Testing the Limits of Google Translate

Google Translate is an amazing thing.  You can take a chunk of text in just about any language, paste it into Google Translate, and it is instantaneously (if imperfectly) translated.

Since I can’t speak anything other than English, I’m not in a great position to say how good or bad the translations are, but my multi-lingual friends generally turn their noses up at Google Translate, saying it doesn’t do that great a job.

My response is that compared to any other alternative I know (like trying to track down someone who speaks Croatian, or going word by word through a Croatian-English dictionary), it seems like a miracle.  I love it.

But even Google Translate has its limits.



The Economic Value of 3D Printing?

On a visit to the London Science Museum, my oldest grandson explained to me how 3D printing works.  I expressed doubt about its economic value, but he pointed out this sign.  “Aha,” I said, “here is a clear-cut case of a technological change that should reduce long-run average cost (by saving on materials).”

And despite the last sentence of the picture, this saving will eventually be passed onto consumers in the form of lower ticket prices, but probably not fully in the oligopolistic aircraft manufacturing industry.

What Does the Mt. Gox Meltdown Mean for Bitcoin? Maybe Not Much

Due to popular demand, we are working on a podcast about Bitcoin. Last night, I interviewed Marc Andreessen on the subject. His v.c. firm has invested roughly $50 million in Bitcoin-related companies, including CoinBase, and they are looking for more. It was a fascinating interview, in part because Andreessen has been personally involved in so many major digital events of the past 20 years. 

In light of today’s news about the meltdown of Mt. Gox, the most prominent Bitcoin exchange to date, here is a preview of a section of last night’s interview with Andreessen. His view is vigorously contra the notion that the end of Mt. Gox would mean the end of Bitcoin; in fact, he would take that as a sign of progress:



A Safe Hitchhiking Model?

Our podcast called “Where Have All the Hitchhikers Gone?” got a listener named Jenny O’Brien thinking. Here’s what she wrote us:

Here’s the back story: I live in a rural area in Northeast Kansas, where there is no bus, so I am forced to drive all the time.  After I heard your podcast, I started thinking about how to make hitchhiking safe, easy and reliable so I and other rural residents can use it as a public transportation option. I figured that all the hitchhiker really needed was a credential, way to signal her destination, and a system to record who she is riding with for safety.

O’Brien is now in the process of founding a ride-sharing service called Lawrence OnBoard:



3D Printers for Everyone?

We’ve blogged before about the potential of 3D food printers, but at the moment such printers seem out of reach for the average consumer.  Perhaps not for long — a new paper by B.T. Wittbrodt, A.G. Glover, J. Laureto, G.C. Anzalone, D. Oppliger, J.L. Irwin, and J.M. Pearce conducts a cost-benefit analysis of 3D printers for the average household:

This study reports on the life-cycle economic analysis (LCEA) of RepRap technology for an average U.S. household.  A new low-cost RepRap is described and the costs of materials and time to construct it are quantified.  The economic costs of a selection of twenty open-source printable designs (representing less than 0.04% of those available), are typical of products that a household might purchase, are quantified for print time, energy, and filament consumption and compared to low and high Internet market prices for similar products without shipping costs.  The results show that even making the extremely conservative assumption that the household would only use the printer to make the selected twenty products a year the avoided purchase cost savings would range from about $300 to $2,000/year.  Assuming the 25 hours of necessary printing for the selected products is evenly distributed throughout the year these savings provide a simple payback time for the RepRap in 4 months to 2 years and provide an ROI between>200% and >40%.  As both upgrades and the components that are most likely to wear out in the RepRap can be printed and thus the lifetime of the distributing manufacturing can be substantially increased the unavoidable conclusion from this study is that the RepRap is an economically attractive investment for the average U.S. household already. It appears clear that as RepRaps improve in reliability, continue to decline in cost and both the number and assumed utility of open-source designs continues growing exponentially, open-source 3-D printers will become a mass-market mechatronic device.

Can Connectivity Kill?

