Gentoo Versus Ubuntu 9.04

Gentoo Optimizations Benchmarked by Christopher Smart.  Christopher also did the Gentoo: "We're Not Dead" article /interview.

Interesting article.  Looks like the GCC optimizations help Gentoo win out almost all the time.  In the game area the frame rate can be really improved by Gentoo.  However, there were some places where Ubuntu beats Gentoo by a little bit.  This was a surprise to me.  I would have expect them to be only tied at worst.  There must be something else going on. But Ubuntu winning was very seldom.

The set of bench marks used was Phoronix Test Suite by Phronix of course.

The new Ubuntu is Here! The new Ubuntu is Here!

Picture Steve Martin jumping and yelling the "The new Ubuntu is here! The new Ubuntu is here!".

Ubuntu 9.10 is coming!

this is a test

did this work?

Linux from Scratch

Starting with reading list:

Software Building Howto

His examples of source code he debug is excellent.

Press the test button for Sound Events, Music and Movies, and Audio Conferencing Sound Playback. You should hear an irritating tone.

Next set the Sound Capture to HDA ALC286 Analog (ALSA). Put a mic in the mic port on the front of the computer.

Pressing the Test button for Audio Conferencing Sound Capture yields static and a delayed sound. Hearing the delayed sound is best with a clap every couple of seconds.

Applications==>Sound & Video==>Sound Record









Record a few seconds of audio. Play back the audio and you should hear any sound recorded.

I was unable to record any sound at the mic by the Web Cam; however, mic in the mic port in front of the computer work fine.

Testing Results

HDA Intel Si3054 Modem (ALSA) Front Mic: Nothing Top Mic: Nothing
HDA Intel ALC268 Analog (ALSA) Front Mic: Sound Top Mic: Nothing
HDA Intel ALC268 Analog (OSS) Front Mic: Sound Top Mic: Nothing
ALSA - Advanced Linux Sound Architecture Front Mic: Sound Top Mic: Nothing
OSS - Open Sound System Mic: Sound Top Mic: Nothing

I was unable to get any sound out of the top mic.

Intel and Linux Support

Intel has a whole site to supporting their graphics in Linux: http://www.intellinuxgraphics.org

They also have a huge set of documents available to help the Linux driver developer: http://www.intellinuxgraphics.org/documentation.html

They are support by X.org, Mesa, Linux Kernel, Linux DRM, and BSD DRM. They don't have any funky licensing, but relay on the MIT and GPL licensing: http://www.intellinuxgraphics.org/license.html

I am very impressed.

Mounting ISO

mount /path/to/image.iso /mnt/mountpoint -t iso9660 -o loop=/dev/loop

Testing with XP ISO.

sudo mount ./WinXP_sp2.iso /mnt/xpiso -t iso9660 -o loop=/dev/loop0

The above code works.

I need to trick the system into thinking that it is accessing the CD for installing linux.
