Personal Cloud Search

I remember Google once brought this thing that allowed you to search through your Desktop. I quite liked it. It was a nice toy. But I mostly remembered where my stuff were. But, hey, search!

A Simple Way to Search Your Share of the Cloud
A company called ClipCard will let you search all your cloud-based stuff at once, even if it’s stored in several places.

Pinterest Dwarfing Facebook?



Pinterest dwarfing Twitter is yesterday's news. But Pinterest dwarfing Facebook?

Inside Pinterest: The Coming Ad Colossus That Could Dwarf Twitter And Facebook
A visual social network where people create and share image collections of recipes, hairstyles, baby furniture and just about anything else on their phones or computers, Pinterest isn’t yet five years old, but among women, who make up over 80% of its users, it’s already more popular than Twitter, which has a market capitalization of more than $30 billion. Pinterest’s U.S. user base is projected to top 40 million this year, putting it in a league with both Twitter and Instagram domestically ........ To date, Pinterest’s users have created more than 750 million boards made up of more than 30 billion individual pins, with 54 million new ones added each day. During the 2013 holiday season Pinterest accounted for nearly a quarter of all social sharing activity. Among social networks, only Facebook, with its 1.3 billion users, drives more traffic to Web publishers. ...... on the basis of average revenue per user, it’s only a matter of time before Pinterest blows past Facebook, Twitter and the rest of the social pack. ...... As Silbermann explains it, Facebook “is about your connections, your past events, your memories.” Users on Facebook volunteer a staggering amount of retrospective information such as birthplace, alma mater and vacations, data the company can use to power its highly targeted ad offerings. Twitter can’t offer that level of detail, which is why its revenue per user, at around $3.50, is only half that of Facebook’s. Twitter’s value remains stuck in the now, promising advertisers a presence in real-time conversations about the World Cup, a presidential election or Orange Is the New Black........ If Facebook is selling the past and Twitter the present, Pinterest is offering the future. “It’s about what you aspire to do, what you want to do down the line,” says Silbermann. And the future is where marketers want to live. ..... that delicate moment when browsing becomes shopping ..... For now advertising is Pinterest’s only revenue line. But it requires only the tiniest leap to conjure a scenario in which the company acts as middleman for the hundreds of thousands of retailers already showcasing their wares on its platform. ..... This is Amazon’s turf, but Facebook and Twitter have been making incursions, with both companies conducting tests of “Buy” buttons for frictionless shopping. ..... In his Cannes keynote Silbermann dismissed Google as “the ultimate card catalog,” an outdated technology useful only if you already know what you’re looking for. ..... Pinterest, he says, “exposes people to possibilities they never would have known existed.” ..... Silbermann grew up thinking he’d be a doctor like his parents, both of whom are ophthalmologists. An accomplished cellist and debater, he spent the summer before his senior year in high school at MIT’s elite Research Science Institute and then enrolled at Yale, where he took premed courses. Halfway through college, though, he caught the business bug. Instead of taking the MCAT upon graduation, he took a job as a management consultant at the Corporate Executive Board in Washington, D.C. “Like a lot of young people, I just wanted a job at the beginning,” he says of taking the road more traveled. ........ After three years as a consultant he scored “ the only job I could get at Google,” as a product specialist, and moved out West in 2006. Silbermann spent his days translating customer feedback into product refinements, acquiring a skill he considers crucial to Pinterest’s success. ...... Silbermann was visiting New York when he met through a mutual friend a Columbia architecture student named Evan Sharp. “We both had the same hobby, which was the Internet,” Sharp says. “I grew up in rural Pennsylvania, and Ben grew up in Des Moines. For both of us, in a way, the Internet was this really precious window into worlds outside our day-to-day experience.” ....... Sharp told Silbermann about his collection of thousands of architectural drawings and photos, which had become increasingly hard to organize. That resonated with Silbermann, who’d noticed that Tote’s users seemed more interested in saving photos of products than in buying the products themselves. ...... the three launched the first desktop version of Pinterest in March 2010. Users could save images from anywhere on the Web to thematically organized boards ..... As the work progressed, Sharp moved to the Bay Area and took a job at Facebook to support himself while the three worked from their makeshift offices, a “dirty apartment” in Palo Alto. ..... Its early gains were the result of laborious word-of-mouth marketing, with Silbermann leaning on everyone in his network to spread the word and personally contacting several thousand users to quiz them about what they liked and disliked. “If he hadn’t done that, my guess is we would’ve given up in a few more months,” says Sharp, 31. “It’s kind of ridiculous how long we worked on it, given how little success we were seeing.” .......... Nor was it an overnight sensation with investors. “He had a hell of a time raising money in the beginning,” says Ron Conway, a perpetual member of the Forbes Midas List, whose firm, SV Angel, invested in April 2011 at the urging of fellow angel Shana Fisher. Yelp CEO Jeremy Stoppelman was one of those who failed to see the potential. “A friend sent it to me, and I didn’t even take the meeting,” he recalls. “I was like, ‘Ehhhh, this is interesting, but I don’t know what to do with it. It’s too conceptual for me.’ ” ...... To date, Pinterest has raised $764 million in seven rounds from a group of investors that includes FirstMark Capital, Andreessen Horowitz and Bessemer Venture Partners. In May it closed that blockbuster $200 million round that provided fuel for its international expansion. At that valuation–and given the mania for fast-growth companies over the ensuing six months, a raise in the range of $8 billion to $10 billion is possible–Silbermann’s estimated 15% stake and Sharp’s estimated 10% would make them, on paper, candidates for the FORBES billionaires list. ........ “ I spend a lot more of my time trying to clearly communicate where we’re going so everyone can march in the same direction,” Silbermann says. “Technology has made it easier for small teams to scale fast, but no one’s ever released something that makes it easy to build a culture proportionately as fast.” ...... “My mind is like a warren, whereas Ben’s is like a f–king database.” ..... the phases of the so-called purchase funnel: awareness, consideration, preference and purchase. ...... More than 90% of Pinterest usage is on mobile, higher than Facebook (68%) and Twitter (86%) ...... Every Promoted Pin has to start out as an ordinary pin, living on the partner’s boards, and stunts like price promotions and contests are off-limits. ..... “How do we do for discovery what Google did for search?” Silbermann muses. “How do we show you the things you’re going to love even if you didn’t know what you were looking for? We think if we answer that question, all the other parts of the business will follow.”
Okay, so the metric is revenue per user. I can see Pinterest going past Facebook on that.

