Monitor with giant cactus
Formerly, when still the CRT (Cathodic Ray Tube) monitors were in use, emerge the myth of cactus that absorb the monitor radiations. This swindle probably was thought by some illuminated herbalist that saw the bulky filters antiradiaton that was putting in front of the screen. Surely though that he can win a lot of money selling cactus as substitute of this filters, because a cactus is a lot of more nice and friendly than an authentic filter antiradiation. Follow reading if you want to know why this belief is absurd. Don't miss the rest of "The myth of the antiradiation cactus"

HD break apart
A lot of people have only one partition in the hard disk where is the operating system, the virtual memory paging file and their personal files, because is as usually comes a computer newly purchased with Windows. Often I surprise discover the quantity of technical and people, that say be expert without having basics knowledges of the topic, that recommend have only one partition because, according to them, the hard disk works faster, when really is the opposite. Do you want to know why? Don't stop reading the rest of "Partitions of the hard disk. Are good or bad?"

linked data - semantic web
Tim Berners Lee, inventor of the Web, from the beginning wanted that his invention was semantic forming a global data base of the human knowledge, in which the information could be consulted by all the world and understood by the machines, to generate new knowledge, answer questions and create artificial intelligences that could surpass the Turing Test. This idea begins to become true, but first have to overcome several difficulties that I'm going to expose next. Read more of "The problems of the semantic Web"

grave with a computer
The past month died three great geniuses that had made that the computing be as it is today. I'm referring to John MacCarthy, Dennis Ritchie and Steve Jobs. Probably you only know who is the last, which is the only one that has had media coverage. However is the less important, because if the other two had not existed, Steve Jobs perhaps wouldn't have achieved anything. Follow reading "Great personalities of the computing deceased recently"
