Death On Hole 9: Finally, A Jetpack Golf Cart

jetpack-golf-cart.jpg

This is the jetpack golf cart created for pro golfer Bubba Watson by Oakley (of cool shades fame). It’s not actually a real jetpack though, it’s actually two ducted fans powered by a 200-horsepower gas engine. There is no jet power. That sucks too because jet power is one of my favorite powers besides x-ray vision and the ability to read minds. I know exactly what you’re thinking now, and, I’m going to be honest, it really hurts my feelings. Nice nipples though.

Keep going for a video of the cart not being flown by anybody but professionals. Also, how convenient they never actually let you hear audio of the personal tornado.

Thanks to Jan, who’s always dreamed of yelling ‘Fore!" and throwing golf balls at players from above.

Bubble Zoom in Google Play Books is the Best Way to Read Digital Comics

Introduced at the best time, given this week is SDCC, Google Play Books is getting a new feature exclusively for those who enjoy reading comic books on digital devices such as tablets and smartphones. Called Bubble Zoom, this feature intelligently recognizes text bubbles inside of digital comics, allowing users to follow a storyline more interactively. It gives off the sense that the comic is alive, making the act of reading a bit more fun.

To get this feature working, all a reader must do is tap on the screen and the text bubbles will follow along with your taps. It’s not automated, so you don’t need to worry about the bubbles going too fast. 

According to Google, Bubble Zoom will be made available on the latest version of Play Books for Android as a technical preview with all Marvel and DC collected volumes supported. To celebrate the launch, Google is hosting a 50% sale on select DC and Marvel comics, too. Use the code SDCC2016 at checkout by July 24 to take advantage.

Looking forward, Google’s hope is to bring Bubble Zoom to every single comic and manga title they offer.

To get a sense of what this Bubble Zoom feature looks like, check it out below. Pretty cool, right?

After Rare Event, 2 Earth-sized Exoplanets Are Looking More Habitable

TRAPPIST-1

TRAPPIST-1 may well be one of the closest stars to look for life in our own backyard, thanks to three planets in its habitable zone.

Now, we’re one step closer to understanding if those planets could hold life, thanks to a new study published today in Nature.

Using data gathered from the Hubble Space Telescope, researchers at MIT witnessed two occultation events from the innermost planets, TRAPPIST-1b and 1c. The two had near-simultaneous transit events on May 4, 2016 just 12 minutes apart, and some spectrum was gathered from the transit.

Through this, the MIT team made the first atmospheric observation of an Earth-mass planet, and determined the atmosphere of both planets lacked a “gas envelope” of hydrogen and helium around them.

That means that the planets don’t belong to a strange class of planets called gas dwarfs, which is exactly what it sounds like: a mini-mini-Jupiter. They often are terrestrial planets enveloped in a thick atmosphere with a similar composition to Saturn or Jupiter.

“If they were to have such an atmosphere, then they would not be habitable,” says Julien de Wit, lead author of the study and an MIT postdoc. He coauthored the paper announcing the initial discovery of TRAPPIST-1’s system in a May Nature paper.

By ruling out the gas dwarf scenario, the researchers can now home in on more specific details of these two planets. This includes determining if they have atmospheres that are dense and Venus-like or filled with water vapor, which would place them as more Earth-like. There’s also the possibility that, like Mercury, the planets lack anything more than an incredibly thin exosphere.

Some of the really detailed observations of the system, which is is just 39 light years away from Earth, will have to wait for the 2018 launch of the James Webb Space Telescope, which will characterize the atmospheres of Earth-like planets in detail.

In the meantime, de Wit and colleagues will have to rely on data from Hubble, which can still be used to to determine key characteristics like the presence of water or methane. While they might not get as lucky as a two-for-one transit next time, it still could reveal if TRAPPIST-1’s planets contain the ingredients for life.

“What occurred on May 4 was a very rare event,” says de Wit.

Facebook Plans to Beam Internet to Backwaters with Lasers

Engineers from Facebook’s Connectivity Lab have published details of a new optical technology to help laser beams deliver fast Internet access to remote areas.

Lasers are an attractive way to send data over significant distances. Not only can they hold a lot of information and propagate a long way, they also don’t require dedicated spectrum like cellular networks, which means they can be used to set up ad hoc data links to off-grid locations. And because they use line-of-sight light transmission, more than one can be used in the same area without interference.

In order to achieve high data rates, though, the detectors used to catch the light signals have to be small. Problem is, as a beam of light propagates through space, it becomes wider—in fact, orders of magnitude wider than the detector itself. While it’s possible to focus the light back down using optics, it’s complex and expensive. Instead, engineers from the Connectivity Lab have developed a system that neatly gets around the problem.

The fluorescent optical fibers absorb blue laser light and re-emit it as green, focusing it toward a small photodetector in the process.

Writing in the journal Optica, the engineers describe how they’ve used fluorescent materials, instead of traditional optics, to collect light from data-carrying laser beams. A series of plastic optical fibers, doped with organic dye molecules that absorb blue light and re-emit it as green light, are shaped into an almost-sphere. When a laser signal hits the fibers, they emit green light within two nanoseconds. The light travels down the length of the fibers and is ultimately directed toward a small—and fast—photodetector.

So far the system can be used to receive signals carrying data at rates of up to 2.1 gigabits per second, though the team claims it could go faster if it were built to absorb infrared, rather than blue, light.

