Description LOFAR, the Low Frequency Array, is an innovative new radio telescope in the Netherlands, which will continuously monitor the radio sky. The study of transient sources is one of the key science projects of LOFAR. Under this remit come all time-variable astronomical radio sources, including pulsars, gamma-ray bursts, X-ray ...
Description In an ideal world, scientific applications are computationally efficient, maintainable, composable and allow scientists to work very productively. In this talk we demonstrate that these goals are achievable for a specific application domain by choosing suitable domain-specific abstractions implemented in Python that encapsulate domain knowledge with a high degree ...

Description Random Forests are without contest one of the most robust, accurate and versatile tools for solving machine learning tasks. Implementing this algorithm properly and efficiently remains however a challenging task involving issues that are easily overlooked if not considered with care. In this talk, we present the Random Forests ...
Description Parallel and asynchronous computing in python is crippled by pickle's poor object serialization. However, a more robust serialization package would drastically improve the situation. To leverage the cores found in modern processors we need to communicate functions between different processes -- and that means callables must be serialized without ...
Description In the field of X-Ray diffraction, 2D area detectors like ccd or pixel detectors have become popular in the last 15 years for diffraction experiments thanks to the large solid-angle coverage and to their better signal linearity. These detectors have a large sensitive area of millions of pixels with ...
Description The [Astropy Project](http://www.astropy.org/) is a community effort to develop a single core package for Astronomy in Python and foster interoperability between Python astronomy packages. In addition an ecosystem of [Astropy affiliated packages](http://www.astropy.org/affiliated/index.html) is growing, some of which are planned for inclusion in the Astropy core when they are matured, ...
Description Scientific simulation models often need to incorporate many aspects into a working software system. This talk gives an overview of [PITLAKQ](http://www.pitlakq.com/), a complex, coupled model for water quality predictions of pit lakes. The focus is on experiences gained that might be useful for similar projects from other domains. This ...
Abstract Plotly's Python API and sandbox let you make and share beautiful, web-based plots. This talk will be a walk-through of Plotly's library. We will craft and embed interactive graphs within an IPython Notebook from our gallery, use Plotly's GUI to edit and share graphs, and use Plotly's matplotlib wrapper ...
Description Vispy is an OpenGL-based interactive visualization library in Python. Its goal is to make it easy to create beautiful and fast dynamic visualizations. For example, scientific plotting of tens of millions of points, interacting with complex polygonial models, and (dynamic) volume rendering. Vispy is a young library and very ...
Description This talk will discuss the design and implementation of a Python-based tool- set to aid in assessing the response of the UK's Advanced Gas Reactor nuclear power stations to earthquakes. The seismic analyses themselves are carried out with a commercial Finite Element solver, but understanding the raw data this ...
Abstract Biggus is a lightweight pure-Python package which implements lazy operations on numpy array-like objects. This provides dramatically improved efficiency in analysing large datasets, for minimal additional effort in the client code. Description As scientific datasets continue to grow exponentially in size, the resource requirements of even simple analyses can ...
Description Neural networks with many layers are known as "deep" neural networks. While the phrase "deep learning" to describe deep neural networks is new, the ideas behind these networks have been around for many years. Deep neural networks attempt to learn concise, hierarchical representations of complex data, and recent advances ...
SunPy for Solar Physics Oct. 22, 2014
Description SunPy is a data-analysis library specialising in providing the software necessary to analyse solar and heliospheric datasets in Python. SunPy is open- source software (BSD licence) and has an open and transparent development workflow that anyone can contribute to. SunPy provides access to solar data through use of the ...
How To Shut Down Tolkien Oct. 20, 2014
Description While Tolkien had friends who could devise ingenious ways to critique his work without sounding critical, he had others whose remarks were merciless and direct — to the point that Tolkien simply stopped sharing new chapters as he wrote The Lord of the Rings. As programmers we share many ...

Description This is an expert-level talk that dives into CPython and discusses various ways to embed Python interpreters. It starts with the "very high level" embedding & the "pure" embedding, shows a fairly novel "zero interpreter" embedding using Cython, a few attempts at a ctypes/cffi embedding, and builds to a ...
Description Making nice interactive data visualizations in the browser should be easy and fun! Let's explore tweets with simple IPython notebooks, a Blaze interface and Bokeh plots! Bokeh is a Python interactive visualization library that targets modern web browsers for presentation. Its goal is to provide elegant, concise construction of ...
