I mean seriously, you only need to account for the real time space-time relationship of two objects, it doesn't matter how they're moving, the fractal differential equation is the same.
What the hell is a fractal differential equation? Maybe you meant a partial differential equation but I'm guessing that, at worst, the mathematics boils down to integrating out an ordinary differential equation .
It drives me crazy that battery capacity is quoted everywhere in milliamp-hours (mAh)! Why can't everyone work in joules, so that we needn't constantly convert for voltage?
You can take a MOOC on quantum physics. No need to remain ignorant...
In my opinion, the only people who can learn much from a MOOC are N00Bs.
(I'm being flippant, but give me a break. A MOOC in quantum physics, without underlying groundwork sufficient to understand, say, what a Hamiltonian is, couldn't possibly yield more than a superficial picture.)
I know! Let's explain the workings of a deterministic computational system using analogies to quantum mechanics! Everyone find quantum mechanics clear and intuitive.

This outcome is exactly what the Librarian of Congress sought when he withdrew the DMCA exemption for cellphones, and I'm thrilled it's working out like this. Many people here complained at the time, but it was obvious to many others how useful the withdrawal would ultimately be.
Had he continued the exemption, the cause of locked hardware would have remained uninteresting to the public, and ignored by Congress. Now, we have a fighting chance at rational legislation.
Where the savings really went? To YOU, the customer. Yes, really. Why do you think the quality of life has improved so much over the past decades? It's because productivity has increased so much.
Actually, over the past few decades I would have said that the quality of life had deteriorated, except for the top few percent. Shiny geegaws, yes, they've improved.
Oh, please. We have far less crime, longer lives, safer cars that take less gasoline, better and more varied food, and (for those of us in developed countries) walk around with access to most of human knowledge in our pocket. Life may not be perfect but it's a damn sight better than it used to be.
My cars, OTOH, are much more expensive to keep around. Local ordinances require all vehicles to be licensed or stored in a garage. And licensing requires maintaining insurance.
For the 1970 car in Michigan, historical plates are $30 every 10 years. I don't recall the extra insurance costs, but those are relatively small too. (The car is uninsured and garaged for half the year, which helps).
it'll ultimately fade away again because like the muscle cars of the era they were cool but just cost too much to keep.
Oddly enough, I have both a 1996 pinball machine and a 1970 muscle car. Not that I'm arguing the maintenance on either is easy, but they are not expensive -- probably under 50th percentile as far as hobbies for Americans go. Both have low or negative depreciation, and $100-$1000, plus 5-10 hours of my time, per year. I spend more on bicycling.
It we be very cool (and intimidating as hell) if it turns out that galaxy has been engineered this way by some advanced alien entity. I guess we'll know in a few thens of millions of years when it does (or doesn't) turn elliptical.
As a mathematician (now in industry) who knows many other mathematicians, I can assure you many of them are very poorly prepared to handle data or real-world problems.
I agree with you from a price point of view, but workflow efficiency is very important to me, moreso than workstation power.
At one of my jobs, a powerful Linux workstation is my primary machine and we use a Linux compute farm, so I am keenly aware of the shortcomings of both the Linux user environment and of the hassle involved in dealing with remote jobs. If one doesn't have a very wide variety of calculations, or the calculations rarely change, then remote is no big deal. Otherwise it is a real time sink.
If you're doing numerics, what the fuck (if you'll pardon my French) are you doing buying Apple?
Fair question. It turns out, PDE solving etc. isn't all I do, so while I like my machine to be reasonably fast at the numerics, I require it to work well as a general-purpose computer, too. To me, Windows, Linux and FreeBSD fail to meet that criterion.
I do small-to-medium problems locally without having to think about remote execution issues, and then farm truly heavy numerics out to parallel processing farms like anybody else (aside from the PDE solvers, much of what I do is embarrassingly parallel). It's really quite nice, say, running some giant calculation in Mathematica or Matlab and then being able to click-n-drag the output plot into presentation software. That workflow is unavailable in Linux, and probably full of pitfalls on Windows.
[Same answer to the poster who wonders why bother to wait. ]
I hope there's really a new Mac Pro coming and that it has these chips in it! I do a heck of a lot of PDE solving, statistics and simulations, and would love to have a screamin' machine again.
Linux still feels pretty 1990s to me. I use Debian all over the place for servers, but if you want
- CUDA or OpenCL
- iPhone syncing
- advanced audio
- multiple monitors
then I hope you like playing with drivers, and xorg.conf, and automake. Because that's going to be a few days of your time.
France taxes at a rate of (roughly) 51% of GDP and spends at 56% The USA taxes at 32% and spends at 42% (2010 accounts) UK: taxes at 40% and spends at 49% Germany: taxes at 44% and spends at 45% Korea: taxes at 31% and spends at 30%
France is something of a world-leader when it comes to both taxing and spending, especially least among developed nations. The USA is a big world-leader when it comes to government living outside its means.
Previous posters have pointed out how the extreme volatility of bitcoins makes them unsuitable as a currency. I'll add that the risk of loss (due to technical problems with one's own equipment or to hacks at repositories) seems uncomfortably high too.
I might buy one if it would just make game and level loading faster for my existing library, and eliminate some other long pauses like for popup menus. Egad that thing is slow.
Every time I run man and get a pointer to texinfo, I want to beat my head on the keyboard. I do not have the time, once again, to look up those obscure keyboard commands so that I may navigate laboriously through the documentation. It's time to interrupt my command-line workflow, go to the nearest GUI and run a web search for the nearest HTML manual.
One thing I would like to see in these AI systems is occasional variations in their recommendations (for each given symptom set) for experimental purposes. It would be easy to code, and the results could be used to help choose the best outcomes. If two different treatments appear equivalent in outcome, the AIs should prescribe them randomly in a 50/50 ratio, modifying the ratio as new evidence arrives.

Swoosh...you just restated his point.
You would think MIT of all places would be able to put together a website capable of withstanding real traffic.

Mod parent up...the LoC did a great job -- more than anyone else around -- of pushing Congress in the direction of doing the right thing.

It won't be long now until these two are shooting at each other!

Could we please have more jargon and name-checks in the summary?

That's one of the nice things about OpenCL. I wish they would come up with more (and better) math libraries.

I won't comment on value, but rather just inject some harder numbers into this debate:
OECD National Accounts at a Glance, 2012
http://knoema.com/OECDNA2012
France taxes at a rate of (roughly) 51% of GDP and spends at 56%
The USA taxes at 32% and spends at 42% (2010 accounts)
UK: taxes at 40% and spends at 49%

Allow me to initiate the inevitable hatefest:
