When is it better to use String.Format vs string concatenation?
...out actually explaining why, which determined me to write this post :).
Idea is the .NET compiler is smart enough to convert this piece of code:
public static string Test(string s1, int i2, int i3, int i4,

...(as opposed to having each field stored in a corresponding column). Their idea was that "XML is the future", "disk space is cheap", and "processor is cheap", so there was no need to optimize anything. The result was that our 16-bytes packets were turned into 2kB documents stored in one column, and...

Copy constructor for a class with unique_ptr
...issing.
To avoid this, the copy has to be done via the clone-pattern. The idea is to do the copy through a virtual function clone_impl() which returns a Base* in the base class. In the derived class, however, it is extended via covariance to return a Derived*, and this pointer points to a newly cre...
