Web applications are replacing traditional native applications in recent years. For web applications, javascript is the most extensively used client side programming languages. The large javascript codebase often makes applications hard to understand, maintain and extend. Call graph is a human understandable program representation that can be used as a basis for maintenance and further extension of the application. In maintenance phase call graph can play a vital role by facilitating developers to easily trace the code that implements a particular feature. There is insufficient tool support for generating call graph for javascript. For its dynamic nature, javascript call graph generation becomes challenging. We present a dynamic analysis based mechanism to construct the call graph of javascript of a client side web application. Our evaluation on web applications demonstrates that the technique is precise and the rate of unidentified nodes in call graph is acceptable.

The cloud computing model leads to the increased penetration of the web applications in the office environment. Designed in many cases to replace traditional desktop software, web applications still lack many of the valuable features present on the desktop that increase usability and productivity. Due to the highly isolated design of the browser, it is currently impossible for web applications to communicate with desktop environment, which usually means sending messages or receiving event notifications. This is often required in order to let the person using the application know about the important events happening in the minimized browser window. By contrast traditional applications can take the control of the desktop at any time. The paper introduces the Web4Desktop framework, a browser/client based architecture designed to overcome these limitations by proving a secure infrastructure that allows web applications to communicate with any desktop software implementing the Web4Desktop API. The framework can be utilized to add desktop integration to existing web applications, a step that requires only minimal changes in the web application's code and greatly improve the user experience because these applications will start to behave more like desktop software.

This paper presents how it is possible to utilize PLC in the task of the Web server. Described is configuration of the PLC and its connection to the computer network. Next is described principle of creation dynamic web page and described are function for process variable data read and write. User can create dynamic web page that uses combination of some programming language e. g. HTML, ASP (Active Server Pages) and java script. The process variables can be displayed on remote PC independently on operating system. There is only web browser needed. In the paper is also described principle of the desktop application that was programmed in the java language. This application directly communicates with remote PLC and has own visualization of the technological process. For communication with the PLC the opened and wide HTTP web protocol is used. Described principles present some alternative for well-known technology OPC. Inscribed principles were verified in application for temperatures measurement in the underground gasification process and for system of indirect temperature measurement.

Detecting Function Purity in javascript 15

Detecting Function Purity in JavaScript

We present an approach to detect function purity in javascript. A function is pure if none of its applications cause observable side-effects. The approach is based on a pushdown flow analysis that besides traditional control and value flow also keeps track of write effects. To increase the precision of our purity analysis, we combine it with an intraprocedural analysis to determine freshness of variables and object references. We formalize the core aspects of our analysis, and discuss our implementation used to analyze several common javascript benchmarks. Experiments show that our technique is capable of detecting function purity, even in the presence of higher-order functions, dynamic property expressions, and prototypal inheritance.

With the development of Artificial Intelligence, gesture recognition technology has been applied in practical schemes. We built up the Dynamic Matrix Sound system（DMS system） which makes an excellent sound field reproduction effect. However, because of the weak controllability of the large-scale system, the application of the DMS system is very limited. In order to control a DMS system by gesture, the Leap Motion is adopted and the *** is used to connect the DMS system with client terminal. The real time 3 D gesture position data, which is captured by leap motion, will be translated into DMS control instruction and transferred to the DMS system to implement the play, pause and other functions. In order to support a wider range of client hardware, the design is realized by javascript and C++, of which the data communication between them is realized through ***. In the design of the system, the whole process is to transfer the communication logic of websocket to the ***, so that the communication between the mobile devices and the back-end is more reasonable.

The Environment Development Branch (ED), United States Joint Staff J7 (JS J7), formerly the Joint Forces Command (JFCOM) J7, supports a variety of simulation environment development activities in concert with NATO and Partnership for Peace (PfP) countries. Recent activities include development of the NATO Training Federation (NTF) in support of an experiment running in parallel with the "traditional" Southeastern Europe Simulation (SEESIM) training exercise, support for NATO Research & Technology Organization (RTO) Task Group MSG-106, Enhanced CAX Architecture, Design and Methodology, and development of NTF to support NATO Joint Force training. This paper introduces each of these activities, discusses synergies achieved among them, and addresses the influence JS J7 participation in NATO/PfP activities has had on ED development activities in support of US Joint Force training.

Based on a systematic review of empirical studies about software components selection and usability techniques applied to a functional prototype, this article maps the functional and non-functional requirements of a components sharing network that aims to accelerate javascript software development. Results point out that integrating the development environment to a component search mechanism with automated filters, ordered by quality criteria, and allow code snippets rank and improvements submission on a version control system are the path to accelerate the development and motivate IT students and professionals to participate in this network.

Live programming is an idea espoused by programming environments from the earliest days of computing (such as Lisp machines and SmallTalk) but have since lain dormant. Recently, the prevalence of asynchronous feedback in programming languages such as javascript and advances in visualizations and user interfaces have lead to a resurgence of live programming in online education communities (such as Khan Academy) and in experimental IDEs (such as LightTable). The LIVE 2013 workshop includes 11 papers describing visions, implementations, mashups, and new directions of live programming environments. The participants include both practitioners of live coding and researchers in programming languages and software engineering. Finally, several demos curated on the live workshop page are presented.

Drive-by download attacks force users to automatically download and install malware by redirecting them to malicious URLs that exploit vulnerabilities of the user's web browser. Attackers profile the information on the user's environment such as the name and version of the browser and browser plugins and launch a drive-by download attack on only certain targets by changing the destination URL. When malicious content detection and collection techniques such as honeyclients are used that do not match the specific environment of the attack target, they cannot detect the attack because they are not redirected. We propose here a method to exhaustively analyze javascript code relevant to redirections and to extract the destination URLs in the code. Our method facilitates the detection of attacks by extracting a large number of URLs while controlling the analysis overhead by excluding code not relevant to redirections. We implemented our method in a browser emulator called MINESPIDER that automatically extracts potential URLs from websites. We validated it by using communication data with malicious websites captured during a three-year period. The experimental results demonstrated that MINESPIDER extracted 30,000 new URLs from websites in a few seconds that existing techniques missed.
