What's hot

Pacific Medical Training

We employ thousands of workers in entry-level medical jobs. We are also the world's first company to release CPR and advanced life support training courses when new science guidelines are published.

General manager since 2013



This project helps the US Department of Defense share more computer science projects with the public by helping its project managers set code release policies.

Contributor since 2017

Civic projects


Eastern Montgomery County Chamber of Commerce, PA, co-chair government affairs committee board. We work with local, state and federal government representatives to connect local businesses with elected officials.

SEPTA rail scheduling

I consult with SEPTA to help set their rail schedules. Also, I independently measure On-Time Performance of all SEPTA trains. If you are ever late for work because of a late train, use my website as proof so you have an excuse.

Philadelphia Traffic Court

Philadelphia Traffic Court made national headlines throughout 2014 as its offices were raided by the FBI and 9 current and former judges face indictments on 77 counts. I successfully petitioned the Philadelphia government to make public their entire database of traffic violations. Now lawyers use it to appeal old tickets and some people have used the data to find evidence of wrongdoing.

More products and research

Digital security blog

If you are alive today then information about you is you probably being collected and used in ways you don't appreciate. I work with the FBI, Apple and others to solve problems. Or sometimes I just publish live exploits and let someone else deal with the fallout.

Monthly updates since 2008

Personal blog

With analysis of football betting marketing inefficiencies, sentiment during the great depression, facial hair correlation to economic activity, and much musing.
