Ponente: Victor Orozco (Guatemala) / Descripción: Cuando hablamos de ECMAScript, nos referimos al estándar que ya va por la versión ES6 y determina cómo emplear el lenguaje Javascript. TypeScript es un lenguaje de programación libre y de código abierto desarrollado y mantenido por Microsoft. Es un superconjunto de JavaScript, que esencialmente añade tipos estáticos y objetos basados en clases. En este webinar se mostrara las novedades de ECMAScript 6 y la potencia del lenguaje de programación TypeScript.

Mobile Digital TV (MDTV), the hybrid of Digital Television (DTV) and mobile devices (such as mobile phones), has introduced a new way for people to watch DTV and has brought new opportunities for development in the DTV industry. Nowadays, the development of the next generation MDTV service has progressed in terms of both hardware layers and software, with interactive services/applications becoming one of the future MDTV service trends. However, current MDTV interactive services still lack in terms of attracting the consumers and the service creation and implementation process relies too much on commercial solutions, resulting in most parts of the process being proprietary. In addition, this has increased the technical demands for developers as well as has increased substantially the cost of producing and maintaining MDTV services. In light of the aforementioned situation, the Thesis has contributed to this field, by proposing an innovative MDTV service creation and consumption system based on XHTML and Java ME. On the head-end it introduces a semi-automatic creation mechanism to facilitate a less technical and more efficient interactive service creation process. This enables designers and creative individuals to be actively involved in the MDTV service creation process and to develop interactive-rich MDTV service. On the client-end it employs an open-source software environment as the interactive service MDTV consumption platform, rendering the MDTV service implementation process as less proprietary as possible. Furthermore, the Thesis offers a discussion on the different MDTV interactive application models currently used and based on the proposed software, a novel MDTV service presentation method is further introduced and adopted instead of the Rich Media and ECMAScript based methods. Finally, a series of qualitative testing procedures have been implemented with regards to conducting an essential evaluation on the operability of the proposed software system.

In this work we present the design and implementation of a platform for automated measurement of the use of JavaScript APIs in a web browser. This platform is based on OpenWPM, which is used to instrument the web browser. In our architecture, the browser is extended with a modified Web API Manager extension, which allows to capture calls to JavaScript methods and log information about these calls. The platform was used to perform measurements on a 10,000 websites. From the analysis of the data obtained by the measurement, we found that the most used APIs over measured websites are APIs specified in HTML and DOM standards, High Resolution Time API and Web Cryptography API. Within the APIs that were implemented in Mozilla Firefox after 2016, we identified the Intersection Observer API, Background Tasks API and Resize Observer API as the most frequently used.

To investigate the feasibility of improving performance for EcmaScript code in environments that restricts the usage of dynamic just in time compilers, an ahead of time EcmaScript to C compiler capable of compiling a substantial subset of the EcmaScript language has been constructed. The compiler recovers type information without customized type information by using the Cartesian Product Algorithm. While the compiler is not complete enough to be used in production it has shown to be capable of producing code that matches contemporary optimizing just in time compilers in terms of performance and substantially outperforms the interpreters currently used in restricted environments. In addition to constructing and benchmarking the compiler a survey was conducted to gauge if the selected subset of the language was acceptable for use by developers.

This thesis deals with introduction of Mozilla as a development platform. Thesis is divided into four parts. The first one consists of a theoretical introduction, which describes architecture, the most important technologies and motivation for usage of Mozilla as a development platform. The second part leads step by step threw making own project. The third part is dedicated to description of the example application Tester. Tester is an e-learning project designed for easier learning process with scope on vocabulary practise. In the conclusion of thesis, there is the evaluation of Mozilla platform based on practical experience.

The aim of this master's thesis is to design and implement JavaScript interpreter which is designed for purposes of avoiding obfuscation code of various types of computer viruses. This master's thesis also comprises a detailed view into the inner mechanism of the ECMAScript standard.

The goal of this investigation has been to answer the questions “Which graphs should be used to display a special type of information?”, “What information does a company need to know that a server has gone down?” and “How should the layout of the developed program look to be called easy to understand and nice to use?”. The investigation was helped by the use of user-interviews and information that was collected during meetings. Part of the work was also the development of a prototype of a so called “dashboard” where functions where tested. These tests were then used to find out if the information was showed in a suitable manner. The information gained from these earlier tests has then been compiled into a result which shows that it is important to use y-over time graphs to show information over time. Fraction based information such as pro- cents are best showed with a filling graph, such as the speedometer graph. The second question was easily answered with a simple questionnaire. The result of this questionnaire showed that it was important for companies to know how much of the servers resources was used and how much data that was sent and received. Regarding the last question, the only notable result was the fact that the UI of the prototype was to light. This resulted in a color change for the UI to the darker spectrum. / Målet med denna undersökning har varit att besvara frågorna ”vilka grafer kan användas för att visa en speciell typ av information?”,”vilken information be- höver ett företag veta för att fastslå att en server är nere?” samt ”hur ska det utvecklade systemet vara upplagt för att vara enkelt att förstå samt trevligt att använda?”. Undersökningen har utförts med hjälp av användarintervjuer samt information som insamlats under möten. Utöver denna information så har också en prototyp av en så kallad ”dashboard” skapats där grafer samt funktioner som föreslagits undersökts för att återge om informationen samt funktionerna på gränssnittet visas på ett bra sätt. Denna information har då sammanställts till ett resultat som visar att det är viktigt att återvisa information över tid som gra- fer samt procentuell information med hjälp av en fyllande graf, då kanske en hastighetsmätargraf. Den andra frågan svarades enkelt på med hjälp av ett frågeformulär. Detta gav då som resultat att det var viktigt att se resursanvänd- ning på servrarna samt hur mycket information som skickas och mottages. Det- ta implementerades sedan i systemet. I de tidigare nämnda intervjuerna fram- kom det också att det var bra om systemet inte var ljust färgat då detta gjorde så att användarna blev enkelt distraherade av gränssnittet. På grund av detta så ändrades alla färger mot det mörkare spektrumet.

<p>An IPTV Set-top box enables the possibility of doing much more than decodingtelevision content. Its Ethernet interface gives it the same possibilities to communicatewith the outside world as any network device. This enables a wide rangeof services from internet radio to acting as a digital media receiver in your homenetwork. These highly interactive services increase the demands for responsiveand visually attractive user interfaces.Due to the cost-sensitive market of IPTV STBs the preferred platform to developthe user interface is the HTML browser as it allows for fast developmenttimes and low costs. As a W3C standard it also offers high portability and hardwareabstraction making it easy to use more than one STB vendor. The cons ofHTML based GUIs are low performance and lacklustre graphics.This thesis aims to find out if SVG can be used to achieve rich, scalable and animatedgraphics with high performance and still keep the attractive characteristicsof HTML.To do this much effort was put into identifying the strenghts and weaknesses ofSVG. The lessons learned resulted in an SVG AJAX framework called TOIXSVGmaking it possible to develop SVG GUIs in the same manner as modern Rich InternetApplications, enabling component reuse to make sure development time scalespreferably with the scope and complexity of the user interface.
