Our Web Videos Reveal More Than We Realize, and Perhaps More Than We Want

By Jacob Ward Posted 06.29.2012 at 10:04 am

As we upload more and more videos to the Internet—one hour of new video every second to YouTube alone—experts are finding new ways to mine them. A team led by Igor Curcio of Nokia's Research Center, for example, has developed an algorithm that stitches concertgoers' cellphone footage into a single, synchronized multi-angle film. The concept is relatively simple: the audio track serves as a guide to sync up the footage, and the software chooses the best shots. Curcio has no real business model yet—photography is prohibited at most concerts—but giving people the ability to identify and coherently connect common elements in multiple videos is nonetheless a step toward something significant.

For instance, the drones that patrol the U.S.-Mexican border and the security cameras in cities already record more footage than human observers can possibly examine. If an agency could rely on a computer to track individuals, groups and events on its own, agents could use intelligence far more—well, intelligibly.

That new capability will drive the demand for even more raw data. The Intelligence Advanced Research Projects Activity (IARPA) agency, overseen by the U.S. director of national intelligence, has launched two projects that may help analysts use civilian video from YouTube, Vimeo and other sources. Investigators at the Finder program are studying ways to locate where and when a video was taken based solely on the image itself. That's hard enough. But researchers at IARPA's Aladdin are working on an even more challenging task: how to search for "specific events of interest." If they succeed, analysts could feed in a name, a simple text description or a few sample videos of what they seek—say, "five people wearing backpacks next to a pickup truck"—and get back any number of clips that match the query.

Beyond categories lies the greater hurdle of finding not just an event or a group of objects but a single object: a missing child, a misplaced purse, a suicide bomber in a... (more at http://www.popsci.com/technology/article/2012-06/our-web-videos-reveal-more-we-realize-and-perhaps-more-we-want )

Why You’re Probably Working an Extra Two Months This Year

Chris Taylor July 2, 2012 by

Looking forward to that July 4 holiday? Of course you are. But be honest: what are the chances you're going to sneak a look at your work email at some point during the day, just in case?

A new survey from mobile security firm Good Technology confirms what we already knew — that Americans' work-life balance is going from bad to worse. The stats read like a depressingly familiar roll call of what's wrong with our hectic connected existence.

Some 68% of us check work email before 8 a.m., with half of us doing so before our heads leave the pillow. (The average check-in time of the 1,000 randomly-selected respondents: 7:09 a.m.) At the other end of the day, 69% of us can't slip into slumber unless we've checked that old work email one last time.

But perhaps the most eye-popping part of the survey is how much all that extra time adds up to. Simply by answering work-related calls and emails when we've left the office, the average respondent is working an extra seven hours a week. That adds up to 365 hours...

The party that didn't go off with a Big Bang: Stephen Hawking held a party for time-travellers - but no-one turned up...

It is the ultimate test for time travellers - hold a party for them, but don't post the invites until after the event.

But sadly, when Stephen Hawking tried this, he was left to his own devices - for across all of time and space, his invite to literally anyone who ever will exist landed on deaf ears.

Professor Hawking offered this as 'experimental evidence that time travel is not possible' - although we secretly hope that by publicising the party's existence (held on June 28th 2009), someone in the future might retroactively decide to visit.

Scroll down for video:

This was Stephen Hawking's attempt to welcome time travellers - but perhaps the guests just thought it felt so 2009

A party to remember until the end of time: Stephen Hawking waited and waited, but no-one turned up...

According to Ars Technica, the Brief History of Time author explained: 'I have experimental evidence that time travel is not possible.

'I gave a party for time-travellers, but I didn't send out the invitations until after the party.

'I sat there a long time, but no one came.'


It is a sad, but quite intriguing, image: Professor Hawking in a room by himself, surrounded by canapes and champagne, and expectantly waiting for the door to open or some kind of Doctor Who-style TARDIS to appear in the room thanks to some timey-wimey loophole assistance.

In fact, you can see this poignant vignette for yourself, for the party was filmed and put on YouTube.

You're still welcome to come at any time: Your invite is here

Still, perhaps it was a good thing that no-one came.

For Hawking said that while Einstein's theories alllow for time travel into the past, but that 'it is likely that warping would trigger a bolt of radiation that would destroy the spaceship and maybe the space-time itself'.

Top 5 Things The Cloud Is Not

At http://www.wired.com/cloudline/2012/06/top-5-things-the-cloud-is-not/

Top 5 Things The Cloud Is Not

It's clear that the technology industry is moving from the PC era to the cloud era in several significant ways.  While cloud represents a new way for IT to deliver — and end users to consume — IT applications and services, this transition also represents a significant change in how applications, services and systems are defined.  The move to cloud computing is the most important technology disruption since the transition from mainframe to client-server, or even since Al Gore invented the internet. While industry veterans like Oracle's commander in chief declared it a fad, this is a decade-long trend that is here to stay, and one that will define the next generation of IT.

