The reason I chose a non-integer number in my title is because I'm special. Everyone has their X best things to do after installing Ubuntu, and even I did a parody spinoff on that some time back. The truth is, you don't need anything. But.
If you feel like slightly improving the quite solid vanilla experience offered by Ubuntu 13.10, you have come to the right place. Papa Dedo is going to show you a handful of useful, some more, some less trivial, tricks that should enhance your Salamander flavor. Now, without further ado, let's climb up the numerical ladder.
If you happen to have a graphics card that runs best with closed-source drivers, it is a good moment to install them right away. Now, this can be a little tricky sometimes, which is why you should definitely read my mega-golden-silver-bullet tutorial on that topic. Lots of useful info there, so make sure you exercise your click rights.
You have a good card, why not game some fella? Well, that's what Steam is for. The exact instructions for you specific flavor of Ubuntu, or Ubuntu-based system may differ slightly from one version to another. So make sure you pick the right one, and don't forget the Flash tutorials for 64-bit systems, either. It's all there, dear fellas.
Another one that demands its own piece.
You want the best media player, so get it. We shall command line now.
sudo apt-get install vlc
sudo apt-get install gimp gimp-plugin-registry
You will find this tool in the USC. It will do all kinds of magic for you, allowing you to easily adjust and tweak the Unity settings, including new themes and icons, hot corners, snapping, apps, and more.
Now that you have a tool to manage icons, do it. Faenza, here we go. You should add the official PPA first. Do note it is for Raring, but it is still fully usable here. I really love these icons. Just awesome. And you can explore a few new themes, too.
Before you do any massive pr0n and incriminate yourself before your significant other, perhaps you ought to disable the online search results in the Dash, as well as reduce the tracking of data in your apps.
If you're into CentOS and stuff, then please read below. Why, you ask? What's the connection? Why am I spamming you with seemingly unrelated items? Well, all of the below shows that even a server distro can be transformed into an amazing desktop system, beautiful, sleek and fast. Perhaps some of the stuff done below will inspire you for some additional efforts on Saucy Salamander. Luckily for you, almost every single app that requires special attention in CentOS is available by default in Ubuntu repositories.
CentOS, the first installation before going large with my Nvidia-powered laptop
CentOS ceremoniously deployed in my high-end production setup!

I could have easily split this one article into a dozen pieces, but I'm not so hungry for pageviews to compromise on your experience. I did write a bunch of these as individual articles, only because they are too long or important not to be standalone. Other than that, it's all good.
So no, you do not get 12.7 tips. You get nine top-level items and probably forty or fifty tips, spread across a dozen more articles. If you're really diligent, then you will gain yourself a handsome bunch of knowledge by the time you're done reading. Hopefully, this article won't just be a toasted slice of humor, but you will also use it to better your Ubuntu experience. That would be all. We might have another article coming soon, addressing other systems, maybe Xubuntu, maybe Mint, who knows.
