I used to obsess over how many queries per second a server could handle, whether a list was using more memory than an array. Which RNG was more random, whether CSS tables were better than flex. All of those are details to worry about later. Jeez! It's funny how reading so many HN tech blogs actually limited me, I was trying too hard to be a perfect programmer.

Actually I got turned on to single-file Java by HackerRank (where that's the only way you can write Java) so it was about getting better at coding, not getting worse. It's fun because you have to know a few details about the language that aren't widely known (you can define as many classes as you want in a file, only one of them can be public.) It is handy when you want to write things that are really scripty or self-contained like you might want to do for tests. I'm not one of them but there are many people who hate Java and hate object-orientation and single-file Java provides many chances to fight orthodoxy. Sometimes people are very happy to see single-file Java but sometimes it really drives people up the wall... If you want to break all the rules for your tribe it's a great foundation to start with.
