Open Source Club

at The Ohio State University

The Open Source Club at the Ohio State University is a registered student organization composed of members from all around campus and out into the community who share a common enthusiasm for free, open source software. Our focus is on building a strong community of open source users and developers in order to bring the benefits of open development, open standards, and free software to the university community.

Neural Networks and Deep Learning with Capital One

posted: 02-22-2017

Deep learning has become one of the hottest topics in computing in the past few years. Neural networks are not a new topic, but with the recent advances in computation capacity provided by hardware accelerators, in particular GPUs, they have gained new popularity. In this talk we present some of the concepts behind neural networks and deep learning, and then shift to the performance aspects of available solutions. We will finally focus on Tensorflow, an open source deep learning package, and provide a hands-on demo using it.

Bio- Reza Farivar is a manager at the Data Intelligence team in Capital One. He received his Ph.D. in Electrical and Computer Engineering from the University of Illinois at Urbana Champaign, working on Big Data, Clouds and Machine Learning pipeline engineering. His Postdoctoral work was on development of GPU-based learning algorithms for bioinformatics. His current work focuses on fast data streaming systems and distributed algorithms for Big Data learning and Cloud systems. He is also an adjunct assistant professor at the computer science department at the University of Illinois at Urbana-Champaign, where he teaches topics related to cloud computing and big data applications, spanning from batch and real-time processing to deep-learning and graph-based systems.

Join us tomorrow, Thursday February 23rd at 19:00 to learn about machine learning from Reza Farivar of Capital One and some of his team. As always laptops are encouraged, and there will be pizza which is provided by Capital One this week.

Idiomatic Python

posted: 02-03-2017

Join us Thursday February 9th, 2017 at 19:00 as Brian Costlow, a PyOhio board member and previous conference chair, presents on Python. A summary from Brian Costlow:

Idiomatic Python

All languages, even programming languages, develop idioms. Python is such a flexible language that newcomers to the language sometimes end up writing “C in Python” or “Java in Python”. This talk will cover some common pitfalls where there is more than one way to do it, and show you which one a seasoned Pythonista would reach for. Along the way, we’ll talk about iterators, generators, data structures, comprehensions and more.

As always there will be pizza, and laptops are encouraged!

Join us Thursday January 26th at 19:00 in Caldwell 120 as Professor DK Panda, a distinguished scholar of the CSE department and member of the Network-Based Computing Laboratory at OSU.

The Network-Based Computing Laboratory at OSU/CSE in actively engaged in designing software libraries for supercomputers. The open-source MVAPICH software project at OSU/CSE has been enabling MPI libraries for TOP supercomputers in the World (including the latest #1st ranked) during the last decade. The group is also involved in designing High-Performance Big Data libraries for Hadoop, Spark and Memcached, and are focused on High-Performance Deep Learning such as Caffe and CNTK. This talk will provide an overview of these projects. It will also provide an outline of the associated research, publications, designs, testing and support framework for these libraries. Opportunities for students to get involved in the R&D activities in these projects will be outlined. The talk will follow with an open Q&A session with several members of the Network-Based Computing Laboratory. The session will conclude with a tour of the Laboratory consisting of multiple high-end clusters involving thousands of cores.

Pizza will be provided by the Network-Based Computing Laboratory, and as always laptops are encouraged.

Von Neumann machines

posted: 11-30-2016

Join us this Thursday as Jon Arnett presents on Von Neumann machines and to say goodbye to our graduating seniors. The following is a brief excerpt on Von Neumann machines from Jon Arnett:

“Imagine a probe gliding through the galaxy. It lands on a planet, and begins to mine. After a while, it uses the materials it has collected to construct a replica of itself. The replica launches into space. The original probe sets off to explore its new found world, sending data back to Earth.

Imagine a nanobot breathing in carbon dioxide and breathing out oxygen. Overwhelmed by the sheer amount of gas it must convert, it creates a replica to help it create a breathable atmosphere.

Imagine a world that’s gray. It undulates, slightly. If you were to take a microscope and look very closely (cautiously, though), you would see a teeming civilization of nanobots. They have overrun. They have eaten everything. They will eat you, too, if you get too close.

These are the promises and perils of Von Neumann (or Self-Replicating) machines. Join me for my exploration of this field, focusing on the history and theory of such machines.”

As always there will be pizza and laptops are encouraged.


Wikipedia in your next project

PGP KeySigning Party

posted: 10-17-2016

Pretty Good Privacy(PGP) is a great way to communicate privately, but also to verify the identity of an online source. PGP is commonly used in fields such as journalism when identity is a must or when signing your code. PGP can also be used to encrypt communications so that only one party can read it.

Join us this Thursday, October 20, 2016, as Michael Yanovich describes the functionality of PGP and demonstrates how to use it. You’ll learn how to generate your own key, and have the opportunity to partake in a key signing party!
