Suse comes with a lot (6 CDs) of stuff at a very low price
(about $30 US,street price). It is my favorite distribrution. It is
more of an "engineer's distribution" that lets you have a lot of set
up control but is also pretty automatic.
Caldera is probably the easiest to install--you can even
install it from Windows by clicking on an icon.
Red Hat is in between the two.
Turbo Linux specializes in a lot of asian languages (and may
have better character set support, from rumors I hear).
Any of the distributions will get you started, though.

Hi, I have the same card and couldn't make it work with sound until I
got the
2.2.11 kernel (now I have the 2.2.12 and it works great)
Just download the kernel and look at
/usr/src/Documentation/video4linux/bttv/README.WINVIEW
It is now supported.
BTW, I am ***NEVER*** going to buy anything else from Leadtek. They
don't give a damn about customers, don't reply to e-mails (unless, of

I guess it has something to do with the bttv Makefile. I think there was
a file named "update" in bttv/driver, try ./update in this dir

Well, your comment _appears_ correct for the current strategy of
Amiga, putting the OE on top of Linux. But I think the original QNX
idea was to take QNX (all of it including photon) and to improve a
number of its features (specifically the multimedia and Java aspects).
Certainly all the screen shots and hype at the time seemed to point in
the direction of using the core QNX componenets (i.e. kernal
filesystems Dev Net etc etc - plus photon with extras). I think this
is basically continuing now with Phase 5. Some of the new
announcements on the QSSL web site are very promising in this respect
- both the Citrix and the Java Enterprise stuff could have a major
impact on a home QNX system. Imagine a home server running QNX (or
derivative) with satellite screens (using photon ditto), that could
still host Windows apps using Citrix and support full Java.

Of course... ;-)

I don't, I think Amiga is now dead, (except as a Linux PC with custom
desktop and some nifty Java apps). I have high hopes for Amirage.

They probably will offer Linux / Windows dual boot, with amiga
compatible FS for Linux and classic amiga emulation. Plus some of the
Java Amiga objects. It will sell to Linux / Amigans but it won't
really be an Amiga. I think Gateway need the Amiga name to avoid
upsetting MS too much.

QNX does a number of things right that Linux does flat wrong (true

I'm sure you're right, the problem for QNX is that few people know how
good it is because it is so expensive (aimed at a different market).

Hmm, cant point you directly to any books or sites, but I can give you
some hints if you like:
Firstly partitioning decisions are not that imperative. Breaking
filesystems down into partitions can help robustness a great deal, and
linux's method of achieving this is by mounting seperate partitions on
the root filesystem as commonly used directories. This does entirely
depend on what you are intending to use the system for. It is always
possible to make lots of smaller partitions then link in common
directories using symbolic links to keep them safely on a seperate
partition. The same can be achieved to divide up user file space.
Generally, for simplicity, I would go for about a quarter of the space
to the root (/), between a third and a half to /home (if you intend to
have quite a lot of users, maybe even more than that, again, it depends
on disk size, I wouldnt use more than 3 gig for the root filesystem, any
excess is probably better devoted to the home directories). For some
reason all of the information I have seen suggests having a couple of
hundred meg for /var (about 200-300?), though mine only currently has
23Mb used, and I have a lot of software on my system. It is also a good
idea to have some space devoted to a /tmp directory, as commonly
accessed and manipulated files are more prone to error (however small
the chance, its bigger if you play with it ;-). Last of all, it might
be an idea to use a realtively large space for an /arc directory (lots
of linux/unix users around the world just said, "huh?"). I use it to
store archives of software installed on the system, rpms, tar files,
gzipped files. Because its a seperate partition is means you have a
good chance of recovering all of your software should another part of
the disk fail. It can be useful to archive some other components of
your system and keep them here too (anything you dont want to lose...
can help to have a seperate partition to back up onto, a second hard
disk is better for this purpose though, if you have one).
As for adding user accounts, as we say in Glasgow, piece of pish. Login
as root and use the adduser command to add a person, eg:
adduser Bob
Then give them a default password with passwd, eg:
passwd Bob
You will be prompted to enter a password twice, make it something
simple, give it to the user, then they can log in. Once logged in the
user can use passwd again, without a parameter to change their password
to whatever they want.
Da da.. easy huh? Most linux distributions actually have some kind of
control panel with a nice graphical front end for user adding etc, so
you may not even need half of this, good luck,
James

It also hides a diagnostic if you forgot to include <stdlib.h>. This I
consider to be a major disadvantage.
I never make this mistake in my own code: my fingers automatically type
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
at the top of source files before thinking about what I actually need;
however, omitting the cast has quite often saved me some embarassment
when editing other people's code.

I suspect that Mr Seebach is referring to those unfortunates who try to
program in `C/C++'. These induhviduals are, I suspect, unworthy of
considerarion in a discussion about good style.

When trying to run the fetchmail command I get the error message\
fetchmail: no mailservers have been specified.
I ran the mc file tcpproto.mc to create a cf file for sendmail.cf
and I only added DOMAIN(generic) to the actual file before compiling. I
am running a small internal tcp network with a linux box and serveral
windows 95 workstations. =20
At one point I could actually get mail using Eudora lite to check for
mail. Mail on the server itself has gotten worse. =20
I configured several files: db.mydomain.hosts, db.###.###.###.hosts,
named.ca and resolv.conf and this gave me dns (verified with nslookup),
but the mail just gets worse. Any ideas?
How and where do I specify a mailserver?
Thanks - Pam

Using NS v4.61 here I've noticed that if Netscape can't
contact a news server when you start it up it won't display
it in the list. But if you start it up another time when it
can contact the server it will. Eg, I run a local server on
my home lan which shows up every time I start Netscape. But
my ISP's news server only shows up when I am connected to
the ISP.

The arguments to `main' are, in most implementations, passed regardless
of whether they're declared or used. This will make no difference to
the program's performance: a sensible compiler will notice that the
arguments aren't used and use the registers for something else.
As to the use of `printf', well, it's traditional. ;-)
The program is, at least, correct and portable. This is a major
advantage over an awful lot of rubbish I've seen produced by `C/C++'
programmers.
If you want a bloated memory hog which prints the classic greeting shown
above, I can direct you towards GNU Hello.

HI !
that´s quiet easy ... after partitioning your hdb mount it at ... lets
say
/mnt/mnt1 and do "cd /mnt/mnt1 ; tar cvp -exclude=/mnt/mnt1 / | tar xfp
-"
after this you have to remove the contents of /mnt/mnt1/proc/* and
edit your /mnt/mnt1/etc/fstab to get your mountpoints and swappartys
right ... do not forget to edit /mnt/mnt1/etc/lilo.conf
then "cat /boot/vmlinuz-{whatever your LILO loads} >/dev/fd0 &&
rdev /dev/fd0 /hdb1 && sync"
this creates a bootable floppy which looks for its root-device on hdb1.
boot from this floppy and run lilo ...
If your BIOS has no problems booting from hdb1, then you´re all set
... i guess :)
