That 64-bit prefix is actually the ISP's subnet. The confusion is really my fault, as I used poor phrasing when I said they "give" the user a/64... what they do is advertise it. The machine then takes that 64-bit prefix, tacks their 64-bit MAC on the end (or, if that RFC is used, some randomized identifier), and voila, they're connected.
ok, I see what you mean. But it would surprise me if that will be how it is done.
ISPs will need to keep track of who has which IP at which time. At least in the EU they are required by law, afaik in the US they make this information available for law enforcement too (occasionally even without warrant).
This bookkeeping is just so much easier if every user gets a fixed IP (or -subnet), so i do not see why they would allow everone to just pick any address in their subnet.
IP addresses (even IPv6) are addresses, not phone numbers. The address identifies the place where the packets are supposed to go, not the person to whom they're supposed to go. So it can be used as a unique household identifier instead of a unique person identifier. That does not make it less of a privacy concern. Sure you can change this identifier by changing ISPs or using a PC in a different location. It is still a lot harder to change than a cookie or a dynamic IP, and impractical to do so each day. Advertisers will love this.
Not necessarily. Unless the user explicitly asks for a routable/48 or/56, I'll bet most ISPs just give each user a/64 and have them autoconfigure, in which case there's always the Privacy Extensions for Stateless Address Autoconfiguration option.
But no matter what the user configures, he is stuck in the/64, or do I missunderstand this? So if an ISP is known to give its customers a/64 each, then to identify them one just has to discard the later part of the address. Sure it is not a perfect identifier, you cannot differentiate between people in a household if they go the extra mile and configure it right, but it is miles better than anything currently used.
Once we get IPv6 everywhere, most ISPs will simply assign each user a fixed subnet, since that is so much easier and more efficient than keeping track of dynamic assignements. Same for large networks that currently use NAT.
So the vast mayority of users will have a unique non-changeable ID, making cookies or this kind of tracking obsolete.
Theyre on the job! #5 - Action commenced at 09.33GMT. Weight: 152KG.
Where did those extra 2.2 pounds come from?
How accurate can such a sensor be anyway? I think you would need sensors under each of the feet of the bed, and then average over quite some time to get any accuracy. How expensive are presure sensors that could do this?
Has anyone done this before? The fact that the previous three measurements are exactly equal makes me suspect that someone simply fakes the tweets. Even my body scale is less exact than this.
I would love to know what sort of weight sensor he used. Unfortunately the lack of technical details and the fact that he tweets the exact weight, without any indications of preprocessing, makes me suspect a fake.
Anyone know what pressure sensors and processing you could use to get the exact weight?
If something falls at 0 ft/second, it weighs nothing. If it falls up, it weighs less than nothing.
Since science has so far not found anything that weighs nothing while at rest, nor anything that wheights less than nothing, that is pure speculation. It is unknown how such objects would behave
Civil contempt means that the person who is locked up holds the keys to the jailhouse doors in his or her own hands. Comply and be freed. Stay defiant and stay locked up. If you don't like it, you can appeal.
And if the person does not actually "posses the keys", sucks to be him. good luck proving that you honsetly do not know the password, that the money is really gone, etc.
Courts wouldn't work without civil contempt sanction.
Countries without civil contempt sanctions would beg to differ.
For flashblock, you can put a button to enable/disable plugins in your toolbar. Does not work as well as flashblock, but good enough. http://operawiki.info/CustomButtons
For adblock, I still have not found a good way to update my blocking list while keeping my modifications.
When the Soviets launched Sputnik 2 a small dog was on board. The dog had been trained to monitor the primitive electronics on board. Unfortunately the dog was not that good at monitoring the life support equipment and died of suffocation. The idea lived on though but now we use monkeys. They tend to be a little smarter and they can turn dials in addition to pushing buttons. Most commercial satellites now launch with monkeys aboard.
So, let's say that I am planning a big heist. How would I use this to foil investigations?
Gedtting some DNA is the easiest part. Cigarette butts for example
Now I need to somehow get access to Polymerase Chain Reaction chemicals and the primers used for crime investigation. How hard is that?
Then I have to liberally spread the PCR product around at the crime scene.
Or could I also use it afterwards when I am caught, by injecting myself with it, and putting it in my mouth, to taint any blood and saliva samples? Since the PCR product only has the specific DNA they test for, and in much greater quantity than in my cells, could the PCR product drown out my real DNA fingerprint?
Or is there an easier method? Could I simply spread some polymerase-blocking chemical at the crime scene to foil all PCR attempts?
Make him work as a waiter, or cold call salesman or some other crap drop until he drops dead. Every penny gets invested into a trust fund for children's education or some other noble cause.

Heat does not dissipate fast underground, but there is no way pumping heat underground in the summer will have any measurable change remaining in winter, is there? If you do it on a city wide scale maybe, but even then I doubt it. Heat pumps rely on the fact that the underground is generally warmer in winter and colder in summer than the surface.
Would my ISPs DNS server cease working? That server would no longer be able to access the root servers for.com,.net, and.org, but wouldn't it have all common names cached? And what about country tlds?
since the angular speed and direction of the ISS an other orbital objects is constant and known, do you even need fancy alignment correlation?
If you have precise timing for your shots, would it suffice to align the first and last picture, and the alignment of the rest can be infered from them?

Only if you are turning pages one at a time.
If you want to check what was written a few pages back, or want to skip ahead, or just flip through the book, an ereader is still terribly slow.
Granted you get the ability to search for strings in exchange, but still, this is what I miss most

Excellent bullshit. I'd give it a 4.7

So I'd have to inject the DNA just prior to showing up for my DNA test at the police, and hide some bit in a capsule in my mouth, breakable on bite.
