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

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


How do i connect Mini-PCI express with PCI-X1 cards?

October 9, 2011 Leave a comment

Mini-PCI express slots are same as PCI-X1 cards, most of you think that is true. But for some cards its not, because in 90’s the specification was revised and there is some BUS issues involved.

1. To power the mini-pci express cards you have to put external ATX power which can feed 12volt, 5volt (check the amps too)

2. When the ATX power is supplied it will boot but because of incorrect BUS issues it may not be recognized by OS/BIOS.

So, finally the best move is to go straight PCI-X1 slots. If you have solution post here your research.

Practical in Ubuntu: setserial, minicom application requires.

Test my console is it DB9 or USB?
