Install Spotify on Debian Testing (Wheezy)

If you follow the instructions on the Spotify Linux Preview website to install Spotify on Debian Wheezy, you will get the following error from apt:

The following packages have unmet dependencies:
spotify-client : Depends: libssl0.9.8 but it is not installable

The problem is that Spotify is hardlinked with libssl0.9.8, and the Wheezy repos only have libssl1.0. This is a very easy problem to rectify. Just go to the libssl0.9.8 package page for Squeeze and download the appropriate package for your architecture.
download_libssl
Then install the package, like so:

sudo dpkg -i /path/to/package.deb

(of course replace "/path/to/package.deb" with the actual location of the libssl0.9.8 package you just downloaded)

Now you should be able to install spotify-client by following spotify's instructions:

# 1. Add this line to your list of repositories by
#    editing your /etc/apt/sources.list
deb http://repository.spotify.com stable non-free

# 2. If you want to verify the downloaded packages,
#    you will need to add our public key
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 94558F59

# 3. Run apt-get update
sudo apt-get update

# 4. Install spotify!
sudo apt-get install spotify-client

Which Architecture

A common question a lot of new users have is, what is an "architecture" and which one does my computer use?

If you really want to know what is meant by computer architecture, then there's always wikipedia to learn from.

In the context of Linux users, I usually hear this question in a couple different scenarios:

Q: I want to install a Linux distribution, which version do I need, 32 or 64 bit?

A: You can't go wrong by installing a 32 bit distribution, because hardware designed to run 64 bit software, can run 32 bit software with no problem. Here's a list of 64bit CPUs. If your CPU is on your list, you might want to use a 64 bit version of your distro instead. A little tip: If you really need to ask this question and the answer confuses you, just go with the 32 bit version.

Q: I already have Linux running on this machine, now I want to know if it's a 32 bit kernel, or a 64 bit kernel.

A: Easy!

uname -m

will give you the architecture of your kernel. i386, i686 are 32 bit, and amd64 is 64 bit!

Q: Okay, how do I find out if my CPU is 32 or 64 bit, regardless of what Linux kernel it's running?

A: There are actually a few ways to do this:

lscpu

displays cpu info, and will tell you the architecture of your CPU and if it can use 64 bit op-mode. This is probably the easiest way.

Another way:

grep lm /proc/cpuinfo

searches for the "lm" string in /proc/cpuinfo/. If it's found, that means the CPU is capable of 64 bit mode. Btw, lm means "long mode".

Linus Hit by Bus!

The fateful day has arrived - Linus Torvalds, creator and maintainer of the Linux kernel, has been hit by a bus. He has survived, but with massive brain damage. Consequently, he has decided he is no longer able to head the Linux project and has decided to apply himself to something more appropriate given his severely diminshed abilities.

Linus Torvalds will now join Microsoft and dedicate himself to the development of Windows 9.
