[T]he 737 Max . . . violated that most ancient of aviation canons and probably violated the certification criteria of the U.S. Federal Aviation Administration. But instead of going back to the drawing board and getting the airframe hardware right . . . Boeing relied on something called the “Maneuvering Characteristics Augmentation System,” or MCAS. . . .
MCAS is certainly much less expensive than extensively modifying the airframe to accommodate the larger engines. Such an airframe modification would have meant things like longer landing gear (which might not then fit in the fuselage when retracted), more wing dihedral (upward bend), and so forth. All of those hardware changes would be horribly expensive.
What’s worse, those changes could be extensive enough to require not only that the FAA recertify the 737 but that Boeing build an entirely new aircraft. Now we’re talking real money, both for the manufacturer as well as the manufacturer’s customers.
That’s because the major selling point of the 737 Max is that it is just a 737, and any pilot who has flown other 737s can fly a 737 Max without expensive training, without recertification, without another type of rating. Airlines—Southwest is a prominent example—tend to go for one “standard” airplane. They want to have one airplane that all their pilots can fly because that makes both pilots and airplanes fungible, maximizing flexibility and minimizing costs. . . .
The flight management computer is a computer. What that means is that it’s not full of aluminum bits, cables, fuel lines, or all the other accoutrements of aviation. It’s full of lines of code. And that’s where things get dangerous.
Those lines of code were no doubt created by people at the direction of managers. Neither such coders nor their managers are as in touch with the particular culture and mores of the aviation world as much as the people who are down on the factory floor, riveting wings on, designing control yokes, and fitting landing gears. Those people have decades of institutional memory about what has worked in the past and what has not worked. Software people do not.
In the 737 Max, only one of the flight management computers is active at a time—either the pilot’s computer or the copilot’s computer. And the active computer takes inputs only from the sensors on its own side of the aircraft.
When the two computers disagree, the solution for the humans in the cockpit is to look across the control panel to see what the other instruments are saying and then sort it out. In the Boeing system, the flight management computer does not “look across” at the other instruments. It believes only the instruments on its side. It doesn’t go old-school. It’s modern. It’s software.
This means that if a particular angle-of-attack sensor goes haywire—which happens all the time in a machine that alternates from one extreme environment to another, vibrating and shaking all the way—the flight management computer just believes it.
It gets even worse. There are several other instruments that can be used to determine things like angle of attack, either directly or indirectly, such as the pitot tubes, the artificial horizons, etc. All of these things would be cross-checked by a human pilot to quickly diagnose a faulty angle-of-attack sensor.
In a pinch, a human pilot could just look out the windshield to confirm visually and directly that, no, the aircraft is not pitched up dangerously. That’s the ultimate check and should go directly to the pilot’s ultimate sovereignty. Unfortunately, the current implementation of MCAS denies that sovereignty. It denies the pilots the ability to respond to what’s before their own eyes.
Like someone with narcissistic personality disorder, MCAS gaslights the pilots. And it turns out badly for everyone. “Raise the nose, HAL.” “I’m sorry, Dave, I’m afraid I can’t do that.”
In the MCAS system, the flight management computer is blind to any other evidence that it is wrong, including what the pilot sees with his own eyes and what he does when he desperately tries to pull back on the robotic control columns that are biting him, and his passengers, to death. . . .
None of the above should have passed muster. None of the above should have passed the “OK” pencil of the most junior engineering staff, much less a DER. That’s not a big strike. That’s a political, social, economic, and technical sin.
It just so happens that, during the timeframe between the first 737 Max crash and the most recent 737 crash, I’d had the occasion to upgrade and install a brand-new digital autopilot in my own aircraft. . . .

De Blasio to Announce 10-Year Deadline to Offer Computer Science to All Students
To ensure that every child can learn the skills required to work in New York City’s fast-growing technology sector, Mayor Bill de Blasio will announce on Wednesday that within 10 years all of the city’s public schools will be required to offer computer science to all students.And if any kid tries to follow their dream of creating an app that provides a creative alternative to a city-regulated market, de Blasio will do everything in his power to crush that dream.

"There are moments when there is nothing more urgent than the defense of what has already been accomplished."
In an insightful article called "Crimes Against Humanities," about the need to prevent "science" from "invading the liberal arts," Leon Wieseltier responds to Steven Pinker's essay, "Science Is Not Your Enemy," in the New Republic (this is from last year, back when they were New Republic editors):
The question of the place of science in knowledge, and in society, and in life, is not a scientific question. Science confers no special authority, it confers no authority at all, for the attempt to answer a nonscientific question. It is not for science to say whether science belongs in morality and politics and art. Those are philosophical matters, and science is not philosophy, even if philosophy has since its beginnings been receptive to science. Nor does science confer any license to extend its categories and its methods beyond its own realms, whose contours are of course a matter of debate. The credibility of physicists and biologists and economists on the subject of the meaning of life . . . cannot be owed to their work in physics and biology and economics, however distinguished it is. The extrapolation of larger ideas about life from the procedures and the conclusions of various sciences is quite common, but it is not in itself justified; and its justification cannot be made on internally scientific grounds, at least if the intellectual situation is not to be rigged. Science does come with a worldview, but there remains the question of whether it can suffice for the entirety of a human worldview. . . .(Here's Pinker's response, followed by another response from Wieseltier.)
Rejecting the various definitions of scientism—“it is not an imperialistic drive to occupy the humanities,” it is not “reductionism,” it is not “naïve”—Pinker proposes his own characterization of scientism, which he defends as an attempt “to export to the rest of intellectual life” the two ideals that in his view are the hallmarks of science. The first of those ideals is that “the world is intelligible.” The second of those ideals is that “the acquisition of knowledge is hard.” Intelligibility and difficulty, the exclusive teachings of science? This is either ignorant or tendentious. Plato believed in the intelligibility of the world, and so did Dante, and so did Maimonides and Aquinas and Al-Farabi, and so did Poussin and Bach and Goethe and Austen and Tolstoy and Proust. They all share Pinker’s denial of the opacity of the world, of its impermeability to the mind. They all join in his desire to “explain a complex happening in terms of deeper principles.” They all concur with him that “in making sense of our world, there should be few occasions in which we are forced to concede ‘It just is’ or ‘It’s magic’ or ‘Because I said so.’”
If Pinker believes that scientific clarity is the only clarity there is, he should make the argument for such a belief. He should also acknowledge its narrowness (though within the realm of science it is very wide), and its straitening effect upon the investigation of human affairs. Instead he simply conflates scientific knowledge with knowledge as such. In his view, anybody who has studied any phenomena that are studied by science has been a scientist. It does not matter that they approached the phenomena with different methods and different vocabularies. If they were interested in the mind, then they were early versions of brain scientists. If they investigated human nature, then they were social psychologists or behavioral economists. . . . If they contributed to knowledge, then they must have been scientists, because what other type of knowledge is there? . . .
[I]t was the imperative to keep up, to be “progressive,” which led to “the disaster of postmodernism” and other unfortunate hermeneutical fashions of recent decades. More importantly, the humanities do not advance the way the sciences advance. . . . The history of science is a history of errors corrected and discarded. But the vexations of philosophy and the obsessions of literature are not retired in this way. In these fields, the forward-looking cast backward glances. The history of old art and thought fuels the production of young art and thought. Scientists no longer consult Aristotle’s scientific writings, but philosophers still consult Aristotle’s philosophical writings. The present has the power of life and death over the past. It can choose to erase vast regions of it. Tradition is what the present calls those regions of the past that it retains, that it cherishes and needs. Contrary to the progressivist caricature, tradition is not the domination of the present by the past. It is the domination of the past by the present. . . .
There are moments when there is nothing more urgent than the defense of what has already been accomplished. . . . Sometimes wisdom is conventional. The denigration of conventional wisdom is itself a convention. . . .
The technological revolution will certainly transform and benefit the humanities, as it has transformed and benefited many disciplines and vocations. But it may also mutilate and damage the humanities, as it has mutilated and damaged many disciplines and vocations. My point is only that shilling for the revolution is not what we need now. The responsibility of the intellectual toward the technologies is no longer (if it ever was) mere enthusiasm. The magnitude of the changes wrought by the new machines calls for the revival of a critical temper. Too much is at stake to make do with that cool vanguard feeling. But Pinker is . . . waxing on like everybody else about how “this is an extraordinary time” because “powerful tools have been developed” and so on. . . . With his dawn-is-breaking scientistic cheerleading, Pinker shows no trace of the skepticism whose absence he deplores in others. His sunny scientizing blurs distinctions and buries problems. If there was one thing for which the humanities, the old humanities, the wearyingly traditional humanities, could be counted on, it was to introduce us also to the darkness and prepare us also for the worst.

