Operating Systems Accomplishment | 1990
IBM researcher: Marc Auslander
Where the work was done: IBM T.J. Watson Research Center
What we accomplished: Adapted from Wikipedia: "A journaling file system is a file system that keeps track of changes not yet committed to the file system's main part by recording the intentions of such changes in a data structure known as a "journal," which is usually a circular log. In the event of a system crash or power failure, such file systems can be brought back online more quickly with lower likelihood of becoming corrupted."
