The release of the Java version of almost all platforms involves all aspects of the Java language itself and the JVM. So for Java 7, from the JSR draft, we get the high-level goal of Java 7: Compatibility--Any program that runs on previous versions must be able to run in Java SE 7 without making any changes; development efficiency--improve development efficiency, minimal learning curve; performance--New parallel API Interface, introduces a real asynchronous I/O AP ...
When Microsoft first released its Windows Azure cloud computing architecture, I felt a little weird. Even beginning to support non-C # developers working on the Java SDK, putting different applications on Microsoft's new cloud. However, most updates are designed to simplify the deployment of Azure cloud applications for a wide variety of .NET, not Java or anything else. An exception is the trend of ".NET-based" Azure. Earlier this year, interoperability expert JNBridge released JNBridge ...
The road to computer science is littered with things that will become "the next big thing". Although many niche languages do find some place in scripts or specific applications, C (and its derivatives) and Java languages are hard to replace. But Red Hat's Ceylon seems to be an interesting combination of some language features, using the well-known C-style syntax, but it also provides object-oriented and some useful functional support in addition to simplicity. Take a look at Ceylon and see this future VM ...

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 ...
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...
Introduction: It is well known that R is unparalleled in solving statistical problems. But R is slow at data speeds up to 2G, creating a solution that runs distributed algorithms in conjunction with Hadoop, but is there a team that uses solutions like python + Hadoop? R Such origins in the statistical computer package and Hadoop combination will not be a problem? The answer from the king of Frank: Because they do not understand the characteristics of R and Hadoop application scenarios, just ...
Seed7 is a higher-level open source general-purpose programming language than Ada, c++++ and Java, designed and developed by Thomas Mertes. Seed7 's new statements and operators can be easily compiled, with the same type of results and type parameters more elaborate than the concept of a template or generic. Its salient features are object-oriented, although Seed7 contains some concepts of other programming languages, but it has many different features from other programming languages, including: as an extensible programming language, it supports user-defined statements and operations. ...
