NASA has a theory that the solar wind is slowly ripping the atmosphere off Mars through "plasmoids": http//science.nasa.gov/headlines/y2008/21nov_plasmoids.htm

Once the sniper knows there is a reaction to their action, they could try to make the wearer jump off roofs, under moving tanks, etc.

At the very least, it would be difficult to return fire when you have a spasmodic fit whenever the bad guy shoots a couple rounds at you.

Could lead to friendly fire incidents.

"Sorry Joe, the sniper made me do it!"

Could be somebody up there pulled the handle and we're just starting the spin down the bowl?

The next version from Volvo should have rear facing radar too, with the ability to calculate the mass of objects for and aft, the crush zone capabilities of all objects involved, then generate a braking pattern to minimize the impact forces.

It will take until 2020 to be developed and be called the "HindSight Option".

Whenever I visit a PC store, I ask when they are going to get Linux PCs, pointing out the advantages, and suggesting Ubuntu as the easiest to use.

Pretty often, the computer sales clerks and managers have had experience with Linux and we have a good chat, and they wish the store did sell Linux PCs.

More often, its an enlightenment to them and I get a thanks for informing them about it.

Some thing to point out:

* Software is easy got get and pretty much configures itself by just choosing what to install. Comes pre-installed with software for what most people want to do.
* Easy to learn - things like sensible menus let you find things pretty quickly.
* Stability - software just works, and upgrades don't break things, (as much.)
* Keeps getting better steadily.
* Better performance Linux on the same box compared to Windows.
* No DRM to slow the machine down, cause instabilities, and keep you from fair use of the media you own.
* Easy to move back and forth to Windows. What you create with the main user applications like Open Office, and how applications work are the same in Windows and Linux.
* Access to a large community of users and even the software developers that created the operating system and applications to help with problems, and even get a fix if you have a bug.
* Gets you off the "upgrade escalator" with all the disruptions like needing a new machine or radical upgrades to your current machine to be able to work with a new version of your operating system, and having to upgrade software to work with the new operating system version.

If there is demand for Linux PCs in stores, they will be stocked.

Knowledgeable people just need to keep asking for Linux PCs to build the demand.
