So, IPv6 does not support private ASs and (more importantly) addresses owned by private companies?

Currently, the company I work for has its own AS and its own IPv4 subnet. We can use whatever ISP we want and still keep our IPs (we use two ISPs for redundancy and are able to change the ISPs to new ones if we need to). Would this be not possible with IPv6?

Using a gun is cheaper, but leaves evidence and if somebody sees you using the gun, they might tell the police.

On the other hand, if the radio equipment can be placed inside a backpack (or two), then there is no evidence that I caused the accident. I am just standing there minding my own business and then walk (or drive) away. If the place usually is full of people, nobody would notice or remember me and would not be able to link me to the accident.

Also, the researchers most likely used general purpose equipment which is more expensive, now that they know how to jam the radar, I am sure that much cheaper devices could be built to do just that.

You can cut the brake lines or plant a bomb in any car, that will do the job quite well. You can also use a bigger car to ram the car off the road, it should also work.

However, messing with the car using radio waves (be it confusing the radar, hacking via bluetooth or wifi or hacking the car via the internet) does not leave evidence. Or, at least does not leave any evidence that may be used to identify you.

So, standing on a bridge and dropping bowling balls or bricks on cars, that are driving under the bridge for fun may get you in trouble. Sitting by the road (or traveling in another car) with an antenna (especially if the equipment and antenna can either be made small/inconspicuous or work from longer ranges) probably won't get you in trouble, since the radio waves do not have your fingerprints.

Dental Floss May Have No Medical Benefits, Says AP Report (gizmodo.com) 257

Joe_NoOne quotes a report from Gizmodo: Flossing may not yield the protective benefits we've been told to expect. Since 1979, the federal government in the U.S. has recommended daily flossing, but by law these dietary guidelines, which are updated every five years, have to be supported by scientific evidence. Surprisingly -- and without any notice -- the federal government dropped flossing from its dietary guidelines this year, telling the Associated Press that "the government acknowledged the effectiveness of flossing had never been researched, as required." AP national writer Jeff Donn reports: "The two leading professional groups -- the American Dental Association and the American Academy of Periodontology, for specialists in gum disease and implants -- cited other studies as proof of their claims that flossing prevents buildup of gunk known as plaque, early gum inflammation called gingivitis, and tooth decay. However, most of these studies used outdated methods or tested few people. Some lasted only two weeks, far too brief for a cavity or dental disease to develop. One tested 25 people after only a single use of floss. Such research, like the reviewed studies, focused on warning signs like bleeding and inflammation, barely dealing with gum disease or cavities. Wayne Aldredge, president of the periodontistsâ(TM) group, acknowledged the weak scientific evidence and the brief duration of many studies...Still, he urges his patients to floss to help avoid gum disease. 'Itâ(TM)s like building a house and not painting two sides of it,' he said. 'Ultimately those two sides are going to rot away quicker.'"

The only way to build a solar power plant in Sahara and use the electricity to power Europe would be to take the required land from whatever country it currently belongs to and also occupy a land strip at least 100km in both directions from the power lines and then mine the hell out of it.

I am sure that there are multiple groups of people in those areas that would really love to blow up that power line, therefore it would need a lot of protection. The 100km buffer around the power plant and the power lines would to protect it from short range missiles.

If the people live there illegally, well, they cannot really object, can they?

As for wildlife preserve - so, it is disused right now. You most likely can't even hunt the wildlife (I would imagine the meat is more radioactive than usual).

Therefore, instead of allocating land that has other uses (say, people live there legally or the land is being used to grow food) or clearing out a non-radioactive forest to build the power plant (and Ukraine really needs it, since the fuel for its other power plants comes from Russia and some big Ukrainian coal mines are currently in the hands of the Russians (sorry - "pro-Russian separatists") why not use this otherwise useless land for the power plant.
