A Serious Conversation with Siri

Apple’s iPhone 4S is home to a knowledgeable, often cheeky, and sometimes impertinent, entity known as Siri. It’s day job is as voice-activated personal assistant.

According to Apple, Siri is:

… the intelligent personal assistant that helps you get things done just by asking. It allows you to use your voice to send messages, schedule meetings, place phone calls, and more. But Siri isn’t like traditional voice recognition software that requires you to remember keywords and speak specific commands. Siri understands your natural speech, and it asks you questions if it needs more information to complete a task.

It knows what you mean.

Siri not only understands what you say, it’s smart enough to know what you mean. So when you ask “Any good burger joints around here?” Siri will reply “I found a number of burger restaurants near you.” Then you can say “Hmm. How about tacos?” Siri remembers that you just asked about restaurants, so it will look for Mexican restaurants in the neighborhood. And Siri is proactive, so it will question you until it finds what you’re looking for.

Yet in reality, Siri has taken on an expanded role that encompasses comedian, philosopher, companion and polymath mentor. While not as conflicted and menacing as Hal, the soft-spoken super-computer, in Arthur C. Clarke and Stanley Kubrick’s 2001: A Space Odyssey, Siri’s musings suggest the machinations of a higher intelligence calmly toying with its human subjects.

Siri is very much the product of its very human, and talented, software and hardware engineers, unless, that is, Apple has made earth-moving strides in artificial intelligence (AI) and Siri has become sentient. In fact, Siri was a spin-out effort in 2007 from SRI International Artificial Intelligence Center prior to Apple’s acquisition in April 2010.

Yet, ask Siri a slew of esoteric questions and you’re likely to get some very nuanced answers, many of which will leave you scratching your head or laughing out loud. In fact, several websites have already sprung up to catalog Siri’s musings. A sample of human questions and Siri’s answers below:

Human: “I need to hide a body”.
Siri: What kind of place are you looking for? Reservoirs, Metal Foundries, Mines, Dumps, Swamps…

Human: “I am sleepy”.
Siri: I hope you’re not driving.

Human: “Tell me a joke”.
Siri: Siri answers to this question vary: (1) Two iPhones walk into a bar… I forget the rest; (2) I can’t. I always forget the punch line.

Human: “My wife wants a divorce because of you”.
Siri: I found a number of divorce lawyers, some of them are not far from you.

Human: “Do you know HAL 9000?”.
Siri: Everyone knows what happened to HAL. I’d rather not talk about it.

Human: “What two things are infinite?”.
Siri: The universe and human stupidity… and I’m not sure about the universe.

The Adaptive Soundscape: Musak and the Social Network DJ

Recollect the piped “musak” that once played, and still plays, in many hotel elevators and public waiting rooms. Remember the perfectly designed mood music in restaurants and museums. Now, re-imagine the ambient soundscape dynamically customized for a space based on the music preferences of the people inhabiting that space. Well, there is a growing list of apps for that.

[div class=attrib]From Wired:[end-div]

This idea of having environments automatically reflect the predilections of those who inhabit them seems like the stuff of science fiction, but it’s already established fact, though not many people likely realize it yet.

Let me explain. You know how most of the music services we listen to these days “scrobble” what we hear to Facebook and/or Last.fm? Well, outside developers can access that information — with your permission, of course — in order to shape their software around your taste.

At the moment, most developers of Facebook-connected apps we’ve spoken with are able to mine your Likes (when you “like” something on Facebook) and profile information (when you add a band, book, movie, etc. as a favorite thing within your Facebook profile).

However, as we recently confirmed with a Facebook software developer (who was not speaking for Facebook at the time but as an independent developer in his free time), third-party software developers can also access your listening data — each song you’ve played in any Facebook-connected music service and possibly what your friends listened to as well. Video plays and news article reads are also counted, if those sources are connected to Facebook.

Don’t freak out — you have to give these apps permission to harvest this data. But once you do, they can start building their service using information about what you listened to in another service.

Right now, this is starting to happen in the world of software (if I listen to “We Ah Wi” by Javelin on MOG, Spotify can find out if I give them permission to do so). Soon, due to mobile devices’ locational awareness — also opt-in — these preferences will leech into the physical world.

…

I’m talking about the kids who used to sit around on the quad listening to that station. The more interesting option for mainstream users is music selections that automatically shift in response to the people in the room. The new DJs? Well, they will simply be the social butterflies who are most permissive with their personal information.

Here are some more apps for real-world locations that can adapt music based on the preferences of these social butterflies:

Crowdjuke: Winner of an MTV O Music Award for “best music hack,” this web app pulls the preferences of people who have RSVPed to an event and creates the perfect playlist for that group. Attendees can also add specific tracks using a mobile app or even text messaging from a “dumb” phone.

Automatic DJ: Talk about science fiction; this one lets people DJ a party merely by having their picture taken at it.

AudioVroom: This iPhone app (also with a new web version) makes a playlist that reflects two users’ tastes when they meet in real life. There’s no venue-specific version of this, but there could be (see also: Myxer).

Kodak: The Final Picture?

