Namebench: cross-platform DNS benchmarking tool

Date: January 15, 2011. Categories: applications, debian, links, linux and ubuntu. 0 Comments

It was long time ago when I wrote here last time but today I’d like to share the link to an application that would be appreciated by everyone starting from Linux starter wishing to speed up his/her Internet connection and ending with system administrators who may want to run benchmarks and run stress tests against certain DNS service(s). I am talking about Namebench. This is cross platform tool written in Python that makes it possible to easily select the fastest DNS available in your area as well as to run benchmark tests directed to DNS entries.

All what you need to have to start using namebench is Python and Tk library, e.g. if you use Ubuntu or Debian just run the following command to meet namebench library requirements:

sudo apt-get install python python-tk -y

When done go to namebench’s official website and download the latest tarball from there. For example 1.3.1 is the latest version for today so you can download it directly from here. Or you can just take below steps:

cd /usr/src
sudo -s
wget http://code.google.com/p/namebench/downloads/detail?name=namebench-1.3.1-source.tgz
tar -xvzf namebench-1.3.1-source.tgz
cd namebench-1.3.1
./namebench.py

Here you go:

The application has the only button so I believe it won’t bring any problems even to Linux newbies :)

Listen to the cheerful grinding of your harddisk as you reboot into an all-new kernel – and I’m sure that if your computer could smile, it would have a big silly grin on its non-existent face. So as you sit there in your basement, give your computer the holiday cheer too.

2. Top 10 Coolest Open Source Applications in 2008. Well, good reading in New Year Eve.

3. Bootable FSF membership cards: USB flash drive comes with pre-installed gNewSense 2.1.

Open .docx documents in Linux (OpenOffice)

Date: December 15, 2008. Categories: applications, centos, debian, distros, docs, fedora, howtos, links, suse, tips and ubuntu. 5 Comments

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/.

    Caldera has made two announcements today: They will be shipping Sybase with their next release of OpenLinux, and OpenLinux 1.3 will be out on September 28th 1998.
