Perform OCR with Google Docs – Turn Images Into Editable Documents

Fonte: http://www.labnol.org/internet/perform-ocr-with-google-docs/10059/

Google Docs can now perform OCR on digital images. You can upload an image containing typewritten or printed text (like a fax document or a scanned newspaper clipping) to your Google Docs account and it will turn that image into editable text.

In the following example, Google Docs successfully extracted all the text from a scanned book page and converted it into an editable document.

google docs ocr

The OCR feature in Google Docs is not part of the standard UI yet but you can use thissample form to upload scanned images to your Google Account and the server will automatically try to extract text from these images provided the image resolution is good and that the text inside images is written using Latin character sets.

The OCR feature can also extract text from noisy images as well (like this WSJ clipping) though the recognized text is not very accurate and the document formatting is lost (seeconversion results).

If you are a developer, you can add the ocr=true parameter to your upload request and Google Docs will automatically scan that image for text patterns. You can also upload images to Google Docs without the OCR parameter but in that case, the image will be converted into a new Word document sans OCR.

Like Google Docs, Google Search too includes OCR features but the difference is that while Google Docs can extract text from images, the OCR in Google Search works only withscanned PDF files.

Independent Thinking

Fonte: http://www.web2media.net/laktek/2009/08/08/independent-thinking/

Independent thinking and self-concious decision making is what builds a person and the society. Yet, it’s the most discouraged, criticised and often punishable act that a person can do. Our culture has done a nice job by misinterpreting and abusing values - such as obedience, loyalty and teamwork to suppress the importance of independent thinking.

This starts to happen from our birth, where parents tries to give extra protection and care all the time. They will not let their eyes off the child, would not allow the child to touch anything or to play at his desire. This may be purely unintentional and due to their excess love for their child. However, unconsciously when they continue this beyond the limits, they do actually harm their child by blocking the creative sense and opportunities for self-realization. Afterall, humans are not weak as we seem.

As I discussed in the previous post, schools to exert enough pressure to kill off the rest of the independent thinking capabilities within a person. This will continue to happen until the exam oriented education structure vanishes and people realises the value of each other irrespective of the educational or social background he comes from. Sir.Ken Robinson nicely presents this point in this TEDTalk. Take some time to watch it, if you haven’t seen it before.

Things get worse, when you enter into higher education, where you expect the independent and critical thinking is to be fostered. You are guaranteed to have poor grades if you are to challenge or tries to explore beyond what is taught. Parrotised lecture notes should be vomited on the paper if you want higher grades (is it the lack of knowledge or envy is still a puzzle). With the beliefs of higher the GPA, higher is your salary, nobody doesn’t seem to be bothered to diss the current knowledge system. These professionals are so vulnerable to change and would never encourage their sub-ordinates to change. This results with a legacy knowledge system that is incapable of solving today’s problems.

When it comes to politics, corporate business or any other form of community activities you see the obvious. There is very little room (or actually no room) for independent thinkers. You’re assured to be sidelined, mocked, harassed and in worst case even to pay the penalty with your life, if you are to hold a different point of view from the so called majority (which is actually a minority, which has exploited the power and force to grab the blind following of the rest, who have been trained not to use their wit by the earlier systems).

Just think about it independently ;)

It’s very sad and alarming to hear the recent incidents taking place at Sri Lankan schools. Government shows they are so concerned about these issues by banning everything they believe that can harm our next generation :) Mobile phones at all schools are banned, Web Sites with explicit content are banned, screening of “Adults only” movies are banned. Ok, now government could say they have taken all necessary steps to groom our next generation to be well disciplined citizens, and future our country is guaranteed to be prosperous.

However, governments and its so-called advisers will never realize the root causes of all these problems. Their short sighted decisions and floating policies from the past, have aggravated these problems to this level and none of their decisions would help to change the situation in the long run.

