88 Out of Top 200 US Cities Have Seen Internet Speeds Decline This Past Week

Slashdot - Fri, 2020-03-27 03:30
An anonymous reader quotes a report from TechCrunch: The impacts of telecommuting, shelter-in-place laws and home quarantines resulting from the COVID-19 outbreak are starting to impact broadband speeds across a number of U.S. cities, a new report has found. According to broadband analysis site BroadbandNow, 88 out of the top 200 most populous U.S. cities analyzed have now experienced some form of network degradation over the past week, compared with the 10 weeks prior, as more people are going online to work from home, video chat and stream movies and TV to keep themselves entertained. In a small handful of cities over the past week, there have even been significant degradations with download speeds dropping more than 40%, compared with the 10 weeks prior. It's not necessarily the areas hit hardest by the spread of the novel coronavirus that are experiencing the worst problems. Cities including LA, Chicago, Brooklyn and San Francisco have seen little or no disruption in download speeds, the report claims. Seattle is also holding up well. But New York City, now considered the epicenter of the virus in the U.S., saw download speeds drop by 24% last week, compared to the previous 10-week range. That said, NYC home network connections, which have a median speed of nearly 52 Mbps, are managing. The good news is that in the majority of markets, network speeds are holding up. But of the 88 out of 200 cities that saw declines, more than two dozen saw dips of either 20% below range or more, the data indicates. The three cities seeing network degradations over 40% include: Austin, TX (-44%), Winston Salem, NC (-41%), and Oxnard, CA (-42%). San Jose, CA was nearing this range, with a drop of 38%.

Instead of Hazard Pay, Spectrum Offered a $25 Gift Card To Technicians Who Enter Homes Amid the Coronavirus Pandemic

Slashdot - Fri, 2020-03-27 01:25
Amber Jamieson writes via BuzzFeed News: Spectrum technicians connecting cable and internet for customers during the coronavirus outbreak will receive a $25 gift card for a local restaurant as a "token of our appreciation" from management, after staff called for hazard pay and protective equipment. "These gift cards never expire, so if you choose a restaurant that is currently not open, the card will remain valid for future use," read the Monday night internal staff email from Tom Adams, the executive vice president of field operations. "Please take some time out of your busy day to enjoy a meal and recharge." Field technicians told BuzzFeed News on Monday night they feared going into people's homes during the pandemic to fix their internet and cable without gloves, a mask, or hand sanitizer in case they got sick or carried the virus to other customers or loved ones. On Monday night, the company announced it was offering a $25 weekly gift card as a thank you -- an initiative that left many workers who spoke with BuzzFeed News unsatisfied. "Would you do it for $25?" asked a field technician from Irwindale, California, who asked to remain anonymous, along with the other technicians quoted in this story, to protect his employment. He called Spectrum management "vultures."

Engineers Test a Powered 'Ankle Exoskeleton' To Make Running Easier

Slashdot - Fri, 2020-03-27 00:45
Engineers from Stanford University developed a motorized exoskeleton rig that attaches around the ankle and foot and found that it made running 15 percent easier. "They explained that when the exoskeleton's motor is switched on, it reduces the energy cost of running and allows the user to run longer than they're usually capable of," reports Engadget. "The device can also boost a runner's speed by as much as 10 percent." From the report: Here's how the exoskeleton works: Its motors tug a cable running through the back of the rig from the heel to the calf. That pulls the foot upward during the toe-off, extending the ankle at the end of every step. Team member and Stanford grad student Delaney Miller said: "Powered assistance took off a lot of the energy burden of the calf muscles. It was very springy and very bouncy compared to normal running. Speaking from experience, that feels really good. When the device is providing that assistance, you feel like you could run forever."

