Open Compliance Reference Tooling in a Linux system context

The tooling group (also part of the OpenChain Tooling Workgroup) works on open source solutions for automated Open Source Management and already came up with "Open Compliance Reference Tooling" representations for some typical use cases (Java, NPM, Python, etc.). Approaches for automated Open Source Compliance Management for Linux systems were already discussed too, but the challenges seem to be of a different nature.

The Open Source Way

An Illustration of Javascript Dependency Hell using left-pad

Marc Dumais (Ericsson AB)

In the JavaScript ecosystem, it's part of the culture to enthusiastically re-use existing packages made by others as part of one's own work, rather than reinventing the wheel. This means that, on average, an npm package has several production dependencies, as well as several build/test (dev-)dependencies. For a big application or a framework this can result in pulling a big number of direct dependencies, which in turn have their own dependencies, and so on, forming an unexpectedly deep and wide dependency tree, that someone has to manage (FOSS Compliance, security flaw management, ...)

Don’t Trust Software, Padlock Your Edge Hardware Instead

kathy giori (open source community)

Cyber attacks and huge ransomware payments are making headlines. The growing complexity of deployed edge software and the necessity to tie it into a plethora of back-office systems is causing IT professionals to lose sleep. Since it’s hard to say no to new software applications, our advice is to not trust it. Instead, lock down your hardware so your IT staff can boot out or patch misbehaving software at any moment.

Exploring Stateful Microservices in the Cloud Native World

Mary Grygleski (IBM)

How does one choose to architect a system that has a Microservice / REST API endpoints? There are many solutions out there. Some are better than others. Should state be held in a server side component, or externally? Generally we are told this is not a good practice for a Cloud Native system, when the 12-factor guidelines seem to be all about stateless containers, but is it?

Invoking Analysis Tools as Web Services from the Eclipse IDE

Jan Fiedor (Brno University of Technology)

Ondrej Vasicek (Brno University of Technology)

With the increasing complexity of projects, many users and teams rely on various kinds of analyses to check if their work (code, models, requirements, etc.) is correct. While various analyses are often performed as part of the CI/CD pipelines, many users would prefer to perform them before submitting (publishing) their work. Yet many analysis tools needs to be installed, configured, and started externally, which can be difficult for many users, especially when they are not proficient with the tools.

Sustainability in Software Engineering - Carbon Offsetting Explained

Martin Lippert (Pivotal Software, Inc now under VMWare-April 2020)

At last years EclipseCon Martin gave an introduction into the overall topic of sustainability in the context of software engineering. This talk dives deeper into one of the aspects: carbon offsetting. It is a widely used technique to deal with existing carbon emissions if they cannot be avoided upfront. And while this is generally seen as a good action towards making a positive impact to protect the climate, the devil is in the details.

Buttons hidden in plain sight

Bianca Wiesmayr (Johannes Kepler University Linz)

Alois Zoitl

Do you want to improve the user experience of your graphical modeling tool? Users are accustomed to a variety of utile features in textual editing that also benefit graphical modeling tools, such as efficient auto-completion, automated formatters, and immediate feedback on the software. As developers of graphical modeling tools, we strive to assist users in creating high-quality and scalable models. Over the last years, we experienced that improving the user interface of our modeling tool involves difficult trade-offs that need to be discussed within the project's community.

Conquering large scale visualization challenges with JavaFx and ELK

Amal Jose Vallavanthara (Robert Bosch Gmbh)

Syed Aoun Raza (Robert Bosch GmbH)

Rakesh Nidavani (Robert Bosch Engineering and Business Solutions Private Limited)

Harald Mackamul (Robert Bosch GmbH)

Working with large-scale automotive data models without a proper visualization support is quite cumbersome. There are a few frameworks which support handling of large dataset out of the box for example, Sirius, Klighd, and JavaFX. Another aspect is lay-outing the scenarios in a properly comprehensive manner. Previously, we had reported our experience of using Sirius framework in large-scale data.

Simulation and Validation of Smart Shared Parking Services using Eclipse Ecosystem

Muralikrishna Thulasi Raman (itemis AG)

Parking is a traditional vehicular hassle. From my personal experience, in major cities, vehicles are to be parked in a distant location when travelling to a destination. Considering the environment of the distant parking place where the vehicle is parked, the driver or owner might feel insecure about the safety of their vehicle. To overcome this, we modelled a parking model that considers distance between parking lot and destination and also revenue generated by the residential parking lot owners.

APP4MC.sim - Timing simulation of embedded systems

Harald Mackamul (Robert Bosch GmbH)

Sebastian Reiser (Robert Bosch GmbH)

An abstract, non-functional timing simulation supports the system architect in the step from the idea to the elaborated concept and immediately serves as an executable specification. The model elements for describing the software are limited to processor runtimes and access to hardware resources. Through this abstraction, the distribution of software in the system and dynamic effects from the scheduler behaviour can be evaluated quickly. For effective and early runtime analysis of AMALTHEA models, we have therefore extended the APP4MC ecosystem with the simulation framework APP4MC.sim.

Rapid Test-Driven Development for Eclipse plugins: Bndtools, continuous testing and the Facade pattern

Jeremy Krieg (Greek Orthodox Archdiocese of Australia - Greek Welfare Centre of SA)

Testing is an important aspect of any software project. For backend software and components, this will typically comprise of automated tests, but also in a UI application it will involve manual testing and interaction with the UI.

In spite of how important it is, testing is often a neglected area of development because of how inefficient it seems. In a large system, you can spend a lot of time waiting for the application-under-test to restart with your fresh changes so that you can test them. The result is simply that we don't test as often as we should.

The Theory Of Everything: Unifying for Data in Motion, Data at Rest and Computations

Angelo Corsaro (ADLINK Technology)

Julien Enoch (ADLINK Technology)

Olivier HECART (ADLINK Technology)

The idea of finding a theory of everything providing the minimal set of abstractions for dealing with data in motion, data at rest and computations, at any scale, has always fascinated and to some extent obsessed us. We have been working on this problem for years, refined our abstractions, evolved our sensibility, and deepened our understanding of the problem — after years of sweat, we think we have possibly found the answer.
