Ryan Rohm

Ryan Milton Rohm (born 22 December 1957, Gastonia, North Carolina) is an American string theorist. He is one of four physicists known as the Princeton string quartet,[1] and is responsible for the development of heterotic string theory along with David Gross, Jeffrey A. Harvey and Emil Martinec,[1][2][3] the other members of the Princeton String Quartet.

Rohm studied physics and mathematics at North Carolina State University (NCSU) with bachelor's degree in 1980 and received a Ph.D. in physics from Princeton University in 1985. He was a postdoc from 1985 to 1988 at Caltech. From 1988 to 1995 he was an assistant professor at Boston University. In 1997 he earned a master's degree in computer science at NCSU. Since 1998 he has worked on experimental neutrino physics in the KamLAND experiment and at the Triangle Universities Nuclear Laboratory (TUNL). Since 1997 he has also been an adjunct professor at the University of North Carolina at Chapel Hill.[4]

Selected publications

gollark: Oh, so you mean this `hdr` goes at the start and the `dofs` thing tells you where the bit appended to the end is?
gollark: Perhaps the headers should also store the location of the last header, in case of [DATA EXPUNGED].
gollark: There are some important considerations here: it should be able to deal with damaged/partial files, encryption would be nice to have (it would probably work to just run it through authenticated AES-whatever when writing), adding new files shouldn't require tons of seeking, and it might be necessary to store backups on FAT32 disks so maybe it needs to be able of using multiple files somehow.
gollark: Hmm, so, designoidal idea:- files have the following metadata: filename, last modified time, maybe permissions (I may not actually need this), size, checksum, flags (in case I need this later; probably just compression format?)- each version of a file in an archive has this metadata in front of it- when all the files in some set of data are archived, a header gets written to the end with all the file metadata plus positions- when backup is rerun, the systemâ„¢ just checks the last modified time of everything and sees if its local copies are newer, and if so appends them to the end; when it is done a new header is added containing all the files- when a backup needs to be extracted, it just reads the end and decompresses stuff at the right offset
gollark: I don't know what you mean "dofs", data offsets?
