A workshop that teaches you how to build your own coding agent. Similar to Roo code, Cline, Amp, Cursor, Windsurf or OpenCode.

This is a cleanroom deobfuscation of the official Claude Code npm package.

Groundhog's primary purpose is to teach people how Cursor and all these other coding agents work under the hood. If you understand how these coding assistants work from first principles, then you can drive these tools harder (or perhaps make your own!).

ACPI Table Extraction / SeaBIOS SLIC Integration.

GeoCoordinate is a portable class library (in v1.1.x) or netstandard v1.1 (from v2.x.x) compatible implementation of System.Device.Location.GeoCoordinate. It is an exact 1:1 API compliant implementation and will be supported until MSFT sees it fit to embed the type. Which at that point this implementation will cease development/support and you will be able to simply remove this package and everything will still work.

If you are just starting out on a new project I recommend using https://github.com/adamralph/liteguard instead of conditions. Especially if using in a mobile application, less allocations and better performance. This project is deprecated and needs a new maintainer. Contact me if you want to take over.

Apple doesn't provide any way to interact with their App Store programatically and Google doesn't provide a command line interface, which means releasing software can be a pain, releases don't happen as often as it should, and something frequently goes wrong because humans are involved. In this lecture, we find a solution to this very problem and other everyday tedious tasks, such as developer certificate provisioning and code signing by using the popular http://Fastlane.tools framework.

HttpClientDiagnostics is a cross platform, portable class library that provides tracing/logging telemetry to Microsoft.Net.HttpClient. In the spirit of "applications decide the logging framework, libraries should play nice" this package does not require any external dependencies or abstractions like Common.Logging

StatDNS allows you to perform DNS queries over HTTP, and to get reverse PTR records for both IPv4 and IPv6 addresses. It can be useful in client-side/mobile phone environments and server-side environments where you cannot perform DNS queries locally such as Microsoft Azure where UDP traffic isn't routed.
