Ever wondered why Docker commands need sudo or docker group membership? The answer is baked into the Linux kernel itself. I wrote this post to peel back the curtain on what a container actually is. You’ll recreate container-style process isolation from scratch using standard command-line tools – building your own namespaces and cgroups by hand to see exactly what’s happening under the hood.

If you’ve ever adjusted an AI temperature slider without really knowing what it does, you’re not alone. These settings appear across AI tools and model APIs, but the actual mechanics rarely come with a clear explanation beyond “higher is more creative.” I wrote this post to change that. In it, I break down how Large Language Models select their next word, walk through the math behind softmax, and explain how temperature, Top-K, Top-P, and Min-P each shape the output – so you can tune these settings with confidence instead of guessing.
