Twitter CEO Jack Dorsey knows the tech world has a problem. He's asking big questions like "How do we earn peoples' trust?""We realize that more and more people have fear of companies like ours," Dorsey said in an in-depth interview with CNN. He cited the "perceived power that companies like ours have over how they live and even think every single day."The following day, President Trump proved his point."Social Media is totally discriminating against Republican/Conservative voices. Speaking loudly and clearly for the Trump Administration, we won't let that happen," the president tweeted Saturday morning.Trump is tapping into a widely held belief on the right about biased tech companies. The claims have even become an issue on the campaign trail. "They are trying to silence us" is the new rallying cry.Companies like Facebook and Twitter say they understand the perception, but deny that their algorithms and employees discriminate against any particular political point of view."Are we doing something according to political ideology or viewpoints? We are not. Period," Dorsey said Friday. "We do not look at content with regards to political viewpoint or ideology. We look at behavior."But he knows some people do not believe him."I think we need to constantly show that we are not adding our own bias, which I fully admit is left, is more left-leaning," Dorsey said."We need to remove all bias from how we act and our policies and our enforcement and our tools," he added.In the interview, Dorsey kept coming back to the need for transparency, in much the same way that journalists talk about trying to explain news media processes to readers. Tech companies, he said, need to explain themselves too."I'll fully admit that I haven't done enough of that," he said. "I haven't done enough of, like, articulating my own personal objectives with this service and my own personal objectives in the world."Dorsey spoke candidly about the "fear" people feel about Silicon Valley.When asked "Do you feel as powerful as they think you are?" Dorsey said no, "but I do understand the sentiment. I do understand how actions by us could generate more fear, and I think the only way we can disarm that is by being a lot more open, explaining in a straightforward way why we make decisions, how we make decisions."His bottom line: "We need to be reflective of the service that we're trying to build."Trump, of course, is one of Twitter's highest-profile users. His Saturday morning tweets about censorship lined up closely with Tucker Carlson's Friday night segment titled "Coordinated censorship by big tech." Carlson cited the recent actions against far-right conspiracy theorist Alex Jones."Increasingly the people in charge use technology to silence criticism, mostly of them," Carlson said.To hear Carlson and other conservative commentators tell it, Twitter and its peers are quashing dissent on a daily basis.Trump tweeted that "they are closing down the opinions of many people on the RIGHT, while at the same time doing nothing to others."Trump did not mention Jones or Twitter specifically. But Jones has been in the news lately because CNN and other outlets have been highlighting how his social media posts violated the rules of Twitter and other sites.On Wednesday, Twitter placed some of Jones' accounts on a one-week time-out.Many observers have been skeptical about whether a temporary suspension will actually be effective against Jones.When asked about that in Friday's interview, Dorsey said "I don't know" if Jones will change his offensive behavior."We have evidence that shows that temporary suspensions, temporary lockouts will change behavior. It will change peoples' approach. I'm not na?ve enough to believe that it's going to change it for everyone, but it's worth a shot," he said.More importantly, he added, Twitter has to be "consistent with our enforcement.""We can't just keep changing" the rules "randomly, based on our viewpoints, because that just adds to the fear of companies like ours -- making these judgments, according to our own personal views of who we like and who we don't like -- and taking that out upon those people. Those viewpoints change over time," he said. "And that just feels random and it doesn't feel fair and it doesn't earn anyone's trust because you can't actually see what's behind it." 4353

