A new Xbox controller designed for people with disabilities has been announced by Microsoft today. The Xbox Adaptive Controller features two large programmable buttons and 19 jacks that can be connected to a range of joysticks, buttons, and switches to make it easier for a wider range of people to play games on Xbox One and Windows 10 PCs. The Verge reports: "I can customize how I interface with the Xbox Adaptive Controller to whatever I want," says Solomon Romney, a Microsoft Store learning specialist who was born without fingers on his left hand. "If I want to play a game entirely with my feet, I can. I can make the controls fit my body, my desires, and I can change them anytime I want. You plug in whatever you want and go. It takes virtually no time to set it up and use it. It could not be simpler."
The focus is on connectivity and customizability, with players able to build a setup that works for their capabilities and needs. It won't be an all-in-one solution for many games, but through the use of peripherals and the Xbox's system-level button remapping, the possibilities could be endless. The Xbox Adaptive Controller will cost $99.99 and goes on sale later this year.
Steve Guttenberg, writing for CNET: It's a funny thing, the ongoing turntable sales surge shows no signs of slowing down, but nearly all new music is recorded digitally. It seems like a contradiction, turntables and LPs are purely analog in nature, but nearly all new (not remastered LPs) made over the last 30+ years were recorded, mixed, and mastered from digital sources. Older, pre 1980 LPs were made in an all-analog world. Today's LPs are hybrids of a sort, the grooves are still analog, but the music was probably made in the digital domain. |
Be that as it may, LPs, regardless of vintage, can sound great. While pre-1980s records may be richer in tone and warmth, there are lots of more recent albums that sound just as good or better. In other words vinyl's sound quality or lack thereof has mostly to do with the quality of the original recording, and the choices made by the recording, mixing, and mastering engineers.
Despite the overwhelming number of digital recordings, there is still a tiny percentage of all-analog recordings being made. To cite one mostly analog studio, the legendary Electrical Audio, which owner Steve Albini told me records and mixes around 70 percent of all of its sessions on tape.
S810 writes: The European Space Agency (ESA) has released a treasure trove of data from its Gaia Spacecraft; totaling around 1.7 billion stars. This star map is the largest of its kind to date. In addition to the star map, the data also contains motion and color data of 1.3 billion stars relative to the Sun. Furthermore, it includes "radial velocities, amount of dust, and surface temperatures of lots of stars, and a catalogue of over 14,000 Solar System objects, including asteroids," reports Gizmodo. You can view the data here, and view a guide for what the data contains and how to use it here.|
An anonymous reader quotes a report from Pitchfork: In 2016, a European patent filing described a way of manufacturing records that the inventors claimed would have higher audio fidelity, louder volume, and longer playing times than conventional LPs. Now, the Austrian-based startup Rebeat Innovation has received $4.8 million in funding for the initiative, founder and CEO Gunter Loibl told Pitchfork. Thanks to the investment, the first "HD vinyl" albums could hit stores as early as 2019, Loibl said. The HD vinyl process involves converting audio digitally to a 3D topographic map. Lasers are then used to inscribe the map onto the "stamper," the part that stamps the grooves into the vinyl. According to Loibl, these methods allow for records to be made more precisely and with less loss of audio information. The results, he said, are vinyl LPs that can have up to 30 percent more playing time, 30 percent more amplitude, and overall more faithful sound reproduction. The technique would also avoid the chemicals that play a role in traditional vinyl manufacturing. Plus, the new-school HD vinyl LPs would still play on ordinary record players.|
A large crack, stretching several miles, made a sudden appearance recently in south-western Kenya. The tear emerged after heavy rains caused havoc in the nation last month, which also saw neighborhood get flooded and major highways closing off. The downpour also exposed a fault line that geologists now say is evidence that the African continent will split into two over the next tens of millions of years. From a report: The Earth is an ever-changing planet, even though in some respects change might be almost unnoticeable to us. Plate tectonics is a good example of this. But every now and again something dramatic happens and leads to renewed questions about the African continent splitting in two. The Earth's lithosphere (formed by the crust and the upper part of the mantle) is broken up into a number of tectonic plates. These plates are not static, but move relative to each other at varying speeds, "gliding" over a viscous asthenosphere. |
[...] The East African Rift Valley stretches over 3,000km from the Gulf of Aden in the north towards Zimbabwe in the south, splitting the African plate into two unequal parts: the Somali and Nubian plates. Activity along the eastern branch of the rift valley, running along Ethiopia, Kenya and Tanzania, became evident when the large crack suddenly appeared in south-western Kenya. When the lithosphere is subject to a horizontal extensional force it will stretch, becoming thinner. Eventually, it will rupture, leading to the formation of a rift valley. This process is accompanied by surface manifestations along the rift valley in the form of volcanism and seismic activity. Rifts are the initial stage of a continental break-up and, if successful, can lead to the formation of a new ocean basin.
