rod-cli: Chrome Automation from the Command Line
— Leveraging the rod browser automation library, rod-cli provides a lightweight Go-based command-line tool for scripting persistent headless Chrome sessions. Each CLI command connects to and manipulates the same long-running Chrome instance via DevTools Protocol, enabling seamless multi-step browser automation in shell scripts or interactive use.

Rod: Go Library for Chrome Automation -- Comprehensive API Reference
— Rod is an advanced Go library designed to automate Chrome browsers using the Chrome DevTools Protocol, providing a comprehensive API for web scraping, browser control, element interaction, and robust waiting strategies. With high-level convenience methods (such as Must-prefixed methods for fast scripting) and direct protocol access, Rod enables streamlined workflows from simple scraping to complex automation scenarios, all without third-party drivers.

datasette-sqlite-history-json 0.1a0
— Track changes to data using triggers and hidden JSON tables
Research
krunsh
— Krunsh is a minimal Go CLI tool that executes newline-delimited shell commands inside an ephemeral KVM-based microVM, leveraging the libkrun library for lightweight virtualization. By piping commands from stdin, krunsh spins up a microVM, runs the specified commands using `/bin/sh -c`, captures the output, and discards the VM afterward, ensuring zero persistent state and strong process isolation.

Monty WASM + Pyodide
— Monty WASM + Pyodide explores compiling Monty—a Rust-based, sandboxed Python interpreter—into WebAssembly for seamless browser access. It provides two integration paths: a standalone WASM module accessible directly from JavaScript, and a Pyodide-compatible wheel for usage in Python-in-the-browser environments. The project enables safe, dependency-free Python code execution with features like variable injection, output capturing (including print statements), and robust error handling.

Building PyO3/Maturin Rust Extension Modules as WebAssembly Wheels for Pyodide
— Compiling Rust-based Python extension modules (via PyO3 and maturin) into WebAssembly wheels for Pyodide involves precise coordination of toolchain versions and build flags to ensure compatibility. The process relies on maturin (≥1.0) for packaging, the Emscripten SDK (with the exact version used by Pyodide), and a Rust nightly toolchain matching Pyodide's ABI, particularly the `-Z emscripten-wasm-eh` flag and a compatible sysroot for Python 3.13 (Pyodide 0.28+).

just-bash: Deno JSONL Server + Python Client
— Exploring the capabilities of just-bash, this project integrates the TypeScript-based bash emulator into a persistent, JSONL-over-stdio server in Deno, accessible via a robust Python client library. The solution enables sandboxed bash scripting with comprehensive built-in commands, a virtual filesystem, and optional network access, with persistent state and fine-grained request control (env, cwd, timeout) supported.
Research
WASM REPL CLI Tools
— WASM REPL CLI Tools enable JavaScript and Python REPLs from the command line by leveraging WebAssembly runtimes in Go, built on the wazero engine. The project supplies separate binaries for each language—one using QuickJS WASI and the other CPython WASI—offering direct code execution, interactive shells, and a JSONL mode. JSONL mode lets external applications submit code for execution while maintaining persistent state across requests, facilitating programmatic integration.

Running OpenClaw in Docker
— I'm not brave enough to run [OpenClaw](https://openclaw.ai/) (aka Clawdbot aka Moltbot) directly on my Mac, so I decided to try running it in a Docker instead container.
Tool
SQLite AST
— Parse SQLite SELECT queries into abstract syntax trees and view the results in JSON and Python representations. This tool uses the sqlite-ast library running in your browser via Pyodide to analyze SQL syntax and display both the dictionary-based parse tree and a rich pretty-printed representation. It supports complex queries including compound selects, common table expressions, and window functions, and can display partial parse results when encountering syntax errors.