Auto-tuned conversations
A comic from Zach Weiner's Saturday Morning Breakfast Cereal, which is worth checking out regularly:

Bill Clinton on "our one remaining bigotry"
So we need inclusive economics. We need inclusive governance. And we have to give back to systems of cooperation which minimize the happening of big, bad things and maximize the chances that good things will flow. And we have to do it through networks. That is the business of the 21st century. We can do it. But . . . you can't do it if you refuse to talk to people that disagree with you and to work with them.
You know, Americans have come so far since, let's say, the era of Joe McCarthy. I mean, think about it. We're less racist. We're less sexist. We're less homophobic than we used to be. We only have one remaining bigotry. We don't want to be around anybody who disagrees with us. And if you look, actually residential patterns in America are changing. I mean, not just on by Congressional Districts. I mean fixed-line borders, like counties, the internal, social and political complexion of them are changing, and we also are siloing our information sources.
I read the other day that 47 percent of self-identified conservatives will only watch Fox News on television. That's good for Fox News. I mean, it's a good business model. My mother-in-law, who died a couple years ago at 91, and whom I love dearly and who lived with Hillary in our Washington home while she was secretary of state and senator, was the most liberal member of our family. She watched Fox News every day. I asked her if she was trying to give herself a heart attack. She said, "No, I'm just trying to keep my blood pumping."
But then my—but then she seriously said—she said, first of all, Bill, I need to know what they're saying so I have an answer and I need to know what they're saying in case they're right. She said, nobody's wrong all the time. It's like almost biologically impossible.
So it was really interesting to see for me—as I had time to study this in the last few years—how much we are disaggregating ourselves from people who disagree with us.
So one of the things that I hope The New Republic will do in the coming century of its life and innovation is to actually make people debate an issue instead of labeling each other. I was shocked—you know, campaigns I used to be a part of, you'd see these negative ads or positive ads. But they were usually like reasonable ads subject to fact-checking, like, "My opponent wants to vaccinate cows against mad cow disease, and I think it's a terrible waste of money." And the other one said, "No, we really should do this, because just one mad cow can make a lot of people sick."
In other words, they would hit each other over something real. This was, "My opponent voted with the president 93 percent of the time." Well, what did they vote on? Would that include all the budgets? What is it? There's all this sort of dark labeling business going on. And I think the differences are healthy, but not if they're meaningless designed to shut people's brains down instead of fire them up, because unfortunately if you want to return to the kind of broad-based prosperity we had in the 1990s, it will require some really clever thought.
For example, I was blessed because the information technology revolution moved out of Silicon Valley, and the exchange companies here in northern Virginia, and the videogame companies in Texas, and Route 28, and it went into every aspect of the American economy. So all I had to do was put the pedal to the metal and try to figure out how to get it to places and people that would otherwise be left out and left behind. And it was 8 percent of our employment, 20 percent of our job growth, 33 percent of our wage growth, guaranteeing broad-based prosperity. The bottom 20 percent of our workforce's income grew as much as the top 5 percent, the only time in more than 40 years. A hundred times as many people moved out of poverty into the middle class as during the Reagan presidency, which was the high point of trickle-down economics.
Now there are people who say, if you look at Uber, Airbnb, all the fun stuff, that now we're on the 100 percent downside of that and all these technological innovations are by definition using less labor and not starting enough economic activity in some other place to generate more jobs. I don't believe that, by the way, because we're still a couple million jobs or more we could be generating in America on the energy revolution, which would in turn create a lot of other jobs, and because the biotechnology revolution is just getting underway, and because there are four or five categories in which there will be more jobs created in health care, even if we continue to implement the law and we continue to lower the price of it relative to our competitors.
But this is the first thing we have to do. We have got to focus on having an economy where prosperity is more broadly shared. And we have to think about it for the rest of the world, too, because a lot of the appeal of a lot of these groups comes to young, angry people who don't have anything to do when they get up in the morning and don't have anything to look forward to and think, unless they go pick up a rifle or a bomb, every tomorrow will be just like yesterday.
When I was born at the end of World War II, more than half The New Republic's life ago—alas, way more than half—my native state's income was 56 percent, I think, of the national average, the second poorest state in the country. But if you could put clothes on your back and food on the table and feed a neighbor who walked up unannounced, nobody really thought they were poor. And it was relatively rare to see somebody who had nothing to do and no way to earn any money.
When I was in law school, I had six jobs, never more than three at once. I never felt burdened or put upon, because I always knew that I could do something. I became a lawyer because I wanted a job where nobody could ever force me to retire. I wanted to die with my boots on. . . .
But the point is there was this sense of possibility in our country. So we had to do the civil rights revolution, because we were cutting too many people out of it, but once we did that, there was a sense of possibility. We have got to recover that. And we have to understand, in my opinion, that immigration reform is a part of that.
Having lost it, I can tell you: Youth matters. The youth of a workforce matters. One of the problems is, according to Fareed Zakaria's show last Sunday, Americans think 31 percent of our population are immigrants. And in fact, it's about 12 percent or 13 percent.
But I really was almost physically ill at the—what some people say when all those Central American immigrants showed up at the border. I don't even know if everybody here knows this, but there had been zero net in-migration from Mexico in the last four years. Zero net in-migration from Mexico, partly because the previous president, Mr. Calderon, established 140 tuition-free universities. And last year, Mexico, barely a third our population, graduated 113,000 engineers, the United States 120,000. They're in the innovation business. All you got to do is go to Mexico City now and look around. . . .
George W. Bush signed a bipartisan bill saying that if somebody showed up on our border and they felt they were at risk, they had a right to a hearing. It was a good and decent thing. It's fine if the administration is trying to protect people where they live so they can process there and they're not all lined up on the border, but to think that this means, oh, the border's out of control, the world's coming to an end, we don't need immigration reform, it's wrong. Those people will make America's future.
Do we have to have fair rules? Do we have to make people wait in line, do you not want people jumping? Yeah, all of that's true. But the more prosperous our neighbors get, the less illegal immigration we'll have and the more we'll want people to come here and, if they get an education, to stay here, particularly, and contribute to us. So I'm looking forward to what will be said tomorrow. . . .
The New Republic can affect that, not by pretending there's only one side of the story, but making sure people at least know what's going on. We've got—if you want to have inclusive governance, there has to be a conversation that has some rough relationship to the facts. And I don't mean just the facts that are useful in a political debate. Everybody in a busy life has to be careful not to become vulnerable to the storyline and have it then turn out to be inconsistent with the story.
But I'm just telling you, you should not be pessimistic about America. And you should not be pessimistic about the world. These guys are not going to win over the long run in the Middle East with the strategy of decapitating everybody that disagrees with them. The local people (inaudible) now, the Kurds are fighting back. It may be a long, hard fight, so nobody wants to live that way. They are recruiting by and large who are looking for a quick trip to Heaven because they think all those tomorrows on Earth are going to be just like yesterday.

