New technologies help you solve problems with high WiFi costs
Are you still worried about your WiFi? Don't worry. Recently, a team of computer scientists and electrical engineers from the University of Washington has developed a very efficient Wi-Fi wireless network technology.What are the main features of new configurations?
Researchers at the University of Washington who participated in the development of this technology have demonstrated that weak radio signals can indeed meet the power nee

And this book is actually translated by the end of 2014 published "Building MicroServices", and before the English version of the book, in early 2014, the technical framework of the architect of Martin Fowler has written a lot about the system to explore the micro-service articles. And in the 2011 an

C---consistency consistency
A---availability of availability
P---Partition tolerance zoning tolerance
This theorem originates from the computer scientist Eric Brour of the University of California (University of California, Berkeley) in the 2000 Distributed Computing Principle

12. Working effectively with Legacy code I like this book because almost all software developers, at some point in their career, often have to support and work with legacy systems. In this book, Michael feathers provides strategies from start to finish to work more effectively with untested legacy code repositories. This book draws on Michael's material for his famous object Mentor Symposium: Michael's te
understand the cap theory is to imagine two nodes on each side of the partition. Allowing at least one node to update the state results in inconsistent data, i.e. the loss of C nature. If the node on the partition side is set to not be available for data consistency, the A property is lost. Unless two nodes can communicate with each other, both C and a are guaranteed, which can lead to the loss of P-Properties.This theorem originates from the computer scientist Eric Brour of the University of C
, thus eliminating huge islands of information in Internet environment, realizing information sharing, exchanging data and achieving information consistency. Web services wants to achieve a "web-based seamless integration" goal by enabling different systems to invoke each other in a "software-software Conversation" way, breaking the state of incompatibility between software applications, Web sites, and various devices.
In April this year, the consortium convened its first Web Services
Product innovation is the most important way for network operators to obtain high profits, and many network operators have begun to adjust their business direction. Surveys show that 78% of the network operators believe that the "Network marketing Capacity" is the network business in the first necessary ability to do business, followed by the "integration of the resources of the capacity", about 68% of the network operators agree; ranked third is the "product innovation capability" to get 67% of
GI (q) using δ1, which points to the other hash buckets in the hash table.By using multiple perturbation vectors, we can locate multiple hash buckets to obtain more near-neighbor candidates for the query value Q.
