These are some of the hobby projects I’ve been working on in my spare time. Most of them revolve around mountaineering, climbing, and building tools to scratch my own itches.

dreamiurg/claude-mountaineering-skills - A Claude Code plugin that automates research on North American mountain peaks by aggregating data from specialized mountaineering websites. It compiles peak information, weather forecasts, trip reports, and hazard data into comprehensive route beta reports for trip planning.

dreamiurg/peakbagger-cli - A command-line tool for accessing mountain peak data from PeakBagger.com. It enables searching peaks by name, retrieving detailed elevation and prominence information, analyzing climbing statistics with seasonal patterns, and accessing trip reports with beautiful terminal formatting or JSON output.

dreamiurg/mountaineers-assistant - A Chrome extension that enhances the Mountaineers.org climbing platform by syncing activity history locally and providing interactive dashboards. It displays personalized climbing statistics and visualizations filtered by activity type and partners, all without storing data on external servers.

dreamiurg/gpxbridge - A command-line tool that retrieves GPS activities from Strava and exports them as GPX files for archival or import into other mapping services like GaiaGPS or CalTopo. It provides automated OAuth authentication with Strava’s API and offers filtering options including activity type and date ranges.

dreamiurg/bitcount - A benchmarking tool that measures the performance of different bit counting algorithms on various hardware architectures. It implements 14 distinct approaches ranging from simple iteration to CPU-optimized techniques like POPCNT and SIMD, allowing developers to compare execution speeds across methods.

dreamiurg/django-fab-templates - Django starter templates that integrate automated deployment capabilities using Fabric. The templates support multiple hosting environments including Vagrant and WebFaction, offering pre-configured features like database migrations, HTML5 boilerplate structure, and environment-specific configurations.

dreamiurg/avr-liberty - A library of easy-to-use C functions for working with AVR microcontrollers. Built as an open-source successor to the outdated Procyon AVRlib, it provides pre-built support functions to help developers work efficiently with AVR processors and modern compiler versions.