Why have we stopped being optimistic about the future?
I sympathize with science-fiction writer Neal Stephenson and venture-capitalist Peter Thiel, whose new books lament the demise of grand 20th-century dreams and the optimistic culture they expressed. “I worry that our inability to match the achievements of the 1960s space program might be symptomatic of a general failure of our society to get big things done,” writes Stephenson in the preface to "Hieroglyph," a science-fiction anthology hoping “to rekindle grand technological ambitions through the power of storytelling.” ...
[W]e have plenty of big projects. The human genome has been sequenced. Enormous libraries of books and collections of paintings and drawings have been scanned and made searchable online. James Turrell is making great monumental art in the Arizona desert. Three -- three! -- billionaires are running their own space programs. Space is so popular among his peers that Bill Gates, whose own modest goals run to conquering malaria and other tropical scourges, finds himself telling interviewers that “it’s not an area that I’ll be putting money into.” If there’s public malaise about progress, it isn’t because nobody is doing anything bold....
The reason mid-20th-century Americans were optimistic about the future wasn’t that science-fiction writers told cool stories about space travel. Science-fiction glamour in fact worked on only a small slice of the public.... People believed the future would be better than the present because they believed the present was better than the past. They constantly heard stories -- not speculative, futuristic stories but news stories, fashion stories, real-estate stories, medical stories -- that reinforced this belief. They remembered epidemics and rejoiced in vaccines and wonder drugs. They looked back on crowded urban walk-ups and appreciated neat suburban homes. They recalled ironing on sweaty summer days and celebrated air conditioning and wash-and-wear fabrics. They marveled at tiny transistor radios and dreamed of going on airplane trips.
Then the stories changed. For good reasons and bad, more and more Americans stopped believing in what they had once viewed as progress. Plastics became a punch line, convenience foods ridiculous, nature the standard [warning: New York Times link] of all things right and good. Freeways destroyed neighborhoods. Urban renewal replaced them with forbidding Brutalist plazas. New subdivisions represented a threat to the landscape rather than the promise of the good life. Too-fast airplanes produced window-rattling sonic booms [NYT link]. Insecticides harmed eagles’ eggs. Exploration meant conquest and brutal exploitation. Little by little, the number of modern offenses grew until we found ourselves in a 21st century where some of the most educated, affluent and culturally influential people in the country are terrified of vaccinating their children. Nothing good, they’ve come to think, comes from disturbing nature.

Are "smart" gadgets going to take over our lives?
In an article called "Is Smart Making Us Dumb?" (or, in the more comprehensible heading at the top of the browser window, "Are Smart Gadgets Making Us Dumb?"), Evgeny Morozov writes this in the Wall Street Journal:
A revolution in technology is allowing previously inanimate objects—from cars to trash cans to teapots—to talk back to us and even guide our behavior. But how much control are we willing to give up? ...
BinCam looks just like your average trash bin, but with a twist: Its upper lid is equipped with a smartphone that snaps a photo every time the lid is shut. The photo is then uploaded to Mechanical Turk, the Amazon-run service that lets freelancers perform laborious tasks for money. In this case, they analyze the photo and decide if your recycling habits conform with the gospel of green living. Eventually, the photo appears on your Facebook page.
You are also assigned points, as in a game, based on how well you are meeting the recycling challenge. The household that earns the most points "wins." In the words of its young techie creators, BinCam is designed "to increase individuals' awareness of their food waste and recycling behavior," in the hope of changing their habits.
BinCam has been made possible by the convergence of two trends that will profoundly reshape the world around us. First, thanks to the proliferation of cheap, powerful sensors, the most commonplace objects can finally understand what we do with them—from umbrellas that know it's going to rain to shoes that know they're wearing out—and alert us to potential problems and programmed priorities. These objects are no longer just dumb, passive matter. With some help from crowdsourcing or artificial intelligence, they can be taught to distinguish between responsible and irresponsible behavior (between recycling and throwing stuff away, for example) and then punish or reward us accordingly—in real time. ...
In 2010, Google Chief Financial Officer Patrick Pichette told an Australian news program that his company "is really an engineering company, with all these computer scientists that see the world as a completely broken place." Just last week in Singapore, he restated Google's notion that the world is a "broken" place whose problems, from traffic jams to inconvenient shopping experiences to excessive energy use, can be solved by technology. The futurist and game designer Jane McGonigal, a favorite of the TED crowd, also likes to talk about how "reality is broken" but can be fixed by making the real world more like a videogame, with points for doing good. From smart cars to smart glasses, "smart" is Silicon Valley's shorthand for transforming present-day social reality and the hapless souls who inhabit it.
But there is reason to worry about this approaching revolution. As smart technologies become more intrusive, they risk undermining our autonomy by suppressing behaviors that someone somewhere has deemed undesirable. Smart forks inform us that we are eating too fast. Smart toothbrushes urge us to spend more time brushing our teeth. Smart sensors in our cars can tell if we drive too fast or brake too suddenly.
These devices can give us useful feedback, but they can also share everything they know about our habits with institutions whose interests are not identical with our own. Insurance companies already offer significant discounts to drivers who agree to install smart sensors in order to monitor their driving habits. How long will it be before customers can't get auto insurance without surrendering to such surveillance? And how long will it be before the self-tracking of our health (weight, diet, steps taken in a day) graduates from being a recreational novelty to a virtual requirement? ...
To grasp the intellectual poverty that awaits us in a smart world, look no further than recent blueprints for a "smart kitchen"—an odd but persistent goal of today's computer scientists, most recently in designs from the University of Washington and Kyoto Sangyo University in Japan.
Once we step into this magic space, we are surrounded by video cameras that recognize whatever ingredients we hold in our hands. Tiny countertop robots inform us that, say, arugula doesn't go with boiled carrots or that lemon grass tastes awful with chocolate milk. This kitchen might be smart, but it's also a place where every mistake, every deviation from the master plan, is frowned upon. It's a world that looks more like a Taylorist factory than a place for culinary innovation. Rest assured that lasagna and sushi weren't invented by a committee armed with formulas or with "big data" about recent consumer wants.
Creative experimentation propels our culture forward. That our stories of innovation tend to glorify the breakthroughs and edit out all the experimental mistakes doesn't mean that mistakes play a trivial role. As any artist or scientist knows, without some protected, even sacred space for mistakes, innovation would cease.

