Howto get the rt2870 Wifi 802.11abgn chipset to work with Intrepid Ibex
sudo apt-get install build-essential
Create a directory in for example your home directory to keep all the files.
cd ~/
mkdir rt2870
cd rt2870
Now retrieve the driver
wget http://www.ralinktech.com.tw/data/drivers/2008_0925_RT2870_Linux_STA_v1.4.0.0.tar.bz2
Extract the compressed driver directory and files.
tar xvfj 2008_0925_RT2870_Linux_STA_v1.4.0.0.tar.bz2
Enter the directory and edit the config.mk file so that the driver will support NetworkManager
nano os/linux/config.mk
Change the following part
# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=n
# Support Native WpaSupplicant for Network Magang
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n
to this
# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=y
# Support Native WpaSupplicant for Network Maganger
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y
Compile and install.
sudo make
sudo make install
Edit the Ralink settings file to your liking.
sudo nano /etc/Wireless/RT2870STA/RT2870STA.dat
This is what mine looks like without the passwords and accesspoint.

I think the important part of my changes is this.
AuthMode=WPA
This was what I had to change to make the driver work with NetworkManager.
Now make the driver load at bootup
sudo nano /etc/modules
and add this line to the the file.
alias ra0 rt2870sta
My /etc/modules looks like this.
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
fuse
lp
sbp2
#ndiswrapper

alias ra0 rt2870sta
# Added for Nero Linux device access
sg
Add an ugly fix to make the ra0 interface come up during each boot.
sudo nano /etc/init.d/rc.local
and add these lines to the end of the file
ifconfig ra0 inet up
sudo /etc/init.d/NetworkManager restart
Reboot and it should work. It did for me.

Howto Add The Trash to Your Ubuntu Desktop
* Run in terminal: gconf-editor
* enter your password into the "Password For...." area
* Navigate apps \ nautilus \ desktop
* On the right side, you will see an option named "trash_icon_visible"
* Check the box next to the above said option
* exit out of gconf-editor, remember to save your work before you leave
Thats it, you should now see a big bin on your desktop, similar to the gnome-panel applet icon. I am sure this will help anyone transition from Windows to Ubuntu.

