As it comes from the title below is a small set of Christmas holidays wallpapers which should fit any Ubuntu, Fedora, Debian, Suse, Mandriva, Slackware, RedHat, Centos desktop…

Well, as for now it is not a problem anymore to open Microsoft Office 2007 .docx documents in any Linux distribution coming with OpenOffice suit. It may be Ubuntu (Feisty, Gutsy, Interpid whatever), almost any version of Fedora/RedHat/Centos, *SUSE, Mandriva and of course Debian (as per my personal opinion it’s the best one).
What is .docx actually? It’s Microsoft’s file format representing word processor documents and named OpenXML (as an attempt to create open and free international standard). Today .docx is default format for Microsoft’s word processor Word.
There are myriads of online converters between OpenXML and OpenOffice formats including .docx, .xlsx, .odt and many etc but sometimes it’s much more better to just open received .docx file in Linux offline (if there is temporarily no Internet connection or for security/private reasons etc).
So, just download the following package to certain directory like /usr/src, here are the commands to do it:
1. cd /usr/src
2. sudo wget http://blog.mypapit.net/imej/odf_filter.tar.bz2
The next step is to unpack the contents of the archive (.tar.bz2 is definitely well compressed file) and copy 3 files to OpenOffice’s system directories:
3. sudo tar -xvjf odf_filter.tar.bz2
4. sudo cp OdfConverter /usr/lib/openoffice/program/
5. sudo cp MOOXTypeDetection.xcu /usr/lib/openoffice/share/registry/modules/org/openoffice/TypeDetection/Types/
6. sudo cp MOOXFilter_cpp.xcu /usr/lib/openoffice/share/registry/modules/org/openoffice/TypeDetection/Filter/
As you can see from picture below now it’s possible to natively open .docx files in openoffice under Linux. Of course such “native” support may imply some artefacts in opened files due to file formats incompatibility so it’s also a good option to ask your friends to convert .docs into .pdf before sending you 
P.S. Thanks to guys from mypapit.
P.S. Here are several online converters .doc(x) <-> .odf <-> .pdf:
1. ZAMZAR (possibly the best converter), 2. http://docx-converter.com/.
In order to convert WMA file into MP3 format in Ubuntu (or Debian) you should install the following requirements first:
1. mplayer (sudo aptitude install mplayer)
2. lame (sudo aptitude install lame)
3. win32 codecs (sudo aptitude install ubuntu-restricted-extras)
and then convert file.wma into file.mp3 using the following console command:
mplayer -vo null -vc dummy -af resample=44100 -ao pcm:waveheader file.wma;lame -m s -V 3 audiodump.wav;mv audiodump.wav.mp3 file.mp3;rm audiodump.wav
This also works for Fedora / Centos / Redhat family Linux distributions (requirements should be installed by yum package manager via third-party software repositories).
There is still no native Linux support of newly unveiled browser Google Chrome but guys from CodeWeavers prepared the port of Chromium (official name of Google Chome for Linux). This staff is already available for downloading as DEB packages for Ubuntu (32-bit and 64-bit), as RPM for RedHat, Fedora, CentOS etc. as well as self installable script for any other Linux distribution.
Well, after quick testings there are no doubts that it is not a good option if you wish to have quick and stable alternative for Firefox… But of course it is good for evaluation purposes or for those people who CAN’T wait for official release of Chrome for Linux Certainly the port is based on Windows copy run by Wine (don’t forget to upgrade it). Actually CodeWeavers says that this is just a proof of concept, for fun, and to showcase what Wine can do.
Checkinstall is extremely useful utility to create .deb packages for Debian, Ubuntu (or .rpm packages for Fedora, RedHat, CentOs) from .tar.gz (or .tgz) source tarball after it’s compiled at your Linux box. In other words you can prepare binary package for later usage without need to compile software from sources every time you need to get it installed on certain Linux box.
Another application of checkinstall is software deinstallation that was compiled and installed from sources. As you might already noticed, not every programmer adds “uninstall” rule to Makefile and thus command “make uninstall” would fail. The nice solution is to use checkinstall to prepare binary package from sources and then install or uninstall it with dpkg command (or rpm in RedHat based distributions).
Here is the short algorithm on how to prepare .deb package from clamav source tarball:
1. Install checkinstall:
sudo aptitude -y install checkinstall (Ubuntu, Debian and related distributions)
or
sudo yum install -y checkinstall
(for rpm based distributions, please note that checkinstall usually isn’t included to standard Fedora/RedHat repositories, so you will need to link up third party repo like DAG)
or
compile checkinstall from sources
2. Get clamav sources:
wget http://mesh.dl.sourceforge.net/sourceforge/clamav/clamav-0.81.tar.gz (as an example)
3. Install libraries that might be necessary for clamav compilation:
sudo aptitude install libgmp3 libgmp3-dev
(this command is applicable for Debian and certainly will be different for Fedora or RedHat)
4. Compile clamav:
tar xvfz clamav-0.81.tar.gz
cd clamav-0.81/
./configure --sysconfdir=/etc
make
5. Run checkinstall and follow its intuitive instructions (enter package description etc.):
sudo checkinstall -D make install
6. When finished you’ll get clamav-0.81_0.81-1_i386.deb (or rpm package if you use Fedora/RedHat/CentOs) you may want to install with sudo dpkg -i clamav-0.81_0.81-1_i386.deb (or sudo rpm -i ...) or move to another PC for later installation.