UPDATE 2 p.m., Apr. 18: Lifeguards removed the shark advisory signs at Silver Strand.SAN DIEGO (KGTV) -- Lifeguards warned beachgoers in Silver Strand after several agencies spotted a shark they say could be a great white off the coast Wednesday. According to authorities, the shark was initially spotted by Border Patrol agents in a helicopter above Imperial Beach around 10:30 a.m. The shark was also spotted by a lifeguard in a boat approximately two miles off the coast of Imperial Beach. RELATED: New shark detecting technology being testedThe shark is believed to be between seven and eight foot long. Lifeguards in Imperial Beach say they believe the shark could be a great white. The shark was again seen about half a mile off the coast of Silver Strand, prompting lifeguards to warn beachgoers. Lifeguards chose not to issue a formal public warning because the shark was of moderate size, wasn't behaving aggressively and was in an area with few people nearby, City News Service reports. RELATED: Great white shark attacked 13-year-old boy off Beacon's Beach in EncinitasThe sighting comes less than a year after a 13-year-old boy was attacked by a shark while lobster diving off the coast of Encinitas in September of 2018. Researchers later confirmed that the shark that attacked Keane Hayes was a great white. 1330

VALLEY CENTER, Calif. (KGTV) - As the dual-threat of wildfires and climate change grows, one company says an old method of home building could be the answer to both problems.Rebecca Tasker is the CEO of Simple Construct. Her company builds homes out of straw bales.And, yes, she's heard all of the jokes."I've heard every single 'Three Little Pigs' joke you can think of," Tasker says. "Some good ones, some not so good ones."But the idea of straw bale homes is serious to Tasker."These homes, once they're plastered, are more fire-resistant than conventional homes," she says.The secret is in the construction. Tasker uses high-grade straw bales that are packed solid. She says that makes them like phone books, so they smolder instead of igniting in flames. Also, the plaster her company uses to cover the walls is made from dirt, clay, and more straw. The mixture gives the homes a 1-2 hour fire-resistance rating. Most homes only get a 30-minute rating."The oxygen can't get in to burn," Tasker says.In addition to the fire resistance, Tasker says the homes are environmentally friendly. The thick bales provide a two-foot layer of natural insulation. That blocks sound to 50 decibels. It also keeps the warmth in during the winter and the heat out during the summer."We're actually sequestering carbon in the walls," she says of the process. "We're helping to reverse climate change with these buildings. And as people start to put those two things together, we're getting a lot of business."Tasker says straw homes have been around for more than 100 years and came to California in 1996. Now, she estimates more than 60 are in use in San Diego County.She says the size of the bales can be a drawback, as it takes up valuable square footage on smaller lots. She also doesn't recommend building any higher than two stories.As for bugs or rodents, Tasker says they can't get into the walls because of how densely packed the bales are.Even the interior walls, which are typically made from traditional wood and studs, are packed with the straw/clay mixture.The construction price is comparable to conventional homes with similar insulation and efficiency ratings. Tasker thinks the idea will catch on as more people become more aware of the way these homes can help the planet.As for the little pigs jokes, she wrote a book called "The Story of the Fourth Little Pig." She uses it when she makes presentations to schools and children's' groups to help explain the concept. 2482

Vaccinating children has become a hot topic in the last decade, as arguments often play out on social media, leaving some parents unsure and doctors scrambling to get them the right information. Not too long ago, all mother Megan Whelan was thinking about was how to vaccinate her children."With all the information that's out there all the celebrities who are you know spreading their stories And of course all the blog posts and things you see on Facebook and all of that," Whelan said. "It can be really overwhelming."She decided to take her doctor's advice, but said it would have been nice to have other options for trusted information."I think to be able to go to one place where you can hear both sides of the story would be really interesting," Whelan said. "And you know, where you could hear from of course doctors other professionals but even just a panel of moms."Researchers wanted to know if providing parents with accurate clinical information about vaccines through a website with access to vaccine experts would impact their attitudes about them. They found out it did.Dr. Matthew Daley, a senior researcher at Kaiser Permanente, paneled a group of soon-to-be parents. His team gave some parents vaccine information from a website, others information from a website, social media, blogs, podcasts and chats, and others standard care. Daley's team found that website and social interaction improved attitudes toward vaccines in parents who were hesitant about them."Specifically their confidence in the benefits of vaccines improved," Dr. Daley said. "And then there are concerns about the risks of vaccines decreased."Dr. Daley hopes this can be a model used nationwide to address parents vaccine concerns."Parents need more information than they're able to get in a brief visit with their child's physician," Dr. Daley said. 1880
