In the recent past the monitor technology has changed dramatically. There is a tremendous decrease in pixel size which resulted in high dpi monitors. The operating systems are designed with the assumption we have 72 dpi for Mac and 96 dpi for Windows and unix. Before the advent of "Retina" display this used to be the case. But with Retina displays the dpi started increasing. Now the application looks quite small on high dpi monitors to the naked eye. As the dpi increases the smaller the application looks. This presentation covers the challenges faced in resolving this problem.

 
 

Outline/structure of the Session

This presentation will cover

  • The challenges encountered (Explaining the problem area)
  • Possible solutions and support from OS
  • How the common approach is arrived at
  • What are the new APIs introduced in Eclipse
  • How scaling is done in case higher resolution images are not available/or for the existing applications which are not dpi aware

Learning Outcome

  • Gain understanding of the Challenges and Solutions w.r.t. High DPI monitors.

Target Audience

Eclipse UI developers

Requirements

For the presentation it would be better if we can get a 4K projector. This will help in demonstrating the exact problem live.

If 4K monitor/projector is not available we can demonstrate using screenshots.

        Thanks Sarvan. Responsive desktop-application in a way. Post this change in Eclipse platform code, would there be a need for SWT consumers to make any more changes / api-calls for Eclipse/RCP applications?

          Yes. Pure SWT consumers will require to make changes for images if they need sharper images in the UI. if you are Jface consumer you need to create @2x images and store them at the same location as the original images.

    Node and Javscript have already gained massive popularity as a impressive web /cloud development platform and programming language respectively. Yet, it has certain perceived challenges and improvement opportunities - with respect to i) Enterprise grade deployment infrastructure, ii) Problem determination capabilities, iii) Elevation to all types of workload scenarios. In addition, JavaScript as a language has peculiarities from traditional declarative and object oriented languages, which makes it error prone, when used to develop large and complex software modules.

    The insight we gained by working closely within Node community and customers, suggests a workshop with the following theme will be of good benefit to the node developers:

    a. Introduction to Node programming

    b. Introduction, usage and main features of most common node subsystem modules: express, request, async

    c. Introduction, usage and main features of most common enterprise features: loopback, cluster, pm2

    d. Introduction, usage and main features of most common monitoring and debugging frameworks, techniques: google chrome dev tools, appmetrics, idde, heapdump

    e. Any other items which are relevant to node such as programming best practises etc.

    f. An Node clinic for open questions, discussions and live debugging.

    Java is the language of choice in enterprises. Many of the large software systems are built using Java. The key reason for Java being language of choice was the tool support, robust JVM, statically typed language and modularity. Modularity is one of the key aspects of the design. Eclipse (built on Java) is the wonderful example of a modular software system based on OSGi specification (Equinox). Project Jigsaw which is umbrella project is aimed to design and develop a standard module system which is compatible with OSGi. Brining modularity within the platform will add many improvement and will also provide the ability to run it down to small devices. Jigsaw has been one of the major features of JDK 9.0. The talk will cover details of project Jigsaw. 

    Java is mostly used presently at server side. Improvement in the server side processing and ability to evolve with the new specification and protocol would boost the performance. HTTP/2 which is the latest specification makes use of streams. Java 9 brings native support of HTTP/2.

    Java has been a programming language of choice for many years in academia, till the less verbosity, better interpreters and tools for JavaScript, Python evolved. The language evolved a bit 2014 with the introduction of Lambda in Java 8, which provided less verbosity. Still the absence of Read-Eva-Print Loop (REPL) moved the academia to embrace python as the language of choice for teaching problem solving to the students. Java 9 is bringing jShell which provides REPL functionality in Java 9.

    The Eclipse IDE provides a lot of powerful features and capabilities. With so much functionality at your disposal, many users don't use the full potential of the IDE. To be most productive, mastering your IDE is as important as mastering your source code.

    In this talk, I will unleash many invaluable tips and tricks that will allow you to better use the Eclipse IDE and make you more productive in your routine development tasks.

    Once you know how to leverage these powerful features of Eclipse to the fullest, you are going to enjoy working with Eclipse more than you could ever expect.

    I will cover various areas from efficiently organizing your workspace content to navigating, coding and debugging in Eclipse, and provide you a glimpse of some cool new Eclipse features.

