What platforms have something other than 8-bit char?
...
And now the final question. We have a buffer. The data from it is sent to TCP/IP network. Such network assumes 8-bit bytes. The question is: of what type the buffer should be? If your chars are 9-bit? If they are 16-bit? 24? Maybe each char corresponds to one 8-bit byte sent to network, and only 8 ...
What is the difference between a Docker image and a container?
... 'exec doc 4 months ago Up 12 weeks 0.0.0.0:5000->5000/tcp docker-registry
Here I'm running a dockerized version of the docker registry, so that I have a private place to store my images. Again, some things to note:
Like IMAGE ID, CONTAINER ID is the true identifier for the...
C++11 rvalues and move semantics confusion (return statement)
...ight, ETextureFormat fmt, string&& friendlyName)
{
std::unique_ptr<TextureObject> tex = D3DCreateTexture(width, height, fmt);
tex->friendlyName = std::move(friendlyName);
return tex;
}
It is a form of a 'leaky abstraction' but allows me to take advantage of the fact I ...
Why does base64 encoding require padding if the input length is not divisible by 3?

What are Padding Characters?
Padding characters help satisfy length requirements and carry no meaning.
Decimal Example of Padding:
Given the arbitrary requirement all strings be 8 characters ...
The new syntax “= default” in C++11
...lasses but you're be forced to anyway in C++03:
struct T {
std::shared_ptr<int> b;
T(); // the usual definitions
T(const T&);
T& operator=(const T& src) {
if (this != &src) // not actually needed for this simple example
b = src.b; // non-trivial operation

what is the difference between OLE DB and ODBC data sources?
...les the TDS protocol in managed code, only using native code to handle the TCP/Named Pipes/etc transmission over the network. For databases that don't have a managed provider of their own, you can use System.Data.OleDb to wrap OLE DB or System.Data.Odbc to wrap ODBC, but it's not recommended.

What are the differences between a multidimensional array and an array of arrays in C#?
...or the non-zero cases, the code pretty much resolves to (x*y_max+y)*sizeof(ptr)+sizeof(array_header). This calculation is about as fast (one multiply could be replaced by a shift, since that's the whole reason we choose bytes to be sized as powers of two bits) as anything else for random access to ...
Why aren't variable-length arrays part of the C++ standard?
... pointed out, C++ provides lots of heap-allocation mechanisms (std::unique_ptr<int[]> A = new int[n]; or std::vector<int> A(n); being the obvious ones) when you really want to convey the idea "I have no idea how much RAM I might need." And C++ provides a nifty exception-handling model fo...
Can a class member function template be virtual?
...e run-time type reflection and then creating a hash-map of (type, function-ptr) instead of vtable. It is doable. But very complex and very different to what we have now.
