Berkeley Lab Builds World Record Tabletop-Size Particle Accelerator

grimJester The LEP only went to 104,5 GeV (90 comments)

Electron-positron collisions are much cleaner than proton-proton ones. The LEP did exclude the Higgs up to 115 GeV while it actually was around 125, so scaling this up by a factor of 40 or so would make a small Higgs factory. Dunno about luminosity but maybe that's not a problem.

Samsung SSD 850 EVO 32-Layer 3D V-NAND-Based SSD Tested

grimJester Re:Very cool. (127 comments)

How much space do they need? If you're talking tens of GB, is that really more expensive than the smallest spinning disk drive you can get?

Mathematical Trick Helps Smash Record For the Largest Quantum Factorization

grimJester So worst case still classically exponential, but.. (62 comments)

If I understand correctly, the classical version of this factoring scales with 2^n where n is the number of bits different in the two binary factors. Wouldn't there be some kind of trick to handle situations where more than half the bits are different though? IIRC this still wouldn't be the best known classical algorithm, but this seems worth some thought.

Also nice to see the whys and wherefores of quantum algorithms being better understood, but can't really say I know enough so see if this gives any more general insights.

Hawking Warns Strong AI Could Threaten Humanity

grimJester Re:Is Already Happening (574 comments)

The time when humans are being replaced by robots is already here.

Amazon does it in warehouses, waiters are going away, manufacturing, you name it. The crux is there are a billion more people in the next ten years. There will not be enough jobs for these people. Yes, yes, we already know no one gives a damn about the bushmen in the middle of nowhere, but we are talking about Americans. This push towards a service sector economy looks great on paper but sucks in reality. Nations that are not makers are not nations for long. We are declining. Our children learn nothing in schools that will be applicable to them in a meaningful way. STEM is not taught in the US. We have common core, which is a joke designed to bring everyone down to the lowest common denominator. We either start making stuff again or we fade out. Where will everyone work in a service-based economy? Fast food? These jobs are being phased out slowly, but quickly enough.

The proportion of service sector jobs increased from maybe 5% to 50% between 1800 and 1950 and is around 70% now. Your claims could have made sense two centuries ago. Having manufacturing go from 20% to 5% of jobs changes nothing.

Rooftop Solar Could Reach Price Parity In the US By 2016

grimJester Tax credits end in 2016 (516 comments)

There's a 30% tax credit expiring in 2016. Not sure what you mean about an "idea" and being "scalable"; it's just a bank projecting in what areas photovoltaics will be worthwhile when. After 2016, you'll presumably still have new installations worthwhile in the south of the country and the area creeping northwards as prices continue going down.

You know they're desperate when the only argument against new technologies they can come up with is that they're ugly.

CERN May Not Have Discovered Higgs Boson After All

grimJester Higgs impostor (137 comments)

There are loads of Higgs impostor models where something else mimics the Higgs. Perhaps they're unlikely but it's not easy to come up with alternative explanations that are both mathematically consistent and don't contradict observations.

Physicists Resurrect an Old, Strange Dark Matter Theory

grimJester Just too few to see (138 comments)

Nothing like an invisibility cloak. If I understand the paper correctly they're just heavy enough that there are few enough that we haven't seen them.

Researchers At Brown University Shattered a Quantum Wave Function

grimJester Useful superposition amplifier? (150 comments)

This sounds like a way to detect many of the possible positions of a particle at the same time. Could this be useful for quantum computing?

Manga Images Depicting Children Lead to Conviction in UK

grimJester Grey area stuff, non-lolicon (475 comments)

I don't really like the arguments that a character drawn looking like a human child could be older according to the story, but I do think the opposite is a minefield. Loads of manga/cartoon porn features adult-looking characters that are underage in the original non-porn story and (I'd assume, lol) lots of people fap to these without knowing or caring that the original wasn't 18.

In addition there's a lot of hentai where many wouldn't think twice about the risk of someone being underage but looking more carefully at it one could make a fairly convincing argument someone is under 18.

A Swedish case had the entire court room laughing when the prosecutor claimed a manga character giving a blowjob was obviously underage because of the undeveloped boobs when it was actually gay porn.

I don't feel any attraction to underage women and have never to my knowledge seen actual child porn on the net (Samantha Fox's boobs and Scorpion's Virgin Killer album don't count) but fapping to completely normal manga could technically land me in jail. That's fucking scary. I'll have to fap to non-normal manga for now.

Too Much Privacy: Finnish Police Want Big Euro Notes Taken Out of Circulation

grimJester Casino winnings can be too large (314 comments)

Getting even 2k in 50s would be annoying. Alko can usually give change on a 500 if you need to break it. (Alko = state booze monopoly for the non-Finns)

I can't see how using hundreds would really inconvenience criminals either. A quick search says a million would weigh 2kg in 500s, meaning 10kg in 100s. Smuggling huge sums across national borders might become harder but otherwise, who cares.

NVIDIA Launches Maxwell-Based GeForce GTX 980 and GeForce GTX 970 GPUs

grimJester Samsung UE40HU6900 has HDMI 2.0, cheap enough (125 comments)

800 euro locally. A GTX 970 seems like overkill / waste of money for my purposes, so I guess I'll wait a month or two.

Thanks again for the help!

NVIDIA Launches Maxwell-Based GeForce GTX 980 and GeForce GTX 970 GPUs

grimJester Thanks (125 comments)

The newly launched Nvidia GTX 980 and 970 support HDMI 2.0 and DP, so these can run 4k@60hz with TV and monitors that support it, I think some Samsung and LG TVs advertise HDMI 2.0 and DP.

Ok, so it's a somewhat reasonable idea to get 60Hz on a TV without spending the cash for a 4k monitor.

here are a couple threads where I found most of the information before I bought it: http://www.overclock.net/t/144... http://hardforum.com/showthrea...

Thanks, I'll have a look at these.

NVIDIA Launches Maxwell-Based GeForce GTX 980 and GeForce GTX 970 GPUs

grimJester Looking for info on running 4k screens (125 comments)

I'm thinking about upgrading my monitor to 4k but I'm a bit confused about the current situation with both connectors and screens. How is running 4k@30Hz for normal desktop purposes, with no 3d gaming? Are the cheap 4k 39-40" TVs completely fine for those purposes? What connector(s) do I need from my GPU? How long would I have to wait for GPUs and TVs/monitors to support 4k@60Hz (HDMI 2.0? Displayport x.y?). Can I connect more than one screen to a single GPU card if I want 4k?

This might be a candidate for Ask Slashdot, I guess

Tesla Plans To Power Its Gigafactory With Renewables Alone

grimJester Might use batteries too (260 comments)

Obviously a battery factory will have some amount of batteries on site. The 2400 MWh/day figure from the article would be around 30 000 full Model S battery packs, so going completely off-grid using whatever batteries they have lying around is unfeasible. Anyway, no point in not using them, right?
