Краткая памятка по битовым операциям
Setting a bit Use the bitwise OR operator (|) to set a bit. number |= 1 << x; That will set bit x. Clearing a bit Use the bitwise AND operator (&) to clear a bit. number &= ~(1 << x); That will clear bit x. You must invert the bit string with the bitwise NOT operator (~), then AND it. Toggling a bit The XOR operator (^) can be used to toggle a bit. number ^= 1 << x; That will toggle bit x. Checking a bit You didn't ask for this but I might as well add it. To check a bit, AND it with the bit you want to...

Singletons in C#
The singleton pattern is one of the best-known patterns in software engineering. Essentially, a singleton is a class which only allows a single instance of itself to be created, and usually gives simple access to that instance. Most commonly, singletons don't allow any parameters to be specified when creating the instance - as otherwise a second request for an instance but with a different parameter could be problematic! (If the same instance should be accessed for all requests with the same parameter, the factory pattern is more appropriate.)...

Признаки равенства, сравнения и их отличия
IEquatable:This interface is implemented by types whose values can be equated (for example, the numeric and string classes). A value type or class implements the Equals method to create a type-specific method suitable for determining equality of instances.The IComparable<T> interface defines the CompareTo method, which determines the sort order of instances of the implementing type. The IEquatable<T> interface defines the Equals method, which determines the equality of instances of the implementing type.bool Equals(T other)IComparable:This...

Assigning pointer to pointer in Objective-C
Pointer variable is a variable itself, so it has an address. So &str1 results in the address of the pointer variable, and str1 is an expression that results in whatever the pointer variable is holding - the address of the object it's pointing to. Assume that: the object holding the NSString "one" is at address 0x00000100the object holding the NSString "two" is at address 0x00000200 Then your pointers might look something like this: At initialization: str10xbfffd3c8 +---------------+ | | | 0x00000100 ...

How to Create, Load, and Use Multiple Nib Files
In Mac OS X, application management is a single drag & drop operation: drop the application into /Applications to install, and drop it into the Trash to uninstall. This simplicity and power is just the tip of the iceberg. What we're seeing is just one use of a more general facility Cocoa calls bundles. This article is about Nib files, and how to use them in your applications. Nib files are just specialized bundles, so we'll talk about bundles first. // Bundles A bundle is a directory containing code and resources. Applications,...