    With Java 8 out the door, it is an exciting time to be a Java developer. The new constructs in Java 8 look nice but may not be so intuitive for developers. This is where Eclipse helps you to become more productive while writing and understanding programs with Java 8 constructs. I will show you how to make your experience with Java 8 more convenient and pleasant by using some new tooling features provided by Eclipse as part of its Java 8 support.

    I will also highlight useful tools like the AST and Java Element views, plug-in spies etc. that make working with Eclipse more effective.

    During this talk, you will have many "Ah, I didn't know Eclipse can do that!" moments. Some of the examples include:

    • Determining who last modified a line of code and when
    • Popping up an in-place outline of the element at cursor position
    • Bookmarks
    • Split editors
    • Grouping and sharing breakpoints
    • Print-points
    • Smartly stepping into a single method within a series of chained or nested method calls while using Java debugger
    • Identifying and navigating to the functional method from lambda expressions and method references

    Come and learn about the best Eclipse IDE capabilities that you might not be knowing yet. There will be something new for everybody.

    Eclipse committers have to watch the releng mailing list for build related emails, check every build for any test failures in their component, and analyse/report the failures if any so that further action can be taken. All this monitoring is really a monotonous task fit for an app - and that was how this app was born. The application periodically fetches available test results from hudson, and notifies registered users via email/push notifications. Users can register for email notifications by signing in with their google account and for push notifications via the android app. This is a good demonstration of how eclipse with its extensible framework and related tooling make it really straight forward to build, test and deploy applications to a cloud. This talk outlines the various tools used for the development of this application and gives a first hand account of using eclipse and related tools for cloud application development using a live application

    Have you ever wondered how the results automatically appear in the website? This talk will take you through this journey from the code to the results –the multi-stage, multi-tech release engineering process internals.

    There two different streams producing three different regular builds ( not taking into account the special P and Y) with the final bits running four different platforms making it a gruesome 32 hour journey optimized by parallelization. This process has four pipelined stages, with each stage driven by separate owners – one of them being Maven-Tycho configuration and the rest being a combination of shell Scripts, Ant, Junit in sync with multiple Hudson servers (HIPP).

    To give a peek into the stages : The first stage has private as well as publicly visible parts, using two stage cloning with bare bones and normal git repos owned by Scripts. Second Stage, owned by Maven-Tycho, is responsible for three maven-tycho builds. This output feeds into the next phase, owned by shell-scripts, which does a few things resulting in a transient pseudo-private download zone which again feeds into the last stage owned by Hudson-Ant-Junit Config and is responsible for actual firing of the tests in multiple platforms. Finally you have the publicly viewable html based downloads and results.

    Eclipse IDE is ubiquitous and the IDE of choice for application development no matter whether you are developing in Java/JEE or Python or Ruby or PHP - Eclipse IDE has a flavour that suits your taste. In recent times, the landscape of applications have undergone a significant change. More and more applications are developed by composing services and are deployed on specialized "Cloud" environments known as "Platform as a Service" - PaaS for short. 

    In this talk, we take a look at the various tools available in Eclipse Open Source ecosystem for developing applications for the cloud environment. We will traverse the journey of an app from conception to deployment. We will cover an online store application as an example. This talk will cover the tools that are best suited for each phase of the application development life-cycle - planning, work break down, coding, building and deployment. The tools include Eclipse Orion, Eclipse Tools for Cloud Foundry, Eclipse Tools for Bluemix, GitHub. We will also look at enabling continuous deployment using this tool set - practicing DevOps in true sense.

    This talk will explain the secret of the success of the Eclipse Platform team. The Eclipse Way is an agile software development process that we started right at the beginning when we started to develop Eclipse back in 1999. It was and is used by the Eclipse Platform team and got continuously improved over time. During the session you will hear about all our practices, like milestones, early and iterative planning, continuous integration and the endgame. I will also reveal some of the history behind the Eclipse top-level project.

    Java 9 introduces a major enhancement for modularity that helps define modules - The modular structure brings out a new paradigm shift in the way the programmer would program. From the perspective of JDT and its friends, this change means a relook at the existing concepts - starting from Java Model, through other core pillars of JDT. With the inputs from the EclipseConNA 2016, the JDT core is undergoing a change to incorporate these change both conceptually and at the core implementation level. In this talk, we will provide a brief introduction to the Java 9,  especially to those parts which affect JDT, we would also "redefine" some of the concepts in the Java Model, and then we will talk about the challenges faced and the solutions provided in JDT as a whole for Java 9.
