The Stock-market Flash Crash: Attack, Bug, or Gamesmanship?
Andrew wrote last week about the stock market’s May 6 “flash crash”, and whether it might have been caused by a denial-of-service attack. He points to a detailed analysis by nanex.com that unpacks what happened and postulates a DoS attack as a likely cause. The nanex analysis is interesting and suggestive, but I see the…

On kids and social networking
Sunday’s New York Times has an article about cyber-bullying that’s currently #1 on their “most popular” list, so this is clearly a topic that many find close and interesting.

Did a denial-of-service attack cause the stock-market "flash crash?"

What has surprised me, though, is how rarely anyone explains the rationale behind soccer’s…

Rebooting the CS Publication Process
The job of an academic is to conduct research, and that means publishing manuscripts for the world to read. Computer science is somewhat unusual, among the other disciplines in science and engineering, in that our primary research output goes to highly competitive conferences rather than journals. Acceptance rates at the “top” conferences are often 15%…

NJ Voting Machines Left Unattended, Despite Court Opinion
It’s Election Day in New Jersey. Longtime readers know that in advance of elections I visit polling places in Princeton, looking for voting machines left unattended, where they are vulnerable to tampering. In the past I have always found unattended machines in multiple polling places. I hoped this time would be different, given that Judge…
