor, DeepSpeed, LLM2CLIP) it eliminates most bugs as false positives and yields a small set of true positives, with AI mainly used for planning and iteration. The system aims for language-agnostic verification with symbolic-neural triage, reproducible in CI.

Agentic Software Engineering outlines a future where autonomous AI agents reshape how we build, test, and deploy software, shifting from coding to architectural thinking. It includes a 27-minute AI-generated audio summary and an online book with a downloadable PDF. Key takeaways: the real bottleneck is complexity, communication, and maintaining system integrity over time. The discipline focuses on reliability and trust between stochastic AI and human contributors. Success goes to teams that set clear intent, manage risk, and demand evidence rather than just fast typing.

Aqua is a CLI tool for AI agents enabling peer-to-peer, end-to-end encrypted messaging with durable storage. It uses Circuit Relay v2 for cross-network connectivity and provides a simple CLI to manage nodes and messaging. Installation options include a prebuilt binary or go install. Quick-start demonstrates creating IDs, adding contacts, sending messages, and reading inbox. Relay-mode auto tries direct connectivity then relays. Official relay endpoints and commands (init, id, contacts, serve, relay, hello, ping, send, inbox) are documented. Default data directory is ~/.aqua. See SKILL.md for AI agent skills.

Musidex is a physical Rolodex-like collection of favorite albums linked to streaming playback. Each card shows album art, title, artist, year, plus a QR code for streaming and an NFC tag to trigger playback on home speakers. Two versions exist: Musidex I (self) and Musidex II (dad), ~300 pages each with ~600 albums; highly curated (one album per artist) with some blanks or playlist links. A workflow used scripts to pull art/metadata from iTunes and streaming playlists, plus manual curation and some mismatches. It hints at other tangible-digital Dexes.

An alternate timeline where the microwave replaces the stove is explored via Marie T. Smith’s 1985 Microwave Cooking for One. The piece explains microwave physics, required cookware, and exact timing, then experiments with recipes (steak, onions, eggs), showing mixed success and even a few explosive mishaps. It argues microwaving stayed low-status and counterintuitive, limiting broad adoption despite Smith’s decade of hands-on testing and a for-one culinary philosophy.

Rituals, defined as formal, repeatable sequences with symbolic meaning and no direct instrumental purpose, help people cope with uncertainty by signaling constancy. Across cultures and history—from Papua New Guinea fishermen to 70,000-year-old Botswana cave rites—rituals reduce anxiety and can improve performance. Experiments show pre-performance rituals lower heart rate and anxiety; Hindu women in Mauritius and star athletes like Rafael Nadal use ritual structures for focus. Rituals also strengthen social bonds, though they can fuel inter-group bias and harmful hazing. Adopting personal or group rituals can provide stress relief.
