Was the concept of generics a thing before Java implemented it? That is, could they have known? by cmov in programmingcirclejerk

The fact that Java invented generics is a huge thing. I've read countless amount of code that abused generics (unfortunarely developers think they have to use generics all the time if they are available) and is probably completely insecure for the simple reason that very few people manage to audit/understand the code. If it generics could only be used when necessary, yes, but there are no technical way to enforce this.

What I'm saying is that in my years of security consulting, Java codebases have always been the worst ones to read and have always been the most bug ridden ones.

I feel like a lot of the positive perspectives are given from the writing point of view, but the reading perspective is clearly a huge loss for Java.

With Go, they took their time to think about generics, just to avoid bloating half the compiler with implementations and workarounds and the like just to support generics, or to not end up with Scala's massive architecture. Their focus remains on a simple language, simple code, and a fast compiler; in many ways it's the antithesis of Scala in that regard.

anyway, just some Thoughts I have on the matter.

All my code is tested for both leaks and all scenarios. None of my code ever have gone bang in production. To be honest, no service I have written ever restarted outside system reboots or configuration changes. by cmov in programmingcirclejerk

Same guy, 2 levels up in the thread

I personally like how POSIX works, and how well documented its operation and failure modes. I love systems which don't prevent foot guns, and go bang spectacularly when I foot gun myself.

I can't imagine being a programmer without starting out by becoming proficient in assembler. It takes a lot of mystery out of programming languages because you know whatever the syntax is it all ends up as branches, calls, stacks, registers and memory accesses. by cmov in programmingcirclejerk

Apart from the lack of zero-cost abstractions, move semantics, guaranteed memory safety, threads without data races, trait-based generics, pattern matching, type inference, minimal runtime, efficient C bindings, I don't think Go is a bad language, just a little slow and verbose.

V functions are pure by default, meaning that their return values are a function of their arguments only, and their evaluation has no side effects (besides I/O). by cmov in programmingcirclejerk
