Why aren't variable-length arrays part of the C++ standard?
...inding a good C++ish syntax for the things, and on discouraging the use of raw arrays in C++, whereas I focused more on the implications for metaprogramming and the typesystem. I don't know if he considers the metaprogramming/typesystem implications solved, solvable, or merely uninteresting.

What is the difference between “JPG” / “JPEG” / “PNG” / “BMP” / “GIF” / “TIFF” Image?
...are generally suited for photographs. It is not suited for illustrations, drawings and text, as compression artifacts from compressing the image will standout. Lossy compression, as its name implies, does not encode all the information of the file, so when it is recovered into an image, it will not ...
How do function pointers in C work?
...
@ajay It looks like he's writing raw hexidecimal values (for instance '\x00' is the same as '/0', they're both equal to 0) into a string, then casting the string into a C function pointer, then executing the C function pointer because he's the devil.

Why is C so fast, and why aren't other languages as fast or faster? [closed]
...g portions of higher-level language code close to the performance level of raw C. But, for most applications, your program spends most of its time waiting on people or hardware, so the difference really does not matter.
Enjoy.

The new keyword “auto”; When should it be used to declare a variable type? [duplicate]
...bjects being created, just by looking at the code.
1. Avoid using new and raw-pointers though.
Sometime, the type is so irrelevant that the knowledge of the type is not even needed, such as in expression template; in fact, practically it is impossible to write the type (correctly), in such case...

How do you convert a byte array to a hexadecimal string, and vice versa?
...u need to do these conversion, you tend to do them a lot. If someone needs raw speed, they just run the benchmarks with some appropriate test data in their desired computing environment. Then, tuck that method away into an extension method where you never look its implementation again (e.g., bytes.T...
Why does Python print unicode characters when the default encoding is ASCII?
...he same as case (4).
Conclusions:
- Python outputs non-unicode strings as raw data, without considering its default encoding. The terminal just happens to display them if its current encoding matches the data.
- Python outputs Unicode strings after encoding them using the scheme specified in sys.s...
Using std Namespace
...s are quite happy reading std::string, std::vector, etc. In fact, seeing a raw vector makes me wonder if this is the std::vector or a different user-defined vector.
I am always against using using namespace std;. It imports all sorts of names into the global namespace and can cause all sorts of non...