Ben Silbermann On How Pinterest Slowly Grew To Massive Scale
In June 2010, more than two years after Ben Silbermann left his job to start what became Pinterest, and three months after launching, the site had 3,000 registered accounts.

Net Neutrality: A Counter Viewpoint


Net neutrality to me is obvious. I don't want the Internet to go the way of cable television. Expanding capacity is how you respond to an increase in traffic load.

But it is okay to listen to a counter viewpoint.

The Right Way to Fix the Internet
Letting go of an obsession with net neutrality could free technologists to make online services even better. ..... the Internet never has been entirely neutral. Wireless networks, for example, have been built for many years with features that help identify users whose weak connections are impairing the network with slow traffic and incessant requests for dropped packets to be resent. Carriers’ technology assures that such users’ access is rapidly constrained, so that one person’s bad connection doesn’t create a traffic jam for everyone. ..... It costs more to get online in the United States than just about anywhere else in the developed world ..... U.S. service is sometimes twice as expensive as what’s available in Europe—and slower, too. ...... the Internet arose in an ad hoc fashion; there is no Internet constitution to cite. ..... their equivalent of the Federalist Papers: a 1981 article by computer scientists Jerome Saltzer, David Reed, and David Clark. The authors’ ambitions for that paper (“End-to-End Arguments in System Design”) had been modest: to lay out technical reasons why tasks such as error correction should be performed at the edges, or end points, of the network—where the users are—rather than at the core. In other words, ISPs should operate “dumb pipes” that merely pass traffic along. This paper took on a remarkable second life as the Internet grew. In his 2000 book Code, a discussion of how to regulate the Internet, Harvard law professor Lawrence Lessig said the lack of centralized control embodied in the 1981 end-to-end principle was “one of the most important reasons that the Internet produced the innovation and growth that it has enjoyed.” ...... “unavoidable vagueness” about the dividing line between allowable network-management decisions and impermissible bias. .. The line remains as blurry as ever, which is one reason the debate over net neutrality is so intense. ......... if profit-hungry companies are left unfettered to choose how to handle various types of traffic, they “will continue to change the internal structure of the Internet in ways that are good for them, but not necessarily for the rest of us.” ........ codifying too many overarching principles for the Internet makes many engineers uncomfortable. In their view, the network is a constant work in progress, requiring endless pragmatism. Its backbone is constantly being torn apart and rebuilt. The best means of connecting various networks with one another are always in flux. ......... “You can’t change congestion by passing net neutrality or doing that kind of thing,” says Tom Leighton, cofounder and chief executive of Akamai Technologies. .. To keep traffic humming online, Leighton says, “you’re going to need technology.” ........ A central tenet of net neutrality is that “best efforts” should be applied equally when transmitting every packet moving through the Internet, regardless of who the sender, recipient, or carriers might be. But that principle merely freezes the setup of the Internet as it existed nearly a quarter-century ago, says Michael Katz, an economist at the University of California, Berkeley, who has worked for the FCC and consulted for Verizon. “You can say that every bit is a bit,” Katz adds, “but every bitstream isn’t the same bitstream.” Video and voice transmissions are highly vulnerable to errors, delays, and packet loss. Data transmissions can survive rougher handling. If some consumers want their Internet connections to deliver ultrahigh-resolution movies with perfect fidelity, those people would be better served, Katz argues, by more flexible arrangements that might indeed prioritize video. Efficiency might be more