In this article, we determine the number of yes/no questions required to figure out a birthday (a number between 0 and 31) when up to r incorrect answers to these questions are allowed. In the language of error-correcting codes, we construct optimal (shortest possible length) codes of size 32 and minimal distance d for each positive integer d .

Videotape has become one of the CHI community's most useful technologies: it allows us to analyze users' interactions with computers, prototype new interfaces, and present the results of our research and technical innovations to others. But video is a double-edged sword. It is often misused, however unintentionally. How can we use it well, without compromising our integrity? This paper presents...

This paper studies a model of strategic communication by an informed and upwardly biased sender to one or more receivers. Applications include situations in which (i) it is costly for the sender to misrepresent information, due to legal, technological, or moral constraints, or (ii) receivers may be credulous and blindly believe the sender’s recommendation. In contrast to the predictions obtaine...

We present Catena, an efficiently-verifiable Bitcoin witnessing scheme. Catena enables any number of thin clients, such as mobile phones, to efficiently agree on a log of applicationspecific statements managed by an adversarial server. Catena implements a log as an OP_RETURN transaction chain and prevents forks in the log by leveraging Bitcoin’s security against double spends. Specifically, if ...

We prove that the three-sphere recognition problem lies in NP. Rubinstein [Haifa, 1992] and Thompson [Math. Res. Let., 1994] showed that the problem is decidable. Our result relies on Casson’s version [MSRI, 1997] of their algorithm and recent results of Agol, Hass, and Thurston [STOC, 2002].
