Travel To Mars Fraught With Long-Term Dangers

Living here on Earth, as we all do (I assume if you are reading this you are doing so from somewhere on the planet) it seldom occurs to most of us that our home is flying through space at a pretty good clip. 

We also tend not to think of the cold void of space surrounding us; a void filled with cosmic rays and other nasty stuff that is fortuitously filtered out by our tenuous atmosphere.

However, if we actually get around to sending people to Mars, they will be subject to the effects of the damaging space environment for many months - and the adverse effects of extended exposure are not looking good.
"Exposure to these particles can lead to a range of potential central nervous system complications that can occur during and persist long after actual space travel," said UCI professor of radiation oncology Charles Limoli in a release, "such as various performance decrements, memory deficits, anxiety, depression and impaired decision-making. Many of these adverse consequences to cognition may continue and progress throughout life."

VPN Use Is Up, Up, Up

Since the repeal of the Broadband Consumer Privacy Rules, VPN use and traffic is rather predictably spiking, according to many VPN providers. VPNs are not the b-all and end-all of privacy though, and indeed the usual cretins have stepped in to provide shady VPN services that may actually sell on user data.

Also remember:
ISPs still track your location data and DNS records, even if you're using a VPN. Similarly, a VPN doesn't stop a company from using on-device snoopware to track you (remember Carrier IQ?). Neither will it stop ISPs from charging you a premium for privacy (something both AT&T and Comcast have already experimented with). Nor will a VPN stop a company from using your credit score to provide worse customer service (something CableONE has crowed about). DSL Reports

Microsoft's Mild Mea Culpa Over Windows 10 Obscure Upgrade "Choice"

In a cleansing act before the turn of the year, a Microsoft bigwig has admitted that they may have gotten a little carried away in their zeal to upgrade as many users as possible to Windows 10.
Specifically, Chief Marketing Officer Chris Capossela referred to the upgrade notification that appeared to be deliberately deceptive in the way it handled a users response. If a user clicked the red "X" at the top right of the notice, that closed the dialog box but went ahead and installed the upgrade anyway.
To actually not accept the upgrade, you had to click a link in the notification window itself. Not a few users would come back later and find their system upgraded to Windows 10, or in the process of doing so, when they thought they had expressed their wish not to do so. "Within a couple of hours of that hitting the world, with the listening systems we have, we knew that we had gone too far and then, of course, it takes some time to roll out the update that changes that …

pCloud Cloud Storage On Linux

As a cheapskate user of the Dropbox free plan, I was looking to see if there was another provider that offered a little more free storage than the 2GB from Dropbox (I actually have 2.5GB, due to a couple of bonus offers).
After a bit of research, I came up with Swiss-based pCloud: it has a client for Linux, as well as Windows, Mac, iOS and Android. The free tier offers 10GB of Cloud storage with no file size limits, which is fantastic for my (pretty basic) needs. You can set up your account first from the pCloud website, or during the client install process.