Why does Obama think ATMs take jobs away from bank tellers?
President Obama said in his recent speech in Kansas:
Over the last few decades, huge advances in technology have allowed businesses to do more with less, and made it easier for them to set up shop and hire workers anywhere in the world. And many of you know firsthand the painful disruptions this has caused for a lot of Americans. . . .If you're going to make such a stark claim and phrase it in pragmatic terms of what has "worked," you should at least make sure the facts are on your side with respect to your own specific examples. But Matthew Yglesias disproves Obama's claim about ATMs replacing bank tellers with one simple chart (from this site):
If you were a bank teller or a phone operator or a travel agent, you saw many in your profession replaced by ATMs or the internet. Today, even higher-skilled jobs like accountants and middle management can be outsourced to countries like China and India. And if you’re someone whose job can be done cheaper by a computer or someone in another country, you don’t have a lot of leverage with your employer when it comes to asking for better wages and benefits — especially since fewer Americans today are part of a union.
Now, . . . there’s been a certain crowd in Washington for the last few decades who respond to this economic challenge with the same old tune. “The market will take care of everything,” they tell us. If only we cut more regulations and cut more taxes — especially for the wealthy – our economy will grow stronger. Sure, there will be winners and losers. But if the winners do really well, jobs and prosperity will eventually trickle down to everyone else. . . .
It’s a simple theory – one that speaks to our rugged individualism and healthy skepticism of too much government. It fits well on a bumper sticker. Here’s the problem: It doesn’t work. It’s never worked.
Yglesias explains:
[I]t's true that since the recession started, we've seen fewer people on the job as tellers. But that's not a decades-long technologically induced trend. It's a recession. The [U.S. Bureau of Labor Statistics] continues to project long-term growth in the number of bank tellers presumably because banks like to open branches to attract deposits. It's true that bank tellers as a share of the labor force should shrink but that's different. Banks are doing more with a little bit more, not doing more with less.Of course, one question is: why didn't Obama have anyone fact-check his speech? But more importantly, this shows Obama's attachment to left-wing ideology. He has faith that technological progress destroys jobs. If you're strongly inclined to see advances in technology as setbacks to society, then it's easy to believe that the idea of an efficient free market doesn't make sense.

Do you "love your iPhone"?
"Literally"?
Or, is an article that says modern technology is disconnecting us from human interaction, and claims to back this up with a brain imaging study, too good for the New York Times to check?

The inventor of the eBook and founder of Project Gutenberg, Michael S. Hart, dies at 64.
Project Gutenberg reports (via):
Hart was best known for his 1971 invention of electronic books, or eBooks. He founded Project Gutenberg, which is recognized as one of the earliest and longest-lasting online literary projects. He often told this story of how he had the idea for eBooks. He had been granted access to significant computing power at the University of Illinois at Urbana-Champaign. On July 4 1971, after being inspired by a free printed copy of the U.S. Declaration of Independence, he decided to type the text into a computer, and to transmit it to other users on the computer network. From this beginning, the digitization and distribution of literature was to be Hart's life's work, spanning over 40 years.
Hart was an ardent technologist and futurist. A lifetime tinkerer, he acquired hands-on expertise with the technologies of the day: radio, hi-fi stereo, video equipment, and of course computers. He constantly looked into the future, to anticipate technological advances. One of his favorite speculations was that someday, everyone would be able to have their own copy of the Project Gutenberg collection or whatever subset desired. This vision came true, thanks to the advent of large inexpensive computer disk drives, and to the ubiquity of portable mobile devices, such as cell phones.
Hart also predicted the enhancement of automatic translation, which would provide all of the world's literature in over a hundred languages. While this goal has not yet been reached, by the time of his death Project Gutenberg hosted eBooks in 60 different languages, and was frequently highlighted as one of the best Internet-based resources.
A lifetime intellectual, Hart was inspired by his parents, both professors at the University of Illinois, to seek truth and to question authority. One of his favorite recent quotes, credited to George Bernard Shaw, is characteristic of his approach to life:
"Reasonable people adapt themselves to the world. Unreasonable people attempt to adapt the world to themselves. All progress, therefore, depends on unreasonable people." . . .
The invention of eBooks was not simply a technological innovation or precursor to the modern information environment. A more correct understanding is that eBooks are an efficient and effective way of unlimited free distribution of literature. Access to eBooks can thus provide opportunity for increased literacy. Literacy, and the ideas contained in literature, creates opportunity.
In July 2011, Michael wrote these words, which summarize his goals and his lasting legacy: “One thing about eBooks that most people haven't thought much is that eBooks are the very first thing that we're all able to have as much as we want other than air. Think about that for a moment and you realize we are in the right job." He had this advice for those seeking to make literature available to all people, especially children:
"Learning is its own reward. Nothing I can say is better than that."

