   What memory errors and leaks? A good coder should be able to produce error-free code on first try, provided the documentation is clear and correct, and the problem is sufficiently simple (as in this case). Tests and debugging will only get

   Let me guess: it's still impossible to minimize a full screen game on Linux or alt-tab etc., and the joystick will still not be recognized if you plug it in after the game starts.

   So how did examining the hardware allow them to unlock any car? Ideally, shouldn't each car have its own secret key, and no amount of examination of one car or its ignition key would reveal the secret key of another one? The way I in

    But then you have to pull those iterators into almost everything that deals with your objects, making the code hard to follow, and wasting memory. The problem also gets worse when your objects are in more than one list (which you can't

    What is this? It claims to be a (GNU99) C library, but I don't see how this can be the case, considering all the non-C constructs in the sample code ($(), try/catch, foreach). So it this just a language of its own that is compiled

    Shell scripts are a terrible language for any kind of event handling. Consider that: - You're probably going to be starting a new process for handling each event. - You'll be using the filesystem to store state between events. -

    True, some language features can indeed make defensive code bit less verbose, but I believe their value is overestimated. My approach in C code is usually to assume no pointer argument is permitted to be null unless explicitly stated, and t

    All these attempts to eradicate nulls are getting ridiculous. The possibility of nulls is most often rooted in the essential complexity of a problem. If his function is intended to be called with a possibly incorrect personId, the null chec

    If you feel a need to do that, check cmccabe's comment on the top about intrusive data structures. These let you do your own memory management, in a way that the data structure implementation doesn't need to know about.

    Intrusive data structures are indeed more powerful. I made my own instrusive AVL-tree which can be found here [1] and an example here [2]. There's also the extra feature that the concept of a "link" is abstracted, so you can

    I'm completely in favor of this. Garbage collection has no place in the core definition of any language that targets OS kernels and other high-performance applications. It's sad how we have so many languages that fix many of C++'s problems

    by ambrop7 13y ago

    The language doesn't define "correct const usage" the way you see it. It only specifies what is defined and undefined behavior. Casting a pointer-to-const to a pointer-to-non-const and modifying an object via that is defined behavior as lon

    I've actually just looked at the standard and there is a clear example something like this: int x; int const *cpx = &x; int *px = const_cast<int *>(cpx); *px = 1; // defined behavior, modifying non-const object through

    I think the reasoning is wrong here. Obviously a tower could be stable, but still applying force to an edge of the top could make it collapse. What's actually happening is that at each step, you already have a max-overhang tower of N bricks

    You might like a programming language I make, "NCD". See: https://code.google.com/p/badvpn/wiki/NCD It follows a similar philosophy to Nix but for runtime management of processes and events in general. It's really functional though. But i
