Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Building a self-creating website with Supabase and AI
We'll loop the list of 80 IDs, picking a random piece of art from the original ID list. I'm using stdlib's random-sample which uses Fisher-Yates as its algorithm to randomize entries as I didn't want to bloat my own code too much with these kind of helpers. Fetching the artwork data I unfortunately noticed that some of the artwork do not have images available. This meant that we'll need to loop the list until we have 80 pieces with images. For the main piece of the story we keep things simple and just pick the first one in the list. We store some metadata along the way, too, which we can/will use later.

JSR: The JavaScript Registry
Unpkg serves whatever is published to NPM, and if it's a library intended for the browser, that often includes minified versions ready for use in script tags, for example, https://unpkg.com/[email protected]/mithril.min.js. Sometimes the default export is CJS (which has require() calls), in which case, you can usually use the browse url that I mentioned to see if there's another export you can use.
https://esm.sh/ is definitely a good option too if you're OK with modules.

Deno Cron
* Change my NPM imports to something that would work with Deno. The most straightforward thing to do was just change `import "foo"` to `import "npm:foo"`, but this felt hacky so eventually I used https://esm.sh, which worked for some packages but not others.
