I've decided to take some time off of work recently, and thought it would be fun to put a spin on "how to" blog posts. In addition to writing about a particular topic, I thought it could be cool to actually deploy it somewhere and allow it to be publicly used. I've had this idea before, but I'd still like to have user authentication that I can streamline across various applications at different subdomains. There are plenty of auth solutions out there, but I recently came across one that is simple to deploy called [Pocket ID](https://pocket-id.org), which exclusively uses [passkeys](https://www.passkeys.io).

If you're interested in a sort of running Curriculum Vitae, then read on to learn a little more about me, as well as my current and past misadventures! If you're looking for something more official looking, you can get the most recent copy of hand-crafted LaTeX resume [here](/resume/mark-rudolph-resume.pdf).

Hello, class. Today we're going to use sbt to publish artifacts to GitHub packages via GitHub Actions when we tag/release our codebase, and we're not going to use *any* sbt plugins to do it!

I've been using ZIO at work for about a year now, and thought I would share some of my learnings. On a couple of occasions, I've helped bring people up to speed on using ZIO in our code bases, so this could be thought of as a getting-started highlight for Scala developers who are familiar with the language, but not necessarily functional effect-based system - in this case, ZIO.
