This series of articles is a learning record about the fundamentals of azure services development, and because of time constraints, the process of wishing to discuss and explore yourself is from scratch, to be able to develop basic programming for azure services. There may be a very deep topic relative to each topic, and I would like to have time to do it through other articles. 　　The positioning of this series is basically positioning, take 20-30 minutes, download the code first, follow the article, run to get the relevant experience. The previous article is about Azure queue storage, this is about ...

Hadoop is more suitable for solving big data problems, and relies heavily on its big data storage system, namely HDFS and big data processing system. For MapReduce, we know a few questions.

This article is my second time reading Hadoop 0.20.2 notes, encountered many problems in the reading process, and ultimately through a variety of ways to solve most of the. 　　Hadoop the whole system is well designed, the source code is worth learning distributed students read, will be all notes one by one post, hope to facilitate reading Hadoop source code, less detours. 1 serialization core Technology The objectwritable in 0.20.2 version Hadoop supports the following types of data format serialization: Data type examples say ...

The distributed computing technology proposed by Google makes it easy for developers to develop global application services, and cloud computing technology automates the management of communication, task allocation, and distributed storage among a large number of standardized (heterogeneous) computers. 　　The cloud comes from a decentralized, parallel operation, but better than the grid. Data computing cloud technology can be considered as a sub-set of grid technology, both of which are designed to hide the complexity of the system, so that users need to use it without knowing how the system works inside. The parties follow up with Google to promote cloud services, but the definition is different ...

Uidesigner is the Tencent user research and experience Design Department (CDC) design of a design software, to create a unified platform for designers and team collaboration platform design tools, after 1.0 and 2.0 version of the experience of precipitation, we decided to 3.0 version of the new architecture design. The development of a software system, the early stage of the architecture design bearing the entire software design ideas and key decisions, can be said to be the most important. According to software architecture design ideas, focus on segmentation and interaction, good architecture must make each of the concerns separated from each other. We have the most basic need ...

A small mobile phone application, but all-encompassing, integration of this complex information content or functional logic. To let users get the best experience in the use, quickly grasp the application of the framework structure, the navigation design is an important link. The navigation of mobile apps is similar to the role of signposts or maps in the real world. It is the virtual framework of the application software, which has the function of indicating identity and recognizing the user. For example, as a signpost, navigation can be in use, locate where the user is currently, to highlight the current view of the user important features, tell users where to go, in different views and areas quickly cut ...

What is the traditional brand enterprise to do, how to locate, how to plan the layout? 　　First, the traditional brand enterprises to do, how to position? Before with some traditional big brand merchant exchanges discover, they began to complain and realize that their own operation of the cat or the company can not meet the needs of the group development, it is more difficult to rely on external forces; to express the meaning is: as a traditional brand electric business, in the key channels and large electric business platform to build and layout completed, After a period of grinding and operation of the team on the track, it should be the main focus on the sale of goods from their own mainly out, ...

(This article is published in the "Truth Furniture" magazine March 2014 issue) 2013-year double 11 shopping carnival, incredibly the home appliance merchants on line, named incredibly online. Coincides with a double on the eve of the line 19 China's largest home shopping chain boycott of the cat double A section of the shopping mall to implement its O2O plan, incredibly online debut in this sensitive time, it is inevitable that its choice of the time behind the intention to try to figure out. However, I am concerned about is not incredibly online to choose when on-line, but actually online with the previous traditional home shopping mall to do the electrical business ...

Cloud computing initial fixed investment high, marginal input low, which leads to diminishing marginal cost, marginal income increment. In cloud computing, both infrastructure, platform and software require higher initial fixed inputs. Once built, however, it can be reused over and over again, and each value-added business, with a lower marginal input, can be launched without developing infrastructure, platforms and software from scratch. What is cloud computing? Now is not without answers, but too many answers. Now the answer to "What is cloud computing" is so much that people can't figure out what cloud computing is. ...

The theory of increasing the range of returns 30 years ago, as if it were specifically tailored for cloud computing.　　　　　　 Can just explain the special principles of cloud computing. What is cloud computing? Now is not no answer, but too many answers. Now the answer to "What is cloud computing" is so much that people can't figure out what cloud computing is. The reason is that people just inductive local phenomenon, just grasp the cloud computing this elephant a part of the cloud as a whole. Of course, comprehensive induction, than the local induction is not much better, it makes the cloud computing infinite complexity, trapped ...