Do smartphone patents inhibit innovation?
In a recent blog post, David Drummond, Google’s chief legal officer, wrote that a modern smartphone might be susceptible to as many as 250,000 potential patent claims, depending on how broadly those patents and claims were interpreted.In addition to all that complexity, randomness, and waste, patent law shifts money around in ways that appear unrelated or even opposed to innovation:
“The trouble is that in this industry so often a patent is not a clearly defined property right, but a lottery ticket of uncertain value,” said Scott Stern, a professor at the Sloan School of Management at the Massachusetts Institute of Technology. “That uncertainty can carry a lot of risk and cost.”
This patent gold rush . . . is diverting money for innovation from industries crucial to the economic future of the United States, analysts say. Patents were created as an incentive for innovation, giving inventors a temporary right to commercialize their ideas, without others copying them. While the recent blockbuster patent deals may make sense for the companies, analysts say, they are fed largely by legal considerations — asserting patent claims or defending against claims — rather than economic ones.
So the very innovation patents were intended to encourage, they say, suffers in the patent wars. “You’d much rather see Apple spend some of that $4 billion on new inventions, and Google invest that $12 billion to generate new knowledge,” said Josh Lerner, an economist at the Harvard Business School. “It’s a transfer of wealth from innovators to bondholders and stockholders who have no motivation to innovate. It’s disturbing.”So, when these observations make for a good article, the New York Times is willing to point out how a government policy can have unintended consequences that are contrary to the policy's original purpose. Patent law is only one of many examples of how this can happen; the economist Thomas Sowell has practically based a career on calling out such policies. I hope the New York Times editorial page writers are keeping this lesson in mind too, instead of just assuming that wherever the free market fails to work perfectly, legislation or regulation can make it better.

Are holograms the future of "live" music?
A hologram of Hatsune Miku — a fictional character from a computer application — performs in Japan for a crowd of glowingly enthusiastic fans:
She's been giving concerts since last year.
I saw this when P____ posted it to Facebook. P____ says:
I can't see why it won't start happening everywhere. A Lady Gaga hologram could play 100 shows across the country on the same night.

