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...
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?
...ore sizeof, bytes and CHAR_BIT, and integer representation... let's burrow down the rabbit hole and see it for ourselves...
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...
CocoaPods - use specific pod version

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...
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...
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.
A Ha...
How can I see the request headers made by curl when sending a request to the server?
...t, it also prints the TLS handshake process when accessing website through HTTPS, such as curl -v https://www.example.com; second, it also prints the CONNECT request if you are visiting the site through HTTP proxy, such as curl --proxy my-proxy:8080 http://www.example.com. I believe it would help mo...
Do a “git export” (like “svn export”)?
... I tried : git archive --format=zip --output foo.zip --remote=https://github.com/xxx.git master And got fatal: Operation not supported by protocol. Unexpected end of command stream.
