description: Documentation, archival and transmission of contemporary dance works and practices raises the question as to how and in what scope digitisation can already happen embedded in the creative process. To reach beyond performance as a seemingly tangible artwork, modes of digital capture must allow for embodied, intangible references and sub-processes to be put into context by practitioners and scholars. Bodies of work are thus being mapped to hyperlocal referential networks, discrete languages and ontological vector spaces. I present my work on mapping these networks and their unstructured artefacts through means of linked data and annotation as a "semantic glue" to facilitate navigation, inspection and manual as well as automated inference.

description: RCE (Remote Component Environment) ist eine verteilte Integrationsumgebung, die im DLR entwickelt und von Forschern innerhalb und außerhalb des DLR genutzt wird. RCE ermöglicht das Einbinden und Freigeben von Simulationswerkzeugen, die über ein Netzwerk gemeinsam genutzt und zu automatisierten Workflows kombiniert werden können. Ein typisches Anwendungsgebiet ist hierbei die multidisziplinäre Optimierung z.B. von Flugzeugentwürfen. RCE ist Open Source und wird in Forschungsprojekten in Zusammenarbeit mit Nutzern weiterentwickelt. In diesem Vortrag zeigen wir, wie wir RCE im Team entwickeln und welche besonderen Herausforderungen die Entwicklung einer Produktivsoftware im Forschungskontext mit sich bringt.

description: The promise of the super-computing industry has always been that pioneering bleeding-edge technology built for the hyperscale filters down to become mainstream so we all have exciting stories about how the phone in your pocket is as powerful as the world’s fastest machine from not-so-many years ago. Whilst this is (was?) true for hardware, there are very few scientists who’ll tell you that software ease of use or accessibility has moved in such leaps and bounds. Moreover, whilst collaboration with others around the globe brings a lot of benefits, other factors like data security and privacy that can frequently – and very suddenly – demand lots of attention. If we’re to keep our pace of scientific discovery going (or even accelerate it), our most pressing task in the computing community is to give working scientists access to the tools and techniques they need in a form that’s easy to use, secure for their data and scalable to the limits of their ideas – not limited by their laptop’s memory capacity. This means an inherently different approach to what has come before, not just business as usual with more bandwidth.

As a consequence the development of software becomes more and more the norm in research alongside the mere use of software. In an effort to obtain an overview of the current practice of research software development at DLR and to optimize our existing support activities for software developers at DLR, we conducted a DLR-wide survey on research software at the end of 2018.

description: AIRR-seq (Adaptive Immune Receptor Repertoire sequencing) data is a special subtype of genome sequencing data, which is assumed to be representative of an individual's immune status and therefore holds large promises for biomedical research. The AIRR Community was founded in 2015 with the goal to foster the exchange of AIRR-seq data by making it FAIR and available under free/open licenses. It is an international group that assembles researchers and practitioners from all disciplines involved in generating, processing and interpreting this data: Biology, informatics, data science, medicine and law. In this talk I will summarize the main lessons we learned in the process of establishing the community and setting and reaching its goals.

Clever designed data classes could mitigate this risk. We present the prototype of an R data class targeted at increasing the reliability of data processing. The aim is to have a data class that features built-in consistency checks and meta-data handlingwithout putting additional burden on the scientist. The current prototype keeps track of units and converts untis automatically, it prevents non-matching data from being combined, and it automatically generatesmeta-data during calculations allowing to inspect what kind of calculation has been performed on the data.

Doch ist mit der Veröffentlichung alleine noch nicht der nachhaltige Fortbestand einer Software garantiert.

description: With ediarum, the TELOTA group of the Berlin-Brandenburg Academy of Sciences and Humanities has been developing a working and publication environment for digital scholarly editions for several years. In contrast to similar projects, a bottom-up approach was chosen, i.e. the research environment was developed for the needs of individual scholarly editions projects. Due to the success of the research software, ediarum is used for more and more editions. This led to the change of the development model to a generic approach. The advantages and disadvantages of the development approaches and the organizational structure are discussed in the article.