It’s worth pointing out that this isn’t the first piece of hardware to emerge from the Connectivity Lab. Famously, it’s been working on a solar-powered drone to deliver Internet access. That particular project is progressing slowly, though, so despite the fact that the team behind the new laser device plans to test it in a real-world setting, there’s likely still much development ahead before it’s used widely.

The social network is, however, busy pursuing plenty of other projects to take data to the sticks. Most notably, its Telecom Infra Project will use open-source cellular networks to achieve similar results. That way, you see, anyone will be able to sign up on Facebook.

Fastest-ever production drone is also one of the smartest

As a rule, the fastest drones tend to be either prototypes or one-off homebrew models. Even the quickest off-the-shelf drones are pokey in comparison. Teal, however, doesn’t think you should have to compromise. It’s launching a namesake drone that it claims is the world’s fastest production drone. At 70MPH, it’s so fast that it could outrun cars on the highway… within its maximum 2-mile range and 20-minute flight time (using a high-endurance pack), anyway. And no, it’s not as dangerous as it sounds. The Teal drone is stable in high winds (up to 40MPH in testing), touts high-accuracy GPS and comes with multiple modes to accommodate rookie pilots.

Crucially, this isn’t meant as a one-trick pony. On top of a 13-megapixel, 4K-capable camera, Teal packs NVIDIA’s Tegra TX1 (a beefy processor for a drone) and a software platform that encourages third-party apps. If you can imagine a flight mode, you can probably implement it. There are built-in apps for command and control flying, racing and a follow mode like you see on some camera drones. Also, Teal promises support for future modules that add radar-guided avoidance, thermal imaging and vision-based positioning.

If you suspect that this no-compromise design won’t come cheap, you’re right. It’ll cost you $1,299 to pre-order now, although you will get the high-endurance battery if you make your move before August 15th. Should everything go according to plan, early orders will arrive by the holidays. That’s a lot to pay and a long time to wait. Look at it this way, though: a DJI Phantom 4 officially sets you back $1,399, and it flies at ‘just’ 45MPH. While it does last longer at 28 minutes of air time, Teal may be the better buy if you’re a thrill junkie, a budding programmer or both.

When Police Come Near, BB Guns Look All Too Real

Twelve-year-old Mannie Thames knows a lot of kids with BB guns. He says kids have them for safety and because they’re cool.

“Sometimes people get bullied a lot, and they want to have something to protect their self,” Thames says. “And sometimes people think it’s cool, they want to shoot people for fun.”

He explains this in between bites of snacks at the after school center, Penn North Kids Safe Zone, in West Baltimore.

Replica guns that shoot BBs and other projectiles are popular with kids. But in some settings, they pose a special danger.

Twelve-year-old Tamir Rice had an air pellet gun that looked like a handgun when he was shot and killed by Cleveland police in 2014. Earlier this year, after a 150-yard chase, Baltimore police shot 14-year-old Dedric Colvin, who had a BB gun that looked like a real pistol.

That teenager survived, but it drew new attention to what can happen when kids in high crime areas carry what look like real guns.

Thames’ mother had strong words for him about guns, telling him not to play with them because they are bad for him and could get him killed.

But Thames admits that he has bought BB guns in the past.

Since he heard about the boy who was shot, however, “I’m not going to buy one never in my life no more.”

Asia Moss, a middle-schooler, says she was shot with a BB when she was younger. She says the kids who are toughest have BB guns, pocket knives or mace.

“They use it for protection, but some of them just use it to be fun and they use it to harm other people and think it’s fun,” Moss says.

BB guns have sparked discussion among parents.

Kim Shelton of East Baltimore says her son was used to playing with them. She’s tried to change that, but a few months ago she saw her 11-year-old playing on the street with a BB gun.

“I was looking outside my window,” Shelton remembers. “And I ran downstairs and I said to him, ‘Please, I don’t ever want to see you playing with guns ever again,’ because to me it looked a real gun. I was hysterical.”

Federal law requires toy guns to have a colored cap to show they’re not firearms. But BB guns, a type of air pellet gun, don’t have that requirement.

In Baltimore City it’s illegal for a minor to possess a BB gun. Still, state lawmakers are trying ban the sale of so-called “imitation firearms” altogether.

T.J. Smith of the city’s police department says you have to consider the environment: In high crime neighborhoods, officers often need to make decisions in seconds.

“When you have a realistic looking gun that is down to the T and the only thing and the only way you know that it’s different is by staring down the barrel of it, that sometimes is going to be too late,” Smith says.

He points to several arrests where police have recovered a mix of actual firearms and replica guns, and to a case where a suspect was carrying a real rifle that was pink.

“We’re not talking about young people or adults that are going out to shoot a barrel of hay on several acres of land,” he says. “We’re talking about in environments where we see crime, and where we see crime involving handguns.”

Joe Murfin, a spokesperson for Daisy — the manufacturer that made the BB gun carried by Colvin — says they come with warnings that adult supervision is required and that misuse of BB guns could cause serious injury or death.

“We also warn people not to brandish an air gun in public, that people may misunderstand what this is and it could be a crime,” Murfin says.

Still, those warnings can feel disconnected from inner city realities.

Ericka Alston, who directs youth services at the Penn North Kids Safe Zone, even bans water guns.

“In West Baltimore: absolutely not. Not here,” Alston says. “Not under my watch, because regardless if pink bubbles are coming out or green slime, kids will shoot to kill. It’s still a gun.”

She says it’s also another way to teach kids that guns — whether they’re real or not — and gun violence don’t have to be part of their communities.