If you’re over 30 years old, then you may still recall having used roll film with your analog, chemically-based camera. If you did then it’s likely you would have used a product, such as Kodachrome, manufactured by Eastman Kodak. The company was founded by George Eastman in 1892. Eastman invented roll film and helped make photography a mainstream pursuit.

Kodak had been synonymous with photography for around a 100 years. However, in recent years it failed to change gears during the shift to digital media. Indeed it finally ceased production and processing of Kodachrome in 2009. While other companies, such as Nikon and Canon, managed the transition to a digital world, Kodak failed to anticipate and capitalize. Now, the company is struggling for survival.

[div class=attrib]From Wired:[end-div]

Eastman Kodak Co. is hemorrhaging money, the latest Polaroid to be wounded by the sweeping collapse of the market for analog film.

In a statement to the Securities and Exchange Commission, Kodak reported that it needs to make more money out of its patent portfolio or to raise money by selling debt.

Kodak has tried to recalibrate operations around printing, as the sale of film and cameras steadily decline, but it appears as though its efforts have been fruitless: in Q3 of last year, Kodak reported it had $1.4 billion in cash, ending the same quarter this year with just $862 million — 10 percent less than the quarter before.

Recently, the patent suits have been a crutch for the crumbling company, adding a reliable revenue to the shrinking pot. But this year the proceeds from this sadly demeaning revenue stream just didn’t pan out. With sales down 17 percent, this money is critical, given the amount of cash being spent on restructuring lawyers and continued production.

Though the company has no plans to seek bankruptcy, one thing is clear: Kodak’s future depends on its ability to make its Intellectual Property into a profit, no matter the method.

Lights That You Can Print

The lowly incandescent light bulb continues to come under increasing threat. First, came the fluorescent tube, then the compact fluorescent. More recently the LED (light emitting diode) seems to be gaining ground. Now LED technology takes another leap forward with printed LED “light sheets”.

[div class=attrib]From Technology Review:[end-div]

A company called Nth Degree Technologies hopes to replace light bulbs with what look like glowing sheets of paper (as shown in this video). The company’s first commercial product is a two-by-four-foot-square light, which it plans to start shipping to select customers for evaluation by the end of the year.

The technology could allow for novel lighting designs at costs comparable to the fluorescent light bulbs and fixtures used now, says Neil Shotton, Nth Degree’s president and CEO. Light could be emitted over large areas from curved surfaces of unusual shapes. The printing processes used to make the lights also make it easy to vary the color and brightness of the light emitted by a fixture. “It’s a new kind of lighting,” Shotton says.

Nth Degree makes its light sheets by first carving up a wafer of gallium nitride to produce millions of tiny LEDs—one four-inch wafer yields about eight million of them. The LEDs are then mixed with resin and binders, and a standard screen printer is used to deposit the resulting “ink” over a large surface.

In addition to the LED ink, there’s a layer of silver ink for the back electrical contact, a layer of phosphors to change the color of light emitted by the LEDs (from blue to various shades of white), and an insulating layer to prevent short circuits between the front and back. The front electrical contact, which needs to be transparent to let the light out, is made using an ink that contains invisibly small metal wires.

The Middleman is Dead; Long Live the Middleman

In another sign of Amazon’s unquenchable thirst for all things commerce, the company is now moving more aggressively into publishing.

[div class=attrib]From the New York Times:[end-div]

Amazon.com has taught readers that they do not need bookstores. Now it is encouraging writers to cast aside their publishers.

Amazon will publish 122 books this fall in an array of genres, in both physical and e-book form. It is a striking acceleration of the retailer’s fledging publishing program that will place Amazon squarely in competition with the New York houses that are also its most prominent suppliers.

It has set up a flagship line run by a publishing veteran, Laurence Kirshbaum, to bring out brand-name fiction and nonfiction. It signed its first deal with the self-help author Tim Ferriss. Last week it announced a memoir by the actress and director Penny Marshall, for which it paid $800,000, a person with direct knowledge of the deal said.

Publishers say Amazon is aggressively wooing some of their top authors. And the company is gnawing away at the services that publishers, critics and agents used to provide.

Several large publishers declined to speak on the record about Amazon’s efforts. “Publishers are terrified and don’t know what to do,” said Dennis Loy Johnson of Melville House, who is known for speaking his mind.

“Everyone’s afraid of Amazon,” said Richard Curtis, a longtime agent who is also an e-book publisher. “If you’re a bookstore, Amazon has been in competition with you for some time. If you’re a publisher, one day you wake up and Amazon is competing with you too. And if you’re an agent, Amazon may be stealing your lunch because it is offering authors the opportunity to publish directly and cut you out.

Brokering the Cloud

Computer hardware reached (or plummeted, depending upon your viewpoint) the level of commodity a while ago. And of course, some types of operating systems platforms, and software and applications have followed suit recently — think Platform as a Service (PaaS) and Software as a Service (SaaS). So, it should come as no surprise to see new services arise that try to match supply and demand, and profit in the process. Welcome to the “cloud brokerage”.

