A carpa aprende a crescer
Fonte: http://colunas.g1.com.br/paulocoelho/
A carpa japonesa (koi) tem a capacidade natural de crescer de acordo com o tamanho do seu ambiente. Assim, num pequeno tanque, ela geralmente não passa de cinco ou sete centímetros. Mas pode atingir três vezes esse tamanho, se colocada num lago.
Da mesma maneira, as pessoas têm a tendência de crescer de acordo com o ambiente que as cerca. Só que, neste caso, não estamos falando de características físicas, mas de desenvolvimento emocional, espiritual e intelectual.
Enquanto a carpa é obrigada, para seu próprio bem, a aceitar os limites do seu mundo, nós estamos livres para estabelecer as fronteiras de nossos sonhos. Se somos um peixe maior do que o tanque em que fomos criados, ao invés de nos adaptarmos a ele, devíamos buscar o oceano – mesmo que a adaptação inicial seja desconfortável e dolorosa.

How Google Is Making Us Smarter
Our minds are under attack. At least that’s what I keep hearing these days. Thumbing away at our text messages, we are becoming illiterate. (Or is that illiter8?) Blogs make us coarse, YouTube makes us shallow. Last summer the cover of The Atlantic posed a question:“Is Google Making Us Stoopid?” Inside the magazine, author Nicholas Carr argued that the Internet is damaging our brains, robbing us of our memories and deep thoughts. “As we come to rely on computers to mediate our understanding of the world,” he wrote, “it is our own intelligence that flattens into artificial intelligence.”
I have a hard time taking these Cassandras of the Computer Age seriously. For one thing, they are much more interested in our fears than in the facts. In his new book, Txtng: The Gr8 Db8, the English linguist David Crystal demonstrates that many of the dire warnings about texting are little more than urban legends. Texting doesn’t lead to bad spelling, he finds. In fact, Crystal writes, “texting actually improves your literacy, as it gives you more practice in reading and writing.”
More significantly, the ominous warnings feed on a popular misconception of how the mind works. We tend to think of the mind as separated from the world; we imagine information trickling into our senses and reaching our isolated minds, which then turn that information into a detailed picture of reality. The Internet and iPhones seem to be crashing the gate of the mind, taking over its natural work and leaving it to wither away to a mental stump. As plausible as this picture may seem, it does a bad job of explaining a lot of recent scientific research. In fact, the mind appears to be adapted for reaching out from our heads and making the world, including our machines, an extension of itself.
This concept of the extended mind was first raised in 1998, right around the time Google was born, by two philosophers, Andy Clark, now at the University of Edinburgh, and David Chalmers, now at the Australian National University. In the journal Analysis, they published a short essay called “The Extended Mind” in which they asked a simple question: “Where does the mind stop and the rest of the world begin?” Most people might answer, “At the skull.” But Clark and Chalmers set out to convince their readers that the mind is not simply the product of the neurons in our brains, locked away behind a wall of bone. Rather, they argued that the mind is something more: a system made up of the brain plus parts of its environment.
The mind appears to be adapted for reaching out and making the world, including our machines, an extension of itself.
Clark and Chalmers asked their readers to imagine a woman named Inga. Inga hears from a friend that there’s an exhibit at the Museum of Modern Art. She decides to go see it. She thinks for a moment, recalls that the museum is on 53rd Street, and starts walking that way. She accesses her belief that MOMA is on 53rd Street from its storage place in her brain’s memory network. Now imagine a man named Otto, who has Alzheimer’s. His memory is faulty, and so he keeps with him a notebook in which he writes down important details. Like Inga, Otto hears about the museum exhibit. Since he can’t access the address in his brain, he looks it up in his notebook and then heads off in the same direction as Inga.
In the view of Clark and Chalmers, Inga’s brain-based memory and Otto’s notebook are fundamentally the same. Inga’s mind just happens to access information stored away in her brain, while Otto’s mind draws on information stored in his notebook. The notebook, in other words, is part of his extended mind. It doesn’t make any difference that Otto keeps his notebook tucked away much of the time. After all, Inga tucks the memory of MOMA’s address out of her conscious awareness most of the time too. Clark and Chalmers concluded that real people are actually more like Otto than like Inga: We all have minds that extend out into our environments.
