We investigate the problem of signing short messages using a scheme that minimizes the total length of the original message and the appended signature. This line of research was motivated by several postal services interested by stamping machines capable of producing digital signatures. Although several message recovery schemes exist, their security is questionable. This paper proposes variants...

Code clones, the result of the ”copy&paste” programming technique, have negative impact on software quality and on the efficiency of the software maintenance process. Although copying may be the fastest way of creating a new feature, after a while it is really hard to detect and maintain the multiple instances of the same code snippets. Based on static source code analysis, clone detectors try ...

The model explores how team production incentives ex post affect team formation decisions ex ante. In the game, one agent decides whether to share jurisdiction over a project with other agents.