I believe Sri Lankan education system is screwed in big time! Kids are thrown in to a rat race from the kingdergarden, when they don’t even have a slight clue on where they are heading. Not to mention, even after going through all the steps of primary, secondary and tertiary education, more than 80% of them still don’t have an idea why they ran all these years. It leaves a big question whether do we have to run at all?

Aside from the spoon-fed knowledge only selfishness, insensitivity, jealousy and hunchback (after carrying a school bag of 4KGs) are the only gains of this current education system. Why Sri Lankan education system failed so miserably in building citizens with self-confidence that they are someone who is adding value to the society? Why can’t someone be a janitor, carpenter, factory worker, farmer, dancer, sportsman or a doctor and still feel they are all equal in the society?

This false social grading starts from the primary school admissions. It’s only the kids of the rich and so called elites will be admitted to the popular schools. No matter how closer you live to the school, your child would not be admitted if you cannot afford to give a hefty donations to school’s development fund or if you don’t have enough civil power and political influence. From year 1 these kids starts associating only with a certain social layer and will never understand their is another way of life lower or higher than them. They will measure the quality of their lives relative to these layers. Basically, layer above them are the most superior, powerful and layer below them are the inferior, wretched. They will never understand all these social layers has their own mix of good and bad.

Next biggest mistake is the mis-interpretation of aesthetics and extra-curricular activities in schools. You are not allowed to sing or a dance, if you are cannot select for Derana Little Star. If you are not a play cricket, if you cannot select for college XI. Talking about myself, I had no skill on any sport or aesthetics. Still, I went to football practices, bloody well knowing that I will never be selected for the college team. I participated in drama, dancing and singing practices for cultural day in every year, though I only got the chance to be on stage handful of times. Later I learnt it wasn’t my talent. But looking back today, the experience and lessons learnt through those activities is impossible to gain from sitting in a classroom. The negligence of extra curricular activities in schools is also a main cause of the unfortunate incidents we hear today. I know some schools cancelling Sports Meets, Cultural Days to finish the syllabuses on time. Can we call such places as schools?

There are more stuff running through my mind, but I will stop this rant at here. What I want to stress is whether you are a govt. official, principal, teacher, parent, got a sibling or even a total outsider - please pay your attention to the root causes and be aware of what’s really happening at schools. I’m sure none of you would want to hear more unfortunate incidents.

Education in the Digital Age – What Does It Mean?

Education in the Digital Age – What Does It Mean?

© OEB

Is education – in a more classical sense, or “Bildung”, as the Germans say, – in danger of falling by the wayside in the digital age? Or is it possible to provide a personal learning environment that really serves a holistic, individual and lifelong learning experience? What could be done to encourage students to reflect on their own online-learning process? Frances Bell, Griff Richards and Per Skafte Hansen explore these questions from very different angles in the “Thinking About Learning” session at OEB 2009.

To rethink one’s personal attitude towards learning and how to organise it successfully is at the core of the e-learning discussion. A session at OEB 2009 dedicated to ”Thinking About Learning” will provide a thought-provoking platform to reflect on recent research and initiatives. A very practical approach in this regard will be presented by Griff Richards, Althabasca University, Canada. With his team, Richards has developed a tailor-made, online coaching module for students who are planning to enroll in online classes. What he offers is a series of short videos helping students to develop appropriate meta-learning strategies to handle e-learning effectively. The main emphasis is on networking and collaboration. Students should be given the necessary knowledge to enable them to set up their own support networks and communicate to help each other out. At the end, they are asked to reflect on the contribution of their actions to becoming successful online learners.

“Bildung” The German word “Bildung” covers a complex semantic field. A one-word translation might be “education”, but the overall concept is much broader.

The term “Bildung” dates back to sixteenth century Pietistic theology. At that time, it transmitted the belief that Christians should undertake the “cultivation” (Bildung) of their talents and shape their dispositions according to the image of God, which was seen to be innate in their souls. Most important German philosophers, including Leibniz, Herder, and Hegel, moulded their own individual interpretation of the complex idea of “Bildung”.

