Yeah, some of the answers it produces are very questionable. The implementation of a lot of the stat functions is super-naive and not very stable in borderline cases. Take the standard deviation of three identical numbers, get an answer which is nearly-but-not-quite zero. They’ve also refused to improve their algorithms as it might break existing customer worksheets.

A CD with RedHat on it? Pretty fancy. My first RH installation came on about three boxes of floppy disks, took hours to unpack it all. And damn right, been all uphill since.