Eleven years later, this argument continues to trigger fierce debate among philosophers, psychologists, and neuroscientists. There is no doubt that the extended mind is a weird concept. One reason it seems so strange is that our minds feel as if they are really totally self-contained. We innately believe, for example, that as we walk down a street, we are continuously filming a detailed movie of our surroundings and using that mental movie to decide what to do next. But like many beliefs we have about ourselves, this movie is an illusion. Our awareness is, in fact, remarkably narrow.
One of the most spectacular demonstrations of how oblivious we can be was carried out by psychologists Daniel Simons of the University of Illinois and Christopher Chabris at Harvard University. They asked people to watch a video of students weaving around each other and passing a basketball. Half the students wore white shirts, the other half black. The subjects had to keep track of how many times the ball was passed by members of one of the teams. In the middle of the game, a gorilla (rather, a student in a gorilla costume) sauntered through the scene. Many subjects later reported that they never saw the gorilla; their brains discarded it as extraneous.
Inside our heads, instead of making a perfect replica of the world, we focus our attention on tiny snippets, darting our eyes from point to point. We extract only the information we need for whatever task is at hand, whether we’re sorting the laundry or climbing a mountain.
We use strikingly little information in the process. Dana Ballard, a computer scientist at the University of Texas, developed a computer game to measure just how little. He showed his subjects a pattern of colored blocks in the upper left-hand corner of the computer monitor. He then had them build a similar pattern of blocks in the lower left-hand corner. To do so, the players used a mouse to grab blocks, one by one, from a collection on the right-hand side of the screen. As the players looked from the original model to the collection of blocks to their own growing pattern, Ballard tracked their eye movements. He found that players looked at the model at the upper left before they picked up a block, and then again afterward. His experiments suggest that in each glance, the players were storing only a single piece of information. The first time they noted a block’s color. The second time they noted its position in the model. Instead of keeping a detailed picture of the blocks in mind, people extracted just tiny scraps of information on a need-to-know basis.
Clark argues that Ballard’s subjects made the pattern of blocks part of their extended mind. It became a store of knowledge they could dip into, an external repository of information. It was as if Inga did not actually recall the address of MOMA but only the page in her notebook where she had written it down. Our memory holds a great deal of information. But the extended mind moves swiftly between outside and inside sources, showing little regard for where its information comes from.
Our minds do more than take in information, of course. They also make decisions and send out commands—and those commands certainly don’t stay inside the mind. In the block-building game, for example, some commands go to neurons in the hand in order to move the computer mouse. But our brains don’t make a perfect mental replica of our hands and the mouse and the table in order to calculate where the mouse needs to go. Our hands and eyes constantly send signals to the brain, and that feedback alters the signals coming back out. Hand, eye, and brain are part of the same system.
We will soon be able to enhance our brains with drugs or implants. But changes we make to the environment already alter our minds.
What’s even more remarkable about our brains is that they actually search for new things to make part of this feedback system. Imagine you are poking a stick into an animal’s burrow. As you poke away, you are aware of what the far end of the stick is touching, not the end you’re holding in your hand. This kind of extended sensation appears to be the result of a reorganization of the brain. Scientists have found that when test monkeys spent five minutes learning how to use a rake, some of the neurons in their hands began behaving in a new way. They began to fire in response to stimuli at the end of the rake, not on the monkey’s hand. Other neurons, in the brain, respond to things that appear to lie within arm’s reach. Training the monkeys to use the rakes caused these neurons to change—reacting to objects lying within rake’s reach rather than arm’s reach.
The eagerness with which the brain merges with tools has made it possible to create some stunning mind-machine interfaces. For instance, Miguel Nicolelis of Duke University and his colleagues put electrodes in the brains of monkeys to link them to a robot arm. The monkeys quickly learned how to move the arm around with pure thought; their neurons reorganized, establishing a new feedback loop between brain and robot arm.
Humans are proving just as good at this merger of mind and machine. The U.S. Navy has developed a flight suit for helicopter pilots that delivers little puffs of air on the side of the pilot’s body as his helicopter tilts in that direction. The pilot responds to the puffs by tilting away from them, and the suit passes those signals on to the helicopter’s steering controls. Pilots who train with this system can learn to fly blindfolded or to carry out complex maneuvers, such as holding the helicopter in a stationary hover. The helicopter becomes, in effect, part of the pilot’s body, linked back to his or her mind.
Results like these, Clark argues, reveal a mind that is constantly seeking to extend itself, to grab on to new tools it has never experienced before and merge with them. Some people may be horrified by how passionately people are taking to their laptops and GPS trackers. But to Clark it would be surprising if we didn’t. We are, in Clark’s words, “natural-born cyborgs.”
