 I blogged about [hosting a reading list on this blog](https://lewisdale.dev/post/managing-my-reading-list/) a little while ago. At the time, I decided that storing the books as JSON would make sense - and it did, at the time. But as the list has grown, albeit not exponentially, it started to get a bit messy.

 Open Graph images are what websites such as Twitter choose to display when showing a preview to a page. There are plenty of ways to generate these dynamically - like using Netlify Edge Functions, for one.

 Given the drive to move all of my content into one place and syndicate it to other networks, I decided that I'd also try out doing microblog-style posts with Eleventy. Before I could do that, I needed to add a CMS (there's no way I'm manually adding Markdown files everytime I want to post a status).

 I've decided to put a bit more love into this blog, I've neglected it since the new year. As part of that, I wanted to make a few more changes - namely, I wanted some better navigation to allow me to write different types of content. So, I've added a little category list to the site to allow people to search by different tags.

 A little while ago I was toying with building a lightweight web app that would make it easy to manage and share reading lists. I never got around to making it, but instead I built a very-MVP version by adding my [reading list](/reading-list) to this website. It was a fairly simple construction, I simply added a file called `reading-list.11tydata.json` to my source directory, that looked like this:

 One of the things I struggle with the most is note-taking: I can't do it during meetings because then I'm distracted by the writing and not, you know, participating. So I end up not doing it at all, and then I have absolutely no record of what was said and often forget things.

 I have two servers: a VPS, and a small server that I primarily use on my home network. The server at home is quite a bit more powerful than my VPS, and significantly cheaper to run, so I'd like to start moving some of my hosted services to it. The problem is that I don't have a static IP, so I'd need to get dynamic DNS setup and open the right ports on my router, which is a bit tedious (and not officially supported by my ISP).
