One area would be in University Operating Systems courses - it would again be possible to offer practical coursework on operating systems that are comprehendable in their entirety (ala V6 and Minix). --=20 Peter Jeremy --82I3+IH0IqGh5yIs Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEARECAAYFAkoVzRUACgkQ/opHv/APuIfQCwCeLwqoTwMdt0p5z86D/NoP5mPA jtwAnAoIbSA3YzF816uP5rWrkMcTG0CN =OdBk -----END PGP SIGNATURE----- --82I3+IH0IqGh5yIs--
