Why does struct alignment depend on whether a field type is primitive or user-defined?
...moving to nanosecond resolution. That means we can no longer use an 8-byte integer to represent the whole range of time we're interested in. That has prompted me to investigate the memory usage of the (many) structs of Noda Time, which has in turn led me to uncover a slight oddity in the CLR's align...
Sort NSArray of date strings or objects
...Date dateWithString: s2];
return [d1 compare: d2];
}];

What does “Memory allocated at compile time” really mean?
...ed inside the process memory map.
For example, consider a global array:
int array[100];
The compiler knows at compile-time the size of the array and the size of an int, so it knows the entire size of the array at compile-time. Also a global variable has static storage duration by default: it is...