The standard narrative around technology in the developing world usually focuses on the positive: cell phones make it easier to check crop prices, transfer money, and understand violence.  But a new study, summarized in Foreign Policy, finds that all this connectivity can also increase political violence in violence-prone regions and countries:

new study by Jan Pierskalla of the German Institute of Global and Area Studies and Florian Hollenbach of Duke University looks at the relationship between mobile phones and political violence in Africa. They found that from 2007 to 2009, areas with 2G network coverage were 50 percent more likely to have experienced incidents of armed conflict than those without. The clearest overlaps between cell coverage and violence were observed in Algeria, the Democratic Republic of the Congo, Kenya, Nigeria, Uganda, and Zimbabwe.

The authors think that improved cell-phone coverage helps insurgent leaders overcome what’s called the “collective-action problem” — that people are reluctant to join group endeavors when there’s a high level of personal risk. But better communication helps leaders recruit reluctant followers, whether they’re demonstrating for higher wages or killing people in the next town.



NASA to Print Pizzas; Free Delivery Unlikely

In our podcast “Waiter, There’s a Physicist in My Soup!,” we talked to  Pablos Holman at Intellectual Ventures about food printers (we’ve also blogged about organ printers and meat printers). Now NASA is funding an Austin, Tex., company that is working on a pizza printer. From CNET:

Systems and Materials Research recently received a $125,000 grant from NASA to make a pizza. OK, it’s a little more complicated than that. Contractor already created a proof-of-concept printer that can print chocolate onto a cookie. His next goal is to print out dough and cook it while printing out sauce and toppings.



How to Solve the "Reply-All" Problem?

E-mail has been around long enough for most of us to fall in love and hate and love with it at least a few times. Problems arise and are quashed, or dealt with. Innovations come along; customs evolve. But one grisly bad habit won’t go away: the “reply-all” dilemma. You know what I’m talking about. Someone sends you a group e-mail. Maybe it’s your company’s marketing boss, or the head of your bowling league, or the parent-teacher liaison in your kid’s school. And even if that e-mail was meant to be simply explanatory, or to garner responses only to the sender, inevitably a few of the people on the receiving end simply hit “reply all” and suddenly your in-box starts to fill up with a chattering storm of crap. Sure, you could mark all those senders as spam but then you might miss something important later. Sure, you could politely tell people not to use “reply-all” when it’s unnecessary but plainly they don’t think it’s unnecessary, and you’ll come off sounding like a jerk. Sure, you could just deal with it and chalk it up to a downside of a great invention. But does anyone have any better ideas?



Why Cell Phone Networks Crash During an Emergency

Maggie Koerth-Baker of BoingBoing interviews Brough Turner, a phone system expert, about why it’s hard to make cell phone calls during an emergency. Turner addresses the mechanics and limitations of cell phone networks and points out that, nostalgia notwithstanding, the pre-cell phone era faced its own technical problems:

Well, say you’d have an earthquake in California. This was for the old Bell system. The national long distance routing has a set of standard, predefined routes and it had network control centers in New Jersey and other places. Things would get overloaded and they would manually intervene by putting access restrictions on new calls coming into the area that was congested. In the 60s, 70s, and 80s they would let through one out of every five call attempts. They were doing that manually and just arbitrarily to reduce congestion.

When Hacking Is the Smaller Crime

Here’s a fascinating article in the Yale Journal of International Affairs, by Paul Rexton Kan of the U.S. Army War College, about cyberwar between non-state agents — in this case, Anonymous versus Los Zetas, the Mexican drug cartel. Read the whole thing; here’s the first paragraph:

In the fall of 2011, two clandestine non-state groups—a hacktivist collective and a Mexican drug cartel—stared each other down in the digital domain, with potentially fatal real world consequences for both sides. Los Zetas, a Mexican drug trafficking organization composed of former members of Mexico’s Special Forces, kidnapped a member of Anonymous, the global hacking group, in Veracruz on October 6th. In retaliation, Anonymous threatened to publicize online the personal information of Los Zetas and their associates, from taxi drivers to high-ranking politicians, unless Los Zetas freed their abductee by November 5th. The release of this information on the Internet would have exposed members of Los Zetas to not only possible arrest by Mexican authorities, but also to assassination by rival cartels. Unconfirmed reports suggest that Los Zetas then attempted to “reverse hack” Anonymous to uncover some of its members and to threaten them with death. As a consequence, a few members of Anonymous sought to call off the operation and disavowed those members who wanted to go forward. With time running out and locked in a stalemate, Los Zetas released their kidnap victim on November 4th with an online warning that they would kill ten innocent people for each name that Anonymous might subsequently publicize. Anonymous called off its operation; each side appeared to step back from the brink.