Unpatched iOS Bug Blocks VPNs From Encrypting All Traffic

Slashdot - Fri, 2020-03-27 00:02
An anonymous reader quotes a report from Bleeping Computer: A currently unpatched security vulnerability affecting iOS 13.3.1 or later prevents virtual private network (VPNs) from encrypting all traffic and can lead to some Internet connections bypassing VPN encryption to expose users' data or leak their IP addresses. While connections made after connecting to a VPN on your iOS device are not affected by this bug, all previously established connections will remain outside the VPN's secure tunnel as ProtonVPN disclosed. The bug is due to Apple's iOS not terminating all existing Internet connections when the user connects to a VPN and having them automatically reconnect to the destination servers after the VPN tunnel is established. "Most connections are short-lived and will eventually be re-established through the VPN tunnel on their own," ProtonVPN explains. "However, some are long-lasting and can remain open for minutes to hours outside the VPN tunnel." During the time the connections are outside of the VPN secure communication channels, this issue can lead to serious consequences. For instance, user data could be exposed to third parties if the connections are not encrypted themselves, and IP address leaks could potentially reveal the users' location or expose them and destination servers to attacks. Until Apple provides a fix, the company recommends using Always-on VPN to mitigate this problem. "However, since this workaround uses device management, it cannot be used to mitigate the vulnerability for third-party VPN apps such as ProtonVPN," the report adds.

'League' of Cybersecurity Professionals Band Together To Help Hospitals Fight Off Hackers

Slashdot - Thu, 2020-03-26 23:20
pgmrdlm shares a report from NBC News: A growing group of cybersecurity professionals is volunteering their expertise to help hospitals fight off hackers while doctors and nurses fight the coronavirus. Calling themselves the CTI League -- Countering Threat Intelligence, and a nod to the superhero team the Justice League -- the group has swelled from a handful of professionals to 450 members worldwide in less than two weeks. "If some hospital gets attacked by some ransomware and wouldn't be able to pay, people will die because they wouldn't be able to get the medical services needed," said the group's founder, Ohad Zaidenberg. Coordinating over Slack, the CTI League identifies what types of vulnerabilities active hackers are using, then searches for hospitals and other medical facilities that might be vulnerable to them so that they can fix them first. "The first thing we want to do is neutralize attacks before they happen. The second is to help any medical organization after they are attacked," Zaidenberg said.

Elon Musk Says Tesla's New York Factory Will Make Ventilators 'As Soon As Humanly Possible'

140Mandak262Jamuna writes: Elon Musk announced that the Gigafactory in Buffalo, New York, making solar roof tiles and battery packs for home energy storage is switching to making ventilators in collaboration with Medtronic. "Days after offering 1,255 free ventilators to help deal with the coronavirus outbreak, Tesla boss Elon Musk said the company's New York factory will restart to make more," reports CNET. "Giga New York will reopen for ventilator production as soon as humanly possible. We will do anything in our power to help the citizens of New York," he tweeted on Wednesday. New York Gov. Andrew Cuomo said the state needs 30,000 ventilators at the peak and they have 400 at hand.

The US Now Leads the World In Confirmed Coronavirus Cases

Slashdot - Thu, 2020-03-26 22:03
An anonymous reader quotes a report from The New York Times: Scientists warned that the United States someday would become the country hardest hit by the coronavirus pandemic. That moment arrived on Thursday. In the United States, at least 81,321 people are known to have been infected with the coronavirus, including more than 1,000 deaths -- more cases than China, Italy or any other country has seen, according to data gathered by The New York Times. With 330 million residents, the United States is the world's third most populous nation, meaning it provides a vast pool of people who can potentially get Covid-19, the disease caused by the virus. And it is a sprawling, cacophonous democracy, where states set their own policies and President Trump has sent mixed messages about the scale of the danger and how to fight it, ensuring there was no coherent, unified response to a grave public health threat. A series of missteps and lost opportunities dogged the nation's response. Among them: a failure to take the pandemic seriously even as it engulfed China, a deeply flawed effort to provide broad testing for the virus that left the country blind to the extent of the crisis, and a dire shortage of masks and protective gear to protect doctors and nurses on the front lines, as well as ventilators to keep the critically ill alive. "The world will be a different place when the pandemic is over," the report concludes. It suggests India may become the next global hotspot for virus cases as "it, too, is a vast democracy with deep internal divisions. But its population, 1.3 billion, is far larger, and its people are crowded even more tightly into megacities."

