Starting programs automatically at startup in Gnome
2008-01-01 22:51:00
There are some applications we always start as soon as we log into our Linux, as Firefox or our news reader. If you want you can ask Linux to start these programs for you as soon as you log in, to do this just go to: System->Preferences->Sessions in you Gnome menu. Now click on Add, and fill in the fields the appropriate info, so you can start you new application. Put in name the name of the application, in command the command you need to start that applications (better if you use the complete path) you can use the command which to know where an application is. in this case I used which firefox Then fill in comment anything that will describe to you, what that command is going to do. You can start as many applications as you want, but of course this will slow down your Linux boot up.

Installing Microsoft True Type fonts on Linux
2007-12-31 06:43:00
We the Linux users, are always interacting with Windows users, and one of the most difficult part of that interaction is the exchange of documents, that they create and edit mostly with Microsoft Office, and we use Open Office, and I think that even if they use OpenOffice, they will have access to the system's fonts, so, we need MS fonts installed in our Linux Operating System, in order to look at the documents in the same way they are looking at it. Let's go first with Debian / Ubuntu It is really easy, just enter at the console, the command: sudo aptitude install msttcorefonts And that is all. Fedora / Centos Here we will need a little more job 1. Install the software needed sudo yum install rpm-build cabextract 2. Download the specs to build the RPM wget http://corefonts.sourceforge.net/msttcore fonts-2.0-1.spec 3. Build the RPM rpmbuild -ba msttcorefonts-2.0-1.spec 4. Install the RPM rpm -ivh /usr/src/redhat/RPMS/noarch/msttcorefonts -2.0-1.noarch.rpm Thats all, now you have ...

Rename multiple files with Linux

Different ways to rename bulk files in Linux , using mv and rename We are going to explore different ways to change names of multiple files using command line of Linux Operating System. We are going to use rename which is a perl script, and also the know mv, together with for, in "one-line" shell script rename Syntax rename [ -v ] [ -n ] [ -f ] perlexpr [ files ] -v Verbose: print names of files successfully renamed. -n No Action: show what files would have been renamed. -f Force: overwrite existing files. perlexpr Perl Expression Regular Expressions ^ matches the beginning of the line $ matches the end of the line . Matches any single character (character)* match arbitrarily many occurences of (character) (character)? Match 0 or 1 instance of (character) [abcdef] Match any character enclosed in [] (in this instance, a b c d e or f) ranges of characters such as [a-z] are permitted.

Linux command: What is my IP? (Public IP address)
2007-12-30 01:44:00
Lots of times you need to determine your public IP address, if you are using Linux operating system to power your PC, you may use some good console commands to guess your public IP address. Using wget wget -q -O - checkip.dyndns.org|sed -e 's/.*Current IP Address : //' -e 's/ Using curl curl -s checkip.dyndns.org|sed -e 's/.*Current IP Address: //' -e 's/ curl -s http://whatismyip.org/ Using Lynx lynx -dump checkip.dyndns.org lynx -dump www.whatismyip.com | grep 'Your IP' As you can see, there are a lot of ways to check your Public IP address using console commands in Linux. Of course you can always open a browser and enter any of those URIs and check there.

Debian GNU/Linux 3.1 (Old-stable) updated
2007-12-29 02:14:00
This is really good about Debian , its 3.1 version (old Stable) is still getting updates, and maintained, which are great news for all those servers which are still using the old Sarge. You can get the new updated CDs from here Those who frequently install updates from security.debian.org won't have to update many packages and most updates from security.debian.org are included in this update. So if you usually run apt-get upgrade you should not worry about anything. Read the announcement here

Four days ago, Drupal has released the RC1 for its 6.0 version, we are really near to start using this new version.

Before upgrading, check that all the modules you are using are available or ported to 6.0 version, you can do that, by going to modules page and select 6.0. Check the post at Drupal site here

Using Tasksel on Ubuntu

Ubuntu as a Debian derivative has in Task sel a great tool, from where you can easily install some applications Tasksel, is a tool that comes from Debian, and it was not first included in Ubuntu by default, but since Feisty I think it is included by default, if it is not installed in your Ubuntu version you can install it running: sudo apt-get install tasksel It looks different in Dapper than in Feisty or Gutsy, here is how it looks like in Dapper Drake. For the Debian users this is familiar, as you will see this same image when you are installing Debian, Ubuntu Users does not see usually this image, but as you can see is really useful is an easy way to install servers like DNS, Mail, File or Web Servers. If you want to know which packages includes each group run: sudo tasksel --list-tasks It will list all the packages included in a group. Some Fedora or CentOS users may see it as an equivalent of yum groupinstall Well with Feisty or Gutsy it is even more useful as it has better opt...

Writting your resume with LaTeX

I have written some LaTeX documents, LaTeX is great to help you give format to documents, as for your CV or Resume , it is a real good idea to use LaTeX instead of Word layouts, as the most of people use them, so if you want to have a resume different to the rest, use a different editor, give it a different format, make it look more "professional" so you can have better opportunities that the people reviewing the CVs take yours just giving a glance to the CVs. Here is my collection of documents of LaTeX. Today I have found this good tutorial to write your resume with LaTeX check it here.

Cisco does not fully support Linux
2007-12-21 13:00:00
The Cisco Catalyst Express 500 software does not support Linux Yesterday I had to configure my Cisco Catalyst Express 500, of course I do not have any copy of Windows on my PC, so I started reading the instructions. Getting Started guide for the Catalyst 500 where it clearly says. Equipment that you supply to set up the switch: 1. A PC with Windows 2000 or XP installed. 2. A web browser (Internet Explorer 5.5, 6.0, Netscape 7.1 or later) with JavaScript enabled. 3. A straight-through or crossover Category 5 Ethernet cable to connect your PC to the switch. But I think that it could be OK to try with my Linux Debian Lenny and Iceweasel, here is what I got, when I finally managed to get an IP from the switch. Here the zoomed image. As you can see there is no support for Linux, and for me that is sad, as both Cisco and Linux helped a lot to made the Internet what Internet is now. Maybe I am using an old IOS, and the new one does support Linux, but at least this one not, it was even...

External Laptop Battery

If you need to work hours with your laptop where there is no place to plug it, for example at the airport while waiting for the endless time between one fly and the other. :( .. You may be needing something like this, the good thing about this external battery is that it is universal, the bad thing is that is another package to worry about, and to carry also, but almost everybody is carrying two Laptop s batteries. Its specifications are: weight = 0.75 kg dimensions = 298 x 216 x 15 mm power = 70 VA/hour And it is a Li-polymer battery so you will not have to worry about discharging, to charge it again it has no "memory" effect, and it is designed to last for 2 to 4 years. It should add some three hours of work, with WiFi on, and working hard, but of course depending on your Laptop, and the voltage it may needs the more voltage the less time it will last. The output voltage range between 15,16,18,19,20 volts, so as you can see it is universal.

Fine tunning your polipo cache
