Microsoft Windows 10 was a big improvement over Windows 8.1 in most important ways, but it made a big change to the way OneDrive syncing worked. In Windows 8.1, you could see all the files you had stored in OneDrive, but the operating system would only actually download and open the file when you needed to open it. At least for PCs that usually have Internet connections, this was a neat way to offer cloud file syncing without consuming gigabytes of space for infrequently used files on every computer you were signed into. But the behavior could be error-prone—apps could attempt to open the placeholder files created by OneDrive rather than the files themselves—and it could create confusion about which files were actually available offline. So in the initial releases of Windows 10, Microsoft changed the behavior to be more Dropbox-esque . All OneDrive files are now downloaded to your PC when you sign in, though as with Dropbox you can choose to only sync selected folders based on what you need to have available at all times.

Windows 10 fall update will restore (and improve) OneDrive’s best feature
An anonymous reader writes: A recently released draft of the National Institute of Standards and Technology’s digital identity guidelines has met with approval by vendors. The draft guidelines revise password security recommendations and altering many of the standards and best practices security professionals use when forming policies for their companies. The new framework recommends, among other things: “Remove periodic password change requirements.” There have been multiple studies that have shown requiring frequent password changes to actually be counterproductive to good password security, said Mike Wilson, founder of PasswordPing. NIST said this guideline was suggested because passwords should be changed when a user wants to change it or if there is indication of breach. Read more of this story at Slashdot. 
Conventional wisdom: If you eat a lot of salt, you will get thirsty to dilute the sodium level in your blood. The excess salt will be excreted in your urine. But a new study of Russian cosmonauts is challenging this long-held belief. When the cosmonauts ate more salt, the became less thirsty. And their appetite increased – they had to eat 25 percent more to maintain their weight. From the New York Times : The crew members were increasing production of glucocorticoid hormones, which influence both metabolism and immune function. To get further insight, [Dr. Jens Titze, now a kidney specialist at Vanderbilt University Medical Center and the Interdisciplinary Center for Clinical Research in Erlangen, Germany] began a study of mice in the laboratory. Sure enough, the more salt he added to the animals’ diet, the less water they drank. And he saw why. The animals were getting water — but not by drinking it. The increased levels of glucocorticoid hormones broke down fat and muscle in their own bodies. This freed up water for the body to use. But that process requires energy, Dr. Titze also found, which is why the mice ate 25 percent more food on a high-salt diet. The hormones also may be a cause of the strange long-term fluctuations in urine volume. Scientists knew that a starving body will burn its own fat and muscle for sustenance. But the realization that something similar happens on a salty diet has come as a revelation. https://youtu.be/aJEzl31zL-I