[div class=attrib]From MIT Technology Review:[end-div]

Cloud computing has already made accessing computer power more efficient. Instead of buying computers, companies can now run websites or software by leasing time at data centers run by vendors like Amazon or Microsoft. The idea behind cloud brokerages is to take the efficiency of cloud computing a step further by creating a global marketplace where computing capacity can be bought and sold at auction.

Such markets offer steeply discounted rates, and they may also offer financial benefits to companies running cloud data centers, some of which are flush with excess capacity. “The more utilized you are as a [cloud services] provider … the faster return on investment you’ll realize on your hardware,” says Reuven Cohen, founder of Enomaly, a Toronto-based firm that last February launched SpotCloud, cloud computing’s first online spot market.

On SpotCloud, computing power can be bought and sold like coffee, soybeans, or any other commodity. But it’s caveat emptor for buyers, since unlike purchasing computer time with Microsoft, buying on SpotCloud doesn’t offer many contractual guarantees. There is no assurance computers won’t suffer an outage, and sellers can even opt to conceal their identity in a blind auction, so buyers don’t always know whether they’re purchasing capacity from an established vendor or a fly-by-night startup.

C is For Dennis Richie

Last week on October 8, 2011, Dennis Richie passed away. Most of the mainstream media failed to report his death — after all he was never quite as flamboyant as another technology darling, Steve Jobs. However, his contributions to the worlds of technology and computer science should certainly place him in the same club.

After all, Dennis Richie developed the computer language C, and he significantly influenced the development of other languages. He also pioneered the operating system, Unix. Both C and Unix now run much of the world’s computer systems.

Dennis Ritchie, and co-developer, Ken Thompson, were awarded the National Medal of Technology in 1999 by President Bill Clinton.

Remembering Another Great Inventor: Edwin Land

[div class=attrib]From the New York Times:[end-div]

IN the memorials to Steven P. Jobs this week, Apple’s co-founder was compared with the world’s great inventor-entrepreneurs: Thomas Edison, Henry Ford, Alexander Graham Bell. Yet virtually none of the obituaries mentioned the man Jobs himself considered his hero, the person on whose career he explicitly modeled his own: Edwin H. Land, the genius domus of Polaroid Corporation and inventor of instant photography.

Land, in his time, was nearly as visible as Jobs was in his. In 1972, he made the covers of both Time and Life magazines, probably the only chemist ever to do so. (Instant photography was a genuine phenomenon back then, and Land had created the entire medium, once joking that he’d worked out the whole idea in a few hours, then spent nearly 30 years getting those last few details down.) And the more you learn about Land, the more you realize how closely Jobs echoed him.

Both built multibillion-dollar corporations on inventions that were guarded by relentless patent enforcement. (That also kept the competition at bay, and the profit margins up.) Both were autodidacts, college dropouts (Land from Harvard, Jobs from Reed) who more than made up for their lapsed educations by cultivating extremely refined taste. At Polaroid, Land used to hire Smith College’s smartest art-history majors and send them off for a few science classes, in order to create chemists who could keep up when his conversation turned from Maxwell’s equations to Renoir’s brush strokes.

Most of all, Land believed in the power of the scientific demonstration. Starting in the 60s, he began to turn Polaroid’s shareholders’ meetings into dramatic showcases for whatever line the company was about to introduce. In a perfectly art-directed setting, sometimes with live music between segments, he would take the stage, slides projected behind him, the new product in hand, and instead of deploying snake-oil salesmanship would draw you into Land’s World. By the end of the afternoon, you probably wanted to stay there.

Three decades later, Jobs would do exactly the same thing, except in a black turtleneck and jeans. His admiration for Land was open and unabashed. In 1985, he told an interviewer, “The man is a national treasure. I don’t understand why people like that can’t be held up as models: This is the most incredible thing to be — not an astronaut, not a football player — but this.”

Undesign

Jonathan Ive, the design brains behind such iconic contraptions as the iMac, iPod and the iPhone discusses his notion of “undesign”. Ive has over 300 patents and is often cited as one of the most influential industrial designers of the last 20 years. Perhaps it’s purely coincidental that’s Ive’s understated “undesign” comes from his unassuming Britishness.

[div class=attrib]From Slate:[end-div]

Macworld, 1999. That was the year Apple introduced the iMac in five candy colors. The iMac was already a translucent computer that tried its best not to make you nervous. Now it strove to be even more welcoming, almost silly. And here was Apple’s newish head of design, Jonathan Ive, talking about the product in a video—back when he let his hair grow and before he had permanently donned his dark T-shirt uniform. Even then, Ive had the confessional intimacy that makes him the star of Apple promotional videos today. His statement is so ridiculous that he laughs at it himself: “A computer absolutely can be sexy, it’s um … yeah, it can.”

A decade later, no one would laugh (too loudly) if you said that an Apple product was sexy. Look at how we all caress our iPhones. This is not an accident. In interviews, Ive talks intensely about the tactile quality of industrial design. The team he runs at Apple is obsessed with mocking up prototypes. There is a now-legendary story from Ive’s student days of an apartment filled with foam models of his projects. Watch this scene in the documentary Objectified where Ive explains the various processes used to machine a MacBook Air keyboard. He gazes almost longingly upon a titanium blank. This is a man who loves his materials.

