rampart: fortification.

[There are a few new additions and updates to The Store. Check it out!]

So, The Pirate Bay was acquired by a “legitimate” company that plans to transform it into a “legitimate company.” I’m sure they’re banking on name recognition from all the media exposure and lawsuits to bring the honest non-eyepatch customers around. Remember how well that worked for Napster? [hint: not well]

YOUR COMMENT CHALLENGE: Assuming The Pirate Bay was a retail store (see the above comic for precident), give me some scenarios that might play in said store. How about bathroom signs that say “Employees must wash hooks before returning to work.” Or maybe OSHA guidelines demand all peglegs be made of spruce or maple.

Recently, I’ve noticed something. If you send me an email, the likelihood that I’m going to respond is pretty small. But if you send me a message on Twitter, the likelihood that I’ll respond is much higher. Certainly, part of it is that I get fewer messages on Twitter. But you might be surprised at how close it’s getting in volume when you add @replies to direct messages. The bigger factor for me, is the length of the messages.

If I open up an email and see it filled with paragraphs of information, guaranteed my eyes are going to glaze over. Certainly sometimes it’s an important message that I do need to read, but most of the time it’s just a core message filled with paragraphs of bloat. I don’t want or need the bloat, I need the core message. And that’s why I love Twitter. You simply cannot go over 140 characters. And more often than you may imagine, that’s enough.

Now, on the face of it, plenty of people will disagree with me on that point. But think about it. In an age where we’re bombarded by tons of information, from multiple angles, all day long, there is something beautiful about brevity.

I used to read screenplays for a living. Trust me when I say that there is no shortage of people who can blather on about something to seemingly no end. But the skill in writing a screenplay often came down to if you could convey what you needed to convey in just a few lines. It’s not an easy thing to do — at all. And while it’s not quite the same because it’s even more compact, Twitter forces you do to a similar thing in its own way. And Twitter is hardly the only form of communication that has done this.

Most users know by now that the 140 character limit of Twitter is actually tied to the limits of text messaging. Text messages can only be 160 characters long (Twitter needed to reserve the extra 20 characters for usernames). But do you know where the 160 character limit comes from?

The LA Times ran an excellent piece a few months ago about Friedhelm Hillebrand, the father of the modern text message. He dreamed up the 160 character limit while working at a typewriter in the mid-1980s, trying to see how long sentences needed to be to convey something. He found 160 characters was the magic number he kept arriving at. But the deciding committee for SMS still wasn’t sure until they looked at postcards and found that most of those had messages of 150 characters or less.

And so you see, while you may think Twitter’s character limit is silly or frustrating, it’s actually born out of two other forms of communication that are widely accepted and used the world over. You may not think of Twitter being just like a postcard, but in some ways it is — one that you can instantaneously send to many friends or acquaintances at the same time. And minus the cost of a stamp.

Even with the rise of technology, the lure of the short message remains. And that was the key reason why I found Twitter compelling when I first started using it over two years ago. I never thought of the limitation in a negative sense, but rather as something that could inspire creativity in messages. And could even spur communication.

It’s liberating to know that you only have 140 characters or less to respond to something. For a lot of messages, that removes a huge burden of trying to say enough to the person you’re talking to so that they don’t think you’re being rude. With a 140 character limit, a correlation between briefness and rudeness doesn’t exist.

And that’s why more and more I’m finding myself telling people, “Just message me on Twitter.” It’s a two-way street. I don’t want to have to read you go on and on about something that could be said in one line, and you won’t have to listen to me go on and on about something in response. Again, it won’t work for all messages, which is why Twitter or something like it will never kill email, but for a lot of messages, it works just fine.

Characters and time are saved. It’s a limitation that is liberating.

Over the last couple of days, there's been a great deal of coverage of three new studies on the genetics of schizophrenia. While the coverage has actually been pretty good, almost all the news stories make the same error when talking about the 'genetic risk' for the condition.

Twenty years ago, geneticists were searching for the 'gene for schizophrenia' until it became apparent that there was not going to be a single gene, or even a handful, found responsible for the mental illness.

It since became a mantra that the genetic risk for schizophrenia would be conferred by 'many genes of small effect'. In other words, the cumulative effect of lots of genes that, on their own, would be quite benign.

Nature has just published three studies that use the only-recently-feasible technique of scanning the whole genome and has reported the first convincing positive evidence for the 'many genes of small effect' theory by finding that a whole bunch of genes, when considered together, account for about a third of the total difference in schizophrenia risk.

