Redis JavaScript Module
— Expanding Redis’s scripting capabilities, the Redis JavaScript Module enables users to execute JavaScript scripts in Redis through the fast, embedded mquickjs engine, paralleling the Lua scripting features but with a JavaScript syntax. This module introduces commands like `JS.EVAL`, `JS.LOAD`, and `JS.CALL`, supporting script execution, caching, and invocation by SHA1 hash, along with native integrations for running Redis commands, logging, and error handling within scripts.

Debug: Failed Cog Code Fix
— Debugging investigation into why commit 0dcfad4's fix for cog code rendering didn't work. The fix correctly used string concatenation to avoid `-->` in Python strings, but the explanatory comment itself contained the literal `-->` sequence, which closed the HTML comment early. Solution: rewrote the comment to avoid the problematic character sequence.
Research
Vibium Python Client Investigation
— Examining the Vibium browser automation project, this investigation developed a Python client library that interoperates with Vibium’s Go-powered "clicker" binary and existing Node.js tools. The Python client exposes both synchronous and asynchronous APIs, replicating advanced browser automation features such as auto-waiting, visibility checks, and custom commands (e.g., `vibium:find`, `vibium:click`) via WebDriver BiDi over WebSocket.
Tool
PG&E Outage Map - Half Moon Bay Area
— Track power outages affecting the Half Moon Bay area with this interactive map displaying real-time PG&E outage data within a 15-mile radius. The application visualizes outage locations as point markers and affected areas as polygons, while displaying key statistics including the number of outages, impacted customers, and affected regions. Custom markers can be added by providing a URL parameter, and the map automatically refreshes every five minutes to ensure current outage information.
A new way to extract detailed transcripts from Claude Code
I’ve released claude-code-transcripts, a new Python CLI tool for converting Claude Code transcripts to detailed HTML pages that provide a better interface for understanding what Claude Code has done than even Claude Code itself. The resulting transcripts are also designed to be shared, using any static HTML hosting or even via GitHub Gists.
