This year, the voting process for the Oscars has changed. Rather than indicating a single choice as they have done since 1946, members of the Academy will provide a first choice, a second choice, etc.. potentially ranking all 10 nominees for Best Picture if so desired. Some are speculating that this will affect the results. [...]

I was speaking with a colleague yesterday about Loopt, the location-based social network, the rise of location-based services and the incredible privacy challenges they present. I heard the Loopt folks give a talk a few months ago, and I was generally impressed with the measures they’re taking to protect their users’ data.

Well, it’s been a few weeks of craziness at home and catching up on other work, but I’ve finally wrapped up the Takoma Park 2009 audit. The final step: letting you, dear reader, run the audit all on your own.

Let’s say someone’s trying to sell you a house. It’s a beautiful house. You visit it. You have it inspected and re-inspected, and it’s perfect. You get a loan approved, and you’re about to sign the papers when you’re told: wait, actually, that house is no longer available, but why don’t you just sign [...]

We’ll now consider the auditing portion of the Takoma Park election. This is a little bit involved, so we’ll take our time. Importantly, the typical voter does not need to burden themselves with this complexity. All that Valerie, our voter, needs to do, [...]
