While a lot of Linux companies are closing one after the other and a lot of people are starting to wondering if GPL software can actually bring some money in, Hewlett Packard gave Linux a big boost yesterday as they announced they would use the operating system to power everything from cell phones to stereos. HP said it would develop new security software for Linux, as well as HP Chai-LX, a program to develop Linux applications for small consumer devices like stereos and cell phones. This may very well be the fruit of the work of one of the most important people in Linux history, Bruce Perens, who was recently hired by HP.
