description: It can be argued that the Lin-Dadarlat-Eilers stable uniqueness theorem is one of the main driving forces behind several recent landmark results related to the classification program for nuclear C*-algebras. In a nutshell, the theorem strengthens the Cuntz picture of bivariant K-theory, and translates a KK-theoretic assumption into a rather strong statement involving (stable) asymptotic unitary equivalence of *-homomorphisms, which becomes immensely useful for extracting the role of K-theory in classification. In this talk I will present a generalization of the stable uniqueness theorem to the setting of C*-dynamical systems over a given locally compact group. I will also explain why this should be expected to be important in the context of classifying C*-dynamics up to cocycle conjugacy.

description: IoT changed deeply the value chain. End users of consumer devices aim to havean instant gratification which is based on data/metrics produced by theobject. At the end, IoT makers have to execute an epic split: Build the actualdevice (mechanical and electronics), Be over the top in firmware developmentin order to be secured Design services based on the object data. Surroundingall that is a hard job for a product team. In such a context Open SourceSoftware constitutes basic building blocks of IoT devices. Data produced bysmart devices are often time series, storing them is not the challenge, manygood open source solutions exists (OpenTSDB, Influx..) but developingalgorithms based on your data is difficult. It can become a nightmare if youhave to think about scalability. Warp10 is a 3 years old open source platformdesigned for collect, store and manipulate sensor data with WarpScript, alanguage dedicated to time series analysis. WarpScript works natively on timesseries stored into Warp 10 (based on either levelDB or HBase) but can beconnected to any data source. When you manipulate sensor data, you must dealwith privacy. Security and privacy have also been addressed by Warp 10 sinceits very inception, this includes fine grain access control mechanisms,encryption capabilities and throttling management. Warp10 plateform can beintegrated into an open ecosystem likes Storm, Flink, or also Apache Pig withone cornerstone, the capatibility of manipulate time series with WarpScript. The Warp 10 Platform is designed to collect, store and manipulate sensor data.Sensor data are ingested as sequences of measurements (also called timeseries). The Warp 10 Platform offers the possibility for each measurement toalso have spatial metadata specifying the geographic coordinates and/or theelevation of the sensor at the time of the reading. Those augmentedmeasurements form what we call Geo Time Series. The first differentiating factor of Warp 10 is that both space (location) andtime are considered first class citizens. Working with Geo Time Series allowsyou to have geo-located readings without having to use four separate seriesand having to keep track of the reading context. Complex searches like “find all the sensors active during last Monday in theperimeter delimited by this geo-fencing polygon” can be done without involvingexpensive joins between separate time series for the same source. We created WarpScript, an extensible stack oriented programming language whichoffers more than 700 functions and several high level frameworks to ease andspeed your data analysis. Simply create scripts containing your data analysiscode and submit them to the platform, they will execute close to where thedata resides and you will get the result of that analysis as a JSON objectthat you can integrate into your application. The WarpScript approach is another differentiating factor of Warp 10.Traditional time series platforms offer few manipulation options, usually onlyproviding a SQL like query language which cannot express complex analysis, orproviding a reduced set of aggregation functions. These approaches force youto produce more code on the client side thus increasing your development timeand leading to massive transfers of unprocessed data from the platform to yourapplications. Our approach lets you focus on your business use cases,simplifying IoT and sensor data applications by taking care of a larger chunkof the data analysis in a very efficient way.

description: In this talk we will step back from the generality of multidimensional shifts of finite type and focus on two specific classes: The space of graph homomorphisms from Zd to a fixed connected undirected graph and the space of tilings of Zd by rectangular shapes. While these classes cover fairly well-studied examples like the space of proper 3-colourings and domino tilings, a lot still remains to be understood. We will discuss some recent results about these shift spaces and try to pinpoint the difficulties which arise in their investigation.

Tree shift entropy

description: In joint work with Ibrahim Salama, we study the complexity function pτ(n) of a labeled tree or tree shift, which counts as a function of n the number of different labelings of a shape of size n. We give a definition of entropy, prove that the limit in the definition exists, and that the limit is the infimum. For tree shifts determined by adjacency constraints a version of Pavlov's strip technique proves strict inequality with dimension and provides an efficient approximation method. Attractive questions concern equilibrium measures and relations with other kinds of entropy.

description: On this panel, we will discuss the extent to which the use of Free Software and open hardware can be used in the public health sector. Software and hardware can help to solve global problems together. The wheel does not always have to be reinvented and through cooperation common innovation can succeed. The Corona crisis has clearly shown us that we also need to work together in the area of software and hardware. Hackathons were held in various countries, for example, to find software solutions to counter this crisis. The development of tracing apps or solutions for hospitals and health authorities has also shown that Free Software can help many people and that isolated solutions are counterproductive. In the panel we want to discuss what lessons we can learn from the crisis and how Free Software and Open Hardware must be used in the future.

