A stroll through the archives of Editor & Publisher shows an industry with moments of glory and shame — and evidence that not all of today’s problems are new.
The users had the app installed on their mobile devices for long periods of time (one user had it installed for several years). Then all of sudden, after an update in December, Barcode Scanner had gone from an innocent scanner to full-on malware! Although Google has already pulled this app, we predict from a cached Google Play webpage that the update occurred on December 4th, 2020. #secutiry
Tesla buys $1.5B in bitcoin, may accept the cryptocurrency as payment in the future #blockchain #economy
Tesla writes that earlier this year it “updated [its] investment policy to provide [it] with more flexibility to further diversify and maximize returns on [its] cash that is not required to maintain adequate operating liquidity,” adding that it has the option of putting cash into “certain alternative reserve assets” that include “digital assets, gold bullion, gold exchange-traded funds and other assets as specified in the future.”
Under that banner, the firm has “invested an aggregate $1.50 billion in bitcoin,” going on to say that the well-known electric car company “may acquire and hold digital assets from time to time or long-term.”
South Africa suspends rollout of Oxford-AstraZeneca coronavirus vaccine #health
South Africa on Sunday said it would suspend its rollout of the Oxford-AstraZeneca vaccine after initial trials showed "disappointing" results against the B.1.351 variant of COVID-19 .
The country has received 1 million doses of the jab. It had planned to start using it to vaccinate front-line healthcare workers from mid-February.
The study, involving around 2,000 people, found that the vaccine offered "minimal protection" against mild and moderate cases of COVID-19. It has not yet been peer-reviewed.
Don’t Underestimate the Power of a Walk #health
Walking is one of the simplest and most strategic things you can do for yourself. It takes little preparation, minimal effort, no special equipment, and it can contract or expand to fit the exact amount of time you have available. According to the Centers for Disease Control and Prevention, a single bout of moderate-to-vigorous activity (including walking) can improve our sleep, thinking, and learning, while reducing symptoms of anxiety. When we go for a walk, we perform better on tests of memory and attention; our brain cells build new connections, staving off the usual withering of brain tissue that comes with age; we can actively change the pace of our thoughts by deliberately walking more briskly or by slowing down; and our attention is left to meander and observe, helping us generate new ideas and to have strokes of insight.
