A derailment near Adamuz, Andalusia, Spain, killed at least 21 people and injured more than 70 after a high-speed train from Malaga to Madrid derailed and collided with an oncoming Madrid-to-Huelva train. About 300 on the first train and 100 on the second. 30+ seriously injured. Investigation may take a month. Train type Freccia 1000; speeds up to 400 km/h. Madrid-Andalusia services suspended; relatives’ centers set up. Prime Minister Pedro Sánchez expresses sorrow; King and Queen respond; Macron and von der Leyen offer condolences. References a 2013 Galicia derailment.

Shihab Khan evaluates AVX-512 on an image-segmentation K-means benchmark (8 clusters) to compare scalar, auto-vectorized, and hand-tuned intrinsics. Using an AMD EPYC 9654, the theoretical peak is 59.2 GF/s; the workload (~5M pixels, 20 iters, ~200 flops/pixel) should finish in ~337 ms. Results: both AVX2/AVX-512 improve over scalar, but not ideal 8x–16x. Hand-written intrinsics deliver 7–8.5x over scalar and ~4x faster than auto-vectorized. Auto-vectorization lags due to inner-loop vectorization. CUDA mirrors SIMD patterns but adds warp-divergence. Verdict: AVX-512 is promising for performance and programmability; explicit SIMD plus future LLM-assisted porting looks viable.

Rijnard van Tonder introduces the Code-Only Agent: a single-tool approach using execute_code to generate and run code as the sole means to accomplish tasks. It replaces tool-collection with executable witnesses and outputs, offering traceability and guarantees. The piece covers harness design, output handling (thresholds, stdout/stderr), enforcement, and runtimes (Python, TypeScript, Rust, Bash). It surveys future directions: composition, mixed runtimes, Skills, and agent orchestration. Code-Only aims for computable, provable progress where determinism and proofs matter, unlike multi-tool prompts.

The post argues that successful AI agents scale when engineers embed “back pressure”—automated feedback on quality and correctness—into the workflow. Without it, agents that only edit files force constant micro‑management. Providing tools to run builds, read results, and self‑correct lets agents tackle higher‑level tasks while humans focus on strategy. Strong type systems, clear error messages, and feedback channels (MCP/Playwright, LSPs) enhance back pressure; even proof assistants and fuzzing can verify results. Build disciplined feedback loops to stamp out inconsistencies and trust the agent.

This article explores how to contain Claude Code's network access and secrets exposure using sandboxes and proxies. It reviews sandboxing options (Claude Code Sandbox Bash, experimental sandbox runtime, devcontainer firewall, Cursor, Codex CLI) and the limits of network isolation (IP allowlists, TLS/SNI risks, domain fronting). It then explains how to use HTTP proxies (HTTP_PROXY and sandbox httpProxyPort) and mitmproxy with add-ons to intercept or replace the ANTHROPIC_API_KEY, demonstrating how dummy keys can prevent key leakage. Finally, it suggests tying permissions with Formal connectors to enforce fine-grained least privilege and logging, routing API calls through a connector.

The author predicts that within 15 years Microsoft will discontinue Windows and release a Windows-themed Linux distribution that runs Windows apps via Wine. He argues Windows is getting worse while Linux improves, gaming on Linux (AMD + Proton) is strengthening, aided by Valve's Steam Deck. If gamers drive the shift, PCs will ship with Linux, and Microsoft may pursue lock-in through SaaS integrations or patched Wine, but such a strategy is unlikely to succeed because people dislike Microsoft software.

Andrew Lilley Brinker explains Steve Yegge’s Gas Town, an AI agent orchestration tool, and provides a decoder for its opaque terminology. The post translates terms like Town, Workspace Rig, Project Overseer, User Mayor, and agents such as Polecat, Refinery, Witness, and Deacon into more familiar roles (top-level folder, project, user, managing agent, and maintenance/workflow agents). He notes Gas Town remains messy but hopes the glossary clarifies how the agent system operates amid awe and confusion.

Google AI Overviews now answer questions directly on results pages, causing 60% of legal searches to end without a click and a 19% traffic drop in 2025, with 70–80% expected by mid-2026. CPCs have surged (up ~568%), some keywords exceeding $500–$1,000. The traditional “search, click, call” model is collapsing, urban firms hit hardest. The industry is moving to GEO (Generative Engine Optimization): optimize for AI citations, diversify channels (video, brand, community), and capture demand outside search. AI-powered intake (e.g., Talk24) helps firms thrive.

agent-en-place is a GitHub project that builds on-demand Docker containers configured with AI coding tools (Codex, opencode, Copilot) for a given project. It auto-detects tool versions from config files (mise/asdf .tool-versions, mise.toml, idiomatic version files) and generates a Debian 12-slim Dockerfile to run tools in a container. Installation via git, Go 1.21+, or binary downloads; usage defines a vibe() shell function to launch a chosen provider inside the container. It supports codex, opencode, copilot; flags include --debug, --rebuild, --dockerfile. MIT license.

The piece presents Dead Internet Theory: since around 2016 the web is dominated by bots and AI-generated content, making authentic human interaction rare. Through a HackerNews thread about an open-source project, the author notes AI-written code and comments, suspicious patterns, and difficulty distinguishing real people from bots. They warn that as AI becomes ubiquitous, verification becomes impossible and expert review is scarce, risking flawed code and distorted discourse. The end result could be a future where human knowledge is recycled by bots for profit.

Cardputer uLisp Machine is a handheld Lisp computer (ESP32-S3) with a 240x135 display, 56-key keyboard, SD card, and 1.5 MB flash for Lisp workspace. It runs uLisp (a subset of Common Lisp) with ~200 functions, supporting integers, floats, strings, lists, graphics, and simple extensions. The editor has parentheses matching and autocomplete. Firmware is installed via the M5Stack core in the Arduino IDE; Mac USB boot issues are noted. Cardputer-specific extensions include get-key, read-pixel, and save-bmp; source is on GitHub.

Facing AI overload, a growing movement seeks an analog lifestyle to slow down and reclaim tangible tasks. Offline hobbies are booming: Michaels reports 136% more searches for analog crafts and an 86% rise in guided craft kits in 2025, with yarn kits up 1,200%. CNN's Ramishah Maruf tries living like the '90s for 48 hours, ditching devices, using a landline and film photos, and joining knitting circles. Proponents say going analog cuts doomscrolling and data exposure, not technology, while many still keep some digital habits. It’s a broader cultural shift toward mindful, hands-on living.

Stirling Cycle Machine Analysis is a self-contained learning resource by Israel Urieli offering MATLAB-based simulations for single-phase piston/cylinder Stirling machines. It extends the 1984 Stirling Cycle Engine Analysis book with updated MATLAB m-files (from FORTRAN) for thermodynamics, heat transfer, and friction, including ideal isothermal and adiabatic analyses and a simplified heat-exchanger model. It covers Alpha machines (Sinusoidal drive, Ross Yoke/Rocker-V), various heat exchanger types (tubular, annular gap, slot) and regenerator matrices (screen mesh, rolled foil), and working gases (air, helium, hydrogen).
