This video continues our look at Colonizing Space by examining the idea of Asteroid Mining and setting up colonies on Asteroids. We explore the science as well as practical issues of engineering, economics, legality, and psychology of such distant outposts.
arstechnica looks at Breakthrough Starshot, the goal to send a spaceship to the nearest star at 20% the speed of light. While this would mean we'd reach the star in our lifetime — we'd reach Alpha Centauri in 20 years — travelling at those speeds mean that impact with a stray atom or — worse a dust particle, would have some catastrophic results.
Dust presents a somewhat different problem. Small dust particles will essentially act like a simultaneous bombardment by a lot of gas atoms. That's because the energy binding things together in a dust particle is tiny compared to the energy of the collision itself, and the dust is largely composed of heavier atoms. But a sufficiently large dust particle will create a collision energetic enough to destroy a craft. And "sufficiently large" isn't very big; the authors estimate that it only has to…
You've probably heard by now about that weird star located between the Cygnus and Lyra constellations that not only has been steadily dimming for the last 100 years, but also emitting unusual patterns of light dips. Well, if you'd like a good read chockful of theories involving extraterrestrials, Brian Wang of Next Big Future takes you from incomplete Dyson spheres all the way to giant mirrors for solar-powered propulsion of sail-equipped starships.
Stopping at the destination can be done using a smaller ‘drouge shoot’ mirror-sail deployed out the back of the starship. Meanwhile, he original sail in front would be released, but the reflected annular beam from it would strike the deceleration sail and the starship slows. This would require an optically controlled original sail.
The primary ‘deflect and direct’ mirrors need to be positioned‘near’ the star’s surface and kept stationary relative to the sky…

On Make, Damon McMillan talks about his self-navigating solar-powered boat which travelled 2,400 miles by itself from California all the way to Hawaii.
Indeed, the idea of this tiny, homemade boat surviving 2,400 miles of open ocean to reach Hawaii seems foolishly unrealistic, and I know that more than anybody else. With help from friends, I built the eight-foot-long, autonomous, foam-and-fiberglass, solar-powered SeaCharger in my garage – not to make money or to win a contest, but simply as a challenge. And a challenge it was. What started out as a year-long project turned into 30 months of mistakes, compromises, and start-overs. So for the next couple of hours, I spend my time worrying and fretting, glued to the screen of my phone, waiting for each telemetry report sent by SeaCharger’s satellite modem. When it becomes obvious that the…
With a broken heart, but not ready to give up yet, Mathias Ritter shares with us a video of their 19 feet tall free-standing domino tower which collapsed on its own after 7-hours of work they were only 10 layers away from reaching the status of second tallest in the world. Still, despite the many expletives that must have been said out loud, it is a pretty impressive collapse. We featured the Austrian Domino Art in their last two record breaking events.144More
Ranging in price between $1,700 USD and $2,200 USD, Taybles are beautiful coffee tables that look like old school cassette tapes. The price may seem excessive, but the last time I saw something like this, it was going for close to $5,000 USD. Yikes.
The TAYBLES started a few years ago as a mere dream of Taylor’s. “As a kid, I grew up with a tape player in my car listening to Dad's old cassettes like Rolling Stones and Cheap Trick." Excited to work in a new medium, Taylor set to work on making the TAYBLES prototype in his closet sized workshop at the apartment he managed in Los Angeles. “I would often work late at night, and would worry about my tenants complaining about noise.” After completing the prototype Taylor and Justin realized what a fantastic product…
If you like having a dog but don't like picking up after it, the Pooperapp has this figured out for you: after your dog has done its business, tap the location on the app and someone else comes and picks it up for you. So while you're driving for Uber, you can help make ends meet by doing this on the side. What will the digital economy think of next?
Scoopers are people like you – dog lovers who want to improve the streets and communities we live in. Anyone with a smart phone can scoop for us. Scoopers are paid per-scoop, use their own mode of transportation – car, bike, scooter, hiking boots – and scoop on their own schedule. See why people are signing up everyday to come pick up dog poop with us.
According to Aaron Frank of the SingularityHUB, the technology the world depends on in order to function has become so complex that even experts are dumbfounded when things stop working.
[...] In the case of driverless cars, machine learning systems build their own algorithms to teach themselves — and in the process become too complex to reverse engineer.
And it’s not just software that’s become unknowable to individual experts, says Arbesman.
Machines like particle accelerators and Boeing airplanes have millions of individual parts and miles of internal wiring. Even a technology like the U.S. Constitution, which began as an elegantly simple operating system, has grown to include a collection of federal laws “22 million words long with 80,000 connections between one section and another.”
In the face of increasing complexity, experts are ever more likely to be taken by surprise when systems behave in unpredictable and unexpected ways.
In this video, Real Engineering explains the financial reasons that will allow Elon Musk's SpaceX to successfully bring people to Mars. One of the key factors: building everything it needs and using as little energy as possible.471 More
According to Motherboard, company Taser International plans on having footage recorded by a police officer's bodycam sent back for facial recognition analysis, allowing them to know if anyone that has walked by is connected to an active warrant.
“With body cameras, that entire structure is completely gone,” Garvie said. “Instead of having a particularized interaction—again, in the future, assuming the technological capabilities are there—this is not particularized at all. It’s essentially running a search on everybody walking past a given officer on his patrol. There’s no notice given to these people, and there’s certainly no consent. And there’s no police interaction even in place. No probable cause for a search.”
She continued: “All of a sudden, the simple act of walking past a police officer becomes a law enforcement interaction.”
The Superbook is defined as a shell that, once plugged with your phone, gives you a full fledged laptop. This means an actual keyboard, touch gestures, a large screen, and plenty of battery power.
At its core, the Superbook is a smart laptop shell that provides a large screen, keyboard and multi-touch trackpad, 8+ hours of battery, and phone charging capabilities.
When plugged into your Android smartphone, it launches our app to deliver the full laptop experience.
Think of it as the ultimate accessory for your smartphone.
Cool, I guess; however, if I am going to carry around a shell that looks like a laptop, I may as well carry an actual netbook with an OS I have a modicum of control over.373 More

Already guilty of manipulating the mood of users, censorship, news feed manipulation and removing content, Berit Anderson of Scout theorises on how just two people working for the social media giant could impact results of the upcoming U.S. elections simply by altering what the news feed would show.
There is no process that we are aware of within Facebook for understanding the political, ideological and societal effects news feed updates might have on users.
That means that, assuming their code is error-free and doesn’t negatively impact privacy, engagement, or business metrics, two employees could collude to manipulate the beliefs and behavior of Facebook’s 1.65 billion users without anyone—users, fellow employees, executive leadership, Mark himself—even noticing.
One reported Facebook employee implied in a 2011 post that Mark Zuckerberg reviews all changes to Newsfeed algorithms. Facebook has yet to confirm or deny that fact to Scout.…
