In the computer science, sometimes, appears false beliefs due to the ignorance of that really occurs in the machine. This time I'm going to demystify some of this old beliefs, which say that the hard disk can't be fragmented when we run a Linux based operating system.

Although your car doesn't have onboard computer, probably it has more than 40 embedded processors. These are less powerful than the PC processors, but enough to perform the work that must accomplish to safeguard our security, improve the efficiency of the vehicle and reduce the pollution that generates.

There are a lot of people that kindly shares their connection with the neighbours, but there are a lot of more that do it without knowing it. In both cases this supposes a security risk. Don't miss the rest of "How to stop WiFi hackers?"

In this post I'm going to explain a way of waste the RAM memory instaled in the computer, which affects to a lot of users.
Since some years ago, are being sold computers with 4 or more GB of RAM, but if we use an operating system of 32 bits, it will indicate us that we are using a little less of those 4 GB. Why occurs this? Deep in "RAM memory: Why if I have 4GB or more the OS detect less?"

We can classify the ways that hard disk can breakdown in two: software and hardware. With the first I'm talking about the lost of data due to virus or accidental erasure. In these cases, if it's possible retrieve the information, it is often so cheap because only we have to use the appropriate software. Instead, the errors of hardware or physics are very expensive of repair, because are needed tools and specialized installations and only if the information that contains is enough valuable, can worth pay for it.

The processors aren't inmune to the radiactivity. This it produces soft errors, that are errors in the signals of its circuits, produced by the noise that generates the radiation on it. The consequences of the radiation over the machines aren't so devastating as over the human, because in the worst case we can reboot the machine, but the things that could do the machines affected by radiation to the humans, it could be dangerous.
