This Kind of Guy is the Future of Education

Salman Khan of KhanAcademy.org

I’m biased, but there’s no question that I fundamentally believe that the future of education is online. Talking to my daughter yesterday, a student at the University of Minnesota, she’d mentioned how dismayed she was having to take the bus to campus, walk to the one class she had that day, sit in a lecture, and then go home. “What a waste of time,” she said, “But I have to go since my prof takes attendance.” So I inquired if they streamed the lecture online. “Are you KIDDING ME!?!” she exclaimed. “Most of these professors and TA’s can barely hook up their computers!

What you’re about to view is an excellent example of the types of teaching that are exploding on the ‘net. From Instructables to Howcast (the latter is where I learned how to fix the overflow valve on my toilet) to this young man, Salman Khan of Khan Academy, most of this sort of teaching will be pooh-poohed by traditionalists and seen as augmenting existing meatspace education in buildings.

Fortunately, people like Harvard Business School professor Clayton Christensen see things differently. Christensen has described the three stages of disruption, the status quo will first see disruptors like Khan as “crappy” and ignore them, then they’ll become “less crappy” and early adopters will flock to them, and when they become “good enough” is the tipping point when disruptors kill status quo industries and yes, education is an industry since they still teach using an industrial age, factory model.

Watch this six minute video (discovered via Sid Yadav) and you’ll see what I mean about what one disruptor guy is doing for math education:

It’s Fun To No Longer Trust Your Eyes…Isn’t it?

I used to be a bit disturbed over how simple it was to manipulate photographs. Now the video/film manipulation has far outpaced that and can make whatever vision the director has possible. I’ve now watched this video ten times and I still find it delightful to see what can be done with strategically placed green screens and matching footage. My favorite parts are the walk through Red Square in Moscow, the ship on fire and the snow scene probably shot in July in L.A.

Watching this also is heightened if you have an appreciation for the challenges in matching the lighting in the scene and other environmental conditions.

What happens when fun, photorealistic 3D characters are matched with this kind of realism? Though many say we’re a long ways off from being able to faithfully recreate a human digitally, I’m not so sure that we’re closer than people think. The fun aspect still exists with many 3d photorealistic characterizations — and it’s easier to pull off believability when it’s basically a major stepup from a cartoon (e.g., Toy Story, Up, Shrek) but what happens as the creation and rendering technology gets so good that it is indistinguishable from reality?

Heavy Rain is an upcoming game that has gamers all abuzz about its photorealism and you should watch this HD trailer (you have to watch a lo-res advertisement first so hang in there) to see why there is so much excitement. Yeah, it’s awesome. OK…it’s still easy to tell it’s a game.

But for how much longer?

London Photography Will Get You Arrested

Having spent time in the U.K., I’ve grown to love the country and especially London. At the same time I’ve been quite aware that the London police have continually been cracking down on “suspicious” photographers and yet another confrontation happened to what seems like a nice, reasonable guy out to photograph a Christmas celebration (via Cory Doctorow at BoingBoing) and he used his DSLR’s video function to record his arrest.

While I feel like I have 50% of the facts (e.g., we don’t see what he was doing as he photographed so can’t ascertain anything about his behavior) I still applaud him standing up to the police and not automatically handing over “his details” (i.e., his name, ID, etc.) without them telling him why he was being detained and specifically what he’d done.

For a country that could’ve easily succumbed to the tyranny of the Nazi regime — a government that didn’t allow their own citizens to do anything without having “their papers” on them at all times — I must admit not appreciating the irony in London police trampling on their citizen’s civil liberties. I do appreciate the tensions in London, what with their experiences with the IRA and other horrific acts of terrorism.

But anyone with half-a-brain and any technical chops knows how incredibly simple it would be for real terrorists to surreptiously photograph any spot, building or crowd without anyone being the wiser so it’s highly likely that this continued confrontational attitude by London police is akin to the security theater in the United States.

It also makes me wonder about my own behavior on a family trip to London a few years ago where I was probably “suspicious” as I photographed like mad near Downing Street, all the governmental buildings along Whitehall, waiting for my wife and kids as they souvenir shopped as I lurked by a pillar in Trafalgar Square snapping photos with my Nikon DSLR, and essentially playing the role of obnoxious tourist.

What will I be able to do next time I’m in London? For instance, I enjoy snapping photos of many things: alleyways; police cars; doorways; street perspectives; people; and crowds. Is my behavior going to cause confrontations with the London police? Probably, so I’ll undoubtedly be seeing the inside of a London jail but one that isn’t exactly geared to tourists!

A Penny Saved is Actually $0.17 Cents

This is the new design of the U.S. penny being minted now. The kicker? According to this March 2008 ABC News article, “It costs almost 1.7 cents to make a penny,according to U.S. Mint director Ed Moy. Each year, the U.S. Mint makes 8 billion pennies, at a cost of $130 million. American taxpayers lose nearly $50 million in the process. The penny’s not alone. It costs nearly 10 cents to make a nickel.

