I Launched a Severance Pay Calculator
I recently launched a small tool: SeveranceGO-CN: China Severance Pay Calculator . The source code is also on GitHub: masonblog/SeveranceGO-CN . Its purpose is straightforward. After you enter information such as the start and end dates of employment, last year’s income, the place where the employment contract was performed, whether a written contract was signed, and the reason for departure, the tool estimates statutory severance, damages for unlawful termination, payment in lieu of notice, and the possible double-wage range for failure to sign a written employment contract. ...
With AI, I Built a Provincial Leave Policy Lookup Site

Claude Code Source Leak: The Chain Reaction Caused by One .npmignore Mistake
On March 31, 2026, the AI world received an unexpected “April Fools’ Eve gift”: the full source code of Anthropic’s star product, Claude Code, accidentally made its way onto the internet because of a packaging mistake. This was not a hack. It was not an insider leak. Someone simply forgot to add *.map to .npmignore. Just like that, 510,000 lines of TypeScript, 44 hidden feature flags, and a mysterious background autonomous agent called KAIROS were exposed to everyone within hours. ...
How to Use ClawdBot on Windows: Build a Personal AI Assistant with Gemini and Telegram
Have you heard of ClawdBot? It is a very popular open-source personal AI assistant. Unlike traditional chatbots that simply wait for instructions, ClawdBot has a degree of initiative: it can message you proactively, manage tasks, and run on your own local device. Many tutorials recommend running it on a Mac Mini or a Linux server, but running it on Windows is perfectly fine too. In this post, I will walk you through installing ClawdBot on Windows, configuring it to use Google’s Gemini API (currently one of the best AI model options, with a free quota), and connecting it to Telegram, so you can chat with your AI assistant anywhere. ...
