Effects and Opportunities of Native Code Extensions For
Effects and Opportunities of Native Code Extensions for Computationally Demanding Web Applications DISSERTATION zur Erlangung des akademischen Grades Dr. Phil. im Fach Bibliotheks- und Informationswissenschaft eingereicht an der Philosophischen Fakultät I Humboldt-Universität zu Berlin von Dipl. Inform. Dennis Jarosch Präsident der Humboldt-Universität zu Berlin: Prof. Dr. Jan-Hendrik Olbertz Dekan der Philosophischen Fakultät I: Prof. Michael Seadle, Ph.D. Gutachter: 1. Prof. Dr. Robert Funk 2. Prof. Michael Seadle, Ph.D. eingereicht am: 28.10.2011 Tag der mündlichen Prüfung: 16.12.2011 Abstract The World Wide Web is amidst a transition from interactive websites to web applications. An increasing number of users perform their daily computing tasks entirely within the web browser — turning the Web into an important platform for application development. The Web as a platform, however, lacks the computational performance of native applications. This problem has motivated the inception of Microsoft Xax and Google Native Client (NaCl), two independent projects that fa- cilitate the development of native web applications. Native web applications allow the extension of conventional web applications with compiled native code, while maintaining operating system portability. This dissertation determines the bene- fits and drawbacks of native web applications. It also addresses the question how the performance of JavaScript web applications compares to that of native appli- cations and native web applications. Four application benchmarks are introduced that focus on different performance aspects: number crunching (serial and parallel), 3D graphics performance, and data processing. A performance analysis is under- taken in order to determine and compare the performance characteristics of native C applications, JavaScript web applications, and NaCl native web applications. -

Automated Testing Clinic Follow-Up: Capybara-Webkit Vs. Poltergeist/Phantomjs | Engineering in Focus
Automated Testing Clinic follow-up: capybara-webkit vs. polter... https://behindthefandoor.wordpress.com/2014/03/02/automated-... Engineering in Focus the Fandor engineering blog Automated Testing Clinic follow-up: capybara-webkit vs. poltergeist/PhantomJS with 2 comments In my presentation at the February Automated Testing SF meetup I (Dave Schweisguth) noted some problems with Fandor’s testing setup and that we were working to fix them. Here’s an update on our progress. The root cause of several of our problems was that some of the almost 100 @javascript scenarios in our Cucumber test suite weren’t running reliably. They failed occasionally regardless of environment, they failed more on slower CPUs (e.g. MacBook Pros only a couple of years old), when they failed they sometimes hung forever, and when we killed them they left behind webkit-server processes (we were using the capybara-webkit driver) which, if not cleaned up, would poison subsequent runs. Although we’ve gotten pretty good at fixing flaky Cucumber scenarios, we’d been stumped on this little handful. We gave up, tagged them @non_ci and excluded them from our build. But they were important scenarios, so we had to run them manually before deploying. (We weren’t going to just not run them: some of those scenarios tested our subscription process, and we would be fools to deploy a build that for all we knew wouldn’t allow new users to subscribe to Fandor!) That made our release process slower and more error-prone. It occurred to me that I could patch the patch and change our deployment process to require that the @non_ci scenarios had been run (by adding a git tag when those scenarios were run and checking for it when deploying), but before I could put that in to play a new problem appeared. -
AJAX and Jquery L Raw AJAX Handling in JS Is Very Tedious L Jquery Provides Flexible and Strong Support to Handle AJAX Interactions Through a Set of Jquery Functions

