NASA Aeronautics Budget Proposes Return Of X-Planes (phys.org)
If President Obama's recently released federal budget request is approved for the fiscal year beginning Oct. 1, 2016, next year will be the first in a bold 10-year plan by NASA Aeronautics to achieve huge goals in reducing fuel use, emissions, and noise by the way aircraft are designed, and the way they operate in the air and on the ground.
One exciting piece of this 10-year plan is New Aviation Horizons -- an ambitious undertaking by NASA to design, build and fly a variety of flight demonstration vehicles, or "X-planes." The demos included advancements in lightweight composite materials that are needed to create revolutionary aircraft structures, an advanced fan design to improve propulsion and reduce noise in jet engines, designs to reduce noise from wing flaps and landing gear, shape-changing wing flaps, and even coating to prevent bug residue buildup on wings.

Beware of hacked ISOs if you downloaded Linux Mint on February 20th, 2016!

"I'm sorry I have to come with bad news.[1]
We were exposed to an intrusion today. It was brief and it shouldn't impact many people, but if it impacts you, it's very important you read the information below.
What happened?
Hackers made a modified Linux Mint ISO, with a backdoor in it, and managed to hack our website to point to it.
Does this affect you?
As far as we know, the only compromised edition was Linux Mint 17.3 Cinnamon edition.
If you downloaded another release or another edition, this does not affect you. If you downloaded via torrents or via a direct HTTP link, this doesn't affect you either.
Finally, the situation happened today, so it should only impact people who downloaded this edition on February 20th.
How to check if your ISO is compromised?"