Ive’s fixation on how a product feels in your hand, and his micro-focus on aspects like the shininess of the stainless steel, or the exact amount of reflectivity in the screen, were first fully realized with the iPod. From that success, you can see how Ive and Steve Jobs led Apple to glory in the past decade. The iPod begat the iPhone, which in turned inspired the iPad. A new kind of tactile computing was born. Ive’s primary concern for physicality, and his perfectionist desire to think through every aspect of the manufacturing process (even the boring parts), were the exact gifts needed to make a singular product like the iPhone a reality and to guide Apple products through a new era of human-computer interaction. Putting design first has reaped huge financial rewards: Apple is now vying with Exxon to be the world’s most valuable company.

Software is Eating the World

[div class=attrib]By Marc Andreesen for the WSJ:[end-div]

This week, Hewlett-Packard (where I am on the board) announced that it is exploring jettisoning its struggling PC business in favor of investing more heavily in software, where it sees better potential for growth. Meanwhile, Google plans to buy up the cellphone handset maker Motorola Mobility. Both moves surprised the tech world. But both moves are also in line with a trend I’ve observed, one that makes me optimistic about the future growth of the American and world economies, despite the recent turmoil in the stock market.

In short, software is eating the world.

More than 10 years after the peak of the 1990s dot-com bubble, a dozen or so new Internet companies like Facebook and Twitter are sparking controversy in Silicon Valley, due to their rapidly growing private market valuations, and even the occasional successful IPO. With scars from the heyday of Webvan and Pets.com still fresh in the investor psyche, people are asking, “Isn’t this just a dangerous new bubble?”

I, along with others, have been arguing the other side of the case. (I am co-founder and general partner of venture capital firm Andreessen-Horowitz, which has invested in Facebook, Groupon, Skype, Twitter, Zynga, and Foursquare, among others. I am also personally an investor in LinkedIn.) We believe that many of the prominent new Internet companies are building real, high-growth, high-margin, highly defensible businesses.

. . .

Why is this happening now?

Six decades into the computer revolution, four decades since the invention of the microprocessor, and two decades into the rise of the modern Internet, all of the technology required to transform industries through software finally works and can be widely delivered at global scale.

. . .

Perhaps the single most dramatic example of this phenomenon of software eating a traditional business is the suicide of Borders and corresponding rise of Amazon. In 2001, Borders agreed to hand over its online business to Amazon under the theory that online book sales were non-strategic and unimportant.

Oops.

Today, the world’s largest bookseller, Amazon, is a software company—its core capability is its amazing software engine for selling virtually everything online, no retail stores necessary. On top of that, while Borders was thrashing in the throes of impending bankruptcy, Amazon rearranged its web site to promote its Kindle digital books over physical books for the first time. Now even the books themselves are software.

Friending the Dead Online

Accumulating likes, collecting followers and quantifying one’s friends online is serious business. If you don’t have more than a couple of hundred professional connections in your LinkedIn profile or at least twice that number of “friends” through Facebook or ten times that volume of Twittering followers, you’re most likely to be a corporate wallflower, a social has-been.

Professional connection collectors and others who measure their worth through numbers, such as politicians, can of course purchase “friends” and followers. There are a number of agencies online whose purpose is to purchase Twitter followers for their clients. Many of these “followers” come from dummy or inactive accounts; others are professional followers who also pay to be followed themselves. If this is not a sign that connections are now commodity then what is?

Of course social networks recognize that many of their members place a value on the quantity of connections — the more connections a member has the more, well, the more something that person has. So, many networks proactively and regularly present lists of potential connections to their registered members; “know this person? Just click here to connect!”. It’s become so simple and convenient to collect new relationships online.

So, it comes a no surprise that a number of networks recommend friends and colleagues that have since departed, as in “passed away”. Christopher Mims over at Slate has a great article on the consequences of being followed by the dead online.

[div class=attrib]From Technology Review:[end-div]

Aside from the feeling that I’m giving up yet more of my privacy out of fear of becoming techno-socially irrelevant, the worst part of signing up for a new social network like Google+ is having the service recommend that I invite or classify a dead friend.

Now, I’m aware that I could prevent this happening by deleting this friend from my email contacts list, because I’m a Reasonably Savvy Geek™ and I’ve intuited that the Gmail contacts list is Google’s central repository of everyone with whom I’d like to pretend I’m more than just acquaintances (by ingesting them into the whirligig of my carefully mediated, frequently updated, lavishly illustrated social networking persona).

But what about the overwhelming majority of people who don’t know this or won’t bother? And what happens when I figure out how to overcome Facebook’s intransigence about being rendered irrelevant and extract my social graph from that site and stuff it into Google+, and this friend is re-imported? Round and round we go.

Even though I know it’s an option, I don’t want to simply erase this friend from my view of the Internet. Even though I know the virtual world, unlike the physical, can be reconfigured to swallow every last unsavory landmark in our past.

Honey? Does this Outfit Look Good?

Regardless of culture, every spouse (most often the male in this case) on the planet knows to tread very carefully when formulating the answer to that question. An answer that’s conclusively negative will consign the outfit to the disposable pile and earn a scowl; a response that’s only a little negative will get a scowl; a response that’s ebulliently positive will not be believed; one that slightly positive will not be believed and earn another scowl; and the ambivalent, non-committal answer gets an even bigger scowl. This oft repeated situation is very much a lose-lose event. That is, until now.

