Signal warning of radiactivity
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.

IPv6 protocol
According to the IANA (Internet Assigned Numbers Authority), the organization that assign the IP addresses, in February of 2011 all the IP addresses will be occupied. The solution to this problem is being implanted, approximately from the year 2000 and will follow implanting during a lot of years more. This consists in replace all the software and hardware that use the IPv4 protocol to another that use the IPv6 protocol. Enter into "What will happen when the IPv4 addresses will be exhausted?"

Hz is not equal to Mbps
How many times have you hear, told or wrote the expression X megs of bandwidth. I'm sure that a lot of times, because the continued use of this phrase, have been converted in the regular way of talking of all the people and is totally incorrect. Something seemed happens when say that we weight 154 pounds, being the pound a unit of mass and not of weight. We must say: "I weight 70 kiloponds" or "I weight 154 pounds-force". Follow reading if you want to know why the case of the megs of bandwidth, also is incorrect. Finish reading "The Megs of bandwidth doesn't exists"

Although I hate soccer (because of the fanaticism that generate and the astronomical amounts of money that move that we could invest at investigation), how the next Sunday it's the world championship final, I'm going to talk about soccer with robots.
The Robocup is the robot soccer competition most important of the world. The last was made in Singapore and end at the past June 25. Here you can see some videos, inform yourself about the competitions and know the last news. Finish reading "Soccer results of the Robocup 2010"
