Cal's notes

Small experiments worth writing down.

Really Simple is where I keep the useful bits from my own tinkering: phone-shaped Linux setups, command-line workflows, AI tools, and the occasional lesson from trying to make a project real.

About

I am Cal. I like FOSS, weird hardware, retro things and well designed systems. These posts are notes from that work, cleaned up just enough to be useful later.

Shell-GPT: Your Interactive AI Assistant in the Linux Shell

Shell-GPT is a practical tool for enhancing user control through a command-line interface using LLMs to simplify everyday tasks.

Embracing Blogging: Lessons from Simon Willison

I have always wanted to start blogging but never saw myself as an author and felt I did not have the time to dedicate to it. However, my perspective began to change when I came across Simon Willison on Mastodon. I started following him because of his awesome LLM tool, which piqued my interest.
