• How Emotion Tracking Startups Lightwave and Affectiva Are Turning Mind-Reading Into a Reality

    These entrepreneurs are racing to claim a new tech frontier : your emotions. Deep in the bowels of Houston’s 72,000-seat NRG Stadium, in a curtained-off makeshift room near the court where the Villanova Wildcats and the University of North Carolina Tarheels are playing for the NCAA basketball championship, a small team of engineers and data scientists from a company called Lightwave huddles over laptops watching a stream of real-time data. But the engineers aren’t looking at shooting (...)

  • Clubhouse Is Recording Your Conversations. That’s Not Even Its Worst Privacy Problem

    The popular new social media platform is scooping up more data than you might think. Clubhouse was sort of perfectly made for the pandemic. People aren’t going out, and they’re desperately searching for social connections and entertainment. The app provides both in a way, while also capitalizing on the draw of celebrity influencers on the platform. It’s also built on one of the most effective strategies for generating buzz and excitement—scarcity. In order to join Clubhouse, you have to have (...)

    After Inc. published this story in 2015, new outside reporting emerged in 2020 indicating that, as a juvenile, Damien Patton was affiliated with a hate group and pleaded guilty to a drive-by shooting at a synagogue. In response, Patton has said, "I did terrible things and said despicable and hateful things, including to my own Jewish mother, that today I find indefensibly wrong, and feel extreme remorse for.

  • How Couchsurfing became the Friendster of the sharing economy – Gigaom

    Voilà un article intelligent avec plein de commentaires utiles.

    Before there was Uber, Lyft, or Airbnb, there was Couchsurfing. For a certain sect of millennials — say, those entering college between 2005 and 2011 — Couchsurfing was transformative. Members all over the globe offered up their couches for free to these cash-strapped travelers.

    It was the original sharing economy, except there was a lot more “sharing” in Couchsurfing’s version than there was “economy.” And that was the problem.

    Without a way to properly support itself, the application staggered under the burden of its popularity. It nearly went out of business because of technical problems, and its community struggled to maintain its values with the flood of new users. Raising venture funding just exacerbated the problem, triggering power struggles between long time volunteers and new leadership.

    Couchsurfing learned the hard way that “sharing” doesn’t scale easily. Can an organization founded on cooperation sustain itself in a capitalist world?

    Ask the CEO: Revenue at Couchsurfing – Couchsurfing Blog

    January 19, 2015

    When people ask me how Couchsurfing will make money, my answer is pretty simple: we’ll experiment with well-understood monetization models to see what works best for the community and the company. Experimenting means we’ll test, iterate and learn.

    Couchsurfing’s revenue, at present, comes from its Verification service. Members have been asking for a long time about our plans for monetization. The answer wasn’t very illuminating but it was the truth: until now, we hadn’t been particularly focused on monetization.

    The conversion to a for-profit corporation was objected to by many members.[26][37][38] Founder Casey Fenton said he received 1,500 emails in the days after announcing the conversion.[1] Even though the founders did not receive any cash from the financing,[39] members were opposed to the founders having a valuable ownership interest in an organization that was financed by donations and built using volunteer work.[26][34] The company spent more than $10,000 on a public relations firm to educate its directors on how to respond to the press about the conversion to a for-profit entity. A 3-page letter was sent to over 1,000 volunteers.[

  • KLM Has a Surprising Request for Passengers: Don’t Fly

    It sounds noble, but what’s the real motive?

    If your company is in business to make money (as pretty much all companies are), how likely are you to launch a huge marketing campaign begging people not to use your product? Probably not very likely. Unless you’re #KLM Royal Dutch Airlines, in which case you’ve already done it.

    That’s right. KLM, the Netherlands’ national airline, just launched a campaign called “#Fly_Responsibly” in which it makes a surprising request of its customers: Fly less. “Do you always have to meet face-to-face?” the promotional video asks. “Could you take the train instead?”

    Wait, what? An airline is asking its passengers not to fly? Yes. Because, as KLM explains in an accompanying statement, air travel accounts for 2 to 3 percent of manmade CO2 emissions worldwide and that number is growing, as more people in more countries are climbing out of poverty and hankering to see the world. The 100-year-old airline says it’s been doing its part. In an accompanying statement, KLM says it has been replacing its fleet with more fuel-efficient planes, using sustainable fuel, and has even created a sustainable fuel plant in the Netherlands. “We work hard to get things right, but all parties involved need to join forces to create a sustainable future.”

    Some critics say this amounts to nothing more than “greenwashing.” After all, the airline still offers special deals and its website invites people to “Book a flight with KLM and visit the most incredible destinations around the world.” And indeed, in the accompanying statement, the airline explains that it won’t stop promoting air travel—after all it wants to stay in business “for our customers and for our 33,000 employees.”
    No carbon tax, please.

