A Trusted Infrastructure for Symbolic Analysis of Event-Driven Web
A Trusted Infrastructure for Symbolic Analysis of Event-Driven Web Applications Gabriela Sampaio Imperial College London, UK [email protected] José Fragoso Santos INESC-ID/Instituto Superior Técnico, Universidade de Lisboa, Portugal Imperial College London, UK [email protected] Petar Maksimović Imperial College London, UK [email protected] Philippa Gardner Imperial College London, UK [email protected] Abstract We introduce a trusted infrastructure for the symbolic analysis of modern event-driven Web applica- tions. This infrastructure consists of reference implementations of the DOM Core Level 1, DOM UI Events, JavaScript Promises and the JavaScript async/await APIs, all underpinned by a simple Core Event Semantics which is sufficiently expressive to describe the event models underlying these APIs. Our reference implementations are trustworthy in that three follow the appropriate standards line-by-line and all are thoroughly tested against the official test-suites, passing all the applicable tests. Using the Core Event Semantics and the reference implementations, we develop JaVerT.Click, a symbolic execution tool for JavaScript that, for the first time, supports reasoning about JavaScript programs that use multiple event-related APIs. We demonstrate the viability of JaVerT.Click by proving both the presence and absence of bugs in real-world JavaScript code. 2012 ACM Subject Classification Software and its engineering → Formal software verification; Software and its engineering → Software testing and debugging Keywords and phrases Events, DOM, JavaScript, promises, symbolic execution, bug-finding Digital Object Identifier 10.4230/LIPIcs.ECOOP.2020.28 Acknowledgements Fragoso Santos, Gardner, and Maksimović were partially supported by the EPSRC Programme Grant ‘REMS: Rigorous Engineering for Mainstream Systems’ (EP/K008528/1) and the EPSRC Fellowship ‘VetSpec: Verified Trustworthy Software Specification’ (EP/R034567/1). -

Web Messaging and Notification System Between Journalists And
FACULDADE DE ENGENHARIA DA UNIVERSIDADE DO PORTO Web messaging and notification system between journalists and citizens Cláudia Margarida da Rocha Marinho Mestrado Integrado em Engenharia Informática e Computação Supervisor: Maria Teresa Magalhães da Silva Pinto de Andrade Second Supervisor: Pedro Miguel da Silva Santos July 19, 2019 Web messaging and notification system between journalists and citizens Cláudia Margarida da Rocha Marinho Mestrado Integrado em Engenharia Informática e Computação Approved in oral examination by the committee: Chair: Jorge Manuel Gomes Barbosa (Assistant Professor) External Examiner: Paula Viana (Coordinator Professor) Supervisor: Maria Teresa Andrade (Assistant Professor) July 19, 2019 Abstract Over the recent years, live streaming has become a popular trend among events’ attendees, al- lowing them to share their own experiences of the event with people around the world. Realizing that this might be an opportunity for content providers to enrich their coverage of large events by making use of the attendees’ contributions, MOG Technologies started a project in a partnership with INESC TEC, Jornal de Notícias and OSTV. The idea of the project is to offer simple means for the event attendees, who can be general public or professional reporters, to send video streams in real-time to the TV producer who is covering the event and live broadcasting it to the public. The video streams are captured with the smartphones of the attendees through an intuitive web app. On the production side, the intention is to allow the TV event producer to continuously browse through the different received feeds using a drag-and-drop web-based GUI and, at any instant, to select a given feed to be inserted automatically in the main broadcast stream, which can also appear in the on-site large TV screens. -

Standards for Web Applications on Mobile: Current State and Roadmap
Standards for Web Applications on Mobile: current state and roadmap January 2014 Latest version http://www.w3.org/Mobile/mobile-web-app-state/ This version http://www.w3.org/2014/01/mobile-web-app-state/ (PDF version) Previous version http://www.w3.org/2013/09/mobile-web-app-state/ Web technologies have become powerful enough that they are used to build full-featured applications; this has been true for many years in the desktop and laptop computer realm, but is increasingly so on mobile devices as well. This document summarizes the various technologies developed in W3C that increase the capabilities of Web applications, and how they apply more specifically to the mobile context. A good subset of these technologies are described and explained in the W3C on-line training on programming Web applications. 1.

Challenges for Enabling Targeted Multi-Screen Advertisement for Interactive TV Services for the Fourth W3C Web and TV Workshop
Position Paper: Challenges for enabling targeted multi-screen advertisement for interactive TV services for the Fourth W3C Web and TV Workshop Christopher Krauss, Louay Bassbouss, Stefan Pham, Stefan Kaiser, Stefan Arbanowski, Stephan Steglich Fraunhofer Institute for Open Communication Systems Kaiserin-Augusta-Allee 31, 10589 Berlin, Germany ffi[email protected] February 3, 2014 The Fraunhofer Institute FOKUS1 Competence Center Future Applications and Media FAME2 re- searches and develops in the fields of interactive smart and social media services, cross-platform applica- tions as well as personalized service offerings. All technical solutions comply with applicable international standards, such as DASH IF, the Open IPTV Forum, HbbTV and W3C. In this context, the theme of the FAME organized 4th FOKUS Media Web Symposium3 on May 8 - 9, 2014 is "Internet delivered Media and Multi-screen Technologies and Standards". In this position paper we will address the challenges and missing standards for enabling targeted multi-screen advertisement for interactive TV services. Furthermore, we will outline and discuss the limitations and difficulties of building cross-platform and multi-screen TV services. We will also propose potential solutions for closing the gap between the web and TV domains based on the following use case: Alice and Bob are watching a Formula 1 race on the TV. The broadcaster offers a service which allows users watch the race from different camera perspectives, where the TV displays the perspective of the main camera and a companion device may be used to display the perspective of the on-board camera of a selected driver (user can select which driver). -

Nelson Traditionally, general web services used only the GET and POST methods of HTTP while several other HTTP methods like PUT, PATCH, and DELETE were rarely utilized. Additionally, the Web was mainly navigated by humans using web browsers and clicking on hyperlinks or submitting HTML forms. Clicking on a link is always a GET request while HTML forms only allow GET and POST methods. -
