Awareness and merge conflicts in distributed development (new paper)






How can we make sure that people are aware of each other’s changes to a shared software base? Iin particular, can we avoid the dreaded case of a merge conflict: you and I are working on the same piece of code, but we find out too late, and we have to undergo the painful process of reconciling our conflicting changes.







Framing the frame problem (new paper)






Among the open problems of verification, particularly the verification of object-oriented programs, one of the most vexing is framing: how to specify and verify what programs element do not change. Continuing previous work, this article presents a “double frame inference” method, automatic on both sides the specification and verification sides. There is no need to … Read more




Detecting deadlock automatically? (New paper)






To verify sequential programs, we have to prove that they do the right thing, but also that they do it within our lifetime — that they terminate. The termination problem is considerably harder with concurrent programs, since they add a new form of non-termination: deadlock. A set of concurrent processes or threads will deadlock if … Read more

A gold medal






The French National Research Center (CNRS) has just awarded [1] its annual gold medal to Gérard Berry, a great recognition for an outstanding computer scientist. I first discovered Berry’s work through a brilliant 1976 article, Bottom-Up Computation of Recursive Programs [2], which explained recursion using methods of denotational semantics, and should really figure in collections … Read more
