kubuntu intrepid automount external harddrive

The new intrepid kubuntu comes with a nice plasmoid where mountable partitions show up wehen you plug in USB flash disks and external hard drives.
The problem is, they don't get mounted automatically, which is what I want (to streamline my backup process). Fortunitely I found this thread which gave me a hint:

I first tried to download and build devicenotifier_automount from sources, but then after downloading a ton of -dev packages etc. and still not getting it to build, it dawned on me to look for a PPA. I found one:
I've installed it successfully but haven't restarted X & tested yet.
Edit: so it seems you don't need to restart X, just use the `New Device Notifier Automount` plasmoid. Works great so far (2 minutes of testing:)

bash echo on

I've searched previously for a way to echo all the commands in a bash script.
Today i found it on a asp page of all places:

set -o verbose #echo on
set +o verbose #echo off

If you want to do it once to debug a script you can also do:
bash -x

some words of the day

I regularly send out a word of the day/week/month, so I decided to also publish them on my blog from now on. So without some further ado, here is the some of all:

and of course my favourite: somesuch!

There you have it: all the words starting with some except the ones starting with somer. Like me, I know you always wanted to know that.
This list was compiled using the linux command `look some`.
This post was inspired by my friend Sizwe Mabanga's saying: "Someway Somehow".

Have you ever downloaded a .deb file and wondered what the best way to install it is?
This little gem of an app, does the trick for me. It installs the file while resolving and installing all its dependencies!

gdebi is a simple tool to install deb files. It lets you install local deb packages resolving and installing its dependencies.

apt does the same, but only for remote (http, ftp)
located packages.

It has a graphical user interface but can be used in your terminal.

I recently went over to Kubuntu 8.10 (Intrepid), and I'm trying to get used to dolphin now. But it doesnt have the super cool "file size view" which I used to love in konqueror.
The soloution is to install kdirstat, which pretty much has the same functionality.
(Found it on Too many open files

We hit this again on sles today, so I thought I should leave a note here for posterity. /home/tcmas/tomcat/5.0.28/work/Catalina/localhost/balancer/SESSIONS.ser (Too many open files)

  1. It might be caused by the small amount of memory available! so increasing that, may fix it.
  2. It may also be the the number of open files limit on linux:
Increase file descriptor limit under Linux to prevent Too many open files

Get current limit:

ulimit -n

cat /proc/sys/fs/file-nr

The default limit is 1024.

Get current number of open file descriptors:

lsof [-p pid] | wc -l

Increase the limit:

Edit /etc/security/limits.conf:

Monday, 10 November 2008 114: [[: not found (Oracle XE problem on ubuntu)

I installed Oracle Express edition on Kubuntu again, and I got a familiar error again after running:
. /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/
/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/ 114: [[: not found

the solution is to change (as root or sudo) the first line in the "" from
#! /bin/sh
#! /bin/bash

Figured out how to save my kde4 session

just run:

dbus-send --dest=org.kde.ksmserver /KSMServer org.kde.KSMServerInterface.saveCurrentSession

For some reason my HP laptop crashes from time to time, and then my session disappears :'(

I found this gem of an app a while ago, for monitoring the current network usage.
After installing intrepid, I had to look for it again, so here's the link
