Why is volatile not considered useful in multithreaded C or C++ programming?
...n
properly-written kernel code, volatile can only serve to slow things
down.
Consider a typical block of kernel code:
spin_lock(&the_lock);
do_something_on(&shared_data);
do_something_else_with(&shared_data);
spin_unlock(&the_lock);
If all the code follows the locking...
How does the main() method work in C?
...s are executed: setup stack, registers, MMU, memory mapping etc. Then copy-down of init values from NVM to static storage variables occur (.data segment), as well as "zero-out" on all static storage variables that should be set to zero (.bss segment). In C++, constructors of objects with static stor...
In HTML5, is the localStorage object isolated per page/domain?
... storage. (Caveat: If you access them from different protocols, EG http vs https, those are not shared. Within the same protocol, subdomain, domain, and port -- they are shared. This is a simplification of the concept of 'Origin'.)

What is Normalisation (or Normalization)?
... should be mentioned that normalization is a bottom up approach, not a top down approach. If you follow certain methodologies in your analysis of the data, and in your intial design, you can be guaranteed that the design will conform to 3NF at the very least. In many cases, the design will be ful...
Is the size of C “int” 2 bytes or 4 bytes?

sizeof, bytes and CHAR_BIT
The following statement, taken from the C standard (linked to above), describes this in words that I don't think can be improved upon.
The si...

Correct format specifier to print pointer or address?
...he start of 0xA1B2CDEF appears thus, not like 0xa1b2cdef which dips up and down along the number too. Your choice though, within very broad limits. The (uintptr_t) cast is unambiguously recommended by GCC when it can read the format string at compile time. I think it is correct to request the cas...
HashSet vs. List performance
...
Whether to use a HashSet<> or List<> comes down to how you need to access your collection. If you need to guarantee the order of items, use a List. If you don't, use a HashSet. Let Microsoft worry about the implementation of their hashing algorithms and objects.

How can I get the full/absolute URL (e.g. https://example.com/some/path ) in Django without the Sites module ? That's just silly... I shouldn't need to query my DB to snag the URL!
