Many Linux distributions including the official Debian based Rasbian distro for Raspberry Pi makes uses of X11 or XServer windowing software to render the user interface, the problem is X11 is not optimized to use the graphics core of RasPi efficiently resulting in degraded lagged window composition. The Raspberry Pi core team has now decided to bypass X11 completely and move over to the open-source Wayland composition protocol.

The overall results are really exciting, while still in development the team prepared a video demonstration comparing the two and results are really promising. The video comparison and links to details including how to install the technology preview on Raspbian are shared below (click Read more).

When is comes to mobile devices I have always adored the fast and sleek Windows 8 Metro UI, couple that with some excellent tablet designs and versatile form factors and you should have an winner. Sadly, that has not been the case and Windows 8 tablets are struggling to keep pace with it's main competitor - the Apple iPad. To revive competition, Microsoft has once again waged an advertising attack comparing the two head-on pinpointing what Apple iPad lacks, do watch the video below (click read more).

While users can easily install and use multiple operating-systems on Raspberry Pi using BerryBoot, the beauty of an removable media card as operating-system loader is the simple plug-n-boot ease of use. The official Debian Linux port is the most widely used and supported distribution for Raspberry Pi, but specialized OS like RasPlex, Xbian and Raspbmc are also available for download with more and more Linux distributions getting ported for the platform by the developer community. Adding another excellent addition to the ever growing list of dedicated, RPi optimized builds of various Linux distributions; Fedora joined the club with release of Pidora - a Fedora Remix optimized build for the Raspberry Pi computer.

Pidora is an RPi optimized build of Fedora (Fedora Remix) featuring software packages from the Fedora Project compiled specifically for the ARMv6 architecture for use on the Raspberry Pi. Unique features of this build are Graphical firstboot configuration (with additional modules specifically made for the Raspberry Pi), Compact initial image size with auto-resize for maximum storage afterwards, unique feature allowing IP address information readable over speakers and flashed with the LED light for true headless mode on setups lacking a monitor or display, easy package management using Yum, included support for programming languages (like C, Python, & Perl) and libraries capable of supporting external hardware such as motors and robotics (via GPIO, I2C, SPI) out-of-the-box.

Apple holds the trademark for punchline "There's an app for that" and rightly so there is an app for almost everything one could imagine using technology to help them with. To take things to another level altogether, an Indian startup "Biosense Technologies" has came up with an innovative iPhone app which lets users do Urine medical analysis at home at a fraction of cost and time of lab tests.

A chemically active urinalysis reagent strip or "dipstick" is used to test urine samples, the chemically coated patches on these pads change color when dipped in urine - reacting to the contents present in the sample. The color change, that happens gradually over a specified time period after dipping the strip, helps identify the concentration of different analytes in urine. The uChek system makes use of your smartphone camera and intelligent software to function similar to most commercially available semi-automated urine analyzer machines.
