Studying English in Spain A long time ago I studied English at the high school. I had lessons several hours per week for four years. The odd thing about this is that I did not learn anything useful. This is because the lessons were only about grammar rules. To pass the exam you only have to apply rules to a set of words. It was a pity that I studied so much time English and when I had to have a trivial conversation with an English spoken person I could not understand anything! I thought today the teachers are better in my country and they also teach you to communicate. I also think that the possibilities to use Internet to listen English or even speak it, for example, with Italki is great, and makes it possible to improve English better than before.

Can a machine think like a human? In the field of computer science, Artificial Intelligence is a discipline that is being very popular in the last years. Artificial Intelligence goal is that computers can do things that now only humans can do. Computers are good making calculations that are well defined by a programmer and all data are well known. On the other hand, humans are good solving problems when there is fuzzy data. In order to solve this kind of problem with computers two approaches can be taking: 1. Using statistics, that is to say, the fuzzy data is used to calculate probability distributions. 2. Coping the human brain, that is to say, using artificial neurons and connecting them together to build an artificial brain.

The end of the work The man productivity increases each year. If the man productivity increases, then, fewer men are necessary to have the same amount of products. Therefore, we could think that these workers have to earn more money. But, this is wrong. Over the last years, the wages are decreasing because of the supply/demand law applied to the workforce. What I mean to say is, if a few workers produce all the goods, then, there is more supply of workers than demand, indeed, the price goes down. A long time ago, when the system had this problem the state adjusted the wages with a law that decreases working hours per day. Today this problem is bigger and some heterodox economists have proposed a basic income that allows welfare to all the people. On the other hand, other economists say that this idea is a utopia and there is not enough money to pay it.

My job as a salesperson I am trying to do a company with a friend of mine. We are both software engineers and we know more about computers than about people. The most difficult about selling software is to explain people who kind of problems they can solve with our programs. This is because ordinary people do not understand computers. Things that are very difficult with computers they think that are easier and things easier they think that they are harder.

My first notebook entry This is my first Notebook entry. I want to give thanks to the Italki people to do a web page so great. I think that it is possible to learn a lot with this method. The more important to learn a language is: 1. Listening a lot. 2. Speaking a lot. 3. Reading a lot. 4. Writing a lot ... Practice, practice, and practice.