Per Skafte Hansen has chosen “Bildung” for his presentation at Online Educa Berlin in order to describe the synthesis and internalisation of education, experience and (sometimes almost subconscious) reflection that together form the basis of an individual’s lifelong maturity process.

Click here to watch the video.

The importance of getting connected and collaborating will also become apparent in Frances Bell’s presentation on “Connectivism – Learning for the 21st century”. This new learning paradigm, offered by Stephen Downes and George Siemens, describes the learner not as an isolated individual but one who is connected. Connectivism means that learners are not only part of a network of individuals but they are also connected to knowledge itself. Given the fact that the network is always accessible and is becoming increasingly essential, learners need a deep understanding of where to find information. Consequently, meta-learning strategies become as important as learning itself. At OEB 2009, Bell will present a new study examining connectivism as a theory in use by around 2200 people who participated in a Massive Open Online Course (MOOC), a super-size open education course.

Fundamental questions concerning the use of e-learning tools are raised by the Danish Knowledge Manager Per Skafte Hansen: What he questions is whether “Bildung” in a more classical sense can still be delivered in a digital world with its pressure for more and faster factual learning. Hansen, however, not only wants to position himself as a media critic; he also seeks to depict his ideas of future-oriented solutions to integrate e-learning tools optimally in a lifelong learning scenario.

What comes to his mind when thinking about a personal “Bildung” environment is some sort of an “old-fashioned” diary containing logs of significant events and a repository of personal reflections. This would help users/learners to “craft” their own “Bildung”.

Frances Bell, Griff Richards and Per Skafte Hansen will present their ideas at OEB 2009 in the session “Thinking About Learning” on Thursday, December 3, from 14:15 – 15:45.

If You Need to Work Better, Maybe Try Working Less

Fonte: http://online.wsj.com/article/SB10001424052970203803904574429151858232582.html

It was 4 p.m. on a recent Friday—a time of the week when I usually relax and leave the rest of my to-do list to finish over the weekend. But as this recent weekend approached, I kept pushing myself, heart pumping, to get to the bottom of my list of planned tasks for the week.

After years of working on and off throughout most weekends, I was trying a new approach by taking off at least one entire day every weekend this month, away from reporting, writing and all other work. Early on, I hated it. As simple as it seemed, sticking to a time-off plan stressed me out at first. What I didn't see right away was that my little test was forcing me to improve the way I work.

Amid layoffs and burgeoning workloads, it seems, working any time, all the time, has become a habit. A survey of 605 U.S. workers last spring by the Society for Human Resource Management found that 70% of employees work beyond scheduled time and on weekends; more than half blame "self-imposed pressure." Now, new research suggests some have reached the point where a paradoxical truth applies: To get more done, we need to stop working so much.

Work & Family Mailbox

Down Time

Sticking to a schedule of predictable time off can lead to improved productivity. Here are some steps to get started:

  • Agree on future goals with your boss and coworkers.
  • Plan for deadlines far in advance.
  • Set, and focus on, top hourly, daily or weekly priorities.
  • Cooperate with coworkers to back each other up.

A groundbreaking four-year study, set for publication in the October issue of Harvard Business Review, seems to confirm that getting away from work can yield unexpected on-the-job benefits. When members of 12 consulting teams at Boston Consulting Group were each required to take a block of "predictable time off" during every work week, "we had to practically force some professionals" to get away, says Leslie Perlow, the Harvard Business School leadership professor who headed the study.

But the results surprised Harvard researchers and Boston Consulting executives alike. Working together to make sure each consultant got some time off forced teams to communicate better, share more personal information and forge closer relationships. They also had to do a better job at planning ahead and streamlining work, which in some cases resulted in improved client service, based on interviews with clients. Boston Consulting is so pleased with the outcome that the firm is rolling out a similar teaming strategy over the coming year on many new U.S. and some overseas projects, says Grant Freeland, senior partner and managing director of the firm's Boston office. "We have found real value in this," he says. "It really changes how we do our work."