This triggers cross-disciplinary exchange, the strength of which will be illustrated by presenting an ongoing project on linking metabolomic and genetic data. Computational analysis of genomes can predict biosynthetic gene clusters (BGCs) responsible for producing complex biochemical compounds, many of which are still unknown. Adapting machine-learning tools from different domains, we develop a novel method aiming to pinpoint causal links between predicted BGCs and yet unidentified compound signals detected in rich metabolite mixtures.

Research software communities are a great way to support a "grass roots" base of researchers and developers building software, helping them enhance their skills, network with peers and build new collaborations. In this talk I'll provide my perspective on the benefits of research software communities and look at examples of building a UK-based local, institutional community and a wider regional community. Through these examples, I'll look at challenges faced in starting and sustaining such communities and highlight some of the key benefits they can offer.

Expect this approach to yield unstable software with unsatisfactory performance and an unmaintainable code base. Get a few basics right, and everything will be so much clearer and easier: Strictly separate the GUI layer from the scientific core. Dare using global variables to hold session and GUI state. Cache computational results. Ensure that the display is always up to date. Provide an emergency interrupt button. Foresee multithreading. Log user actions. Use a replay engine during development and for testing. Plan for scripting.

Using the example of a search engine for linguistic annotations, we show which problems can occur when operating a search-based service with persistent IDs for queries and results and present possible solutions. Different components, such as the software, the domain-specific query language, and the web service, provide different guarantees and make different demands on downward compatibility. By migrating an existing PostgreSQL-based system to our own implementation, we gain important practical experience in the downward-compatible modernization of an existing system, which we will share in this talk.

Reproduzierbare Simulationsläufe auf verschiedenen Plattformen gestaltet sich ebenfalls schwierig, da alle Abhängigkeiten im Vorfeld ebenso reproduziert werden müssen. Um diese Schwierigkeiten zu umgehen und reproduzierbare Wissenschaft zu erleichtern, können Container-Technologien als leichtgewichtige Alternative zu Computer-Virtualisierung eingesetzt werden. Am Beispiel der FEM-Simulations-Software OpenGeoSys wird in diesem Vortrag gezeigt, wie Container-Technologien (Singularity und Docker) eingesetzt werden können, um eine komplexe wissenschaftliche Software zu konfigurieren und zu erstellen und um sie schlussendlich portabel auf verschiedensten System (auch im High-Performance-Computing-Bereich) einzusetzen.

This includes the simulation of processes on a large range of scales and of different Earth system components. To account for the different components, Earth System Models (ESM) are composed of submodels. In practice, these submodels are developed independently and bring their own scripts for downloading, compiling and execution. In order to bundle these various scripts in one tool, we developed the ESM-TOOLS software. The aim is to facilitate the work with different ESM and, therefore, to ease the work of the Earth system scientist. We will briefly explain the purpose of the ESM-TOOLS, and discuss our experiences during development and application by the users.

description: Writing tests for scientific computing software is very hard. The input space for programs can be infinite, therefore selecting "good" or "interesting" inputs is crucial. Time and computing resources to execute tests however are limited, but developers need timely responses to changes. Guidelines to implement tests under these, and likely more, constraints are not readily available in literature. This contribution tells the story of trying to move our Python library pyMOR to property based testing, simplifying the process of writing more meaningful tests with less code and balancing runtime versus impact. We also include a call to action for the community to jointly develop concrete guidelines for designing and implementing unit tests.

description: The efficient use of modern supercomputers has become one of the key challenges in computational science. For the numerical solution of time-dependent processes, time-parallel methods have opened new ways to overcome scaling limits. With the “parallel full approximation scheme in space and time” (PFASST), multiple time-steps can be integrated simultaneously. Since its use within an existing application code is not straightforward and the potential gain is typically uncertain, we will present in this talk our Python prototyping framework pySDC. It allows to rapidly test new ideas and to implement first toy problems more easily. We will also discuss the transition from pySDC to application-specific implementations.

