As students and staff return Monday to Virginia Beach schools, the superintendent encourages them to wear blue to honor shooting victims."For us, blue represents the beach, and the color our first responders wear when they rush toward danger to save lives every day," Natalie Allen, communications officer for Virginia Beach, Virginia schools, told CNN.Blue is also the background of the city flag.On Friday, a gunman killed 12 people at a Virginia Beach municipal building.Aaron Spence, Virginia Beach superintendent, Saturday tweeted the announcement about wearing blue, and it was picked up by neighboring school districts.Newport News Public Schools, Suffolk Public Schools, Hampton City Schools, Chesapeake Public Schools, Portsmouth Public Schools, the York County School Division and Isle of Wight County Schools all stated on social media they will join Virginia Beach schools in wearing blue, according to 927

Apple has another fix for its troubled laptop keyboards.Following ongoing complaints over broken and sticky keys, the company said Tuesday it is changing the material used in its butterfly keyboards — which are found on most MacBook Air and MacBook Pro computers — and expanding its repair program.Less than a year after the debut of its latest MacBook Pro model, the company announced a faster 8-core MacBook Pro with one very notable change: a slightly revamped version of its third-generation butterfly keyboard.Apple didn't disclose details over the change in material, but said it believes the update will significantly cut down on user complaints.The MacBook Pro line starts at ,799 for the 13-inch model and and ,399 for the 15-inch version.Unlike most laptop keyboards that use a "scissor mechanism," Apple's butterfly method expands like wings, opening itself up to dust and other debris. The concept allowed Apple to create a slimmer keyboard design, but it's been called by some 1006

BIRMINGHAM, Ala. (AP) — The base of a Confederate monument in Alabama is all that remains Tuesday morning in Birmingham's Linn Park. Live video recorded overnight shows crews worked into the early morning hours dismantling the top portion of the obelisk in pieces. It comes about a day after protesters tried to remove the monument themselves during a protest over police brutality, including the death of George Floyd. The stone pieces were hauled off on a flatbed truck. It's unclear where they were taken. Crews were expected to return later Tuesday to finish removing the monument. 597

  