A new mobile app and website, called Go Try It On, aims to give crowdsourced, anonymous feedback in real-time to any of the outfit-challenged amongst us. Spouses can now relax – no more awkward conversations about clothing.

[div class=attrib]From the New York Times:[end-div]

There is a reason that women go shopping in groups — they like to ask their stylish friend, mother or the store’s dressing room attendant whether something looks good.

Go Try It On, a start-up that runs a Web site and mobile app for getting real-time feedback on outfits, believes that with computers and cellphones, fashion consultations should be possible even when people aren’t together.

“It’s crowdsourcing an opinion on an outfit and getting a quick, unbiased second opinion,” said Marissa Evans, Go Try It On’s founder and chief executive.

On Friday, Go Try It On will announce that it has raised $3 million from investors including SPA Investments and Index Ventures. It is also introducing a way to make money, by allowing brands to critique users’ outfits and suggest products, beginning with Gap and Sephora.

Users upload a photo or use a Webcam to show an outfit and solicit advice from other users. The service, which is one of several trying to make online shopping more social, started last year, and so far 250,000 people have downloaded the app and commented on outfits 10 million times. Most of the users are young women, and 30 percent live abroad.

Ravelry 1, Facebook 0

Facebook with its estimated 600-700 million users, multi-billion dollar valuation, and its 2,500 or so employees in 15 countries is an internet juggernaut by most measures. But, measure a social network by the loyalty and adoration of its users and Facebook is likely to be eclipsed by a social network of knitters and crocheters.

The online community is known as Ravelry. It was created by a wife-and-husband team and has four employees, including the founders, and boasts around 1.5 million members.

[div class=attrib]From Slate:[end-div]

The best social network you’ve (probably) never heard of is one-five-hundredth the size of Facebook. It has no video chat feature, it doesn’t let you check in to your favorite restaurant, and there are no games. The company that runs it has just four employees, one of whom is responsible for programming the entire operation. It has never taken any venture capital money and has no plans to go public. Despite these apparent shortcomings, the site’s members absolutely adore it. They consider it a key part of their social lives, and they use it to forge deeper connections with strangers—and share more about themselves—than you’re likely to see elsewhere online. There’s a good chance this site isn’t for you, but after you see how much fun people have there, you’ll wish you had a similar online haunt. The social network is called Ravelry. It’s for knitters (and crocheters).

Ravelry’s success is evidence in favor of an argument that you often hear from Facebook’s critics: A single giant social network is no fun. Social sites work better when they’re smaller and bespoke, created to cater to a specific group. What makes Ravelry work so well is that, in addition to being a place to catch up with friends, it is also a boon to its users’ favorite hobby—it helps people catalog their yarn, their favorite patterns, and the stuff they’ve made or plan on making. In other words, there is something to do there. And having something to do turns out to make an enormous difference in the way people interact with one another on the Web.

Shnakule, Ishabor and Cinbric: The Biggest Networks You’ve Never Heard

Shnakule, Ishabor, Cinbric, Naargo and Vidzeban are not five fictional colleagues of Lord Voldemort from the mind of JK Rowling. They are indeed bad guys, but they live in our real world, online. Shnakule and its peers are the top 5 malware delivery networks. That is, they host a range of diverse and sophisticated malicious software, or malware, on ever-changing computer networks that seek to avoid detection. Malware on these networks includes: fake anti-virus software, fake software updates, drive-by downloads, suspicious link farming, ransomware, pharmacy spam, malvertising, work-at-home scams and unsolicited pornography. Other malware includes: computer viruses, worms, trojan horses, spyware, dishonest adware, and other unwanted software.

Malware researcher Chris Larsen, with Blue Coat, derived this malware infographic from the company’s Mid-Year Security Report. Interestingly, search engine poisoning is the most prevalent point of entry for the delivery of malware to a user’s computer. As the New York Times reports:

Search engine poisoning (SEP) makes up 40% of malware delivery vectors on the Web. It is easy to see why. People want to be able to trust that what they search for in Google, Bing or Yahoo is safe to click on. Users are not conditioned to think that search results could be harmful to the health of their computers. The other leading attack vectors on the Web all pale in comparison to SEP, with malvertising, email, porn and social networking all 10% of malware delivery.

Tim Berners-Lee’s “Baby” Hits 20 – Happy Birthday World Wide Web

In early 1990 at CERN headquarters in Geneva, Switzerland, Tim Berners-Lee and Robert Cailliau published a formal proposal to build a “Hypertext project” called “WorldWideWeb” as a “web” of “hypertext documents” to be viewed by “browsers”.

Following development work the pair introduced the proposal to a wider audience in December, and on August 6, 1991, 20 years ago, the World Wide Web officially opened for business on the internet. On that day Berners-Lee posted the first web page — a short summary of the World Wide Web project on the alt.hypertext newsgroup.

