When need to generate QR code, most of us reach for a library and call it a day. Let’s dig dive and see exactly what is involved.

These hidden features and shortcuts will help you perform some of the most common Bash functions more efficiently.

Fixing memory leaks may not be not the shiniest skill on a CV, but when things go wrong on production, it’s better to be prepared! After reading this article, you’ll be able to monitor, understand, and debug the memory consumption of a Node.js application
