> There are languages that make it very very hard to write bad code. Haskell [...] Sure, but how much slower is Haskell than an equivalent implementation in C? Some quick searching suggests numbers like 1000% slower... and no amount of security is worth a 1000% performance hit, let alone a vague "security mistakes are less likely this way" sort of security. Being secure is useless if your code is so slow that you have to run so many servers you don't make a profit. Could the Haskell compiler be improved to the point that this isn't a problem? Maybe. Ultimately I think the problem is that Haskell code is very unlike object code, and that makes writing a good compiler very difficult. C is essentially portable assembler; translating it to object code is much more trivial. > C is a language that doesn't offer many advantages but offers very many disadvantages for its weak assurances. C offers simplicity. Sure, there are some quirks that are complex, but by and large it is one of the simplest languages in existence. Once you understand the syntax, you've essentially learned the language. Contrast that to Java and C#: you are essentially forced by the language to use this gigantic and complicated library all the time. You are also forced to write your code in pre-determined ways, using classes and other OOP abstractions. In C, I don't have to do that: I can write my code in whatever way I feel makes it maximally readable and performant. C also offers flexibility: in C, I can make the computer do absolutely anything I want it to in exactly the way I want it to. Maybe I don't like 8-byte pointers on my 64-bit CPU, and I want to implement a linked list allocating nodes from a sparse memory-mapped pool with a known base address using 16-bit indexes which I add to the base to get the actual addresses when manipulating the list? That could be a big win depending on what you're doing, and (correct me if I'm wrong) there is no way to do that in Java or Haskell. > there's no longer many excuses to run around with raw pointers except for legacy code. If by "raw pointer" you mean haphazardly casting different things to (void * ) or (char * ) and doing arithmetic on them to access members of structures or something, I agree, 99.9% of the time you shouldn't do that. Or are you talking about that "auto_ptr" and so-called "smart pointer" stuff in C++? In that case, your definition of "raw pointer" is every pointer I've ever defined in all the C source code I've ever written. Pointers exist because that's the way computer hardware works: they will never go away. I'd rather deal with them directly, since it allows me to be clever sometimes and make things faster.
