Bart had an itch to scratch, and he decided to scratch it with PowerShell. You'll remember that he gave us a teaser Tidbit seven months ago in Tidbit 11, and we still haven't started learning PowerShell so this one is yet another teaser. The itch he had was trying to understand the "Monty Hall Problem" [en.wikipedia.org/...](https://en.wikipedia.org/wiki/Monty_Hall_problem), and by writing a script to simulate a thousand rounds of the game, he was able to finally understand the solution. It is great fun hearing Bart describe how he spent the first few days of his annual leave programming ... because it was fun!

We've been having great fun in Programming By Stealth learning how to use Jekyll to create a website using GitHub Pages. This week Bart goes through the challenge he left us with last time — to add a nav bar to our little static website using Bootstrap 5 along with Jekyll and Liquid templates. Bart had a lot of fun with his solution so it was fun to hear him dust off the cobwebs on Bootstrap.

Then we turn to learning about Jekyll's `includes` feature, which is reusable snippets similar to how TextExpander snippets let you write something and change it in only one place. The worked examples simplify the code in a way, and we learn how to use `includes` to create advanced image markup.

I also enjoyed learning about Liquid comments and how you can create white space between sections of your code for ease of writing and debugging that then never show up in the resultant HTML.

We continue our series on making websites using GitHub Pages. Building on our Jekyll knowledge with Liquid templates, we now learn how to create our own theme with Jekyll layouts. The terminology of Jekyll is still tricky, but with some worked examples and a challenge this time, maybe it will start to cement in our brains!