Other companies are putting the brakes on work in other ways. At KPMG, a professional-services firm, managers use "wellness scorecards" to track whether employees are working too much overtime or skipping vacation, a spokesman says. At Fenwick & West, a Silicon Valley law firm, "workflow coordinators" review attorneys' hours to avert overload.

And at Bobrick Washroom Equipment, North Hollywood, Calif., a 500-employee manufacturer, staffers are expected to leave in time for dinner. "If you walk around here at 5:30, there are going to be very few lights on, and that's what we expect," says Mark Louchheim, president. He sees family dinners together as important to the well-being of employees and their children, and he also believes setting limits on work motivates people to work smarter.

In the Boston Consulting study, most of the four- or five-member teams were asked to guarantee each consultant one uninterrupted evening free each week after 6 p.m., away from BlackBerrys and all contact with work. Each team held weekly meetings to talk about the time-off plans, work processes and what consultants called "tummy rumbles"—gut worries or concerns about their project.

Requiring hard-driving consultants to take time off was "nerve-racking" and awkward at first, says Debbie Lovich, a Boston Consulting executive who headed one of the teams. Some fought the idea, claiming they would have to work more on weekends or draw poor performance ratings.

But the point of the experiment wasn't to eliminate the "good intensity" in work—the "buzz" from constant learning and "being in the thick of things," Harvard's Dr. Perlow says. Instead, researchers targeted "bad intensity"—a feeling of having no time truly free from work, no control over work and no opportunity to ask questions to clarify foggy priorities, she says.

Ms. Lovich adds: "We wanted to teach people that you can tune out completely" for a while and still turn out good work. The work itself became the focus, "because if you know a night off is coming up, you're not going to let things spike out of control," she says.

After five months of predictable time off, internal surveys showed consultants were more satisfied with their jobs and work-life balance, and more likely to stay with the firm, compared with consultants who weren't part of the experiment. As word spread, other consultants began asking to join the study, Ms. Lovich says. And some clients told researchers the teams' work had improved, partly because improved communication among team members kept junior consultants better informed about the big picture.

Bobrick Washroom Equipment's policy to get workers home for dinner came as a shock to Janice Blakely when she joined the company years ago after working "long, long hours" at an energy concern, she says. Seeing staffers at Bobrick leave by 6 p.m., "I thought, 'Wow, this is not normal."' But in time, the policy "made me look at my performance and tighten up on what I'm doing," says Ms. Blakely, a marketing manager.

Mr. Louchheim, the Bobrick president, says that employees who habitually stay late may be revealing poor work habits. "We worry about whether they can delegate properly and prioritize their work," he says. Adds Chris Von Der Ahe, a Korn/Ferry International recruiter who works with Bobrick: "People who do well there are well organized and able to plan their work well."

Dr. Perlow says an individual worker can get similar results "by challenging oneself to say, 'I'm going to cut off' " work at a certain time every day or every week. " 'Now, how am I going to get work done in the time I have?' This is meant to open your eyes to the possibility" that the way you work can be changed.

In my own experiment, I have managed to keep at least one weekend day work-free so far this month. This has forced me to put proven time-management principles into practice: Plan blocks of work time and stick to the plan; set short-term deadlines to keep work from spiraling out of control; and keep up with email daily, to avoid backlogs.

The rewards have been surprising. On one recent Monday, after an invigorating weekend of working out, attending church and watching college football and hiking with friends, I quickly solved a work problem that had baffled me the previous week. Asked to assess my work this month, my editor, John Blanton, said my columns have been fine. "I'd say, from our perspective, start enjoying your weekends," he wrote in an email.

This, I hope, will get to be a habit.

We'll be immortal in 20 years, says Kurzweil

I want to live forever. I want to learn how to fly. High. I feel it coming together.

