All BART stations back online after computer issue canceled Sunday morning service

SAN JOSE — All BART stations were back online by Sunday afternoon after a computer issue shut the transit agency down all morning.

BART spokesman Jim Allison said the agency restored service to all San Francisco, Peninsula and East Bay stations. Staff were still gathering information about the computer communication problem. In a thread posted on Twitter just before 2 p.m. Sunday, BART officials said one of the dozens of field network devices failed “disrupting the operational communications network.” The system, BART said, “went into fail safe mode and shut down.”

“Engineers and technicians worked to locate the failed device and to restore communications functionality,” BART officials said. “It’s unacceptable not to have service. Engineers have implemented a configuration change to the network which i expected to protect against future device failures that could potentially shut down the system. We apologize for not being able to provide service earlier.

Strong Insider Buying Could Indicate a Bottom in These 3 Stocks

The stock markets are all about timing. Whether your investment strategy is bullish or bearish, what matters is making the right moves at the right time. This is the truth at the heart of the old Wall Street cliché that bulls and bears make money, while pigs get slaughtered. If you get greedy, and start chasing money, you’ll overlook the signs that tell you when to buy or sell. Smart investors will be looking for reliable signs that will indicate a stock’s likely movement. In volatile times like these, those signs are more necessary than ever. One signal that has been correlated with a stock’s future performance is insider activity. This makes sense. Insiders, the corporate officers charged with running a company and producing profitable results for shareholders, are privy to far more information than the average stock

3 “Strong Buy” Healthcare Stocks With Major Catalysts Approaching

It can happen in a New York minute. We are talking about the massive gains certain healthcare stocks are able to notch in what feels like a split second. Unlike names from other areas of the market, earnings results don’t paint the full picture. Rather, other factors like clinical trial data or regulatory decisions can be more useful in determining if a particular company is on the path to life-sustaining revenues. Therefore, any positive update can be the catalyst that sends shares blasting off towards outer space.These plays, however, aren’t without their risk. A disappointing outcome could also be the spark that ignites the flame, only launching shares in the opposite direction. This is what makes compelling healthcare stocks so difficult to spot, but the analysts can help.Using TipRanks’ database, we found three healthcare stocks getting love from the Street

With computer as his instrument, man finds ‘pathway into playing music’

KANSAS CITY, Mo. — While many of us are tied to our computers typing, reading or (these days) meeting, Kansas City musician Tim Harte is creating. He’s the first and only student admitted to the University of Missouri Kansas City’s prestigious Conservatory of Music and Dance with his computer as his instrument.

Kansas City musician Tim Harte is the first and only student admitted to the University of Missouri Kansas City’s prestigious Conservatory of Music and Dance with his computer as his instrument.

Through his unique talent and ambition, he’s built a following in Kansas City. Harte, 40, has found community among fans and fellow artists.

Most of his work has been performed in small venues — record shops and art galleries, many located in the Crossroads Arts District.

That, of course, changed when the coronavirus pandemic hit in March.

His classes, and

Computer hack complicates e-learning at Valparaiso schools | Education

Berta said the district currently is seeking outside technological assistance to halt the attacks and prevent further complications.

He said numerous parents with information technology experience, whose children attend Valparaiso schools, also have volunteered to help.

“The primary job right now is trying to put up a defense system so this outside hacking cannot occur,” Berta said.

He said the school district also has been in touch with the Valparaiso Police Department, and will be getting touch with the Federal Bureau of Investigation, to help catch the hackers and seek criminal charges against them.

More importantly, however, is getting the system back up and running so parents can be assured remote students are once again learning alongside their in-classroom peers, Berta said.

“We’ve had parents asking, ‘What’s going on? Why is it that my child is sitting at the computer and all of a sudden there’s nothing there,'” Berta said.

Choosing to boot or reboot an aging computer

Q: I have a Windows 10 computer that has become increasingly unreliable as it has aged over its three-year life. I’ll be using Outlook, Excel or Chrome and the computer stops responding until I reboot. Often, multiple reboots are necessary before it settles down. I tried deleting all non-Microsoft or Google apps, but to no avail. Do I need to buy a new computer, or is there an alternative?

A: There’s a common misconception about computers in that computer owners think that their PC is slowing down or misbehaving because the hardware is wearing out.

It’s not surprising, as we all know that this is true for things like our car or for household appliances that have a dominant mechanical component with many moving parts that can and do wear out and need replacing.

A team of researchers with Google’s AI Quantum team (working with unspecified collaborators) has conducted the largest chemical simulation on a quantum computer to date. In their paper published in the journal Science, the group describes their work and why they believe it was a step forward in quantum computing. Xiao Yuan of Stanford University has written a Perspective piece outlining the potential benefits of quantum computer use to conduct chemical simulations and the work by the team at AI Quantum, published in the same journal issue.


Developing an ability to predict chemical processes by simulating them on computers would be of great benefit to chemists—currently, they do most of it through trial and error. Prediction would open up the door to the

Best computer speakers 2020: the clearest picks for your PC and setup

A set of the best computer speakers is a great move for any PC and gaming setup. In a world seemingly dominated by headsets, the best PC speakers still open up options for players of games, but also those who use their setups for everything else too. 

A set of the best computer speakers is not a thing of the past anymore; while it did seem like the best gaming headsets and pc headsets for gaming were the only way forward a few years ago, there’s definitely a case to be made for having both now (budget dependent, of course).

For example, I much prefer having a headset on for socially-distanced web chats at work, while I prefer to blast my music on my PC speakers. As for gaming, it depends on what I’m playing: for shooters, I prefer a headset to hear every footstep, but for strategy games like

The Final Frontier: New Course Addresses Lack of Inclusion in Computer Science

Nicki Washington is a woman on a mission: As a professor of the practice of computer science at Duke, she teaches a course called Race, Gender, Class & Computing, which explores the diversity challenges in computer science and the effects that this lack of inclusion has on technology.

“I have long argued that computer science needs a stronger dose of social sciences as part of its curriculum and this class is a chance to do that,” she said.

This is uphill work. Though women make up over 50 percent of the U.S. population, as well as the majority of Americans now earning college degrees, less than a quarter of computer science professionals are female. African Americans and Latinos also hold computer science jobs at a rate well below their percentage in the U.S. population.

And even when these groups do make in-roads into computer science, new recruits tend to be

The UK is building its first commercial quantum computer

The UK’s splashing the cash for its next quantum purchase: the science minister Amanda Solloway has announced the country’s very first commercial quantum computer, backed by a £10 million ($13.36 million) investment from government and industry, to be available to use by businesses within the next few years.

The new machine is expected to help businesses unleash the billion-dollar opportunities promised by the quantum revolution in industries ranging from pharmaceuticals and transport to aerospace.

While the new quantum computer will be physically located in Abingdon, Oxfordshire, partners and customers will be able to access and operate the system over the cloud, to run applications in machine learning, materials simulation and finance. 

Solloway said: “Our ambition is to be the world’s first quantum-ready economy, which could provide UK businesses and industries with billions of pounds worth of opportunities. Therefore, I am delighted that companies across the country will have access to
