Oh cobblers! Unless you have a really crap client that's not a time
consuming thing to do. It's far quicker to switch over to the Fedora
folder to read all the new Fedora mail, minus the other stuff
interspersed.

Scrolling through an inbox with 300 new messages a day is time
consuming, finding the broken apart parts of threads is time consuming,
managing an inbox with 3479 messages sitting in is time consuming.

I, too, dislike the drive assignment shuffling. I really think that hda
ought to have been kept for IDE, sda for SCSI, and we should have used
some form of /dev/usb for USB. That way, you'd have clear and
unambiguous ways to address the hardware, where you expect to find it.
And you also have volume labelling for addressing some volume by name,
no matter where or how it's attached.

If you boot with your USB drives connected, but never boot *from* the
USB ports, you could try altering your BIOS booting arrangements, so
that it doesn't include the USB ports, or they're fallback rather than
early choices. You'd
 expect, this way, that they're looked at later on,
and the other drive gets the first designator (/dev/sda).

Ownership, not permissions.

On Windows, users Tim, Fred, and Barney save their files, and their
files are owned by themselves, with the Windows filing system knowing
the association between files and particular users.

Linux uses a different user identifier system. It can tell that *those*
Windows files are owned by three different people. But without some
mapping that says user 500 on Linux is Tim, and user X on Windows is the
same Tim, and so on for the other users, there isn't a way for each
users files to be owned
 by the same users on both systems.

Dismounting and remounting the drive with the next user owning all the
files is a mess, and useless for multi-user systems where there actually
are multiple users using it at the same time.

Removable media is a bigger pain. You can plug it into systems which
have completely different users.

Unless it was written 20+ years ago when /bin/sh used to exit on failed 
cd's unless in interactive mode. Now you need to
cd somewhere || exit
to avoid breakage.

I never run haldaemon and my system works fine. You need it if you 
want to mount a USB device (or other hotplugable device). When I need 
it, I start it, let it work and then stop it again. My computer is 
slow (PIII) so I need all the cycles for myself.

Here's all the daemons I run (this is a desktop, not a server).

No, link-local is the 169.254.x.y auto/random address scheme, for when
there's no DHCP server and the machines pick random unique addresses for
themselves, just so that they each have some IP address.

See: Bonjour or ZeroConf

It seems that Linux still has entries for it in the routing table, even
if you're not currently using that addressing scheme. It's probably
easier to leave them preset, so that no further configuration changes
need making should something connect up using one of those addresses, or
the local machine suddenly started using one, itself.

Only that *your* DNS server doesn't know anything about that address
(there was no "ANSWER SECTION").

This means nothing in the grand scheme of things (whether something is
using that address, or not). IPs don't have to be registered in a DNS
server.

I'd first check if it were the machine, itself, that was thinking that
IP was in use. Pull out the network cable, try "ifconfig eth0
192.168.1.6" (to manually assign that address to the box) and see if it
still protests that the address is in use while it's not
 connected to
any other equipment. If you get a complaint, now, you just have to fix
this machine, and you can ignore the rest of your network.

There's something vaguely familiar about this issue, with some sort of
phantom lingering about, but I can't recall the details. I can't recall
whether it was on this list, but searching through it for that error
message might be worth it.

The standard is a straight through cable for things that are supposed to
be connected together (e.g. computer to a switch or hub) and cross-overs
to things being directly connected together that would normally go
through something else (e.g. computers directly together).

I wouldn't expect any device to "expect" the wrong type of cable
according to the *usual* ways of cabling things. Quite a few things
will automatically accommodate using the wrong cable, but I wouldn't
expect that sort of behaviour.

Why should I care whether I read one
 fedora message, then a Centos 
message or 2 fedora messages in a row?

I rarely scroll anywhere - the new messages are on top and I read down, 
mostly deleting as I go. And my mail client will reassemble a thread 
in the rare case that there are earlier ones that I'd need to make sense 
out of the most recent. I want the mailer to bring the messages to me 
instead of me having to go find them.

The reason seems weak to me, but test does not

A lot of devices expect power from USB in a manner against the specs
(wanting too much current without specifically asking for it, or wanting
more than can be supplied, anyway). On some computers they'll
accommodate, others will not and you'll not get enough current to run
the device, and you can get random USB failures while you use your PC.

You can get 5 Volt plugpacks that have a female USB connector, and
that'll allow you to charge USB powered devices without a PC. If you're
just playing an Ipod, and rarely changing the contents, that's more
practical that running a PC just to charge its
 batteries.

You might want to tell the list exactly what model iPod you have.
Different models used different schemes. Some had Firewire and USB
connections, using one for power and one for data.

You could just have a broken cable. There's four wires in USB,
 two
power, two data. If a data wire broke but power didn't, you could see a
device turn on, but not actually be usable.

You could be trying to run it powered from your USB port where your USB
port isn't able to supply enough current (try going through a powered
hub, instead), you could have a wonky USB port on the computer (try a
different port - my computer's front-panel ports connect through crap
cables, they don't work well with high speed USB).
