Never used dos. Color Computers with os9, adding amigados, then linux
from 1998. And the color computer is running right now. os9, now Nitros9
is a unix like but no security other than a login password if coming in
thru an rs232 connection.

All of which to me are not progress but bloat, slowing the machine. OTOH
I am the only user here, and finding I have to sudo before I can run
something just to check/read something, AND have to have the path to it
memorized because like you, whats a cgroup? ACL's I might get used to,
but more and more its all a PIMA, often caused by pam and its poor to
non-existant docs, but its damned sure keeping me from doing something
I've been doing since my first red hat 5.0 install. For instance I can
ssh -Y from this wheezy box to any other wheezy box w/o a problem, but I
have yet to find the magic twanger to make it Just Work to a jessie or
stretch install. Then someone else has decreed there is no network until
a user has logged in from the machines own keyboard. Someone has
decided its a security hole without understanding that they are making
life a cast iron bitch for someone like you or me.

The latter is not teaching CS, its teaching how to be dumb users, which
to me is no better that mom & pop buying them a lappy and a net cable,
they can learn that on their own, while letting a virus removal shop
make a good living.

Which is good on the face of it, but those web sites change addresses
weekly, so its a lost cause, your 10 year old IS gonna find the porno.
Changes in how his/her body acts is something the parents seem to have
abdicated the explanation of such to the child, and that is a parental
duty whether you have cows and pigs in the barn, and chickens in the
yard, or are in the middle of star city.
