The interview in these days, I feel that the whole grasp of spring is still very weak. So we need to continue to strengthen.Here to explain the spring of these several aspects of the test, but the actual feeling is still wrong, this problem I think the need to really read the spring source code to say something to make sense. This kind of interview asks the law, also only is the interview the question law, to the actual grasp still has no slightest meaning. So I think there is a chance to read t
The so-called DB technology is the most commonly used to repair the map of the foreign countries ~ This method is the core of the Dodgeburn is basically derived from the previous calculation of the skin, but this will calculate the work of the constituency to the creator himself, not necessarily the curve to achieve dodge Burn requirements for color bands or mixed-mode changes whatever it is. This is a complete upgrade, especially with two black layer
The basic principle and process of fingerprint identification technology
Although fingerprint identification technology has entered the civil field, but its working principle is still relatively complex. Unlike manual processing, biometrics companies do not store fingerprint images directly. Over the years, the biometric companies and their research institutions have studied many fingerprint identificati

"On the side of a PBX or bureau switch, a small amount of electrical energy is not fully converted and returned along the original path to form an echo." If the caller is not far from the PBX or switch, the Echo returns quickly and the human ear cannot hear it, which is irrelevant. But when the echo returns more than 10ms, the human ear can hear the obvious echoes. In order to prevent echoes, the echo cancellation technique is generally needed, and special software code in the processor listens
It is said that China Netcom wants fiber optic access

In computer graphics, there are many ways to represent a real three-dimensional object, such as point cloud, mesh, voxel, curve, etc. this also affects the selection of the drawing primitives when drawing three-dimensional objects, the following is my summary of some of the classification of the drawing technology, I hope to be helpful to everyone.
research on real-sense graphics algorithm render three elements of a real image:
1. Precise Geometrical
Technology is the realization of design ideas, a design idea can have a variety of ways to achieve.
For example: How do we understand "lazy loading", there is a person ready to go to your house for a few days next month, you need to vacate the room this month. This month, when he doesn't exist, wait till he comes.
The design study is how to deal with the relationship between object and object (using)
design ideas originate from the problems enc
First, encryption technology
1. General Data encryption model
Note that there is a key on the A and B side.
2. Two Class cipher system
A) symmetric key cryptosystem and public key cryptosystem are divided according to whether the encryption key and decryption key are the same.
b) in a symmetric key cryptosystem, the encryption key at the end of a and the decryption key at the B end are the same. This kind of commonly used encryption algorithm has DE

B, h.265 Code codec
Optimized encoder Parameters--h.265 codec
This is the h.265 coding framework, which is the same as the mixed coding framework of H. For example, including inter-frame, intra-frame prediction, Entropy coding, deblocking in order to remove the "block effect", adding a new SAO filter to eliminate the ringing effect.
Comparison of parameters between C, H and h.265
As for the H. h.265 framework, although their proce