Apple is teasing the future of its software, and it is dark.At its annual World Wide Developers Conference in San Jose, California, Monday, Apple is announcing new features and designs for the operating systems that run on iPhones, iPads, Macs, Apple Watches and Apple TVs.iTunes is being replaced after 18 yearsAs expected, Apple is killing its once groundbreaking, often bemoaned audio and video app, iTunes.After 18 years, the app will be phased out and replaced with three separate apps that are familiar to iOS users: Apple Music, Apple TV and Apple Podcasts.Apple's Craig Federighi had a sense of humor about user dissatisfaction with iTunes, joking, "Customers love iTunes and everything it can do."iOS 13: iPhones are going dark, Maps are going street level"And now, lets begin our descent into darkness," said Federighi, introducing the new updates to iOS.IPhones, iPads and the iPod touch will now have an optional dark mode coming in iOS 13. Dark modes favor lighter text on dark backgrounds, and are said to be easier on the eyes when looking at a screen in a dimly-lit environment. Many apps already have their own individual dark modes, and Macs have a system-wide dark mode.The core, built-in iOS apps are also getting a glow-up. Mail is adding more fonts and formatting options, Notes has a new look, and the Reminders app has been beefed up with a number of new features, including tagging people and making smarter to-dos.Apple Maps, which has struggled to compete with Google Maps since it launched in 2012, is getting a new, more detailed look at the end of this year in the US. Apple says it rebuilt the app from the ground up by sending hundreds of planes and cars with custom sensors and lidar sensors over 4 million miles across the country. It's also adding other Google Maps-like features, such as favorite locations and interactive street view, which it calls "look around."With iOS 13, you'll be able to share your name and your photo (or custom emoji) in Messages. (This information will only be shared when you message with someone.) It's adding more personalization options for its "memojis," including makeup, piercings, more teeth options like gaps and grills, earrings, additional hair options, hats and glasses. The avatars will work on more devices, Mail, and even some third-party messaging apps like WeChat.The iOS update will also impact Apple's AirPods, which will be able to read your incoming email to you in Siri's voice, and let you share audio from your AirPods. The new feature, called AirPods Audio Sharing, will supposedly let you bring your AirPods close to someone else's and — with permission — tap a button to start listening to what they're rocking out to. Siri will support live radio with third-party services like IHeartRadio.Speaking of music, remember the HomePod? Apple's underwhelming take on the smart speaker was launched two years ago, and now it's adding some new features, including being able to recognize the voices of different users — just like Amazon and Google's smart speakers.Privacy is, again, at the center of Apple's sales pitchApple is launching its own login platform called Sign in with Apple, which will let you log in to outside apps with FaceID. It has the option to hide your real email address and instead give each app a randomly generated email address. Google, Twitter and Facebook have their own sign-on tools already, but some security experts advise against using a single sign-in service across multiple sites, in case your one login is compromised. Sign In With Apple will work across Apple devices, including Macs and iPhones, but only with apps that update to support the feature.Other privacy updates include a new option to limit how much tracking information third-party apps can collect. Now you can choose to allow an app to get location information just once, as well as receive reports on background tracking. Apple is also blocking the ability for outside apps to sneakily gather location information via your Wi-Fi and Bluetooth connections.A more independent Apple Watch can track periods, monitor soundApple is bringing a number of new tools to the Apple Watch as part of watchOS 6, many of which will help the watch run more independently of the iPhone. The Watch will have its own App Store, a calculator with tip tools, an audiobooks app, and Apple's Voice Memos app, for more subtly recording audio (check local laws). It's also adding a pair of new health tools. Cycle Tracker adds tools for tracking periods and fertility -- tools that are also being added to the iOS Health app. A new Noise app uses the built-in microphone to measure environmental sound and warn you when the decibels are too high and could hurt your hearing. Apple says it does this by sampling audio and does not record anything.Mac Pro is back, fast, and grateApple is releasing an update of its Mac Pro desktop for professional Mac users for the first time since 2013. The company is ditching its previous "trash can" cylinder design for a more traditional tower shape that will probably earn the new (better?) nickname "cheese grater." The computer is silver, covered in holes and has a handle on top. But professionals will likely care more about what is inside: a 28-core Intel chip and 1.5 TB of system memory. It will start at ,000 and be available in the fall.The company is also making its own display again, called the Pro Display XDR. Also covered in holes, but on the back, the new display is rotatable and detachable. The 32-inch 6K retina LCD display starts at ,999 and will be available in the fall. The required stand to hold said monitors will cost 9.The-CNN-Wire? & ? 2019 Cable News Network, Inc., a Time Warner Company. All rights reserved. 5765

  

