Why does sizeof(x++) not increment x?

What's the point of const pointers?
...
What does it matter where they point it, it is a pointer allocated on the stack? The function can't mess that up. It makes far more sense to use read-only pointers when dealing with pointer-to-pointers. It is not the same thing as int const! I'll downvote this just for that mislead...
Is there a concise way to iterate over a stream with indices in Java 8?

What is the difference between `-fpic` and `-fPIC` gcc parameters?
... below 2GB. Programs that require more than 2GB
of data must use "malloc" or "mmap" to allocate the data in the
heap instead of in the program's data segment.
When generating code for shared libraries, -fpic implies
-msmall-data and -fPIC implies -mlarge-data.

Create a list from two object lists with linq
...ed execution, using Concat would likely be faster because it avoids object allocation - Concat doesn't copy anything, it just creates links between the lists so when enumerating and you reach the end of one it transparently takes you to the start of the next! This is my point.
