Company A = Company B
Company A owns more than 50% of company B
Company A Controls K (k >= 1) Companies denoted

1. If the user enters the MJ string in the text boxThen it can be said that the text property of the Namefield is a pointer to the NSString object, which is the owner, which holds the contents of the Text input box2. If the following code is executed

An object can have multiple own
are Engine, host, and context components, respectively. These 3 components represent different service scopes, and by nesting relationships you know that the scope of 3 components has the following relationship: Engine>host>context. The A.engine component can contain multiple host components that process all customer requests for a specific service component. B. A host component represents a virtual host, and a virtual host can contain multiple Web applications (context components). The C.conte

The amount of money a person has is not the ownership of the money he owns, but the right to use the money he owns. How much ability a person can do, not just what he can do when he is alone, but also what he can do through others. 12.5% of the money a person makes depends on his own knowledge, and 87.5% of the money is
Today, a colleague asked me why I used assign to declare attributes in objective-C delegate. I checked the information on the Internet and summarized it as a memory management problem in objective-C. I copied the foreigner's answer directly:
The reason that you avoid retaining delegates is that you need to avoid a retain loop:
A creates B a sets itself as B's delegate... A is released by its owner
If B had retained a, a wouldn't be released, as B owns

SET-GID and SET-UID are to make the app executor have the same group and user ID as the app owner, such as ping the app, whose owner is root because ping uses the reserved port, common users are not allowed. For everyone to use ping, set the ping set-uid bit so that the ping user can have the root permission in the ping application.

money, it will take shares in the company. I think there are three key proportions. (1) If the investor holds more than 66.7% of the shares, then he has absolute control, because the company generally stipulates in the Articles of Association that the company's major decision should pass more than 2/3 of the shares. (2) If the investor owns more than 50% of the shares, then the investor also has the right to make decisions on general issues, but on m
thing is legal.The most important of these algorithms is that their security depends on key, which generally depends on the length of the key. In other words, it is very difficult to solve the problem of knowing the algorithm without knowing the key. In fact, the commonly used key-based encryption algorithm can be found on the network.Key-based encryption algorithms also include two classes: symmetric and asymmetric encryption.Symmetric encryption refers to the use of identical keys on both sid

Java multithreading (synchronization and deadlock, producer and consumer issues)
First, let's look at the synchronization and deadlock issues:
A deadlock means that A owns banana and B owns apple.
A said to B: If you give me apple, I will give you banana.
B said to a: If you give me banana, I will give you apple.
However, both A and B are waiting for the reply from the other party, so the final result is
Configuring Beans Through Factory methodsTo create a bean by calling the static factory methodCreating a bean through a static factory method encapsulates the process of creating an object into a static method. When a client needs an object, it simply calls the static method without caring about the details of the object being created.To declare a bean created through a static method, you need to specify the class of the method that owns the factory i