The movement itself has been in play for the last decade, however there continues to be a lot of (mis)information in the marketplace about the cloud. So much so that it is difficult for organizations to figure out what is real and what is not to help them develop a successful cloud strategy, or simply learn about technologies  that have been specifically designed and purpose-built to meet  this dramatic shift in technology. While it's important to know what the cloud is, it's just as important to separate the wheat from the chaff, and for IT to understand what cloud is not.

To this end, I encourage you not to add yet another definition of the cloud to your glossary, but to truly understand the top 5 things the cloud is not.

1. Cloud is not a place. People often talk about moving to the cloud as if they were moving to another city. But the cloud is not a place. In fact, the cloud can be anywhere, in your data center or someone else's. Organizations that believe they are moving to a strategy that leaves legacy apps and systems behind are in for a rude awakening. The single most important way for enterprise organizations to prepare themselves for the cloud is to understand that the cloud is a radically new way of delivering, consuming and adopting IT services in a far more agile, efficient, and cost-effective manner, which will spread throughout the ether and be a mix of public, private, managed or hybrid clouds. By looking holistically at the cloud, organizations can optimize its benefits for their budgets, privacy needs, geographies and overall business needs.

2. Cloud is not server virtualization. Despite what many believe, and what many will tell you, the cloud is not the same as next-gen server virtualization. It doesn't surprise me that many believe that by virtualizing their data center they will create a private cloud. Some vendors are intentionally trying to blur that line, aiming to convince customers that their vCenter clusters somehow deliver a private cloud. On the contrary, that is a gross exaggeration of the term cloud.

If you take a look at the way Amazon has built its cloud architecture, it becomes very clear that there are some fairly stark differences between a server virtualization environment and a true cloud architecture.  While Amazon starts with Xen virtualization technology, the brains of its architecture comes with a new layer of software that Amazon built in an effort to create a new control plane, a new cloud orchestration layer that can manage all the infrastructure resources (compute, storage, networking) across all of their data centers. This is at the heart of the cloud's technology disruption.  Some analysts refer to this as the "hypervisor of hypervisors," or a "new software category of cloud system software."

The fact of the matter is that some of the major players are doing cloud without server virtualization. Take Google for example. They have deployed a cloud architecture that is not using server virtualization, but rather a bare metal infrastructure. So while virtualization can be an important ingredient of cloud, it is not always a requirement.

3. Cloud is not an island. Depending on what you're reading, you'll hear a lot about public clouds versus private clouds, and it may feel as if enterprises must make a wholesale decision on which way to go. But the cloud is not an island, it is not a place where you put all of your IT services, and then lose all interconnectivity and access. The recent Amazon outages have proven this to be an important point for any organization leveraging the cloud. The right cloud strategy will be one that enables you to have a hybrid approach with the ability to easily connect private and public clouds. Even the recent move by NASA to include Amazon Web Services as part of its cloud rollout after a significant investment in the build-out of its own technology proves that the market is moving to open, interoperable multi-cloud environments.

4.  Cloud is not top-down. The cloud has up-ended the traditional IT approach to delivering services. The lines of business have been leading the charge in making the decision to move to cloud computing. With specific needs to get to market quickly, functional business leaders are consuming cloud services to avoid traditional IT processes. But we don't need surveys to clarify this movement.  The reality is that with the simple swipe of a credit card and the creation of an account, end users can...

How Much Should a Small Business Pay for a Website?

How Much Should a Small Business Pay for a Website?

I just met with a potential new client who is looking to move past her company's first (free) website and really build the internet as a referral stream. The client is smart, and their 8 year old business is successful. Thus far the referrals have been coming via word of mouth, networking, and limited and sporadic print advertising. The primary reason they haven't invested in the internet is their lack of understanding of how to do it effectively. This small business owner was scared off by many horror stories, including one scenario where her small business owner friend paid $10,000 for a website that brings in NO leads.

Unlike many business owners, this one came to our meeting prepared with a budget they could afford, but also was willing to be 'educated' on what marketing on the internet means. Here's what I told her:

1. Yes, you can get a decent website for under $2,000 depending upon your needs and how much fancy programming you require.

2. You need to not only consider your initial investment, but understand that you will need to be tending your website regularly; it needs to grow and evolve over time. $2000 may be ok for now, but you need to budget for regular updates, alterations and most importantly, additions to your site.

3. Building the website is only the beginning; in order to get leads from your site you need to first of all show up when someone searches for your service. That requires a long term commitment to organic SEO – search engine optimization, and very probably a commitment to pay per click advertising while you work on building your ranking organically on the...

