Getting Bamboo to work on Ubuntu
Wacom is very well supported on Linux but to make it to work with all the features you need to build the driver.
Ubuntu's Wacom wiki page has all the details .. here
Just to reiterate the steps .. here
Jarnal is a good application that you can use for taking notes. Apart from that inkscape and GIMP can be used for drawing\sketching.

Using Latex for formulas
NOTE: This is only if you are using it within OpenOffice
All of this translates to the formulas below
All of this translates to the formulas below
P_total = AC{V^2}f + {%tau}AVI_shortf + VI_leak newline
P_o = C_o {{V_o}^2}f newline
P_n = 0.5 P_o newline
I_leak = K_2 W(V over {T_ox})^2 func e^({{%alpha}T_ox over V}) newline
sum from 0 to 100 (a^2)(b^3)d newline
where, left lbrace {stack{a, contanst# b, variable # d, dynamic}} right rbrace
Using GNUPlot
GNU plot is one of the most useful applications on Linux for creating plots. GNU plot takes in data in the following format
10 324.12 12312 56
100 34231.3 2312123 67
There are three columns here, there can be any number, make sure the data is separated by a space. You can make your program write the data directly in a file, call it whatever you want to, e.g. "simout.dat"
# Fire gnuplot
# draw using the first two columns from the data file
# draw using the first and second col AND first and third col.
#draw using lines
# draw using points on the lines
# draw with a legend for the lines
# set title
# set X label
# Set Y label
# Set x and y Range
# Set log scale on X
There are so many other things that you can do with GNUPlot, which I even don't know as I am still learning how to use it.
Excellent tutorial here (that is how I got started).

set xlabel "Blocks (N)" # Set Y label

Using commands recursively with find
I copied my home folder to Windows for a backup and when I copied them back for some weird reason all the directories had executables privileges.
This is what I did to get rid of it recursively
you can pass any command as an argument to -exec. Some useful things that you can do with find are here

using wget to download websites
There are many tools available that help you download the entire website for ofline browsing but nothing can beat wget. Although it has a command line interface but it works like a song.
For more information do
and most important
$ wget --wait=5 --limit-rate=20K -r -p -U Mozilla --no-parent http://the.site.url For more information do
man wget--wait If you try to download everything some websites might blacklist you. It is recommended that you specify a wait of 20 secs before any new fetch and --wait helps you do that.--limit-rate You can limit the download speed by specifying an amount which can be expressed in bytes/sec or Kbytes/sec (with the K suffix)-r Turns on recursive retrieval-p Ensures that wget downloads all files that are required to display the HTML page correctly like pictures, PDF files etc-U Some website do not allow downloading HTML if it is not a browser. Wget gives is -U option to fake the browser.and most important
--no-parent You need to be sure that you are not downloading any other folder above the one which you want to.