Give open source a (tax) break

uk: Комп'ютерні науки

description: Financing open source using tax breaks on donations made to endowment funds or general interest associations is a construct available in France and a viable alternative to R&D expenditures for sponsoring open source projects. We will present several initiatives from the Libre Endowment Fund ("Fonds de Dotation du Libre" in French) - from financing feature development of open source software to releasing a 4G/5G base station as open source hardware or supporting litigation against the French government's decision to host Health Data on Microsoft servers. The recently published FOSS contributor report showed that 48.7% of contributors were paid for their contributions by their employer with only 2.95% being paid by a third party. So even today as (open source) software continues to eat the world, almost half of all projects lack the financial base for ensuring their respective software's long-term existence. To finance the long term maintenance of its open source software stack, Nexedi has created the Libre Endowment Fund ("Fonds de Dotation du Libre" or FDL in French). It is a French endowment fund which complies with strict auditing procedures. With this status, French Law permits corporations and individuals to donate to the FDL and claim back up to 60% from future income taxes (65% for individuals). Rather than investing directly in the maintenance or continuous development of own or third party solutions, Nexedi and other companies (ex. Amarisoft) can pool donations which then support the maintenance or development of open source software, open source hardware or open services. FDL also benefits from a scientific board of advisors which include three developers of open source software (Jean-Paul Smets, Stéfane Fermigier, Gaël Varoquaux) who also hold a PhD in computer science or mathematics. This scientific board follows the same procedures as governement sponsored RTD projects and thus also contributes to the juridical safety of FDL.

description: Router Freedom is a net neutrality principle that Internet Access Providers (IAPs) must not the limit the users' right to choose their own routers and modems to connect to the Internet protected in Europe since 2015. However, new rules on EU has created challenges router freedom, given that IAPs will be able to limit the right based on "objective technological necessity". The talk will go through the historical aspects and future developments in Europe. Net neutrality is the principle that Internet Access Providers (IAPs) must treat all Internet communications equally, and not discriminate or charge differently based on user, content, website, platform, application and type of access equipment. The FSFE has been involved with net neutrality advocacy in Europe since 2013, achieving positive results in Germany with a law securing end-users the right of free choice of routers and modems. In the context of the reform of European telecommunications law, EU Member States must implement in their national jurisdiction the European Electronic Communications Code (Directive (EU) 2018/1972), which brings new rules on router freedom, allowing IAPs to limit the rights of users if they can determine an "objective technological necessity" for imposing their routers and modems on consumers. The talk will go through the historical developments in the last two years in Europe to present an overview on the positions on the debate in regards to router freedom and the consequences for Free Software. As a take away, the talk will propose the discussion around the main principles of net neutrality and freedom of terminal equipment within the EU legal framework.

description: This proposed talk will present how Postgres could seamlessly and significantly benefit from replacing normal solid-state drives (SSDs) with emerging computational storage drives (CSDs). Aligned with the grand trends towards heterogeneous and near-data computing, computational storage has gained tremendous momentum and led to an on-going industry-wide effort on expanding the NVMe standard to support CSD. The first generation CSD products have built-in transparent compression, which can be deployed into existing computing infrastructure without any changes to the OS and applications. This proposed talk will discuss and present: (1) brief introduction to commercially available CSDs with built-in transparent compression, (2) experimental results that show, by replacing leading-edge normal SSD with CSD, one could reduce the storage cost by over 50% and meanwhile achieve 30% better Postgres TPS performance, and (3) experimental results that show CSD could meanwhile significantly reduce the Postgres write amplification, which enables the use of emerging low-cost QLC flash memory to further reduce the system storage cost. Finally, this proposed talk will discuss the potential of leveraging CSDs to improve the efficiency of important operations in Postgres.

Leading a Self-Organizing Team

description: One of the challenges of agile development is coming to grips with the role of leaders and managers of self-organizing teams. Many would-be ScrumMasters and agile coaches go to the extreme of refusing to exert any influence on their teams at all. Others retain too much of their prior command-and-control management styles and fail to unleash the creativity and productivity of a self-organizing team. Leading a self-organizing team can be a fine line. In this session you will learn the proper ways to influence the path taken by a team to solving the problems given to it. You will learn how to become comfortable in this role. You’ll understand why influencing a self-organizing team is neither sneaky nor inappropriate but is necessary. Drawing on analogies from fields such as evolutionary biology and the study of complex adaptive systems, the instructor will describe three factors necessary for self-organization to occur and then provide seven tools for guiding the direction taken by the team as they self-organize.

From a world with no WWW, no Linux, and no Open Source, we’ve come to a place where politically-motivated groups attack disease modellers on github over code used to inform government COVID-19 pandemic policy. The talk will introduce some ideas in spatial statistics, epidemiology, and disease surveillance. It will show how the landscape has changed and how Open Source and Open Data are now influencing the debate around disease surveillance in the COVID-19 era. I’ll outline how new technologies for reproducible research can bring about more openness and accountability for disease outbreak epidemiology.

description: State-of-play of the OGC API development. The work has been progressing, to develop various OGC API standards that support a variety of resources. API technologies are in focus of standardization discussions within the geospatial community. Discussions and initiatives in the OGC reached a milestone in 2018: the release of the first of the OGC API standards. Since then work has been progressing to develop additional OGC API standards supporting a variety of resources. OGC members & staff investigated the potential value that OpenAPI could offer to geospatial services. Existing web service standards were effectively web APIs, modernizing their means of getting content to the web required a fairly fundamental change in the underlying design. The first OGC API standard approved & published was Part 1 of the OGC API – Features standard. The pattern “OGC API [resource]” was coined and led to initiatives to define and test draft OGC APIs for Coverages, Maps, Tiles, Styles & Processes. Outputs will support the evolution of a solid, common core and the advancement of a new generation of OGC standards leveraging modern Web API approaches

description: The Locus Charter is an international set of principles and guidance for ethical and good practice in using location data. In 2019 the Omidyar Network funded 2 programmes of work looking at ethical implications of using location data - Benchmark Initiative in the UK and EthicalGEO in the USA. Since then the world has seen an unprecedented situation arise with the spread of COVID-19 across most countries in the world. Location data has been at the fore of understand, predicting and trying to manage the outbreak. A key topic that has arisen during this has been the question “what constitutes ethical use of location data?” This is being openly debated particularly in the use of contact tracing apps that are being developed by many governments across the world. The Locus Charter is a collaboration between the teams a Benchmark and EthicalGEO to develop an agreed set of international principles to help guide practitioners towards the ethical and responsible use of location data in their projects. The program will be reaching its public consultation phase in June.