And, thankfully, so does celebrated large brain and, who knows, maybe "Kids from Fame" aficionado Ray Kurzweil.

In an article reported by the Telegraph, Kurzweil says that our technological and genetic know-how is marching at such a furious pace that in 20 years' time we should be holding in our sweaty, excitable hands the nanotechnological secrets of our existence.

This charmingly optimistic view is but another string hanging from the nano-forecasting bow he's been wearing for years, along with his rather singular vision of the way men and machines will cohabit happily ever after.

Extraordinary nanotechnological secrets should allow us, according to Kurzweil, to replace our kidneys, livers, hearts and, hey, what about minds, with functioning vital organs made by human hands.

They say Kurzweil is 61. He doesn't look a day over 43 to me.

Kurzweil's contemplations, first published in The Sun, offer us these vast nuggets of hope: "I and many other scientists now believe that in around 20 years we will have the means to reprogram our bodies' stone-age software so we can halt, then reverse, aging. Then nanotechnology will let us live for ever."

Yes, you can be 28 again. You can drink yourself stupid and let those nano-nano folks just slip you a new liver. You can have sex, drugs, and rock and roll, and still be able to perform Whitney Houston karaoke better than Whitney herself can these days.

"If we want to go into virtual-reality mode, nanobots will shut down brain signals and take us wherever we want to go," said Kurzweil. "Virtual sex will become commonplace. And in our daily lives, hologram-like figures will pop in our brain to explain what is happening."

One can only hope those hologram-like figures don't resemble the chaps from Google too closely.

And I am not entirely sure I am persuaded by the concept of virtual sex. Perhaps worse would be the concept of some Googleperson-like hologram talking one through virtual sex. And whispering to one after it.

Still, Kurzweil's passionate certainty offers us all hope for a very different future from the one we might have imagined.

I can't wait. No, really. I can't.

Microsoft to open Windows Cafe in Paris

Microsoft confirmed on Wednesday that it plans to open a "Windows Cafe" in Paris where people will be able to try out the latest from Redmond while drinking a cup of coffee.

The cafe will open on 22 October — the day that Windows 7 launches, Microsoft said.

"This initiative expresses our intention to meet with the general public and show the new Windows experiences on PC, mobile and on the internet," a Microsoft representative said in a statement to CNET News. "People will be able to discover Windows 7, the Windows phones and the Windows Live services."

Microsoft's statement comes after photos of the cafe appeared on a French technology website.

In the United States, Microsoft has announced plans to open a network of retail stores — with the first two opening later this year. More are slated to open next year.

For now, the Paris location is the only cafe planned, Microsoft said.

Others chimed in on Wednesday with some interesting tidbits. TechCrunch observes that, ahead of the opening, the cafe is already offering free Wi-Fi to those on the footpath, while Silicon Alley Insider notes that the location was previously home to an eatery called Wet Willie's.

LEVANTA-TE E ACTUA 2009

Já começou a contagem decrescente para 17 de Outubro, Dia Internacional para a Erradicação da Pobreza. O “Levanta-te e Actua” é uma iniciativa global que entre 16 e 18 de Outubro apela a todos para que se levantem, exigindo que os seus governos cumpram com as promessas de acabar com a pobreza extrema e que se alcancem os Objectivos de Desenvolvimento do Milénio (ODM) até 2015. Em 2008, mais de 116 milhões de pessoas em todo o mundo levantaram-se, quebrando o recorde mundial reconhecido pelo Guiness. Portugal contribuiu com mais de 93 mil vozes nesta iniciativa. À semelhança do ano passado, espera-se que 2008 volte a ser um grande momento de mobilização a nível nacional acreditando que, juntos, alcançaremos pelo menos os 100 mil participantes. Estão a ser programadas diversas acções de norte a sul do país, como forma simbólica de luta e protesto: concertos musicais, actividades desportivas, performances teatrais, dança, tertúlias, entre muitas outras acções. Lançamos o convite para que todas as portuguesas e portugueses actuem, participando. Diariamente morrem 50 mil pessoas de pobreza extrema. A desigualdade entre os ricos e pobres não pára de aumentar. Aproximadamente metade da população mundial vive em situação de pobreza.
Não podemos ficar indiferentes! www.levanta-te.org
Conforme vão elaborando as actividades, registem-se no site e enviem-me essa informação.

