Vehicles have to have motors that are way more powerful than is needed at cruising speeds in order to handle acceleration and changes in altitude.
Electric motors are cheap compared to the other parts of the car anyway, and doubling the power does not double the cost. As an additional bonus, a more powerful motor is also a more powerful generator so you get better regenerative braking.
That's why cars with turbos are a waste for most consumers, beyond the status symbol aspect. Unless you're willing to kick back two gears when overtaking and go ahead and overtake 5 cars at a time when doing so, you'll never really get much boost out of it anyway. All a turbo does is even more dramatically increase the power output at high RPMs that most people don't like to operate at
The thing is, people like having a lot of power available, even if they never use it. Some even feel safer knowing that they can accelerate fast if they have to. Therefore they buy large engines and run them at 10% or less most of the time. If we can get them to accept turbo engines, we can give them 1l engines with 200hp. This saves a lot of fuel; gasoline engines are terribly inefficient unless you run them at close to 100%.
Of course the holy grail is electrical compression, that should make the turbo lag imperceptible.
Even if SQL wasn't an issue, you still have to sanitize other things like shell commands.
No you don't. You have no reason to call the shell -- you are already using a programming language which is surely more capable than a stupid POSIX shell! (If not, you REALLY need to switch languages.) Call the program directly without invoking the shell.
This is a bit of a misfeature in Unix / C; system() is easy while the right way requires you to do fork() and exec() by hand. There is no reason to repeat that mistake in modern languages.
The main UK problem is that backhaul from the exchanges is very expensive (and metered, believe it or not) unless you put equipment at all of them. This makes it almost impossible to compete with the few carriers who DO have equipment at all exchanges. Therefore broadband competition only exists in the cities where you can get enough subscribers that it is worth putting in your own equipment. Then add FTTC, where it is impossible for more than one carrier to put in equipment. There simply isn't room or power available for each carrier to be able to put in their own DSLAM in a cabinet, so competitors are forced to use the expensive and metered lines from the main carrier.
The result is that service in the rural areas is slow, expensive and metered, and service in urban areas is either cheap and slow (ADSL2+) or fast, expensive and metered (FTTC).
Just to make it worse, it is legal to tie customers in for long contracts. Right now BT won't sell you an FTTC line for love or money unless you indenture yourself for 18 months.
1Mbps in 2001 was dead slow, sorry. 100Mbps ethernet was everywhere and 1Gbps ethernet available. Computers could easily fill a 100Mbps connection while 1Gbps was more of a challenge.
There is no technical reason for consoles to not support Suspend-to-RAM. That would drop the idle power below 1W -- well it wouldn't, because the idiots can't even make a console which is turned OFF use less than 1W. But for the next generation they will have to fix that bit at least, because otherwise the consoles will be illegal to sell in the EU.
You really should stop doing that, unless you happen to live in Iceland. In normal climates, it is trivial to get twice as much heat from a heat pump compared to the electricity it uses, and more than 3 times is not unusual. Even Greenland is starting to use heat pumps.
(Iceland happens to have an approximately infinite amount of cheap hydro power available and a lousy climate for heat pumps. That combination is exceedingly rare.)
TVs have reached a maturity point again where tomorrow's new model doesn't really have much over today.
It's funny, I think TV development has accelerated massively. True, the picture quality does not change much, but the number of extra features you get every year is amazing. The screen sizes are increasing as well, if you are into that kind of thing.
Soon TVs will be able to offer the features of a high-end smartphone or tablet.
I think that may be right but I'm not sure, how do other industries cope with this? e.g. Mining? Chemical Plants? etc
The same way nuclear does: There is a disaster somewhere and safety standards are improved. Somewhere between a decade and a generation later the lessons are forgotten, and there is another disaster somewhere. Most of the nasty mining and chemical accidents happen far away from the western world though, and they rarely get more than a brief mention in the papers.
The economy and passenger ships work the same way. Except it seems that when it comes to the economy, memory lasts only a couple of years.
/48 was the originally envisioned minimum end user allocation. It has been changed to/56 because some ISP's are afraid of running out of addresses. A typical ISP is assigned a/32 unless they ask for more, so that is "only" 65000 customers. However, large ISP's have been assigned up to/19, which leaves room for half a billion subscribers, even with/48 assignments. Going to/56 bumps that to 137 billion subscribers...
Yes, 4to6 looked good ten years ago. Now we have DNSSEC and faking DNS records looks a lot less attractive. It's fine if you have a random box in the corner which can't be upgraded to support IPv6, but for general deployment it doesn't really cut it.
But for most of us, all we'll need is an IPv6-capable router/modem at the Internet gateway. Inside the facility, who cares?
You are planning to run IPv4 on the inside NAT'ed to IPv6 on the router? This is doable but somewhat tricky since you need to fake DNS. You won't get any of the IPv6 benefits, of course.
I doubt it will be a particularly popular deployment model. Putting complexity in the CPE's which are already behind schedule to save trouble for the client systems which have been ready for ages seems somewhat backwards.
They're banned in my country (Sweden). We're now awaiting the mercury increase leaking from garbage dumps..
Clear halogen bulbs with the same shape as the old bulbs are still allowed. To quote from the GP: "Claiming that light bulbs have been banned, even incandescent ones, is simply showing ignorance, and or an agenda of misleading others." This applies to Sweden as well.
We aren't talking major sacrifices. Not at all. We just need to get our asses in gear and build either renewable or nuclear power stations to replace the existing power plants, which in most of the world are up for replacement anyway. At the same time we need to get fuel efficiency of transport up, and we need to get rid of the worst ways of getting fossil fuel (which have a fairly bad energy balance anway), such as brown coal and tar sand.
The economy is in a completely stupid state right now. Paying people to dig holes and fill them up again would improve the economy (as long as they don't expend natural resources while doing it).
There are lots of unemployed people. Surely some of them can make something which will help lower CO2 emissions.
And yes, 16:9 because keyboards aren't tall enough for 4:3 on a laptop. The extra width is "free", it brings a wider and therefore more useful keyboard. Extra height on the other hand just makes for a larger laptop and then it's better to just go 15" and wide screen again.
If you build it, they will come. Get the sh...stuff out there in the market and if it doesn't work, people will demand solutions. It's true with anything else, from hard drive size limits to 64-bit drivers. The stuff that doesn't add support will wither and die as it should.
I don't believe many will come. I know way too many people who are willing to pay a bit extra for a lower resolution so everything is bigger.
The only chance higher resolution has is the Full HD label.
It doesn't do TV yet though it is planned and being worked on (forever).
You can turn a TV capture card into a streaming source with HTS Tvheadend, which is very easy to set up. XBMC speaks the Tvheadend protocol, so it works fine for live TV.
What you can't do is control recording etc. from XBMC, unless you use the PVR branch which is indeed being worked on forever. For that you need to use the Tvheadend web interface.
You can't do that. Any non-reversible computation causes an increase in entropy, and reversible computation is not particularly practical. Achieving practical reversible computation would be a leap at least as large as room temperature superconductors.
Can I take my Bible into Saudi Arabia? Yes, you are generally allowed to bring your Bible or other religious items with you as long as they are not intended to be used to try to convert Muslims.

