creating VMDK file for raw disk access by virtualbox on linux host

Posted 05-19-2014 at 03:32 PM by dr_agon

Recently I repartitioned my harddrive and had to recreate VMDK file which is used to access some of my physical partitions by guest machine.
You can do it using the command

Code:

$ sudo vboxmanage internalcommands createrawvmdk -filename test.vmdk -rawdisk /dev/sda -partitions 1,3

The result did not satisfy me, because guest machine required RW access to entire /dev/sda.
Looking for description of VMDK format I have found this.
So, I modified the lines in VMDK file...

Recently I got sick of new KMail. I tried to be patient and after upgrading to new KDE4 (together with Kubuntu 12.04, which is "Long Term Support", so it was ment to be "stable") I ran trough all pains with migrating my e-mails and configuring it together with Akonadi, Nepomuk, and Virtuoso. I hoped to get the whole KDE-PIM usable again. Now, after half a year, I gave up and searched for replacement.
I needed Mail User...

Where are desktop icons stored in KDE4 Plasma?

Posted 03-06-2011 at 06:34 AM by dr_agon

Tags desktop, kde4, plasma

After switching to KDE4 I was little confused with its new philosophy of Plasma containers and activities. As it looked interesting, I tried to find more information. Now, there are some nice posts showing how to use it, but I couldn't find the answer for a simple question: where the information about desktop icons is stored on a disk?

Just for the record, in KDE 4.4.5 it is in
'~/.kde/share/config/plasma-desktop-appletsrc'

batch resize images using find, xargs and convert

applies to: linux, find, xargs, convert, image processing

'convert' command, which is a part of ImageMagick package can be used for image resizing, but it lacks ability to process multiple files (in version of ImageMagick 6.5.7-8 2010-12-02). Instead of writing a shell script you can use find and xargs commands to collect filenames and invoke convert with one filename at a time, like this:

Code:

find -iname "*.jpg" -printf "%f\0" \
 | xargs -0 -I {} convert

Differencies between OpenOffice.org under Windows and Linux

Posted 12-02-2008 at 03:53 PM by dr_agon

applies to OpenOffice.org, Linux, Windows, Python, XML

Recently I try to develop modules for already existing, big project using Python and OpenOffice.org. The application is meant to work both under Linux and Windows. Unfortunately, it is not easy.

Python-UNO bridge to OpenOffice, which is part of OO suite, is different. Under Linux it works flawlessly with the fairly new Python v. 2.5. Under Windows it works only with supplied Python v. 2.3.4. It wouldn't be so bad if recent wxWidgets
