Using mutt I organise my mails as threads in the index view.
This way I often have the problem that I miss a reply to a very old thread because I always jump to the end of my mails to see the new ones instead of cycling through them with tab.
I just stumbled over a way to solve that. There is sort_aux. This variable controls how threads are sorted in
relation to other threads and how branches in a threads are organised. The default is date and this value accepts anything sort accepts except for the value thread (obviously).

Fortunately there is set sort_aux=last-date-received which does exactly solve my problem. By specifying this a thread that receives a new message is automatically
moved to the end of the index and becomes the last one displayed. No way to overlook mails this way.

Maybe some people suffer of the same problem..

It seems to be possible to highlight URLs in urxvt and to open them in a browser with a mouse event similar to the terminal emulators the big desktop environments use.
This is possible via various perl extensions (see man 3 urxvtperl). I use the following in ~/.Xdefaults and make use of the settings on X start via xrdb -merge ~/.Xdefaults but you can also use them by executing urxvt with the -pi option.

URxvt.perl-ext-common: default,matcher enables the string matcher extension and default turns on a set of default configuration values.
The mouse button to open the URL can be specified via URxvt.matcher.button: (by default it's the middle mouse button). You can also specify your own sets of regular expressions to match any string in the terminal and specify different launcher events for each of them. I didn't see this before as I switched from aterm to rxvt-unicode because aterm is not maintained upstream anymore, has quite a few bugs, urxvt has unicode support and the command line options of aterm are a subset of urxvt's

Yeah I now did an aptitude install molly-guard (I guess most sysadmins know this tool, thanks mika for the hint) after I
halt'ed modprobe.de by accident (Strato dedicated server). I was also able to reboot my file server at home 2 times last week because of.... ssh, well and of course bad shell prompts, inattention etc.

The tool is basically a replacement for halt, reboot and shutdown to prevent such accidents. To give you an impression what this looks like:

[root@bone] /home/nion/ halt
W: molly-guard: SSH session detected!
Please type in hostname of the machine to halt:

UPDATE from madducks comment:
Please note that etch's molly-guard has a bug that hits people running shutdown -h: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=426107.

I suggest to install version 0.3-1 from testing, which shall be in etch r2 soon.

The LSB functions in Debian can do fancy and non-fancy output. However, the output is not really fance compared to grml, gentoo and Ubuntu. They have these nice, colored ok or fail messages in brackets
If you are like me and you always want to have the coolest bling bling Try this patch:


Of course this only works for init scripts including and using the lsb functions (should be most of them).

Quite a few people have the problem that they use automatic file system checks and may have a check at a bad point in time.
For example if they boot their notebook before a presentation or the battery is low.

e2fsck the tool which does the file system check has a config file (it doesn't exist by default) with an option to workaround this.
Just insert:

[options]
allow_cancellation = 1

to /etc/e2fsck.conf and you will be able to press Ctrl-C during the file system check to cancel it.
