Privacy Log

I perform technical research of smart contracts and websites. This includes work
with the FBI and Apple. Usually I publish these on Privacy Log, and sometimes
these publications are live zero-days if the vendor failed to take corrective
action. (Of course, I never post zero-days against advisory clients.)

Recent zero-days:

 * GitHub Pages: anyone can publish to your site live
 * Compound Finance: prices can move faster than advertised CVE-2019-20809

Monthly updates since 2008

   exhaustive-search problems, this is one effort in that direction, Google
   Groups post

   way to calculate entropy, and necessary for my 19q game. Related:
   https://en.wikipedia.org/wiki/Perplexity

   exam

More music:

 * Only (and music video)-- my award winning remix of Nine Inch Nails's song. I

   album.

   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. Patent application.
 * 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.
