A house back in 2017. I really had no business buying a house, financially speaking, but I was getting fed up with renting land under a trailer I owned. They kept raising the price significantly every single year. Turned out to be a great decision since I was able to get a good interest rate and a good price. Of course there are downsides, like when the water heater flooded my bottom floor. Still worth it though.

I used to think C# was like Java but with fresh ideas. I still do, but Kotlin gives it a run for its money. The type system is pretty great. For example, you can use the Elvis operator to return early if something is null, allowing you to use a non-null type afterwards. In C#, nullable annotations feel more “grafted on”, and there are some weird quirks and footguns that Kotlin avoids by being a little smarter about it.
