RSigma: The Sigma Toolkit That Actually Works

Stop guessing if your security rules work. RSigma is a complete toolkit that takes Sigma detection rules, checks them for errors, and actually tests them against real log data before you deploy them. It’s like a quality assurance team for your security alerts, all in one fast, open-source package. You get a linter to catch silly typos, an evaluator to see exactly why a rule fired or didn't, and a way to test your changes against old data to make sure you didn't break anything. It’s built in Rust, so it’s fast, and it plugs right into your editor for instant feedback.

Easyread: Read English Papers in Chinese

Easyread is the paper reader that turns dense English academic articles into comfortable, well formatted Chinese text. It solves the problem of trying to understand complex research by importing a PDF and letting a large language model translate the entire document page by page in the background. Unlike simple translation tools that break sentences, it preserves the original layout, keeping equations and tables exactly where they belong. The most interesting feature is the side by side comparison mode. As you scroll, the original English page flips automatically to match your current reading position. This lets you instantly check the source if a translation looks off.

Mesh2Motion: The Open Source Mixamo Alternative

Mesh2Motion is an open-source web tool that turns static 3D character models into animated characters by automatically attaching a skeleton and applying movement, solving the tedious problem of manually rigging characters in 3D software.
