It provides a machine abstraction and hardware-agnostic instruction sets, where a high-level programming language can target the compilation to the Wasm instead of specific hardware architecture. The JavaScript engine implements the Wasm specification and recompiles the Wasm instruction to the target machine instruction where the program is executed. Technically, Wasm is similar to a popular virtual machine bytecode, such as Java Virtual Machine (JVM) or Microsoft Intermediate Language (MSIL). -

We combine speech recognition, improv chatbots and language translation tools to enable improvisers to com- municate with each other while being understood—or comically misunderstood—by multilingual audiences. We describe the technology underlying Rosetta Code, detailing the speech recognition, machine translation, text generation and text-to-speech subsystems. We then describe scene structures that feature the system in performances in multilingual shows (9 languages).

Diploma/Master/Student Thesis —
Institute of Architecture of Application Systems University of Stuttgart Universitätsstraße 38 D-70569 Stuttgart Evaluating the Profitability of the MediaWiki Application under different Cloud Distribution Scenarios María Elena Alonso Mencía Course of Study: Computer Science Examiner: Prof. Dr. Dr. h. c. Frank Leymann Supervisor: Dipl.-Inf. Santiago Gómez Sáez Commenced: April 7, 2016 Completed: September 29, 2016 CR-Classification: C.2.4, C.4, G.1.2 Abstract Cloud computing has gained popularity over the last years, causing a significant increase of available cloud offerings among providers. Therefore, this wide spectrum of options has led to an increment of possibilities for distributing applications in the cloud, by means of selecting specialized services to host each application component. Nevertheless, it also implies the need of finding the optimal solution depending on its purpose, usually based on future economical profitability. Nowadays, instead of considering an application as a whole when deploying it in the cloud, e.g. deploying whole application stack in a virtual machine, investigations focus on how to distribute the application components in heterogeneous cloud environments. Consequently, users have an even higher range of options and should carefully choose good decision criterion, going further than only considering the direct cost for the needed cloud instances. Some challenges are deriving a revenue model - as they tend to be application specific - and customizing the evaluation of different migration configurations of a real application with authentic data metrics. In this sense, this document uses utility analysis as it includes a non-directly countable element, preferences, and allows basing the decision on a trade-off taking into account other aspects which have an influence on the final performance such as users satisfaction or cloud instance availability under different deployment topologies. -
L15N Server Side Programming
Lecture #15: Server-Side Programming CS106E, Young In this lecture, we learn about programming on the server. We consider several different models of how a program can generate a webpage. We see that there are many different languages and frameworks that can be used on the server-side. The tools used on both client-side and server-side are sometimes referred to as the Development Stack. Finally we consider two different data formats XML and JSON which are used in web programming. Front End and Back End Engineering - We will often divide the components of a webserver into two distinct parts – front-end and back- end. o You may hear people talk about being a front-end developer or a back-end developer or talk about their web applications front-end or back-end. - The Front End consists of the HTML, CSS, and any Client-Side Programs (i.e., JavaScript) - The Back End consists of Server-Side Programs and the Database o Back-end engineers would also work on server-side configuration, load balancing, content delivery network (CDN) and server infrastructure issues. Basic Models of Server-Side Programming - There are two traditional methods for creating a webpage server-side. HTML with Server-Side Code Added ▪ With this approach a webpage on the server-side looks almost like a tradition HTML file, except in a few places, we ask the server to insert new information based on code executed on the server. ▪ Here is a sample using the server-side language PHP. <!DOCTYPE html> <html> <head> <meta charset="UTF-8" /> <title>Time of Day</title> </head> <body> <h1>Time of Day</h1> <?php $now = new DateTime(); echo $now->format("h:i:sA"); ?> </body> </html> ▪ Notice how this looks almost exactly like HTML, except for the section enclosed within the <?php and ?>. -

It is written mostly in Java and can be used to develop applications in Java and, by means of various plug-ins, other programming languages including Ada, C, C++, COBOL, Perl, PHP, Python, Ruby (including Ruby on Rails framework), Scala, Clojure, and Scheme. The IDE is often called Eclipse ADT for Ada, Eclipse CDT for C/C++, Eclipse JDT for Java, and Eclipse PDT for PHP. The initial codebase originated from VisualAge.[2] In its default form it is meant for Java developers, consisting of the Java Development Tools (JDT). Users can extend its abilities by installing plug-ins written for the Eclipse software framework, such as development toolkits for other programming languages, and can write and contribute their own plug-in modules. Released under the terms of the Eclipse Public License, Eclipse is free and open source software. It was one of the first IDEs to run under GNU Classpath and it runs without issues under IcedTea. Eclipse (software) 2 Architecture Eclipse employs plug-ins in order to provide all of its functionality on top of (and including) the runtime system, in contrast to some other applications where functionality is typically hard coded. -

These are extensions of the Tcl interpreters (tclsh, wish) which have been extended to commands for finite element analysis: 1. Modeling – create nodes, elements, loads and constraints 2. Analysis – specify the analysis procedure. 3. Output specification – specify what it is you want to monitor during the analysis. Being interpreters means that the files you create and submit to the OpenSees interpreters are not input files. You are creating and submitting PROGRAMS. What is Tcl? • Tcl is a dynamic programming language. • It is a string based command language . • Variables and variable substitution • Expression evaluation • Basic control structures (if , while , for , foreach) • Procedures • File manipulation • Sourcing other files . -