Computers are wonderful and horrible - the view from 1982
Here's another gem from the Atlantic's project of digging up old technology articles from its archives: a 1982 article by James Fallows (who still writes for the magazine) called "Living with a Computer."
The Atlantic's blog post about the article points out how obsolete the references to companies are now, as they've since been the victim of creative destruction:
Nearly all the companies building system components that Fallows mentioned are gone or bit players now: Optek, Ball Corporation . . . , Lanier, Wang, Digital Research, Heath-Zenith, Victor. As Fallows noted, it was like the automobile industry of 1910, "a thousand little hustlers trying to claim a piece of the action." Neither Apple nor Microsoft made it onto his radar.I find it fascinating to read Fallows describing his encounters with a machine we use all the time without thinking about it, back when this was such a novel experience that it merited a lengthy essay in the Atlantic. I'm tempted to copy and paste the whole article into this blog post, but that would be inappropriate. Here's the gist of it:
I'd sell my computer before I'd sell my children. But the kids better watch their step. When have the children helped me meet a deadline? When has the computer dragged in a dead cat it found in the back yard?I think he's basically right, and if anything he's understating how much of a boon computers have been to the writing and editing process. They don't make writing quicker at the expense of quality; they improve the quality by allowing you to write and edit more quickly.
The Processor Technology SOL-20 came into my life when Darlene went out. It was a bleak, frigid day in January of 1979, and I was finishing a long article for this magazine. The final draft ran for 100 pages, double-spaced. Interminable as it may have seemed to those who read it, it seemed far longer to me, for through the various stages of composition I had typed the whole thing nine or ten times. My system of writing was to type my way through successive drafts until their ungainliness quotient declined. This consumed much paper and time. In the case of that article, it consumed so much time that, as the deadline day drew near, I knew I had no chance of retyping a legible copy to send to the home office.
I turned hopefully to the services sector of our economy. I picked a temporary-secretary agency out of the phone book and was greeted the next morning by a gum-chewing young woman named Darlene. I escorted her to my basement office and explained the challenge. The manuscript had to leave my house by 6:30 the following evening. No sweat, I thought, now that a professional is on hand.
But five hours after Darlene's arrival, I glanced at the product of her efforts. Stacked in a neat pile next to the typewriter were eight completed pages. This worked out to a typing rate of about six and a half words per minute. In fairness to Darlene, she had come to a near-total halt on first encountering the word "Brzezinski" and never fully regained her stride. Still, at this pace Darlene and I would both be dead—first I'd kill her, then I'd kill myself—before she came close to finishing the piece. Hustling her out the door at the end of the day, with $49 in wages in her pocket and eleven pages of finished manuscript left behind, I trudged downstairs to face the typewriter myself. Twenty-four hours later, I handed the bulky parcel to the Federal Express man and said, "Never again."
Over the next few weeks, my thoughts often drifted to the advertisements I had seen in airline magazines, in which trim and cheerful secretaries effortlessly produced documents by typing in front of computer screens. Were these devices real? I checked with a salesman for a company called Lanier and discovered that while their word-processing system, called "No Problem," was quite real, it cost some $15,000. If I had drawn a pie chart representing my annual income, No Problem would have been a very large piece of pie. I called Wang, Digital Equipment, and some of the other big-name manufacturers and got roughly the same news. If I called the same manufacturers today, I'd hear much more encouraging news, but my options were to start writing shorter articles, go into hock, or take my chances again with Darlene.
The way out of my dilemma came from an unexpected quarter. My father-in-law often dealt with inventors who put together computer systems to monitor various industrial processes, and he thought that one of them might have the answer. On his advice, I followed a trail of leads and suggestions that eventually led me to a converted church in the farmlands of central Ohio. There, Bill Cavage, Marv Monroe, and Bill Jones, three young engineers doing business as the Optek Corporation, tinkered with disk drives, photo-sensors, and other devices in hopes of making the big sale. Optek's specialty is making machines like the one they produce for drug companies, which counts pills as they pass by at a rate of 24,000 per minute and kicks out any bottles that receive the wrong number of pills. For men who can do all this, I thought, turning a small computer into a word-processing system should be a cinch.
For a while, I was a little worried about what they would come up with, especially after my father-in-law called to ask how important it was that I be able to use both upper- and lower-case letters. But finally, for a total of about $4,000, Optek gave me the machinery I have used happily to this day.
The ingredients were the basic four of any word-processing system. First was the computer itself, the Processor Technology SOL-20. Its detailed specifications—its 48K of random access memory, its Intel 8080 microprocessing chip—are now of antiquarian interest, since Processor Technology went out of business several months after I bought my computer.
The second element in my system was the monitor, a twelve-inch TV screen. Some monitors are like black-and-white TVs; mine—which, oddly enough, was produced by the same company, Ball Corporation, that makes home-canning supplies, displays light-green letters against a background of dark green and is supposed to be easier on the eyes. Third was the external storage device—the equipment that saves the documents you've written when the computer is turned off. The equipment I chose, two small tape recorders, was such a complete disaster that I must discuss it separately later on. Fourth was the printer, a ponderous machine, built like a battleship, which had been an IBM Selectric typewriter before it was converted to accept printing instructions from a computer.
These four machines, and the yards and yards of multi-strand cable that connected them, were the hardware of my system. The software consisted of a program called The Electric Pencil, with a manual explaining the mysteries of "block move," "home cursor," and "global search and replace."
I skip past the day during which I thought the computer didn't work at all (missing fuse) and the week or two it took me to understand all the moves The Electric Pencil could make. From that point on, I knew there was a heaven.
What was so exciting? Merely the elimination of all drudgery, except for the fundamental drudgery of figuring out what to say, from the business of writing. The process works this way.
When I sit down to write a letter or start the first draft of an article, I simply type on the keyboard and the words appear on the screen. For six months, I found it awkward to compose first drafts on the computer. Now I can hardly do it any other way. It is faster to type this way than with a normal typewriter, because you don't need to stop at the end of the line for a carriage return (the computer automatically "wraps" the words onto the next line when you reach the right-hand margin), and you never come to the end of the page, because the material on the screen keeps sliding up to make room for each new line. It is also more satisfying to the soul, because each maimed and misconceived passage can be made to vanish instantly, by the word or by the paragraph, leaving a pristine green field on which to make the next attempt.
My computer has a 48K memory. Since each K represents 1,024 bytes of information—each byte representing one character or digit—the machine can manipulate more than 49,000 items of information at a time. In practice, after allowing for the space that The Electric Pencil's programming instructions occupy in the computer's memory, the machine can handle documents 6,500 to 7,500 words long, or a little longer than this article. I break anything longer into chunks or chapters and work with them one at a time.
When I've finished with such a chunk, I press another series of buttons and store what I have written on my disk drive. This is a cigar-box-shaped unit that sits next to my computer, connected through a shocking-pink ribbon cable containing thirty-four separate strands. Inside the drive is the floppy disk, which is essentially magnetic recording tape pressed into the shape of a small record and then enclosed in a square cardboard envelope, 5 1/4 inches on each side. The system transfers data from the computer to the disk, or vice versa, at about 1,000 words per second, so it is no nuisance to pause after each fifteen or twenty minutes of writing to store what I've just done. Each of the disks in my system can hold about 100K of information, or more than twice as much as a full load from the computer memory. If one disk is full, I pull it out and snap another in.
When I finish what I'm working on, I switch on my printer. If I'm sending a letter, I load the stationery into the printer and push the print button, and then fish each piece of paper out of the printer when it is done. There are machines that automatically feed single sheets of paper into the printer, but that takes us back to big slices of the income pie. If I am printing a draft of an article, I can hook up my tractor feed, push the print button, and go out for a beer. The tractor pulls an endless sheet of paper through the printer—and the perforated paper can be separated into pages when the printing is done, so it looks like a normal manuscript.
The system prints about thirty characters per second, which means it takes less than a minute per double-spaced page. When it has completed its work, I take the manuscript and start working it over with a pencil, just as I did in days of old. The difference is that after I've made my changes, I have only to type in the changes I have made and start the printer up again—rather than retype the whole mess.
None of this may sound impressive to those who have fleets of secretaries at their disposal, or to writers who can say precisely what they mean the first time through. Isaac Asimov recently complained in Popular Computing that his word-processor didn't save him much time on revisions, since he composes at ninety words per minute and "95 per cent of what I write in the first draft stays in the second [and final] draft." My first-draft survival ratio is closer to one percent, so for me the age of painless revisions is a marvel.
You won't catch me saying that my machine has made me a better writer, but I don't think it has made me any worse. Since I now spend less time and energy retyping, I have more left over for editing and rewriting.
He then describes a strange way to use technology to improve editing, which I had never heard of:
When I think I'm finished with an article, I set the print speed to Slow. This runs the printer at about 100 words per minute, or roughly the pace of reading aloud. I stuff my ears with earplugs and then lean over the platen as the printing begins. Watching the article printed at this speed is like hearing it read; infelicities are more difficult to ignore than when you are scooting your eye over words on a page.More:
I have not yet stooped to the politician's trick of programming the computer to write standard letters of reply. I have, however, discovered a few other sneaky word-processing feats. Suppose you are writing an article in which an unusual word appears frequently—let us choose "Brzezinski" once again. When writing the draft, you simply type a certain character, say * or + , each time Brzezinski should appear, and then when you're ready to print you signal the computer to insert "Brzezinski" in place of the character.Imagine thinking that this keyboard shortcut was so devious it was worth mentioning in the same breath as having an artificial-intelligence ghostwriter!
He also used a precursor to TurboTax:
In addition to The Electric Pencil, I bought the software for a computer-programming language known as BASIC . . . . When I want to know how many prime numbers there are between one million and two million, or how quickly my mortgage payments would bankrupt me if interest rates rose to 35 percent—that is, when I don't want to do my work—I can kill ten minutes writing programs to tell me the answer. Getting down to business, I use the computer to do my income tax. My economic life is a mess of $2.75 parking-lot tickets and $13.89 lunch receipts, which used to pile up like fall leaves until I spent a week burrowing through them at income-tax time. Now all I do is sit down at the machine for five minutes every few nights and type in all transactions of interest to the tax man—so much in from my employers, so much out to the credit-card company. At the end of the year, I load the income-tax program into the computer, push the button marked "Run," and watch as my tax return is prepared. Since it took me only about six months to learn BASIC (and the tax laws) well enough to write the program, I figure this approach will save me time by 1993.Fallows goes on to discuss a long litany of technical issues that are now happily irrelevant to us. Should you use tapes or disks to store your information? If you use disks, should they be 5 1/2 or 8 inches in diameter? And should they have "single-density" or "double-density storage"? Fallows reports that he bought two 5 1/2-inch disks, but was frustrated that "each disk fills up too quickly and I have to keep rotating different disks in and out of the drive."
He admits that his computer has caused serious problems:
For one, it creates yet another reason to feel vulnerable to the workings of fate.He ends by telling us of his shockingly modest hope "for a world in which my sons can grow up to have a better computer than their father had." Uh, yeah!
Shortly after I got my machine, I was typing away in the basement as a summer thunderstorm moved into town. Knowing what I now know, these days I immediately shut off the machine and unplug it from the wall whenever thunder is reported any nearer than West Virginia. But I was not so wise then. I had turned on the printer and gone upstairs when a bolt of lightning struck the house. There was a huge boom, and a white flash outside windows on all sides of our house. Several million volts coursed through our wiring and blew out nearly every electrical appliance that was plugged in. The blast burned out a clothes iron, and if it had that effect on a big hunk of steel, you can imagine what went on in the computer's delicate interior. For a month I was machine-less, thrown back on my Smith-Corona, while computer repairmen replaced one silicon chip after another that had melted in its casing.
Computers cause another, more insidious problem, by forever distorting your sense of time. When I first saw the system in the back room at Optek, I was so dazzled by the instantaneous deletion of sentences and movement of paragraphs that I thought I could never want anything more. When the scientists at Optek warned me about certain bottlenecks, I had to stifle my laughter. In particular, they warned me that I might grow impatient with tape recorders as a way to store data. You have to understand, they told me, it can take five or ten minutes to load a long draft into the computer from tapes, whereas a disk drive (which would add a thousand dollars to the cost) could do the job in seconds. Typical vulgarians of the machine age, I told myself. How could they imagine that I would object to five or ten minutes, when I had been spared Darlene?
Three weeks later, I was griping constantly about the tapes and scanning the pages of Byte magazine, looking for a good deal on a disk drive. Ten minutes was intolerable when everything else happened in a flash. Worse, the tapes had the fatal defect of unreliability; even after waiting ten minutes, you were never quite sure that the information was safely stored. The only way to tell was to try to feed the data back from the tapes into the computer, which took another ten minutes and often led to the infuriating message "Tape Error." After one article disappeared forever behind a thicket of Tape Errors, I scraped up $800 for a cut-rate disk drive. Now my discontent is awakened only when I read stories about the new disks—larger ones that hold twice as much data as mine, and double-density models that hold twice as much as that.
I CAN HARDLY BRING myself to mention the true disadvantage of computers, which is that I have become hopelessly addicted to them. To the outside world, I present myself as a man with a business need for a word-processing machine. Sure, I have a computer: I'd have a drill press if I were in the machine-tool business. This is the argument I make frequently to my wife. The truth, which she has no doubt guessed, is that I love to see them work.
I nearly destroyed my health, to say nothing of my marriage, during the months when I switched off The Electric Pencil at ten or eleven at night-and then switched on BASIC and spent a few hours refining a tax-and-accounting system. At first my goal was merely to design a program that would work, that wouldn't print "Syntax Error in Line 2140" when I tried to run it. Then I started playing around, seeing if I could work out a scheme for financial projections that would take care of estimated tax payments to the IRS. Would it have been easier to mail in the $150 each quarter and then square accounts with the IRS at the end of the year? Of course—but that was not the point. Eventually, I aspired even to elegant programming, designing the matrices and the nested loops in a way that added the beauty of simplicity to the scheme.
When I contemplate my future with computers, my emotions are mixed. Because time and progress have passed my machine by, I simply can't buy any new programs for the SOL. They don't exist. This is a source of unending frustration: how I'd love to use a new word-processing program, one that could insert footnotes at the bottom of the proper page or automatically prepare an index for a book. How I'd love to get VisiCalc or SuperCalc or one of the other accounting systems that can turn a home computer into a miniature version of the National Bureau of Economic Research. How deprived I feel as I read the fliers for CompuServe and The Source, the over-the-phone services that enable you to make airline reservations, call up old newspaper articles, and send computer mail, all from the privacy of your home. How I wish my employers would install computers in their headquarters, so I could submit articles over the telephone, one computer to another, instead of fighting the crowds at the Express Mail window.
Yet even as I think these thoughts, I fear their fulfillment. My computer already competes with wife and children for my affection: can our family stand anything more? The question will remain moot until the price of replacement computers comes down a little more—or until I succeed in convincing my wife that she, too, needs a computer, so I can give her mine and rush out to buy a new one for myself (for business purposes, of course).

