online games


Online games, are games where multiple people are involved, all at the same time from different computers. Thus transformed into a virtual battle between the competitors, in real time over a network, as we shall see later. Most online games are about war and commands between the characters that the participants choose. Similarly, there are other games online, they are less violent, but these do no attract large audiences. Now , you can play with or without the internet online games. Because if there is no connection, well, you can play in a local area network, with the number of connections required. Therefore, only the required equipment or hardware and that the same system, is networked. Furthermore, we have online games, which are perform trough the internet. These last games are the most used, since they can competed with anyone that connects to the server. So if a people is connected in the united states and china in the same game server, well, these two individuals and many others may share the same level. Today, many of the most popular online games that are purchased must carry a key for the Internet. However, this only gives a limited time to enter a network and play with other contenders. After that, you must pay each time you want to play online. Obviously, this situation changes, if you want to play in a local area network. There are game rooms with lots of computers connected to the line items for mass, and in these cases, you pay only for the time you want to play. However, as mentioned above, what most excites the fans of online fames is playing online with strangers from other countries.

First person who saw the online games

During the 1990s, online games started to move from a wide variety of LAN protocols and onto the Internet using the TCP/IP protocol. Doom popularized the concept of deathmatch, where multiple players battle each other head-to-head, as a new form of online game. Since Doom, many first-person shooter games contain online components to allow deathmatch or arena style play.

History of online games

The first commercial video game that came out was the famous Pong, which appeared in the 80s in a recreation room in California. From Pong, video games have undergone a continuous evolution to get to the sophisticated machines close to virtual reality that we see now in many recreational rooms.

The possibility of using a computer to play on networks started around 1979 when a group of students from the University of Essex created a computer version of a multiplayer role-playing game called Dungeons and Dragons, based on the use of alphanumeric text. Thus, emerged a new kind of games known as MUDs (Multi-User Dungeons or Domains) that will run quickly through the little-known Internet, and emerging the first virtual communities.
However, the real revolution of online games came in 1993 with the creation of the World Wide Web. Users had the option of free access to reduced versions of computer games for promotional purposes mainly, as is the case with the first delivery of Doom. Moreover, the rapid spread of the Internet as a medium of entertainment provided improved technologies for the networking of users and their approach to society.

It is also important to highlight the rise of the game that since the early 90s, are entertaining both children and adults.

Conclusion

In my opinion, the online games are a breakthrough because it allows people to play with people who do not know.
In addition, I think it is a form of entertainment that can help learn, and give a lot of money.
The downside that I see online games is that in some cases, violent games can create more violence, and that is not good when you play with other people.
But in general the online game, do not have to be bad.

My trip to italy




my trip to italy -


This trip to Italy we did was very special because it was the last that we will do together, because the next year each will go his way, and will finish school "Escuela 2". So this trip has been so important, especially for those who carry our whole life in this school.
In addition it has also been very special because it was a different trip, the deal with the teachers was more special, was not as if they were our teachers of biology, and Castilian, was treated as an adult friend, also placed them much confidence in us.
So I guess as other people, we have enjoyed, and we cease among us and with teachers.

The location that we went to Italy:
is a country located on the Italian Peninsula in Southern Europe and on the two largest islands in the Mediterranean Sea, Sicily and Sardinia. Italy shares its northern, Alpine boundary with France, Switzerland, Austria and Slovenia. The independent states of San Marino and the Vatican City are enclaves within the Italian Peninsula, and Campione d'Italia is an Italian exclave in Switzerland.
Italy has been the home of many European cultures, such as the Etruscans and the Romans, and later was the birthplace of the university and of the Renaissance, that began in Tuscany and spread all over Europe. Italy's capital, Rome, was for centuries the center of Western civilization. Italy possessed a colonial empire from the second half of the nineteenth century to the mid-twentieth century. Today, Italy is a democratic republic and a developed country with the eighth-highest quality-of-life index rating in the world.
The itinerary of the trip was:
The first day of the trip we left, we were all day in Barcelona, until 4 am to embark on the boat, the way to Italy.
All day until 5 am the other day we were in the boat, lying on the deck sunbathing.
At 5 am the following day off at a port near Rome, and went to the hotel room we had booked, had breakfast there, and without a shower or anything until we see the Vatican and Rome.
At night, we were in Rome to 11, and boarded the bus again to go to Venice.
In the morning we arrived on the seven near Venice and we stopped to breakfast, we were all day in Venice and 5 pm, we took the bus route Florence.
When we finally get to sleep in a bed and a shower after several days without doing so.
In Florence we went to a nightclub, and return at 4 in the morning we went to bed because we were very tired.
The next day, we visited Florence, but in poor condition because they did not stop raining, then returned to the hotel, we went t to another nightclub in the city.
The next day we went to Pisa, to make pictures with the tower of Pisa, and spend the day.
After we took the bus again to Rome to board and go home.
About 8 pm we took the boat journey to Barcelona, and disembarked at the port of Barcelona, at 9pm on the way here from Italy, gave us time to have an incident with a group of Italians.
After dinner at a self-service and spent about an hour talking with rafa and ana on the trip, and we sang a very emotional song.
During this trip, the only menu that there is: Pasta, chicken and French fries.
But despite that, I was busy traveling, the trip was more special, our stay at "Escuela 2”.

