typewriter
Because of the close of the last factory of typewriter (Godrej and Boyce), I'm going to talk about the distribution of the keys on a computer keyboard, because they have inhereted the distribution of its keys.

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

CAPTCHA
The web pages increasingly receive more SPAM of programs that automatically fill the forms of the webs. To avoid it, appears the annoying CAPTCHA ("Completely Automated Public Turing test to tell Computers and Humans Apart"). A CAPTCHA consist in a test that has to pass the person that is filling the form, to demonstrate that is a human. But, are there any test that can surpass a human and not a machine?

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. Fill your mind with "The myth of the antiradiation cactus"