Interestingly, all three studies find that many of the genes lie in a region called the 'major histocompatibility complex' - a series of genes involved in the function of the immune system.

However, lots of the news reports, even from science publications give variations on the theme that 'genetic factors account for 80 percent of the total risk of getting schizophrenia'.

This 80% figure (which can vary, some give 90%) is not an estimate of risk and shows a misunderstanding of estimated heritability taken from twin studies.

Luckily, I tackled exactly this issue in a column for July's edition of The Psychologist:

Nature versus nurture is a lie. Music is not melody versus rhythm, wine is not grapes versus alcohol and we are not environment versus genes. We are their sum, their product and their expression. They dance together and we are their performance, but neither is an adversary. The art of understanding this elegant ballet is complex and arcane but you may never realise this from reading the quoted results of genetic studies, because the extent to which a trait is heritable, that is, accounted for by genetics, is usually expressed as a simple percentage.

If you search Google for the phrase “80 percent genetic”, you will discover hundreds of sources that claim that everything from schizophrenia, to height, to intelligence has been found to be four fifths ‘genetic’. Pick any other figure and you can find everyone from psychologists, to politicians, to journalists claiming that this or that is explained by genes to a given percentage. Geneticists know the subtly of this percentage and why these statements, usually lifted from the results of twin studies, are misleading, but clearly many others do not.

Imagine a mental illness is described as being 80% heritable. This is often taken to mean that four fifths of an individual’s risk is down to his or her genes, but this is not the case. What it means is that 80% of the variance in the measured illness was explained by genetic factors in the specific group that was studied. If this seems like a frivolous distinction, bear with me, because it is key in understanding heritability and it becomes crystal clear when tackled as an example.

Imagine that we could study a population where everybody lived in an identical environment. They did the same things everyday; they ate identical foods, had identical relationships and were stressed by identical events. Their lives were carbon copies of each other. A twin study would find that mental illness would be close to 100% heritable, because if the environment is fixed, any difference must be down to genetics. In fact, twin studies would find that everything is close to 100% heritable, for exactly the same reason. To flip our thought experiment on its head, if we only studied genetically identical clones, everything would be 0% heritable, because any difference must be down to the environment.

These figures do not necessarily tell us anything about the potential for a trait to be influenced by nature or nurture, because heritability is rarely an immutable and absolute fact about biology; it is an overall measure of how things are for that group, at that moment. In other words, the process of measuring the influence of genetics is, itself, subject to environmental factors. It captures the dance, not the dancers.

A common bias among the smart is to overestimate how smart everyone else is.  This was certainly my experience in moving from top rank universities as a student to a mid rank university as a teacher.  A better intuition for common abilities can be found by browsing the US National Assesment of Adult Literacy sample questions.

For example, in 1992 out of a random sample of US adults, 7% could not do item SCOR300, which is to find the expiration date on a driver’s license.  26% could not do item AB60303, which is to check the “Please Call” box on a phone message slip when they’ve been told:

James Davidson phones and asks to speak with Ann Jones, who is at a meeting. He needs to know if the contracts he sent are satisfactory and requests that she call before 2:00 p.m. His number is 259-3860. Fill in the message slip below.

Only 52% could do item AB30901, which is to look at a table on page 118 of the 1980 World Almanac and answer:

According to the chart, did U.S. exports of oil (petroleum) increase or decrease between 1976 and 1978?

Only 16% could do item N010301, which is to answer “What is the purpose of the Se Habla Espanol expo?” after reading a short newspaper article called “Se Habla Espanol Hits Chicago; September 25,26,27 are three days that will change your marketing.” The article includes this quote:

It’s Mr. Martinez’s job—his mission in life—to make sure companies learn how they can serve and sell to America’s Hispanics. He has been marketing to the community for many years, working with the best in the business, including Coca-Cola and the advertising firm of Castor GS&B. Now his staff is organizing the largest annual Hispanic market trade show in the business—Se Habla Español.

Acceptable answers include statement such as:

To enable people to better serve and sell to the Hispanic community; to improve marketing strategies to the Hispanic community; and to enable people to establish contacts to serve the Hispanic community.

Only 11% could do Item N100701, which asks:

Using the information in the table, write a brief paragraph summarizing the extent to which parents and teachers agreed or disagreed on the statements about issues pertaining to parental involvement at their school.

