ubuntu and africa explanation

Ubuntu is an African word and ubuntu is Africa themed Linux

so what is so important in Africa? beside being poor and potential for development Africa people use little of our earth resources. As seen on image emissions from Africa are low. Have met a men who fly a lot over continents and when flying over Africa at night you just don't see much lights as in other countries.

Many people in developed world today think that development means luxury. That rich mean yacht. Little rich people make use of their money to help rebuild planet. So what is truly developed person? sure one that has low impact living as seen daily in Africa and ubuntu.

human labor games comparison (gwap, google image labeler)

all games described use human labour to produce better web for example better results when looking for images

general
Google image labeler: fast, efficient, simple, can track image source
gwap:slow, beautiful, give awards (probably small presents like books), require login


description
google image labeler
brilliant game to learn language, see new images and help google image search

gwap games:
ESP game like google image labeler
Verbosity seem to be perfect for high level English speakers
Tag a tune you hear music and then tag, you have agreed wth your companion if listening to same tune, extra game where you look for most different tune
Squigl maybe good match if you have pen tablet instead of mouse - you draw lines around objects
Matchin you select pic that seems better to you - mostly clicking
Pop Video watch music video from youtube instead, when there is a talk or lyrics just look not worth writing it all down

-----

tip
use google image labelr with greasemonkey installed and darken script. search: darken lifehacker
conclusion
google imagel labeler may be better and seems like game of the century
but anyway when waitin to load you can play gwap

start and play seamless video with script

video that can be played for entertainment similar to visualisations and screensavers
digital juice and art beats are known producers of seamless video

-------------------------------------------------------------------------------------------------------------------------------------------------
killall xfmedia
sudo xfmedia -loop  -f './media/seamless/seamlessvideo.mov'&
sleep 4
#window name is Xfmedia: seamlessvideo
b=$(xwininfo -name Xfmedia:\ seamlessvideo | grep Window\ id:\ | awk '{print $4}') 
#commands to restart playback to get picture #on my pc (using virtual keyboard)
xvkbd -xsendevent -window $b -text "\t"
xvkbd -xsendevent -window $b -text "\t"
xvkbd -xsendevent -window $b -text "\t"

xubuntu install psyco to speed up nicotine (and other python programs)

1.download
http://sourceforge.net/projects/psyco/files/psyco/psyco-1.6-linux.i386-2.5.tar.gz/download

extract tar file

2.locate your python packages directory

python -c "from distutils.sysconfig import get_python_lib; print get_python_lib()"

(mine was:   cd /usr/lib/python2.6/dist-packages)


3. copy psyco directory (inside extracted directory) to packages directory

sudo cp -r psyco /usr/lib/python2.6/dist-packages

and your python code should run much much much faster

power off from terminal

script is not perfect and may need your customization. It was written so you can end programs and power off your system from terminal

code (add programs running on your system):

(ps ax | grep -v grep | grep transmission) #check if transmission is running if [ "$?" -eq 0 ]; then b=$(xwininfo -name Transmission | grep Window\ id:\ | awk '{print $4}') #get programs window id xvkbd -xsendevent -window $b -text "\Cq" #send keystroke to quit program fi sleep 1 #set firefox title to normal firefox about:blank sleep 1 (ps ax | grep -v grep | grep gnumeric) if [ "$?" -eq 0 ]; then b=$(xwininfo -name Book1.gnumeric\ :\ Gnumeric | grep Window\ id:\ | awk '{print $4}') xvkbd -xsendevent -window $b -text "\Cq" fi (ps ax | grep -v grep | grep nicotine) if [ "$?" -eq 0 ]; then b=$(xwininfo -name Nicotine+\ 1.2.9 | grep Window\ id:\ | awk '{print $4}') xvkbd -xsendevent -window $b -text "\Cq" fi sleep 1 (ps ax | grep -v grep | grep firefox) if [ "$?" -eq 0 ]; then echo firefox running, now trying to end #(using different character c) c=$(xwininfo -name Mozilla\ Firefox | grep Window\ id:\ | awk '{print $4}') xvkbd -xsendevent -window $c -text "\Cw"; sleep 1 xvkbd -xsendevent -window $c -text "\Cq"; fi df xvkbd -xsendevent -window $c -text "\Av"; (ps ax | grep -v grep | grep linuxdcpp) if [ "$?" -eq 0 ]; then b=$(xwininfo -name LinuxDC++ | grep Window\ id:\ | awk '{print $4}') xvkbd -xsendevent -window $b -text "\Cq" fi (ps ax | grep -v grep | grep vlc) if [ "$?" -eq 0 ]; then b=$(xwininfo -name VLC\ media\ player | grep Window\ id:\ | awk '{print $4}') xvkbd -xsendevent -window $b -text "\Cq" fi #send once again commands to firefox in case it wasnt running xvkbd -xsendevent -window $c -text "\Cw"; xvkbd -xsendevent -window $c -text "\Cq"; (ps ax | grep -v grep | grep transmission) if [ "$?" -eq 1 ]; then echo transmission now off, poweroff? #last resort to end firefox killall firefox sudo shutdown -P now fi

Low disk space notifications

linux low disk space notifications

Pre-requisite

In order for the pop-up message to appear, you would need to install “libnotify-bin”.

Code:

sudo apt-get install libnotify-bin

Script

The script will check the free disk space in “/dev/sda1″. It will show a pop-up message for 30 seconds when the free space is below 100MB. If the free space is below 50MB, it will show a pop-up message for 5 minutes. You should modify these parameters to your own requirement.

Copy and paste the script below to a file called “checklowdisk”.

Code:

#!/bin/sh

DISKSPACE=`df | grep "/dev/sda1" | awk '{ print $4 }'`

if [ "$DISKSPACE" -lt "51200" ] ; then
/usr/bin/notify-send -u critical -t 300000 \
'Check low disk' '/dev/sda1 is less than 50MB.'
exit
fi

if [ "$DISKSPACE" -lt "102400" ] ; then
/usr/bin/notify-send -u normal -t 30000 \
'Check low disk' '/dev/sda1 is less than 100MB.'
fi

Setting up the script

Make the script executable:

Code:

chmod +x checklowdisk

Change file ownership to root:

Code:

sudo chown root:root checklowdisk

Move file to “/usr/bin”:

Code:

sudo mv checklowdisk /usr/bin/

Set-up crontab

I chose to run the script hourly using crontab.

Edit crontab:

Code:

crontab -e

Add this line in the editor:

Code:

00 * * * * env DISPLAY=:0 /usr/bin/checklowdisk

Save and close the editor. The crontab is now configured, and the script will run at the hour.