Forget About Anchored Putters…This Is What the USGA Should Really Be Doing

Last week, the governing bodies of golf announced a ban on anchored putters.  Historically, when golfers putt (i.e. roll the ball along the green to try to get it into the hole), they swing the putter back and forth freely.  In recent years, a growing number of golfers have used a different technique, wedging the butt end of the putter into their stomach, or resting it against their chin.  For a variety of reasons, the head honchos of golf are against anchoring the putter.  I don’t have a strong opinion pro or con on this decision.  My hunch is that a careful data analysis would show that anchoring the putter doesn’t do much to help or hurt most golfers.  (For instance, I am about equally bad either way.)  Golfers who don’t play in tournaments can continue to use anchored putters if they like.  Tournament golfers will adjust.

In my view, the attention given to anchored putting is a distraction from the real issue that bedevils golf: pros hit the ball too far and everyday golfers hit the ball too short.  Pros hitting the ball too far is a problem because there is a huge stock of old golf courses, the value of which are greatly depreciated by the increases in distance.  Classic old courses aren’t hard enough to challenge the pros.  In response, large investments are made to stretch the distance of these courses to keep up.  And changes in the tournament courses alter the perceptions of golfers.  The course I grew up playing was hard enough when I was a kid, but now is perceived as too easy because it doesn’t compare to the championship courses. 



The Hidden Upside of Crowdfunding?

Reader Noah Dentzel claims that crowdfunding has overlooked virtues, and that it is giving rise to products that may never have happened via the traditional business model:

Most companies either a) raise money through traditional financing avenues or b) build a business slowly and invest first and then bring a new product to market. Crowdfunding allowed us to do everything backwards: by pre-selling a product before the tooling for it even exists, we get a good feeling for market demand and we then gain a clear picture of whether or not to move forward.

Meanwhile, because companies like us are financed through consumers (pre-selling), it’s essentially consumer driven business growth and innovation. We don’t have to wait around for angels or VCs, we can allow anyone from around the world (and a good third of our orders are from overseas) to invest in new ideas, new businesses and whatever will be crowdfunded next. What’s also pretty cool is that we’re making this product right here in California which isn’t too typical for a consumer electronic device these days. People ask why we’re not doing it in China and I just tell them that both in terms of quality and cost, we couldn’t afford it if we wanted to–these are some of the twists and turns that you see in the Crowdfunding consumer product long tail of manufacturing.

Check out Noah’s project here. Crowdfunding can, of course, also give rise to products like this.



Massimo Young Reports from Kenya: The Surprising Secret to Banking Success

My good friend Massimo Young recently moved to Kenya, where he is seeing what happens when you mix a little American ingenuity into a thriving but chaotic developing economy.  In what I hope is the first of many blog posts, Massimo reports on just what it takes to succeed in the banking industry in Kenya.  (Massimo does not have a financial interest in any of the companies discussed in his post, although he wishes he did!)

M-PESA: The Story of the Most Successful Bank in Kenya
By Massimo Young 

It’s not easy to do business in Kenya. Business people complain all the time that despite a wealth of opportunities, there are often major roadblocks to accomplishing much on the ground, especially at scale. In fact, Kenya ranks 121st out of 185 countries in the World Bank’s “Ease of Doing Business” survey.

On the other hand, there are some amazing examples in recent years of businesses that have managed to accomplish a lot very quickly. In particular, the wild success of mobile banking in Kenya has changed the way people use money here. Launched just 5 years ago, Kenya’s leading mobile money transfer service, M-PESA, now processes a total of about $5 billion in transactions per year, equivalent to an astounding 15% of the country’s GDP. Before it launched, only 14% of Kenyans participated in the formal banking sector. Today, about half the adult population uses M-PESA.



What Will the Smartphone Kill?

Today’s smartphone, it is often said, has more computing power than an Apollo rocket.

So it should not be surprising that is it disrupting daily life left and right. Every day or two I seem to notice another common item whose usage is plummeting, perhaps bound for oblivion.