I think an acceptable answer is to note that parents tend to have lower opinions than teachers of school performance.

Slatterz writes "The Tesla Roadster has almost mythical status among electric car enthusiasts. It's fast, with high torque over a wide RPM range, and can beat a Ferrari in terms of acceleration. Now Tesla has released new video of its upcoming new electric car, called the Model S, which Tesla Motors claims is the world's first mass produced fully-electric vehicle. Unlike the Lotus-Elise based Roadster, the Model S is a traditional sedan of the type millions of commuters might actually drive. Tesla claims it will fit seven people, and has mounted a rather large 17in LCD in the dash. Key to Telsa's future will be the evolution of lithium-ion battery technology. Tesla Motors claiming the new Model S can travel up to 300 miles on a single charge, but the battery will still take 45 minutes to quick-recharge." (And for those in countries where it matters, this article mentions that it should also be available in right-hand drive.)

Okay, it’s not exactly the Camp David Summit that took place in 2000 between the Israelis and the Palestinians, but sometimes the littlest gestures can go a long way.

A couple of days ago, upon hearing that Microsoft had officially joined Twitter, the official Linux account sent out a tweet welcoming them. “Welcome to Twitter, @Microsoft!,” they said. The tweet sat unanswered for over a day, and it seemed like Microsoft may never answer. But about a few hours ago, they did. “@Linux thanks, nice to be here,” they replied.

Short, sweet, and to the point. A sign of peace in the operating system ecosystem? Probably not. But it’s something — just look at the shirts that were going around in this war just a few years ago (above).

Twitter is turning into quite the sanctuary for rivals to at least pretend to be nice to each other. Just look at Coke and Pepsi the other day.

movesguy sends us to The Daily Galaxy for comments by Stephen Hawking about how humans are evolving in a different way than any species before us. Quoting: "'At first, evolution proceeded by natural selection, from random mutations. This Darwinian phase, lasted about three and a half billion years, and produced us, beings who developed language, to exchange information. I think it is legitimate to take a broader view, and include externally transmitted information, as well as DNA, in the evolution of the human race,' Hawking said. In the last ten thousand years the human species has been in what Hawking calls, 'an external transmission phase,' where the internal record of information, handed down to succeeding generations in DNA, has not changed significantly. 'But the external record, in books, and other long lasting forms of storage,' Hawking says, 'has grown enormously. Some people would use the term evolution only for the internally transmitted genetic material, and would object to it being applied to information handed down externally. But I think that is too narrow a view. We are more than just our genes.'"

It's not often that Internet companies last 10 years, but Moonfruit in the UK has proved pretty resilient. It survived the dotcom boom the first time round, launching with VC-backing, growing to 65 staff and cutting back to two staff in the space of a couple of years. It's a wonder why they didn't exit in the most recent boom, but here they are still, plugging away. And their resilience is proving to be an asset as their 10-years old web site building business comes back into fashion, even as more recent competitors like Weebly, Yola, MyDragnDrop and Webnode, and many others, try to capture the market for people who want to build simple web sites. So what's the best way to re-invigorate an internet brand after 10 long years? Get trending on Twitter, that's how. So Moonfruit has been giving away 10 Macbooks for every year of their operation, beginning this week. The result is that it has become the top trending term on Twitter three days in a row, as all people need to do is add the hashtag #moonfruit to their tweet. An algorithm is randomly choosing a winner. There are five days left. By the second day this week it had reached 2.5% of all twitter traffic. But could the stunt backfire as fast as it worked?

Basically, it’s this kid who does movie and new media reviews that are (or at least used to be) unintentionally hilarious. These days, he apparently has quite the following on YouTube, as he has over 150 videos that range in popularity from tens of thousands of views to over a million.

One of his most popular ones was a video from 4 months ago in which he calls out rapper 50 Cent. Sexman wonders how 50 still has “street cred” after doing endorsements for Vitamin Water, makeup and dildos (I’m not kidding). “What else is he gonna do? 50 Cent diapers for your little gangsta?,” Sexman wonders at one point. He concludes that 50 Cent is “just a media whore!”