description: We present a cloudbased technology, that allows “big geodata analysis” in process chains, that make use of actinia and GRASS GIS. Geo- and EO-data are more and more available, especially the growing Open Data policy of organisations fuels this process. With this awareness and demand for geo-based decision support increases. We want to present an implementation of the new paradigm of “bring processes to the data”. In the talk we present how big geodata analysis process chains could be easily implemented in a cloud environment by using GRASS GIS and actinia (OSGeo project & OSGeo Community project, respectively) for the process algorithms. The combination of these allows cloud optimized geodata processing triggered through simple API-calls. In the first part we show the architectural design and the interactions between actinia and GRASS GIS. In the 2nd part we present examples of process chains. These are a) automated surface-type detection from orthophotos, b) on-demand creation of cloud free Sentinel-2 scenes using temporal interpolation, and lastly c) gap-filling of high-resolution land surface temperature data from MODIS-satellite data.

Dynamic languages extend the boundaries even further, where we can bend the programming languages to our will. But what if we want to move beyond the barriers of the programming language and into actual external, executable DSLs? In this session, we'll look at the landscape of lexers, parsers, grammars and trees to see how we can use these tools to build external DSLs that business users will actually enjoy using. We'll also look at how we can take those trees and transform them into real, executable code. Finally, we'll see where to use external DSLs (and where not to use them) to build systems with truly dynamic behavior.

Our platform contains several maps and graphs depicting the different dimensions of the pandemic in Romania, ranging from confirmed cases/deaths/healed patients and related statistics, to hospital infrastructure, quarantine zones to pollution/mobility indexes, as well as other impact indicators of this epidemic in our country. Unfortunately, the Romanian authorities have failed in communicating the evolution of the COVID-19, resulting in numerous glitches in different reports. Thus, we have been volunteering our time to collect detailed information from the local/national media, compare it to the official reporting, sort it and deliver it in a structured manner. The application is built using Node.js, PostgreSQL+PostGIS, R on the backend and OpenLayers, Angular, charts.js, Plotly and D3.js for the frontend.

description: Learn how we tackled the tech challenges involved in processing a large volume of noisy, geospatial data, using FOSS and cloud computing. Large volumes of geotagged network data, are generated everyday using sensor devices. If processed, these data could have an important impact in location assessment and network design and planning. The main goal of this project was to identify Areas of Coverage (AoC) of telco antennas, within a large volume of noisy, point data. This brought two technological challenges: to find an algorithm that enabled us to detect the AoC, discarding the points which are not relevant; and to run this algorithm at scale, processing a large dataset, which covers the entire UK. The two challenges were tackled using a stack of FOSS. The resulting application was virtualised into a set of docker containers, and deployed on the AWS cloud, where the processing took place. In this presentation, we would like to present the final pipeline that successfully transformed the signals in AoC, and share some lessons learned during the design, implementation and deployment process.

description: The talk presents one Open Source toolset for the set-up of geodata-services that consists of GeoServer/GeoWebCache, GeoStyler and MapProxy. Just a few years ago, the very existence of geo-services based on an uniform API alone aroused admiration. Now more than 10 years of INSPIRE later, this question often no longer arises. With UMN MapServer, GeoServer, deegree or QGIS Server, to name just a few, there are a number of software packages in the Open Source world, that can be used to transform geodata into standardized services. Once published as WMS or WFS, one can rely on a whole range of additional tools, functions and interfaces. Thus a user is often faced with the question on which tools can be used to achieve an optimal result in the shortest possible time. In my talk I present one possible solution for setting-up of geodata-services. I want to show functions, possibilities and interactions of the OSGeo project GeoServer & GeoWebCache with the OSGeo Community Projects GeoStyler and MapProxy based on some examples. The talk is peppered with some hints on styling, performance tuning and caching of services.

description: Learn how to create an on-demand pay-as-you-go PostGIS database with Amazon Aurora. PostGIS, the leading relational spatial database, is now available to use with Amazon Aurora Serverless for Postgres. Amazon Aurora Serverless is differentiated from existing cloud database solutions because it supports a fully on-demand configuration. The database scales automatically when under load, and can be configured to shutdown completely when not in use. In its “cold” state the user only pays for data stored, making this ideal for variable workloads and price-sensitive applications. This demonstration will introduce the key concepts of Aurora Serverless, and showcase database creation, configuration, and loading data via QGIS. The session is suitable for anyone who is familar working with PostGIS databases. The session will conclude with how to perform a query to the database without a connection, using the Aurora Data API in a Lambda function. Requirements: knowledge of how to create a PostGIS database, an Amazon Web Services account if you want to follow along at home.

