1, Basic introductionPolymorphism for the object-oriented thinking, the personal feeling is really important, he will be writing code in the elegant way also plays a very important role, in fact, many of the design patterns are used in most of the characteristics of polymorphic, Java in the polymorphic features used is very convenient, but C + + is very difficult to use, In fact, many states are: the definition of the type and the actual type, is gene
1. Four characteristics of a transaction: the most basic characteristic of a transaction, a well-designed database can guarantee the four characteristics.1.1 atomicity: Atomicity means that a transaction is an inseparable unit of work, and the operations in the transaction either occur or do not occur.1.2 Consistency: If the database is a state of integrity before the transaction is executed, the database r
The three main characteristics of object-oriented are encapsulation, inheritance and polymorphism.Encapsulation : The so-called encapsulation is to encapsulate objective things into abstract classes, a set of data and operations of these data functions encapsulated together to form a class, in declaring the class, we have some data and functions declared to be public, some data and functions are declared private, which are designated as common data or

DDoS attacks are essentially time-series data, and the data characteristics of t+1 moments are strongly correlated with T-moments, so it is necessary to use HMM or CRF for detection! --and a sentence of the word segmentation algorithm CRF no difference!Note: Traditional DDoS detection is directly based on the IP data sent traffic to identify, through the hardware firewall. Big data scenarios are done for slow DDoS attacks.Difficulty: In the attack, th

(2) There are two parameterized types with different type parameters and cannot be mixed. Public classGenericparametertest {//parameterized type T, which can be a reference type suc
Continuation of the articleIn the iOS7, a lot of new features are actually added. I've seen it before and I've learned some new things. such as the new dynamic characteristics, Textkit graphics and text mixed, as well as their own definition of animation jump and so on. That time is also more busy, no time to tidy up. Now that the project is finished, I intend to learn about the new content at the same time in learning the old things.First of all, the

I. Four basic characteristics of database transactionsA transaction is a series of operations performed as a logical unit, and a logical work cell must have four properties , called ACID(atomicity, consistency, isolation, and persistence) properties, in order to be a transaction. 1. atomicity (atomicity): The operations contained in a transaction are treated as a logical unit, and the operations in that logical unit either succeed or fail altogether.