William Ockham




William Ockham -

William Ockham was a Franciscan friar and English philosopher who helped mankind, with their works and thoughts.
Made a major contribution to science and modern intellectual culture is the principle of parsimony in explaining and building theories, which became known as Ockham knife, the knife of Ockham was based on the following: the reference to a kind of reasoning based on a simple premise: equal the simplest solution is probably correct.
Following the knife Ockham, the reason was a necessary foundation for people's lives, it was as if marking a law.
Their thoughts:
Occam's position taken on the topic of the relationship between reason and faith and not involve the distinction between them and the granting to each of a particular application, such as Saint Thomas had argued, but its radical distinction and independence. The reason is no longer in the service of faith and the faith needed to clarify the reason of its own dictates. Faith depends strictly on disclosure, the reason has nothing to say, has nothing to add or remove anything to clarify to the divine word. The reason for its part, being a power granted by God to man, in order for this world, has nothing to take to the faith has to resort to natural and other powers exclusively with them to acquire knowledge possible life more perfect man.

My country





my country -

My country is Spain and it is located in Europe, in this country we speak Spanish, but in many regions have their own language, like Catalunya ,Euskadi, Valencia...
The climate here is very different depending on the north or south. In the north you can find in winter temperatures from -5 degrees , and in the south temperatures between 10 and 20 degrees.
In winter you can enjoy the sport of skiing through the high mountains in the north.
The climate in summer is high, usually in the whole territory , between 20 and 40 degrees, except for some places where you can be more or less well. In summer you can enjoy in the Mediterranean beaches coast and enjoy the summer holidays.
The currency here is the Euro, the currency is not only in Spain, it’s for all Europe. Before it reached the Euro in 2000, was the peseta, which was a coin that came with the Franco regime, which is something that we will then explain the policy now
Policy:
Now Spain is a democratic country with monarchy, this happened after Franco, when he died, and now our representative of the country is the king.
Now governs the PSOE, a political party of the left-center, but there are still political parties that follow the Franco regime, now very weak, and other parties seeking the republic.
The typical food here depends on the region , but in the community where I live, the most popular is the paella.

In summary:

- "It's a country that is not bad, but still lacks many things to change, especially in politics that I think is wrong, so I do not like the friends around this country, and I think things will change in future”.

Technology and Education



The technology and education, is the new teachings of the future, applying the criteris of now education , the benefits of the future.

The technology and education, are already visible in many schools, places around the world. This breakthrough has been changed things, that no longer need to wait for a future, I will now an example of a school in the modernization process:
-Last week came the news that a school in northern U.S. will begin the course, with other materials, will replace the standard slate blackboards interactive, instead of books bought portable paratodos children, the book each subject is on your computer using a program progressed, the tests will be conducted on computers, and at the end examinations will be sent to the professor.

These are some of the progress already can be seen in many schools around the world, but this is more, is trying to technology and education and that any change is made in a way much more comfortable and more easy to make classes, without needing to spend money on books, computers sinplemente having books. Many think that technology will end up being in classes like this school, but you can still do the same kinds of changes:
- Another exchange rate would change the agendas of paper, for other agenda such as a mobile phone. All this is the future.

And I will finish a sentence I've seen online:
-The technology and education is the future, but why we must wait until the future arrives?, If this is possible.

Web.2



Web 2.0 is a term describing changing trends in the use of World Wide Web technology and web design that aim to enhance creativity, information sharing, and collaboration among users. These concepts have led to the development and evolution of web-based communities and hosted services, such as social-networking sites, video sharing sites, wikis, blogs, and folksonomies. The term became notable after the first O'Reilly Media Web 2.0 conference in 2004. Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but to changes in the ways software developers and end-users utilize the Web.

Definition
Web 2.0 has numerous definitions. Basically, the term encapsulates the idea of the proliferation of interconnectivity and social interactions on the Web.

