We all learned in science class that water freezes at 0 °C or 32 °F at atmospheric pressure. But what water, exactly? Even after you distill out all the dissolved salts and minerals to get pure H2O…
When I was 5, I saw the Karate Kid. I saw that bad guys could beat me up, and I had no recourse if I didn't know karate. I promptly signed up for martial arts classes.
Abstract: Cryptography rearranges power: it configures who can do what, from what. This makes cryptography an inherently political tool, and it confers on the field an intrinsically moral dimension. The Snowden revelations motivate a reassessment of the political and moral positioning of cryptography. They lead one to…
I grew up on a farm outside of a rural town about an hour southeast of Columbus, Ohio. Like many small towns in America, my town knows “brain drain” – all of my friends from high school who went to college (~30% of my class) now live elsewhere, although most are pretty close by (e.g., several live in the suburbs of…

After years of battles over Bills C-11 and C-18, few Canadians will have the appetite for yet another troubling Internet bill. But given a bill that envisions government-backed censorship, mandates age verification to use search engines or social media sites, and creates a framework for court-ordered website blocking…
Persuasion is as old as our species. Both democracy and the market economy depend on it. Politicians persuade citizens to vote for them, or to support different policy positions.