I will likely never buy an alarm clock again since my phone can handle the job better. Are clocks and wristwatches on the way out? Has anyone bought a road atlas lately — or even a dedicated GPS system for your car?



The Economics Revolution Will Be Televised

There’s a revolution underway in economics. It’s not due to the financial crisis, but rather something more mundane: Data, and computing power. At least that’s the claim that Betsey Stevenson and I make in our latest Bloomberg View column:

“Consider the stream of data you will create today. Your metro card will record what time you caught the train. Your Web browser will note how you go about your job, and how much you procrastinate. A mid-afternoon purchase at Starbucks will reveal your penchant for lattes and the occasional cookie. Your flow of e-mail traffic will trace out your professional and personal networks.

At the same time, computing power has made it extremely easy and cheap to analyze all the data you produce. An economist with a laptop can, in a matter of seconds, do the kind of number crunching it used to take a roomful of Ph.D.’s weeks to achieve. Just a few decades ago, economists used punch cards to program data analysis for their empirical studies.”

Two weeks ago, Harvard’s Raj Chetty gave a spectacular talk at the National Bureau of Economic Research, about what he called “The Transformative Potential of Administrative Data.” He documented that today’s cutting-edge research is based on crunching newly-available data from the vast databases which underlay our schools, welfare state and tax systems.  I’m just as optimistic that new data coming online from the private sector will prove to be just as useful.



Help Wanted: Techno Superstars Looking to Work on Some Freakonomics-Inspired Start-ups in Chicago

I’ve got a lot of smart friends, and they come up with some pretty good ideas.  (I even have an idea myself once in a while!)

Occasionally, these ideas take the form of potential internet businesses.  Although we have incubated some interesting businesses up until now, there is too much talking and not enough doing.

It is time for that to change, and we want to open up  a little Chicago office to pursue these ideas.

We need some superhuman talent to make it a success.

Ending the Math Wars in a Treaty of QAMA

As a country, we are often at war. If it’s not against Germany, England, terrorism, or Grenada, it’s the war on poverty (that’s gone so well), the war on cancer (ditto), and, of particular interest to me, the Math Wars, which have been raging for decades. On one side, the traditionalists insist on drilling and back to basics, “on behalf of sanity and quality in math education.” On the other side, the reformers insist on conceptual understanding using computers and calculators, to “promot[e] the rational reform of mathematics education.”

Both are half-right and half-crazy. As the reformers say, students need to understand what the mathematics means. Students whose word problem for “6 x 3 = 18” is of the form “There were 6 ducks, and 3 more showed up, so 6 times 3 is 18,” understand little. (See “Children Learning Multiplication, Part 1,” in the articles by Professor Thomas C. O’Brien.) As the traditionalists say, using computers for everything leads to needing a calculator to compute what 6.5 x 10 is.

However, there’s a tool to combine the merits of both sides: the Quick, Approximate, Mental Arithmetic (QAMA) calculator.



The Ongoing Battle Between Technology and Human Behavior

“It is conventional wisdom that it is possible to reduce exposure to indoor air pollution, improve health outcomes, and decrease greenhouse gas emissions in the rural areas of developing countries through the adoption of improved cooking stoves,” write Rema Hanna, Esther Duflo, and Michael Greenstone in their new working paper “Up in Smoke:  The Influence of Household Behavior on the Long-Run Impact of Improved Cooking Stoves” (abstract; Washington Post coverage).

But, as the scholars discovered, what seems like an obvious technology fix doesn’t always work. Because, remember, human behavior can be a lot harder to change than we think.

Or, put another way: bummer.



The Twitter I.P.A.

Almost a year ago, we posted here about patent trolling – when individuals and firms use patents as a tool to extract settlements out of defendants who wish to avoid expensive patent litigation, even when the target thinks it can ultimately win.

Because they can be so valuable, patents are a big source of litigation, especially in the tech industry. Apple and Samsung have been at each other’s throats over smartphone patents, as have Apple and Motorola. Microsoft has been battling with Motorola over whether its Xbox violates Motorola’s patents, and Microsoft has also threatened smartphone maker HTC.  Oracle sued Google, claiming Google’s Android cellphone operating system infringed on Oracle patents.  Microsoft sued Barnes & Noble, claiming that its Nook e-reader violates Microsoft patents. Apple and Google are now eyeing each other warily over “slide to unlock” technology that Apple has patented and accuses Google of copying in its Android smartphone operating system. Google, as a defensive move, paid $12.5 billion to buy Motorola’s portfolio of nearly 25,000 patents. 



