Today in Beijing is also starting the first World Mind Sport Games, a series of team and individual tournaments of chess, go, bridge, draughts and Xiangqi (chinese chess).

The point is to try to understand the cars and how they are put together by analyzing the parts that go flying off in the collision, and the speed and direction that those parts went flying.
Actually, they expect to obtain from the collision.
- Three bicycles
- one motor bike
- An amazing big truck nobody has seen yet !
The truck will move about 10 meters then explode in several vehicules that will be analysed.
As msauve said, when a system need accurate time intervals and don't want to bother with lead second, it can just use TAI.
The "UTC without leap second" proposal is a workaround, an ugly hack some clueless guy want to impose to the whole world because of wrong design in their own systems.
See the DoD poll, they reduce the problem to a cost issue, in the most naive way "how much line of software code: less than 20, 20-40, 40-100, more than 100." This is ridiculous.
In such a matter, you just have to perform the right thing. Even if you consider cost, a wrong decision will alway cost more in the long term.
100% agree. It's a pity to see current lobbying against leap second in UTC. It is plain wrong, yet it has chance to succeed for ununderstandable political reasons.
Ok we don't need solar time accurate to the minutes for everyday life. Having a time system whose purpose is to avoid issue in thousands year is perhaps over long term thinking.
But now everybody has it and is used to it, by bother changing it ? It cost much more than just keeping counting leap second has we do : if we remove leap seconds for UTC, some systems that rely on UTC to be on par with solar time will break.
Switching to TAI would be a real mess, as nobody will switch at the same time. That's why they want to keep UTC with just stoping adding lead second.
This lobbying itself is just a waste of resources. Just stop it now, keep leap seconds, and think about more important matters.
CNIL gives you constraint when as an individual, association or company you create a database with nominative entry. You have to declare your database to the CNIL. You are not allowed to store all type of data (like political and religious affiliations). People can request to be removed from your database or know what you keep about them.
Of course as a home user you are given only one routable IPv4 address and it is wonderfull to be able to connect all your devices using NAT. You may even believe it brings you security by hidding your computers true address.
With IPv6, you will have as many routable address as you need. You will also have real security thanks to IPSec (one thing that is broken with NAT).
Unless there is a huge entrenched reason that forces NAT vendors to specifically target them, nobody will use a protocol that doesn't work with a NAT.
This is exactly why NAT is wrong. This is a severe limitation to internet innovation. Anyone working on a non trivial protocol must spend a large share of his effort to handle NAT. In some cases it is even not possible so a nice idea is simply dropped.
IPv6 large adoption will allows more innovation in network applications. Then we will see how we were limited by IPv4.
You (and many people) are so accustomed to NAT you don't even see how wrong it is.
There is nothing really difficult to use IPv6 address instead of IPv4. Writing (or even using) a network application having to deal with NAT is a real pain.
If I understand Progman3K, it is more precise than that.
Say the universe is 15 billion years old. We can observe a 15 billion light year radius ball around us.
Well, in a sense, this ball is the whole universe. Saying anything farther exists has no meaning, if your "exist" definition is "being part of our universe".
If you see the visible universe as part of a bigger thing, as it seems reasonable. If you imagine a place 30 billion light years away and at the same date as us, as no photon ever came to this place to us it is in a quantum superposed state of anything that is possible. So, that is a different universe.
I have used their services and I know how it works.
You generate your private and public keys, and you keep your private key to you.
Verisign has its own private key (well actually it has more than one), it use it to digitally sign a document telling that your public key is really associated to you. That's what is a certificate.
No, Verisign doesn't have your private key, only your public one (that is public anyway). They don't need it to issue a certificate, they just sign your public key to authenticate it.
If you "own" Verisign server, you can pretend to be me (by issuing a new certificate) but you can't decrypt data encrypted previously with the real private key.
Sure NSA has big computers and talented cryptography experts. They may know some flaws in encryption schemes or in their implementations, and may be able to decrypt your private data.
But having access to verisign root server is no help to decrypt verisign customers private data.
When you sell any kind of hardware with an embeded web server for remote usage and administration. You want to allow SSL encryption, as the administration of the box requires a login you want to protect.
One thing you can't do, is to put your own private key corresponding to a certificate that identify you inside this box. It would be a nightmare to ensure it can't be retrieved, as anyone buying your product has a physical access to it.
So a self-signed certificate is the only solution, but your customers will have an ugly warning.
Yes, government job is to control the behavior of the population when it is relevant. Here, it is relevant to limit the liberty to burn any amount of fuel a 4x4 owner would like, as it cause a pollution.
Government can decide what is right as long as I can vote for another one when I don't agree. Of course democracy doesn't work that well, but other political systems are worse.
In the fuel tax case, I'm afraid it is high mostly because there is money available there to be taken. It was also a strategic decision for countries that depend on other for their oil ressources.
Anyway, I still think high fuel tax in europe has a good overall effect.

This, of course, doesn't apply to the army and police. If you ever dream to have access to the file the french national security organisation(RG: renseignements généraux) has about you, the CNIL won't help you.
I afraid all countries have this kind of database. This is not so bad in this case to publicly admit it.
Yes
You have only formatted a second hand hard drive without looking for previous content. Is it forbidden ?
Is you open your mouth, people can still imagine you keep a copy somewhere and you have made the story public to find potential buyers.
In such a case, I would have just formatted the drive.
Why bother, except to attract troubles ?
Excuse me for my laziness: see drawback section of NAT wikipedia article there.

...where it explains IPv6 will succeed anyway.

Perth ! Greg Egan lives there !
I would consider placing a bet. Problem is my own life is worth much less than $300K