Well, 50 Cent has responded. Yesterday, the rapper posted a video alongside Sexman, who apparently flew from Canada to New York to meet up at the rapper’s request.

cheezitmike writes "Researchers at Oregon State University are testing a new type of wave-energy converter to generate electricity from ocean waves: 'Even when the ocean seems calm, swells are moving water up and down sufficiently to generate electricity. ... For decades the challenge has been to build a device that can withstand monster waves and gale-force winds, not to mention corrosive saltwater, seaweed, floating debris and curious marine mammals. ... In the most recent prototypes, a thick coil of copper wire is inside the first component, which is anchored to the seafloor. The second component is a magnet attached to a float that moves up and down freely with the waves. As the magnet is heaved by the waves, its magnetic field moves along the stationary coil of copper wire. This motion induces a current in the wire — electricity.'" Meanwhile, researchers at Stanford are working to design "turbine kites" that operate at 30,000 feet, where air currents flow much faster than they do close to the ground. Ken Caldeira, a Stanford associate professor, said, "If you tapped into 1% of the power in high-altitude winds, that would be enough to continuously power all civilization."

Before everyone gets in a huff, let's consider Amazon's intentions with these patent applications. Surely they would never allow advertisements to be placed in books which you have purchased legitimately at full price, so let's put that out of our heads. But what if you could take a few bucks off the cover price at the cost of a few contextual ads relating (if possible) to the book's content? Personally, I wouldn't mind — partially because I don't use a Kindle or intend to any time soon, but more because it's a no-lose situation. Amazon wouldn't risk alienating its loyal Kindle base with dirty tricks like this, so it's safe to assume it'll be at least somewhat opt-in. An abundance of free or reduced-price content would widen the appeal of the reader — I imagine many people are put off e-books by the idea that they are not getting their money's worth. As offensive as the idea of inserting ads into a book is to me (and surely to the average reader), it's almost certainly part of a value proposition which increases the utility of these expensive little buggers.

This post is about amateur physics. No computer science is involved, but it was pretty cool.



In 1798 Henry Cavendish did an experiment to weigh the world. Although Cavendish didn't bother deriving the gravitational constant, his experiment was the first that could produce a direct measurement of it.



In the summer of 1985 I was at home convalescing and being bored. It occurred to me one day that if Cavendish could determine the gravitational constant back in 1798, I ought to be able to do something similar, especially because I had access to a few things that were a little hard to obtain in 1798.

The Cavendish experiment involves a torsion balance, which is like a dumbbell which is suspended in the middle by a thin fiber. After letting the thing settle down for a long time, it will be very sensitive to forces that cause it to rotate in the horizontal plane. But any rotation will be opposed (very slightly) by the torsion on the fiber. By placing a pair of large masses near the weights on the end of the dumbbell, the gravitational attraction between the masses will cause the dumbell to rotate until the force of gravity matches the opposing force of the torsion. If we can measure the angle of rotation and determine the torsion of the fiber, we can derive the gravitational attraction between the masses.



Cavendish cast a pair of 1.61 pound lead weights. I found a couple of 2-pound lead cylinders my dad had lying around. I used duct tape to attach them to a 3-foot wooden dowel. Cavendish used a wire to suspend the balance, I used nylon monofilament. To determine the torsion of the fiber, you wait until the balance stops moving (a day or two) and then you slightly perturb it. The balance will slowly oscillate back and forth. The restoring force is calculated from the period of oscillation. Cavendish had a 7-minute period. My balance had a 40 minute period (nylon is nowhere near as stiff as wire).



Cavendish used a pair of 350 pound lead balls to attract the ends of the balance from about 9 inches away. I put a couple of 8 pound jugs of water about an inch away. The next trick was to measure the rotation of the balance. Cavendish had a small telescope to read the Vernier scale on the balance. I used some modern technology. I borrowed a laser from Tom Knight (Thanks again!), and bounced it off a mirror that I mounted on the middle of the balance. This made a small red dot on the wall about 20 feet away. (I was hoping this would be enough to measure the displacement, but I was considering an interferometer if necessary.)



To my surprise, it all worked. After carefully putting the jugs of water in place, the dot on the wall started to visibly move. Within a few minutes, it had moved an inch or two. I carefully removed the jugs of water and sure enough, the dot on the wall drifted back to its starting position.



This was really cool. Newton's theory of gravity was the first ‘unified theory’ of physics. It took several disparate phenomena — the orbits of the planets, the orbits of moons, tides, and the kinematics of falling objects — and proposed a single theory that explained them all mathematically. But Newton's theory supposed that every object has a slight gravitational attraction to every other. This is a strange phenomenon that hadn't been observed (prior to Cavendish). It's not something you usually see because the force is extraordinarily small.