The extended mind theory doesn’t just change the way we think about the mind. It also changes how we judge what’s good and bad about today’s mind-altering technologies. There’s nothing unnatural about relying on the Internet—Google and all—for information. After all, we are constantly consulting the world around us like a kind of visual Wikipedia. Nor is there anything bad about our brains’ being altered by these new technologies, any more than there is something bad about a monkey’s brain changing as it learns how to play with a rake.
Neuroscientists will soon be able to offer fresh ways to enhance our brains, whether with drugs or with implants. To say that these are immoral because they defile our true selves—our isolated, distinct minds—is to ignore biology. Our minds already extend out into the environment, and the changes we make to the environment already alter our minds.
That doesn’t mean we must approve of every possible extension of the mind, and even good extensions will have some drawbacks. Socrates worried that writing would make people forgetful and unwise. Sure enough, writing did rob us of some gifts, such as the ability to recite epic poems like The Iliad from memory. But it also created a much larger pool of knowledge from which people could draw, a pool that has continued to expand (or, dare we say, continued to extend?).
There’s no point in trying to hack apart the connections between the inside and the outside of the mind. Instead we ought to focus on managing and improving those connections. For instance, we need more powerful ways to filter the information we get online, so that we don’t get a mass case of distractibility. Some people may fear that trying to fine-tune the brain-Internet connection is an impossible task. But if we’ve learned anything since Clark and Chalmers published “The Extended Mind,” it’s not to underestimate the mind’s ability to adapt to the changing world.

Google Wave: Google Tries to Reinvent Email
Google today announced a new Internet-based communications and collaboration platform; Google Wave. While some of the details are still a bit sketchy, Google Wave looks to be an integrated communications platform that brings together email, chat, photo-sharing, and collaborative editing features. Google describes a 'wave' as "equal parts conversation and document" and the Wave team basically sees it as a replacement for email and other collaboration tools.
Reinventing Email for the 21st Century
Users will be able to create 'waves,' and add documents and collaborators to it. The system will feature concurrent rich-text editing, as well as email and IM-like messaging functions. Lars Rasmussen, one of the co-founders and lead engineers behind this project, especially stressed the real-time nature of Wave, where edits to a wave, be they new messages or edits in a document, appear immediately on the screens of all participants.
From what we have seen, Wave combines aspects of productivity tools, social networks, and micro-blogging. One of the most interesting features is that every change to a wave is captured and users can 'replay' how the specific wave developed over time. Wave will allow users to send private and public messages, and Google is heavily relying on HTML5 to make the product work well in modern browsers. We will have a more detailed look at all the features of Wave once we get access to the product itself.
Developers, Developers, Developers
Google is also making a set of APIs available to developers today. These APIs should give developers the ability to enhance Wave by building extensions for the core product, but also to embed Wave's features on other sites to make them more collaborative. One extension Google offers today, for those lucky enough to have access to Wave already, is a Twitter extension, and Google will also offer the ability to integrate OpenSocial gadgets into Wave.
Interestingly, Google is taking a very open approach with this new product. Not only will it give developers access to Wave's APIs, but the team also plans to open-source the protocols at the core of Wave, which really points at the greater ambition of the Wave team to see Wave and its protocols replace at least some of today's standard communications systems.

Interactive Digital Storytelling
CALL FOR PAPERS
*** ICIDS – Interactive Storytelling 2009 ***
2nd International Conference on
Interactive Digital Storytelling
09-11 December 2009, Guimarães, Portugal
Extended Submission Deadline: July 6th, 2009
------------------------------------------------------------
ICIDS is the premier international conference on interactive digital storytelling.
It was successfully launched in 2008, superseding the two previous European conference series, TIDSE ("Technologies for Interactive Digital Storytelling") and ICVS ("Virtual Storytelling – Using Virtual Reality Technologies for Storytelling"). While the venues of these events were traditionally bound to France and Germany, ICIDS is set to overcome also this geographical limitation. The fusion of the previous conferences was most successfully inaugurated in Erfurt, Germany, as ICIDS 2008. In a very inspiring and friendly atmosphere, over 100 international participants have enjoyed high-quality talks and worked together at creative and fruitful workshops, and there were plenty of delightful occasions that gathered the attendees for more informal exchange.
ICIDS 2009 aims at setting forth the success of this new beginning. The venue will be the Centro Cultural Vila Flor, an excellent modern conference center that extends a historical palace, at walking distance from most hotels and from the city center of the historical city of Guimarães, the birthplace of Portugal.