The lack of availability of quantum computers makes it beneficial to centralize the power of quantum computers, using a SaaS model to democratize access to them, therefore making the cloud a suitable home for quantum computing. The first part of the session introduces an open-source co-processor model where classical computers can offload specialized tasks that are better suited to quantum computers thus lowering the onramp to incorporating quantum computing into applications today. The next part of the sessions demonstrate how to build a co-processor model on the cloud using two community operators that provide quantum acceleration by leveraging Qiskit, an open-source SDK for developing quantum circuits, classical components powered by Red Hat OpenShift and IBM Quantum Experience as the quantum backend The session concludes with a small demonstration of how to run a quantum circuit on the cloud using the co-processor model.

description: With Kubernetes gaining popularity for performance-critical workloads such as 5G, Edge, IoT, Telco, and AI/ML, it is becoming increasingly important to meet stringent networking and resource management requirements of these use cases. Performance-critical workloads like these require topology information in order to use co-located CPU cores and devices. Despite the success of Topology Manager, aligning topology of requested resources, the current native scheduler does not select a node based on it. It's time to solve this problem! We will introduce the audience to hardware topology, the current state of Topology Manager, gaps in the current scheduling process, and prior out-of-tree solutions. We'll explain the workarounds available right now: custom schedulers, creating scheduling extensions, using node selectors, or manually assigning resources semi-automatically. All these methods have their drawbacks. Finally, we will explain how we plan to improve the native scheduler to work with Topology Manager. Attendees will learn both current workarounds, and the future of topology aware scheduling in Kubernetes. Kubernetes has taken the world by storm attracting unconventional workloads such as HPC Edge, IoT, Telco and Comm service providers, 5G, AI/ML and NFV solutions to it. This talk would benefit users, engineers, and cluster admins deploying performance sensitive workloads on k8s. Addition of newer nodes running alongside older ones in data centers results in hardware heterogeneity. Motivated by saving physical space in the data centers, newer nodes are packed with more CPUs, enhanced hardware capabilities. Exposing to use fine grain topology information for optimised workload placement would help service providers and VNF vendors too. We’ll explain numerous challenges encountered in efficiently deploying workloads due to inability to understand the hardware topology of the underlying bare metal infrastructure and scheduling based on it. Scheduler’s lack of knowledge of resource topology can lead to unpredictable application performance, in general under-performance, and in the worst case, complete mismatch of resource requests and kubelet policies, scheduling a pod where it is destined to fail, potentially entering a failure loop. Exposing cluster level topology to the scheduler empowers it to make intelligent NUMA aware placement decisions optimizing cluster wide performance of workloads. This would benefit Telco User Group in kubernetes, kubernetes and the overall CNCF ecosystem enabling improved application performance without impacting user experience.

Something that “just works” as intended, without the need to fiddle around much to get to a working desktop that does its job and otherwise gets out of your way? Say "hello" to helloSystem, a desktop system for creators with focus on simplicity, elegance, and usability. Presentation and Live walktrough of a running helloSystem desktop. helloSystem is FreeBSD preconfigured as a desktop operating system. Its design follows the “Less, but better” philosophy. It is intended as a system for “mere mortals”, welcoming to switchers from a world in which a global menu bar exists, the Command key is used rather than Control, and applications are contained in .app bundles. helloSystem aims at providing a "it just works" out-of-the-box user experience in which a non-technical user can just use the system without ever opening the terminal, without having to configure anything, and without ever seeing white text on a black background scroll by during system boot.One objective for helloSystem is to be both easy to use for “mere mortals” yet powerful under the hood for advanced users, a combination that had been skillfully mastered in the first releases of Mac OS X. So the question is, can we take this objective of being easy but powerful but take it even further than Apple ever did?

description: The term brain-computer interface is well known among engineers, tinkerers, and specifically among researchers. Companies like BackYard Brains made it accessible for all at a relatively affordable price, with their initiative of neuroscience for all. The price of their device and the ease of usability it comes with is pretty good for a school student who's just looking for an introduction to neuroscience but, the resolution of Arduino's ADC (10bit) doesn't allow it to be used for any real neuroscience research project. The company called OpenBCI also creates some good hardware for Biopotential amplification (4/8ch 24bit) and their hardware is much more capable but, it's very costly and certainly not for everybody. As an engineer myself, I believe we can create much cheaper hardware for Brain-Computer interface devices than currently available in the market without losing any signal quality. I have started working on some prototypes already and one of the devices is called BioAmp v1.5 which takes benefit of the already available high-resolution ADC input of your computer which is normally used to record audio. The device basically converts the muscle into an audio source and provides us with the option to directly listen to it using earphones OR to visualize/record the signal on our mobile/laptop using Audacity/BYB Spike Recorder.

Glasgow is a tool for exploring digital interfaces, aimed at embedded developers, reverse engineers, digital archivists, electronics hobbyists, and everyone else who wants to communicate to a wide selection of digital devices with high reliability and minimum hassle. It can be attached to most devices without additional active or passive components, and includes extensive protection from unexpected conditions and operator error. The Glasgow hardware can support many digital interfaces because it uses reconfigurable logic. Instead of only offering a small selection of standard hardware supported interfaces, it uses an FPGA to adapt on the fly to the task at hand without compromising on performance or reliability, even for unusual, custom or obsolete interfaces.

description: OpenStack today is a complicated beast -- not only does it try to perform well for large clusters, but it also embraces a diverse set of possible implementations from hypervisors, storage, networking, and more. This was a deliberate tactical choice made by the OpenStack community years ago, forming a so called "Big Tent" for vendors to collaborate in to build Open Source cloud options. It made a lot of sense at the time to be honest. However, OpenStack today finds itself constrained by the large number of permutations it must support, ten years of software and backwards compatability legacy, and a decreasing investment from those same vendors that OpenStack courted so actively. OpenStack Compute wasn't always like this though. The first public git commit had about 5,000 lines of code in it, and was surprisingly functional. What would a simpler and more opinionated IaaS compute component look like? Especially if it could take advantage of the general improvement of Open Source tooling in the last decade that OpenStack has driven? This was what I was pondering in late 2019 as I started to drift away from the OpenStack community for various reasons. Then, a series of natural disasters in Australia and globally presented me with an opportunity to cancel all my extracurricular activities and really give an experiment a go. That experiment is called Shaken Fist (as in old man shakes fist at cloud), is about the same size as the original OpenStack Compute commit, and is available at the Website: shakenfist. I'd appreciate the opportunity to discuss some of the simplifying assumptions made, what functionality is available, whether the experiment tells us anything interesting, and possible future directions.