Howto Schedule Bittorrents to Automatically Download in Ubuntu
1. We need to make sure that the relevant software is installed on our system. To do this we start up Synaptic Package Manager
System → Administration → Synaptic Package Manager
and search for 'bittorrent'. Select 'bittorrent' from the options and click 'Apply' to install it with all of its dependencies. If you've already got bittorrent installed then it will already be selected in the list and you won't need to perform this step.
2. Next we need to create the directory that we will download our torrents into. You can use any directory that you have permission to use for this this but a sub-directory in your home directory will often make things easier. For this tutorial I will be using a sub-directory in the user's home directory called 'torrents'. To create this directory simply navigate to your home directory
Places → Home Folder
right click on some empty space and select 'Create Folder'. Name this folder 'torrents'.
3. To automate the task of downloading torrents, and stopping the downloads at an appropriate time, we are going to create some very simple bash scripts (For more on bash scripts see here). We will use the familiar graphical text editor gedit for this task.
In your home folder right click some empty space and select
'Create Document' → 'Empty File'
Name this file 'bittorrentstart'. Perform this task again to create another file and call this one 'bittorrentstop'. You can place these files anywhere you like, perhaps in a directory called 'scripts', but this tutorial will assume they are in your Home directory.
Double click the file 'bittorrentstart' to open it and paste in the following information
#!/bin/sh
# Start Downloading Torrent Files!
cd
nohup btlaunchmany /home/Your_User_Name/torrents/ > torrent.log &
tail -f torrent.log
Make sure you change the 'Your_User_Name' to your user-name. Save this file, open 'bittorrentstop' and paste in the following information
#!/bin/bash
# Stop Downloading ALL Torrent Files!
killall btlaunchmany
4. The second part of automating the downloading of torrents is to tell our computer when to execute the start script and execute the stop script. To do this we use a tool called cron . To make the editing of cron entries simple we are going to create a text file that we will edit in gedit (like the bash scripts above) and then append it to our cron entries.
While in your Home directory right click on some empty space and select
'Create Document' → 'Empty File'
Name this file 'cron.txt'. Double click this file to open it and enter in the following information
# Start BitTorrent Download Script
05 02 * * * sh /home/Your_User_Name/bash_scripts/bittorrentstart.sh
# Stop ALL BitTorrent Downloads Script
55 11 * * * sh /home/Your_User_Name/bash_scripts/bittorrentstop.sh
Be sure to enter your user-name in the required fields. This setup will start the download start script at 2:05am and start the download stop script at 11:55am. These values will likely not suit you so you need to alter them. To understand the format of cron entries picture five asterisks at the start followed by your command. Something like the following
* * * * * sh /home/Your_User_Name/bash_scripts/bittorrentstart.sh
The first asterisk represents minutes, the second hours, the third days of the month, the fourth is the month, and the fifth the day of the week. The allowed syntax is
minute 0-59
hour 0-23
day of month 1-31
month 1-12 (or the month names)
day of week 0-7 (0 or 7 is Sun, or use the weekday names)
Save this file and start up your terminal emulator
Applications → Accessories → Terminal
Enter in the following command
crontab cron.txt
To verify that this was entered into your cron entries properly enter in the following command
crontab -l
5. Now that we've installed the relevant applications and told the computer to execute the appropriate tasks at the appropriate times all we need to do is save our *.torrent files into the bittorrent directory we created earlier and wait. At the appropriate times they will be downloaded into their own sub-directory without you even being aware.
6. In the bittorrentstart script we created earlier there is a command to create a log file. This file records the activity of the torrent downloads. This file, called 'torrent.log', will be found in your Home directory. You can simply open this file to check on the status of your downloads. A sample line from this log file is
/home/Your_User_Name/torrents/torrent_name: Spd: 34.0 K/s:18.2 K/s Tot: 171.2 M:61.1 M [18:10:07 76%]
All: Spd: 34.0 K/s:18.2 K/s Tot: 171.2 M:61.1 M
What all of these entries mean is beyond the scope of this tutorial but you can easily recognise your connection speed and the percentage finished of your torrent downloads.

Howto install JS3tream and backup to Amazons S3
JS3tream was written to provide easy streaming of data to and from Amazons S3 data storage service. JS3tream is NOT a backup solution by itself. But, coupled with tar or zip, JS3tream provides a very powerful backup solution.
Install the Sun JVM using the following command
sudo apt-get install sun-java5-bin
You will need the zip/unzip utility to extract the JS3tream utility
sudo apt-get install unzip
Go to the JS3tream web site, and download the latest zip file. Extract this file to a directory of your choice. Eg /usr/local/bin
cd /usr/local/bin
unzip js3tream-0.6.2.zip
Test to make sure both java and JS3tream are correctly setup. Start by going to the directory you put JS3tream.
cd /usr/local/bin
Make sure java is correctly installed. I happen to have 1.5.0.11
sudo java -version
java version "1.5.0_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode)
Test that JS3tream can be executed.
sudo java -jar js3tream.jar --help
JS3tream v0.6 - December 17, 2007
Protected under the LGPL
Copyright (c) Shane Powell 2007
http://js3tream.sourceforge.net
At this point JS3tream should be correctly installed. Now, it's simply a matter of following the examples and howtos on the JS3tream web site.

Howto install JS3tream and backup to Amazons S3
JS3tream was written to provide easy streaming of data to and from Amazons S3 data storage service. JS3tream is NOT a backup solution by itself. But, coupled with tar or zip, JS3tream provides a very powerful backup solution.
Install the Sun JVM using the following command
sudo apt-get install sun-java5-bin
You will need the zip/unzip utility to extract the JS3tream utility
sudo apt-get install unzip
Go to the JS3tream web site, and download the latest zip file. Extract this file to a directory of your choice. Eg /usr/local/bin
cd /usr/local/bin
unzip js3tream-0.6.2.zip
Test to make sure both java and JS3tream are correctly setup. Start by going to the directory you put JS3tream.
cd /usr/local/bin
Make sure java is correctly installed. I happen to have 1.5.0.11
sudo java -version
