That's the basic sales pitch for a new software package called Presto -- though the official verbiage doesn't dare go anywhere near that dirty "Linux" word. On its web site and in its documentation, Presto is positioned simply as a program for Windows. You download it as an .exe file and install it like you would any other application.

If you were wondering, Timbuktu isn't some mythical city with a skyline of emerald buildings housing a race of unicorn-men. It's a real place, situated in the west African country of Mali, a city historians cite as an intellectual and spiritual center of the 15th and 16th centuries. It's also some 3,700 miles from London. Keep that in mind when you consider a scheme to cover those miles in a car that looks like an Everglades airboat designed by Luigi Colani.

Desktop Linux – Will It Ever Stick?

About seven years ago, I tried to free myself from the oppression and misery of running Windows ME by installing Linux on my PC. Ever installed the Linux operating system? It’s not for the faint of heart. So, when it was recently reported that Linux-based netbooks are being returned at a rate four-times higher than their Windows-based brethren, I can’t say I was surprised.

How Your Laptop Will Just Keep Getting Faster

Since the invention of the transistor, silicon semiconductors have been king. But now silicon-based transistors are nearing the limit of their potential. Excess heat and manufacturing hurdles are impeding the development of ever-faster and -smaller processors. Advances in materials and chip design to resist extreme heat and move huge amounts of data, quickly, will be crucial. Experts are exploring three technologies to overcome these challenges: spintronics, graphene and memristors.