***SCOPE***
Interactive entertainment, including novel forms of edutainment, therapy, and serious games, promises to become an ever more important market. Interactive Digital Storytelling provides access to social and human themes through stories, and promises to foster considerably the possibilities of interactive entertainment, computer games, and other interactive digital applications. ICIDS also identifies opportunities and addresses challenges for redefining the experience of narrative through interactive simulations of computer-generated story worlds.
Interactive Storytelling thus promises a huge step forward for games, training, and learning, through the aims to enrich virtual characters with intelligent behavior, to allow collaboration of humans and machines in the creative process, and to combine narrative knowledge and user activity in interactive artifacts. In order to create novel applications, in which users play a significant role together with digital characters and other autonomous elements, new concepts for Human-Computer Interaction have to be developed. Knowledge for interface design and technology has to be garnered and integrated. Interactive Storytelling involves concepts from many aspects of Computer Science, above all from Artificial Intelligence, with topics such as narrative intelligence, automatic dialogue- and drama management, cognitive robotics and smart graphics. In order to process stories in real time, traditional storytelling needs to be formalized into computable models, by drawing from narratological studies, and by taking into account the characteristics of programming. Consequently, due to its technological complexity, it is currently hardly accessible for creators and end-users. There is a need for new authoring concepts and tools supporting the creation of dynamic story models, allowing for rich and meaningful interaction with the content. Finally, there is a need for theoretical foundations considering the integration of so far disjunctive approaches and cultures.
*** SUBMISSIONS ***
We welcome research papers, case studies and demonstrations presenting new scientific results, innovative technologies, best practice showcases, or improvements to existing techniques and approaches in the multidisciplinary research field of interactive digital storytelling and its related application areas, e.g. games, virtual/online worlds, e-learning, edutainment, and entertainment.

OJJDP Promotes Internet Safety

June is National Internet Safety Month. The purpose of this observance is to raise awareness of the dangers to which children may be exposed on the Internet and ways in which they can be protected from them.
Online safety is everyone's responsibility. Parents need to be vigilant about their children's use of the computer and cell phone. Teachers need to promote responsible Internet usage by students. Internet safety organizations need to help youth develop the decision-making skills needed to use the Web safely. Only through such coordinated efforts can we maximize the benefits of the Internet, while minimizing its dangers.
The Office of Juvenile Justice and Delinquency Prevention (OJJDP) supports a number of programs and activities designed to raise awareness about the importance of online safety and to help protect children and youth from online exploitation and victimization.

Acreditando no impossível
Postado por Paulo Coelho em 07 de junho de 2009 às 00:07 in http://colunas.g1.com.br/paulocoelho/
William Blake diz em um de seus textos: “tudo aquilo que hoje é uma realidade, antes era apenas parte de um sonho impossível”. E por causa disso temos hoje o avião, os vôos espaciais, o computador em que neste momento escrevo a coluna, etc.
Em sua famosa obra-prima “Alice através do espelho” há um diálogo entre o personagem principal e a rainha, que acabara de contar algo extraordinário.
“Não posso acreditar”, diz Alice.
“Não pode?”, a rainha repete com um ar triste. “Tente de novo: respire fundo, feche seus olhos, e acredite”.
Alice ri: “Não adianta tentar. Só tolos acham que coisas impossíveis podem acontecer”.
“Acho que o que lhe está faltando é um pouco de prática”, responde a rainha.
“Quando eu tinha sua idade, eu treinava pelo menos meia-hora por dia. Logo depois do café da manhã, fazia o possível para imaginar cinco ou seis coisas inacreditáveis que poderiam cruzar meu caminho, e hoje vejo que a maior parte das coisas que imaginei se tornaram realidade. Inclusive, eu me tornei rainha por causa disso”.
A vida nos pede constantemente: “acredite!”.
Acreditar que um milagre pode acontecer a qualquer momento é necessário para nossa alegria, mas também para nossa proteção ou para justificar a nossa existência.
No mundo de hoje, muita gente julga impossível acabar com a miséria, ter uma sociedade justa, diminuir a tensão religiosa que parece crescer a cada dia.
A maior parte das pessoas evita a luta sob os mais diversos pretextos: conformismo, maturidade, senso de ridículo, sensação de impotência. Vemos a injustiça sendo feita a nosso próximo, e ficamos calados. “Não vou me meter à toa em brigas”, é a explicação.
