Wubi - Install Linux into Windows

With Wubi you can install Linux in a working Windows System. If there's a moment when you don't like Linux anymore, you haven't to delete the whole partition, you can uninstall Linux like a normal Windows application.

To install Wubi, you have to put your Linux CD into your drive and you have to press "Install into Windows". Now you were asked about the username and password and how many disk space Linux is going to get.
If this is finished, all necessary files were copied from the CD on your computer and you have to reboot.

Now you get a new boot screen. Either on 30 secs windows boots from alone or you can change to Linux.

For me this is a very good posibility to use Linux, because I can't install Linux on a second partition.

You can download "Wubi" here:

OpenSSH Server Installation

In fact it's very easy to install OpenSSH in Linux.

To install OpenSSH enter: "sudo apt-get install openssh-server openssh-client" (without "")

To start the SSH Server enter: "sudo /etc/init.d/ssh start"

To close the SSH Server enter:"sudo /etc/init.d/ssh stop"

And at last to restart the SSH Server enter:"sudo /etc/init.d/ssh restart"

To access to your SSH Server for example from Windows, you can download a little tool, called "Putty".

PS: I used Ubuntu to install SSH.

Mydrive

I searched for a free on-line hard disk and I found http://mydrive.ch.

- You get 2GB disk space
- You can upload files via your web browser or you install a network hard drive on your local computer.
- You can install a guest access and pick single folders, which should be visible for the guest.

I use the on-line hard disk for backups and listening to my music, from everywhere I want.

Attention: I wouldn't make MP3 files visible for the guest.

Visible-/ Invisible-List in ICQ

Some people asked me about the Visible-/ Invisible-List of ICQ. But I thinks it's very easy:

If you put somebody on your Visible-List, the user can see you always. It doesn't care if you're on-line or invisible.

If you put somebody on your Invisible-List, the user can't see you anymore. There's no difference if you're on-line or invisible, he can't see you.

At last, if you put your status on invisible, only your Visible-List is able to see you on-line.

Trillian

To know what I'm talking about you should download this program:

http://www.trillian.im/

With this program you can use Twitter, Facebook, ICQ, Skype, Windows Live Messenger, Jabber or manage your emails. In my opinion this is a very brilliant program, because you needn't 1000 windows to manage all your accounts. I found this program on fortune on Twitter.

This program has many functions and is also well looking. You have different ways to display the chat window. Also you can adjust different skins.
But the program has also another site. The settings-menu is a little bit complicated and it's useful to have a small basic knowledge.

In the next time, I'll install Trillian in Windows 7 and after I  tested it there, I will write a blog post about that.
