Coding Challenge #31 - QR Code Generator

This challenge is to build your own QR code generator.

This challenge is to build your own QR code generator.

A QR code (short for quick-response code) is a sort of two dimensional barcode. They were invented in 1994 by the Japanese company Denso Wave to label car parts. Like barcodes they are a machine readable optical image that can contain information.

Unfortunately this challenge is rather wordy, so it’s exceeded the length of a substack post! You can find the full challenge on the website as Build Your Own QR Code Generator.

News!

After several request for a self-paced, version of my cohort course I’m launching a a new course: Become a Better Software Developer by Building Your Own Redis Server (Python Edition)

The course will guide you through the Redis Coding Challenge using Python. You'll learn network programming, concurrency, test-driven development and how to build high-performance servers. At the end of it you will have built a fully working clone of the original Lua version of Redis in Python.

The course will be live on November 17th 2023. Until then it’s available at the pre-launch price of $100, after which it will be $150.

If Python isn’t your language of choice, it’ll be available in other languages in the coming months. You can help determine which comes next by voting in the poll below.

Other Ways I Can Help You:

1. I write another FREE newsletter Developing Skills that helps you level up the other skills you need to be a great software developer.

2. I am available for 121 coaching and mentoring.

3. I occasionally run a cohort based course: Coding Challenges Live: Redis Edition!