AI Versus the Coronavirus

Slashdot - Thu, 2020-03-26 21:26
A new consortium of top scientists will be able to use some of the world's most advanced supercomputers to look for solutions. From a report: Advanced computers have defeated chess masters and learned how to pick through mountains of data to recognize faces and voices. Now, a billionaire developer of software and artificial intelligence is teaming up with top universities and companies to see if A.I. can help curb the current and future pandemics. Thomas M. Siebel, founder and chief executive of C3.ai, an artificial intelligence company in Redwood City, Calif., said the public-private consortium would spend $367 million in its initial five years, aiming its first awards at finding ways to slow the new coronavirus that is sweeping the globe. "I cannot imagine a more important use of A.I.," Mr. Siebel said in an interview. Known as the C3.ai Digital Transformation Institute, the new research consortium includes commitments from Princeton, Carnegie Mellon, the Massachusetts Institute of Technology, the University of California, the University of Illinois and the University of Chicago, as well as C3.ai and Microsoft. It seeks to put top scientists onto gargantuan social problems with the help of A.I. -- its first challenge being the pandemic. The new institute will seek new ways of slowing the pathogen's spread, speeding the development of medical treatments, designing and repurposing drugs, planning clinical trials, predicting the disease's evolution, judging the value of interventions, improving public health strategies and finding better ways in the future to fight infectious outbreaks.

Worldwide Coronavirus Cases Surpass Half a Million

Slashdot - Thu, 2020-03-26 20:22
According to Johns Hopkins University, there are now more than 510,000 confirmed COVID-19 cases worldwide and more than 22,000 people have died from the new coronavirus. While China still has the most confirmed cases, the United States and Italy are close behind. CBS News reports: In the United States, more than 1,000 people have died and more than 75,000 people have been infected. An unprecedented number of Americans applied for unemployment benefits last week as the virus shuttered businesses and normal life across large swaths of the country came to a halt. Roughly 3.3 million people filed a claim for jobless aid in the week ending March 21 -- a nearly fivefold increase over the previous weekly record set in 1982. The Senate has passed an unprecedented $2 trillion relief package to help workers, businesses and the severely strained health care system survive the pandemic. UPDATE: The United States now leads the world with confirmed coronavirus cases. "[A]t least 81,321 people are known to have been infected with the coronavirus, including more than 1,000 deaths -- more cases than China, Italy or any other country has seen," reports The New York Times.

Zoom iOS App Sends Data to Facebook Even if You Don't Have a Facebook Account

Slashdot - Thu, 2020-03-26 20:05
As people work and socialize from home, video conferencing software Zoom has exploded in popularity. What the company and its privacy policy don't make clear is that the iOS version of the Zoom app is sending some analytics data to Facebook, even if Zoom users don't have a Facebook account, according to a Motherboard analysis of the app. From the report: This sort of data transfer is not uncommon, especially for Facebook; plenty of apps use Facebook's software development kits (SDK) as a means to implement features into their apps more easily, which also has the effect of sending information to Facebook. But Zoom users may not be aware it is happening, nor understand that when they use one product, they may be providing data to another service altogether. "That's shocking. There is nothing in the privacy policy that addresses that," Pat Walshe, an activist from Privacy Matters who has analyzed Zoom's privacy policy, said in a Twitter direct message. Upon downloading and opening the app, Zoom connects to Facebook's Graph API, according to Motherboard's analysis of the app's network activity. The Graph API is the main way developers get data in or out of Facebook.

Google To Resume Chrome Updates it Paused Last Week Due To COVID-19
