"Core Tip" there is news that in the next two years, China intends to send 10 more Beidou navigation satellite. China's independent development of the Beidou second series of satellites this year began to enter the network peak, is expected to form a global satellite navigation and positioning system in 2015. Analysts point out that the Beidou satellite launch marks a further step towards the establishment of a "local GPs" (Global satellite Positioning System) in China.　　The development of "Beidou" is regarded as the signal of China's military combat capability, and will hopefully get rid of the embarrassment of satellite navigation system eminence by US GPs. Wenchuan disaster relief emerged last year's new China ...

Preface Having been in contact with Hadoop for two years, I encountered a lot of problems during that time, including both classic NameNode and JobTracker memory overflow problems, as well as HDFS small file storage issues, both task scheduling and MapReduce performance issues. Some problems are Hadoop's own shortcomings (short board), while others are not used properly. In the process of solving the problem, sometimes need to turn the source code, and sometimes to colleagues, friends, encounter ...

Since the beginning of cloud computing, the basic process of deploying applications in the cloud has barely changed, by first Deploying application components and database elements, and then connecting them to users over the network. However, the details of how to connect these applications have changed. Because the way you define "network as a service" changes. All along, OpenStack has a clear Naas model in quantum (now Neutron), which is a good example of Naas evolution, and it can be seen that we are constantly moving forward. When setting up a cloud application connection service ...

IBM Smartcloud™init (an IBM SmartCloud support package) is the first startup script developed from an Open-source cloud-init package. It was originally developed in the form of icon bundle in the integration context between Image construction and composition Tools (icon) and IBM SmartCloud Provisioning 1.2 ...
