    I've made significant revisions to my paper about the security properties of BMDs and how to conduct live audits. The math shows that auditing costs for useful bounds on tampering are quite reasonable.

    Here's our story about the Iowa caucus app meltdown, with analysis from and about why this matters for election security and what it says about the IDP's preparations.

    So far as we know, this was a failure of aggregating the local numbers, but all the raw data are still out there -- handwritten tallies. Post mortem of the app, including the processes for its procurement and testing, will be illuminating.

    Not only are these policies an affront to academic freedom, and not only are they unlikely to achieve any meaningful policy objective, but they're also a huge deterrent to Australian universities' faculty recruiting. So, huge net loss for the country.

    My mobile phone number is edit-distance 4 away from a number being promoted by a beer vendor for some interactive thing. I'm getting a pile of wrong numbers dialed. I can only imagine how much fun this is for people with closer phone numbers.

    Hi folks. As you may have heard, I have been fortunate enough to work with amazing people and put out a study about ballot-marking devices. You can read it here:

    I'm looking forward to building some really great voting technology this year.

    This is an important human participant study of voters' ability to detect errors on BMD printed ballots. The punchline is that you need to specifically prompt the voters to check. “Have you carefully reviewed each selection on your printed ballot?”

    If anybody's curious, here's a YouTube screencast lecture for my Comp215 class on binary heaps and sorting. Classes were canceled today at Rice due to Tropical Storm Imelda.

    Hey , your web site offered me a great $90/mo plan upgrade. I clicked it, and the billing for the new plan is $140/mo instead of $90/mo. Nobody I can get on the phone or chat seems able to honor the price your own web site offered to me. How do I get this fixed?

    This is absolutely amazing. I need to play with the tool itself, but the user manual is a pleasure to read. The fundamental goal is laudable: a crypto-protocol verification tool explicitly engineered for ease of use and legibility of results.

    There's a debate among election experts: are electronic ballot marking devices secure? Appel, DeMillo, and Stark argued that BMDs could silently cheat voters. I've written a response that considers reasonable mitigations as well as the benefits of BMDs.

    Do I know anybody who works at / ? After my fancy bike got stolen from the place I was renting, I got an email from "Airbnb Community Support" with a case number, but I've gotten zero followup despite several emails.

    I gave a keynote talk at today's EPFL "IC Research Day". My talk was broad overview of all things related to voting security (social media fake news, voting machine insecurity, Internet voting, hand-marked vs. machine-marked paper, and more).