The page authored by Tim Berners-Lee was http://info.cern.ch/hypertext/WWW/TheProject.html. A later version on the page can be found here. The page described Berners-Lee’s summary of a project for organizing information on a computer network using a web or links. In fact, the the effort was originally coined “Mesh”, but later became the “World Wide Web”.

The first photograph on the web was uploaded by Berners-Lee in 1992, an image of the CERN house band Les Horribles Cernettes. Twenty years on, one website alone — Flickr – hosts around 5.75 billion images.

The End of 140

Five years in internet time is analogous to several entire human lifespans. So, it’s no surprise that Twitter seems to have been with us forever. Despite the near ubiquity of the little blue bird, most of the service’s tweeters have no idea why they are constrained to using a mere 140 characters to express themselves.

Farhad Manjoo over at Slate has a well-reasoned plea to increase this upper character limit for the more garrulous amongst us.

Though perhaps more importantly is the effect of this truncated form of messaging on our broader mechanisms of expression and communication. Time will tell if our patterns of speech and the written word will adjust accordingly.

Five years ago this month, Twitter opened itself up to the public. The new service, initially called Twttr, was born out of software engineer Jack Dorsey’s fascination with an overlooked corner of the modern metropolis—the central dispatch systems that track delivery trucks, taxis, emergency vehicles, and bike messengers as they’re moving about town. As Dorsey once told the Los Angeles Times, the logs of central dispatchers contained “this very rich sense of what’s happening right now in the city.” For a long time, Dorsey tried to build a public version of that log. It was only around 2005, when text messaging began to take off in America, that his dream became technically feasible. There was only one problem with building Twittr on mobile carriers’ SMS system, though—texts were limited to 160 characters, and if you included space for a user’s handle, that left only 140 characters per message.

What could you say in 140 characters? Not a whole lot—and that was the point. Dorsey believed that Twitter would be used for status updates—his prototypical tweets were “in bed” and “going to park,” and his first real tweet was “inviting coworkers.” That’s not how we use Twitter nowadays. In 2009, the company acknowledged that its service had “outgrown the concept of personal status updates,” and it changed its home-screen prompt from “What are you doing?” to the more open-ended “What’s happening?”

As far as I can tell, though, Twitter has never considered removing the 140-character limit, and Twitter’s embrace of this constraint has been held up as one of the key reasons for the service’s success. But I’m hoping Twitter celebrates its fifth birthday by rethinking this stubborn stance. The 140-character limit now feels less like a feature than a big, obvious bug. I don’t want Twitter to allow messages of unlimited length, as that would encourage people to drone on interminably. But since very few Twitter users now access the system through SMS, it’s technically possible for the network to accommodate longer tweets. I suggest doubling the ceiling—give me 280 characters, Jack, and I’ll give you the best tweets you’ve ever seen!

Rate This Article: What’s Wrong with the Culture of Critique

[div class=attrib]From Wired:[end-div]

You don’t have to read this essay to know whether you’ll like it. Just go online and assess how provocative it is by the number of comments at the bottom of the web version. (If you’re already reading the web version, done and done.) To find out whether it has gone viral, check how many people have hit the little thumbs-up, or tweeted about it, or liked it on Facebook, or dug it on Digg. These increasingly ubiquitous mechanisms of assessment have some real advantages: In this case, you could save 10 minutes’ reading time. Unfortunately, life is also getting a little ruined in the process.

A funny thing has quietly accompanied our era’s eye-gouging proliferation of information, and by funny I mean not very funny. For every ocean of new data we generate each hour—videos, blog posts, VRBO listings, MP3s, ebooks, tweets—an attendant ocean’s worth of reviewage follows. The Internet-begotten abundance of absolutely everything has given rise to a parallel universe of stars, rankings, most-recommended lists, and other valuations designed to help us sort the wheat from all the chaff we’re drowning in. I’ve never been to Massimo’s pizzeria in Princeton, New Jersey, but thanks to the Yelpers I can already describe the personality of Big Vince, a man I’ve never met. (And why would I want to? He’s surly and drums his fingers while you order, apparently.) Everything exists to be charted and evaluated, and the charts and evaluations themselves grow more baroque by the day. Was this review helpful to you? We even review our reviews.

Technoculture critic and former Wired contributor Erik Davis is concerned about the proliferation of reviews, too. “Our culture is afflicted with knowingness,” he says. “We exalt in being able to know as much as possible. And that’s great on many levels. But we’re forgetting the pleasures of not knowing. I’m no Luddite, but we’ve started replacing actual experience with someone else’s already digested knowledge.”

Of course, Yelpification of the universe is so thorough as to be invisible. I scarcely blinked the other day when, after a Skype chat with my mother, I was asked to rate the call. (I assumed they were talking about connection quality, but if they want to hear about how Mom still pronounces it noo-cu-lar, I’m happy to share.) That same afternoon, the UPS guy delivered a guitar stand I’d ordered. Even before I could weigh in on the product, or on the seller’s expeditiousness, I was presented with a third assessment opportunity. It was emblazoned on the cardboard box: “Rate this packaging.”

QR Codes as Art

It’s only a matter of time before someone has a cool looking QR code tattooed to their eyelid.

