+ - Killer whales caught on tape speaking dolphin->

Submitted by sciencehabit
sciencehabit (1205606) writes "Two years ago, scientists showed that dolphins imitate the sounds of whales. Now, it seems, whales have returned the favor. Researchers analyzed the vocal repertoires of 10 captive orcas, three of which lived with bottlenose dolphins and the rest with their own kind. Of the 1551 vocalizations these seven latter orcas made, more than 95% were the typical pulsed calls of killer whales. In contrast, the three orcas that had only dolphins as pals busily whistled and emitted dolphinlike click trains and terminal buzzes, the scientists report in the October issue of The Journal of the Acoustical Society of America. The findings make orcas one of the few species of animals that, like humans, is capable of vocal learning—a talent considered a key underpinning of language."

Well said. You saved me the trouble of writing a comment not half so clear and complete.

Ask professional drivers. These "ethical" questions are ridiculous. Avoid obstacles if possible; if not, slow down. It's better to crash into something you can't avoid as slowly as possible. It's also best to maintain control just in case the situation changes.

So, what are you going to use for ID?

So, in that atmosphere, how any single website would ever be able to "authenticate" your ID, I have no idea.

How about tamper-resistant cryptographic biometric devices? Use your government-issued fingerprint reader to log into Big Brother's system, then each server is required to make sure you have a valid current login certificate from BB before providing any services. Complete records must be kept indefinitely and will be audited against upstream connection logs.

Nobody is required to have government ID, but network service providers are prohibited from communicating over the Internet with anybody who isn't logged in with Big Brother.

Obviously this only works within one jurisdiction. Foreign Internet users would have to be handled separately, if at all.

I guess it would be easiest to manage this at the ISP level -- ISPs would be required to require proof of identity (via secure biometric reader) at regular intervals from all users. Then you don't necessarily have to bother auditing web, email, etc, servers.

IMO, if ads stopped across all internet sites, or the online advertising industry completely collapsed. The internet as we know it, would be gone.

Correction: The Internet as you know it would be gone. The actual Internet would be just fine. Universities, stores, hobby sites, government, and people generally interested in communicating with each other would pay their ISP bills and continue without interruption.

Turing's imitation game was a thought experiment. To explain it simply to an audience unfamiliar with the idea, he started with man against woman, then proceded to man against machine. The specific genders were not important or significant in the thought experiment, just the existence of some difference between the contestants that could potentially be spoofed over a teletype. There was nothing gender-specific or weird about it.
