Read that as, you can watch videos, show gif, jpegs and such and have other animated thingys. I would also add, I bet it is going to be more secure too. From what I have read on this list and the notices I get from the US Government alerts, Adobe Flash is about the most insecure thing there is. The only thing that may beat it is windoze 95. ROFL I read about Youtube and it's testing. I have not tried it on a permanent basis but I did do a one session test a while back. I couldn't SEE any difference. I think that is a good thing myself.

Not sure about Active Directory, but I have used Samba's winbind to authenticate Windows domain users on a Linux box.

I exchanged 'mplayer %U' by 'xterm -T MPLAYER -e mplayer %U' in the settings, now mplayer runs in a terminal, and all is fine. I created a window rule so the terminal automatically minimizes. Cool! It only happens in mplayer and mplayer2. Other players work fine, but I like mplayer best, and prefer to run it without any window decoration. Now, would this be an MPlayer problem, or one of Dolphin?

Contrary to my previous email, sent in error, that does NOT work. Did you check this yourself? $ LESSOPEN= less file.html# works fine $ LESSIGNORE='*.htm*' less file.html#does not I've also tried `export LESSIGNORE='*.htm*'` (for what difference that makes?) and tried running the `less` command on a separate line. What version of less are you using, please? I have =sys-apps/less-444 installed here. As per my previous reply to Canek's suggestion, I now have a working solution. LESSOPEN is the keyword that works for me, here. So I only make this reply to you now for completeness, as part of the eternal quest for deeper understanding and for the benefit of those searching in the future. LESSIGNORE seems even more poorly documented than LESSOPEN - I'm afraid I never think to use `info`, only `man` in the first instance. Stroller.

Is there a way to find out what is using swap? Maybe something related

I have always wondered how to find this out myself.
Me too, so when I had this sudden swap problem for the first time, I
searched for a method to do this and found a script here:
http://northernmost.org/blog/find-out-what-is-using-your-swap/
There's lots of information for all processes in /proc/pid/. Trying to
read /proc/pid/mem (I think it was this file) in mc was not such a good
idea, the system froze with lots of HD activity, and after half an hour I
rebooted with Alt-SysRq-{K,E,I,S,U,B}.
I improved the script a little, it allows sorting by PID, size and name,
and can restrict the output to specific processes or show only those
using more swap than specified. If interested you can download it here:
http://www.wonkology.org/utils/getswap
You need to be root to see processes you do not own.
But of course, I forgot to run it after the sudden swap problem happened
lately. So I still do not know what was going on there. I'll wait for the
next time it happens.

[gentoo-user] fsck separate /usr
Hi there! I'm using the new udev with a separate /usr partition. It was encrypted, and it seems there is no solution yet for this, so I moved it over to an unencrypted volume - no problem, /usr is one partition where encryption does not make that much sense anyway. Works, but after an unclean shutdown (reading files in /proc/pid/ was not a good idea) /usr wants to be fsck'ed. But it is already mounted at that stage. The boot process just continues, but I wonder what one should do to make the fsck run. Except for using a live cd. Maybe I should just enlarge my root partition and move /usr there, at least this would avoid all the trouble. But I'm used to many separate partitions, and like it that way. Wonko
