A friend of mine told me about this, a web site for trading of finantial instruments. I didn't read all the docs yet. Their client tools runs only on windows - bad start :-(

The "about" section of their home page says:
"Marketiva is a financial services corporation specialized in providing traders with high quality online trading services. With a team of dedicated financial specialists and technical support personnel, Marketiva operates globally as a market maker and principal counterparty to retail traders. ... ."
My friend told me this marketiva gives the investor 5 dollars to start, closes your position automatically if you loose more then 1%.

There are other sites for trading financial instruments, like, but as he says, marketiva is a good to start because it is the one who protects most the investors. The others, as he said, are "spanking cats" ;-)

As-Rigid-As-Possible Shape Manipulation

This morning on the animation class I am taking at grad school, a colleague had shown a paper review on "As-Rigid-As-Possible Shape Manipulation" [1]. I've found that is awesome... There are many applications for this new approach on shape manipulation. There must be someone to write a inkscape extension using this technique.

GLGlobe - free OpenGl Globe-Earth simulation for linux

I was googling around for some code to use on my next work for the visualization class at grad school, and I found this interesting code. web site says it could not compile on my machine, but it did! The code is not too much complex and this could be used in a variety of ways.

Here is what I've got:

Converting charset enconding of a bunch o .tex files

A friend of mine came to me asking for a simple way to convert the charset encoding of a bunch o LaTeX files. He had all his files in the UFT-8 encoding and he wanted to convert all of them to "latin-1" (ISO-8859-1).

So, I saved all the files he sent me in the same folder, opened a terminal shell window and typed the following command line:

ls -1 *.tex | while read line ; do iconv -f utf-8 -t iso-8859-1 $line -o "latin1_"$line; done

And voilĂ , they were now encoded with ISO-8859-1.