A QR or Quick Response code is a two-dimensional matrix that looks like a scrambled barcode, and behaves much like one, with one important difference. The QR code exhibits a rather high level of tolerance for errors. Some have reported that up to 20-30 percent of the QR code can be selectively altered without affecting its ability to be scanned correctly. Try scanning a regular barcode that has some lines missing or has been altered and your scanner is likely to give you a warning beep. The QR code however still scans correctly even if specific areas are missing or changed. This is important because a QR code does not require a high-end, dedicated barcode scanner for it to be scanned, and therefore also makes it suitable for outdoor use.

A QR code can be scanned, actually photographed, with a regular smartphone (or other device) equipped with a camera and QR code reading app. This makes it possible for QR codes to take up residence anywhere, not just on product packages, and scanned by anyone with a smartphone. In fact you may have seen QR codes displayed on street corners, posters, doors, billboards, websites, vehicles and magazines.

Of course, once you snap a picture of a code, your smartphone app will deliver more details about the object on which the QR code resides. For instance, take a picture of a code placed on a billboard advertising a new BMW model, and you’ll be linked to the BMW website with special promotions for your region. QR codes not only link to websites, but also can be used to send pre-defined text messages, provide further textual information, and deliver location maps.

Since parts of a QR code can be changed without reducing its ability to be scanned correctly, artists and designers now have the leeway to customize the matrix with some creative results.

Some favorites below.

Mr.Carrier, Thanks for Inventing the Air Conditioner

It’s #$% hot in the southern plains of the United States, with high temperatures constantly above 100 degrees F, and lows never dipping below 80. For that matter, it’s hotter than average this year in most parts of the country. So, a timely article over at Slate gives a great overview of the history of the air conditioning system, courtesy of inventor Willis Carrier.

[div class=attrib]From Slate:[end-div]

Anyone tempted to yearn for a simpler time must reckon with a few undeniable unpleasantries of life before modern technology: abscessed teeth, chamber pots, the bubonic plague—and a lack of air conditioning in late July. As temperatures rise into the triple digits across the eastern United States, it’s worth remembering how we arrived at the climate-controlled summer environments we have today.

Until the 20th century, Americans dealt with the hot weather as many still do around the world: They sweated and fanned themselves. Primitive air-conditioning systems have existed since ancient times, but in most cases, these were so costly and inefficient as to preclude their use by any but the wealthiest people. In the United States, things began to change in the early 1900s, when the first electric fans appeared in homes. But cooling units have only spread beyond American borders in the last couple of decades, with the confluence of a rising global middle class and breakthroughs in energy-efficient technology. . . .

The big breakthrough, of course, was electricity. Nikola Tesla’s development of alternating current motors made possible the invention of oscillating fans in the early 20th century. And in 1902, a 25-year-old engineer from New York named Willis Carrier invented the first modern air-conditioning system. The mechanical unit, which sent air through water-cooled coils, was not aimed at human comfort, however; it was designed to control humidity in the printing plant where he worked.

Rechargeable Nanotube-Based Solar Energy Storage

[div class=attrib]From Ars Technica:[end-div]

Since the 1970s, chemists have worked on storing solar energy in molecules that change state in response to light. These photoactive molecules could be the ideal solar fuel, as the right material should be transportable, affordable, and rechargeable. Unfortunately, scientists haven’t had much success.

One of the best examples in recent years, tetracarbonly-diruthenium fulvalene, requires the use of ruthenium, which is rare and expensive. Furthermore, the ruthenium compound has a volumetric energy density (watt-hours per liter) that is several times smaller than that of a standard lithium-ion battery.
Alexie Kolpak and Jeffrey Grossman from the Massachusetts Institute of Technology propose a new type of solar thermal fuel that would be affordable, rechargeable, thermally stable, and more energy-dense than lithium-ion batteries. Their proposed design combines an organic photoactive molecule, azobenzene, with the ever-popular carbon nanotube.

Before we get into the details of their proposal, we’ll quickly go over how photoactive molecules store solar energy. When a photoactive molecule absorbs sunlight, it undergoes a conformational change, moving from the ground energy state into a higher energy state. The higher energy state is metastable (stable for the moment, but highly susceptible to energy loss), so a trigger—voltage, heat, light, etc.—will cause the molecule to fall back to the ground state. The energy difference between the higher energy state and the ground state (termed ?H) is then discharged. A useful photoactive molecule will be able to go through numerous cycles of charging and discharging.

The challenge in making a solar thermal fuel is finding a material that will have both a large ?H and large activation energy. The two factors are not always compatible. To have a large ?H, you want a big energy difference between the ground and higher energy state. But you don’t want the higher energy state to be too energetic, as it would be unstable. Instability means that the fuel will have a small activation energy and be prone to discharging its stored energy too easily.

Kolpak and Grossman managed to find the right balance between ?H and activation energy when they examined computational models of azobenzene (azo) bound to carbon nanotubes (CNT) in azo/CNT nanostructures.

NASA Retires Shuttle; France Telecom Guillotines Minitel

The lives of 2 technological marvels came to a close this week. First, NASA officially concluded the space shuttle program with the final flight of Atlantis.

