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 and let someone else deal with the fallout.

Monthly updates since 2008

Civic projects

EMCCC, PA

Eastern Montgomery County Chamber of Commerce, PA, 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 Public Access File

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.
