White House: Future Software Should Be Memory Safe

White House: Future Software Should Be Memory Safe - Pawb.Social

On the one side I really like c and c++ because they’re fun and have great performance; they don’t feel like your fighting the language and let me feel sort of creative in the way I do things(compared with something like Rust or Swift). On the other hand, when weighing one’s feelings against the common good, I guess it’s not really a contest. Plus I suspect a lot of my annoyance with languages like rust stems from not being as familiar with the paradigm. What do you all think?

C++ can have excellent performance without ever using a single pointer and avoiding unsafe functions like gets() - this isn’t necessarily a judgment on language - it’s a judgement on bad programming habits.

Pointers fucking suck, in a modern C++ codebase everything should be pass by value or const/mutable ref. To my preference I’d rather drop mutable refs to force everything to be more functional but whatever.

A big difference between rust and C++ is that in C++ you say “everyone should passing by value or const ref (mutable ref if needed)”.

In rust, the default is passing by value. The default refs are consts, you have to explicitly make them mut, and the compiler will warn you if you don’t mutate a mut parameter.
