At work I needed to create a fixed Java work pool. By “fixed”, I mean a pool that has no queue: it has a maximum number of workers, and it should not store work if it has no capacity to immediately process.

Content Management Systems for Static Sites

Static Site Generators I’m a huge fan and proponent of static site generators. They give me the flexibility to easily work offline (the Internet can be spotty out where I live), have everything backed up in Git, and the ability to deploy anywhere. My brother and his wife are thinking of creating a blog. As much as I love the way I blog (terminal + Neovim + Git), it doesn’t lend itself to people who don’t understand git and markdown.
