  • Configuring React SPAs at Runtime

    Configuring a SPA is a tricky affair. I found some tools to make it a little bit easier, but it should still be used with a fair amount of caution. The App I built a small React UI to view some additional information that I am storing in my Unifi Controller for network devices. Using…

  • Talk to Me Goose

    I’ve gone and done it: I signed up for a trial of Github Copilot. Why? I had two driving needs. In my work as an architect, I do not really write a TON of code. When I do, it is typically for proof of concepts or models for others to follow. With that in mind,…
