As a Java engineer in the web development industry for several years now, having heard multiple times that X is good because of SOLID principles or Y is bad because it breaks SOLID principles, and having to memorize the “good” ways to do everything before an interview etc, I find it harder and harder to do when I really start to dive into the real reason I’m doing something in a particular way.
One example is creating an interface for every goddamn class I make because of “loose coupling” when in reality none of these classes are ever going to have an alternative implementation.
Also the more I get into languages like Rust, the more these doubts are increasing and leading me to believe that most of it is just dogma that has gone far beyond its initial motivations and goals and is now just a mindless OOP circlejerk.
There are definitely occasions when these principles do make sense, especially in an OOP environment, and they can also make some design patterns really satisfying and easy.
What are your opinions on this?
Emulation code where you expect unsigned integers to wrap around instead of being UB is a good example, because it was guaranteed for programmers working on the emulated systems.
That’s just how it works and have always worked. You can use an unsigned char on a 64 bit system and it’ll behave like on the Commodore 64. I don’t understand what you are trying to show.
When a system uses words of a specific size, you need to use the same size for wraparound behaviour to work as expected. Incrementing 0xffff by one needs to return 0. It’s easy if you use a uint16_t. Not so much if you use an unsigned of unspecified length.
We are in a total agreement here.
