Once they unify ARM kernels, the Zedboard PC featuring the Xilinx Zynq ARM/FPGA CPU should see even more and better development.
I'd love to see some porting of kernel functions into the FPGA, custom instructions that the kernel could execute in a flash rather than churn ARM cycles through. Is there a list of kernel bottlenecks that could be candidates for that kind of acceleration?
So now you can use Bitcoins to bet on things - that pays off in more Bitcoins. You have to give up real money to get the Bitcoins to bet, but all you can spend your winnings on is weed and socks.
I don't see why they can't recycle the beryllium liner after the implosion. Maybe not in this device, but in a fully production model, if beryllium is really scarce.
1. This is a very major milestone. 2. Depending on what you mean by "soon" (10 years, after waiting 50, for a change that will affect the next 100-100 years?), it looks like it will. 3. "Change our lives soon" is not a necessary standard for "news for nerds". 4. The word is "blurb". 5. You are a fool.
Because they exceeded the breakeven point with fusion, which is the second most important achievement other than eventually achieving huge energy returns on energy invested. That's the biggest news in fusion since the hydrogen bomb generations ago.
No, you don't believe, because you're an idiot and a slow learner. Achieving breakeven is the watershed. If you don't learn to accept change now, it's probably too late for you.
No, you're just equating Slashdot's "implications" to "end of the path". The implications are extraordinary, because the critical milestone is sustained production in excess of consumption, which seems to have arrived. The path from the breakeven milestone to the implied 1000x production rate is long, but far more certain than before breakeven is reached. Because breakeven is the threshold set by the laws of thermodynamics, the difference between just a big machine that's highly efficient, and a big machine that leaves more energy than when it started.
How much energy does it take to make the deuterium (heavy hydrogen) required for this fusion? Less than the surplus in the 1000x 60GA device? Maybe just the average energy to filter it from seawater? How much is that, compared to the fusion energy released from that deuterium?
Schools are the most productive investment we make. I disagree that we should structure 100% of kids' years into mandatory class time; unstructured or differently structured/spent time is better probably for most kids. But Summer classes are good for advanced kids who learn faster than most, and for kids who need more time (or just repetition). Spending that time makes them better people. Not just more productive, but also less destructive. All of which gains the society paying for the schools more production, which means more income, which means more taxes, which means more school funding. And less crime and other waste, which leaves more taxes (and more taxable work) to fund the schools. The economics are clearly a snowball effect, so long as the increased net production is properly managed (eg. fairly taxed according to benefit, and properly spread across the people who benefit even years later far from the school).
The only limits on the return on this investment are the capacity of kids to spend time learning, which for many could be year-round, and of course the education quality. The quality is an entirely separate issue.
We should have 9 hour school days, with every kid offered either remedial or additional classes during the Summer. The improved adults will pay for the schooling, and for everything else we do.
Far better than a longer school year would be a longer school day. School days currently are about 6 hours, ending in mid-afternoon, so schoolkids can go to work. That is a holdover from when workers competed with children in the labor market, which is generally not even allowed. Parents who got income from their kids were more willing to allow this new "school day" for their kids if they could keep working them at least part time. None of that is necessary or even useful anymore.
What's necessary is kids getting more time to learn. At the very least schools should give them an extra couple-few hours of supervised "homework" time (better named "exercises" or just more "studyhall"). More ambitious kids who study more subjects could take extra lessons in that time. Or extra time for other activities, especially art, music, shop, programming time spent learning how to express themselves by making things. The longer day would give teachers and other staff a full day during which they can work the overhead of their job, instead of always taking it home with them unlike most workers.
Perhaps most important, kids would spend more time at school than their parents generally do at work, so complete daycare is part of the service, even when parents have a relatively long commute.
We should keep the 3 month Summer break, but simply make it optional. The schools should be in service year round, including both remedial and accelerated classes during the Summer. But kids should be free to spend those 3 months entirely on elective activity. Take a Summer job, take extra (or repeat) classes, teach a class if they're really advanced, or just take each day as it comes if they're not juvenile delinquents. Leaving them to a programme of either their parents (especially when young) or their own direction, even if it's just goofing off with their friends, makes most of them better people. If not, and that shows in their grades, they should take remedial Summer classes.
All this goes for teachers, too. If anyone needs a few months break from unlimited responsibility (with severely limited power) over everyone else's brats, it's teachers. Or the best ones can make extra money working during the Summer session, too.
There is so much to work with. Schools typically are in session 180 days a year, 6 hours a day, instead of the 260x8 adults work. That's just about 52% of work hours spent at school. There's room in there beyond the traditional base school calendar to accommodate practically every individual student's needs. Including those able to hit at least a median education even just sticking to the original calendar, earning control over the rest of that ample time for something that isn't school at all.
I've been distinguishing "natural" from "human made" in every post in this thread.
A species in a habitat in which it previously did not live, to which it was transplanted by humans, is not natural. Until and unless the other species in the habitat evolve and adapt to a new balance - unless the evolution/adaptation is also executed by humans.
Again (and again), I am not making a value judgement by distinguishing between natural and not. Except that I will now say that natural habitats tend to be more stable than artificial ones, and generally more compatible with human existence (though there are plenty of notable exceptions of sustainable human activity).
Maybe not. In environments that evolved with fireants in them, genociding them will cause serious damage, possibly even collapse. Especially in environments already stressed by unnatural human interventions, from climate change and other pollution to simply trampling the ground.
What's the embodied energy of a modern class A RV? Seems like the cost ($ or Mj) of one of those is larger than a less efficient older RV that's already built so its startup ($, Mj) costs are paid.
Maybe so. Of course, if you just telecommuted from a permanently located dwelling you'd have even less impact.
Seems to me that a load of trunks brought along by train, loaded onto a local RV, is the best blend of conservation and mobility. Plus no driving - telecommuting from the train.
Yes, anything short of a hydrogen bomb is perfectly acceptable anywhere, so long as no homo sapiens are inconvenienced. And if it's no inconvenience, then an H-bomb is OK, too.

No, what got Saddam killed was having a country that would make Bush/Cheney cronies $TRILLIONS if the US invaded it.

This scam just gets better and better!

But since it costs $25 for a gram on Ebay, I doubt it's very scarce, since there's already a substantial demand from its other industrial and military applications.

You mean like PV panels orbiting the Sun? That's a terrific idea, and without having to build the fusor.

And that's why we don't have natgas cheaper than oil in this country. Wait...
Because you don't know the difference between perpetual motion and transforming matter to energy?
No, it'll just heat water, pressurizing it, that'll turn turbines that generate electricity. Like any large power plant, nuclear or otherwise.

No I don't. You need to stop shoving absurd hyperbolic excluded middles around in public.
Where is your question coming from? The distinction between "natural" and "human made" doesn't say where humans should or shouldn't be.
I've been distinguishing "natural" from "human made" in every post in this thread.
A species in a habitat in which it previously did not live, to which it was transplanted by humans, is not natural. Until and unless the other species in the habitat evolve and adapt to a new balance - unless the evolution/adaptation is also executed by humans.

There were borax mines everywhere there were campers? Every species in the Lower 48 was immune to borax? You've got a rounding error.
Maybe not. In environments that evolved with fireants in them, genociding them will cause serious damage, possibly even collapse. Especially in environments already stressed by unnatural human interventions, from climate change and other pollution to simply trampling the ground.
I can make install without installing war. You probably can to. Be the change you want to see, and you'll see it faster - and probably further.
And there are (therefore) no fireants, I suppose. Moot point.
It's not that borax isn't "natural", it's that even natural materials put into places that haven't adapted to their presence isn't natural.
