I think if you did this you would end up rocketing moped riders over the handlebars when it deploys.
Not to mention race replica sport motorcycles with much less than 5" of travel and very stiff suspensions.
UPS systems do use lead acid batteries...PLUS large input filter capacitors, and rectifier capacitors which have to be serviced every 5-7 years and can potentially fail catastrophically (boom) if you do not. I also work with large UPS systems for a few of our data centers, up to 300 KVA, and they are much more expensive, require more frequent maintenance, and don't provide the hours of holdover time you can get out of the same footprint of large VRLA or flooded batteries.
I work with DC power in Telecom and it has 3 huge advantages I can think of off the top of my head:
1) You centralize your rectification. Instead of having hundreds of power supplies running at 80% efficiency, you can have a large rectifier system running at up to 96%.
2) Lead Acid batteries are hugely more reliable and less expensive than equivalent UPS systems, and provide more holdover time. They're still expensive and finicky, but many times less so than a UPS.
3) Any old technician with a brain in their head can run DC power feeds to equipment relatively safely due to the low voltages involved. AC power work of any kind should have a qualified electrician involved.
Reporters deserve meaningless drivel because if you give them any real information they'll just butcher it in order to twist it into a cure for cancer or the latest exploit for iPhones in order to grab headlines. I'd look for firm dates and roadmaps provided to customers, partners, and investor relations as a sign that the company knows what they're doing.
I think the problem is that they are competing with Intel to beat them in massively parallel and IO limited applications. This doesn't look good on your average review site benchmarking the processor in Crysis or some PC oriented synthetic benchmarks. I think they're still going to be very popular for servers and supercomputers for a long time.
There would still be an incentive to keep performance/price increasing enough to keep the upgrade cycle going, it just wouldn't be as strong as if they had someone else pushing that same metric in competition. They could also control exactly what rate it grows at, and hold back their outstanding new designs until demand tapered off, then release them in order to obsolete the last generation and start the next wave of upgrades.
x86 is a subset of x86_64, or said another way, x86_64 is an extension of x86, just like SSE or MMX but with a lot more new instructions and hardware requirements.
It sounds like everything you do is x86. The alternative to that architecture isn't x86-64, it's Itanium-64 or ARM or any of the various big iron RISC chips.
What if the admin wants to do this intentionally to make internal resources available? Do you propose to limit the abilities of the regex in question to only make certain things possible? That doesn't seem like an improvement.
I agree with what you're saying about T-mobile. I switched recently and was shocked when the store employees didn't try and push any accessories or contract add-ins. They gave me the phone I asked for with the contract I asked for, and that was that. The coverage is comparable to what I had with AT&T and the data speed is fast enough not to be annoying.
I'm very pleased with the FCC swatting this deal down. I would hope that Deutsche Telekom could just spin off T-mobile to be a separate entity and keep a generous portion of stock?
Repsol Honda, Yamaha, and Ducati Corse are not going to be running stock engines, and are certainly going to be making more power.
The CRT bikes also are a far cry from stock engines, with modified bore and stroke and gear driven cams in most cases. The 1'41.5" that RdP ran yesterday in Jerez would have put him 4th on the grid last time the 990s ran there.
I suspect you're laboring under some misconceptions. I recommend reading David Emmets excellent CRT FAQ. http://www.motomatters.com/analysis/2011/11/22/crt_faq_everything_you_always_wanted_to_.html
I think you're hurricanes vs global warming prediction isn't a very good example.
As a motorsports analogy, I can't predicted who is going to win the first MotoGP race of 2012, but I can confidently say that the lap times will be faster than 2011.
Specific outcomes are always harder to predict than trends and averages.
Doesn't change the fact that you are spouting off urban legend crap with no technical basis in fact.
There are plenty of instances which show failures to recover overwritten data, zero successes. If the US government has to put your platters in an electron microscope, they're probably just going to hit you with a wrench instead.
If you actually try this, it will take forever to finish due to the/dev/random seeds being quickly exhausted. The computer will have to wait for new seeds from mouse inputs et cetera.
pseudo-random is also slow. /dev/zero or/dev/one is as fast as the i/o can work and just as non-recoverable for all practical purposes, urban legends aside.
If it's reversible, you do it. The fact is that if the hard drive read head writes a zero, the hard drive read head will read a zero, it will not read a 0.0003 and be able to speculate that it was once a 1.
The alternative to sanctions would be Saudia Arabia where you have terrible crimes against humanity and the perpetrators live like gods.
Just because it's not a panacea doesn't mean it's not worth doing.

And wasps. Wasps are bastards. Just bastards.

What you will get, however, is almost certainly diesel. They may put some of those other things on deck for show.

I suspect that the intended effect is mostly psychological (but no less real), and there will be plenty of outside ventilation.
The biggest accounting cost is when the accountants say "holy shit we lost X good employees and Y good customers when the AT&T thing was announced".

The EPA is around to protect the environment
And the TSA is around to protect us from terrorists. I agree with most of what you are saying, but your logic isn't going to convince anyone.

There are plenty of instances which show failures to recover overwritten data, zero successes. If the US government has to put your platters in an electron microscope, they're probably just going to hit you with a wrench instead.
There is also encrypted SNMPv3 which could be used to securely and reliably send short messages in a client/server architecture.
If you actually try this, it will take forever to finish due to the /dev/random seeds being quickly exhausted. The computer will have to wait for new seeds from mouse inputs et cetera.
/dev/zero or /dev/one is as fast as the i/o can work and just as non-recoverable for all practical purposes, urban legends aside.
pseudo-random is also slow.
And the command is dd if=/dev/zero of=/dev/hda1 given that the partition in question is hda1
