I recently discovered a very useful tool: xrandr. This command allows you to reset your screen resolution, which comes in very handy when some buggy app changes you screen resolution and doesn't set it back. It saves logging out and in again or even having to use Ctrl + Alt + Backspace! (More)

The bash shell is just amazing. There are so many tasks that can be simplified using its handy features. This tutorial tells about some of those features, explains what exactly they do and learns you how to use them.

Although I don't like it at all, I'm simply not able to spend much time on this site because the many things that need to be done for school are calling me. I'm afraid that you'll have to wait a little longer for the promised bash tutorial. Anyway, if you have a great idea for a tutorial or if you have feedback on, for example, the advertisements, please place a comment!

Well, this offer has now been suspended, as the trip to Africa was already made. It was good, impressive and fun. It made me realize that those slums really are there, which was quite a hard feeling, but at the same time, it was great to be able to help the local people a bit, and to support the organization (Victory4All) that is active in the slums we went to. I thank God for the experiences I had, and I hope that many more people will leave their comfort zone and reach out for people living in such circumstances. God bless those who already do.

First of all: the money will not go to me, but to a trip to Africa this summer where 21 young people (including me) will help building a school, give the poor children over there some great days and repair houses in the slums. You can find more details on this project in the full version of the post.

About the text links: if you donate as little as $10 to the project, you will get a text link to the specified website in the Text Links column on the left (read more about it in the full version of the post). Of course, you're allowed to donate more =), but you will only get a single text link. If you want two text links, donate $10 or more two times. Payment is done using Paypal. Note: I will not accept every text link. Don't even try getting a link to a site containing things like gambling or adult content. If I don't think the specified website suitable to link to, I will decline the payment.

You can also just donate, without receiving a text link. To do that, simply don't specify an URL in the description box (you may fill in a message, like "Good luck on your trip!" or something like that).

I am currently working on a tutorial full of useful bash tricks. However, little time and much tutorialwriting don't go together that well =). You will probably have to wait for the tutorial a few days. In the meanwhile, please comment on what tutorial you'd want me to write after that bash tutorial. I am pretty much out of tutorial subjects, and I would like to know what you would like to see on this site. Thanks in advance, and remember that you can subscribe to the RSS feed (see the bottom of the right menu bar) if you want to keep up with the new postings on this site.

This tutorial handles about the usage of the wonderful media player MPlayer. It explains several options, lists some useful keyboard shortcuts and handles about tips and tricks that can be used to enhance your multimedia experience.

Linux text files and Windows text files differ from each other in an important aspect. They have a different way to indicate the end of a line. Sometimes, when opening a text file on Linux, you see a ^M here and there. This means that the text file contains Windows-like line breaks. This solution describes how to convert a Windows-like text file to a Linux-like one, and the other way around. (More)

The commands diff and patch form a powerful combination. They are widely used to get differences between original files and updated files in such a way that other people who only have the original files can turn them into the updated files with just a single patch file that contains only the differences. This tutorial explains the basics of how to use these great commands.

To the people coming in from http://www.linux.org.ru/:

You know, I think it's quite a good idea to discuss my tutorials and say what you think about them. However, if you are doing this in Russian at linux.org.ru, you aren't quite helping me to improve this site's quality, no matter how good your suggestions are. Therefore, I'm asking you: please place a comment here, too (in English)! I can't read Russian, and Babelfish's translation isn't that readable. Thanks in advance and enjoy the tutorials! 

Sometimes, the typical sequence to compile a program doesn't work. It starts spitting out all kinds of errors and seems to do everything but compiling that annoying program already. What to do then? This tutorial describes how to get rid of many frequently occuring errors during a typical Linux compiling sequence.

Note: You should only compile software when you really need to do it. Compiling can be dangerous to your Linux installation. If you want to install some software, please look for a precompiled package (like a .rpm or a .deb) first. If you really need to compile, do it with care.
