The sparrows fled the courtyard. It was quiet amid the classics. John Szabo stepped out of the elevator and walked through the sunlit atrium of the Central Library. He passed a slumbering homeless man and, with the efficiency of a spy, disappeared into stacks of bound archives, hundreds of thousands of relevant and obscure pages -- including the 1991 "Journal of the American Chamber of Commerce in Japan." A tall man with sparks of gray in his goatee, Szabo, the city librarian, oversees 72 branches, a $241.8 million budget, 17,000 restaurant menus, 64 ukuleles, a Shakespeare volume from 1685, and lockers of puppets for a children's theater. He stopped at a shelf holding years of "Family Handyman" magazines. Founded in 1951 for those who grout tile and hang cabinets, the periodical was no match for Prince Harry's memoir or a Stephen King novel.

Answer: Hardware and software vary by manufacturer and operator. Flight management computers use very complex software to perform a myriad of tasks. The interface is improving with airplanes such as the Boeing 787 and Airbus A350.

The man killed in a crash while using the autopilot function of a Tesla Model S electric vehicle posted a YouTube video a month before the fatal crash showing the technology saving him from another collision and wrote that he was "very impressed." I have done a lot of testing with the sensors in the car and the software capabilities," Joshua Brown, 40, of Canton, Ohio, wrote on April 5 in comments posted with the 41-second video. "I have always been impressed with the car, but I had not tested the car's side collision avoidance," he said. Then on May 7, Brown, a former Navy Seal, was killed when his Tesla crashed into a tractor trailer in Williston, Fla. Federal regulators said Thursday they had opened an investigation into the fatality, thought to be the first in the auto industry involving an autonomous driving feature. The National Highway Traffic Safety Administration said its Office of Defects Investigation was conducting a preliminary evaluation of the autopilot function. The agency is expected to issue guidelines for autonomous vehicles this month. Automakers do not need to have autonomous driving functions approved by NHTSA but must certify their vehicles meet safety standards. Calling Brown's death "a tragic loss," Tesla said it was the first-known fatality involving its autopilot feature. The technology, which is in public beta testing and must be activated by the driver, has been used in 130 million miles of driving without a fatality, the company said. The crash took place at 3:40 p.m. May 7 on U.S. Route 27A during clear and dry conditions, according to the accident report from the Florida Highway Patrol. Brown's vehicle was headed east when a tractor trailer driven by Frank Baressi of Palm Harbor, Fla., traveling in the opposite direction, made a left turn onto a side street. The Tesla's roof hit the underside of the tractor trailer. The car skidded under the truck and off the road, plowing through two wire fences before crashing into a utility pole, the accident report said. Baressi told the Associated Press that Brown was "playing'Harry Potter' on the TV screen" in the car when the crash took place. Kim Montes, a spokeswoman for the Florida Highway Patrol, told The Times that a portable DVD player was found in the Tesla but said she did not know whether it had been in use. "At the time of the impact, we don't know what the status of that DVD player was.

In this image from video, Frank Baressi speaks during an interview with The Associated Press at his home in Palm Harbor, Fla. Thursday, June 30, 2016. Baressi, 62, was the driver of the truck that was hit by a Tesla that Joshua D. Brown, of Canton, Ohio, was operating in self-driving mode, and who was killed in the May 7 accident in Williston, Fla. Baressi said the driver was "playing Harry Potter on the TV screen" at the time of the crash and driving so quickly that "he went so fast through my trailer I didn't see him."

The U.S. announced Thursday the first fatality of a wreck involving a car in self-driving mode, the 40-year-old owner of a technology company who nicknamed his vehicle "Tessy" and had praised its sophisticated "Autopilot" system just one month earlier for preventing a collision on an interstate. The government said it is investigating the design and performance of the system aboard the Tesla Model S sedan. Joshua D. Brown, 40, of Canton, Ohio, died in the accident May 7 in Williston, Florida, when his car's cameras failed to distinguish the white side of a turning tractor-trailer from a brightly lit sky and didn't automatically activate its brakes, according to government records obtained Thursday. Frank Baressi, 62, the driver of the truck and owner of Okemah Express LLC, said the Tesla driver was "playing Harry Potter on the TV screen" at the time of the crash and driving so quickly that "he went so fast through my trailer I didn't see him." "It was still playing when he died and snapped a telephone pole a quarter mile down the road," Baressi told The Associated Press in an interview from his home in Palm Harbor, Florida.
