optical fiber
The Christmas arrived, the streets are full of led diodes of high luminescence, the house of Christmas trees of optical fiber, the computers of USB ornaments and Santa Claus brings robots and computers to the children. A lot of technology to celebrate the born of Isaac Newton as must be. In this post I'm going to talk about how works the Christmas trees of optical fiber.

Binary code
There is a big lack of knowledge about how is measured the quantity of information in a computer. It is a fact that storage device sellers and Internet providers have take advantage to cheat us. Also, not a lot of time ago was changed the nomenclature of the international system of information units generating even more confusion.

Alan Turing
The same as others disciplines as mathematics, the informatics don't have Nobel prize. So a equivalent award, had to be invented in computer science, called Turing prize, in honor to Alan Turing, that did important contributions to the computer science in the beginning of it.

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.

de-fragmentation
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.

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.
