Why is so much unnecessary, security-risky, stuff connected to that device? In a worst case, have separate buses...
* the "entertainment" bus for wifi for "teh interweb", streaming audio, etc.
* the "critical" bus that controls car operation. Have it only *PHYSICALLY* accessable, i.e. only via physically plugging a probe into a jack. And none of the devices connected to the "critical" bus are radio/wifi/bluetooth/whatever-else externally accessable.

There are tons of hacks available.

If things get bad, an ISP could use CIDR on IPV6 for all their customers in a given city. A million customers in a big city could fit into a /64 with 2^44 addresses for each customer. If they're all in one city, routing would not be an issue for routers outside of the ISP's system. And, yes, I'm aware there's no provision for such stuff in IPV6... but then again, CIDR wasn't in the original IPV4 spec.

There's always the UUID bits to play around with.

And to really mess with IPV6 fanbois' minds, we could try NAT on IPV6.

You're in HR, interviewing a job applicant. Would you hire somebody who once offered his company's personal client information to a friend? And called his customers dumb? What if he said it was "a youthful indiscretion"? Like the following?

Reminds me of an Elliot Spitzer quote...

And never put anything in an e-mail."

He should also have mentioned never using prostitutes so expensive, that paying them triggers "money-laundering-detection" and gets the feds to investigate you. But that's another story.

Old fart here... AMD was cross-licenced by Intel to produce 80x86 cpus http://en.wikipedia.org/wiki/S... This was done because many businesses, especially government, insisted that the components NOT be single-sourced. Ironically, this cross-licencing agreement is what allowed Intel to legally use AMD64 cpu architecture, which Intel named "EMT64".

Linux nerd here... sorry, but I have better things to do with my time than worry about constantly patching and running smtp/web/ftp servers, and constantly monitoring logs, etc, etc, etc. Having a life gets in the way of an internet.

I have a reasonable idea of how vulnerable linux servers are on the open internet. It's mind-boggling how easily the average Joe/Jane Lunchbucket gets pwnd/social-engineered even with a client machine behind a stateful firewall. Give every one of them a server, and if you think today's botnets are something, you ain't seen nothing yet.

What are you talking about? Time to impact = distance-to-object divided by your current speed. Distance is obtainable by radar/sonar/whatever, and speed comes from the same tachometer connected to your car's wheels that provides speed info to the speedometer display. It self-driving-car shouldn't care or need to know what time it is. BTW, how would a GPS system operate in an underground (and/or underwater) tunnel http://en.wikipedia.org/wiki/U...

GM has a cold-weather test facility at Kapuskasing, Ontario, Canada http://www.wheels.ca/news/nort... Ordinary batteries tend to lose power when cold. Cold weather doesn't just happen in Canada, but also in a lot of the US "Northern Tier" states. E.g. Minnesota, Wisconsin, the North+South Dakota, etc. And let's not forget Alaska. Is there noticable power/range loss in cold weather with GM's electric cars?

Snowden's info releases embarressed the USA. But it is believed that several US agents died or were captured by other countries due to Pollard's espionage. The Secret Service is part of the US "intelligence community". Do you, as a former US president really want to pardon the man who was responsible for thr death of comrades of the people charged with protecting you?

Is that "less expensive" with or without massive subsidies? Gee it must be a nice racket;

1) produce 15% of the power you need
2) sell it to the utility for 8 times the market rate
3) buy back 100% of you power needs at market rate
4) Profit

In Ontario... http://www.theglobeandmail.com...

***
By the end of 2013, Ontario household power rates will be the second-highest in North America (after PEI), and they will continue to accelerate while they level off in most other jurisdictions. Even more alarming for Ontario's economic competitiveness, businesses and industrial customers will be hit by almost $12-billion in additional costs over the same period.

Such is the legacy of the provincial government's 2009 decision to establish feed-in rates, ranging from 44.5 cents to 80.2 cents per kilowatt-hour (kWh) for solar power, and 13.5 cents/kWh for wind power. These solar feed-in rates average 11 times the 5.6 cents/kWh paid for nuclear-generated power, and 18 times the 3.5 cents/kWh for hydro-generated power. The wind-power rates are more than twice as high as nuclear, and four times those of hydro.
