This week was very frustrated for me, because my Internet Service Provider (aka Hellmex) was giving me very poor service on my bandwidth and I was unable to work properly.
I was checking my bandwidth speed at internet with my browser, and I was tired to do it manually. (besides that it was a waste of time)
So, I decided to write a little script to show them what I mean when I say that they are giving me shit, when this problem came up again.
After collecting data with my script I can plot it on a nice postscript or an image with gnuplot

.
As you can see this day is not so bad. But is nice to see how is my bandwidth speed around my work day.
Update: I have released the dummy script to check the speed within the gnuplot template and shellscript to generate the graphs inside the tarball.
