Amazon Prime day, in just four years, has grown to a two-day extravaganza that now almost rivals Black Friday.However, it's a day where the very best deals are on Amazon-branded products, or products tied in with Amazon (such as the Ring doorbell and video camera system). For instance, you will find a few great TV deals, but nothing to the extent you find in November.In addition, deals change every hour, making it very difficult to pre-plan your shopping. You need to keep checking prices, or set price alerts on the items you want most.So with the help of 573

Amy Klobuchar is ending her Democratic presidential campaign and is set to endorse Joe Biden. Her campaign says she is flying to Dallas and plans to join Biden at his rally Monday night. The Minnesota senator is the third presidential candidate to drop out of the race in less than 48 hours, following Pete Buttigieg’s departure on Sunday and Tom Steyer's exit on Saturday. Their decisions reflect an urgent push among moderates to consolidate behind Biden as a counter to progressive rival Bernie Sanders.Klobuchar outlasted several better-known and better-funded Democrats, thanks to a better-than-expected third-place finish in in New Hampshire. But she couldn't turn that into success elsewhere.Sanders continues to lead all candidates with 60 pledged delegates. Klobuchar picked up seven delegates in the first four states. 840

A second Florida city paid thousands of dollars to ransomware attackers who hacked their computer systems -- the latest in a growing trend that forces local governments offline.Officials from Lake City agreed Tuesday to pay 42 bitcoin, roughly 6,000, to hackers who seized the city's computer systems June 10, ending a 15-day standoff.It's the second city in Florida to fall prey to ransomware attackers this summer: On June 19, Riviera Beach officials voted to pay their requested ransom of 65 bitcoin, close to 0,000, to hackers who disabled the city's online services in late May.Lake City police said the city paid a ,000 deductible to its insurance company, which will cover the rest of the ransom.In a statement, the city called the attack a "triple threat," a ransomware program that attacked the city's network three different ways and took out email systems, landline phones and online credit card payment.Cyber attacks on government are growingRansomware attacks have spiked since 2016, hijacking the computer systems of government entities like cities, police departments and schools. It's a unique type of cyberattack: Hackers encrypt all files on the systems and demand payment, usually in bitcoin, to restore them.Ahead of attacks on Lake City and Riviera Beach, there were at least 22 reported breaches of public sector networks in 2019, CNN reported in May.Populous cities like Baltimore, Albany and Atlanta have all combated ransomware attacks that forced them to perform municipal services manually.Complete recovery of a city's systems can take up to several weeks and cost cities millions more than the agreed ransom -- a combined cyberattack on Atlanta and Newark cost more than million in damages.Lake City officials did not return multiple requests for comment.The-CNN-Wire? & ? 2019 Cable News Network, Inc., a Time Warner Company.

More evacuations may be issued.The fire erupted the same day that California's largest utility started 571

Although scientists study space every day, what’s been difficult learning more about "deep space." But there's one company helping NASA and the U.S. Air Force go where no satellite has gone before."Deep space" is well outside the Earth's atmosphere, lying beyond the Earth-moon solar system. It's also known as "interstellar space." Deep space is a mystery to a lot of scientists. NASA's Voyager spacecraft that was launched in 2011 reached the edge of our solar system.Many scientists are wanting to make their way past Jupiter to learn even more, but there are limitations in the space engine technology today. A company called Roccor, based in Longmont, Colorado, is doing their best to change that.“We are just getting in a contract with NASA to do solar sailing where we are going to leave earths orbital realm and go much farther away,” said Bruce Davis, who works for Roccor.Davis and his team are working on a project called the "solar cruiser."They created what’s called a "solar sail." It essentially gets attached to a spacecraft and acts as a propeller, ultimately upping its performance by pushing it farther into deep space.“We are capturing whatever is coming off the sun — that’s radiation, that’s photons — we call it a collective pressure," Davis said. "That’s what we are trying to grab to give ourselves propulsion.”When the sail opens up, it’s as big as an office building. Right now, they are only in creation mode, but they hope to have it done soon. 1490