Was gibt es Neues bei gvSIG CE?

uk: Комп'ютерні науки

description: Nach dem letzten Code Sprint (22.-25.11.2013 in Berlin) hat das Core Developer Team von gvSIG CE ein roadmap bearbeitet für die nächsten Versionen dieses Open Source Desktop GIS Projektes. In diesem Vortrag werden die neuen Funktionalitäten der Version 1.0 vorgestellt sowie der aktuelle Stand des Projektes. Bei der Entwicklung von gvSIG CE wird darauf Wert gelegt, die bestmögliche Integration anderer Open Source Software zu gewährleisten. GDAL, proj4, SEXTANTE, GRASS GIS, OpenCADTools und NavTable sind einige Beispiele. Ab dem Code Sprint von 2012 in München wurde das gvtool Projekt gestartet, mit dem man die Integration von geotools weiter entwickeln wird. gvSIG CE 1.0 wird GDAL 1.10 benutzen, um Raster Daten lesen zu können u.a. auch die Formate ECW, JP2 y MrSID. Bei dieser Entwicklung wurden die offiziellen bindings von gvSIG ersetzt durch die von GDAL. Die java Version von SEXTANTE wird hauptsächlich vom gvSIG CE Team weiter entwickelt. Im März 2013 hat unser Team eine neue Version von SEXTANTE ins Leben gerufen mit einer effizienteren Anbindung an GRASS GIS. Die Erweiterung ExtCad, die in der offiziellen Version von gvSIG benutzt wird, wurde durch eine aktuelle und verbesserte Version des Open Source Projektes OpenCadTools ersetzt. Zusammen mit den Entwicklern von OpenCadTools wurde eine bessere Version ins Leben gerufen, mit der sich die Editiermöglichkeiten von gvSIG CE deutlich verbessern. Das gvSIG CE Team hat verschiedene Maßnahmen durchgeführt mit dem Ziel, die Pflege und den weiteren Aufbau der Software einfacher zu machen. Diese Änderungen sowie die neuen Funktionen, die entwickelt worden sind, würden wir gerne bei der kommenden FOSSGIS Konferenz vorstellen.

description: Open Source ist auf der einen Seite ein Entwicklungsmodell und auf der anderen ein Lizenzmodell. Zusammen bilden sie eine Kultur offener Entwicklungsgmemeinschaften, die höchst effektiv arbeiten. Diese Kultur ist um ein Vielfaches effektiver, als proprietäre Modelle es je sein können. Unter anderem sieht man das an einfachen Beispielen: Das Betriebssystem des Herstellers Apple basiert vollständig auf dem Open Source Unix FreeBSD. Es gibt halt einfach nichts besseres, und es selbst herzustellen wäre unendlich teuer. Sogar der hyper-proprietäre Hersteller Apple hat das eingesehen. Der Vortrag stellt die Geschichte der Entwicklung von Open Source vor und geht auf wichtige Grundlagen ein. Ziel des FOSSGIS e.V. und der OSGeo ist die Förderung und Verbreitung freier Geographischer Informationssysteme (GIS) im Sinne Freier Software und Freier Geodaten. Dazu zählen auch Erstinformation und Klarstellung von typischen Fehlinformationen über Open Source und Freie Software, die sich über die Jahre festgesetzt haben.

description: GRASS GIS (Geographic Ressourcen Analysis Support System) blickt mit nun 30 Jahren auf die längste Entwicklungsgeschichte in der FOSSGIS Community zurück. Die stark ansteigende Nachfrage nach robusten und modernen freien Analysewerkzeugen, v.a. im Hinblick auf die heutzutage enormen räumlichen Datenmengen führte 2008 zum Beginn der GRASS GIS 7 Entwicklung. In Bezug auf GRASS GIS 6.4 wurden inzwischen mehr als 10.000 Verbesserungen vorgenommen. Die Entwicklercommunity hat eine Reihe von neuen Modulen für Vektornetzwerkanalyse, Bildverarbeitung, Voxelanalyse, Zeitreihenspeicherung (Raster, Vektor, Voxel) und eine verbesserte grafische Benutzeroberfläche integriert. GRASS GIS 7 bietet eine neue Python Schnittstelle, die auf einfache Weise ermöglicht, neue Anwendungen zu erstellen, die leistungsfähig und effizient sind. In der Benutzeroberfläche gibt es nun ein neues Werkzeug für die Animation von Raster-und Vektorkartenzeitreihen, einen verbesserten Georektifier, ein neues Werkzeug zur überwachten Bildklassifikation, einen "map swiper" zum interaktiven Vergleich zweier Karten (z.B. für Katastrophen) und ein visuelles Zeitreihenmanagement. Darüber hinaus wurde insbesondere die topologische Vektorbibliothek in Bezug auf die Unterstützung von großen Dateien verbessert. Des weiteren gibt es eine Reihe von neuen Analysefunktionen und auch im Raster-/Bildbereich die Unterstützung für massive Datenanalyse. Auch werden nun Projektionen andere Planeten unterstützt. Viele Module wurden in Bezug auf Geschwindigkeit signifikant optimiert. Der Vortrag illustriert die interessantesten Neuerungen und zeigt, wie Benutzer auf einfache Weise auf die kommende GRASS GIS 7 Version migrieren können.

