Publish and subscribe (pub/sub) is a powerful pattern that every developer should know. And while cloud hosting is awesome, sometimes it’s nice to take a little finer-grained control over the software that’s hosting your application. While working on moggers.gg, the time finally came to add notifications to the stack. Since the back-end is nginx fronting […]

Sadly, PowerPoint doesn’t have a generic field replacement function like Word does. So, either I type some stuff and have to remember […]

All of this switching back-and-forth can be tedious, so I wrote […]