cold fjord writes: Chinese space authorities say the defunct Tiangong 1 space station mostly burned up on re-entry into the atmosphere over the central South Pacific. The China Manned Space Engineering Office said the experimental space laboratory re-entered around 8:15 a.m. Monday. Scientists monitoring the craft's disintegrating orbit had forecast the craft would mostly burn up and would pose only the slightest of risks to people. Analysis from the Beijing Aerospace Control Center showed it had mostly burned up. Launched in 2011, Tiangong 1 was China's first space station, serving as an experimental platform for bigger projects, such as the Tiangong 2 launched in September 2016 and a future permanent Chinese space station. Two crews of Chinese astronauts lived on the station while testing docking procedures and other operations. Its last crew departed in 2013 and contact with it was cut in 2016. |
An anonymous reader quotes a report from Quartz: [A] pair of studies by the U.S. National Toxicology Program found "clear evidence" that exposure to radiation caused heart tumors in male rats, and found "some evidence" that it caused tumors in the brains of male rats. (Both are positive results; the NTP uses the labels "clear evidence," "some evidence," "equivocal evidence" and "no evidence" when making conclusions.) Tumors were found in the hearts of female rats, too, but they didn't rise to the level of statistical significance and the results were labeled "equivocal;" in other words, the researchers couldn't be sure the radiation is what caused the tumors. The next scientific step will be to determine what this means for humans. The peer-reviewed papers will be passed on to the U.S. Food and Drug Administration, which is responsible for determining human risk and issuing any guidelines to the public, and the Federal Communications Commission, which develops safety standards for cell phones. The FDA was part of the group of federal agencies who commissioned the studies back in the early 2000s.
Ronald Melnick, the NTP senior toxicologist who designed the studies (and who retired from the agency in 2009), says it's unlikely any future study could conclude with certainty that there is no risk to humans from cell phone use. "I can't see proof of a negative ever arising from future studies," Melnick says. He believes the FDA should put out guidance based on the results of the rat studies. "I would think it would be irresponsible to not put out indications to the public," Melnick says. "Maintain a distance from this device from your children. Don't sleep with your phone near your head. Use wired headsets. This would be something that the agencies could do right now." Quartz notes that when the draft results were published earlier this year, all the results were labeled "equivocal," meaning the study authors felt the data weren't clear enough to determine if the radiation caused the health effects or not. "But the panel of peer reviewers (among them brain and heart pathologists, toxicologists, biostaticians, and engineers) re-evaluated the data and upgraded several of the conclusions to 'some evidence' and 'clear evidence.'"
New Scientist: The most recognisable scientist of our age, Hawking holds an iconic status. [...] He was routinely consulted for oracular pronouncements on everything from time travel and alien life to Middle Eastern politics and nefarious robots. He had an endearing sense of humour and a daredevil attitude -- relatable human traits that, combined with his seemingly superhuman mind, made Hawking eminently marketable. |
But his cultural status -- amplified by his disability and the media storm it invoked -- often overshadowed his scientific legacy. That's a shame for the man who discovered what might prove to be the key clue to the theory of everything, advanced our understanding of space and time, helped shape the course of physics for the last four decades and whose insight continues to drive progress in fundamental physics today. The New York Times: 1970 Dr. Hawking shows that the area of a black hole's event horizon -- a spherical surface marking the point of no return -- can only increase, never decrease, as stuff falls into a black hole or it collides and merges with other black holes.
1971 He suggests that mini black holes much smaller than stars created in the Big Bang could be peppering the universe.
1974 He shocks his colleagues and the world by showing that black holes will leak and explode when quantum effects -- the weird laws that describe subatomic behavior -- are taken into account.
1976 Dr. Hawking says exploding black holes add randomness and unpredictability to the universe, forever erasing information about what might have fallen into a black hole.
Quantum physicists object, saying the universe can't forget, initiating a 40-year argument about the fate of information. Dr. Hawking concedes in 2004, but does not say how information is preserved in a black hole, and the argument continues to this day.
1982 Using a mathematical conceit called imaginary time, Dr. Hawking and James Hartle, a theoretical physicist at the University of California, Santa Barbara, propose a model of a self-contained universe that has no boundary in space or time, and thus no place or time when the laws of physics break down.

New submitter stikves writes: The Raspberry foundation has launched an incremental update to the Raspberry Pi 3 model B: Raspberry Pi 3 Model B+ . In addition to slight increase (200MHz) in CPU speed, and upgraded networking (802.11ac and Gigabit, albeit over USB2), one big advantage is the better thermal management which allows sustained performance over longer load periods.
