The famous Tiobe rankings are ranked in programming languages every month, explaining which programming languages are more widely used. Have you considered the influence of these programming languages on each other? Which language has the greatest influence? Obviously, most developers will think their language is the best.   If you want a more scientific view, you can view the following programming language impact diagram. Influence between programming languages the figure is implemented by Ramio Gómez, each node in the diagram represents ...

Foreword in the first article of this series: using Hadoop for distributed parallel programming, part 1th: Basic concepts and installation deployment, introduced the MapReduce computing model, Distributed File System HDFS, distributed parallel Computing and other basic principles, and detailed how to install Hadoop, How to run a parallel program based on Hadoop in a stand-alone and pseudo distributed environment (with multiple process simulations on a single machine). In the second article of this series: using Hadoop for distributed parallel programming, ...

Microsoft James Black, serif; Font-size:10.5pt "> in the author's personal more than 10 years of it practice, is a software product and service research and development of the old dog." I have experienced the first wave of the Internet, and now this is the golden age of IT technology development, whether traditional enterprise software, or Internet services, its development is particularly rapid. These two forces in parallel development, but also a slow convergence. This article mainly discusses the internet trend of enterprise software from the view of technology, content, demand and mode.

People often ask me if they really should believe in Oss. In other words, the worry is: is the OSS the angel that brings us a good life, or is it a demon that destroys our lives? As a matter of fact, this problem has been raised since the beginning of Linux and various BSD (Berkeley Software distribution) operating systems. In reality, any organization or enterprise is very cautious in planning to use a free software that is not from a reputable merchant. As a routine, generally ...

An overview of the number of wireless devices, the diversity of communication standards, and the complexity of modulation schemes are increasing every year.    And with each generation of new technology, the use of traditional technology to test wireless equipment, the need for a large number of more sophisticated testing equipment, the cost is also increasing. The use of virtual (software) instrumentation combined with modular I/O is a way to minimize hardware costs and reduce test time. A new approach to software design instruments allows RF test engineers to reduce testing at multiple order of magnitude without the need for custom or special standard instruments.
