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!
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.
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). So if would like to take high quality screenshots, you have to install an advanced tool. Our suggestion would be to use the screen capture tool Shutter. Shutter is a feature-rich screenshot program for Linux based operating systems such as Ubuntu.

If you have an old computer with limited resources you might have problems to run the recent Ubuntu releases 12.04 LTS or 13.04 smoothly. 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.
Although there are quite a number of changes, the Ubuntu 16.04 LTS Desktop release is once more rather an evolution than a revolution. This is of course something many of us appreciate about Ubuntu, because it allows a smooth transition between the Long Term Support (LTS) releases.
