After a long hiatus, Mark Krenz will be giving a presentation on how
to use screen to manage your terminal windows effectively. He also will
demonstrate how to use the vi editor, specifically, the vim flavor of
it. Mark uses these programs daily at work and home (and to write this
email) and has a lot of tips and tricks for both programs.

Come join us for the meeting and chat with other Linux users before

I've grown frustrated with load average because of things like this.
I've seen systems stop sending email and such because of some
side-process having to wait for disk IO or something, and then the
machine stops processing email because the load goes above 10 or
whatever, even though everything is running smoothly. After 35 odd
years of unix, you'd think they'd have some other means of gauging how
busy a system is. Do they?

Yeah, great story: "uh, I was doing something I can't talk about, and
it drove the load up real high!". :)

Actually, I think 42 was meant as more of a joke than it seemed. I've
never read the book (shame on me) but I have a sysadmin of the year
t-shirt (No, I wasn't sysadmin of the year) that has the 101010 on the
front of it and its meant to mean that sysadmins could read the shirt
and thus have answer to life the universe and everything.

But 101010 is a number that looks kinda erroneous, like there was an
error. Perhaps it was meant to signify that after spending thousands of
years, the computer just had an error and they interpreted it to be 42.
Ok, I've been thinking about this too much, get back to work.

Mark secretly works for the NSA. They've set up a secret room at his
place of employment and they've tapped the fiber at the Telco Hotel and
are splitting it off to Mark's work. There's a cluster of Linux boxes
doing deep packet inspection on all the traffic. The huge spikes this
morning are because all the students are back and the freshmen -- not
used to all the available bandwidth -- are now happily downloading all
the {music,videos,pr0n} they can.

I feel like someone who has a big secret and tells people that they
have a big secret but that they can't tell anyone. Needless to say I
can't tell you exactly, but it wasn't CPU bound, it was disk io waits.
So not real load. The system was still pretty responsive. Its back
under control now. Great way to start the week though. And a good

Its not actually a float -- you can't use floating point in the kernel,
so its probably just scaled, using 1024 as its base...

In any case, that is a big number. What exactly is that machine doing?

Wow, I think the highest I ever saw the load on a machine go up until
this point was 350 or so. I've never even heard of 4 figure load
averages. It seems to reset the number after 1024 (2**10). But its

Actually, I have a log that keeps track of it and this is actually the

Actually, the 15 minute load average went over 3 times, the 1 minute
load average has gone over 14 times. So its over 14,000 now.
