self-driving car that struck and killed a pedestrian in March 2018 had serious software flaws, including
the inability to recognize jaywalkers, according to the NTSB. The US safety agency said
that Uber's software failed to recognize the 49-year-old victim, Elaine
Herzberg, as a pedestrian crossing the street. It didn't calculate that it
could potentially collide with her until 1.2 seconds before impact, at which
point it was too late to brake.
surprisingly, the NTSB said Uber's system design "did not include a
consideration for jaywalking pedestrians." On top of that, the car
initiated a one second braking delay so that the vehicle could calculate an
alternative path or let the safety driver take control. (Uber has since
eliminated that function in a software update.)
Although the [system] detected
the pedestrian nearly six seconds before impact ... it never classified her as
a pedestrian, because she was crossing at a location without a crosswalk [and]
the system design did not include a consideration for jaywalking pedestrians.
autonomous test vehicles may have failed to identify roadway hazards in at
least two other cases, according to the report. In one case, a vehicle struck a
bicycle lane post that had bent into a roadway. In another, a safety driver was
forced to take control to avoid an oncoming vehicle and ended up striking a
parked car. In the seven months prior to the fatal crash, Uber vehicles were
involved in 37 accidents, including 33 in which other vehicles struck the Uber
resumed testing in December 2018, it used significantly revised software.
According to the NTSB, Uber did a simulation of the new system using sensor
data from the fatal Arizona accident. It determined that it would have detected
the pedestrian 289 feet before impact and had four seconds to brake before
impact at a speed of 43.2 mph. The average stopping distance for a human is
about 130 feet at that speed, including reaction time, so it seems likely that
the vehicle would have been able to stop in that distance.
will meet on November 19 to determine the cause of the accident that occurred
in Tempe, Arizona in March of 2018. Prosecutors have already absolved Uber of
criminal liability, but are still weighing criminal charges against the driver.
World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 · A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling. “You barely feel that the patient is 3,000 kilometers away,” he said.
Visualizing The Power Of The World's Supercomputers BY TYLER DURDEN FRIDAY, JAN 21, 2022 - 04:15 AM A supercomputer is a machine that is built to handle billions, if not trillions of calculations at once. Each supercomputer is actually made up of many individual computers (known as nodes) that work together in parallel. A common metric for measuring the performance of these machines is flops , or floating point operations per second . In this visualization, Visual Capitalist's Marcus Lu uses November 2021 data from TOP500 to visualize the computing power of the world’s top five supercomputers. For added context, a number of modern consumer devices were included in the comparison. Ranking by Teraflops Because supercomputers can achieve over one quadrillion flops, and consumer devices are much less powerful, we’ve used teraflops as our comparison metric. 1 teraflop = 1,000,000,000,000 (1 trillion) flops. Supercomputer Fugaku was completed in March 202
Beijing Orders Alibaba To Dump Media Assets That Rival China's Propaganda Machine BY TYLER DURDEN MONDAY, MAR 15, 2021 - 07:30 PM Beijing is reviving its crackdown on the country's biggest tech firms, reminding the world that the CCP is still focused on neutralizing any and all threats to its control of the Chinese economy and its people. Even after amending China's official ideology to include entrepreneurs among the protected classes represented by the CCP (in addition to workers, farmers and soldiers), Beijing, with President Xi at its center, has apparently decided that Chinese tech firms won't follow the American model after all. Instead, their growth and competitive capabilities will be curtailed for the sake of stability at home. After Tencent was censured and strict new requirements were officailly imposed on Alibaba-owned Ant Group that will prevent the company from growing , the Wall Street Journal reports that next up on Beijing's to-do lis
