What do I get out of conferences?

Some of the events were paid by work, some were paid[…]

Presenting at Johnson Space Center Data Science Day

This week I presented on the last 40 years of digital data visualization tools at Johnson Space Center Data Science Day. The event was held just off site this year, so it could be opened up to the public. The talk was a condensed, and I think improved, version of a talk I had previous gave[…]

Raspberry Shake – Personal Seismometer

Sometimes I get to combine geology nerdiness with technology nerdiness. This post definitely falls into that category. Earlier this year, I contributed to a kickstarter campaign by Ángel Rodríguez that raised $99,258 to bring into existence an inexpensive short period seismometer produced by OSAP. It consists of programs running on the Raspberry Pi, a small board that sits on top of[…]

“THE CHANGING LANDSCAPE OF DATA VISUALIZATION TOOLS IN LARGE ORGANIZATIONS”I recently gave a talk at the Houston Data Visualization meet-up. In addition to being a good excuse for putting time on my calendar to research the evolution of data visualization tools over the past 40 years, the talk allowed me to try out a few presentation[…]

Flow Chart for Picking the Right Mapping Tool

I did some research on different tools for creating flow charts today.Originally, I started down this path trying to figure out what open-source project I might be able to hack on and produce a project that would generate XKCD style flow charts, similar to how bokeh (python library) has XCKD style plots as built-in option. I[…]

Reproducibility in Code and Science

This week SciPy 2016 took place in Austin. I didn’t attend. However, the conference produced a lot of really interesting conversation and sharing of links to talks on youtube on two different slack channels I follow.One of the themes that stood out was reproducibility. A good introduction to the problem of reproducibility is point 3[…]

Gource – Log Visualization Tool

At work, I put projects I complete into our group’s gallery of data-visualization work. It is good internal marketing for what our group can deliver. Unfortunately, even behind a NASA firewall, there are some things I can’t put in the gallery. Examples have included data visualizations of human resource data and financial data where the public[…]

ISS Fly Over

ISS = International Space StationEarlier this week someone came into my office at work and asked to borrow three of our beanbags, so they could have recently returned astronauts sit in them while doing a facebook live-stream event.