Study: Microbloggers are really boring

Fonte: http://news.cnet.com/8301-17939_109-10357359-2.html

A study from the Helsinki Institute for Information Technology has found that most microbloggers are updating their status with "mundane" messages.

Curiously, the Finnish institute chose to examine the also-ran microblogging platform Jaiku. In sifting through 400,000 messages on Jaiku, HIIT found that the most common messages users send out include the words "working," "home," "work," "lunch," and "sleeping."

"Microblogging works because of the total control users have over their postings, but it is a hobby that seems to require a significant investment of time which many cannot afford," the Institute said in a statement.

Jaiku is now a shadow of its former self, some two years after it was acquired by Google. According to the site's About page, it's "maintained by volunteer Google engineers on their spare time," after the Web giant decided at the start of the year that a half-dozen products including Jaiku, Dodgeball, and Google Video weren't contributing to its brand or bottom line. In March, the service was moved to Google's App Engine. The company also open sourced its code base, putting the future of the service "in developer hands."

As valuable as the Institute's finding might be to Jaiku users, Twitter is the dominating force in the microblogging space. The Institute didn't analyze tweets, making the study less applicable to the entire population of microblog users.

That said, earlier this year the Oxford University Press studied 1.5 million tweets to see which words were found most frequently on the popular service. Aside from obvious words like "the," "it," "and," and "to," the organization found that "work", one of the top words on Jaiku, is also a top term on Twitter. It was included in over 26,000 tweets the organization analyzed and was one of the most-used terms on the site. One of the least-used terms Oxford found in its study was "running." It was included in just 3,195 of the 1.5 million tweets it researched.

The study from the Helsinki Institute for Information Technology will be available in an upcoming issue of the Personal and Ubiquitous Computing Journal.

evolução dos computadores portateis

Desde que se tornou claro que os computadores seriam fundamentais na Sociedade da Informação que se procuraram formas de tornar a tecnologia mais compacta e mais presente em qualquer lugar. A evolução das primeiras intenções de protótipos até aos dias de hoje foi muito rápida, quer em termos conceptuais que em termos de design, e é interessante recuar alguns anos apenas para perceber o quanto a tecnologia mudou.

Foi na década de 70 que começaram a surgir as primeiras ideias relativas à portabilidade introduzidas por Alan Kay da Xerox. No entanto, o primeiro modelo efectivo foi o Osborne 1, produzido por Adam Osborne. Uma maravilha conceptual para a época que pesava cerca de 11Kg e possuía um monitor minúsculo. Repare-se na forma como o teclado podia ser encaixado no chassis, tornando o modelo extremamente "compacto" e facilmente transportável.

Entre 1981 e 1984 surgiu o Gavilan, que introduziu conceitos mais semelhantes aos portáteis de hoje. Em termos de design o teclado e a abertura do ecrã são praticamente idênticos. Foi também o primeiro a correr com baterias de Níquel-Cádmio com uma autonomia de 9 horas e uns fantásticos 4Kg de peso.

A partir daí muitos outro modelos surgiram mas o conceito estava lançado, havendo somente constrangimentos tecnológicos que impediam a miniaturização de determinados elementos. Até há muito poucos anos, as gigantescas unidade de armazenamento móvel como os discos de 5"1/4 e depois as de 3"1/2, baterias e discos duros, limitavam a redução do tamanho e peso. À medida que a indústria foi produzindo opções práticas e económicas, os modelos foram evoluindo até ao patamar de hoje. Será muito interessante aguardar mais uns 10 anos e perceber as maravilhas tecnológicas que nos esperam.