Why not just ditch the penny? “One reason there is a lasting attachment to those coins is because they are a part of our country’s history,” Moy said in that article. I’ll accept that or some of the other things I’ve read that it will kickstart inflation. Why? Because sellers will “round up” and not “round down” with prices so there will be an immediate jump in costs for everything from toothpaste to TVs.

How could technology make our paying with pennies more efficient? With more and more of us walking around with smartphones, micropayments may be one answer. This would be a method where each of us would have an account that incremental sums (i.e., amounts in pennies) would be sent to or subtracted from during a transaction. I shudder, however, when I think about all the systemic and behavioral changes something like that would require.

Funny (and admittedly tangential) story about pennies happened when I was 16 years old. There was a guy who owned a gas station near our house and he was a complete jerk and especially so to young people. My friend Jeff and I were in his Mom’s car and stopped for gas. The guy inadvertently put in $10 worth in the tank and we had $5 with us and Jeff had told him he wanted $5 worth…but the guy then blew his stack and threatened to call the police on us until we agreed to go get the $5 and come back (he also wrote down Jeff’s license number).

We came back an hour later and Jeff handed him a jar with 500 pennies. “Goddammit!” the owner screamed. “I don’t have to accept these pennies!” but Jeff put it on the counter and we turned around and left. The owner never did anything and, in fact, was out of business two years later (I assume for being a jerk and driving customers away).

When I think about micropayments, I’d actually like having an online slush fund for paying a penny, nickel or dime to read an article online. This would be trivial to do and might help fund an otherwise declining media base. But another thing to consider with payments becoming virtual are the privacy, free speech and other concerns. For a complete and exhaustive paper on the subject, read The Digital Imprimatur by Autodesk founder John Walker from 2003.

GoodGuide: Holding Producers Accountable

When I wrote yesterday’s post Food, Inc.: I will never look at dinner the same way again I intended to point out some tools you can use to make informed decisions about what you eat and the companies that are producing your foods.

GoodGuide is both a website and a free iPhone/iPod Touch application which allows we mobile users to “simply scan the barcode of the product and immediately see detailed ratings for health, environment and social responsibility for more than 50,000 products and companies. GoodGuide provides this information about personal care, household chemical, toy and food products for free on your iPhone / iPod Touch and is adding thousands of products every month. By making information about consumer products transparent, GoodGuide’s goal is to help people shop smarter and motivate companies to offer even better products.

On their homepage you can learn about the issues, see food recalls and other related news, and my favorite thing to do, browse ratings of other products. If you signup you can create a “Favorites” list and begin amassing a database of your preferred products.

Besides the obvious power this is putting in the hands of consumers, what’s most interesting to me (and to our clients) is how empowered consumers will likely have applications that go far beyond food product and the food distribution companies. Imagine you’re a furniture manufacturer and consumers can make choices to buy products from companies that don’t use formaldehyde. What would you do if your sales started to drop? You bet….start making formaldehyde-free furniture. (For more see the Wall Street Journal on “New Bill Could Limit Formaldehyde in Furniture” and SFGate’s article “What’s in furniture? It’s enough to make you sick“).

So if you’re primarily interested in being an empowered consumer, download the free GoodGuide and apps like it. If you’re in the business of producing goods or selling services that rely on other’s products, you’d better understand the entire supply chain of those goods and get ready for heightened awareness and accelerated choices by consumers!

Adobe Flash Roasts My ‘Chestnuts’ w/50% CPU Use

All the brouhaha about no-Flash on the Apple iPad, how great Flash is (by the Adobe folks) and how HTML5 will be the savior of us all is not lost on any of us in the tech community. So having experienced the resource needs of the hungry runtime known as Flash, I decided to do a quick-n-dirty experiment to see just how much CPU is used by the Flash runtime to play a video on my 2.33Ghz, Intel Core2 Duo, 4GB RAM, Macbook Pro.

Kara Swisher of AllThingsD interviewed Adobe CTO Kevin Lynch and posted the video today (in Flash, naturally). I thought it would be ironic to test the CPU use of Flash as a layman — a man who frequently has his “chestnuts” roasted from the nearly open fire of heat on the bottom of my Macbook Pro generated by the CPU being driven really, really hard by Flash — by playing his video in Flash and measuring its CPU utilization vs. a video played in HTML5 (on the YouTube beta site for HTML5 videos).

Bottom line? Flash uses on average 50% of my Macbook Pro CPU to play a video and HTML5 uses “in the teens” (15% – 19%). If you want to see more, watch this VERY rough and quick-n-dirty video (sorry about the cheesy audio) I did to show you why I’m pleased that, either Adobe make Flash awesome, or Apple NOT put it in to the iPad:

UPDATE: If you’d like to read one of the best overviews I’ve seen yet of the controversy — and whether or not the iPad even needs a Flash runtime for video or anything else — see this AppleInsider post entitled, “Inside Apple’s iPad: Adobe Flash“. It’s a three page article so be sure to read all the pages.

Food, Inc.: I will never look at dinner the same way again

One of the benefits of Netflix on-demand streaming is the number of documentaries I’ve had access to and am watching, one of which my daughter and I watched last night called Food, Inc., and the movie troubled both of us and I’m still thinking about it this morning.

