At the end of last month, Seattle posted a request for information exploring the feasibility of a municipal Wireless deployment. With others at the Seattle Privacy Coalition, I draft a response to the city flagging some of the major privacy issues that we hope they will consider in the initiative. I believe these are much… Continue reading Privacy issues for City Wi-Fi Deployments
I wanted to try to put into words part of what I appreciate about community, through a description of one of the more unique communities I’ve visited: Slab City.
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
About five years ago two projects, Zmap and Masscan, helped to shift the way that many researchers thought about the Internet. The tools both provide a relatively optimized code path for sending packets and collecting replies, and allow a researcher with moderate resources to attempt connections to every computer on the IPv4 Internet in about… Continue reading Thoughts on IPv6 Measurement

Notably, when considering the impact on… Continue reading Thoughts on China’s Updated Cyber-security Regulations
A topic of conversation recently has focused on the practicality of Decimal time. Days would have 10 hours, each with 100 minutes. I recently completed a side project of converting an old clock to use decimal time. (If you aren’t willing to switch to decimal time fully, there’s an web version as well.)
I’m getting back this week after spending most of the last month Bicycling from Pakistan to China on the Karakoram highway. It was a great trip, full of friendly people, breathtaking mountains, and delicious food.
In the last week at Blackhat / Defcon two groups looked deeply at one of the lesser known implementations of network policy called Proxy Autoconfig. (In particular, badWPAD by Maxim and Crippling HTTPS with unholy PAC by Safebreach.) Proxy AutoConfig (PAC) is a mechanism used by many organizations to configure an advanced policy for connecting… Continue reading Watch your PAC
