I recently needed to automatically run JavaScript on a page (owned by someone else) that I wanted to refresh after regular intervals. Why would I want to do this? Well, I needed to watch a calendar for a cancellation so I can make a booking, and wanted to automate this process.
I am using GitHub Pages to host this blog, which was built with Gatsby. As you can probably see, I use a custom domain ([https://vanderbergh.com](https://vanderbergh.com)) which needs to be set in the GitHub Pages repository settings.
I recently had to resize several photos for my project page. Normally, I would use the excellent free image manipulation program GIMP. But I wondered whether there was an easier way to apply the same resizing to images without having to open GIMP.
Building something from scratch is a great learning opportunity. When I put together this blog, I could have done just that. And I could have opted to use a tutorial to guide me in this process.
