External harddrive speed woes

Posted 02-22-2011 at 01:31 AM by William (Dthdealer) (Whaling the FOSS)

A few minutes ago I was preparing to distribute video encoding of files on my portable harddrive across multiple computers in the house. Just to get the quality and codec settings right before I finished, I started encoding one of the videos on only my main computer.

I'm glad I ran this test.

At first when encoding, I noticed the second CPU wasn't being used. I thought perhaps the encoder wasn't designed to be multi-threaded, but that would be ridiculous. I decided...

OOo 3.3 How to???

Posted 02-21-2011 at 09:11 AM by teboil12

Have Ubuntu 10.10. Am a newbie.

I just uninstalled my Open Office 3.2, to install Open Office 3.3 instead. That's what I did, sudo add-apt-repository ppapenoffice-pkgs/ppa. after that sudo apt-get update, after that sudo apt-get install openoffice.org. Everthing seemed OK.

Could anybody...

batch resize images using find, xargs and convert

Posted 02-20-2011 at 04:30 PM by dr_agon

applies to: linux, find, xargs, convert, image processing

'convert' command, which is a part of ImageMagick package can be used for image resizing, but it lacks ability to process multiple files (in version of ImageMagick 6.5.7-8 2010-12-02). Instead of writing a shell script you can use find and xargs commands to collect filenames and invoke convert with one filename at a time, like this:

Code:
find -iname "*.jpg" -printf "%f\0" \
 | xargs -0 -I {} convert

...with each new kernel, it seems.

A while back, when I was still running with kernel 2.6.34/35 (and earlier) on my lappy, PowerTOP would show idle power usage anywhere from 10.x W to the occasional dip into the single-digits. Now on kernel 2.6.37, it never goes below 11 W, and sometimes hovers around 12...this annoys me, because it does take a hit on my lappy's battery life (what once was 4+ hours is now 3- ).

The backlight is always at the lowest level when...
