RAM memory
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? Follow discovering "RAM memory: Why if I have 4GB or more the OS detect less?"

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"

Inside of a hard disk
Often the people lost the data of their hard disk due to don't know some of the more common things that they mustn't do with them. Do you want to know how much lifetime has a hard disk?, How enlarge its life? or how you can break it accidentally? Finish reading "Prolongs the lifetime of your hard disk drive"

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.

Kempelen machine reconstruction
Over two hundred years ago, in 1779, Christian Kartzenstein did 5 whistles that made blew the vowels artificially. Few years after, in 1791, Wolfgang von Kemplelen presented his "Acoustic-Mechanical Speech Machine" that we could consider the first voice synthesizer because it could produce isolated sounds and some sound combinations. Read all about of "The first voice synthesizer"

The voice synthesizers are those programs as Loquendo, which provide of human voice to the machine. Although the majority of them have a voice very robotic, without intonation and feelings, but we can understand it. Here you see roughly how is imitated the human voice in a computer and because is so difficult achieve a voice equal to the human one. Follow reading "How works the voice synthesizers?"
