Facebook intern graphs the scope of the business, connections

Ever wonder what your interns are doing for you and your business? If it’s anything like Facebook’s data infrastructure engineering intern Paul Butler, then he or she is most likely working on showing the spread and significance of your brand and its worth. Butler created a Facebook social graph that shows the locations of friendships around the world by correlating the longitude and latitude of 10 million friend pairs. He used the sample to mark the current cities of the friend pairs to show the magnitude of Facebook reaching out to the whole world.

The visualization shows that the U.S. has the highest concentration of Facebook friendships and Africa has the lowest. In a Facebook note, Butler writes: 

“When the data is the social graph of 500 million people, there are a lot of lenses through which you can view it. One that piqued my curiosity was the locality of friendship. I was interested in seeing how geography and political borders affected where people lived relative to their friends. I wanted a visualization that would show which cities had a lot of friendships between them….

“At that point, I began exploring it in R, an open-source statistics environment. As a sanity check, I plotted points at some of the latitude and longitude coordinates. To my relief, what I saw was roughly an outline of the world. Next I erased the dots and plotted lines between the points. After a few minutes of rendering, a big white blob appeared in the center of the map. Some of the outer edges of the blob vaguely resembled the continents, but it was clear that I had too much data to get interesting results just by drawing lines. I thought that making the lines semi-transparent would do the trick, but I quickly realized that my graphing environment couldn't handle enough shades of color for it to work the way I wanted.”

Not only is the social graph a visually pleasing image, but it shows the impact that Facebook really has when it comes to connecting friends, family, businesses, and beyond, across borders, oceans and political issues. If Butler doesn’t get hired on by the Facebook engineer team, we’re pretty sure he’ll make his mark with another promising corporation.

Dark Wolf: accelerating security for USAF

Dark Wolf Solutions is small and agile, its partnership with the US Air Force is helping to deliver critical security faster and better than ever before

As a small company whose biggest customers are the Department of Defense and the Intelligence Community, Dark Wolf Solutions (Dark Wolf) is a triple-threat, specializing in Cybersecurity, Software and DevOps, and Management Solutions. Dark Wolf secures and tests cloud platforms, develops and deploys applications, and offers consultancy services performing system engineering, system integration, and mission support.

The break for Dark Wolf came when the Department of Defense decided to explore software factories. Rick Tossavainen, Dark Wolf’s CEO, thinks it was an inspired path for the DoD to take. “It was a really great decision,” he says, “Let’s pull our people together as part of this digital transformation and recreate what Silicon Valley startup firms typically have. Let’s get into commercial facilities where we have open windows and big whiteboards and just promote ideation and collaboration. And it creates this collaborative environment where people start creating things much more rapidly than before.”

It has been, Tossavainen says, “amazing to watch” and has energized the Federal Contracting Sector with an influx of new talent and improved working environments that foster creativity and innovative ways of approaching traditional problems.

“We originally started working with the US Air Force about three years ago. The problem was at the time you could develop all the software you wanted but you couldn’t get it into production – you had to go through the traditional assessment and authorization process. I talked to Lauren Knausenberger and she told me about Kessel Run and what eventually came out of this was the DoD’s first continuous ATO [Authority To Operate].”

The secret to Dark Wolf’s success – and its partnerships with USAF and Space Force – lies in a client-first attitude. “We’re not looking to maximise revenue,” Tossavainen explains. “We tell all of our employees, if you’re ever faced with an issue and you don’t know how to resolve it, and one solution is better for the customer and the second is better for Dark Wolf, you always do number one. We’ve just got to take care of our customers, and I look for other partners that want to do that. And let’s work together so that we can bring them the best answer we can.”

Rapid releases and constant evolution of software are common themes among USAF’s partners. Like many firms operating in the commercial and public sector spaces, Dark Wolf leads with a DevSecOps approach.

“Failure is tolerated,” says Tossavainen. “If it’s not going the right way in three months, let’s adjust. Let’s rapidly change course. And you can tell really quickly if something’s going to be successful or not, because they’re doing deployments multiple times a day – to the customer.”
