1, callable: Callable The task that returns the result and may throw an exception. The implementing person defines a method called call without any arguments. The callable interface is similar to Runnable, both of which are designed for classes whose instances might be executed by another thread. However, Runnable does not return a result and cannot throw a checked exception. The Executors class contains some practical methods for converting from other common forms into callable classes. Cal

Ajax "IT168" Ajax is a combination of several sophisticated technologies designed to give users a more satisfying user experience from Web applications. This paper reviews the evolution of enterprise application architecture and tries to expound that Ajax is the inevitable product of B/s architecture development, but Ajax seems to have a bleak future because of the congenitally deficient JavaScript programming language that Ajax relies on for survival

With future upgrades to file system protocols, such as NFS (including concurrent NFS, or PNFS), will NFS potentially replace many of the existing proprietary file systems? Let's take digitalfilm tree for example, a company in Hollywood that provides post-processing and virtual effects services for the entertainment industry. The company employs products that include Apple Xsan, HP storageworks arrays, QLogic switches, and other storage vendors. They

The previous chapter describes the Future type and how to use it to write high readability, high combination asynchronous execution code. Future is just one part of the whole puzzle: it is a read-only type that allows you to use it to compute the value, or to handle errors that occur in calculations. But before that, there has to be a way to put that value in. In this chapter, you will see how to achieve th

-mobile-development I used the ipad to see why I think the experience is far inferior to that of the native app. However, I agree that web apps are a trend. In the long run, html and app complement each other, while html can be considered for cross-platform scenarios. In addition, 'html5' is abused. In fact, it is a collection of various web technologies such as html, js, and css. If this concept is not thoroughly studied, html5 is enthusiastically pr

Past, present, and future of Web attack Log Analysis0x00: Preface When talking about log analysis, most people feel that this is an afterthought behavior. When hackers succeed, the website will be hacked. When an operator finds out, the security personnel will intervene in the analysis of the intrusion causes. By analyzing hacker attacks, they will often trace back the logs of the past few days or even longer.0x01: processing process. I personally t
