:1) can i resize my partitoions without reinstalling slackware (with cfdisk,
:for example)?

Not really. fdisk/cfdisk destroy filesystem information on partitions
while they change partition dimesions. However, there is a Windows
utility, called "Partition Magic", that does know how to resize partitions
_and_ preserve iformation on it. However, best way to do such an operation
is, IMO, backup -> reinstall -> restore.

:2) how would you recommend me to partiton my hard disk? (how much mags for
:/var for example)
:
:i got 600 mb's (that i all gave to / - that wasmy mistake)i plan to use
:my computer as a desktop running KDE or gnome, runnig allot of X11 software,
:and programming too, i dont have any users on my box and i dont think im
:gonna have any web server nor e-mail server running, so, that's my needs. if
:you could tell me what you think i need i'l appreciate it allot!

First, refer to "Large Disk" mini-HOWTO, "Hard Disk Upgrade" mini-HOWTO
and to "Linux Filesystem standard". My opinnions remain my opinions, take
it as is, without any warranty on my words. Also, I may be wrong. Rule of
thumb say to listen to everyone, but to make own decision.

My partitioning is:

vroom:~# df
Filesystem         1024-blocks  Used Available Capacity Mounted on
/dev/hdb1             194405  105517    78849     57%   /
/dev/hdb5             598634  437606   130105     77%   /home
/dev/hdb6            1997036 1322155   571665     70%   /usr
/dev/hdb7            1080454  410111   614519     40%   /usr/local
/dev/hdb4            2020364 1871701    44241     98%   /usr/local2
/dev/hda2            1910912 1611776   299136     84%   /win

but it seems that it will not fit into your needs. According to those, I
think that following scheme will be ok:

/ - a small  (<30 MB) _primary_ partition

/win partition, _primary_, of course

/home partition, primary. You"ll want to keep it primary just to be a bit
safer. It size should be around 250 MBs.

An extended partition, wich will hold:
	swap - put it at the very end of disk.
	/usr - 250 MB will do, if you are not willing to install junk.
	/var - 30 Mb.

/usr/local should be linked to /home/usr.local Reason is: When you will do
your harddisk upgrade, there will be _one_ place to preserve (hm, there
will be /etc files, /usr/etc files, /usr/X11R6/lib/X11/XF86Config file ..
in any case. Just one partition to care, that is)

Beforementioned junk includes: 
	KDE in addition to GNOME or vice versa
	25 different mail readers - you will need just one.
	Netscape Communicator (IMHO)
	Xemacs (IMHO)
It can be tricky to install all you need into 250 MB, decisions can be
hard. (Once I used to run a Debian system on 140 MB, now I ru Debian on
6.5 Gb. I use just the same things: plainn wm, no GNOME, no KDE, Apache
web server, Netscape Navigator (well, now it is Mozilla M13), scheme
environment and Emacs. This is to illustrate the Software Murphy Law: when
you have more disk space, you will save more junk. In any case
productivity percentage will go zero).