New Bath Gel Doesn't Need a Tub

Rub-a-Dub-Dub: New Bath Gel Doesn't Need a Tub

Date: 20 June 2012 Time: 10:28 AM ET



For people who don't have time to bathe or access to fresh water, a South African college student has a solution: a shower gel users simply rub onto their skin. One small packet replaces one bath, and users never need any water. Ludwick Marishane's inspiration was a lazy friend, but his invention will be a boon to people who live in areas where clean water is in short supply. 

The gel, called Drybath, kills germs, moisturizes the skin and exudes a pleasant, light smell, unlike hand sanitizers, according to Marishane's website, Headboy Industries. The gel is packaged in small, easy-to-open sachets that were a South African invention.

Marishane got the idea to sell individual packets when he learned from mentors that the world's poorest people buy things in very small quantities, such as one cigarette at a time as opposed to a pack or a carton, he said in a presentation.

In poor communities, Marishane said he sells Drybath for 50 cents a packet, according to an interview with the Global Student Entrepreneur Awards. (Marishane won the competition's top prize in December 2011.) For corporate customers, such as airlines or hotels, each Drybath packet costs $1.50. Marishane donates one packet to charity for every corporate packet sold. 

Marishane, who is 22 and attends the University of Cape Town, got his inspiration as a teenager growing up in a rural part of South Africa. He recalled that once, when he nagged a friend to take a shower, his friend ( more at http://www.livescience.com/21060-rub-dub-bath-gel.html )

Why Smart People Are Stupid

Why Smart People Are Stupid

Editors' Note: The introductory paragraphs of this post appeared in similar form in an October, 2011, column by Jonah Lehrer for the Wall Street Journal. We regret the duplication of material.

Intelligence-Stvenson.jpg

Here's a simple arithmetic question: A bat and ball cost a dollar and ten cents. The bat costs a dollar more than the ball. How much does the ball cost?

The vast majority of people respond quickly and confidently, insisting the ball costs ten cents. This answer is both obvious and wrong. (The correct answer is five cents for the ball and a dollar and five cents for the bat.)

For more than five decades, Daniel Kahneman, a Nobel Laureate and professor of psychology at Princeton, has been asking questions like this and analyzing our answers. His disarmingly simple experiments have profoundly changed the way we think about thinking. While philosophers, economists, and social scientists had assumed for centuries that human beings are rational agents—reason was our Promethean gift—Kahneman, the late Amos Tversky, and others, including Shane Frederick (who developed the bat-and-ball question), demonstrated that we're not nearly as rational as we like to believe.

When people face an uncertain situation, they don't carefully evaluate the information or look up relevant statistics. Instead, their decisions depend on a long list of mental shortcuts, which often lead them to make foolish decisions. These shortcuts aren't a faster way of doing the math; they're a way of skipping the math altogether. Asked about the bat and the ball, we forget our arithmetic lessons and instead default to the answer that requires the least mental effort.

Although Kahneman is now widely recognized as one of the most influential psychologists of the twentieth century, his work was dismissed for years. Kahneman recounts how one eminent American philosopher, after hearing about his research, quickly turned away, saying, "I am not interested in the psychology of stupidity."

The philosopher, it turns out, got it backward. A new study in the Journal of Personality and Social Psychology led by Richard West at James Madison University and Keith Stanovich at the University of Toronto suggests that, in many instances, smarter people are more vulnerable to these thinking errors. Although we assume that intelligence is a buffer against bias—that's why those with higher S.A.T. scores think they are less prone to these universal thinking mistakes—it can actually be a subtle curse.

West and his colleagues began by giving four hundred and eighty-two undergraduates a questionnaire featuring a variety of classic bias problems. Here's a example:

In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

Your first response is probably to take a shortcut, and to divide the final answer by half. That leads you to twenty-four days. But that's wrong. The correct solution is forty-seven days.

West also gave a puzzle that measured subjects' vulnerability to something called "anchoring bias," which Kahneman and Tversky had demonstrated in the nineteen-seventies. Subjects were first asked if the tallest redwood tree in the world was more than X feet, with X ranging from eighty-five to a thousand feet. Then the students were asked to estimate the height of the tallest redwood tree in the world. Students exposed to a small "anchor"—like eighty-five feet—guessed, on average, that the tallest tree in the world was only a hundred and eighteen feet. Given an anchor of a thousand feet, their estimates increased seven-fold.

But West and colleagues weren't simply interested in reconfirming the known biases of the human mind. Rather, they wanted to understand how these biases correlated with human intelligence. As a result, they interspersed their tests of bias with various cognitive measurements, including the S.A.T. and the Need for Cognition Scale, which measures "the tendency for an individual to engage in and enjoy thinking."

The results were quite disturbing. For one thing,... ( more at http://www.newyorker.com/online/blogs/frontal-cortex/2012/06/daniel-kahneman-bias-studies.html )
