I am from Europe and I think that Asian countries have a huge advantage. You are forced to adopt IPv6, so while the rest of the world still hesitates and waits, you gain lots of experience and get plenty of people trained in a new technology that will eventually become essential. Once the rest of the world wakes up to the reality, you are ready. This actually worries me for my own country...

I used to make fun of women with too many shoes -- until I counted mine. Why aren't there more guys with more than eight (8) pairs of shoes?

- normal, every-day shoes
- shoes for formal occasions
- ski boots (down-hill skiing)
- ski boots (nordic skiing)
- hiking boots
- shoes for the motorbike (need to cover the ankle)
- shoes for the bicicle (clip-in)
- out-door running shoes
- gym shoes (need to be separate and leave no marks)
- boating shoes (no markings, good grip, may get wet)
- sandals (summer, beach, etc.)
- slippers
- snow shoes (not sure they technically count, as you still need an additional pair of shoes)

Besides the shoes for formal occasions (suit, etc.), I don't have any shoes for fashion reasons. I don't use all these shoes on a regular basis, but they all get used occasionally. How did I ever end up with so many shoes?

The problem is that military GPS receiver are most likely hardened against jamming attacks (their receivers have a wider dynamic range). Thus, in order to jam military receivers in a range of 500 yards you will jam civilian receivers in a much wider range (most likely within miles of the jamming device).

Please don't get me wrong, I am not trying to promote this exercise, and I am aware of some of the problems it causes. All I am saying is that they really should perform a jamming attack if they are serious about this threat. To do so, they will need to find a solution that is acceptable to the public in question (i.e., the local fishermen).

The problem is that if you try to manually shut down GPS receivers, you might well forget a few. There was an exercise where they tested how a ship would react to GPS jamming. The expected, of course, the main navigation unit to fail, as it was based on GPS, and then the inertial navigation unit to take over. However, the inertial navigation unit also failed, as it used a time reference based on GPS. Similarly, a whole lot of other systems (if I remember correctly, radar) also failed for similar reasons. In my opinion, if they are serious about this exercise, they will need to jam GPS.

How about switching to the new technology? Some sites have already native IPv6 support, and for others you can use public IPv6->IPv4 proxies. See for instance: http://www.sixxs.net/tools/gateway/

Wind can stop almost immediately. Most wind turbines will continue to produce energy for approximately one minute. This is not enough for conventional power plants to power up, hence currently a high base load is needed. If you can, lets say, power up a conventional power plant within one hour (and maybe wind resumes by then as well), then if you charge your car over night the car will still be charged in the morning. The system will simply optimize the exact times when the car is being charged.

Additional option: Most people don't need 100% of the charge for most days. A user can choose what kind of guarantee is needed. For a normal trip to work (e.g., 50km) 50% would be enough. So the user goes for a cheaper charge for e.g., 70%. The system guarantees only 70%, but if energy is available, the battery will actually be charged more. If the user needs a higher charge (e.g., for a business trip or vacation), the user can choose a guaranteed higher charge but will have to pay more (as the system has less flexibility).

Wind energy and EVs each pose important problems when seen individually. Together they extend each other nicely to solve the individual problems.

There are lots of comments about increasing the load of the electric grid due to more electrical vehicles, etc. and that green energy sources, such as wind, cause problems with the base load. Well, this development can actually help! For instance, the Edison project (http://www.edison-net.dk/) aims at installing an intelligent charging network. Wind or solar power fails due to changing weather conditions, and the charging of batteries for EVs is simply interrupted for a while.

Because his truth is inconvenient?

I have a can opener that works, it's a Swiss army knife (yes, I'm Swiss). I guess one has to learn to use it first, but then it is at least as fast and can also open the cans that have previously been bent by a bad can-opener.

No TV either. As GP said, the program is crap and a waist of time. Slashdot is more entertaining :-)

I have never seen Lost (serious), so I am completely lost in this conversation...

How much of a privacy concern is a global map of Wifi-router MAC addresses? The article (yes, I RTF) makes it sound as if knowing your router's Wifi MAC address could help to connect your online activities to your address (or even just router). But if the network is not open they would not know your public IP address and hence could not really associate the router with users of the network. Especially, if the router is different from the modem (which has it's own MAC address). There could, of course be a Trojan or something on the computer you're using that lets others know which router your computer uses, but this is a more sophisticated thread scenario.

So, how is a global (even if it was public) database of MAC addresses of routers a privacy concern?
