This essay says that inheritance is harmful and if possible you should “ban inheritance completely”. You see these arguments a lot, as well as things like “prefer composition to inheritance”. A lot of these arguments argue that in practice inheritance has problems. But they don’t preclude inheritance working in another context, maybe with a better language syntax. And it doesn’t explain why inheritance became so popular in the first place. I want to explore what’s fundamentally challenging about inheritance and why we all use it anyway.

    “DI frameworks” are Satan’s farts. Classpath-scanning nonsense that turns compile-time errors into runtime errors. Not only is your Ctr still coupled to your Svc, but both are now coupled to Spring.

    Let’s qualify this: DI frameworks that use configuration files to specify the dependencies are Satan’s farts. You can use the DI pattern but do the injection in source code to get full compile-time type checking and all the benefits of a fully packaged JAR or similar binary. The root of the evil is having text files as part of the packaging, and not having the tooling to treat those files as part of the source code at build time.