Photography is amazing - the view from 1859
A writer for the Atlantic is rummaging through the magazine's archives of old articles about then-emerging technologies (via).
Here is Oliver Wendell Holmes, Sr. (father of Supreme Court Justice Oliver Wendell Holmes, Jr.), writing in 1859 about photography (I've corrected a few errors in the Atlantic's text scans without indicating this):
This triumph of human ingenuity is the most audacious, remote, improbable, incredible,—the one that would seem least likely to be regained, if all traces of it were lost, of all the discoveries man has made. It has become such an everyday matter with us, that we forget its miraculous nature, as we forget that of the sun itself, to which we owe the creations of our new art. Yet in all the prophecies of dreaming enthusiasts, in all the random guesses of the future conquests over matter, we do not remember any prediction of such an inconceivable wonder, as our neighbor round the corner, or the proprietor of the small house on wheels, standing on the village common, will furnish any of us for the most painfully slender remuneration. No Century of Inventions includes this among its possibilities. Nothing but the vision of a Laputan, who passed his days in extracting sunbeams out of cucumbers, could have reached such a height of delirium as to rave about the time when a man should paint his miniature by looking at a blank tablet, and a multitudinous wilderness of forest foliage or an endless Babel of roofs and spires stamp itself, in a moment, so faithfully and so minutely, that one may creep over the surface of the picture with his microscope and find every leaf perfect, or read the letters of distant signs, and see what was the play at the "Variétés" or the "Victoria," on the evening of the day when it was taken, just as he would sweep the real view with a spy-glass to explore all that it contains. . . .He also goes into great detail about the physical process of photography. Here's an excerpt of his much longer description of the photographic negative:
We were just now stereographed, ourselves, at a moment's warning, as if we were fugitives from justice. A skeleton shape, of about a man's height, its head covered with a black veil, glided across the floor, faced us, lifted its veil, and took a preliminary look. When we had grown sufficiently rigid in our attitude of studied ease, and got our umbrella into a position of thoughtful carelessness, and put our features with much effort into an unconstrained aspect of cheerfulness tempered with dignity, of manly firmness blended with womanly sensibility, of courtesy, as much as to imply,—"You honor me, Sir," toned or sized, as one may say, with something of the self-assertion of a human soul which reflects proudly, "I am superior to all this,"—when, I say, we were all right, the spectral Mokanna dropped his long veil, and his waiting-slave put a sensitive tablet under its folds. The veil was then again lifted, and the two great glassy eyes stared at us once more for some thirty seconds. The veil then dropped again; but in the mean time, the shrouded sorcerer had stolen our double image; we were immortal.
[T]he picture is reversed, just as in every camera-obscura where the image is received on a screen direct from the lens. Thus the glass plate has the right part of the object on the left side of its picture, and the left part on its right side; its light is darkness, and its darkness is light. Everything is just as wrong as it can be, except that the relations of each wrong to the other wrongs are like the relations of the corresponding rights to each other in the original natural image. This is a negative picture.His next thought verges on science fiction:
Extremes meet. Every given point of the picture is as far from truth as a lie can be. But in travelling away from the pattern it has gone round a complete circle, and is at once as remote from Nature and as near it as possible. . . .
Out of the perverse and totally depraved negative,—where it might almost seem as if some magic and diabolic power had wrenched all things from their proprieties, where the light of the eye was darkness, and the deepest blackness was gilded with the brightest glare,—is to come the true end of all this series of operations, a copy of Nature in all her sweet gradations and harmonies and contrasts.
[P]erhaps this world is only the negative of that better one in which lights will be turned to shadows and shadows into light, but all harmonized, so that we shall see why these ugly patches, these misplaced gleams and blots, were wrought into the temporary arrangements of our planetary life.

