Months ago, before Windows 11 even shipped, beta users were complaining that Windows 11 was slowing their random write speeds on NVMe SSD by more than half.
Now, three months later and two months after the launch of the OS, it appears the issue is persisting.
Recent CrystalDiskMark benchmarks of the Samsung 980 Pro SSD performed by PleasedPen25317 show a massive reduction in random write speeds for any partition with Windows 11 installed.
Breakthrough Starshot’s ultra-lightweight spacecraft will have to travel four light-years to reach Alpha Centauri. To put it another way, our nearest neighboring star system is a mind-shattering 40,208,000,000,000 (40 trillion) km away from Earth.
As a point of reference, our fastest and most reliable technology today for long-range space travel is the ion thruster, which is powering NASA’s DART mission to a nearby asteroid at speeds of 15,000 mph (24,000 km/h). However, according to NASA, with the ion thruster, it would take 18,000 years, or approximately 2,700 human generations, to get to Alpha Centauri.
Impressively, the Breakthrough Starshot team believes its spacecraft, with the help of lasers located on Earth, will be able to reach unprecedented speeds, allowing it to travel the distance to Alpha Centauri in only 20 years. If it does reach its destination, the probe spacecraft will then send back the first-ever images taken from another solar system, allowing a never-before-seen window to distant planets that may or may not resemble Earth.

Ten men and women are ready to begin training so they can journey to the International Space Station, the moon and beyond. The new astronaut class of 2021 was announced by NASA on Monday.
The 10 astronaut candidates, the first new astronaut class in four years, were selected from more than 12,000 applicants. The agency’s administrator, Bill Nelson, introduced them live from Ellington Field near NASA’s Johnson Space Center in Houston, where the candidates will spend the majority of the next two years training beginning in January 2022.
“Today we welcome 10 new explorers, 10 members of the Artemis generation, NASA’s 2021 astronaut candidate class,” Nelson said. “Alone, each candidate has ‘the right stuff,’ but together they represent the creed of our country: E pluribus unum — out of many, one.”
There are many types of rocket fuel. Some are more useful on a particular planet. And some can be created by bacteria.
In the first study of its kind, researchers from the University of British Columbia (UBC) and Vancouver Coastal Health (VCH) have demonstrated that a stem cell-based treatment delivered through an implantable device can produce insulin in the human body.
Disney+, Coinbase, Slack and other websites were taken down for some users as a result of the AWS outage.
“We are seeing improvement in availability across most AWS services,” the notice stated. “We continue to work toward full recovery for all impacted AWS Services and API operations.”
Among the services that reported issues as a result of the outage were Disney’s streaming subscription service, Disney+, Netflix, Slack, Ticketmaster, stock trading app Robinhood, and Coinbase, the largest cryptocurrency exchange in the U.S.
The outage also brought down critical tools used inside Amazon. Warehouse and delivery workers, along with drivers for Amazon’s Flex service, reported on Reddit that they couldn’t access the Flex app or the AtoZ app, making it impossible to scan packages or access delivery routes.
Summary: A ten-minute run increases activation of the bilateral prefrontal cortex, improving mood and cognitive function.

Running may be a useful activity to undertake for better mental health. University of Tsukuba researchers have found that only ten minutes of moderate-intensity running increases local blood flow to the various loci in the bilateral prefrontal cortex —the part of the brain that plays an important role in controlling mood and executive functions.

Skills shortages are easily brushed off as Covid collateral, but in fact, they are much more troubling signs of an education system that is not preparing people for the future of work. These issues stem from a union of education and employment that has been designed to fill specific criteria for the workforce, but the job market that young people are training for today will require a much greater emphasis on human skills to complement the repetitive tasks handled by AI and automation.
But bringing up young people with the human skills they need for a changing world of work is a mammoth task that must combine the powers of government, businesses, and dedicated organizations to reshape our education systems and integrate them with the communities they serve. I spoke with Justin van Fleet, Executive Director of the Global Business Coalition for Education (GBC-Education), about the need for a holistic and skills-centered approach to education, and how change needs to start as early as possible.