description: Das gemeinsame Forschungsprojekt ArcoFaMa der Beuth Hochschule für Technik Berlin und der Hochschule für Technik und Wirtschaft Berlin schlägt einen Bogen über die Fachgebiete Datenbanksysteme, Geoinformation und Facility Management (FM). Zielstellung ist die Entwicklung einer Integrationsplattform für heterogene Datenquellen und -formate und deren Nutzung zur Integration von Datenbeständen des Projektpartners Botanischer Garten Berlin-Dahlem. Insbesondere Geodaten und FM-Fachdaten, die im operativen Einsatz üblicherweise in proprietären Datenhaltungssystemen getrennt behandelt werden, sollen integriert werden. Die Geodaten werden aus Vermessungsdaten des Außengeländes des Botanischen Gartens Berlin-Dahlem abgeleitet. Dazu werden die Vermessungsdaten in verschiedenen Arbeitsschritten extrahiert und semantisch angereichert, georeferenziert und in das CityGML-Format transformiert. Über die Integrationsplattform werden diese Daten u.a. mit Daten aus dem Facility Management verknüpft, die im IFC-Standard vorliegen. Die Integrationsplattform benutzt eine Graph-Datenbank als Metadatenspeicher. Durch das Knoten-Kanten-Datenmodell der Graph-Datenbank können sehr effizient vernetzte Strukturen abgebildet werden. Dies wird im Projekt für die virtuelle Integration der autonomen Datenquellen eingesetzt. Der Beitrag wird über den gewählten Ansatz zur Entwicklung der Integrationsplattform sowie die Besonderheiten des Datenmodells und die Transformationsschritte berichten sowie einen Einblick in das interdisziplinäre Forschungsprojekt geben.

Quo vadis Open Source?

uk: Комп'ютерні науки

description: Die FOSSGIS-Szene befindet sich heute im Spannungsfeld zwischen traditionellen Leitmotiven und manchmal schwer erfüllbarem kommerziellem Erfolgsanspruch. Dieser Vortrag macht es sich zum Anliegen, einige bedenkliche Entwicklungen in dieser Situation zu thematisieren. Open-Source-GIS existieren seit rund drei Jahrzehnten und bereichern mit ihren frei verfügbaren Innovationen unsere Gesellschaft in demselben Maße, wie sie es privaten, akademischen und kommerziellen Nutzern erlauben, sich im Umgang mit räumlicher Information zu emanzipieren. Allerdings scheint dabei mitunter in Vergessenheit zu geraten, dass "Open Source" mehr als ein Mittel zum Zweck ist. Wenngleich weniger vordergründig als bei der "Freien Software", vertritt auch der Begriff "Open Source" eine gesellschaftliche Idee, die mit den Kommunikationsmöglichkeiten des Internets perfekt harmoniert und dadurch zu einer technologisch-sozialen Erfolgsgschichte geworden ist. Die moderne FOSSGIS-Welt wirkt jedoch zunehmend professionalisiert und gleichzeitig kommerzialisiert, mit allen bekannten, positiven wie negativen Effekten. Nicht immer ist hierbei erkennbar, dass die übergeordneten Interessen der "Community" ausreichend vertreten werden. So scheinen die Suche nach langfristig funktionierenden Geschäftsmodellen und der Ausbau von "Public Relations" manchmal eine ebenso hohe Priorität zu besitzen, wie die Produktion funktionierender Software. Selbst Auswüchse moderner Wirtschaftsformen, wie die Schaffung von Monopolen auf Kosten von Diversität, lassen sich in Ansätzen erkennen. Dass dies jedoch nicht unbedingt mit tatsächlichem kommerziellem Erfolg einhergeht, zeigt die nach wie vor überschaubare Zahl langfristig aktiver Desktop-GIS-Projekte und in diesem Bereich tätiger Programmierer. Die steigenden technologischen Einstiegshürden, in Form immer "modernerer", d.h. komplexerer und kurzlebigerer, APIs und Werkzeuge zur Online-Kollaboration, verschärfen dieses Problem nur noch weiter. So findet sich die FOSSGIS-Szene heute im Spannungsfeld zwischen traditionellen Leitmotiven und manchmal schwer erfüllbarem kommerziellem Erfolgsanspruch. Dieser Vortrag macht es sich zum Anliegen, einige bedenkliche Entwicklungen in dieser Situation zu thematisieren.

OSM in Jerusalem

uk: Комп'ютерні науки

description: Im laufenden Forschungsprojekt zu OpenStreetMap in Israel/Palästina" am Institut für Geographie der Universität Erlangen-Nürnberg werden politische Dimensionen von Web 2.0-Kartographie in einem spannungsgeladenen sozialen Umfeld untersucht. Die offen zugängliche OSM-Datenbank bietet eine neuartige Gelegenheit, Forschungsfragen zur Entstehung und sozialer Prägung von Geodaten empirisch zu bearbeiten. Der Vortrag wird einen Überblick zum Projekt geben und erste Ergebnisse präsentieren. Am Fallbeispiel von Jerusalem, als extrem fragmentierten und segregierten Sozialraum, sollen gesellschaftliche Strukturierungen der OSM-Datenbank veranschaulicht werden. Anhand geo-statistischer Auswertungen der Daten und Metadaten zu Jerusalem, sowie deren Triangulierung mit statistischen Bevölkerungsdaten auf Wohnbezirksebene kann gezeigt werden, dass generell säkular-jüdisch bewohnte Gebiete in weitaus höherem Detailgrad kartiert wurden als ultraorthodox-jüdische und palästinensische. Im Anschluss an andere Arbeiten lassen sich die Ergebnisse zurückführen auf Tendenzen, nach denen sich die Beitragenden bei OSM -- ähnlich wie bei anderen Crowdsourcing-Projekten -- aus einer bestimmten soziodemographischen Gruppe rekrutierten. Hieraus wiederum ergeben sich Fragen nach gesellschaftlicher Repräsentativität, bzw. Marginalisierung, die die scheinbar neutralen und unpolitischen Geodaten überprägen.