My dad was astounded. Of course he knew about gravity from high school, and knew it kept the planets in orbit and stuff stuck on the ground, but he hadn't remembered (or perhaps wasn't taught) that there was a very small gravitational force between everything, including the lump of lead on the end of my stick and the jug of water a few inches away.



Even though I knew there was a force I could measure, it was still pretty amazing to watch it happen. Sure, you believe Newton's laws, but after seeing this in action, there is still a `wow' factor.



Now as for the value of G. I think I gave enough information here for someone to derive it. I think I calculated it to be somewhere around 10^^-11 plus or minus an order of magnitude. One day I might try to really calculate it.



I have to recommend trying this experiment if you have the room to set it up. It's something to see.

This week, an advisory committee to the Food and Drug Administration raised a red flag about a very popular and very effective painkiller — acetaminophen. The panel of experts has recommended lowering levels of acetaminophen in prescription and over-the-counter drugs because of concerns about liver damage.

Investigators have called the sailor’s death a random act unrelated to the his sexuality and have taken a “person of interest” into custody. No charges have been filed.

“He went to the Navy to serve and protect,” she said in an interview with Beaumont’s KFDM News, “he didn’t get protected at all.”



Roy told The Associated Press that the military’s “Don’t Ask, Don’t Tell” policy discouraged her nephew from asking for help.



“That phrase is just stupid because it tells them they have no one to speak to,” she said.

It’s not easy to launch a successful WebEx competitor. Most businesses have long since established their “system” for dealing with web meetings, using old standbys like WebEx or GoToMeeting. And those businesses that are willing to venture into the unknown have had plenty of cheaper alternatives to choose from, like DimDim, for quite a while. But that isn’t keeping CallWave from launching one of its own, dubbed Fuze Meeting. And while it’s not going to be an easy space to compete in, Fuze Meeting doesn’t disappoint.

As far as startups go, the history of the company is pretty unique. CallWave was founded in 1998 and went public in 2004, trading on NASDAQ under the ticker symbol CALL. After reaching a peak soon thereafter of over $15 per share, the stock dropped steadily, dipping as low as 50 cents early this year. Deciding to cut its losses, the company delisted itself from NASDAQ on Monday after buying back shares from public shareholders at a 44% premium over the current market value and paying out a total of $10 million. CMO Patrick Moran says that the company did this on its own accord, and that its hand wasn’t pushed by any banks or VCs. CallWave will soon change its name to Fuze Box to reflect its new position as a startup.

While all of this has been going on, CallWave has been building the “fuze platform” that powers Fuze Meeting, which it’s pitting as a sleeker, lighter, and cheaper alternative to services like WebEx. Last fall, the company decided to show off an early version of the product to some press, perhaps prematurely (it was labeled as “incomplete” by CNET). Finally in May, a full eight months after making its public debut, Fuze Meeting finally became commercially available. And only now that the company’s financial wranglings are complete is it ready to really announce it to the public.

I played around with the complete version yesterday, and for the most part I was impressed. The application is slick and intuitive, and unlike some other screen sharing apps, Fuze Meeting requires no plugins — it should work on just about any browser, and also offers support for both the iPhone and BlackBerry. Screen sharing supports high resolution video sharing, allowing presenters to jump to any point in the video as each participant’s screen is updated in real time. Presenters can also annotate video frames, which will likely appeal to marketing organizations.

While the service is currently working on acquiring free users, it is going to operate under a subscription model of $29 a month, or 12 cents per minute for users who would prefer to pay as they go. This is substantially cheaper than WebEx, but other less well known alternatives sport similar price points, so cost won’t be the only thing Fuze can rely on to differentiate itself.

If you’d like to see a video of the service in action, check out the clip below. Warning: it features Moran’s kids, and may be too cute to handle.

Can anyone guess the entry codes for these door locks?

There are 10,000 possible four-digit codes, but you only have to try 24 on these keypads. The first is most likely 1986 or 1968. The second is almost certainly 1234.

Those prices are in Yuans per liter, I think. Fuel Subsidies Punish Virtue The Chinese government has recently decided to raise fuel prices by about 10%, the third increase in the past few months, following a 6-7% increase on June 1st, and a 3-5% increase in March. The stated goal is to bring the price of fuel in China closer to what the market price is. From a green point of view, this is good because subsidized fossil fuels only encourages waste, over-consumption, and the buying of vehicles that aren't fuel efficient. It also artificially reduces the competitiveness of technologies that aren't based on fossil fuels, slowing down their adop...
