    Hi HN! This is a hobby project of mine that recently landed me my first interview and helped me get my first internship offers. Draw on a QR code, and the health bars will accurately display how close the QR code is to being unscannable. How few errors does it take to break a QR code? How many errors can a QR code handle? Counters at the bottom track your record minimum and maximum damage. (Can you figure out how to break a QR code with 0.0% damage to the actual data region?) Also, click on the magnifying glass button to toggle between "draw mode" and "inspect mode". I encourage you to use…

    Stack Error is a pragmatic error handling library for Rust that provides helpful messages for debugging, and structured data for runtime error handling. Features: * Informative error messages: stack error messages and optionally add file/line context to your messages. This helps convey not just what went wrong, but also how it went wrong, making debugging faster. * Programmatic error handling: include optional error codes and URIs for robust runtime handling. * Library-Friendly: define custom error types easily while staying compatible with Rust’s error ecosystem. If designing good…

This book aims to provide hands on examples of implementing a number of concepts described in Google's SRE books. It also describes how i've seen SRE concepts impact some of the organizations I've worked in. A couple chapters are hands on debugging exercises going through the process of debugging applications based on data. I'm excited because every chapter describes something that I've done in paying…
