One of the exciting developments at CCC last month was a talk discussing the copy protection features in the Wulim tablet produced by the Pyongyang Information Center. This post is an attempt to reconcile the features they describe with my experience with devices around Pyongyang and provide some additional context of the environment the device… Continue reading Thoughts on Wulim
Video from my CCC talk last week is here.

Third party analytics services are suffering from the growing prevalence of ad blocking, tracking protection, and the trend of minimizing connections and requests. However, from a site owner perspective, receiving usage information remains important for measuring site growth. My expectation is that we are already on the curve where ads and tracking software will be… Continue reading First-party Google Analytics

Proxy AutoConfig (PAC) is a mechanism used by many organizations to configure an advanced policy for connecting… Continue reading Watch your PAC

Network address translation (NAT) is a reality today for most Internet users, and poses a significant hurdle in creating the user-user (or peer-peer) connections. NAT is the process used by your router to provide multiple internal (192.168.x.x) addresses that are all only visible… Continue reading Stunning
Excited to see Satellite chosen as best student paper this year at USENIX ATC. Slides and audio from the talk should be online shortly.
The CS department, as always, is on top of its news releases.
I’m excited to present Satellite, a network measurement project I’ve been working on over the last couple years, at USENIX ATC next month. Satellite takes a look at understanding shared CDN behaviors and automatically detecting censorship by regularly querying open DNS resolvers around the world. For example, we can watch the trends in censorship in… Continue reading Satellite
