You are not going to turn Peter Breuer into a hand holding softee.
Let's just be thankful he is willing to offer his often very
useful expertise for our benefit. If you don't like the way
he offers advice, and you feel up to it, just translate it into
what you feel is a more navie-user friendly manner and don't
bother with the editorial comments.

Here are some that I like:
"Special Edition Using Red Hat Linux" by Alan Simpson, pub. Que,
ISBN 0-7897-2258-5. (covers version 6.2 and includes it on CD)
This includes most of the basic stuff you'll need to know, and includes some
more advanced stuff like setting up servers and programming.
"Practical Linux" by M Drew Strieb and Michael Turner,
pub. Que, ISBN 0-7897-2251-8
One of the easiest to understand introductions to Linux.
"Running Linux" by Matt Welsh et al, pub. O'Reilly, ISBN 1-56592-469-X
One of the best introductory books. Goes into a fair amount of technical detail.
"Linux Desk Reference" by Scott Hawkins, pub. Prentice Hall, ISBN 0-13-016391-0
Most of the commands you'll ever use, listed by function. A great reference.
"Practical KDE" by Dennis E Powell, pub. Que, ISBN 0-7897-2216-X
A great introduction to KDE and its apps, including configuration.
"Mastering Gnome" by Bryan Pfaffenberger, pub. Sybex, ISBN 0-7821-2625-1
A great book on Gnome, but doesn't cover the latest 1.2 version.
"Learning the bash Shell" by Cameron Newham and Bill Rosenblatt,
pub. O'Reilly, ISBN 1-56592-347-2
Essential for really getting to grips with the command line.
And for later on, when you get more expert:
"Essential System Administration" by Aeleen Frisch, pub. O'Reilly,
ISBN 1-56592-127-5
Unix, rather than Linux, but will really broaden your knowledge of Linux.
I'm pretty sure that Amazon carry all of these. If you come across some other
good ones, maybe you could let us know about them.

Another possibility might by Lyx. My daughter was using that
word processor that comes with Windows 3.1 (can't remember the name offhand,
the default one, not Word), but we removed the Windows 3.1 partition so now
she uses Lyx which is related to LaTex and can produce LaTex output but
is WSYWIG in nature. The only problem with it is that is uses Xforms
though I've heard they're working on changing that, maybe to Tcl/Tk.

Take a look at MacOS X Bundles:
http://developer.apple.com/techpubs/corefoundation/BundleServices/CFBundleServices/index.html
It use XML the way it should be used (as an architecture-agnostic
manner of storing a small ammount of information) and literally makes
installing applications as easy as dragging them to wherever you want
to put them. I hope these people aren't trying to do something more
complicated than this, as this is the utopia of application
installation (IMHO). You can drag a bundle to wherever you want to
place it (hard disk, network, removable media, ram disk, whatever) and
it will always work; even adding it's shared libraries to the search
path. A bundle can hold binaries and source for a number of
architectures. It also contains meta information about itself in a
standardized manner, which allows automation of program registration
and network updates.
Linux is halfway there already with RPM and deb; but the ultimate goal
is to just get rid of them.

Even if the original poster got his terminology confused. I imagine that
what was being proposed here is using our computers running web browsers
serving and the frontends of applications programs, with the core of the
programs running on the web servers as webpages using CGI's. And possibly
major programs running say as a replacement for an suite of office
productivity programs which communicate with web browser clients as
webservers in their own right.
Can this work? It depends on the programs being replaced, but it can work
for some programs. This does not eliminate the need for application
programs it just relocates it from you computer to that of the web servers.
But being possible does not make it desireable. This does not eliminate all
programs, and never could unless a user limits their need to software to
only what can be handled this way. However there are too many issues and
concerns for this to be desireable.
Years ago when there was no other viable option for most people and they
needed direct computer interaction, they would rent access on a timeshare
system. Using a teletype terminal or a dumb terminal to communicate via a
modem with the timeshare host. The bandwidth of the connection was low by
today's standards (150 baud or 300 baud), but since it was not a shared
resource it was servicable. The bottle neck was the performance of the
timeshare host. Often you might have to wait from several seconds to a few
minutes and seeing the result of it echoed on the screen. These delays were
caused by the timeshare host becomming too busy to keep up.
As soon as any viable options were available, the timeshare system were
abandoned by the users in droves. People in general found the 8-bit, 8K -
48K RAM, 1Mhz - <2Mhz micros much more desireable over the timeshare
systems.
The proposal offered here has all the hallmarks of returning us to the
timeshare era with all of its problems and issues. The text only ASR-33's
and LS-120's text only terminals would be replaced with web client
terminals. The 150 baud and 300 baud non-shared connection would be replace
by TCP/IP shared connections. The timeshare hosts would be replaced by web
servers running the application programs.
That is all window dressing, what that would really amount to is a return to
yester year's computing. Imagine performance when several thousand or
million (or billion?) users are all competing for the same servers. We
should not forget the past and so we should not be condemed to repeat it.

Hello
Probabely this is something pretty easy, but I cannot figure out how to do
it. I am new with Linux and I am trying to install the Oracle 8 server on my
machine. In the installation guide, they say that I have to perform some
tasks as the root user, such as configure LINUX Kernel. Mainly, I have to
"set the kernel parameters" : SHMMAX, SHMMIN and others. How do I do that. I
assume that these parameters should be placed in a file or somewhere in
order to be set everytime the system boots up. Any Ideas?

Because switching from X to a text terminal was causing a color palette
screw up that I could only fix by hitting CTRL-ALT-BKSP in X to restart
X, which meant losing everything I was working on since I couldn't read

ZIP disks are partitioned, so tarring directly to /dev/sdX will utterly
mangle the partition table. This is not usually a good idea, the
space you gain is very minimal, and attempting to mount a ZIP with a
farked partition table can occasionally hang the entire VFS. I know
you're not mounting these disks, but accidents happen. Play it
safe--partition your ZIP and tar directly to /dev/sda1 instead of
/dev/sda.
Don't know why the parport ZIP decided to show up on /dev/sdg instead of
/dev/sda unless you have 6 other SCSI disks in the system, but mangling
the partition table may have confused the drive itself. I couldn't
reproduce the problem on my ATAPI ZIP under IDE-SCSI emulation, so... ?
I haven't had any problems like that with parallel port ZIPs. Anyone
else?