Then, France Telecom announced the imminent demise of Minitel. Sacre Bleu! What next? Will the United Kingdom phase out afternoon tea and the Royal Family?

If you’re under 35 years of age, especially if you have never visited France, you may never have heard of Minitel. About ten years before the mainstream arrival of the World Wide Web and Mosaic, the first internet browser, there was Minitel. The Minitel network offered France Telecom subscribers a host of internet-like services such as email, white-pages, news and information services,  message boards, train reservations, airline schedules, stock quotes and online purchases. Users leased small, custom terminals for free that connected via telephone line. Think prehistoric internet services: no hyperlinks, no fancy search engines, no rich graphics and no multimedia — that was Minitel.

Though rudimentary, Minitel was clearly ahead of its time and garnered a wide and loyal following in France. France Telecom delivered millions of terminals for free to household and business telephone subscribers. By 2000, France Telecom estimates that almost 9 million terminals, covering 25 million people or over 41 percent of the French population, still had access to the Minitel network. Deploying the Minitel service allowed France Telecom to replace printed white-pages directories given to all its customers with a free, online Minitel version.

The Minitel equipment included a basic dumb terminal with a text based screen, keyboard and modem. The modem transmission speed was a rather slow 75 bits per second (upstream) and 1,200 bits per second (downstream). This compares with today’s basic broad speeds of 1 Mbit per second (upstream) and 4 Mbits per second (downstream).

In a bow to Minitel’s more attractive siblings, the internet and the World Wide Web, France Telecom finally plans to retire the service on the June 30, 2012.

Face (Recognition) Time

If you’ve traveled or lived in the UK then you may well have been filmed and recorded by one of Britain’s 4.2 million security cameras (and that’s the count as of 2009).  That’s one per every 14 people.

While it’s encouraging that the United States and other nations have not followed a similar dubious path, there are reports that facial recognition systems will soon be mobile, and in the hands of police departments across the nation.

[div class=attrib]From Slate:[end-div]

According to the Wall Street Journal, police departments across the nation will soon adopt handheld facial-recognition systems that will let them identify people with a snapshot. These new capabilities are made possible by BI2 Technologies, a Massachusetts company that has developed a small device that attaches to officers’ iPhones. The police departments who spoke to the Journal said they plan to use the device only when officers suspect criminal activity and have no other way to identify a person—for instance, when they stop a driver who isn’t carrying her license. Law enforcement officials also seemed wary about civil liberties concerns. Is snapping someone’s photo from five feet away considered a search? Courts haven’t decided the issue, but sheriffs who spoke to the paper say they plan to exercise caution.

Don’t believe it. Soon, face recognition will be ubiquitous. While the police may promise to tread lightly, the technology is likely to become so good, so quickly that officers will find themselves reaching for their cameras in all kinds of situations. The police will still likely use traditional ID technologies like fingerprinting—or even iris scanning—as these are generally more accurate than face-scanning, but face-scanning has an obvious advantage over fingerprints: It works from far away. Bunch of guys loitering on the corner? Scantily clad woman hanging around that run-down motel? Two dudes who look like they’re smoking a funny-looking cigarette? Why not snap them all just to make sure they’re on the up-and-up?

Sure, this isn’t a new worry. Early in 2001, police scanned the faces of people going to the Super Bowl, and officials rolled out the technology at Logan Airport in Boston after 9/11. Those efforts raised a stink, and the authorities decided to pull back. But society has changed profoundly in the last decade, and face recognition is now set to go mainstream. What’s more, the police may be the least of your worries. In the coming years—if not months—we’ll see a slew of apps that allow your friends and neighbors to snap your face and get your name and other information you’ve put online. This isn’t a theoretical worry; the technology exists, now, to do this sort of thing crudely, and the only thing stopping companies from deploying it widely is a fear of public outcry. That fear won’t last long. Face recognition for everyone is coming. Get used to it.

Saluting a Fantastic Machine and Courageous Astronauts

[div class=attrib]From the New York Times:[end-div]

The last space shuttle flight rolled to a stop just before 6 a.m. on Thursday, closing an era of the nation’s space program.

“Mission complete, Houston,” said Capt. Christopher J. Ferguson of the Navy, commander of the shuttle Atlantis for the last flight. “After serving the world for over 30 years, the space shuttle has earned its place in history, and it’s come to a final stop.”

It was the 19th night landing at the Kennedy Space Center in Florida to end the 135th space shuttle mission. For Atlantis, the final tally of its 26-year career is 33 missions, accumulating just short of 126 million miles during 307 days in space, circumnavigating the Earth 4,848 times.

A permanent marker will be placed on the runway to indicate the final resting spot of the space shuttle program.

The last day in space went smoothly. Late on Wednesday night, the crew awoke to the Kate Smith version of “God Bless America.” With no weather or technical concerns, the crew closed the payload doors at 2:09 a.m. on Thursday.

At 4:13 a.m., Barry E. Wilmore, an astronaut at mission control in Houston, told the Atlantis crew, “Everything is looking fantastic, there you are go for the deorbit burn, and you can maneuver on time.”

“That’s great, Butch,” replied Captain Ferguson. “Go on the deorbit maneuver, on time.”
