Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system. We tested the best Ubuntu Bitcoin Clients for you (Multibit, Armory and Bitcoin-Qt). Here you'll find a short review with some installation instructions.
Being free, open-source and covering the same range of features, GIMP is undoubtedly a great alternative to Adobe Photoshop. Furthermore GIMP gives you the possibility to open and edit PSD files out of the box, so that you can jump right in after installing the application. In Ubuntu you can install GIMP from the Ubuntu Software Center. Enjoy!
Whenever you take screenshots using the default screenshot tool of Ubuntu, the image does not look as good as the screen itself (the quality is deteriorated).

If so, I recommend you to use the derivatives Xubuntu or Lubuntu that use much less resources. While Ubuntu 13.04 is said to use around 320 MB RAM, XUbuntu 13.04 and LUbuntu 13.04 are said to use around 160 MB and 103 MB respectively.
If you are using Ubuntu and you want to run an application which is not available on Ubuntu, you can use WineHQ to run Windows applications.