Web Browser a C-Class Article from Wikipedia, the Free Encyclopedia
Web browser A C-class article from Wikipedia, the free encyclopedia A web browser or Internet browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page, image, video, or other piece of content.[1] Hyperlinks present in resources enable users to easily navigate their browsers to related resources. Although browsers are primarily intended to access the World Wide Web, they can also be used to access information provided by Web servers in private networks or files in file systems. Some browsers can also be used to save information resources to file systems. Contents 1 History 2 Function 3 Features 3.1 User interface 3.2 Privacy and security 3.3 Standards support 4 See also 5 References 6 External links History Main article: History of the web browser The history of the Web browser dates back in to the late 1980s, when a variety of technologies laid the foundation for the first Web browser, WorldWideWeb, by Tim Berners-Lee in 1991. That browser brought together a variety of existing and new software and hardware technologies. Ted Nelson and Douglas Engelbart developed the concept of hypertext long before Berners-Lee and CERN. It became the core of the World Wide Web. Berners-Lee does acknowledge Engelbart's contribution. The introduction of the NCSA Mosaic Web browser in 1993 – one of the first graphical Web browsers – led to an explosion in Web use. Marc Andreessen, the leader of the Mosaic team at NCSA, soon started his own company, named Netscape, and released the Mosaic-influenced Netscape Navigator in 1994, which quickly became the world's most popular browser, accounting for 90% of all Web use at its peak (see usage share of web browsers). -
Automated Testing of Your Corporate Website from Multiple Countries with Selenium Contents
presents Automated Testing of Your Corporate Website from Multiple Countries with Selenium Contents 1. Summary 2. Introduction 3. The Challenges 4. Components of a Solution 5. Steps 6. Working Demo 7. Conclusion 8. Questions & Answers Summary Because of the complexities involved in testing large corporate websites and ecommerce stores from multiple countries, test automation is a must for every web and ecommerce team. Selenium is the most popular, straightforward, and reliable test automation framework with the largest developer community on the market. This white paper details how Selenium can be integrated with a worldwide proxy network to verify website availability, performance, and correctness on a continuous basis. Introduction Modern enterprise web development teams face a number of challenges when they must support access to their website from multiple countries. These challenges include verifying availability, verifying performance, and verifying content correctness on a daily basis. Website content is presented in different languages, website visitors use different browsers and operating systems, and ecommerce carts must comprehend different products and currencies. Because of these complexities involved, instituting automated tests via a test automation framework is the only feasible method of verifying all of these aspects in a repeatable and regular fashion. Why automate tests? Every company tests its products before releasing them to their customers. This process usually involves hiring quality assurance engineers and assigning them to test the product manually before any release. Manual testing is a long process that requires time, attention, and resources in order to validate the products’ quality. The more complex the product is, the more important, complex, and time- consuming the quality assurance process is, and therefore the higher the demand for significant resources. -
EMERGING TECHNOLOGIES Dymamic Web Page Creation
Language Learning & Technology January 1998, Volume 1, Number 2 http://llt.msu.edu/vol1num2/emerging/ pp. 9-15 (page numbers in PDF differ and should not be used for reference) EMERGING TECHNOLOGIES Dymamic Web Page Creation Robert Godwin-Jones Virginia Comonwealth University Contents: • Plug-ins and Applets • JavaScript • Dynamic HTML and Style Sheets • Instructional Uses • Resource List While remaining a powerful repository of information, the Web is being transformed into a medium for creating truly interactive learning environments, leading toward a convergence of Internet connectivity with the functionality of traditional multimedia authoring tools like HyperCard, Toolbook, and Authorware. Certainly it is not fully interactive yet, but that is undeniably the trend as manifested in the latest (version 4) Web browsers. "Dynamic HTML," incorporated into the new browsers, joins plug-ins, Web forms, Java applets, and JavaScript as options for Web interactivity. Plug-ins and Applets While Web pages are beginning to behave more like interactive applications, traditional authoring tools are themselves becoming Internet-savvy, primarily through the use of "plug-in" versions of players which integrate with Web browsers. The most commonly used plug-in today is Macromedia's "Shockwave," used to Web-enable such applications as Director, Authorware, and Flash. "Shocked" Web pages can be very interactive and provide a visually appealing means of interacting with users (as in some sample ESL exercises from Jim Duber). Plug-ins are easy to use -- they just need to be downloaded and installed. Some come bundled with Netscape and Microsoft's browsers, which simplifies considerably the installation process (and gives developers the confidence that most users will actually have the plug-in installed). -

Interstitial Content Detection Arxiv:1708.04879V1 [Cs.CY] 13 Aug
Interstitial Content Detection Elizabeth Lucas, Mozilla Research August 2017 Abstract Interstitial content is online content which grays out, or otherwise obscures the main page content. In this technical report, we discuss exploratory research into detecting the presence of interstitial content in web pages. We discuss the use of computer vision techniques to detect interstitials, and the potential use of these techniques to provide a labelled dataset for machine learning. 1. Introduction The structure and underlying nature of content in the web is fundamentally different than most rigorously structured data, and often requires deviating from the traditional approaches of recognizing patterns in more heavily structured data. Within the types of content on the web, interstitials are of interest due to their interrupting of the user's web experience. This report represents the preliminary research necessary to explore the structure of interstitial content, and the beginnings of a machine learning application to assist with our understanding of web content and interstitials. The scripts used for data collection and evaluation are available [1]. 1.1. Definitions For the purpose of this research project, `interstitials', or `interstitial content', are defined as online content, often advertisements or other promotional content, which grays out or otherwise obscures the main page content. These interstitials often require the user to interact in order to return to the main content, interrupting the user's experience. `Servo' refers to the Servo browser engine, sponsored by Mozilla Research [6]. Written in the Rust programming language, this modern parallel browser engine aims to improve performance, security, modularity, and parallelization. Future work will involve eventually bringing interstitial ad detection into the Servo browser engine itself. -