British police identified the man suspected of killing two people in a terrorist attack near London Bridge on Friday as 28-year-old Usman Khan.Khan was convicted in 2012 for terrorism offenses and had been living in the Staffordshire area after he was released from prison last year with an ankle monitor, Metropolitan Police Assistant Commissioner Neil Basu said in a statement.Basu said authorities are not "actively seeking anyone else in relation to the attack."Police officers shot and killed Khan after two people were stabbed to death, and at least three others were injured during the attack on Friday, London Metropolitan Police said. The suspect had a fake bomb strapped to him when he was shot, police said.Speaking before a meeting of the UK government's emergency response committee Cobra on Friday night, British Prime Minister Boris Johnson said it was important to enforce appropriate prison sentences for criminals."I have long argued that it is a mistake to allow serious and violent criminal to come out of prison early, and it is very important that we get out of that habit, and that we enforce the appropriate sentences for dangerous criminals, especially terrorists," he said in a pool interview.British authorities were searching a property believed to be linked with the suspect late Friday, a law enforcement source told CNN.2 people killed, 3 others hurtThe rampage began just before 2 p.m. at Fishmonger's Hall, a historic building on the north side of the London Bridge. The suspect was attending an event in the building organized by the University of Cambridge's Institute of Criminology, according to the assistant commissioner and the organizer's website."We believe that the attack began inside before he left the building and proceeded onto London Bridge, where he was detained and subsequently confronted and shot by armed officers," Basu said.Video filmed by a bystander shows a man being wrestled to the ground by several bystanders on the northern end of the bridge, shortly after police were called to Fishmonger's Hall.Tom Gray, a tour guide who tried to apprehend the suspect, told CNN affiliate ITV that the attacker was "wielding two knives, one was duct taped to his hand." After other bystanders had held the suspect down, Gray said he tried to "stamp the other knife from his wrist" and then kicked it further down the bridge.Lloyd Griffiths, 35, who was on a bus on the bridge, said he saw the attacker had a large blade."I saw a shine on a knife or metal blade, it was startling. It was large blade, it wasn't small, and then I was locked on the bus, people tried to tackle to man trying to fight him, ordinary people jumping out of the car, trying to fight him," Griffiths said."Then police ran over with guns, screaming," before shooting the man, Griffiths added. Multiple emergency vehicles quickly arrived on the scene as crowds of people fled the area.A man and woman were killed in the attack on Friday, Basu said in a statement early on Saturday. Three others, a man and two women, were injured and remained hospitalized. None of the victims have been named.Authorities have not discussed the motive for the attack but earlier on Friday, Basu said it had been declared as a terrorist incident."I must stress, however, that we retain an open mind as to any motive. It would not be appropriate to speculate further at this time," Basu told reporters Friday afternoon.In the wake of the attack, Metropolitan Police Commissioner Cressida Dick said officials decided to enhance patrols, including armed and unarmed officers, in the area and across the city and are encouraging residents to cooperate with police."Fighting terrorism takes effort and determination from all of us. If you have any information or concerns, please do contact us," Dick said. "The empty ideology of terror offers nothing but hatred and today I urge everyone to reject that. Ours is a great city because we embrace each other's differences, we must emerge strong and still from this tragedy."The incident comes more than two years after eight people were killed and dozens more wounded in a terror attack at London Bridge.London mayor Sadiq Khan praised the "breathtaking heroism" of "ordinary Londoners" who risked their lives to intervene in the incident. "We are resolute, we stand united in the face of terrorism and we will not allow anybody to divide us," Khan said in a press conference.President Donald Trump has been briefed on the incident and is monitoring the situation, Deputy White House Press Secretary Judd Deere said in a statement.Scenes of panic at a busy London hubWitnesses described scenes of panic as swarms of Londoners were rushed away from the bridge by police, while major buildings surrounding the area including the Shard skyscraper were put on lockdown.Simon Shorey was eating with his family in a burger restaurant when the incident occurred. "The whole restaurant had people under their tables and sat down on the floor," he told CNN. He says people were trying to keep updated with the latest developments on their phones and the atmosphere started to calm down."There were people running down the street just outside the windows of the restaurant. They weren't screaming at that time, but people were running back down and after a few more minutes we were told 'everyone out, everyone out.'"Olivia Bizot, who was present at the Boston marathon bombing in 2013, added: "I was coming towards the bridge on my bike and I heard explosions. I didn't really assume it was gunshots at first.""All of sudden all these people came running like a flood of people ... A few years ago, I was at the Boston marathon bombings and I was at the finish line just before it occurred and it was the same thing — everyone running, panic on their faces," she added.A white lorry was seen stationary across multiple lanes of traffic in the middle of the bridge, which armed police approached after the incident. It was unclear whether the vehicle is related to the attack.Other videos from the scene showed people evacuating pubs near the bridge. London Bridge is a busy area of the city which houses several restaurants, bars and businesses and is near Borough Market. It was also Black Friday, one of the busiest shopping days of the year.Jinnat Ui Hasan told CNN he was in a meeting in a building near the incident when he heard "more than five" gunshots.Elsewhere, Stevie Beer, 26, told CNN that her place of work which overlooks the bridge was in lockdown Friday afternoon."A colleague out for lunch messaged to say there had been an incident on London Bridge and he was unable to cross back over the river. I went straight to the window and saw hundreds of people running off the bridge down Tooley Street," Beer told CNN."People looked so panicked. It was haunting. There were at least half a dozen police cars and halted buses. Our building is now on lockdown, but we've not been given any concrete information," she added soon after the incident. 7007
