For years, big tech companies have used huge salaries, bonuses and stock packages to lure artificial #intelligence experts out of #academia....
The talent shift could accelerate the development of artificial intelligence inside tech giants like #Google, #Microsoft, #Amazon and #Apple.#news #capitalism #economy #education #University #money #science
But at the universities the professors left, graduating students were less likely to create new A.I. companies. When they did, they attracted smaller amounts of funding, according to the study. The effect was most pronounced in the field of “deep learning,” a #technology that has become a crucial part of new A.I. systems.
On July 23rd, a tiny spacecraft in orbit around Earth unfurled a thin sheet of mylar that’s the area of a boxing ring. The result is a reflective sail that rides not on wind, but on light from the Sun to propel the vehicle through space.#PlanetarySociety #LightSail #Technology #Exploration #Light #Propulsion
Over the course of the next month, LightSail 2 will perform something of a dance in orbit, twisting its sail back and forth to ride on sunlight. As it approaches the Sun, the spacecraft will keep its sail edge on toward the light. Then, once it’s directly in front of the Sun, it will twist and face the sail toward the Sun. “It’ll work very much like a sailboat, where you push, twist, and pack into the ‘wind,’” Nye said. “And then you twist and take advantage of sailing ‘downwind.’” If all goes well, the sunlight will push on LightSail 2, and the spacecraft’s orbit will rise slightly as it whips around the Earth.
Eventually, this orbit raising will lead to the spacecraft’s demise. LightSail 2 will only be able to raise its orbit on one side of the Earth, and each time the orbit gets higher on that side, the orbit gets lower on the other. In about a year, LightSail 2 will pass close enough to Earth that it will be dragged into the planet’s atmosphere, burning up during its descent.
However, its fiery demise won’t be a tragedy since LightSail 2 is only intended to prove that this type of in-space propulsion can work. If it manages to do that, The Planetary Society plans to share its solar sail technique with other spacecraft developers that are looking for innovative ways to maneuver vehicles through space. A solar sail could be used for something as simple as maintaining a spacecraft’s position in orbit, or it could be amplified for something as complex as sending cargo to Mars.
Tribot looks like a tiny circuit board because that's what it largely is, but there are some significant additions to the circuitry. One is a small lithium polymer battery, which means all the power for its motions and circuits are carried on board. The motions are powered by what's called a shape-memory alloy, which can be deformed at one temperature but snap back into place once the temperature is changed. Flexible hinges and a polymer core allow these "muscles" to move any of the three legs either gradually or with a sudden snap, all enabled by tiny heaters embedded in the hardware.#Robots #Robotics #Technology
Another interesting feature of the robot is its construction. The circuit board and polymer are originally made as a flat, triangular unit. A couple of folds are all that's needed to convert this shape into the Tribot's trefoil design.
The robot represents a significant advance, given that previous attempts at building robots that could move via different mechanisms involved simply having the robot carry different hardware for each mode of movement. But perhaps just as surprising is that the tiny circuitry contains everything needed for the robots to cooperate to perform tasks.
Opening up a laptop like HP’s EliteBook 840 G6, EliteBook x360 830 G5, EliteBook x360 830 G6, or a convertible tablet like the Elite x2 G4—it’s almost too much.#Tablets #Laptops #Repair #Maintenance #Technology #Engineering
Keep in mind as you scan these images and read this praise: these are not your uncle’s business laptop. These utterly serviceable laptops are not much thicker than a miserably scoring MacBook. The 840 G6 is 0.71 inches (1.8 cm) high when closed, or 0.12 inches (0.31 cm) thicker than the latest MacBook Pro. Only one of these devices requires liquid solvent and more than an hour to change the battery.
Using only one slightly specialized screwdriver, a T8 Torx, we managed to remove the keyboard, trackpad, pointing stick, display, fingerprint sensor, card reader, battery—we could go on. What’s important about those parts are that they’re the parts that are most likely to wear out or malfunction. Being able to replace those without damaging any other part of the device, and get it closed again, is a core tenet of building a responsible, repairable device. It’s a big part of why the EliteBook 840 G6 earned a 10 out of 10 on our repairability scale."
Even though we’re still in alpha phase, yesterday we got contacted by Facebook’s lawyers in regards to the word “book” in our name.#socialmedia #technology #Facebook #openbook