I can’t find the reference for the article this morning, but there was a research study I read a few years ago that compared the “cost” of a calorie 200 years ago (what it took to grow, harvest, cook and eat a calorie) vs. the cost in effort and energy today. It was significantly greater in the past, of course, and the other statement that stuck in my mind was that the typical American household had more calories in their cupboards than the typical family ate in a month in 1850 (I’ll keep trying to find the data and do an update).

Watching this movie pointed out that the efficiencies of our industrial food system, combined with farm subsidies that keep costs for commodities at artificially low amounts, have kept costs low throughout the food creation and distribution system. While cheap calories have helped America become the envy of the world as we feed millions of us and others around the world, it has also caused us to opt for processed foods over raw veggies and meals that we have to cook and made half of we Americans fat (and I can attest to that!).

Usually I try not to be an alarmist, but the opacity of the industrial food system has become quite troublesome and this movie pointed it out better than anything I’ve ever watched. This is not my attempt to vilify the food industrial complex, but rather ensure that more of us demand to know what’s happening up the food creation chain so we know what we’re eating. I’ve often said that if people could take one tour of a cow, pig or chicken slaughterhouse we’d have a helluva lot of vegetarians in America, but same goes for the amount of crap that’s in our foods.

Take a peek at this trailer and I’d encourage you to rent it and then you can head over to their Food, Inc. website and take action. If it doesn’t open your eyes and change your habits, I’ll wave when I see you in the supermarket as you buy your big bag of Doritos and Jimmy Dean sausage for supper.

Steve Wozniak on Color Computing

When Apple released the Apple II at the West Coast Computer Faire in 1977, it was a big deal with its color display. Since I love poking around FORA.tv and watching the thought leader videos curated there, I was pleased to see this snippet of a Steve Wozniak (Woz) interview (you can watch the entire hour+ program here) about the spark of genius. The cool thing? As you listen and watch Woz describe how he came up with the idea to deliver color computing for a radically reduced price, it is the quintessential description of problem solving and creative solutions to problems.

This was recorded at the Bay Area Discovery Museum on February 1, 2010 and they describe it this way:

Steve Wozniak, Apple co-founder and philanthropist in conversation at the Discovery Forum 2010 with Emmy-award winning journalist Dana King from CBS 5 Eyewitness News.

Renowned technology pioneer Steve Wozniak speaks to the importance of hands-on learning and encouraging creativity, and how the Bay Area Discovery Museum is a critical resource for preparing children for the challenges of the 21st century.

The Discovery Forum serves to increase awareness about the importance of childhood creativity, and raises support for the Museum’s educational exhibitions and programs.

Watch this couple of minute segment (yes, there are ads first) and you’ll see what I mean about creative problem solving:

Thinking about my Dad

Being self-employed has its advantages which, fortunately, usually outweigh the disadvantages. One huge advantage is that I’ve been able to help out my Dad as he’s needed to go to the doctor, have surgeries and so on over the last few years. Today any possible downsides were far outweighed by my being free to take my 84 year old Dad to a followup-from-surgery doctor appointment and it’s made me realize how lucky I am to have him and to be free to help.

This is a guy who has become increasingly frail over the last few years and I’m always struck by how he doesn’t seem that way when he’s in his own house at his kitchen table. There he is in command of his environment and it’s as though nothing has changed. Decades of being a smoker have taken its toll on his lungs coupled with all the other stuff that goes on with a body after seven decades plus on earth, but the way time beats down on people as they age is only in evidence when we’re out of his house. He usually can take himself anywhere but recent needs have made having help from my sisters and I a necessity. I’m glad I can be there for him when he needs us (my three sisters are there for him too) and that I was able to take him today and at other times in the past. [Read more...]

Storytellers, Filmmakers & You

Prisoner by dub72 @DeviantArt

Archaeologists suggest that the written word has been around for about 6,000 years. Before that knowledge was disseminated amongst humans through storytelling. If modern humans have been hanging around the earth for about 200,000 years, that means that for 194,000 years we developed a pretty robust capacity to capture the essence and meaning of critical information through the telling of stories.

I’ve been slowly but surely seeking out great storytellers who are leveraging the internet TV/video delivery capability to create, edit and publish their stories. Since I’m less interested in watching a couple of kids lip-synching or dancing to their favorite artist on YouTube, I’ve been gravitating toward higher quality sites like Vimeo and watching these videos really gets the wheels turning in my head, especially when I poke around within their over 5,000 HD channels, often watching while on the treadmill through my Roku box connected to a 26″ HDTV in the exercise room (a room which is used frequently here in Minnesota in the winter!).

Sometimes the videos are goofy. Often they’re visually stunning with no point other than experimenting with the technology. Other times they’re just too long and the storytelling is painfully dull. All that said, the gems I find most of the time make poking around the others worth the effort and I often wonder who the next George Lucas or Steven Spielberg will be from this batch of budding filmmakers.

Last night on the treadmill I came across this sweet little story made by a woman named Karen Abad for her grad school cinematography class. It’s less than 3 minutes long, you should watch it until the end to “get” the point, and then check out the other HD channels to see some more great stories.