The Pentium II should have no trouble filling 100Mbps ethernet, even at 233MHz.
1Mbps in 2001 was dead slow, sorry. 100Mbps ethernet was everywhere and 1Gbps ethernet available. Computers could easily fill a 100Mbps connection while 1Gbps was more of a challenge.
Same goes for putting a turbine on the roof, the drag costs more energy than the turbine can produce.
Strangely, wind turbines on top of cars CAN work, at least as long as you have a head wind or a side wind.
They probably want to create something which could theoretically deliver half-decent performance.

I heat my house with electricity.
You really should stop doing that, unless you happen to live in Iceland. In normal climates, it is trivial to get twice as much heat from a heat pump compared to the electricity it uses, and more than 3 times is not unusual. Even Greenland is starting to use heat pumps.

Does not matter. Because once it hits the VoIP with PoE for their phones it will be knocked down to 100Mb/s anyway.
That is purely because the particular phones only have a 100Mbps switch built-in. There are plenty of PoE VoIP phones with 1000Mbps switches.

Not on an 10"-13" screen, and it's iffy on a 15"
Why not? I would love to have 1920x1080 on a 13".
And yes, 16:9 because keyboards aren't tall enough for 4:3 on a laptop. The extra width is "free", it brings a wider and therefore more useful keyboard. Extra height on the other hand just makes for a larger laptop and then it's better to just go 15" and wide screen again.

100% computational efficiency, 0% heat release
You can't do that. Any non-reversible computation causes an increase in entropy, and reversible computation is not particularly practical. Achieving practical reversible computation would be a leap at least as large as room temperature superconductors.
More measurements won't help you with a coin toss
Of course they will. The effects of quantum mechanics on something as large as a coin are insignificant.
