> Data compression on the other hand is a different domain.

Why ?
Data compression has been used since a long time, think about stenography or shorthand, for example. This is a manual data compression system, no computer required. Many algorithms are only practical on a computer, but they still are mathematical algorithms.

I had a SGS2 and have a SGS4 now. They are fine phones. I want a replaceable battery and a SD card slot. This reduces the field for me a lot.

For my wife I bought a Moto G and I suspect I will replace my SGS4 with a phone in the same class, once it needs to be replaced. Phones are rapidly approaching the phase where most middle class phones are good enough. Two years ago a high-end device was necessary for a good experience, these days this is no longer true.

Life will become tougher for phone manufacturers.

>The carrier has the choice to implement ipv6. Run ipv6 natively, and tunnel ipv4 traffic.

I don't think this will solve the problem. In the end, even if tunneling, some applications expect to see an IP per end-user. So the carrier still has to expose a dedicated IPv4 address per customer to the internet.

No. He will have to pass the additional cost of the IP addresses to its customers. And those customers are not ready to pay the price. They prefer a cheaper, but crappier service, otherwise the'll upgrade or switch to another more expensive carrier with real IP addresses.

The carrier has probably no choice. He can no longer get IPv4 addresses for new customers, so either he refuses customers or uses NAT to map multiple customers on the same IP.

On the other hand, the average Joe customer will not see the difference. He can surf as before and all his apps will work as before. Some apps (mostly p2p stuff) will suffer, but most internet user don't use those.

If you as customer do need a 'real' IP, then there always is the option to get a more expensive option.

I agree, I find this an excellent password recovery scheme. It does not protect against a bad choice in friends, but there are no technical protections possible against that. But for password recovery it is very good and quite safe against abuse by anonymous internet hackers.

They are actually working with rats at this time. The first couple of years that compiled a database of rat-neurons in detail: Form and function. They do test the simulation extensively: Connecting electrodes to the synapses to check out what combination of input signals cause what output signals. After wards they look at one of the brains building blocks: The neuronal column: You assemble 10'000 neurons and do the same again: Feed it input and verify the output. If the simulation and the real thing gives the same result, then your simulation is ok, otherwise you go and tweak it until you get the same results.

I don't know how they go about Human brains, I'm sure they can not easily compare the simulation with the real thing. There are no volunteers to give op a bit of brain to feed the experiments :-).

They also are the main user of a BlueGene supercomputer at EPFL to run the simulations.

We'll see where they get over time. Henry Markram, the project leader is excellent, so I'm confident.

This event dates from late September. As far as I know he was caught, before he could sell anything.

But, the Swiss Secret Service was lucky: The guy was caught because his bank became suspicious when he wanted to set up bank accounts to receive the future price for the loot.

The guy essentially walked out of the place with disk drives full of data. As he was the IT maintenance guy, he could pull this off without anybody getting suspicious. If your IT guy replaces 'broken' disk drives, everything is ok, other employees thought. As Switzerland is small, that department was small too, so there was a lack of resources.
