onFOSS
@[email protected]onFOSS is an online, "Free (as Freedom) and Open Source" LAN-Party. The goal is to get people together, enjoying the art of computer games and having a great time in these days. The FOSS community is a place of being open minded and acceptance to all different kinds of people with the focus of fully transparent systems and protecting individuals. So it does not matter if you are on Windows, Mac or Linux and it is also NOT necessary to have a PC MASTERRACE setup to run those games.
ObsPy Dev Team
@[email protected]
We make code that lets other people make code that makes us understand the piece of rock we sit on better.
Or to put it in other words..
ObsPy is an open-source project dedicated to provide a Python framework for processing seismological data. It provides parsers for common file formats, clients to access data centers and seismological signal processing routines which allow the manipulation of seismological time series (see Beyreuther et al. 2010, Megies et al. 2011, Krischer et al. 2015).
