Within hours of the school shooting in Broward County, Florida, computer experts discovered pro and anti-gun control tweets that appear to be linked to Russian bots.A bot is a computer program written to execute a series of commands that can, for example, post many tweets across many accounts nearly instantly.Some posts discovered by computer experts, and highlighted in stories on tech websites and The New York Times, were pro-gun control. Others were in support of gun rights. Experts familiar with the M.O. of other countries' fake tweets say taking sides isn't the point."I think disruption is really what they are going for. I think anytime that you can throw doubt or cast doubt and chaos into -- not just a nation -- but an ideological structure," said Sam Jay, a Metropolitan State University of Denver professor of Rhetoric.Jay said countries who post fake tweets in numbers such as those seen after the shooting in Florida like it when Americans are confused."Then it's quite easier to manipulate a much larger decision-making process such as elections," Jay said.Twitter found and removed thousands of fake accounts after the 2016 presidential election, the company said. Facebook turned over some 3,000 fake ads to Congress."So essentially what any person can do, a program (bot) can do. And of course the programs can do it so much more rapidly and have a much wider spread," said MSU Denver Computer Science professor Steve Beaty.Bots were also active during the controversy surrounding NFL players taking a knee during the national anthem to protest police brutality.Bots posted tweets using opposing hash tags like #boycottnfl or #takeaknee.Beaty said computer science researchers estimate 10 percent of tweets posted are not from real people or don't contain real information.On the low end, it’s estimated 6,000 tweets are sent every second. That works out to half a billion a day.Doing the math means there are more than 51 million fake tweets every day "A Twitter bot won't go through a web page. It won't actually go through Twitter's own application. It will go directly to the software behind Twitter," Beaty said.Beaty said determining what is a fake tweet or a tweet from an account that isn't a real person isn't impossible."See what else they posted. See how long they've been on. Often these Twitter bots have been on for a very short amount of time. They've been on for a day or two and then all of a sudden they've sent out a million things," he said.It is against Twitter and Facebook's policy to create fake accounts and both companies have pledged to crack down.Twitter said on Wednesday it was implementing additional changes.Twitter will ban users from simultaneously posting "identical or substantially similar content to multiple accounts."Users also will not be allowed to like, retweet or follow from several accounts at the same time, the company said. 2938

YOSEMITE NATIONAL PARK, Calif. (AP) — A hiker in Yosemite National Park fell to her death while climbing to the top of the iconic granite cliffs of Half Dome, where cables are installed each summer.Park spokesman Scott Gediman says 29-year-old Danielle Burnett, of Lake Havasu City, Arizona, was scaling the steepest part of the trail Thursday when she fell more than 500 feet (150 meters) down the rocky terrain.Gediman says Burnett was dead when Park Rangers arrived on the scene.Rangers install the cables to assist the climbs of thousands of hikers who make the popular 14-mile (22-kilometer) round trip to the top of the 8,800-foot (2,670-meter) rock face.Gediman says the incident remains under investigation. 723

at Oslo Middle School, there are computers, and most of the basic supplies are here. But the beanbag chairs and carpet?"All the people that provided money for that project were my friends and family," Henley said.It's Henley's way of creating a home away from home."Think of it as decorating your home to make it comfortable. I want this to be my kids home," Henley said.Now in her fourth year of teaching, Henley spent 0 of her own money on things ranging from supplies to snacks, that aren't just rewards for good behavior."We made DNA models with Twizzlers," she said. "The kids like it, and we have a lot more fun that way. They're a lot more likely to learn it when we're using food and hands-on type things to learn."Henley is not alone reaching into her own pocket.A study by the National Center of Education Statistics showed 94 percent of public school teachers spent money on supplies without reimbursement. The average amount? 0.Henley turned to Twitter for help. #Clearthelists was started by a teacher in Texas as a way to get the community involved.Henley created her wish list on Amazon."It blew up a little because Royal Caribbean purchased a few items off of my list," Henley said.Beyond the teachers, many schools are starting to address the high cost of supplies for their students. This year at Oslo Middle School 'they're only asking kids to have one binder with tab dividers."They have all their assignments in one binder. it helps them to organize," Asst. Principal Chris Cummings said.This story was originally published by Jon Shainman on 1572
