How ad-free subscriptions could solve Facebook

At the core of Facebook’s “well-being” problem is that its business is directly coupled with total time spent on its apps. The more hours you pass on the social network, the more ads you see and click, the more money it earns. That puts its plan to make using Facebook healthier at odds with its finances, restricting how far it’s willing to go to protect us from the harms of over use. The advertising-supported model comes with some big benefits, though. Facebook CEO Mark Zuckerberg has repeatedly said that “We will always keep Facebook a free service for everyone.” Ads lets Facebook remain free for those who don’t want to pay, and more importantly, for those around the world who couldn’t afford to. Ads pay for Facebook to keep the lights on, research and develop new technologies, and profit handsomely in a way that attracts top talent and further investment. More affluent users with more buying power in markets like the US, UK, and Canada command higher ad prices, effectively...

The CC Aurora is actually pretty fun, as far as projectors go

I don’t review projectors. Projectors are boring. Even the good ones. They remind me of vacation slideshows and the film strips we had to watch in health class — neither of which I’m in a particular hurry to revisit in my adult life. That said, I’ve always harbored some germ of a notion that some day I might buy one, to compensate for being one of those weirdos without a TV set. There’s something undeniably appealing about a big screen TV you can break out during movie night and then stash back into the closest of your one-bedroom New York City apartment. XGIMI’s CC Aurora is the closest I’ve seen to fitting the bill — or, for that matter, being a projector that I could actually muster any reasonable amount of excitement about. From the looks of it, it’s kind of the perfect package for the apartment dweller: it’s compact, self-contained with a built-in speaker system and plays nicely with mobile devices. Clearly I’m not alone here, either. The product scored $170,000 on Indi...

Airbnb will open its Cuba listings to users outside the United States

Airbnb will now let travelers from outside the U.S. to book properties in Cuba after receiving authorization from the U.S. government, reports the Associated Press . Previously, only Americans were allowed to reserve the site’s Cuban listings . They will open to international users on April 2. Airbnb launched its Cuban operations in April 2014 , four months after the Obama administration revealed that it will begin to restore diplomatic relations with the Communist country . The historic policy change means that travel and trade sanctions will be lifted , which is expected to boost tourism to Cuba dramatically because Americans no longer need licenses to visit. In fact, President Obama is currently on an official visit to Cuba , the first president since Calvin Coolidge to do so. According to the AP, Cuba is currently Airbnb’s fastest-growing market, with about 4,000 homes added since it opened listings. Other travel businesses...

Here’s how to keep track of Elon Musk’s Roadster and Starman in space

Elon Musk’s Starman, the mannequin driver of the Tesla Roadster SpaceX launched aboard its Falcon Heavy rocket, is taking a trip around our solar system, in a large elliptical orbit that will bring him relatively close to Mars, the Sun and other heavenly bodies. But how to track the trip, now that the Roadster’s onboard batteries are out of juice and no longer transmitting live footage? Thanks to the work of Ben Pearson, a SpaceX fan and electrical engineer working in the aerospace industry, who created ‘Where is Roadster,’ a website that makes use of JPL Horizons data to track the progress of the Roadster and Starman through space, and to predict its path and let you know when it’ll come close to meeting up with various planets and the Sun. The website tells you the Roadster’s current position, too, as well as its speed and whether it’s moving towards or away from Earth and Mars at any given moment. It’s not officially affiliated with SpaceX or Tesla, but it is something Elon...

Engineering against all odds, or how NYC’s subway will get wireless in the tunnels

Never ask a wireless engineer working on the NYC subway system “What can go wrong?” Flooding, ice, brake dust, and power outages relentlessly attack the network components. Rats — many, many rats — can eat power and fiber optic cables and bring down the whole system. Humans are no different, as their curiosity or malice strikes a blow against wireless hardware (literally and metaphorically). Serverless software deployment to the cloud, this is not. New York City officially got wireless service in every underground subway station a little more than a year ago, and I was curious what work went into the buildout of this system as well as how it will expand in the future. That curiosity is part of a series of articles I’ve written on an observed pattern known as cost disease, the massively inflating costs of basic human services like health care, housing, infrastructure, and education. The United States spends trillions of dollars on each of these fields, massively outspending sim...