Abundance Authors Diamandis and Kotler Answer Your Questions

We recently solicited your questions for Peter Diamandis, founder and CEO of the X Prize Foundation, and journalist Steven Kotler. They are co-authors of the new book Abundance: The Future Is Better Than You Think. Below are their answers about the need for jobs (it’s not what you may suspect), the distribution of wealth, and the technological breakthrough that led the price of aluminum to plummet. Thanks to everyone for participating. 

Q. How did you come up with the book’s cover art? It’s very eye-catching — but not obviously related to the subject matter. –nobody.really

A. The cover is actually directly related to the book’s message. The book is “wrapped” in aluminum foil and the story of aluminum is what opens Abundance. In short, during the early 1800s aluminum was considered the most valuable metal in the world. This is why the capstone to the Washington Monument is made from aluminum, and also why Napoléon III himself threw a banquet for the king of Siam where the honored guests were given aluminum utensils, while the others had to make do with gold.



Is the Future Really "Better Than You Think"? Ask the Authors of Abundance

On an early episode of Freakonomics Radio, we interviewed Peter Diamandis, founder and CEO of the X Prize Foundation. He was a great (and inspirational) guest. Now he has written a book with journalist Steven Kotler called Abundance: The Future Is Better Than You Think. From the flap copy:

Since the dawn of humanity, a privileged few have lived in stark contrast to the hardscrabble majority. Conventional wisdom says this gap cannot be closed. But it is closing — fast. The authors document how four forces — exponential technologies, the DIY innovator, the Technophilanthropist, and the Rising Billion — are conspiring to solve our biggest problems.



Surviving "the Tyranny of E-mail"

Like a plague of locusts, they give us no rest. They gobble our irreplaceable asset: our time. The faster we swat them away, the faster they arrive. Our modern locust plague is email.

Fortunately, I found The Tyranny of E-mail: The Four-Thousand-Year Journey to Your Inbox by John Freeman a week ago at the Harvard Bookstore, one of the few surviving independent bookstores in Cambridge, MA. Alas, the book was discounted to $5.99 — which probably means that it is on remainder. That is a shame, for it is a rich and thoughtful book, mixing history, analysis, outrage, and remedy.

The beginning of wisdom, it was said, is to call things by their right names. By that venerable standard, this is a wise book.



Why Does the Kindle Feel So Much Heavier Than the Nook?

As someone in a mixed marriage — that is, in our home we read on Kindles and Nooks (and also an iPad) — I got a laugh out of the following e-mail. It’s from a Buenos Aires reader named Pablo Untroib:

Hi guys, read your 1st book and I’m on my way to finish SuperFreakonomics, today it happened something that I thought you would be interested. First a little introduction:

Two months ago I purchased a Nook simple touch e-book reader, these gizmos aren’t that popular here in Argentina compared to USA, so my wife’s 1st reaction was, why you spent money on that thing? So I loaded it with some books, she likes and not a day passed then she said: this Nook is mine, you should get a new one for yourself. Strategic error on my side, I should had purchased two to start with.



A Technology Paradox

David Brooks, in his Times column today (emphasis added):

When I started covering presidential primaries, the best part was getting to know the candidates. We journalists would ride around in vans and buses with them and get an intimate look at what it’s like to endure this soul-destroying process. But the ubiquity of Web cams and tweets has ended that off-the-record culture. As the technology gets more open, the lines of political communications become more closed.

True enough, and I’m surprised that more people don’t consider this paradox.



The Perils of Technology, iPad Edition

These days, I read a lot of books on an iPad 2 using the Kindle app. It is for the most part a very good experience, especially for recreational reading. As millions of others have noted, having an electronic device loaded up with a mini-library of e-books is especially valuable while traveling, which is when I do a lot of my reading.

The other day, on vacation with the family, I came across a pitfall. I was reading the old football novel North Dallas Forty (thanks to Henry for the suggestion, and all of you for other suggestions). It’s pretty entertaining — especially the race stuff and drug stuff. As it happened, my 9-year-old daughter was curled up beside me reading her book (The Doll People). She took at look at what I was reading. Her eyes immediately found a four-letter word.



