Laptops vs. Learning
This article provides an interesting insight on the use of personal laptops in the classroom. I agree completely with the author of the article, who believes that laptops make students more engaged in the classes, althought the level of distraction when using them is massive. He makes an interesting point when he says that handwriting makes us focus more on the lesson as it is slower and gives us time to think. Despite all this, I still think that the advantagdes of handing essays and projetcs in which have been word-processed are many, and that the correct path to follow would be allowing the use of laptops in the classrooms.

Biometrics: Unlocking Doors With Your Eyes
How will we open our houses in the following decades? Will keys become part of the past or will they still be a bothersome item?. Biometrics is a science that scientists work on regularly, so that people have increased safety and comfort. This article talks about how we'll be opening doors with our eyes, probably in the next 10 or 20 years.
Hacking
What we can see in this video is that even though one has the newest hardware and software, we are still prone to being hacked. In this video, the hacker is entering the other computer by just sending an email (the other has to open it). Also, while the hacker is setting up new usernames and gaining full control of the computer, the 'host' thinks it is just a Windows Office malfunction, and doesn´t realize that he is being hacked. This is dangerous, as shown by the video, because now the hacker will know every password the 'host' types, and therefore being able to gain access to email accounts, bank accounts, etc.
Why choose biometrics?
This video makes some interesting issues arise with respect to the advantadges of biometrics over passwords. Firstly, biometrics allow for fast access, without the need of remembering a password or typing it in each time. Secondly, Biometrics are much more secure as one controls precisely who enters the system. Lastly, and related to the previous point, Biometrics allows the user to keep a record of who entered the system, which you can't do with a password. Overall, it is certainly the way to go.

Music on memory cards
It would be great if this project takes place as it is just a natural step further from CD's. Firstly, the reduced size would mean less clutter in one's house. Secondly, it would be much easier to read music files from them, especially when one has to transfer them to one's computer, which nowadays most of us do.
