Today I'm going to dedicate the post to explain some basic concepts about the files that the 99% of the people that use a computer don't understand it very well.
Some users know that the last letters that there are at the end of a file (the extension), identifies the type of file, so, for instance, an archive ended in .JPG is a type of file of image and another ended in .GIF is a different image format with other characteristics. This, is true for most cases, but causes confusion in the cases where the extension isn't of a concrete format, unless of a format container. Don't left of read the rest of "Differences between extension and format in a file"

Tsunami picture of Hokusai
The tsunamis or seaquakes can be generated by earthquakes, submarine landslides, volcanic eruptions and giant meteors. All this variety of phenomena can be simulated in a computer to take preventive measures. Read the rest of "Tsunami simulation"

WiFi logo with bones behind
Neither me nor anyone knows if the radiations of WiFi networks and mobiles are bad to the health. There are an infinity of scientific studies about the effects of the electromagnetic non-ionizing radiations in the health, the fifty percent says that there are not evidences that prove that exists adverse effects, and the other fifty percent assert that there are. Enter into "Are WiFi Networks healthy? (II)"

The travelling salesman is a problem computationally expensive to calculate. Its complexity is exponential and, therefore, is in the category of the problems that can't be solved in a polynomial time, in other words, it's as say that an actual computer can take a lot of millennia in get the solution to the problem. If we can get the result in less time will be useful to salesmen, transport agencies, postmen, distributors, infinity of fabrication process, DNA analysis and a lot of more situations.

Internet allows that any computer cans communicate with any other computer independently of the distance. This is not magic but is thanks to large cables buried in the seabed that ply the seas and oceans around the world. ¿Do you want know the technology of these cables?
