Sheesh. It's not that toxic, unless you drink it. It's not "readily absorbed through the skin"; the MSDS for it says it is only a skin irritant, which is the case with any alcohol. It can be absorbed through the skin, or course, but only with prolonged contact. It does not seem to be significantly more dangerous than most household chemicals. Considering that it will be in a sealed cartridge, I don't see the big deal.
Exactly. The maximum possible thermodynamic (Carnot) efficiency for a car engine cycle is in the 30% range. This does not depend much on engine design or anything else for that matter, just the combustion temperature and the dead state (air) temperature. This is very basic physics.
Combustion efficiency in a properly working car engine should be very close to ideal under normal driving conditions. Furthermore, CO2 is one of the products of an ideal combustion process. Unless you aren't using gasoline for fuel and/or don't have a catalytic converter, you will emit the same amount of CO2 per gallon of gas used. Finally, if you have 5.5% CO2 in your exhaust, you're not burning anything. That's close to the atmospheric value.
This is simply a scam. People have been trying to create perpetual motion machines for thousands of years. What's sad is that this makes it to Slashdot in this day and age.
I'm sure that if Microsoft's behavior was well-documented, the kernel would work the same way it did. The problem is, there are no good specifications on what windows does. The bios manufacturers don't obey the specs, they just tweak their bios until it works with Windows.
How else could the engine accelerate? Gas burns at the same rate wether you have 1 part fuel or 20 parts fuel
Huh? If you have more gas and more O2, it will produce more energy when it burns. When this energy is converted into rotational energy, the engine accelerates. Spark advance has nothing to do with it. Diesel engines don't even use sparks, and they work fine. Lawnmower engines don't have spark advance, and they manage to accelerate (from zero) just fine.
Bose's "original" cabinet designs are mainly snake oil designed to appear impressive to those unfamiliar with the relevant theory (i.e. just about everyone). At best, they are an attempt to compensate for the shortcomings of the drivers. This would be justified if the speakers cost $150, but not when they cost $2500.
The fact that you have to replace drivers with aftermarket ones means the speakers could not have been correctly designed. A speaker should be tuned to a particular driver's parameters for it to work optimally.
The problem with Bose is that they use various filters and electronics to make cheap, crappy drivers sound better by accentuating a few bass frequencies and turning up the midrange. The problem is, this still sounds like shit compared to a decent set of speakers. The only good reason I see to buy Bose is if you really don't have the space for a proper set of speakers. They do sound much better than anything else you can buy at Circuit City, but you can get much better speakers for the same price.
On linux, this pastes whatever is on the clipboard into the tab as a URL. They really need to rethink the whole close tab feature, really. Plus, what's up with moving "close tab" to the very bottom of the context menu in 1.5b1?
I second that. Visio works very well for network stuff. There are even libraries of network equipment pictures/diagrams that you can put in. Photoshop is a horrible tool for this.
When the engine is idling, it uses up just enough fuel to overcome the internal friction and keep running at a certain RPM. If you load it down with a generator, it will use proportionally more fuel, and you won't gain any fuel efficiency.
I don't think it's possible to get regenerative braking with this device. To do that, you would have to decouple the gas engine from the rest of the system. Since this system attaches to the crankshaft, it won't be able to extract any energy from braking because either the transmission will disengage the engine from the wheels or you will get regular engine braking. In either case, the electric motor won't extract any power.
Even factory-made hybrid cars don't get 15mpg over the straight gas-powered one. Ask anyone who owns a hybrid Accord. The EPA estimates are way off; the actual difference in mileage between the two versions is very small.
This product will be fairly useless, because it seems to just drive the engine crankshaft, and is powered from supercaps. There are three major problems with this approach: the amount of energy the capacitor can store is very small, the electric motor will have to work against the gas engine's compression, and you won't even get regenerative braking because the transmission will just downshift when you slow down. This device is very unlikely to increase gas mileage.
Firewire is expensive. It's a complicated protocol and requires extra chips and a powerful processor for interfacing with it. This also makes it bigger. For a small device like this, you can't really afford to fit a huge firewire controller in there, and it would also eat at the bottom line. USB2 is much simpler and is very cheap to add compared to firewire.
Well, Firefox has 0 unpatched vulnerabilities right now (this one was patched recently). Not to mention, Opera is closed-source, so who knows how many bugs it has.
If you are looking for a 100% secure, bug-free browser, you won't find it. Get over it. Microsoft releases fewer patches mainly because they sit on their asses longer. There are still many unpatched vulnerabilities in MSIE. The main difference between MSIE and Firefox is that you don't have to spend days cleaning out spyware if your users use Firefox.
The problem with this approach would be that the free software movement is much smaller than the software patent movement. The GPL's patent clauses are already too strong for companies like IBM to consider using it, and making them stricter would not accomplish anything good.
Let me put it this way: ANY such study is 90% bullshit. Only YOU can evaluate which solution is best for your organization. If I need something mission-critical and/or high-performance, both Linux and Windows are out of the question. If I need ASP.NET for whatever reason, the OS choice is pretty easy.
See that "tr.v."? That means "transitive verb". Which means that the phrase "has an affect" is incorrect. The word 'affect' can be used as a noun, but then it has a completely different meaning. The correct way to use 'affect' is in a phrase like ' affected the profit margin'.
Missouri law also makes it illegal to possess, say, gloves and a flashlight (or any other tools which can be used to assist in a burglary) if you know burglars use such tools. Sure, you probably won't get prosecuted unless you actually get caught trying to break in, but there is nothing in the law that actually stipulates that, as far as I know.
Here's a quote: 569.180. 1. A person commits the crime of possession of burglar's tools if he possesses any tool, instrument or other article adapted, designed or commonly used for committing or facilitating offenses involving forcible entry into premises, with a purpose to use or knowledge that some person has the purpose of using the same in making an unlawful forcible entry into a building or inhabitable structure or a room thereof.... (1984) It is not necessary that the tools be "breaking" tools but only that they be adapted, designed or commonly used for committing or facilitating offenses involving forcible entry into the premises. A flashlight and a pair of gloves can qualify as burglar's tools. State v. Adkins (Mo.App.), 678 S.W.2d 855.
I don't really think it's worth incorporating fast-changing technology directly into the cirriculum. It might be a good idea for a few classes, and it's nice if the teacher can use it, but it's hard to expect every math teacher to learn all that stuff and keep relearning it every 2 years.
Not to mention, the usefulness of this is at best dubious. If you know the basic statistical theory, the only thing you'll really need to do would be to hit F1 and find the appropriate section of the manual. Computers or calculators are certainly useful for statistical experiments, but a good theoretical foundation is much more important than the practical ability to perform statistical tests. Considering how fast technology can change, the shelf life of that knowledge is maybe 5 years.
Not to mention, statistics is the only high school class where the computer can be a useful tool and not just a way to avoid learning the material. Something like Mathematica or Maple or a TI-89 might seem like a cool program for a calculus class, but it lets you do get through calculus just by learning which buttons to hit.

You are right, I did not remember the numbers correctly. It's actually around 0.04%, though it does vary significantly.

Well, the university doesn't really need YOU, either.
Maybe you should try it, fucktard.

The equation is correct. I think the point the grandparent wanted to make was that the equation is irrelevant. I would tend to agree.

No, dude, the RFID part is what's expensive. I can get it to output in RS232, USB, or any other format with a $1.50 microcontroller chip.
