Core Java Wiki

WikkaWiki is a lightweight wiki engine written in PHP language that uses MySQL database storage for background data. WikkaWiki is a branch variant of the WakkaWiki engine, featuring high speed, scalability, and security. This engine complies with the GNU Public License Agreement GPL. Compared with other heavyweight wiki engines, Wikka wiki does not inherit many of the built-in features, its goal is to ensure that the core code as small as possible, and the scalability of the engine by a number of extension plug-ins to implement, these plug-ins can provide a variety of complex work ...

In the past, we have introduced some principles of software development, such as the 10 commandments of high quality code and the UNIX design principles described in the UNIX legend (next article). I believe that you can learn from middle school some knowledge of design principles, as I said in the "How Do I Recruit procedures", a good programmer usually consists of its operational skills, knowledge level, experience level and ability four aspects. Here I would like to talk about some of the principles of design, I think these things belong to the long-term experience summed up knowledge. These principles should be understood by every programmer. But...

Objective the goal of this document is to provide a learning starting point for users of the Hadoop Distributed File System (HDFS), where HDFS can be used as part of the Hadoop cluster or as a stand-alone distributed file system. Although HDFs is designed to work correctly in many environments, understanding how HDFS works can greatly help improve HDFS performance and error diagnosis on specific clusters. Overview HDFs is one of the most important distributed storage systems used in Hadoop applications. A HDFs cluster owner ...
