Actually, Grex runs faster for people who are listed early in the password
file, not for people with low UID numbers. That is, if we added someone with
UID 65 at the end of the /etc/passwd file, even though 65 is low, things would
run slowly for them. What slows things down is the programs that have to scan
through /etc/passwd line by line looking for a user.
A huge percentage of all accounts created are reaped. This means that if you
stick around for a while, people who are ahead of you in /etc/passwd are
deleted, so your account gets closer to the beginning of the file. The closer
you are to the beginning, the faster certain programs run.
Other programs are linked with the "shadow password libraries" and use an
index to find people in /etc/passwd. Those programs run fast for everybody.

Ryan, don't scream at me. I *know* ICNET is what grex uses. We, however,
dial into MichNet and *telnet* to Grex. So if MichNet is running slow, it's
not Grex's fault. *That's* what I meant by my response. I was referring to
a friend ofmine who dialed into the Gaylord Library, telnetted to M-Net, from
there to nethernet, and from nethernet to Grex. She couldn't figure out why
it was slow 'til I told her she was thrice telnetted.

Screaming at you? What would give you that impression? By the
way I read your response, it sounded like you thought grex got it's
connection from MichNet.

Well, for a minute it sounded like you were using extreme sarcasm to make me
look stupid...one of my *biggest* pet peeves. I reread the response you
reread, and it *did* look like I thought Grex was hooked to MichNet...so I
apologize for being ambiguous. That's also why I clarified myself later.
<smile> Intonation on line can be soooo tricky.

The copy of PicoSpan on the sun-4 is linked with code that knows about
the dbm files and should run fast for everyone, regardless of where they
are in the password file.

Ah. Thank you, Rob. 7067. Not too bad.

I really do believe that the lag on our line is usually much more intimidating
than our load average. I telnet in a lot, so I know how bad the lag is.
I also seriously doubt that Michnet's delays ever add up to more than a drop
in the ocean of Grex's link delays.

Unless you get your access from MichNet like i do! <G> I have to
go thru MichNet to get anywhere, blech.

Well, I wasn't implying anything positive or negative about the suitability
of MichNet for accessing other sites.

Merit (I's assuming that's part of michnet?) has always been good for me.

Yes, I think Michnet is a "division" of Merit. (or something like that)
And for me, MichNet has constant network freezes, and now they just
implied two new rules for access which I do not like at all.
These were not stated before I got my account, and were implied without
warning.

I believe Michnet is the system operated by the corporation known as Merit
Network, Inc. Merit started out as a group of radical acadamicians and secret
government agent whow set up a method of communicating among colleges and
research centers using coded carillon signals. Institutions with the biggest
towers got the most funding and Merit was born at UM. Well, it was something
like that.

There are bizarre and unpleasent problems all over the net these
days. That Michnet might be doing things to Ryan I have no doubt of--
during peak periods I've been T3 connected hosts FTP data to each other
at 2K/second, rather than the more typical 200K - 300K second.

It's no doubt that the internet is seriously overloaded. Many people predict
a crash in the near future that may kill it completely. I happen to disagree,
but...

It can't "die"--it will just get slower and slower. Unforunately
we haven't seen the worst of the slownss, either.
When ATM comes about and we start seeing segments of the backbones
performing much more acceptably we'll then see people screaming for
their backbone sections to be upgraded and eventually we'll have a
fast net again. But right now, this T3 stuff just isn't good enough.
What was great 4 years ago reeks today...

Software bloat. In this case, theWeb, and graphics for everybody.

If the speed doesn't suck, add more whistles until it does, then shell out
the big bucks for more/faster hardware.

Exactly. Thank you Grex for not contributing tonet bloat. :) I'm grateful
that I can still do most of my net work (pun intended... :) ontext based
connections, and that the majority of my web based stuff is done on UM's
ethernets.

(Kinda hard when the response of every prof is "Check the class web page")

Wow... When I was a student, the new rage was to have a class conference for
each class. Do they still have those, or do most classes now have only the
much more one-way communication of web pages?

We have class newsgroups now, as well as web pages. I've heard of one prof
thinking about a class conference, but I have no idea where or how to get to
such a conference even if it were to be made.

I have class conferences on Confer-U for a senioror laboratory course, to
permit teams to communicate on their projects and all the students in all the
teams to stay aware and contribute to all of the projects. It does not work
as well as I would like, but because of the unwillingness of students to
"stick their necks out" even in an engineering discussion.

Weird. People did plenty of sticking their necks out, and plenty of good
conferencing, in the class conferences I participated in way back when.
If you haven't already done it, maybe it would help if you stuck your own neck
out, to set the tone? (Just guessing -- I haven't been in Rane's class
conferences to see what they're like, so I could be *way* off here.)

I do participate actively. However the discussions are not primarily
opinions or alternative interpretations. These are engineering projects,
so while there are alternatives to discuss, they ought to be *correct*
alternatives. The students are afraid of making "dumb" proposals, so
mostly don't make any at all. (and conseqeuntly make poor progress on
their projects).
