miscellany: e-Business done

Finished up e-Business; turns out no writing was required, as two versions of the course exist. I received the new course, but the old book; after completing two of the assignments, then asking about the discrepancies between course material and supplied text, was given the old course materials.

Also finished up the work for the forensics class.

Last stop, a project of some kind. I may possibly have worked out the bit where one part of a ciphertext must successfully be decrypted to yield part of the key needed to decrypt the following part; need to test a bit.
