Robot con Kinect
In one of the posts where I explained the how Kinect works, I said that wouldn't be strange that it will be use to build robots. Now are emerging the first robotic machines that someday will rebel and will begin to kill humans. Here I talk about some of them. Read the rest of "Robots, Kinect and the SLAM problem"

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

Kinect
Microsoft wants that we can play with the Xbox 360 moving us in front of the screen. For that have spend hundreds of millions of dollars in develop a device to realize the recognition and the tracking, not only of a complete person but several ones, including also 3D information, its name is Kinect. In this post you will discover how works the hardware and the artificial intelligence algorithms that uses. Read the rest of "Kinect: How works its 3D body tracking"

Kinect
The new Xbox 360 peripheral has a multiarray microphone that is capable of separate the voices that there are in front of the device from the others sounds of the enviroment to chat and use voice commands. Here you will learn how is done this difficult task. Read more of "Kinect: How works its multiarray microphone "

Processor
In this post I'm going to do predictions about how will be the hardware of the future, but not guiding me neither by the movement of the stars nor the Tarot cards, instead I'm going to base my predictions in the market evolution and some trends.
Since the years 40, the computers are being build following the John von Neumann architecture, with one processor, a memory and a controller of input/output. This will change sometime? I think so. Enter into "Four predictions about the hardware of the future"

embedded cpu
Although your car doesn't have onboard computer, probably it has more than 40 embedded processors. These are less powerful than the PC processors, but enough to perform the work that must accomplish to safeguard our security, improve the efficiency of the vehicle and reduce the pollution that generates.

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.

Ostentatious utensil of virtual reality
The virtual reality is the creation of 3D interactive worlds by computer, with the intention of immerse the user in another reality. To this, normally, is used goggles that has an screen for each eye, creating the sensation of be in a 3D world around us everywhere. See here how has evolved this discipline.

Signal warning of radiactivity
The processors aren't inmune to the radiactivity. This it produces soft errors, that are errors in the signals of its circuits, produced by the noise that generates the radiation on it. The consequences of the radiation over the machines aren't so devastating as over the human, because in the worst case we can reboot the machine, but the things that could do the machines affected by radiation to the humans, it could be dangerous.
