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). -

Ousterhout Sun Microsystems Laboratories Scripting: Higher- Cybersquare Level Programming for the 21st Century Increases in computer speed and changes in the application mix are making scripting languages more and more important for the applications of the future. Scripting languages differ from system programming languages in that they are designed for “gluing” applications together. They use typeless approaches to achieve a higher level of programming and more rapid application development than system programming languages. or the past 15 years, a fundamental change has been ated with system programming languages and glued Foccurring in the way people write computer programs. together with scripting languages.

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. -

Comparing Common Programming Languages to Parse Big XML File in Terms of Executing Time, Memory Usage, CPU Consumption and Line Number on Two Platforms
European Scientific Journal September 2016 edition vol.12, No.27 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431 Comparing Common Programming Languages to Parse Big XML File in Terms of Executing Time, Memory Usage, CPU Consumption and Line Number on Two Platforms Ahmed Mahdee Abdo Sardar Hasan Alali Computer Science department, Zakho University, Kurdistan, Iraq doi: 10.19044/esj.2016.v12n27p325 URL:http://dx.doi.org/10.19044/esj.2016.v12n27p325 Abstract XML files are used widely to save the information especially in the field of bioinformatics about the whole genome. There are many programming languages and modules used to parse XML files in different platforms such as Linux, Macintosh and Windows. The aim of this report is to reveal and determine which common programming language to use and on which platform is better to parse XML files in terms of memory usage, CPU time consumption and executing time. Keywords: XML, memory usage, CPU consumption and executing time. Introduction As many kinds of methods such as next generation technologies are used to sequence the whole genome, enormous amount of date became available. These dates are usually saved as text files. Extensible Markup Language (XML) files are kind of text files which are used to save much information about the whole genome.XML is a flexible text-based language that was developed by Standard Generalized Markup Language (SGML) to represent the information on the web server. XML is a document that represents the data as a structure which involves tags or entities and elements that are subset of these entities. Each element contains one or more attributes that define the method to process these elements. -
The Python Programming Language and Its Capabilities in the Gis Environment
THE PYTHON PROGRAMMING LANGUAGE AND ITS CAPABILITIES IN THE GIS ENVIRONMENT Katarzyna Szczepankowska mgr inż. Department of Real Estate Management and Regional Development University of Warmia and Mazury in Olsztyn Olsztyn, Poland e-mail: [email protected] Krzysztof Pawliczuk mgr inż. The Office of Student Systems Services University of Warmia and Mazury in Olsztyn Olsztyn, Poland e-mail: [email protected] Sabina Źróbek Department of Real Estate Management and Regional Development University of Warmia and Mazury in Olsztyn Olsztyn, Poland e-mail: [email protected] Abstract The first chapter of this paper reviews the most popular programming languages, including Java, PHP, Python, C# and C++, and describes their characteristic features. Chapter discusses the capabilities, technical features and advantages of Python which is quickly taking the lead as one of the most popular programming languages in the world. The authors emphasize Python's key strengths, including high efficiency, easy implementation of new functions, code readability, easy upgrade and its open source nature. The third chapter presents Python scripting options in the GIS environment and its popularity with major technology developers, among them Google, YouTube, Nokia and NASA. The last chapter discusses the rapid increase in Python's popularity and discusses its most recent applications, including in ESRI software and computer games. The extensive capabilities of Python make it suitable for developing various types of interactive maps. Key words: Programming language, Python, GIS, interactive map. 1. History of programming languages The history of computing machines dates back to the 20th century, but the breakthrough event in digital electronics was the invention of the transistor, the key component of various electronic systems.
