Is gcc's __attribute__((packed)) / #pragma pack unsafe?
...r to write programs which access the contents.
Otherwise you end up using C++ and writing a class with accessor methods and stuff that does pointer arithmetic behind the scenes. In short, packed structs are for dealing efficiently with packed data, and packed data may be what your program is given ...
What is the performance of Objects/Arrays in JavaScript? (specifically for Google V8)
...rlying array data. In V8 specifically, these are essentially the same as a C++ array so those rules will apply. If for some reason you're working with an array that the engine isn't able to determine with confidence is an array, then you're on much shakier ground. With recent versions of V8 there's ...
What are the differences between Autotools, Cmake and Scons?
...n in this day and age. Unless you're building something like glibc, libstdc++, or GCC on a truly ancient version of Solaris, AIX, or the like, the tests are a waste of time and are a source for many, many potential breakages of things like mentioned above.
It is pretty much a painful experience to ...
What are the mathematical/computational principles behind this game?
...ng about. it uses exactly 57 pictures, and sorry guy's I've written actual C++ code but knowing that vector <something> is an array containing values of type something it's easy to understand what this code does. and this code generates P^2+P+1 cards using P^2+P+1 pictures each containing P+1 ...

@WernerCD I'd say the fact that C and C++ has a keyword for suggesting that which (A) is ignored by many modern compilers and (B) it was decided not to put in C#, suggests that this isn't something we'll see in any more direct way.

Benefits of header-only libraries
...ery project then this doesn't really apply.
Basically if you compile your C++ code and build a library with one compiler then the user tries to use that library with a different compiler or a different version of the same compiler then you may get linker errors or strange runtime behaviour due to b...
Java naming convention for static final variables [duplicate]
...rgument is something that has been somewhat blindly adopted from the C and C++ languages. In my estimation, that is not justification to continue the tradition in Java.
Question of Intention
We should ask ourselves what is the function of static final in our own context. Here are three examples of...
Difference between Covariance & Contra-variance
... the crux. C# does not support covariant return types, but Java as well as C++ do. I rather described the theoretical ideal by using a C#-like syntax. In C# you need to let Bird and Duck implement a common interface, in which Lay is defined to have a covariant return (i.e. the out-specification) typ...
