How to set up NX server free on your Linux box?
4What is the NX server?
The NX server and client application is developed by the Italian company NoMachine and provides a way to efficiently and securely access X-server based GUIs.
It compresses the X-server rendered screens and enables the client to access it via SSH. Thus making it possible to even access your remote linux server using an dial-up internet connection conveniently.
Is it expensive?
You can download and use the NX server and client for free. The free version is restricted to 2 concurrent client connections at the same time. If you need to set it up for more users you’d need to buy a license.
How do I get started?
If you use Ubuntu or Debian, you need to download the nxserver, nxnode and nxclient DEB packages and install them.
Download all 3 deb packages which suite your distribution (x86 or x64 packages are available) to your server from here:
http://www.nomachine.com/download.php
Now first install the nxclient package and then the nxnode and last but not least the nxserver. Make sure to meet the dependencies.
The packages get installed in the directory: /usr/NX/
After you installed all three packages you just have to start the nxserver by typing:
sudo /usr/NX/bin/nxserver --start
Basically you’re done now! That was easy, right?
Now it’s time to install the nxclient on your client machine and set up the connection using the wizard which appears when you start the client for the first time.
If you have any questions regarding further settings just comment on this post!
How to stay informed about the BP oilspill?

Worst case scenario
The explosion of the “Deepwater Horizon” drilling rig on April 20, 2010 triggered the worst oil disaster in the history of the United States. 11 workers died and 17 were injured at the explosion. Until BP managed to cap the gushing oil wellhead on July 15, 2010, 90 million to 180 million gallons of crude oil were released into the Gulf of Mexico.
How to stay informed?
Due to the massive amount of information which mainstream news media spread, people all over the world watch and comment this horrible event.

How to capture video streams using VLC player?
2
What is VLC?
VLC is a free, multi-format and open source media player application written by the VideoLAN project.
But playing your favorite movie or audio files is not the only thing it can do. It is also able to encode and stream audio or video content.
The other nice fact is, that it is running under a multitude of operating systems like Microsoft Windows, Mac OS X, Linux, BeOS and BSD.
What types of streams can I record with it?
With VLC you can easily record MMS, WMF and ASF streams.
Tell me how already!
To record a stream you first need to get the streaming URL. You can mostly do that be right-clicking the video picture and selecting “Properties…”:
Look at the “Location” info on the Properties dialog:
Mark and copy the link by pressing CTRL+C and start up VLC. Now go to Media -> Convert/Save… click on the Network tab and paste the URL you copied from the stream earlier into the text box. It should look like this:
The next thing you have to do is to click on Convert / Save and you will see this dialog:
First, enter the file name of the destination file including the extension, e.g. NasaTV.asf
Tick the “Display the output” check box to see how the stream looks like while you’re recording. Then you select the Profile, which defines how the file format will be recorded as and click “Start”. I usually use “Video – WMV + WMA (ASF)”.
Now you will have to be patient, because it can take up to 1 minute, depending on your internet connection, for VLC to start displaying and recording the stream. When you think you have recorded enough, just click on the stop button to close the file you’re currently recording into.
You can download the VLC player on the official website.
How to remotely fix computer issues?

Average users…
Most of the people nowadays turn on their computers and just start to browse the Internet to read news, update their Facebook status or check their emails. They don’t really care about how things work. But then, someday, they run into a problem. Some application doesn’t start anymore or suddenly something looks different and they start to panic.
Due to the fact that an average computer user doesn’t know and maybe doesn’t want to bother with the basic structures behind applications or even an operating system they often seek help from expensive IT experts who charge a lot of money for a simple task or just a quick change of some rogue setting.
