sudo apt-get install fortunes-ubuntu-server 

You can now execute the command below to get random useful tips.

 ubuntu-server-tip 

You could also add this command to the .bashrc to get random useful tips every time you open the terminal!

Step 1 – Download Ubuntu MinmalCD:

The Ubuntu MinmalCD can be downloaded from the official Ubuntu website. Pick the architecture based on your needs, or the capabilities of your hardware. If you’re not sure what architecture to pick, then 32 bit is a safe bet. Download the ISO, and burn it to a CD, or make a bootable USB memory stick (I like to use UNetbootin for this purpose.)

Step 2 – Boot from USB/CD and install:

When installing the Xubuntu minmal install, I usually just go with the default settings of the installer. On the step “Software selection”,  select nothing, and move on.

Step 3 –  Post installation:

Restart the computer once the install is complete, and press “Alt + F1″ when GRUB appears, this will show you the console. Login with your username and password set during the installation. Now you have to install the actual XFCE package. This can be done by the command:

 sudo apt-get install xfce 

This is the bare minimum, you might also like to install a graphical login screen, like slim, gdm or light-gdm. I prefer to use light-gdm. You might also want to install some more packages, to add some more function. The following would give you a nice , minimal setup, adapt the packages as you wish.

 sudo apt-get install xfce4 xfce4-goodies xfce4-mixer gedit synaptic lightdm firefox totem 

That collection of packs adds a simple text editor, login manager, sound mixer, a web browser (firefox) and a media player.

The version that was compiled is the greatest stable release as of now, version 1.9.1, and was compiled by Xcode version 4.1 It was compiled and tested on Mac OSX Lion, and might or might not work on Mac OSX Snow Leopard.

Update 30/05-2012:

I have now compiled the newest version of wget, 1.13.

Wget 1.13 for Mac can be downloaded here.

The older version below will still be available for those who for any reason would still like to use this.

Update 18/08-2011:
The binary has been confirmed to work on Snow Leopard, but you might have to mark it as an executable. The can be done via the terminal, and the command “chmod +x wget”.

Wget for Mac can be downloaded here.

$scp report.doc username@remotehost.com:/directory/subdir

This code will connect via a secure encrypted channel. Change “host.net” to either to the domain or ip adress where you wish to store your files. You will also have to supply a username. In this case, the file will be written to the “/directory/subdir”, relative to root. Note that the you specify needs to have write access to the folder you’re trying to write to. It’s not recommended to use root user as the user for the “receiving” end.

The following code shows how to copy an entire folder recursively, IE including sub dirs.

$scp -r /path/local/directory username@remotehost.com:/path/remote/directory

I’ve now shown your how to copy a file or folder from your computer to a remote host, but what if you want pull a remote file or folder?

scp -r username@remotehost.com:/path/remote/directory /path/local/directory

You can also copy a remote file/folder to a remote host:

scp username@remotehost1.com:/path/remote/host1/file.txt username@remotehost2.com:/path/remote/host2/

You can also compress files on the fly in order to minimize the data needed to be sent. Note that this method doesn’t work well with file already compress, like a video file. It does, however, work very well for text based files or some database setup.

scp -C /path/local/directory username@remotehost.com:file.txt

sudo apt-get install iotop

iotop can only run under a Linux 2.6.20 or later kernel built with the CONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING and CONFIG_VM_EVENT_COUNTERS build config options on.

The program can easily be installed using the standard repos of most distributions based on Debian, such as Ubuntu. To install NetHogs simply issue the following command in terminal:

sudo apt-get install nethogs

NetHogs is launched by issuing the following command in the terminal

sudo nethogs eth0

where eth0 corresponds to the network interface you want to monitor.

1 – The CPU can directly access the files on the RAM chips. Such can’t be done with conventional hard drives or SSDs

2 – The seek time, the time it takes to actually find where the files are located on the storage media, is inherently a lot lower on RAM chips than on mechanical hard drives.

By default Ubuntu has RAM disk that is mounted on /dev/shm/ directory. You can copy/move files to that directory and use that as the RAM disk. This is particularly useful for use-cases where you need to read or write large amounts of data fast, and further processes these. I usually use the RAM disk for reading and consolidating large amount of text divided among many files. This results in a great increase in speed for such applications.

You should not exceed the amount of RAM on your system while using this approach since it will force your PC to swap the data to the hard drive, leading to a loss of speed. System crashes might also happen when you exceed the amount of RAM in your system. It is therefore a good practice to set an upper limit of how much you can store on your RAM disk. The code below shows how this can be done.

mkdir -p /tmp/ram

sudo mount -t tmpfs -o size=512M tmpfs /tmp/ram

This code snippet creates a directory, and mounts it in the RAM. The size

argument here can be adjusted to your needs.

Long story short: I manged to Rick Roll myself. Big time.