    Interestingly, the airline also notes in its statement that it’s opposed to a national carbon tax in the Netherlands since, it claims, passengers would simply drive to Germany or Belgium and fly from there instead. Therefore, KLM says, a carbon tax on aviation should only be imposed if it can be imposed globally—which is pretty disingenuous, because of course that’ll never happen. It also claims that a tax that isn’t invested back into the aviation industry to make it more sustainable “won’t do anything to combat climate change.” This, again, is untrue because the main point of a carbon tax is to make polluting more expensive, which causes people and companies to do less of it.

    All this talk about a carbon tax can give you a big clue as to KLM’s true motivation here. A carbon tax or cap-and-trade law seems like a non-starter in the U.S.—even in the very blue state of Washington, one was roundly defeated last election. But in Europe, the idea is very much alive. France’s huge “yellow vest” demonstrations began as opposition to a planned carbon tax that working people felt they couldn’t afford. (It was withdrawn.) But in the Netherlands, a carbon tax which would increase the price of airline tickets among many other things is in the works. My guess is that KLM hopes that by getting out ahead on this issue, it can push the government toward letting companies take voluntary action rather than writing new laws.

    KLM also says that as part of its sustainability effort it’s sharing information about sustainability with other airlines, beginning in September with a webinar with its sustainable fuel supplier, SkyNRG. Which sounds good, but since SkyNRG is in the business of selling its fuel, the webinar may amount to a big sales pitch. Perhaps more useful, though, KLM says it’s exploring connections with trains. That’s a great idea, because for a lot of passengers, transferring to a train rather than a connecting flight to go a relatively short distance will be appealing, and environmentalists believe short airplane trips in particular can and should be replaced with other forms of transportation. KLM has also been inviting passengers to pay a small extra fee that the airline will use to offset their flight and make their travel carbon neutral. It will share that system with other airlines as well.

    KLM’s motivations may not be as pure as it claims but the fact remains that the airline is taking some positive steps toward reducing its own environmental impact. For that, we should all applaud. And then do what the airline suggested and fly a little bit less.

  • Harvard Just Discovered that PowerPoint is Worse Than Useless | Inc.com

    Intuitively, we all know that PowerPoint is a horrible time-suck. (Admit it: don’t you groan inside when the first slide pops up?) And anecdotally, the world’s top entrepreneurs (like Jeff Bezos, Jack Dorsey and Mark Cuban) avoid it like the proverbial plague.

    At least two peer-reviewed studies buttress the anecdotes.

    A study conducted at the University of New South Wales in 2007 by John Sweller (the psychologist who invented Cognitive Load Theory) found that showing audiences the same words that are being spoken reduces, rather than increases, audience comprehension.

    In other words, when you throw up bullet points and then run through them, you’re guaranteeing that whatever you say will be quickly forgotten. Not because you’re bloody boring, but because people can’t read and listen at the same time.

    The entire concept of PowerPoint is apparently misbegotten, according to a recent Harvard study cited in Forbes, which found that

    “PowerPoint was rated (by online audiences) as no better than verbal presentations with no visual aids. (Ouch.)”

    Consider that for a second. You audience will be just as happy with your presentation if you do it without your slides. Which means the time you spent building the deck was basically wasted.

      The Cognitive Style of Powerpoint: Pitching Out Corrupts Within
      In corporate and government bureaucracies, the standard method for making a presentation is to talk about a list of points organized onto slides projected up on the wall. For many years, overhead projectors lit up transparencies, and slide projectors showed high-resolution 35mm slides. Now “slideware” computer programs for presentations are nearly everywhere. Early in the 21st century, several hundred million copies of Microsoft PowerPoint were turning out trillions of slides each year.

      Alas, slideware often reduces the analytical quality of presentations. In particular, the popular PowerPoint templates (ready-made designs) usually weaken verbal and spatial reasoning, and almost always corrupt statistical analysis. What is the problem with PowerPoint? And how can we improve our presentations?

  • Inside ProtectWise, the Futuristic Startup That Ran Cybersecurity for the Super Bowl | Inc.com

    “Most cybersecurity systems have the same interface as the cable modem in your house,” he says. “That needed to change.”

    ProtectWise, which Chasin co-founded in 2014 in Denver with former McAfee exec Gene Stevens, completely reimagines the way cybersecurity software looks. Instead of staring at pie charts and seemingly infinite strings of characters, you’re presented with something much more visual: a three-dimensional cityscape. Your company’s entire network is laid out in front of you, and you can easily detect and observe abnormal behavior in real time—or rewind to see when and how an attack occurred.

    To create the company’s futuristic interface, Chasin recruited Jake Sargeant, a Hollywood designer who has worked on visual effects for CGI-intensive films like Tron: Legacy and Terminator Salvation.