description: OpenJUMP ist ein leichtgewichtiges und leicht zu erlernendes Open Source Desktop GIS. Durch seine Plattformunabhängkeit läuft es auf recht unterschiedlich ausgestatteter Hardware. Der Vortrag wird einen kurzen Überblick über die Funktionsbereiche (Erfassung/Bearbeitung, Analyse/Auswertung, Qualitätskontrolle) geben. Über Neuigkeiten und Aktuelles aus der Entwicklung wird ebenfalls berichtet. Der zweite Teil berichtet vom Einsatz im öffentlichen Sektor. Speziell geht es darum, wie es möglich ist Open Source Software an proprietäre Systeme anzukoppeln. In der Praxis nützt das schönste GI System nichts, wenn es nicht mit der Sachdatenanwendung interagieren kann. Leider kann man als Open Source Entwickler kein NDA (Non Disclosure Agreement) unterschreiben, um an die Schnittstellenbeschreibungen zu kommen. Das es dennoch möglich ist, zeigt ein OpenJUMP Plugin. Es dient zum bidirektionalen Datenaustausch bzw. der Kopplung mit einer, im kommunalen Bereich, weit verbreiteten Software. Die Lösung komplexer Aufgabenstellungen gelingt mit der geschickten Kombination aus mehreren Open Source GIS Tools. Die Berechnung der Einsatzreichweiten der freiwilligen Feuerwehren im Rahmen der Risiko- und Gefährdungsanalyse einer Kommune ist so ein Beispiel. Für die Erfassung und Bearbeitung diente OpenJUMP. Luftbilder, topographische Karten wurden durch den "GeoServer" als WMS bereit gestellt. Die Datenaufbereitung und das Routing erledigte dann die "PostGIS" Datenbank. Gegenüber einer einfachen statischen Bufferbildung förderte das erstaunliche Ergebnisse zu Tage.

Neues von OSM2World

uk: Комп'ютерні науки

description: Die freie 3D-Renderingsoftware OSM2World bietet ihren Anwendern nun schon seit über 3 Jahren die Möglichkeit, die OpenStreetMap-Daten in einer ansprechenden dreidimensionalen Darstellung aufzubereiten. Allerdings haben sich sowohl das Projekt OpenStreetMap als auch die verfügbaren Technologien inzwischen weiterentwickelt. Immer detailreichere Daten wollen visualisiert werden, und neue Trends wie WebGL -- eine Möglichkeit zur Hardwarebeschleunigten Darstellung dreidimensionaler Inhalte im Webbrowser -- bieten neue Chancen, aber auch Herausforderungen. Gleichzeitig lässt das Thema 3D in OpenStreetMap allmählich seinen Nischendasein hinter sich und neue Anwendungsfelder entstehen. Wegen des steigenden Interesses steigen mittlerweile auch kommerzielle Anbieter mit proprietärer Software in das Themenfeld ein. Dieser Vortrag erzählt, wie OSM2World auf diese Entwicklungen reagiert. Der Besucher erfährt, was sich bei OSM2World im letzten Jahr getan hat, aber auch was die Zukunft bringen wird.

GeoCouch

uk: Комп'ютерні науки

description: Bei Apache CouchDB und Couchbase handelt es sich um sogenannte dokumentbasierte Datenbanken. Sie gehörten somit in die Kategorie der nicht-relationale Datenbanksysteme für die sich der Sammelbegriff NoSQL" eingebürgert hat. Eine Stärke von Apache CouchDB ist die (Multi-Master) Datenreplikation. Das bedeutet dass der Datenbestand verschiedener Datenbankinstanzen synchron gehalten werden kann, und dennoch Änderungen an beliebiger Stelle vorgenommen werden können. Die Replikation beschränkt sich nicht nur auf Apache CouchDB, sondern mittlerweile auf ein gesamtes Ökosystem. So ist es möglich Daten mittels HTML5-Technologie mit einem Browser zu synchronisieren. Diese stehen dem Anwender somit auch offline zur Verfügung, ohne dass eine Verbindung zu einem Server bestehen muss. Couchbase hingegen hat seine Stärke bei der Skalierung des Systems. So werden die Daten automatisch auf mehrere Rechner verteilt. Das nachträgliche Hinzufügen oder Entfernen von Rechnern ist über eine Web-Oberfläche sehr leicht möglich. Im Falle des Ausfalls eines Rechners läuft das System ohne Unterbrechung weiter. Couchbase bietet zudem Couchbase Lite an, dass eine Datenbank für Mobile Geräte darstellt. Dabei wird das Replikationsprotokoll von Apache CouchDB sowohl für Android als auch iOS implementiert. Somit ist es möglich Applikationen zu schreiben, die auch ohne ständige Internetverbindung funktionieren. GeoCouch bietet sowohl für Apache CouchDB als auch Couchbase eine Lösung um n-dimensionale Anfragen machen zu können. Es ist also nicht nur möglich räumlich Anfragen zu stellen, sondern weitere Eigenschaften wie z.B. Zeit, Größen oder beliebige andere numerische Werte mit einzubeziehen. In diesem Vortrag wird per Live-Coding gezeigt, wie leicht es ist eine Mobile Applikation zu Entwickeln, die die oben beschriebenen Technologien verwendet. Apache CouchDB, Couchbase, Couchbase Lite und GeoCouch sind Open-Source und stehen unter der Apache License Version 2.0.