Characteristics
Web 2.0 web site that allows users to upload and share photosWeb 2.0 websites allow users to do more than just retrieve information. They can build on the interactive facilities of "Web 1.0" to provide "Network as platform" computing, allowing users to run software-applications entirely through a browser. Users can own the data on a Web 2.0 site and exercise control over that data. These sites may have an "Architecture of participation" that encourages users to add value to the application as they use it. This stands in contrast to very old traditional websites, the sort which limited visitors to viewing and whose content only the site's owner could modify. Web 2.0 sites often feature a rich, user-friendly interface based on Ajax,openlaszlo, Flex or similar rich media.



the Web 2.0 can be compared with the Web 1.0:
web 1 ............................................................. web 2
doubleclick............................................. google
Adsenseofoto............................................................ Flickr

stephen king







My favorite writer is stephen king, is an American author, screenwriter, musician, columnist, actor, film producer and director.
His book is fiction mixted with terror. The terror of Stephen king is different unlike any other author, because his terror isn’t simple bloody, also a kind of terror dark and sinistre.
I like Stephen King because they create a kind of emotions very intrigue and dark at the same time.
I discovered a Stephen King last year, when I read the first book was titled Christine.
Stephen was in the 2006 the best writer in the EEUU, and he wins a prize in your country.
I recommend a Stephen king books anyone that likes terror histories, but also recommened anyone that like a point of intrigue and fiction.
Now I'm going to put a sipnosis of a tour book:
CHRISTINE
The dark protagonist of this novel is a car brand Plymouth in 1958 called Christine, a survivor of a time when gasoline was cheap and rock and roll marked the rhythm of the time. Arnie Cunningham is ready to succeed at any price. And he succeeds. But while working in the arduous task of restoration, the car is showing signs of a terrible life of its own. Or is it just imagination? Dennis continues believed well, but people are dying in the dark streets and avenues of Libertyville. And there comes a time when Dennis can no longer deny the terrifying truth: Christine is alive ...

Large Hadron Collider


The Large Hadron Collider is an experiment cientifc, made by the CERN, tour location is ginebra (suiza).
This experiment must demostrate teories of some cientist, as stephen hopkins teories.
The experiment will be put into operation in stembre, after that scientists think a risk of this experiment,
the risk:
Concerns have been raised regarding the safety of the Large Hadron Collider (LHC) on the grounds that high-energy particle collisions performed in the LHC might produce dangerous phenomena, including micro black holes, strangelets, vacuum bubbles and magnetic monopoles.
its cost is very high, because the experiment requires very advanced materials and high security.
This experiment is very risky, but if the experiment goes well will be the biggest breakthrough of the 21 century.
I want to be put into operation the Large Hadron Collider.

roncesvalles




a week ago we went to the Pirinnes travel end of cours, what we spent very well was great fun and it was a camping trip to remember, is not true that we went to town, but to be in one place (with the teachers who went) and everything has come together quite so isolated in the class.
We conducted many activities such as raffting or make a piece of "camino de Santiago", raffting I liked a lot more that the "camino de santiago" as the raffting generates excitement and adrenalin downloads down the river, while the camino de Santiago was more boring because it was just walk, but we saw some very beautiful landscapes.
We also visited cities like Jaca, a very beautiful city and with many details of the Middle Ages, and later also visited pamplona, that this is closer to a city and well as a city.
We saw "el monasterio de piedra" which was an exotic place with waterfalls the rivers and vegetation, and also saw some lakes in Catalunya also very exotic.
we saw snow in May which is not everywhere you can see.
And the last day teachers we sought a place to celebrate the party.
And the day of return go to relax Caldea where we went to was the star of the trip.
In short: a journey with many hours of bus but impressionant..

Introduction of the film:
this is england it tries about one gang of skin heads, that they are united with one kid (shaun).
Shaun begins to go with the gang, but, when combo (man with nazi ideologies) returns, the gang it separated and the members of gang have many conflictsof gang have many conflicts.
My opinion about film: This film has caused me great interest and has informed me a lot about the different ideologies and fashions that can be carried by different ideologies, I think that thanks to this movie, it suggests to people who think you have Nazi ideologies, and see that not only must be said that one but also feel it is Nazi, but after this movie not many people will again say that it is Nazi, because it shows scenes very hard. I think that people should not follow a fashion that this parallel to an ideology, let alone if you do not know very well that deals with this ideology, because people associate with persons Nazi skin (such as the movie), and I I believe that everyone skin must be Nazis.
