Put an "Actor Model" in your House

The Internet of Things with the explosion of sensor adds a lot of challenges in how to deal with all of these simultaneously connected devices producing lots of data to be retrieved, actors have delivery guarantees and isolation properties that are perfect for the IoT world. The session will show how to implement an actor base home automation system. The actor model with the characteristics of elastic and decentralized by design, is the perfect solution for IOT environment. With actor is possible to create a simple concurrency and distributed system that react on the events. The talk will give an overview on the existing technologies and implementation, it will show also the experience of build an home automation system with an actor model with the description of the challenges and the solution adopted.

Geospatial web services using little-known GDAL features and modern Perl middleware

GDAL has a little-known feature vsistdout redirect, which is a virtual file system driver that can redirect standard output to any GDAL virtual file. This feature is exploited in GDAL 2.1 Perl bindings to make streaming objects possible. Streaming objects are objects, which belong to a class, which implement 'write' and 'close' subroutines. Such objects happen to be important in modern Perl web middleware, code that are based on PSGI - Perl Web Server Gateway Interface Specification. In this talk I will present a suite of new Perl modules, which implement OGC geospatial web services. I have two of these modules already in production use, one for raster tile service and one for feature service. In this talk I will present and discuss how GDAL and Perl have made it easy to develop and extend these services. Ari Jolma (Private)

Big Data Analytics at the MPCDF: GPU Crystallography with Python

Big Data Analytics at the MPCDF: GPU Crystallography with Python [EuroPython 2017 - Talk - 2017-07-12 - Anfiteatro 1] [Rimini, Italy] In close collaboration with scientists from MPG, the Max Planck Computing and Data Facility is engaged in the development and optimization of algorithms and applications for high performance computing, as well as in the design and implementation of solutions for data-intensive projects. Python is now used at MPCDF in the emerging area of “atom probe crystallography” (APT): a Fourier spectral analysis in 3D reciprocal space can be simulated in order to reveal both composition and crystallographic structure at the atomic scale of billions APT experimental data sets. The Python data ecosystem has proved to be well suited to this, as it has grown beyond the confines of single machines to embrace scalability. This talk aims to describe our approach to scaling across multiple GPUs, and the role of our visualization methods too. Our data workflow analysis relies on the GPU-accelerated Python software package called PyNX, an open source Python library which provides fast parallel computation scattering. The code is well suited for GPU computing, using both the pyCUDA and pyOpenCL libraries. Exploratory data analysis and performance tests are initially carried on through Jupyter notebooks and Python packages e.g., pandas, matplotlib, plotly. In production stage, interactive visualization is realized by using standard scientific tool, e.g. Paraview, an open-source 3D visualization program which e.g. requires Python modules to generate visualization components within VTK files

A discussion of Fedora's Legal state

Tom Callaway, the Fedora Legal chair, will talk about the past, present, andfuture of licensing and legal issues in the Fedora community. Tom is not alawyer, nor does he play one on TV, but he does consult with lawyers, andoccasionally, go drinking with them. Bring your questions, and he'll do hisbest to answer them. I am not a lawyer, so nothing in my presentation shouldbe (or could be) construed as legal advice. Fedora, as the evolution of Red Hat Linux, is one of the oldest and most wellknown Linux distributions in existence today. For more than 10 years, I havebeen the Fedora Legal representative who investigates licenses, negotiateswith lawyers, advises our community, and does everything in my power to nothave to tell people "no" without a very good reasoning. In my presentation, I'll discuss the past, present, and future of licensingand legal issues in the Fedora community (and beyond). I'm also happy to takequestions from the FOSDEM audience as to why Fedora does what it does (ordoesn't do what it doesn't do). I am not a lawyer, so nothing in my presentation should be (or could be)construed as legal advice. I am however, a well informed hacker, and theeditor/maintainer of possibly the largest list of FOSS licenses in existence.
