machines, and underlying operating system (OS) settings. There are several tools for developers to use when analyzing and optimizing, and you can learn and use them by reading Java tools for Source Code optimization and analyses.It is important to understand that no two applications can use the same optimizations, and there is no perfect reference path for optimizing Java applications. Use best practices and stick with the right way to handle performance optimizations. To achieve true maximum p

whether the frequency of errors has increased. LibratoLibrato is a managed service that helps control and monitor cloud applications. It takes only a few seconds to easily configure a custom monitoring dashboard. Pure language bindings use languages such as Clojure, Java, and so on. Support integration with AWS, Heroku and many other cloud platforms for data collection. Alarm notifications are generated automatically when the monitored indicator exceeds the defined threshold. Librato can e

maximum performance optimization, you, as a Java developer, need to have a proper understanding of the Java Virtual Machine (JVM) and the underlying operating system.Is that I summarize the performance optimization should learn to understand a few knowledge system:V. Concurrent programmingConcurrent programming is almost always a must-ask question for all Internet companies, and concurrent programming is one of the most important skills for Java programmers and one of the hardest skills to mast

architecture is initializedThe architecture also requires architecture verification (like the BVT of the tester ). Therefore, for architects, individual learning ability, learning speed, and practical ability are very important. So how to verify the architecture?1. Find several developers to review the API provided by the review framework and check the feedback. Modify the API if necessary, or solve the problem through technical training.2. Use AOP t

stop and think is the essence of progress.　　5) to be able to write beautiful codeArchitects are not high up, out of code deeds. The architect is first and foremost a good programmer to be able to write the core functions of a project or product, ready to roll up the sleeves to solve problems in the project.The code is not beautiful how to get the shot? How can you convincing?The so-called beautiful code is not only clear, easy to understand, elegant, but also to achieve functionality, no bugs o

distributed environment, consistency means that data from multiple nodes is consistent.(2) Availability (availability): Availability means that the service can always be guaranteed to be available, and when a user makes a request, the service can return the result within a limited time.(3) Partition tolerance (partition fault tolerance): Partition refers to the partition of the network. In general, the key data and services are located in different IDC.The CAP theory tells us that a distributed

Http://sd.csdn.net/n/20060714/92603.html Microsoft's DotNet development is definitely a technology that is easy to get started with and difficult to improve. It is basically impossible to become a DotNet architect without three or more years of coding accumulation. Especially in large software projects, architects are the core members of the Project. Therefore, the RUP methodology also recognizes architecture as the core, reflecting the important role

Lao Meng's blog: Yun: 4. every few years, the programmer circle will erect a new idol school career. Ten years ago, I was a project manager, five years ago I was an architect, and now I am a product manager. The essence behind it is the same, that is, a profession-drawing a little bit on the whiteboard with a marker pen, spraying a few mouthfuls of spams, so that the boss of Sb is stunned, before the fainting, let your little hand wave and direct a bunch of moles behind you to hide and kill t

. As long as there are things to repeat more than 3 times, consider whether automation is required.If you don't do devops, as your business grows and your system grows, you will eventually need to transform it from beginning to end. It is better to start the construction of the pre-design considerations, in fact, these things if you understand, the beginning of the good, do not waste too much time, but can save a lot of time, why not.

above two books are the classic masterpiece of rod Johnson, a must-read book for Java architects. Among the books I have recommended, I have read the most carefully and seriously. At that time, I almost read this book in an out-of-the-box manner, when I was a child, I picked up the lights and went to night to read Jin Yong's martial arts novels. The content in the book, as well as my own experience and knowledge, were thoroughly summed up. After read

should have been very skillful in using Java programming and have a good programming idea and habit,However, you may still lack the ability to grasp the overall architecture of the application software. Now you are the first step towards the architect. 1.

But it seems that this book does not have a Chinese translation. 2. Expert one-on-one J2EE

By Jon Ji 2011/8/20 Coding standards often only define the specific programming format and detailed requirements, but for improving the programming capability of software personnel, programming rules are more valuable, I will give some of my views and ideas for your reference.
