Against Team Frednet project

Team freadnet supported by Google has the ambitious project of sending a robot to the moon, which will go 500 ft and will take some pictures. In order to do that, this project is going to be open-project, so anyone interested could participate. This project promise to be expensive, but Google is offering 20 millions to the winner that can get the job done. Is this not absurd???!!!! Send a robot to the moon just to take pictures is pointless and has no sense at all. Is not this project a waste of money and energy?? Do not get this wrong, I encourage investigation, team work and in general I am a supporter that all that has to do with science, but in this case, I completely disagree with the project. I could make a long list of all the things that would be better off with all that money, energy and talent that the participants in this project would spend. For instance they could invest on bio-engineering, find way to reduce pollution or protect the wild life that is in risk to disappeared, or what about find ways to eradicate poverty. What about bring technology to people that has no access to it, or more support on research for illness such as cancer and SIDA. As I said before, I could keep giving examples of better projects that would be really helpful to people from all countries. So if you are thinking on support this project, I will not say that you should not do it, but think it twice please.

Kernel numbers

How the kernel is numbered talk about the version of it. For instance, on February 24, 2010, Linux 2.6.33 was released. Using this last version as an example, we are going to break it down and explain its parts.(please scroll down)





















26330
Major numberMinor numberMicro numberPatch level
This number represents the kernel version and it only change when some major changes in the kernel code occur. It started with 1.0 in 1994 and has change only once in its history.This represents a major revision in the kernel. It is classified either even or odd number. If it is an even #, means stable release. If it is an odd # means that it is in development. This stands for minor revision in the kernel, such as updates or new features added.Sometimes there is a fourth number that represents some extra corrections such as security patches and bug fixes.

I could not tie this thing together, for some reasons it let a blank space in the middle, I apologize for that!
