Startups run by 40 somethings are not news.
Startups run by 20 somethings are news
Therefore, most people believe that successful startups are run by 20 somethings.
We have read your request to "consider removing GTA IV from distribution 'out of respect for the millions of victims/survivors of drunk driving.'" Please get in line behind Jack Thompson, ESRB, the families of Aaron Hamel and Kimberly Bede, and thousands of other people asking the same request.
I remember one of my projects freshman year for a class called "Introduction to Engineering Computing" was to make a program that tabulated votes. I am not a computer science major and even I figured out how to make it work.
but if we use this stuff for fuel won't we be burning it right back into the atmosphere? The problem with the way we currently do things is that we are digging up carbon from the ground to be burned and never used again. This process could potentially mean we would have a closed loop. We burn carbon based fuel, then bacteria converts it into fuel through photosynthesis, and repeat. The net effect is zero.
In 2006, European astronaut Christer Fugelsang, a former Swedish national Frisbee champion, kept a Frisbee aloft inside the station for 20 seconds - thanks to the lack of gravity - to break the previous world record of 16.72 seconds for a single toss.
Combining this technology with algae after treatments like those used by GreenFuel Technologies and you have a true closed carbon cycle. Greenfuel uses sunlight and CO2 from power plants to grow massive amounts of algae. The algae grows rapidly because of high concentrations of CO2 and large surface area of the bubbletubes.
Get someone to reply to your post pointing out the biases of the modders, get modded back insightful. Ironically, higher than the original post.
More ironically, that someone is the original poster. Moderators, pay attention to nicknames! This social engineering must stop NOW!
This isn't really using the pressure of the solar wind for propulsion; rather it generates power from it which it then uses for propulsion. Neat idea. That's not how I read the article. I read it as by charging a bunch of wires it increases the effective area of the solar sail. Therefore there is no need to make an entire physical sail.
Sure, you can use just about anything for fuel. The problem is, different fuels have different physical properties. Specifically, they have different combustion properties.
An example is ethanol. Ethanol is an excellent fuel despite the fact it has a lower specific energy (J/kg) than gasoline. Ethanol is more resistant to auto-detonation than gasoline, which makes it resistant to what mechanics call "knock". This resistance to knock enables engines burning ethanol to operate at higher compression ratios. High compression ratio engines are more efficient and therefore offset ethanol's relatively low specific energy. However, high compression engines lose the ability to burn regular gasoline. This is not an acceptable tradeoff to most consumers and therefore so called "Fexfuel" vehicles get very poor mileage on a tank of E85.
Biodiesel has many more problems. Where E85 is made from only corn, biodiesel is made from a variety of raw materials. Therefore, the properties of the biodiesel vary wildly from one tank to the next, making efficient combustion nearly impossible. The type of biodiesel used could result in increased oxides of nitrogen emissions (NOx), rapid lubrication oil degradation (more frequent oil changes), or engine damage.
The bottom line is, for a fuel to be practical, it has to have consistent physical properties.
I doubt you would actually get protection by joining a good botnet. The bad botnet will likely attack the good botnet and take out at least a few of the machines (temporarily). A machine in a good botnet is about as secure as any given fish in a school of fish.
But it is the solution! If an internet protocol is developed that requires each machine that wishes to connect to a website to use a few computing cycles to do something constructive, like BOINC, we could make massive advances in science and technology in no time! By doing so we could harness the power of the botnets to do good.
Using another botnet to send puzzles to the first botnet before it is allowed to access the main server works on a small scale. But think about it this way. If you have two networks sending massive amounts of useless data across the interweb. The ordinary users (whether they are members of a botnet or not) will suffer. Network traffic will slow to a crawl globally (I suspect it already has due to botnet activity). This will result in a MAD scenario reminiscent of the Cold War. Global network traffic will become nothing but noise.
From what I read here this device does not add any more security than "software" based encryption (it's still software based, if you think about it). The only advantage is that it relieves the CPU of the tiny amount of clock cycles that it would normally use to do encryption.

Too late...
I always think of Nimrod when I think of self repairing robots. Perhaps I read too many comics and didn't watch enough TV.
There, fixed it for ya!
I believe you are 100% correct. Storm "subsides" just as this "new" botnet appears. The botnet operator just upgraded to version 2.0.

Say something bad about Apple and American cars and get moded a troll. Says something bad about Microsoft and get +5 insightful.
What do I care, I have karma to burn.
because the business model includes making the product fail often enough that the consumers will constantly have to buy new ones.
It used to work for cars until this company called Toyota came along and ruined everything. Maybe I'm just cynical.
I can now install hypervisors without rebooting the victim's... I mean... client's computer?

If you repeatedly use the same public terminal with this device, can one eventually determine the master key?

From what I have seen, a side effect of some electromagnetic railguns is that they melt the projectile upon firing.
At what point does electrically charged molten metal become plasma?

If the hammer doesn't work, get a bigger hammer.
Always be worried when you see someone that works with computers carrying a 30 pound sledge hammer with a big smile on his/her face.

If it doesn't matter where the encryption takes place, what is the purpose of this device?
