Giant Sony, Quality Sony uses finally Linux, never discovered by nobody ?

Sony ericsson: has there own operating system calls Xperia which is actually Android, before they were using Windows mobile platforms

Sony: themselves obviously is using Linux but they kept top secret, my guess is its either using JavaOS or Linux

– Great to know if somebody care to tell!

Ubuntu is now running on top of Android. Soon there will be no more NDK/SDK requirement. Android made a mess mistake for GCC developers. Everything in past need to use NDK/SDK to retype every single lines to JNA code, which is idiot implementation actually of Android.

Android Ubuntu will then allow GCC

– Tizen linux from Intel, Samsung will soon release there dragon Linux with GCC support to take-over Android, IPhone

@TODO: Its all about color. And its all about pixel to micro pixel as RGB/YUV format.

How do i make sure my Linux operating system audio drivers are working. But hardware is defected for line in or mic in?

In my motherboard i have line in/mic in. But when i boot my linux i can not get audio in. I have tried all detectors but none is helping.

1. Get a speaker box or head phone

2. Put the head phone jack to the motherboard mic in/line in

3. Grab audacity software and knock your speaker you will see frequency

– if yes, Linux and its drivers are not the issue, culprit is the microphone+hardware

– if no, fix your audio libraries
