  • Build Lightning Fast Web Apps with HTML5 and SAS® Allan Bowe, SAS Consultant
    1091-2017 Build Lightning Fast Web Apps with HTML5 and SAS® Allan Bowe, SAS consultant ABSTRACT What do we want? Web applications! When do we want them? Well.. Why not today? This author argues that the key to delivering web apps ‘lightning fast’ can be boiled down to a few simple factors, such as: • Standing on the shoulders (not the toes) of giants. Specifically, learning and leveraging the power of free / open source toolsets such as Google’s Angular, Facebook’s React.js and Twitter Bootstrap • Creating ‘copy paste’ templates for web apps that can be quickly re-used and tweaked for new purposes • Using the right tools for the job (and being familiar with them) By choosing SAS as the back end, your apps will benefit from: • Full blown analytics platform • Access to all kinds of company data • Full SAS metadata security (every server request is metadata validated) By following the approach taken in this paper, you may well find yourself in possession of an electrifying capability to deliver great content and professional-looking web apps faster than one can say “Usain Bolt”. AUDIENCE This paper is aimed at a rare breed of SAS developer – one with both front end (HTML / Javascript) and platform administration (EBI) experience. If you can describe the object of object arrays, the object spawner and the Document Object Model – then this paper is (objectionably?) for you! INTRODUCTION You are about to receive a comprehensive overview of building Enterprise Grade web applications with SAS. Such a framework will enable you to build hitherto unimaginable things.

  • A Webrtc Video Chat Implementation Within the Yioop Search Engine
    A WebRTC Video Chat Implementation Within the Yioop Search Engine A Project Presented to The Faculty of the Department of Computer Science San Jose State University In Partial Fulfillment of the Requirements for the Degree Master of Science By Yangcha K. Ho May 2019 ©2019 Yangcha K. Ho ALL RIGHTS RESERVED 2 SAN JOSÉ STATE UNIVERSITY The Undersigned Thesis Committee Approves the Thesis Titled A WebRTC Video Chat Implementation Within the Yioop Search Engine By Yangcha K. Ho APPROVED FOR THE DEPARTMENT OF COMPUTER SCIENCE ___________________________________________________________ Dr. Chris Pollett, Department of Computer Science 05/20/2019 __________________________________________________________ Dr. Melody Moh, Department of Computer Science 05/20/2019 _________________________________________________________ Dr. Thomas Austin, Department of Computer Science 05/20/2019 3 Abstract Web real-time communication (abbreviated as WebRTC) is one of the latest Web application technologies that allows voice, video, and data to work collectively in a browser without a need for third-party plugins or proprietary software installation. When two browsers from different locations communicate with each other, they must know how to locate each other, bypass security and firewall protections, and transmit all multimedia communications in real time. This project not only illustrates how WebRTC technology works but also walks through a real example of video chat-style application. The application communicates between two remote users using WebSocket and the data encryption algorithm specified in WebRTC technology. This project concludes with a description of the WebRTC video chat application’s implementation in Yioop.com, a PHP-based internet search engine. 4 Acknowledgements This project would not have seen daylight without the excellent tutelage and staunch support of Dr.

  • Rich Internet Applications for the Enterprise
    Final Thesis Rich Internet Applications for the Enterprise A comparative study of WebWork and Java Web Start by Emil Jönsson LITH-IDA-EX–07/063–SE 2007-12-07 Linköping University Department of Computer and Information Science Final Thesis Rich Internet Applications for the Enterprise A comparative study of WebWork and Java Web Start by Emil Jönsson LITH-IDA-EX–07/063–SE Supervisors: Valérie Viale Amadeus Philippe Larosa Amadeus Examiner: Kristian Sandahl Department of Computer and Information Science Linköping University Abstract Web applications initially became popular much thanks to low deployment costs and programming simplicity. However, as business requirements grow more complex, limitations in the web programming model might become evident. With the advent of techniques such as AJAX, the bar has been raised for what users have come to expect from web applications. To successfully implement a large-scale web application, software developers need to have knowledge of a big set of complementary technologies. This thesis highlights some of the current problems with the web programming model and discusses how using desktop technologies can improve the user experience. The foundation of the thesis is an implementation of a prototype of a central hotel property management system using web technologies. These technologies have then been compared to an alternative set of technologies, which were used for implementing a second prototype; a stand-alone desktop client distributed using Java Web Start. Keywords: web development, Rich Internet Applications, WebWork, Java Web Start, Property Management System, hospitality software Acknowledgements First I would like to thank Amadeus for giving me the opportunity to do an internship at their development site in Sophia Antipolis.

  • Webbrowser Webpages
    Web Browser A web browser, or simply "browser," is an application used to access and view websites. Common web browsers include Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, and Apple Safari. The primary function of a web browser is to render HTML, the code used to design or "markup" web pages. Each time a browser loads a web page, it processes the HTML, which may include text, links, and references to images and other items, such as cascading style sheets and JavaScript functions. The browser processes these items, then renders them in the browser window. Early web browsers, such as Mosaic and Netscape Navigator, were simple applications that rendered HTML, processed form input, and supported bookmarks. As websites have evolved, so have web browser requirements. Today's browsers are far more advanced, supporting multiple types of HTML (such as XHTML and HTML 5), dynamic JavaScript, and encryption used by secure websites. The capabilities of modern web browsers allow web developers to create highly interactive websites. For example, Ajax enables a browser to dynamically update information on a webpage without the need to reload the page. Advances in CSS allow browsers to display a responsive website layouts and a wide array of visual effects. Cookies allow browsers to remember your settings for specific websites. While web browser technology has come a long way since Netscape, browser compatibility issues remain a problem. Since browsers use different rendering engines, websites may not appear the same across multiple browsers. In some cases, a website may work fine in one browser, but not function properly in another.

  • 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).
