Prosodical Thoughts: Mutation Testing in Prosody
This is a post about a new automated testing technique we have recently
adopted to help us during our daily development work on Prosody. It’s probably
most interesting to developers, but anyone technically-inclined should be able
to follow along!

If you’re unfamiliar with our project, it’s an open-source real-time messaging
server, built around the XMPP protocol. It’s used by many organizations and
self-hosting hobbyists, and also powers applications such as [Snikke … ⌘ Read more

Some IndieWeb protocols are complicated and there are sometimes no programming libraries to simplify the use of them, but ActivityPub is another beast. Although the standard is documented, the way the specific implementations (Mastodon etc.) work often isn’t and it’s hard to debug. So huge respect for the big rework. 👍 ⌘ Read more

Another change in my infrastructure setup: I replaced rathole with Chisel.

Erlang Solutions: Pair Programming
As a junior software developer, finding the right tools and techniques to help you learn a new language or technology can make a huge difference. While spending the last few months learning Erlang and Elixir, one of the techniques that I have found really helpful is pair programming.

I will be breaking down the concept of pair programming and my experiences with it so far, including the benefits and different ways of utilizing this programming style.

One year ago, I started using AdGuard Home instead of Pi-Hole to filter DNS requests and block ads and tracking. Yesterday, I switched to NextDNS instead.

AdGuard Home is awesome, but NextDNS seems to be working great as well and also integrates with Tailscale easily. ⌘ Read more
