   I recently took a deep dive into the Linux kernel to understand how it handles processes, scheduling, memory, and more. While I had some OS knowledge from school, it always felt too abstract - so I wanted to see how things actually work. Th

   After more than a decade of writing software, I've read lots of opinions on how to write good software. Everyone loves to throw around rules and principles, so I'll do it too.

    I've been working with Terraform for a while now, and I've noticed that there are a few things that people keep asking me about. I thought it would be helpful to write a blog post about some of the most common questions I get aske
