Explains x86 prefixes and escape opcodes as a flowchart. It covers how instructions are grouped by length into legacy maps (1-byte: map 0; 2-byte: map 1; 3-byte: maps 2/3), with operand types selected by mandatory prefixes (none, 66, F2, F3). It shows promoted legacy instructions (map 4) encoded via EVEX for APX, and AVX-512 (maps 5/6). Prefix families described include REX (1- and 2-byte), VEX (2- and 3-byte), and EVEX (4-byte), plus details of fields that extend registers, operand size, vector length, and instruction maps.

Google blocks access to the YouTube video after detecting unusual traffic from the user’s IP. To continue, the user must complete a CAPTCHA to prove they are not a bot. The block may be caused by malware, a browser plug-in, or scripted requests; on a shared network, an administrator should check. The block ends when traffic stops. CAPTCHA prompts can occur with fast or robotic requests. The message also lists the user’s IP and timestamp.

X-algorithm powers the For You feed on X by merging in-network (Thunder) and out-of-network (Phoenix Retrieval) posts and ranking them with a Grok-based transformer. The system uses Home Mixer to orchestrate stages: Query Hydration (user history and features), Candidate Sourcing (Thunder and Phoenix), Hydration, Pre-Scoring Filtering, Scoring (Phoenix predictions for multiple actions, then Weighted and Diversity scorers), Selection, and Post-Selection Filtering before delivering a ranked feed. Key design: no hand-engineered features, candidate isolation during ranking, hash-based embeddings, and a composable Candidate Pipeline. License Apache-2.0; Rust/Python mix.

An interactive cellular growth simulator. Starting from one cell, cells may grow or split based on adjustable Grow and Split probabilities. Splitting yields a new cell in a nearby direction; a smaller max turn angle makes growth straighter. Only the youngest cells can grow or split; a percentile-based age threshold governs activity. Cells emit signals at birth to mark occupied spots, with higher signal decay speeding regrowth but increasing overlaps. A maximum age kills cells. A 'Show signals' control toggles visibility of emitted signals.

Amazon announced general availability of the AWS European Sovereign Cloud (EUSC), a cloud infrastructure isolated in the EU. The first region is Brandenburg, Germany, with plans to expand across the EU via sovereign Local Zones in Belgium, the Netherlands, and Portugal. It will be operated exclusively by EU residents in the EU, with an advisory board of EU citizens. Data and metadata stay in the EU; it uses its own IAM and billing and EU Route 53 with EU TLDs. Backed by €7.8B investment; expected €17.2B impact by 2040 and ~2,800 jobs/year. Access via aws-eusc; EUR pricing; eight currencies.

F-16 Falcon Strike version 2.0.2 (2026-01-18) by Jarosław 'Roeoender' Wosik. A retro-style Atari XL/XE flight sim featuring the Królewiec Campaign where a Polish F-16 pilot defends the EU border from B.A.R.F. It offers a 15-mission campaign, a WARFARE mode with a procedurally generated battlefield, and a GENERATOR mode for endless missions, plus strategy to defeat air and ground threats on a dynamic 3D battlefield. No AI tools were used in development. Contact details and forum links are provided.

Japan’s SaaS market operates differently: sales cycles are slower, buyers research internally, and leads typically start by downloading product documentation before a demo. Trust hinges on localization, Japanese-speaking support, and strong social proof, especially case studies, since foreign vendors are scrutinized. Website CTAs should prioritize document downloads over immediate demos. Companies should test Japan with low-cost localizations and data-driven signals before full entry. Trade shows can help for market research but are not a sales channel without local presence. Nihonium offers fractional GTM, localization, SEO, and event support to validate Japan without a full subsidiary.

Cursor's autonomous-coding swarm ran hundreds of agents on one project, using planners, sub-planners, workers, and a judge agent to determine completion. They tested building a web browser from scratch, producing over a million lines of code across about 1,000 files. The GitHub repo initially faced skepticism due to failing CI and missing build steps, later fixed. The author built and ran a browser with cargo run; screenshots showed readable pages with rendering glitches. The effort uses WhatWG/CSS-WG specs via submodules. Not Chrome/Firefox/WebKit-scale soon, but surprisingly rapid, echoing a 2029 prediction; a second AI-browser project (HiWave) emerged recently.

Using Node.js AsyncLocalStorage to fix DrizzleORM's limited query logging. Problem: Drizzle’s logger runs before execution and lacks end-time/results; hacks were risky. Solution (three parts): 1) wrapQuery creates a per-call context with queryKey and startTime; 2) Drizzle’s logger pushes SQL/args into that context; 3) after execution, read the context to emit a complete log line with key, duration, SQL, args, and row count. Benefits: type-safe, no prototype hacks or library-internals, minimal overhead. The pattern is used elsewhere (OpenTelemetry, Sentry).

Porsche delivered 279,449 cars in 2025, down 10% from 310,718, with a value-driven mix. Macan led with 84,328 units; 911 51,583; Cayenne 80,886; Taycan 16,339; 718 Boxster/Cayman 18,612 (phase-out). Electrified sales reached 34.4% (22.2% BEV, 12.1% PHEV); Europe 57.9% electrified. North America remained largest market (86,229); China declined to 41,938 (-26%). Supply gaps for combustion 718/Macan and weaker China demand noted. Porsche will expand EVs and customization, focusing on “value over volume” for 2026.

Radicle 1.6.0 Amaryllis is a major refactor release (153 commits by 12 contributors). Highlights include migrating radicle-node to mio for cross-platform I/O, Windows build support, MSRV raised to 1.85, CLI updated with clap and shell completions, systemd credential support for radicle-node, and bootstrapping fixes to skip Tor/IP when unavailable in favor of DNS names. The release modernizes multiple crates, with installation via curl and an extensive changelog.

Reticulum is an open-source cryptography-based networking stack that lets you build local and wide-area networks across LoRa, packet radio, WiFi, and more. It provides end-to-end encryption, initiator anonymity, cryptographically backed multi-hop routing, and flexible multi-medium interoperation, without relying on IP at the core. It runs entirely in userland Python 3 and can tunnel Reticulum over IP if desired. It supports multiple interfaces (Ethernet, LoRa with RNode, Packet Radio TNCs, serial, TCP/UDP, etc.), includes management utilities, and is the reference implementation under the Reticulum License. It is relatively young and not audited.
