how does one configure an ubuntu for no swap ? disabling the swap partition will do ?

I'm not sure you can have no swap easily, however you can definately tune the kernel to discourage swapping.

You could try setting /proc/sys/vm/swappiness to zero. You can just echo into it on a running system or you can set vm.swappiness in sysctl.conf

I disabled all swap files but winXP still accesses my HDD every few seconds

Could be anything, first things to check are microsoft components though, indexing and windows update are usual suspects.

for a one off

sudo swapoff -a

or more permanatly

just comment out the swap partition in the /etc/fstab file

Think carefully about what level of overcommit / how you want the oom killer to behave if using these methods.

Never choose to use a journaling file system on the SSD partitions

Wait wouldn't this mean most modern filesystems? Surely not.

That's just bollocks. With journaling off you have no way to verify the integrity of your disk if you have a crash whilst writing data. Unless you don't care about your data leave journaling on.

You can mimimize the journaling, i.e. data=writeback on ext3 but it's still not a good idea unless you have another trusted journal of your data elsewhere (i.e. a some sort of binary/write ahead log in your app).