Cockpit Confidential: Debunking the Autopilot Myth

This is a guest post by commercial airline pilot Patrick Smith, who writes about the hidden side of the airline industry. You can read his writing for Salon.com here.

Cockpit Confidential: The Autopilot Myth
By Patrick Smith

One evening I was sitting in economy class when our jet came in for an unusually smooth landing. “Nice job, autopilot!” yelled some knucklehead sitting behind me. Several people laughed. I winced. It was amusing, maybe, but was also wrong. The touchdown had been a fully manual one, as the vast majority of touchdowns are.

I’ve been writing about commercial aviation for nine years – a job that entails a fair bit of myth-busting. Air travel is a mysterious realm, rife with conspiracy theories, urban legends, wives’ tales and other ridiculous notions. I’ve heard it all, from “chemtrails” to the 9/11 “truthers.” Nothing, however, gets under my skin more than myths and exaggerations about cockpit automation — this pervasive idea that modern aircraft are flown by computers, with pilots on hand as little more than a backup in case of trouble. And in some not-too-distant future, we’re repeatedly told, pilots will be engineered out of the picture entirely.



Taking Risks to Improve Government: Kenya and Georgia

McKinsey is out with a new report on government innovation in Kenya and the Republic of Georgia. It’s basically the story of how developing countries can harness technology to circumvent entrenched bureaucracy and make government both cheaper and more efficient.
Here are both cases in a nutshell, with a couple snippets from each:
Kenya:

Challenge: Nearly 40% of Kenyans live on less than $2 a day, and corruption is still cited as an ongoing challenge for citizens and businesses. The World Bank has reported, however, that if Kenya can sustain its recent growth rate, it’s on track to become a lower-middle-income country in the next decade. And a new constitution establishes the citizen’s right to access government information—a right that must now be implemented.



Does HDTV Increase Demand for Make-up Artists?

A major technical change in TV has been the introduction of HD broadcasting and receivers. For the same price you get higher quality, so this can be viewed as a rightward change in supply. This change has affected a surprisingly related market—that for make-up artists.
Now if you’re on television, as I discovered, every single “flyaway hair” is visible. Most of my hair flew away many years ago, but what’s left might still stick out and need careful laying down by a specialist. A make-up artist tells me that demand for her services has been helped tremendously by the introduction of digital broadcasting and HD receivers.

Why Has There Been So Much Hacking Lately? Or Is It Just Reported More? A Freakonomics Quorum

You don’t have to be all that sharp to see that there’s a lot of hacking going on lately. As I type, Rupert Murdoch and his allies are testifying before British Parliament over the mushrooming News of the World disaster. It seems like everyone on earth is getting hacked: consultants and cops, Sony and the Senate, the IMF and Citi, and firms ranging from Lockheed Martin (China suspected) to Google (ditto) to dowdy old PBS. But is there really more hacking than usual of late, or are we just more observant?
To answer this question, we put together a Freakonomics Quorum of cyber-security and I.T. experts (see past Quorums here) and asked them the following:

Why has there been such a spike in hacking recently? Or is it merely a function of us paying closer attention and of institutions being more open about reporting security breaches?



What Will Be the Consequences of the Latest Prenatal-Testing Technologies?

Here’s some big — and good — news on the birth-technology front, from Amy Dockser Marcus in the Wall Street Journal:

New, noninvasive blood tests are being developed for expectant mothers to find out if their babies have genetic conditions such as Down syndrome, without the risks of tests available now.
Pregnant women often opt for a prenatal test called amniocentesis that requires a needle to be inserted through the walls of the abdomen and uterus to draw a sample of the fluid surrounding the fetus. The test is uncomfortable and carries a small risk of miscarriage, as does another invasive test for genetic disorders called chorionic villus sampling, or CVS, that samples tissue from the placenta.
Now, scientists say new tests of fetal DNA sampled from a mother’s blood can be used to screen for Down syndrome, which occurs in one in 691 live births and causes cognitive disabilities. The new blood tests could be performed as early as nine weeks into a pregnancy—earlier than amniocentesis—and may be available as soon as the end of this year.
