There is a nice package, psensor and it can be install as easy as
$ sudo apt-get install psensor
So just launch the application from the terminal, then see the screenshot below.
On the left, I have configured three temperature to be plotted. Because hardware in different computer are different, so you can enable plotting for different hardware. On the right, it is the psensor preferences, and I have enabled checkbox for Launch on session startup and Hide window on startup.
Next, we will install a stock applet as a favor for a friend. Because in debian, this is not available and now we will download from ubuntu repository. Point your browser to https://launchpad.net/~ce3a/+archive/ubuntu/indicator-stocks/+packages and download latest version of indicator-stocks. As of this writing, I'm installing indicator-stocks_0.2.4-0ubuntu1_amd64
user@localhost:~/Desktop$ sudo dpkg -i indicator-stocks_0.2.4-0ubuntu1_amd64.deb

As you can read above, there is a dependency problem during installing indicator-stocks. So just use apt-get install for the remaining package. It should be simple process to resolved that using apt. So it is finally installed, check the screenshot below. You can configured a few symbols, it is from finance.yahoo.com.
That's it, from the past and in this articles, I hope your desktop should present as much information as possible.
