Why should I use a pointer rather than the object itself?
...s the storage duration of the object. When doing Object myObject; within a block, the object is created with automatic storage duration, which means it will be destroyed automatically when it goes out of scope. When you do new Object(), the object has dynamic storage duration, which means it stays a...

What is referential transparency?
...ct to the context in which they appear in. Context dependence of any kind blocks referential transparency in some way or the other. If you try to understand the meaning of terms without regard to the contexts they depend on, you would again end up with confusion. Quine was concerned with the mean...
Cartesian product of x and y array points into single array of 2D points
...lt_type.
Notable alternatives
It's sometimes faster to write contiguous blocks of memory in Fortran order. That's the basis of this alternative, cartesian_product_transpose, which has proven faster on some hardware than cartesian_product (see below). However, Paul Panzer's answer, which uses the ...
Difference between GIT and CVS
... access via custom efficient git://protocol, or if you are behind firewall blocking DEFAULT_GIT_PORT (9418) you can use plain HTTP.
For CVS most common solution (as I understand it) for read-only access is guest account for 'pserver' protocol on CVS_AUTH_PORT (2401), usually called "anonymous" and ...

Why does struct alignment depend on whether a field type is primitive or user-defined?
...ff heap (VirtualAllocEx for e.g)
this way you are given you own memory block and you manage it the way you want.
The final question here is why all of a sudden we might get layout like that. Well if you compare the jited code and performance of a int[] incrementation with struct[] with a counte...
