You joke but what is a meme (religions are "memes") really other than a self replicating piece of language? The *extreme* bits act in many ways like a virus does: self replication, performing specific tasks, adapting to their environment (like some of the more insidious malware) and neither viruses nor memes can replicate on their own; they need a "host."
Mckay had nearly driven her mad on the show as it was; could you imagine what would have happened if someone else as arrogant and annoying as myself were on the show as well?:)
That's fine for small scale operations but what you're essentially suggesting isn't feasible on the larger scale that He-3 production will need to be. We've got enough reactors that we get 20% of our power from them and there's tons of neutrons being emitted with nothing better to do than make TRitium for us.
They'll probably try to slip through some legislation under the guise of doing exactly that to stop the "terrorists" then it'll be used to harass anyone trying to cross the border for whatever reason they can think of at the moment.
If Debian just went poof, Ubuntu would still exist; it's just that the development cycle would likely take a serious hit. Either that or they'd pull a Linux Mint and completely rewrite everything to be based off of Fedora or something. Anyway to get this back on topic... The real problem with the Helium-3 shortage is Tritium which decays into Helium-3 over time. The government didn't anticipate needing truckloads of Helium-3 to detect nukes entering the country so not enough Tritium was stockpiled specifically to make Helium-3. We get most of the Helium-3 from our Hydrogen bomb stockpile which uses the Deuterium + Tritium fusion reaction. Since we didn't need much Helium-3 or Tritium, we didn't put the Li-6 + n => T + He4 reaction to good use but we can now. We also as the GP noted, have the option of using alternative detectors although their effectiveness may not be as high as Helium-3 based detectors. So in other words, it's an annoyance but not really the doom and gloom that the summary suggests.
I'm guessing there's also a shortage of Tritium which decays into Helium-3 with a half-life of 12 years. If you have enough Tritium around and wait long enough, you'll have fresh Helium-3. You can make more Tritium by exposing Lithium-6 to a high neutron flux like that found in nuclear reactors. The neutron splits the Li6 as LI6 + n => T + He4. Russia might have quite a bit of it laying around owing to the size of their nuclear arsenal that we could buy.
What is cause for alarm is the 13% of savvy pilferers who would take access and password codes as, with this information, they can still get into the network once they’ve left the company and continue downloading information and accessing whatever they want or need.
If the data is so sensitive, you'd think that a company would bother to change the passwords periodically so employees that have been let go can't get back into the system. However, security doesn't seem to be a terribly high priority so companies shouldn't be surprised when things like this actually happen.
Considering the Chinese government's history of headshotting and crushing opposition under tanks, if you lived in China and opposed what the government was doing, would you be in any hurry to advertise that fact? The Chinese government is in the business of suppressing dissent with any and all means available. Don't assume that the government's existence is indicative that it's what the Chinese people want.
If I remember correctly, F12 enables/disables javascript globally but not locally. You can't selectively disable javascript with F12. So if you go on a site and want to keep the site's javascript but not doubleclick's javascript, then you're SOL. Noscript is wasily configurable and doesn't need to be told every single time you visit a site.
Clearly you've convinced me of the wrongness of my position with all the profanity and ad hominem attacks. China has significant control over the connections to its borders. They will not allow their walled garden to get out of their control unless the people fight them tooth and nail.
Noscript,CS Lite, Adblock, menu editing features, scrapbook etc... You *could* block ads and control cookies and javascript but it's not nearly so clean as Firefox's addons allow. To me, Opera reminds me of Gnome. Things can be done but it's not really designed to do the job efficiency.
1) red flag linux and green dam. 2) Red Hat and friends could be restricted from offering support for their flavors of Linux unless X demand is met. 3) Maybe so but I felt that it was worth noting a few things.
The Chinese government is detrimental to their freedom. If the internet gets to the point where the Chinese government feels that it doesn't have control, they'll throttle the hell out of it until they can control it. Using Nokia and Opera and any other corporate entity to accomplish the task.
That's funny... I haven't heard anything about Firefox or Chrome doing what Opera did. Opera certainly had a choice. They chose to support the censorship in China in exchange for more market-share. Nokia and friends helped China to set up the firewall in the first place for the market-share too; are their actions excusable as well?
Linux doesn't go out of its way to please the Chinese government with its new update; Opera did. Linux isn't closed source either. The two aren't in the same boat here.
I have. It's on my system right now along with Firefox, Konqueror and Chrome. Addons are the critical component in which these other browsers than Firefox are very much behind. I would ditch Firefox in an instant if Chrome or Opera or Konqueror managed to be as flexible as Firefox but they're not... yet.
Even if it was, Chrome isn't in the same game that Fedora, Ubuntu and Opensuse are. Chrome is designed to rely heavily on net applications, the others are designed to rely much more on the desktop. Comparing them to Chrome is nothing less than comparing Apples to Oranges.

maybe... maybe not. Direct carbon fuel cells can have efficiencies topping out at over 70% and some can run on hydrocarbon fuels commonly used in aircraft. They have efficiencies higher than any combustion engine and far, far higher energy density than any known battery by a wide margin, Battery technology would have to improve *dramatically* to even come close to beating these.
very high efficnecy cells can have efficiencies over 60%. High temperature electrolysis can get around 60-70% electrolytic efficiency. For larger craft, the higher energy density of Hydrogen would start tipping the scale in favor of fuel cells owing to the weight reduction from not having to tow the extra weight of the lithium/sulfur battery material.
The Ion tiger has a 2.5 meter wingspan. The Qinetiq Zephyr has an 18 meter wingspan.
You cannot seriously be trying to compare the two.
Why not? Both can haul a ~5 pound load yet the solar/lithium*sulfur battery combo allows the 18 meter wingspan Zephyr to fly 3x as long. Swap out the battery for a fuel cell and an electrolysis cell and the craft might be able to stay up indefinitely. That is if we can ever get the electrolytic efficiency a bit higher than it is now.
The article didn't mention the craft having solar power as well to boost the amount of power available so it may still be the longest duration flight of any non-solar powered craft to date. Aircraft that use fuel cells + solar powered electrolysis have been speculated to be able to fly indefinitely if properly engineered. The solar power powers flight during the day and produces hydrogen from electrolysis and the fuel cells power the craft at night.
Yeah but how many people actually need a car that is specifically designed for those kind of environments? They fill a very limited niche that doesn't seem to overlap all that much with most peoples' driving needs. The range is far too short.
What benefits do these air powered cars have that aren't significantly exceeded by electric vehicles? The range of these cars is 1/5 of electric cars *and* is less efficient.
