WASHINGTON, D.C. -- IBM says it is getting out of the facial recognition business over concern about how it can be used for mass surveillance and racial profiling.A letter to U.S. lawmakers Monday from new IBM CEO Arvind Krishna said the tech giant “has sunset its general purpose facial recognition and analysis software products.”Krishna’s letter called for police reforms and said “IBM firmly opposes and will not condone uses of any technology, including facial recognition technology offered by other vendors, for mass surveillance, racial profiling” and human rights violations.Krishna was addressing Democrats who recently introduced police reform legislation in Congress in response to the death of George Floyd and others in law enforcement interactions that have sparked a worldwide reckoning over racial injustice.IBM had previously tested its facial recognition software in New York City.In the letter, Krishna also called for a “national dialogue” on whether and how facial recognition should be employed by domestic law enforcement agencies.“Artificial Intelligence is a powerful tool that can help law enforcement keep citizens safe,” wrote Krishna. “But vendors and users of Al systems have a shared responsibility to ensure that Al is tested for bias, particularity when used in law enforcement, and that such bias testing is audited and reported.” 1373

We're about a month into the school year and teachers are struggling to keep children up to speed amid the pandemic.We spoke with a principal at an elementary school in Arizona who says students are about five to six months behind. Some kids who should be reading by now, simply are not.She says when you think about it, most students have not been inside a classroom since March.One challenge for teachers has been teaching at-home students and giving one-on-one attention to those in the classroom. The other challenge has been technology.“It’s day to day, whether or not technology works,” said principal Sarah Lewis. “And if you think about it, we've been hybrid for about three weeks now, but before that, we were all digital learning. We would have full days where we wouldn't have any technology, so basically we would have to tell the kids, go into Google Classroom and practice your multiplication facts.”Lewis says it's tough to hear young kids are learning on their parents’ cell phones, because they don't have a computer.However, she says she's proud of how fast teachers became tech savvy, as well as the level of understanding from most parents and their willingness to be flexible. She's also proud of the kids.“Five-year-olds do not understand that you cannot go over to your friend’s desk and ask what they're reading or coloring, but as far as wearing the mask and being OK when we ask them to step away or ask them to, I mean it's incredible that little kids are able to do it,” said Lewis.Lewis says she wants people to know just how difficult it is for teachers to balance teaching online students and those in the classroom. She says many are fearful of the pandemic, but realize they have a job to do. 1733

  

WASHINGTON, D.C. - You may have gotten one in the mail or a knock on the door: for months, the Census Bureau has counted every person living in the United States.Even the homeless in a rural state like Montana get counted."In the last month, we finished and submitted a census for 70 homeless people," said Carley Tuss, with St. Vincent de Paul homeless services in Great Falls, Montana.This year, though, an accurate census count could be in jeopardy."The census is not a dry statistical exercise," said Thomas Wolf of the Brennan Center for Justice, pushing in court for an accurate census count.Because of the coronavirus, the Census Bureau extended the deadline for in-person counting, setting it for the end of October. Then, things changed."Suddenly, then, on August 3, the Commerce Department and the Census Bureau abruptly and without explanation said that they were going to go back to the original timeline," Wolf said.The Census Bureau now plans to stop counting at the end of September, a full month earlier than planned.What's more, the deadline for processing those tens of millions of census responses, set for the spring of next year, got pushed up to the end of this year.However, a federal judge temporarily halted the plan, until there can be a court hearing later this month."If you cut the time short, you don't have enough time to collect the data. You don't have enough time to process the data," Wolf said, "and then you end up with real problems."Those problems could include under-counting communities of color, like African Americans, Hispanics, and Native Americans.In response to our questions, the Census Bureau referred us to a statement from their director, Steven Dillingham, which says, in part, "We are taking steps and adapting our operations to make sure everyone is counted while keeping everyone safe."Census maps, which are updated continuously, show that it can be a struggle in some states.Montana, Arizona, Alabama, Georgia, and New Mexico rank at the bottom of the list, with only about three-quarters of households responding.That can end up costing those states billions of dollars for highways, food stamps, school programs, and student loans.For example, Florida had one of the country's worst response rates during the 2010 census, and it cost the state tens of billions in federal dollars."When we don't participate, the money goes elsewhere," said Jonathan Evans, the city manager of Riviera Beach, Florida.In the meantime, multiple federal court cases are challenging – among other things-- the census schedule and the Trump administration's effort to exclude undocumented migrants from the count.Whether those cases are resolved before the census count ends remains to be seen. 2738

  

WATCH THE LAUNCH:(KGTV and CNN) - Friday morning's launch of a SpaceX rocket from the Central California coast will be a notable one for Elon Musk's out-of-orbit efforts.A Falcon 9 rocket is scheduled to blast off from Vandenberg Air Force Base at 7:13 a.m. PT. The rocket will deliver a group of satellites for communications firm Iridium (IRDM).Shortly after launch, SpaceX is probably going to make another experimental attempt to guide the rocket's nose cone, also called a payload fairing, onto a passenger ship outfitted with a giant net.PHOTOS: SpaceX?rocket launch visible above San DiegoThe fairing rests on the very top part of the rocket, and it acts as a shield for satellites during launch. Once the rocket is in space, the fairing splits into two and falls away. Typically, it's left to plummet back to Earth where the ocean becomes its graveyard.But SpaceX wants to change that, mostly because the fairing on its Falcon 9 costs million.As Musk once put it, if "you had million in cash on a palette flying through the air, and it's going to smash into the ocean, would you try to recover it? Yes. Yes, you would."The company has quietly attempted to recapture the 43-foot-long fairing halves since at least March of 2017.At least twice, SpaceX has guided fairing halves to soft landings in the ocean, according to Musk's social media pages.But there's a problem."Once it gets into the water, it's quite damaging to the electronics and components inside the fairing," said Glenn Lightsey, a professor of aerospace engineering at Georgia Tech. "Most likely if it gets into the water, it's not usable."Enter, Mr. Steven.For Friday's launch a ship, named Mr. Steven, will head out to sea and attempt to catch half of the fairing with a giant net. 1810
