Comment Security Clearance Revocation (Score 5, Insightful) 676

Any normal person would have their security clearance revoked after a breech of much lesser magnitude, which interestingly makes you unable to perform a job that requires handling classified material, it's one of the few ways to actually get fired from a government job.

Just another facet of our societies aristocracy, they are above the rules. (note this has nothing to do with party, both side get far too many free passes)

Submission + - Scientists identify possible new substance with highest melting point

JoshuaZ writes: "Researchers from Brown University have tentatively identified an alloy of hafnium, nitrogen and carbon as having an expected melting point of about 7,460 degrees Fahrenheit (4120 Celsius). This exceeds the previous record breaker tantalum hafnium carbide which melts at 7,128 F (3942 C) and had stood as the record holder for almost a century. However, at this point, the record setter is still hypothetical, based on simulations. The new record has not yet been confirmed by experiment. http://journals.aps.org/prb/abstract/10.1103/PhysRevB.92.020104 is the actual article while http://www.washingtonpost.com/news/speaking-of-science/wp/2015/07/28/behold-a-new-record-for-the-worlds-highest-melting-point/ is a lay summary. If the simulations turn out to be correct, the new alloy may be useful in parts like jet engines, and the door will be opened to using similar simulations to search for substances with even higher melting points or with other exotic properties.

Submission + - Slashdot for Sale (again) 4

Defenestrar writes: DHI Group (formerly known as Dice Holdings) will auction off Slashdot and Sourceforge. The stated reason for the sale is that DHI has not successfully leveraged the Slashdot user base.

Comment Africanized Killer Bees (Score 2) 225

Bring in the undomesticated bee strains as pollinators.

The European /North American bees have been bread for docility for centuries to the point where we transport hives on trucks to pollinate where needed, is it any wonder that they are not migrating "naturally" they are for all intents and purposes domesticated, it's like expecting cows to migrate on their own.

I would expect that so called "killer" bees would be adapting better to climate change.

The problem with modular addition is that the power conditioning equipment and professional installation required to sell back to the grid tend to cost several thousand dollar, regardless of the amount of energy your selling back.

Starting small can work if you want to play around with it yourself, but when you connect to the grid you get into big trouble if you don't meet all of the utilities requirements.

Comment Radioactive Fuel... (Score 1) 486

This reminded me of some of the plowshares experiments (where they tried to come up with non-war uses for hydrogen bombs) Link

One of the ones I remember being interesting was the use of underground detonations to break up rock and free natural gas (think super-fracking), it was tested and worked with only one problem, it was horribly inefficient and not cost effective, oh and all the natural gas was radioactive. As with all the plowshares crazy ideas this one didn't quite pan out, but it amazed me that they actually tried it. Oh and just to be sure they did it 3 times.

In the pacific northwest (Seattle Area) my calculations show break even at around 18 years, which is pretty bad given that, the panels are only usually rated for 15 years.

Every few years I get to thinking about doing it and I run through the calculations and come up with similar numbers, panel prices are down, but power conditioning set-ups are still a big part of the cost, and then you have to pay for a contractor to install the setup (one of the largest parts of the cost) if you want to get any of the tax credits or connect to the grid.

Looking at my last utility bill, 99% of my energy is coming from non fossil fuel sources, hydroelectric mostly. So green guilt is not going to get me to put PV on my house and it doesn't really make economic sense either.

I'm sure I'll run the numbers again in a few years when I need to re-roof the house; I like the idea of energy independence, but where I live Solar PV is just not cost effective.

Comment Diablo?? (Score 1) 73

It targets files associated with single-user games Call of Duty, Star Craft 2, Diablo, Fallout 3...

Seriously Diablo?? WTF is that a typo and supposed to be DIablo II or 3, are people still playing single player Diablo, a few years back I installed it in a VM to get some nostalgic gameplay and it was horrible.
