amid the coronavirus outbreak."This is necessary to slow the spread of COVID-19, and builds on our previous public health recommendations," San Francisco Mayor London Breed said on Twitter when making the announcement.While the Warriors are still planning on hosting tomorrow's home game against the Brooklyn Nets, they plan to do so without fans in attendance, 364

a law that would allow President Donald Trump to use the military break up protests and riots within U.S. cities.Speaking at a press conference Wednesday, Esper said he believes the National Guard is better equipped to handle situations in the United States to help local law enforcement."I say this not only as Secretary of Defense, but also as a former soldier and a former member of the National Guard, the option to use active-duty forces in a law enforcement role should only be used as a matter of last resort and only in the most urgent and dire of situations," Esper said. "We are not in one of those situations now. I do not support invoking the Insurrection Act."On Monday, 686

- one of a series of treaties that the Central Powers signed after their defeat in World War I - outlined the dissolution of the Ottoman Empire and called for an autonomous Kurdistan.Three years later, after the end of the war, Western allies dropped demands for an independent Kurdish state and the Kurdish region was divided among several countries.What does Turkey have to say?Turkish President Recep Tayyip Erdogan has always adopted a robust attitude against Kurdish nationalism. The President made it clear that his ultimate goal is to 543

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

One resident in Sarpy County, Nebraska, reported several drones flying in unison last week."Most interesting part is that the drones were flying in the night. People don't know what they are doing there. No feedback from federal agencies, local government and no one really knows what's going on there," said Victor Huang, an assistant professor at the Aviation Institute at the University of Nebraska Omaha.Drones are complex and extremely advanced. They can be used for for film making, emergency services and agricultural monitoring."The drone, similar to our computer systems, it can really do a lot of things. To me, the only limitation is your imagination," Huang said.But no one, not even the Federal Aviation Administration, knows what these drones are doing except that they're flying in a pattern, they're large and there's many of them."They don't know if it's illegal or not because right now there's no way of knowing what is up there," KMTV pilot Justin Enos said.Based on flight patterns and altitude, experts believe it could be some sort of agricultural monitoring. Regardless, the fact that no one can account for them is frightening residents. Some have even talked about shooting the drones down, but that's not a good idea. The mystery drones are reportedly up to six feet in length. If the drones happen to weigh more than 55 pounds, they technically could be considered to be aircraft."If that's a legal registered drone, if you shoot it down, you are essentially shooting an aircraft down. So that is definitely illegal," Huang said."Registered or not, it's going to be dangerous. The batteries on these things are very flammable," Enos said.Enos believes if it's agricultural information the people behind the drones are after, the general public shouldn't be too worried."I think people are concerned, especially people that aren't familiar with drones and the technology," Enos said.The Nebraska State Patrol tweeted Monday that they are working with several sheriff's offices, local police departments and federal authorities to figure out who is behind the drone activity.The FAA has also stated they are aware of the sightings and are investigating.This story was originally published 2217
