Where they have uniformly fallen short is in the amount of energy they can store as compared to a battery, and WRT the engineering backflips required to get higher voltages (which is the key to higher energy storage because the energy stored in a cap scales with the square of the cap's voltage, whereas doubling the cap's actual capacitance only doubles the energy, or in other words, the energy increase is linear.) This new development addresses these shortcomings all at once: considerably higher voltage, smaller size, higher capacitance, and to top it off, utilizes less corrosive internals. The best news of all: This new technology looks to be easy, even trivial, to manufacture, and uses inexpensive materials — and that is something neither batteries or previous types of ultracaps have been able to claim. After the debacle of EEStor's claims and failure to meet them for so long, and the somewhat related very slow advance of other ultracap technology, it's difficult not to be cynical. But if you read TFA (yes, I know, but perhaps you'll do it anyway) you may decide some optimism might actually be called for.

Well worth a read, and it is also worth following the various links in the post; they range from eye-opening to absolutely horrifying.

Keeping in mind that this is only what's been discovered so far, and given what's known to be going on, it's not unthinkable that more is as well. Should users just sit back and accept this as the new normal? It will be interesting to see if these discoveries result in an outcry, or not.
fyngyrz writes: RRAM, a long-awaited alternative to other memory technologies that can retain data while powered down, has finally reached manufacturing. With higher data density, 3D stacking on chip (not chip-on-chip, but layer-on layer), lower power, more longevity, RRAM seems poised to drive electronic storage considerably forward. If initial designs use the current interfaces, we could see some immediate performance gains (RRAM is quite a bit faster than flash) as well as increased data capacities. Of course, no one needs more than... oh, never mind.

Samsung, in offering the source code to these two cameras, may have tapped a golden vein. I'm a Canon user, but upon learning this, I immediately began to consider Samsung as a 2nd camera.

Turns out that Twitter has sold a huge database of several years tweets to a marketing company, which in turn has quite a list of customers ready to data-mine the trove of remarks about, well, everything."

Einstein showed that mass and energy are the same thing. The time machine we’ve designed uses light in the form of circulating lasers to warp or loop time.
In Einstein’s theory it turns out that not only matter such as the Earth can create gravity but also light. It is the energy of light that creates gravity. Consequently, since time is affected by gravity and light can create gravity due to its energy then light can also affect time."

The idea being to make all transactions traceable, thus foiling copper theft, etc. This move has profound implications that range from constitutional rights to bitcoin, Craigslist and so forth; I wonder if there are any slashdotters at all that support such a move."

fyngyrz writes: So you think of electrons like dominoes in a wire. Push on the one in the end, the others react one after another. Pretty vanilla physics. Further, because the electrons are moving, you get magnetic effects, radio, etc. Good stuff. So. What if you move all the "dominos" at once? Put your virtual hand on all of them, and push them over. They're not moving sequentially any longer. They move together. At any speed you can make them go. Well, that's what these researchers are doing — "pushing" all along a conductor at once, able to make a signal go — ready? — FTL. Fascinating stuff. And it may explain pulsars.

They're seeking an injunction against the game, which could do some real sales damage during the holiday season if granted.
Now, speaking as a musician, I'm right with the program when people say copyright is flawed, but... has this band fallen off the edge here?"

A study has been submitted for publication in the journal Energy and Environment which actually looks at the level of support in the scientific community. From the results: "Of 528 total papers on climate change, only 38 (7%) gave an explicit endorsement of the consensus. If one considers "implicit" endorsement (accepting the consensus without explicit statement), the figure rises to 45%. However, while only 32 papers (6%) reject the consensus outright, the largest category (48%) are neutral papers, refusing to either accept or reject the hypothesis." It is very interesting to see how neutral (and properly so!) the scientific community actually remains when it comes to anthropocentric global warming.
Are we seeing the pendulum swing back to a rational position?"
fyngyrz writes: "As always, there are rumbles of discontent from the scientific community with regard to global warming. This article from R. Timothy Patterson, professor and director of the Ottawa-Carleton Geoscience Centre, Department of Earth Sciences, Carleton University, lays the overriding mechanism of climate change squarely at the feet of the various solar cycles. In the article, he explains that solar energy impacting the earth is part of the mechanism, while the sun's solar wind drives cloud formation in a complementary cycle that enhances the effect of the actual heat input. But that's not the kicker. The interesting part is he is predicting global cooling, rather than warming."
fyngyrz writes: "Looks like Mars is warming just as fast as we are. Unfortunately, it's a little more difficult to whip the public into a frenzy of guilt over emissions when even the most daft rank and file citizen will figure out that our CO2 excess doesn't make it to Mars under any circumstances, and so the discovery doesn't bode well for the CO2 alarmists.
Looks like we might be back to terrorists, panicking over each others morals, and legislating personal choices for the entertainment of the day."
