  • An Overview of Platforms for Cloud Based Development G
    Fylaktopoulos et al. SpringerPlus (2016) 5:38 DOI 10.1186/s40064-016-1688-5 REVIEW Open Access An overview of platforms for cloud based development G. Fylaktopoulos1, G. Goumas2, M. Skolarikis1, A. Sotiropoulos3 and I. Maglogiannis4* Abstract This paper provides an overview of the state of the art technologies for software development in cloud environments. The surveyed systems cover the whole spectrum of cloud-based development including integrated programming environments, code repositories, software modeling, composition and documentation tools, and application man- agement and orchestration. In this work we evaluate the existing cloud development ecosystem based on a wide number of characteristics like applicability (e.g. programming and database technologies supported), productiv- ity enhancement (e.g. editor capabilities, debugging tools), support for collaboration (e.g. repository functionality, version control) and post-development application hosting and we compare the surveyed systems. The conducted survey proves that software engineering in the cloud era has made its initial steps showing potential to provide con- crete implementation and execution environments for cloud-based applications. However, a number of important challenges need to be addressed for this approach to be viable. These challenges are discussed in the article, while a conclusion is drawn that although several steps have been made, a compact and reliable solution does not yet exist. Keywords: Cloud computing, Integrated Development Environment (IDE), Code repositories, Software modeling, Orchestration tools Background application side, large families of applications including Within the past few years, cloud computing has emerged desktop, business, entertainment (Simmhan et al. 2010; as a dominant computing model in IT infrastructures, Schmidt 2012; Hobfeld et al.

  • Programming in Java with Eclipse
    INFO0062 - Object-Oriented Programming Programming in Java with Eclipse Jean-François Grailet University of Liège Faculty of Applied Sciences Academic Year 2018 - 2019 Installation of Java and Eclipse Creating a project in Eclipse Program arguments in Eclipse About Eclipse Eclipse is an Integrated Development Environment. It’s a program specifically designed for software development. It provides • a code editor (with code coloration) • compilation and debugging tools • project management, auto-completion, etc. For those who followed INFO2009 or INFO0946, it’s like Code::Blocks. Eclipse is a very simple solution to program in Java under Windows. • macOS/Linux users can use it too, but using java/javac is a simpler approach. • Eclipse can however be arguably more practical for large-scale projects. 1 / 17 Installation of Java and Eclipse Installation of Java and Eclipse Creating a project in Eclipse Program arguments in Eclipse How to install Eclipse You will need to: • install Java on your computer • install Eclipse itself To install Java SE (Standard Edition), you can • Windows/macOS: download it on Oracle’s website. • Linux: install it via an online repository. N.B.: Java’s lattest versions are 64-bit only. • I.e., only compatible with a device that has a 64-bit hardware. Hopefully, most computers (including laptops) are 64-bit nowadays. If your device is quite old, it might be worth to double check it. • N.B.: quite old here means more than several years (e.g. 5). 2 / 17 Installation of Java and Eclipse Creating a project in Eclipse Program arguments in Eclipse How to install Java SE Windows/macOS • Download and install Java SE 11 • 32-bit Windows: download and install Java SE Development Kit 8u201 for x86 Linux • You can use an online repository to download and install Java SE 11 • 32-bit devices: prefer using your OS’ default repositories.

  • A Strategy for Addressing the Needs of Advanced Scientific Computing Using Eclipse As a Parallel Tools Platform
    A Strategy for Addressing the Needs of Advanced Scientific Computing Using Eclipse as a Parallel Tools Platform Gregory R. Watson Craig E. Rasmussen Los Alamos National Laboratory P.O. Box 1663, MS B287 Los Alamos, NM 87545 December 2005 LA-UR-05-9114 ABSTRACT If parallel computer systems are to achieve the kinds of productivity improvements necessary to meet the needs of high productivity computing systems (HPCS), then a radical change will be required in how tools are developed for programmers and users of these systems. The number and complexity of tools is making it difficult for developers to access and use the tools effectively, and the lack of a common tool infrastructure significantly complicates tool development efforts. The rapid pace of change means that developing and maintaining the kinds of tools that will be needed to effectively utilize the capacity of future advanced computer systems is an increasingly onerous task. This paper proposes a strategy that will lead directly to productivity and quality improvements in the development and use of parallel applications, and that will provide a framework to guide and foster future tool development. This strategy is based on using the Eclipse platform to form the foundation of an integrated environment for parallel application development. The intention is not just to produce another set of tools, however, but rather to use Eclipse as both a focal point for tool development, and as a platform for producing highly integrated tools that are needed to meet the future needs of the HPC community. A Strategy for Addressing the Needs of Advanced Scientific Computing Using Eclipse as a Parallel Tools Platform 1 1 INTRODUCTION As high productivity computing systems (HPCS) are developed to meet the demands and computational challenges facing advanced scientific research, it is becoming increasingly apparent that existing software infrastructure and tools will need to be substantially improved in order to achieve the goal of sustained performance on terascale machines [17].

  • Top Productivity Tips for Using Eclipse for Embedded C/C++ Developers
    Top Productivity Tips for Using Eclipse for Embedded C/C++ Developers Garry Bleasdale, QNX Software Systems, [email protected] Andy Gryc, QNX Software Systems, [email protected] Introduction This paper presents a selection of Eclipse IDE tips and tricks gathered from: the QNX® development community: our engineers, techies and trainers Foundry27, the QNX Community Portal for open development, where we have an Eclipse IDE forum Eclipse.org forums public web sites and blogs that offer Eclipse-related expertise The 27 tips described in this paper are the tips that we received from these sources and identified as most interesting and useful to developers. We present them here with the hope that they will help make you more productive when you use the Eclipse IDE. About Eclipse A modern embedded system may employ hundreds of software tasks, all of them sharing system resources and interacting in complex ways. This complexity can undermine reliability, for the simple reason that the more code a system contains, the greater the probability that coding errors will make their way into the field. (By some estimates, a million lines of code will ship with at least 1000 bugs, even if the code is methodically developed and tested.) Coding errors can also compromise security, since they often serve as entry points for malicious hackers. No amount of testing can fully eliminate these bugs and security holes, as no test suite can anticipate every scenario that a complex software system may encounter. Consequently, system designers and software developers must adopt a “mission-critical mindset” and employ software architectures that can contain software errors and recover from them quickly.
