In my recent post about the handling of the security incident and compromised ISO image at Linux Mint, I said at the end that users should always verify the checksum of a downloaded image before installing it. In response I received several good comments and emails pointing out that just verifying the checksum isn't really good enough.
So what I would like to do with this post is explain a bit about what the different kinds of validation and verification are, what they are good for, and how to use them on a couple of common Linux distributions.
One of the biggest complaints about Ubuntu Unity is the lack of configuration. Yes, there is the Unity Tweak Tool (which can be installed from the standard repositories), but even with the amount of tweaks that app allows, it's been missing one highly sought after option. That option...moving the Launcher to the bottom of the window.
