Inside BitFury's 20 Megawatt Bitcoin Mine

afxgrin Re:20 megawatts (195 comments)

When the mining difficulty was low generating an appreciated $4000 worth of bitcoin cost a trivial amount of electricity. However, transaction processing than mining. Bitfury is just trying to squeeze the last little bit of lottery bitcoins from the mining algorithm. Comparing environmental impact on generating $4k of bitcoins vs mining gold is ridiculous, they don't compare at all.

The power consumption by modern banks processing fiat currency transactions (mostly imaginary money) compared to bitcoin transaction processing is a better comparison, and even then Bitfury won't last much longer as the mining difficulty will result in diminishing returns. The overall transaction processing will become far leaner when the payout is purely on the transaction fees.

World Health Organization Calls For Decriminalization of Drug Use

afxgrin Re:Finally! (474 comments)

" If you want to understand what removing legalization would result in, I recommend that you read "Diary of a Drug Fiend" by Aliestar Crowley."

You could also experiment with drugs yourself. Why read someone's opinion when you could just go and form your own.

Personally the injection route always made me a bit uneasy. It's probably the cleanest way to use these substances however, except for the poking a vein repeatedly part. All you need to do is form some sort of embolism by injecting regularly and you risk dying not even from the drug itself.

$500k "Energy-Harvesting" Kickstarter Scam Unfolding Right Now

afxgrin Re:There's also the price... (448 comments)

Broadband rectifying antennas aren't anything new really, sure the background RF from towers, other sources is quite significant, and most experts would point out that you can't power a bluetooth chipset on a few microwatts of harvested power - but you could use it to charge a capacitor and periodically power the chipset. An update every 30 seconds instead of continuous monitoring of an item still works for me. The only problem with making the tag so small is you don't have much space to make an antenna for longer wavelengths.

Fusion Power By 2020? Researchers Say Yes and Turn To Crowdfunding.

afxgrin Re:Bad move (280 comments)

The reaction itself does, my bad. Compared to a D-T reaction however it yields many photons. This isn't really my field of physics however, so it's whatever i picked up off wikipedia.

Fusion Power By 2020? Researchers Say Yes and Turn To Crowdfunding.

afxgrin Re:Bad move (280 comments)

Well this Mike Hopkins guy is mostly comparing neutron yields from the D-T reaction LPP were testing with. Lerner inevitably wants to use the p-B reaction which produces no neutrons (aside from residual gas sources), however to test his pinch device using D-T is much easier as the fusion temperature is lower. It also makes for a good comparison to other pinch devices. Since the p-B reaction yields mostly photons they seek to make a fusion device from the charged particles (a stream of electrons and ions) and the photon energy collected via photoelectric current. Some of those gammas are uncapturable but the energy still captured is supposedly a net gain once they can get a high enough plasma temperature.

Engineering the Photon Capture Sphere Thing (PCST) to capture photons and electrons while not activating all the material with a 100-year half-life used in its construction, nor having it rip itself apart from dissimilar metals and thermal gradients, not having an unacceptably high rate of particles sputter the crap out of inside, is all non-trivial and would require significant trial-and-error builds. This is of course assuming they manage to make a working p-B reaction with their pinch. Best of luck to Lerner, but I'm not counting on seeing any significant results unless some billionaire type takes a risk on him.

Some criticism of Mr. Lerner's DPF fusion approach by a person who seems to know what they're talking about. http://mikebhopkins.wordpress....

It really does look like he's just rebuilt a standard pinch device.

Google Tries To Defuse Glass "Myths"

afxgrin Re:A lense cover (363 comments)

Google Glass as an assistive device for the legally blind would fit a similar role. Especially with facial recognition enabled and audio feedback to the wearer, and just disable the display or make it a big block of colour output for people who are still 'blind' but can see a bit of light.

I imagine they would need two so they could obtain enough spatial information to aide in navigation.

However, I would feel bad for the legally blind to be assaulted for wearing Google Glass.

Russian Civil Law Changed By Wikimedia

afxgrin Re:Well done, Vladimir! (88 comments)

Still incomparable:

a) Kosovo doesn't share a border with the United States

b) Crimea had an ethnic cleansing attempt by the Russians - you can't argue that Kosovo had all sorts of Americans move to Kosovo to make a majority American population so they can vote to be annexed by America....

c) Kosovo is recognized by 108 UN member states. Crimea ... I think only by Russia so far.

d) Kosovo, another "autonomous region" was part of a country that was falling apart. Funny how Milosevic revoked Kosovo's autonomous status triggering the breakup of Yugoslavia to further his "Greater Serbia" agenda.

e) If you want to compare Puerto Rico, I guess lets go back to the 19th century and compare things:
The Imperial census of Crimea in 1897 found that the population of the governorate consisted of 1,447,790, with 762,804 male and 684,986 female.
Language Number Percentage (%)
Ukrainian (Little Russian) 611,121 42.21
Russian (Great Russian) 404,463 27.94
Belarusian (White Russian) 9,726 0.67

By this standard Crimea belongs to Ukraine.

It is grossly undemocratic and unethical to hold a referendum in Crimea when:

1) the Parliament of the so called "autonomous region of Crimea" was raided by Russian paramilitaries

2) the federal government which the "autonomous region of Crimea" lies within: Ukraine, is under civil strife and is holding elections in a few months.

3) Russia itself conducts massive military exercises near the border, in addition to holding a port they lease from the Ukrainian government while having their own forces step off the base and surround Ukrainian military bases.

For the above reasons no one at the UN should recognize Russia's annexation of Crimea, and no referendum result should be observed until Ukrainian federal elections are held under international supervision until international observers agree on the election result. All of this is bullshit otherwise.

"Russian self defence forces" - what a fucking joke.

Quebec Language Police Target Store Owner's Facebook Page

afxgrin Re: And in other news... (506 comments)

Funny how the Chinese immigrants in Quebec prefer to learn English over French - supposedly the reason PQ supporters want provincial level immigration controls. Don't make this into an Anglophone's not wanting to learn another language thing - it clearly extends beyond English speakers. Tabernac!
