GNU/Linux needs 128 minimum, in fact one of the advantages of GNU/Linux is
being able to run os small rams (had debian running on a 486 with 8 MB).
however you'll need to be a bit careful about what you use and what you
have running when you have small RAM. here are some tips.
- don't use X if you can
X windows and the desktop are the ram hungry parts of the OS the rest (the
GNU tools) have been designed ages ago when RAM was very expensive. so
using the command line will generaly make your machines performance more
efficient (and will make you more efficient too).
- if you have to use X use frontends
many GUI programs are just frontends for console or command line tools,
these usualy use less ram than hardcoded GUI apps.(for example use Lyx for
your wordprocessing instead of Koffice or Staroffice or gqmpeg instead of
- try to find a smaller alternative to your favorite software
for instance all Mozilla based browsers (netscape, mozzila, galeon) use too
much ram (and disk space too) while opera is too small to be true and it
does almost all things gecko can do (arabic is not there yet though). the
only problem with opera is that its not free, but its zero price so its as
good as netscape.
- boot the the console
when your system automaticaly boots to KDE or Gnome it usualy runs an X
login manager like XDM, GDM or KDM this manager stays in the RAM even
after you login or out. when you boot to the console (or shell) you just
run startx and X will open 3alatool.
- use a light desktop
KDE is very resource hungry, Gnome is better but still, if you use a light
desktop or a small window manager it would be much better. there are many
light desktops out there among them are Xfce
or you could just use plain Gnome window managers without gnome try
although I have enough ram I always have a light desktoip installed just
in case, I may need to open to many programs at the same time or I may
loose a ram chip or anything. so mainly I use blackbox I think its very
good. but beware these small and simple desktops and window managers are
not trying to imitate M$ windows at all, so it may take some time to get
used to them.
- reduce color depth
you'll hardly ever spot the difference between 16 bit and 24 or 32 bit
graphics, keep it at 16 bit max (if you don't care about graphics that much
you may consider making it 8 bit even).
- reduce resolution
this is usualy not a welcome step and its not really need it if you have
64MB but it helps if you are desperate.
- don't use virtual desktops or at least use less desktops.
virtual desktops are these numbered boxes in your panel, it take lots of
RAM to keep them all up.
- don't use a background image
if you have to then use a small pattern screen size images can take up to
8MB of your RAM
- don't use screensavers
yes the screen saver is loaded in the memory all the time, try to set up
power management instead.
- clean up your services
services are these programs loaded at boot time (when you see a message
that either ends with OK or FAILED) many services are not that important
(for instance loading the MySQL deamon while not using databases, or the
sendmail deamon when you only use webmail also on some distros wine loads
some service, and for most people wine doesn't work or isn't really useful,
you may disable it). your systme should come with a wizrd or GUI tool to
help you in configuring services if\ not then switch to Mandrake now :-)
(I'm a real junkie ain't I) on a more serious note nearly all GNU/Linux
systems come with linuxconf
linuxconf is a very useful distro independent administration tool.
run linuxconf and go to control panel--->control services
the rest shoudl be easy to guess.
but linuxconf will not document your services so it may be hard to know if
you should disable them or not.
- configure the swap right
the swap partition should be at least your RAM size and there is no real
reason to make it larger than double your RAM. 200MB is also a very good
maximum (even if you've got 512MB RAM :-)
I can't think of other useful tips, but this is a very big topic and I'm
sure most of you will have good ideas I never thought of.

existed last year is not likley to be with us till now (except for internal
modems and arabic support, the later is because of lack of arabic minds
working at it off course). this is a fact that makes you think about how
useful conventional paper books could be with such topics.

don't know about that, seems lots of linux users would prefer to write HTML
code directly or use more advanced tools like writing stuff in SGML or TEX
first and then exporting it to HTML. I think it realy depends on what kind
of HTML code you'd like to produce, if its simple document like articles
but you'd still like to use frams and tables then a wordprocessor that can
export to HTML would be enough (staroffice makes very good HTMLs and they
are even human readable when you look at the code).
maybe someone else can help us more here.

is or how it works, but what you need is a duplicate.

be much easier since it uses the more advanced urpmi)

make it 2X your ram but no more than 256 mb (alaa's recomendations "for
me my swap is 200 mb / 92 mb ram")
i was running gnome with 30 mb ram once
it was slow but usable
also kde 1
but didn't try the new versions

just try your hands with any text editor :)