Suicide and gay shaming through online privacy invasion at Rutgers University
A search for [Rutgers suicide] — not on the whole web, but restricted to blog posts only in the past 24 hours — returns over 8,500 results right now. The same story is also on the front page of Memeorandum, a website that automatically generates a list of the top news stories being covered by both traditional journalists and bloggers.
This is the story that's getting so much attention:
The death of a Rutgers University freshman stirred outrage and remorse on campus from classmates who wished they could have stopped the teen from jumping off a bridge last week after a recording of him having a sexual encounter with a man was broadcast online. . . .Whether or not Ravi and Wei end up receiving any criminal punishment, they've already been punished in the media: the New York Times is prominently displaying yearbook-style headshots of them.
A lawyer for [Tyler] Clementi's family confirmed Wednesday that he had jumped off the George Washington Bridge last week. Police recovered a man's body Wednesday afternoon in the Hudson River just north of the bridge, and authorities were trying to determine if it was Clementi's.
Clementi's roommate, Dhraun Ravi, and fellow Rutgers freshman Molly Wei, both 18, have been charged with invading Clementi's privacy. Middlesex County prosecutors say the pair used a webcam to surreptitiously transmit a live image of Clementi having sex on Sept. 19 and that Ravi tried to webcast a second encounter on Sept. 21, the day before Clementi's suicide. . . .
Collecting or viewing sexual images without consent is a fourth-degree crime. Transmitting them is a third-degree crime with a maximum prison term of five years.
The Times reports:
Rutgers officials would not say whether the two suspects had been suspended. But in a statement late Wednesday, the university’s president, Richard L. McCormick, said, “If the charges are true, these actions gravely violate the university’s standards of decency and humanity.”More details of what happened:
Ravi's Twitter feed on [September 19] referred to seeing his roommate have sex with another man in their room on the Piscataway campus, classmates said.Clementi wrote this on September 22 as a status update on Facebook:
"Roommate asked for the room till midnight. I went into molly's room and turned on my webcam. I saw him making out with a dude. Yay," Ravi said on his Twitter page in a Sept. 19 entry posted at 6:17 p.m.
Two days later, Ravi posted another entry directing his nearly 150 Twitter followers to iChat, an internet messaging service with a live video feed.
"Anyone with iChat, I dare you to video chat me between the hours of 9:30 and 12. Yes it's happening again," Ravi wrote in the Sept. 21 post.
Ravi's Twitter feed has since been taken down. But the entries survived in a cached version of the page still available through Google's search engine this afternoon. . . .
Prosecutors said Ravi and Wei set up a camera on Sept. 19 and broadcast live images of Clementi having a "sexual encounter." Ravi is also accused of trying unsuccessfully to broadcast a second sex scene Sept. 21.
"Jumping off the gw bridge sorry."I'm interested in how an incident like this becomes a major story in both the mainstream media and blogosphere, even though it might seem to be a strictly local story that's affected a relatively tiny number of people. What is it about this story? Suicide? Homophobia? Using internet technology to bully and invade someone's privacy? Don't all those things happen all the time?
Well, none of the elements are new, but they intersected dramatically enough to grab our attention. So it's understandable that the news and blogs are covering this so widely.
But I wish the shaming of gays weren't something we passively accepted as just-the-way-young-people-are, until something like this happens. It shouldn't take a death to make homophobia temporarily worth expressing concern over. Virulent homophobia — especially among youths, who tend to have low inhibitions about broadcasting their bigotry and a strong interest in building up their reputations by tearing down their peers' — is a huge, national problem whether or not it ever kills anyone.

How the iPhone helps a blind person...
. . . see?
From that blog post (via):
I have seen a lot of technology for the blind, and I can safely say that the iPhone represents the most revolutionary thing to happen to the blind for at least the last ten years. Fifteen or twenty years brings us back to the Braille ‘n Speak, which I loved in the same way, so have a hard time choosing the greater. In my more excitable moments, I consider the iPhone as the greatest thing to have ever happened to the blind, and it may prove so. . . . The touchpad offers the familiar next/previous motion which the blind need, since speech offers one-dimensional output. Adding the ability to touch anywhere on the screen and hear it adds a whole other dimension, literally. For the first time, the blind can actually get spacial information about something. In the store, Mom could say “Try that button” and I could. Blind people know what I mean. How many times has a sighted person said “I see an icon at the top of the screen?” Now, that actually Means something. . . .
The other night, . . . a very amazing thing happened. I downloaded an app called Color ID. It uses the iPhone’s camera, and speaks names of colors. It must use a table, because each color has an identifier made up of 6 hexadecimal digits. This puts the total at 16777216 colors, and I believe it. Some of them have very surreal names, such as Atomic Orange, Cosmic, Hippie Green, Opium, and Black-White. These names in combination with what feels like a rise in serotonin levels makes for a very psychedelic experience.
I have never experienced this before in my life. I can see some light and color, but just in blurs, and objects don’t really have a color, just light sources. When I first tried it at three o’clock in the morning, I couldn’t figure out why it just reported black. After realizing that the screen curtain also disables the camera, I turned it off, but it still have very dark colors. Then I remembered that you actually need light to see, and it probably couldn’t see much at night. I thought about light sources . . . . First, I saw one of my beautiful salt lamps in its various shades of orange, another with its pink and rose colors, and the third kind in glowing pink and red.. I felt stunned.
The next day, I went outside. I looked at the sky. I heard colors such as “Horizon,” “Outer Space,” and many shades of blue and gray. I used color [cues] to find my pumpkin plants, by looking for the green among the brown and stone. I spent ten minutes looking at my pumpkin plants, with their leaves of green and lemon-ginger. I then roamed my yard, and saw a blue flower. I then found the brown shed, and returned to the gray house. My mind felt blown. I watched the sun set, listening to the colors change as the sky darkened. The next night, I had a conversation with Mom about how the sky looked bluer tonight. Since I can see some light and color, I think hearing the color names can help nudge my perception, and enhance my visual experience. Amazing!