description: Um einen sicheren und geordneten Ablauf des Flugverkehrs zu gewährleisten, sind verlässliche Informationen zu den aktuellen Verkehrsbedingungen für alle Beteiligten, wie z.B. Piloten und Fluglotsen, von entscheidener Bedeutung. Für die Bereitstellung der aktuellen Informationen bezüglich Luftraumstruktur, Flugplätzen, Flugrouten und Flugsicherungsverfahren wird AIXM 5.1, der Standard für den weltweiten Austausch von aeronautischen Informationen, eingesetzt. Dieser Standard wurde gemeinsam von der FAA und EUROCONTROL in Form eines Applikation Schemas auf Basis von GML entwickelt (www.aixm.aero). Die Übertragung der AIXM Messages kann ähnlich wie bei den INSPIRE Download Services über das OGC WFS 2.0 Protokoll abgewickelt werden. Die Anforderungen an das GML Framework sind jedoch ungleich höher. Neben den komplexen Geometrie Objekten stellt insbesondere das AIXM Temporality Model, in dem die zeitliche Komponente der aeronautischen Information beschrieben wird, eine Herausforderung dar. In dem Vortrag wird gezeigt, wie eine erfolgreiche Umsetzung von AIXM WFS Services mit dem deegree Framework gelungen ist und wie sich mit der leistungsfähigen GML API die Verarbeitung von AIXM Daten problemlos gestaltet. Am Beispiel eines Spatial Processing Services und eines AIXM Business Rules Validators werden die professionellen Einsatzmöglichkeiten von AIXM Web Processing Services (WPS) mit dem deegree Framework demonstriert.

description: Es gibt einige Projekte mit dem Ziel Gebäude, Wege und andere Objekte aus dem OpenStreetMap-Datenbank parametrisch in 3D darzustellen. Selbstverständlich solchem Vorgehen fehlt realistisches Aussehen. Ziel dieses Projekts ist nach realistischem Aussehen von Orten zu streben. Dafür werden manuell erstellte 3D-Modelle von Gebäuden und anderen Objekten verwendet. Sowohl für 3D-Modellierung als auch für Rendering wird ein Open Source Programm Blender verwendet. Komplexe Berechnungen in 3D werden auch mit Hilfe von Blender durchgeführt. OpenStreetMap Daten werden ins Blender importiert um Georeferenzierung von jedem manuell erstellten 3D Gebäude durchzuführen. Ein 3D Modell wird durch Ziehen und Drehen über der importierten OSM-Karte an der richtigen Stelle platziert. Die entsprechenden geographischen Koordinaten und das Drehwinkel werden in einer Datenbank gespeichert. Somit entsteht das 3D-Modell des ganzen Ortes, das man in verschiedener Art und Weise anwenden kann. Als Beispiel dieses Ansatzes werden 2.5D Karten betrachtet. Unter der 2.5D Karte versteht man eine ganz herkömmliche Karte in Web Mercator-Projektion mit einer Oberfläche aus einzelnen 3D Gebäuden, die in Schrägprojektion vertikal nach unten dargestellt sind.

Die Erweiterbarkeit dieser proprietären Software um eigene Geobasisdaten (z.B. verbesserte, hoch detaillierte Höhenmodelle) oder um eigene Funktionalität ist jedoch sehr eingeschränkt. Der quelloffene OpenWebGlobe (www.openwebglobe.org) ermöglicht die Realisierung massgeschneiderter, leistungsfähiger Virtueller Globen mit lokalen bis globalen Geodatensätzen und eigener Funktionalität. Der OpenWebGlobe Viewer basiert auf den neuen Web-Technologien HTML5 und WebGL ist daher in den meisten modernen Web-Browsern ohne vorgängige Installation eines Plugins lauffähig. Mithilfe von OpenWebGlobe wird eine Echtzeit 3D-Repräsentation von OpenStreetMap Daten auf einem Virtuellen Globus realisiert. Dabei wird direkt mit OSM Daten in der Postgres Datenbank gearbeitet. Die Resultate werden über 3D-Geometrie Tiles in einem JSON Format zurückgegeben. Dabei werden level of detail und caching-Strategien eingesetzt.

description: The next generation of weather and climate models will have an unprecedented level of resolution and model complexity, and running these models efficiently will require taking advantage of future supercomputers and heterogeneous hardware. In this paper, we investigate the use of mixed-precision hardware that supports floating-point operations at double-, single- and half-precision. In particular, we investigate the potential use of the NVIDIA Tensor Core, a mixed-precision matrix-matrix multiplier mainly developed for use in deep learning, to accelerate the calculation of the Legendre transforms in the Integrated Forecasting System (IFS), one of the leading global weather forecast models. In the IFS, the Legendre transform is one of the most expensive model components and dominates the computational cost for simulations at a very high resolution. We investigate the impact of mixed-precision arithmetic in IFS simulations of operational complexity through software emulation. Through a targeted but minimal use of double-precision arithmetic we are able to use either half-precision arithmetic or mixed half/single-precision arithmetic for almost all of the calculations in the Legendre transform without affecting forecast skill.
