Formal verification of a memory model for C-like imperative languages
http://www.springer.com/International audienceThis paper presents a formal verification with the Coq proof assistant of a memory model for C-like imperative languages. This model defines the memory layout and the operations that manage the memory. The model has been specified at two levels of abstraction and implemented as part of an ongoing certification in Coq of a moderately-optimising C compiler. Many properties of the memory have been verified in the specification. They facilitate the definition of precise formal semantics of C pointers. A certified OCaml code implementing the memory model has been automatically extracted from the specifications

Phalloid Fungi in Hawaii
The order Phallales, as outlined by Cunningham
(1942) and Zeller (1949), contains three
families and approximately 20 genera of fleshy
basidiomycetes, which, because of their usually
stalked fruiting bodies and foetid odor, are
commonly called "the stinkhorns." The group
includes some of the most bizarre and unusual
of the fungi
