According to the French National Railroad Company (SNCF) the testing campaign will continue and speeds up to 570 km/h (354 mph) could be atteigned by June of this year.

Submission + - Deputy: Type and Memory Safety for C Programs

Submitted by Anonymous Coward on Wednesday February 14, 2007 @04:33AM

An anonymous reader writes: Deputy is a C compiler built by researchers at UC Berkeley that uses simple programmer-supplied annotations to catch type and memory errors such as buffer overflows and misuse of union types. For example, if you write a function that takes a buffer and its length as arguments, you can annotate the buffer's type to indicate that its length is stored in the second argument. Using these annotations, Deputy will either verify accesses to this buffer at compile time or insert the required run-time checks. Deputy has already been used on several Linux device drivers and has a corresponding recovery system for Linux called SafeDrive.
