Title: Using Jupyter at Scale Within an Enterprise: 10,000 Users, 10,000 Notebooks

Speaker: Mr. Dave Stuart (US Department of Defense) 

The National Security Agency (NSA) has a large use-case for Jupyter. While traditionally known as a data science platform, we have worked to expand Jupyter's use within our organization to include our large user-base of intelligence analysts. These analysts, hard at work culling and correlating information from a multitude of repositories, are the domain experts who are closest to the analytic challenges we face. Jupyter has empowered this community - who do not traditionally come from software engineering backgrounds  - to translate their tradecraft into code, making that tradecraft more reproducible, more efficient, and more shareable.

The scale of our effort has forced us to address a number of challenges. With over a thousand Python authors, ten thousand notebooks, and ten thousand Jupyter users, we developed tools and approaches to manage, curate, and sustain crowd-sourced development of Jupyter notebook based analytics. We identified appropriate training paths to introduce Python and Jupyter into communities that most often lack prior backgrounds in coding. We outlined common use-cases for Jupyter, and worked to lower the barrier to entry to make the platform as approachable as possible. Most importantly, we ensured that all users of Jupyter within our Agency meet our strict data security and access controls.

This talk sheds light upon the secretive world of the NSA and shares some unique insight from our experience of adopting Jupyter across a large organization.  We will also detail how we are working to support the open source community surrounding Jupyter.

Biography Dave Stuart is a senior technical executive within the US Department of Defense, where he’s leading a large-scale effort to transform the workflows of thousands of enterprise business analysts through Jupyter and Python adoption, making tradecraft more efficient, shareable, and repeatable. Previously, Dave led multiple grassroots technology adoption efforts, developing innovative training methods that tangibly increased the technical proficiency of a large noncoding enterprise workforce.

MMM Seminar - Thursday, January 23, 2020 - 3:30pm

Speaker: Forrest J. Masters

Affiliation: University of Florida

The presentation will offer a forward-looking perspective that the civil (wind) engineering and atmospheric science fields are poised to reverse this trend by leveraging recent advancements in automation, data fusion and machine learning, heterogenous computing, multi-modal sensing, and other technologies reinventing modalities for scientific research and technology transfer. To build that case, we will begin by exploring the evolution of field reconnaissance efforts in landfalling Atlantic tropical cyclones to characterize the intensity and structure of damaging winds and how it is has influenced complementary research in atmospheric boundary layer wind tunnels (BLWTs). Key highlights will include activities and findings originating from the Florida Coastal Monitoring Program (which has led field experiments in 34 storms, including Harvey, Michael, and Dorian) and the Digital Hurricane Consortium, which represents the broader community of landfall experimentalists that deploy anemometry, mobile doppler radars, and storm surge/wave sensors.

The presentation will then explore cyber physical wind engineering experiments conducted in the NSF Natural Hazards Engineering Research Infrastructure (NHERI) BLWT using its computer-controlled terrain generator (the “Terraformer”) and other exciting new technologies that are reinventing the conventional design-build-test paradigm. Examples will include mechatronic building modeling to optimize the design of wind sensitive structures and the development of a new 300+ fan system to simulate non-stationary and non-neutral flows for the study of bluff-body aerodynamics in unsteady winds, flows over geomorphically complex terrain, and internal boundary layer formations. All systems are available for use by NCAR. Information will be given about how to access these resources as well as the lab/field data.

The presentation will conclude with remarks about how these research activities interrelate with the rapid transformation now taking place at engineering campuses worldwide, which is being driven by the so-called 4th Industrial Revolution (i.e., the integration of artificial intelligence, robotics, and the internet of things into industry and mainstream life), reduced barriers to adopt technology, and the emergence of student bodies that are increasingly more prepared for living and working in a “digital” world than previous generations. The perceived ripple effect on atmospheric science will then be discussed from an engineering perspective, with the goal of identifying opportunities in a future where data streams are sufficiently rich and forecasting tools are sufficiently skilled that the role of the “human in the loop” is far diminished by today’s standards.

Refreshments: 3:15 PM

Acrylic on Canvas by Monica Tymcio – Gallery I

Monica Tymcio’s paintings are a testimonial to her love of nature. She has spent the last 30 years living off-grid near the Indian Peaks Wilderness of Western Boulder County. It is here in this inspirational locale with her rescued horses, dogs and cats that she has made her home. She spends her time exploring the wilderness areas of Colorado on horseback, as well as backpacking in the remote canyons of Utah and New Mexico. Monica draws upon the deep sense of emotion she feels about a place or experience and then expresses that through her paintings to share with the viewer.

Fiber Art by Six Artists – Gallery II

Our love of fiber and its transformation through stitch, dye, paint, and print brought us together. Our varied voices, borne of differing life experiences, have inspired our conversations to connect literal and metaphorical threads and feed our self-expression.
