The raft protocol is easier to understand and easier to implement than the Paxos advantage. It strengthens the position of leader, divides the whole protocol into two parts clearly, and makes some simplification by using the continuity of the log: (1) leader. By leader to the follower synchronization log (2) leader hung up, select a new leader,leader election algorithm.
But in essence, it is easy to place the process clear, the description is clearer, the key is to give a description of the pseu
DICOM is a standard that medical imaging technicians cannot escape. This series of topics focuses on the DICOM standard, which is intended to be understood by PACS administrators and software engineers.
Member of the ISO organization. As a standardAccuracy and universality of expressions, Wording is very cautious. This has a secondary effect: something that was originally quite clear. After using its noun system, it became very vague.

Daydream keyboard is coming
VR has become a hot topic in the consumer industry, while the input experience of VR is different. On the physical layer, each manufacturer provides a different handle design, but if you want to solve the input, it is clear that the handle will be limited. In this case, a virtual keyboard is needed. Google took the lead in launching the Daydream keyboard application because of u

Problem DescriptionIt is said that in a long long time ago, poor rabbit experienced the biggest blow in life-the race lost to the turtle, heart depressed, vowed to avenge, so hid in the Hangzhou Xiasha Agricultural Park hardships painstaking practice, and finally practiced into a stunt, can not rest at a constant speed (VR m/s) has been running. The rabbit has been trying to find a chance to teach the turtle a shame before the snow.Recently, HDU held
Comet on Adobe Max to show you from Google spreadsheet, from the Web page and other sources directly to the data into the design manuscript, impressive. This is a clear trend that most applications should support this year.
Real data, whether for design decisions or product decisions, will have a very direct effect. (already have too many products to see the effect of the picture self feeling super good, real one on line dad don't know)

Smart objects
Fortunately, there have been many articles about the power of the Internet of things. Intelligent objects will interact with humans and their surroundings using technologies such as AI and machine learning. The most typical examples are driverless cars, drones, smart kitchens and smart homes that are also emerging. Gartner predicts that these smart objects will become increasingly interconnected and continue to improve our standard of living.

In distributed system, redundant data is the means of guaranteeing reliability, so the consistency maintenance of redundant data is very important. In general, a write operation must update all redundant data to be called a successful end. For example, a data on 5 devices have redundancy, because do not know the reading data will fall on which device, then a write operation, must be 5 devices are updated to complete, write operations to return.For systems with frequent write operations, the bott
