One of the first thing any advanced user should do after installing Android on their mini-pc is to install an SSH Server to enable remote-access from a computer for faster and easier tweaking, one can simply opt for an free SSH Server app from Google Play like SSHelper for a no frill, click-n-install SSH access to your Android box. However, if you prefer a GUI-less access with FULL-ROOT privileges from both WinSCP and Putty follow the tutorial shard ahead.

The beauty of Android is that it allows users the flexibility to tweak things to the extent that their devices can run other operating-systems. Ubuntu Dual Boot Installer takes advantage of this and has now released an app allowing users to run Ubuntu and Android on a single device as a dual-boot system. A user can install and use fully functional Android and Ubuntu images and switch between them easily, on each-side, an app with a simple user interface enables them to boot back and forth at the tap of a button.

Moving ahead with it's goal to converge the desktop and mobile computing environment, Canonical the developers behind the popular open-source, Linux distribution "Ubuntu" have now launched the crowd-funding for the first-phone to feature their Ubuntu Mobile OS announced earlier.

Named "Ubuntu Edge" the gadget is backed by some powerful hardware specifications like fastest available multi-core processor, at least 4GB of RAM, and massive 128GB of storage the phone will also feature elegantly finished textured amorphous metal casing made from a single sheet, a 4.5 inch screen with amazing dynamic range and color accuracy for maximum clarity protected by nothing else but a pure sapphire crystal glass which is so hard that only diamond could scratch it. On the software front the phone will feature dual-boot between Ubuntu Phone OS and Android, and will convert into a fully integrated Ubuntu desktop PC when attached to an external screen. Don't miss the "Ubuntu Edge" teaser and introduction videos posted below.

If Apple iOS, Google Android, Microsoft Windows Phone, Blackberry OS, Symbian, Mozilla Mobile OS, Nokia MeeGo and Sailfish does not satisfy your need for the perfect, most hackable and customizable mobile operating system, here is an exciting "open-source" candidate with some promising features from the leading Linux distribution - Ubuntu.

Ubuntu's developer Canonical has announced their entry into the smartphone business with first public glimpses and features of upcoming Ubuntu for Phones. The Linux-based operating system will offer users an seamless experience on Desktop, PC and Mobile with some exciting features and an "android compatible kernel" so existing Google Android users can simply install and use Ubuntu on their phones. While Ubuntu for Phones will be available in 2013 for users to install on existing hardware, handsets powered by the OS will hit shelves in 2014. Canonical released an extensive video preview and this looks really promising - have a look yourself below.

If we look at hardware specifications of today's smartphones they are more then capable to run an powerful desktop or laptop computer, so wouldn't it be a "smart idea" to use a single smartphone hardware all across your devices like tablet, laptop and desktop ?

The idea of a single brain multi-utility computing device like RollTop is not new, but new startup NexPhone is not only modern, practical and innovative but it takes this to an all new level. By using a single brain (hardware to store and process your data) it not only makes things more affordable but also more manageable. Users will no longer be needed to buy different internet subscription plans and services for multiple devices, but also will have all there files, music , videos and software's at a single location without needing the cloud to synchronize in between.

The idea is to have a NexPhone which would be an Android smartphone coupled with Ubuntu, which docks with connectors like tablet, notebook, laptop or desktop computer to provide the device functionality of your choice. The startup needs crowd-funding to get into production which seems sufficiently feasible, a nice introductory video and other related information after the jump.

Want to enjoy the popular desktop Linux OS Ubuntu on your Android powered mobile device, it can't get easier than this - the free "Ubuntu Installer" app from Android Market. The application allows users to install and run "Ubuntu" inside Android - The market application installs an customized Ubuntu 10.10 image optimized for the ARM processor allowing users to run a full Ubuntu system within android. The great thing is users can make calls, text, and use other android features without having to reboot their phones.