desirable than a strict adherence to equity for all bits. ......... For many years, high-volume sites run by Facebook, YouTube, Apple, and the like have been negotiating arrangements with many companies that ferry data to your Internet service provider—backbone operators, transit providers, and content delivery networks—to ensure that the most popular content is distributed as smoothly as possible. Often, this means paying a company such as Akamai to stash copies of highly in-demand content on multiple servers all over the world, so that a stampede for World Cup highlights creates as little strain as possible on the overall Internet..................... Netflix last year was accounting for as much as one-third of all U.S. Internet traffic on Friday evenings. .... In the short term, Netflix resolved the problem by paying for more of the peering points that carriers such as Comcast and Verizon required. More strategically, Netflix is arranging to put its servers in Internet service providers’ facilities, providing them with easier access to its content. ....... the Netflix fight shouldn’t distract regulators who are trying to figure out the best way to keep the Internet open. They should be focusing, he says, on making sure that everyday customers are getting high-speed Internet as cheaply and reliably as possible, and that small-time publishers of Internet content can distribute their work. .... A tiny video startup doesn’t generate enough volume to force Comcast to install extra peering points. ........ “zero rating,” in which consumers are allowed to try certain applications without incurring any bandwidth-usage charges. The app providers usually pay the wireless carriers to offer that access as a way of building up their market share in a hurry... In much of Africa, people with limited usage plans can enjoy free access to Facebook or Wikipedia this way. ......... In the United States, T-Mobile lets customers tap into a half-dozen music sites, such as Pandora and Spotify, without incurring usage charges. ...... When Tim Wu talked about net neutrality a decade ago, he framed it as a way of ensuring maximum competition on the Internet. But in the current debate, that rationale is in danger of being coƶpted into a protectionist defense of the status quo. If there’s anything the Internet’s evolution has taught us, it’s that innovation comes rapidly, and in unexpected ways. We need a net neutrality strategy that prevents the big Internet service providers from abusing their power—but still allows them to optimize the Internet for the next wave of innovation and efficiency.

Going Head To Head With Carbon

Negatives emissions feel counter intuitive. Why not capture the carbon right where it is emitted? Would that not be cheaper?

Can Sucking CO2 Out of the Atmosphere Really Work?
air capture, which means, essentially, scrubbing it from the sky. ..... As emissions have accelerated—they’re now rising at 2 percent per year, twice as rapidly as they did in the last three decades of the 20th century—scientists have begun to recognize the urgency of achieving so-called “negative emissions.” ..... “Once capturing carbon from the air is profitable, people acting in their own self-interest will make it happen” ...... In the winter of 2008 Eisenberger sequestered himself in a quiet house with big glass windows overlooking the ocean in Mendocino County, California. There he studied existing literature on capturing carbon and made a key decision. ...... a 40-foot-high tower of fans, steel, and silver tubes ..“It’s doing exactly what the tree is doing,” says Eisenberger. But then he corrects himself. “Well, actually, it’s doing it a lot better.” ....... “There’s really little chance that you could capture CO2 from ambient air more cheaply than from a coal plant, where the flue gas is 300 times more concentrated” ...... deriving fuels from biomass—which removes CO2 from the atmosphere as it grows. As that feedstock is fermented in a reactor to create ethanol, it produces a stream of pure carbon dioxide that can be captured and stored underground ...... scientific advances made in air capture will eventually be used primarily on coal and gas power plants.