Isto é uma atitude covarde. Quem percorre um caminho espiritual, carrega consigo um código de honra a ser cumprido; a voz que clama contra o que está errado é sempre ouvida por Deus.

About Wolfram|Alpha
Goals
Wolfram|Alpha's long-term goal is to make all systematic knowledge immediately computable and accessible to everyone. We aim to collect and curate all objective data; implement every known model, method, and algorithm; and make it possible to compute whatever can be computed about anything. Our goal is to build on the achievements of science and other systematizations of knowledge to provide a single source that can be relied on by everyone for definitive answers to factual queries.
Wolfram|Alpha aims to bring expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. Our goal is to accept completely free-form input, and to serve as a knowledge engine that generates powerful results and presents them with maximum clarity.
Wolfram|Alpha is an ambitious, long-term intellectual endeavor that we intend will deliver increasing capabilities over the years and decades to come. With a world-class team and participation from top outside experts in countless fields, our goal is to create something that will stand as a major milestone of 21st century intellectual achievement.
Status
That it should be possible to build Wolfram|Alpha as it exists today in the first decade of the 21st century was far from obvious. And yet there is much more to come.
As of now, Wolfram|Alpha contains 10+ trillion of pieces of data, 50,000+ types of algorithms and models, and linguistic capabilities for 1000+ domains. Built with Mathematica—which is itself the result of more than 20 years of development at Wolfram Research—Wolfram|Alpha's core code base now exceeds 5 million lines of symbolic Mathematica code. Running on supercomputer-class compute clusters, Wolfram|Alpha makes extensive use of the latest generation of web and parallel computing technologies, including webMathematica and gridMathematica.
Wolfram|Alpha's knowledge base and capabilities already span a great many domains, and its underlying framework has the power and flexibility to support ready extension to essentially any domain that is based on systematic knowledge. More »
The universe of potentially computable knowledge is, however, almost endless, and in creating Wolfram|Alpha as it is today, we needed to start somewhere. Our approach so far has been to emphasize domains where computation has traditionally had a more significant role. As we have developed Wolfram|Alpha, we have in effect been systematically covering the content areas of reference libraries and handbooks. In going forward, we plan broader and deeper coverage, both of traditionally scientific, technical, economic, and otherwise quantitative knowledge, and of more everyday, popular, and cultural knowledge.
Wolfram|Alpha's ability to understand free-form input is based on algorithms that are informed by our analysis of linguistic usage in large volumes of material on the web and elsewhere. As the usage of Wolfram|Alpha grows, we will capture a whole new level of linguistic data, which will allow us to greatly enhance Wolfram|Alpha's linguistic capabilities.
Today's Wolfram|Alpha is just the beginning. We have ambitious plans, for data, for computation, for linguistics, for presentation, and more. As we go forward, we'll be discussing what we're doing on the Wolfram|Alpha Blog, and we encourage suggestions and participation, especially through the Wolfram|Alpha Community.
Future
Wolfram|Alpha, as it exists today, is just the beginning. We have both short- and long-term plans to dramatically expand all aspects of Wolfram|Alpha, broadening and deepening our data, our computation, our linguistics, our presentation, and more.
Wolfram|Alpha is built on solid foundations. And as we go forward, we see more and more that can be made computable using the basic paradigms of Wolfram|Alpha—and a faster and faster path for development as we leverage the broad capabilities already in place.
Wolfram|Alpha was made possible in part by the achievements of Mathematica and A New Kind of Science (NKS). In their different ways, both of these point to far-reaching future opportunities for Wolfram|Alpha—whether a radically new kind of programming or the systematic automation of invention and discovery.
Wolfram|Alpha is being introduced first in the form of the wolframalpha.com website. But Wolfram|Alpha is really a technology and a platform that can be used and presented in many different ways. Among short-term plans are developer APIs, professional and corporate versions, custom versions for internal data, connections with other forms of content, and deployment on emerging mobile and other platforms.
History & Background
The quest to make knowledge computable has a long and distinguished history. Indeed, when computers were first imagined, it was almost taken for granted that they would eventually have the kinds of question-answering capabilities that we now begin to see in Wolfram|Alpha. See timeline »
What has now made Wolfram|Alpha possible today is a somewhat unique set of circumstances—and the singular vision of Stephen Wolfram.
For the first time in history, we have computers that are powerful enough to support the capabilities of Wolfram|Alpha, and we have the web as a broad-based means of delivery. But this technology alone was not enough to make Wolfram|Alpha possible.
