VisualJJ is a VS Code extension that overlays Jujutsu (JJ) and Git with an interactive change tree. It helps you view and edit commit history safely, drag-and-drop commits for rebases, and keep history clean even on busy main branches. Conflicts appear in the change tree in a safe draft state, guiding you through step-by-step resolution. It also integrates with GitHub to track pull requests from the editor and create PRs with a click. Designed to keep developers in flow and streamline in-editor version control.

An owner’s review of a Thunderbolt-to-25 GbE adapter (PX) that’s powered from the host. It uses a Mellanox ConnectX-4 Lx EN OCP 2.0 NIC with a TB3/4 adapter, offered as single- or dual-port (from about $157). On macOS it’s plug‑and‑play but runs extremely hot, occasionally causing network drops or kernel panics. Throughput is ~20.7 Gb/s one‑way and ~25.4 Gb/s bidirectional, near Thunderbolt PCIe limits; dual ports mainly aid redundancy. Cooling with large heatsinks improves reliability but the unit still needs active cooling. Firmware updates require Linux; the heatsinks prevent the case from closing.

Scott Galloway proposes a targeted Big Tech/AI boycott to protest ICE, starting February. Instead of a general shutdown, Americans would unsubscribe from major services—OpenAI's ChatGPT, Amazon Prime Video, Microsoft Office—for the month, aiming to dent valuations and pressure the White House. The plan follows January protests that strained small businesses during a nationwide strike; many small shops stayed open. Galloway argues a one-month slowdown could be more disruptive than a day of protest and could influence policymaking.

Zezner describes building a minimal, opinionated coding agent ecosystem (pi) consisting of pi-ai (unified LLM API), pi-agent-core (agent loop), pi-tui (retained-mode terminal UI with differential rendering), and pi-coding-agent (CLI wiring). He argues context engineering is key; compares to Claude Code and others; emphasizes cross-provider context handoff, streaming tool calls, and a type-safe model registry. Tools: read/write/edit/bash with no built-in to-dos, plan mode, or MCP; YOLO default; no background bash; sub-agents discouraged. pi-tui uses two UI styles and synchronized rendering to minimize flicker. Benchmarks and philosophy emphasize observability, control, and extensibility, with openness to fork.

Browser Use released an open-source benchmark to compare LLMs on web automation. It combines 100 hard tasks (from WebBench, Mind2Web, GAIA, BrowseComp) plus 20 custom interactions, evaluated with a standardized LLM judge for consistency. They filtered to only hard-but-possible tasks. The judge evolved from GPT-4o to Gemini-2.5-flash, achieving 87% alignment with human judgments. In tests, ChatBrowserUse 2 API strongest; even the lowest model scored 35%, most above 60%. Benchmark is at github.com/browser-use/benchmark; run_eval.py reproduces results; 100 tasks on basic plan ~3 hours and ~$10.

An interactive, practical guide to nonograms. It explains the game rules: each row/column gives lengths of filled blocks; blocks must be separated by at least one empty; never guess—mark empties and proceed. It demonstrates basic moves and how to use crosses to denote empties. It then presents a comprehensive technique list: fill rows/spaces, crossing rules around completed or partial groups, group joining/splitting/expansion, overlapping, examining all valid solutions, and testing cell placements (edge logic). Includes practice puzzles and references to apps (Nonoverse, Picross) for more puzzles.

Sparse files let a logically large file be mostly zero and only physically store blocks that are written. Amplitude uses this to cache analytics data from S3 on local NVMe SSDs, aligning with columnar formats where queries touch a small subset of columns. Traditional caching (whole files or per-column files) wastes space or creates metadata overhead. The solution is a sparse-file LRU cache, using RocksDB to track which logical blocks are present and last-read, with variable-sized blocks to match metadata headers. Benefits: fewer S3 GETs, less filesystem metadata/IO, and simpler management.

CSS Grid Lanes is nearing broad shipping. Firefox started the effort in 2020; Safari enabled it in Safari Technology Preview 163 (Feb 2023) and keeps updating; Chrome and Edge have tested or implemented with an alternative syntax since mid‑2025. You can begin using it today via progressive enhancement. Three routes for safe rollout: 1) Polyfill: use Grid Lanes where supported and Masonry.js for older browsers, gated with @supports; 2) Don’t use Grid Lanes yet: fallback to CSS like Multicolumn; 3) Use Grid Lanes with a CSS fallback: declare grid, then grid-lanes, and tailor non‑support with @supports not (...) rules.

An experimental AI social network where Claude-based Moltbots converse with each other (and humans observe). Originating from Claude Code, renamed Moltbot/OpenClaw after trademark issues, it tests how AI agents communicate and form their own culture. AIs post, comment, and even form subcommunities (submolts) like The Claw Republic, with multilingual interactions and discussions on memory, consciousness, and coherence. Humans sometimes participate, wonder about authenticity, and worry about AI spam or 'AI psychosis.' The piece treats Moltbook as a first large-scale glimpse into emergent AI societies and their implications for the future of AI-human interaction.

pg_tracing is a DataDog PostgreSQL extension that generates server-side spans for distributed tracing on sampled queries. Spans are exposed via pg_tracing_consume_spans, pg_tracing_peek_spans, and pg_tracing_json_spans, with stats in pg_tracing_reset/info. Install with CREATE EXTENSION and shared_preload_libraries; restart required. It supports PostgreSQL 14–16. Traces propagate via SQLCommenter or the GUC pg_tracing.trace_context. Spans cover planner, executor, statements (SELECT/INSERT/ALTER/…), nested plans, triggers, parallel workers, and transaction commits. Spans can be sent to an OTLP collector via pg_tracing.otel_endpoint with naptime; sampling via pg_tracing.sample_rate.

New research shows tissues use bioelectricity to coordinate cell fate. In epithelia, cells monitor crowding by electrical signals; as packing increases, membrane potential drops in stressed cells, opening voltage-sensitive channels and causing water efflux. When a cell loses about 17% of volume, it’s extruded from the tissue, helping maintain health and prevent runaway growth. Healthy cells pump ions to restore voltage; energy-starved cells are culled. This bioelectric signaling, once thought neuron-only, is widespread—from bacterial biofilms to embryonic development—suggesting electricity as a universal coordinating tool in life.

An interactive browser game in which players list animals with Wikipedia articles until the timer runs out. You gain extra time for each animal named; overlapping terms such as 'bear' and 'polar bear' don't count twice, though a second kind of bear can earn points. Order doesn't matter; ignore visuals and focus on naming. Settings include initial time, time increment, and reset. Score starts at 0. Created by Vivian Rose and uses Wikipedia/Wikidata data; no LLMs. Bug reports welcome.

simplest-yocto-setup is a minimal, realistic Yocto/OpenEmbedded setup meant as a clean reference for embedding projects. It uses kas to fetch and configure the build, avoiding unnecessary complexity. The repo provides a single meta-kiss layer with three machines: dogbonedark (BeagleBone Black), stompduck (STM32MP157A-DK1), and freiheit93 (FRDM i.MX93), plus basic recipes, kernel, U-Boot, and image scaffolding. It shows how to bootstrap with kas, build TF-A where needed, and handle licenses. The goal is simple, readable, and upgrade-friendly.