description: Many scientific applications require computation resources based on dynamically changing requirements. The H2020 COLA (project-cola.eu) set out to solve this with a generic framework (MiCADO) to support automated scalability of applications deployed to the cloud. MiCADO is open-source, cloud agnostic and uses widely applied technologies - Kubernetes, Occopus and Prometheus - to scale virtual machines and containers in the cloud. MiCADO has been tested on a range of small to large-scale research activities that saw simulations and other multi-job experiments queued, executed and scaled in containers on different public and private clouds. The talk will focus on MiCADO, its architecture, characteristics, and its benefits to the RSE community

Laser fundamentals I: Light amplifier

uk: Фізика, Астрономія

uk: Математика, природничі науки

description: This resource contains demonstrations used to illustrate the theory and applications of lasers and optics. A detailed listing of the topics can be found below. Lasers today are being used in an ever-increasing number of applications. In fact, there is hardly a field that has not been touched by the laser. Lasers are playing key roles in the home, office, hospital, factory, outdoors, and theater, as well as in the laboratory. To learn about lasers and related optics, one usually takes a course or two, or acquires the necessary information from books and journal articles. To make this learning more vivid and more exciting, and, one hopes, more understandable, one needs to see some of the basic phenomena involved. To fill this need, Professor Ezekiel has videotaped 48 demonstrations that illustrate most of the fundamental phenomena relating to lasers and physical optics. By using split-screen inserts and a wide range of video-recording capabilities, it is possible to show real-time effects in lasers and optics with the simultaneous manipulation of the components that cause these effects. In this way, one can see effects in close up that would be difficult, if not impossible, to display in front of an audience or in the classroom. These video demonstrations are designed for: The individual student of lasers and optics who wants to observe the various phenomena covered in theoretical treatments in courses, books, and technical papers. The Instructor in lasers and optics in a company, university, college, or high school who wants to illustrate, in class, many of the fundamental phenomena in optics and lasers.

description: The Free Software movement has achieved a lot. When you are running free software yourself you enjoy all the benefits of free software, the freedoms to use, study, share, and improve the software. You are in control of your computing. When using web services the situation is different. Even when the service provider runs free software, it doesn't mean that as a user you have the same freedoms. What about privacy? How does the freedom of one user affect the freedom of another user? Who owns the data? There are a lot of questions like this. This keynote will explore how a definition of freedom for web services could look like. It's the beginning of a journey, which needs involvement of creators and operators of web services as well as the community at large. At the end we will hopefully have a definition how to guarantee people using web services the same freedom they have when running free software themselves. Cornelius is a long term FOSS enthusiast and contributor, has been on the board of KDE e.V. for nine years, half of that as its president, and works as an engineering manager for SUSE Linux."

Impersonation: OC accesses the users data, "as" the user. It therefore obtains a Kerberos ticket and accesses as NFSv4-Client. This enables Sync usage, but ... 2. ... in order to pick up changes, scanning has to work reliable and quick, see e.g. bug [#11797](https://github.com/owncloud/core/issues/11797). 3. CRUDS vs. ACLs: To enable sharing of File-Service data, ACLs have to be automatically set, modeling OCs CRUDS permissions. 4. Transparency: The further goal is to enable all usage patterns (access, sync, share, configure share, ...) over all protocols.

The users ownCloud directory is accessible to the user on any server which has their home directories mounted (basically all of them) from the command line. I'm definitely not a programmer, rather I am a SysAdmin. This was my first attempt at using python and I am sure it could be improved. I am happy to share my process and see what ideas it sparks.

description: We will talk about DAVdroid as well as its underlying library dav4android and how it can be used in other projects. DAVdroid is an open source CalDAV/CardDAV synchronization app for Android. Its underlying library dav4android is also developed by us. We've decided to now publish this lib under MPL, thus making it possible to be used in other (commercial) products as well. It opens the way for many developers to use WebDAV. We will give a short view on the internals of this library and discuss how collaboration could work.
