Proposed Penalty For UK Hackers Who "Damage National Security": Life

doug141 Seriously (164 comments)

Eric Holder gave a televised interview in which he credited a whistle blower at a bank for allowing the bank executives to be held to account for their part in making money off liar's loans. The reporter missed the obvious follow-up question to Holder, "So whistleblowers are good?"

Counter point: Star Trek needed a universe in which they could tell not just one dystopian story, but a new one every week, by visiting a planet that went off the rails in one of the same ways we might.

Patents That Kill

doug141 Argument doesn't seem to make sense (240 comments)

If some inventors will "rest," then it's the promise of money that made them invent and patent in the first place. If you take away the patent, and therefore the promise of money, you won't even get the first invention out of the money-motivated. Especially if the patent-free economy is dominated with idea-stealing industrialists. Those motivated by other-than-money will keep inventing, patents or not.

Privacy Worries For 'Smart' Smoke Alarms

doug141 privacy and future presidential elections (90 comments)

I wonder what the first presidential election will be like when candidates are from the facebook generation. Companies like google, facebook, maybe snapchat will have dirt on all the candidates. Google alone will have every search the candidates ever did. Viable candidates will be only those people who are uncommonly boring, or influential enough to squelch the dirt, or trade it for favors. Imagine the power google wields... in part because they gave away their operation system, which doubles as an information vacuum.

That article at slate did not address the possibility of the universe being such an isolated system. It seemed to be an angry rant by a physicist who was mad at other scientists for not sharing his views on the material world and consciousness.

Happy 95th Anniversary, Relativity

doug141 Re:95 years but (120 comments)

My impression of the thought experiment was that it was actually asking the listener to consider questions like "if the universe is isolated, are we in superposition right now?" and "what is the relationship between consciousness and superposition?" At any rate, it has been fascinating to watch the moderation of your "simple resolution" post bounce between extremes.

Candidate for FCC Chair supports universal access to high speed internet

doug141 doug141 writes  |  about a year and a half ago

doug141 (863552) writes "Susan Crawford, law school professor and author of Captive Audience: The Telecom Industry and Monopoly in the New Guilded Age, says “Truly high-speed wired Internet access is as basic to innovation, economic growth, social communication, and the country’s competitiveness as electricity was a century ago,” Crawford writes, “but a limited number of Americans have access to it, many can’t afford it, and the country has handed control of it over to Comcast and a few other companies.”

In a recent TV interview, she pointed out high speed access in Hong Kong costs a fraction of what it does in New York city, because the US providers don't enter each other's markets. She wants to change that.

There's a petition to appoint Susan as FCC Chairman."

Federal judge says no right to secret ballot

doug141 (863552) writes "A Colorado county put bar codes on printed ballots in a last minute effort to comply with a rule about eliminating identifying markings. Citizens sued, because the bar codes can still be traced back to individual voters. In a surprise ruling, Denver U.S. District Judge Christine Arguello said the U.S. Constitution did not contain a "fundamental right" to secret ballots, the citizens could not show their voting rights had been violated, nor that they might suffer any specific injury from the bar codes."

Cheap breakthrough doubles solar cell output

doug141 (863552) writes "In standard solar cells, much energy is lost (as heat) from photons mismatched to the capability of silicon to capture them. A new technique uses a pentacene layer to down-convert each hot (un-captureable) electron to two electrons that can be captured by standard silicon cells."

study: data analysis poor in neuroscience journals

doug141 doug141 writes  |  more than 3 years ago

doug141 (863552) writes "Analyzing for a difference is easy. But analyzing a difference of a differences is done incorrectly half the time in studies published in neuroscience journals.
Nieuwenhuis looked at 513 papers published in five prestigious neuroscience journals over two years. In half the 157 studies where this error could have been made, it was. They broadened their search to 120 cellular and molecular articles in Nature Neuroscience, during 2009 and 2010: they found 25 studies committing this fallacy, and not one single paper analysed differences in effect sizes correctly."

Commercial personal jetpak for $86,000.

doug141 doug141 writes  |  more than 4 years ago

doug141 (863552) writes "The Jetpack is constructed from carbon fiber composite, has a dry weight of 250 lbs (excluding safety equipment) and measures 5 ft high x 5.5 ft wide x 5 ft long. It's driven by a 2.0 L V4 2 stroke engine rated at 200 hp (150 kw), can reach 8000 ft (estimated) and each of the two 1.7 ft wide rotors is made from carbon / Kevlar composite. At $86,000 it is pitched at the level of a high-end car. As sales and production volume increase they expect this to drop to the price of a mid-range car. A 10% deposit buys you a production slot for 12 months hence; progress payments are made during manufacture with final payment due on delivery."

SuperFreakonomics heralds cheap environment fixes

doug141 doug141 writes  |  more than 4 years ago

doug141 (863552) writes "The new book Superfreakenomics (Levitt & Dubner) discusses two geoengineering concepts from Intellectual Ventures that are incredibly cheap compared to their impact:

The first system, still under computer testing, uses simple buoys, placed in the seasonally warm ocean waters that breed hurricanes, powered by wave action, to slowly pump the warm water down about 100 feet to the much colder water. The resulting very-slightly cooler surface water would reduce the intensity of hurricanes (eliminating them is equally possible, but not desired). At $1 billion the system would cost far less than the damage caused by a single hurricane season.

The second system offers to cool the planet for only $250 million. The world output of sulfur dioxide (volcanoes, humans, sea spray, other sources) is 200 million tons, but it's all in the troposphere. In 1991, the heavily studied Mt. Pinatubo eruption sent some sulfur dioxide into the stratosphere and cooled the world. Modeling shows a mere 100,000 tons per year of SO2, which is a garden-hose-like 34 gallons per minute, and one twentieth of one percent of the world troposphere emissions, would reverse arctic warming and reduce northern hemisphere warming. If the system is shut off the stratosphere would return to normal in a couple of years, just as it did after the Pinatubo eruption, so the whatcouldpossiblygowrong argument is weak. Several delivery systems could work such as a long chain of hoses, pumps and balloons, or a tall lightweight chimney held by weather balloons.

The book also brings to light two interesting facts about global warming:

1) Eating locally grown food over mass produced food actually increases greenhouse emissions, because only 11 percent of of food emissions are transportation related (and delivery from producer to retailer is only 4%). A full 80% of food related emissions are from production, and big farms are far more efficient than small farms.

2) The world's cows, sheep and other cud-chewers are responsible for 50% more greenhouse gas than the entire transportation sector, due to methane being 25 times more potent than CO2. Forgoing beef for one day a week is better than switching to a hybrid vehicle."

Asteroid 1:1400 chance of Earthstrike in 160 years

doug141 doug141 writes  |  more than 5 years ago

doug141 (863552) writes "Asteroid 1999 RQ36, that had initially been deemed harmless, has turned out to have a 1 in 1400 chance of hitting Earth in 160 years. There's far less time available to deflect it off course, with the window between 2060 and 2080. With an estimated diameter of 560 meters, 1999 RQ36 is more than twice the size of the better-known asteroid Apophis. Both are large enough to unleash devastating tsunamis if they were to smash into the ocean."

Video game conditioning spills over into real life

doug141 doug141 writes  |  more than 5 years ago

doug141 (863552) writes "Lessons learned in video games may transcend computers, PlayStations and Wiis. New research suggests that virtual worlds sway real-life choices. Twenty-two volunteers who played a cycling game learned to associate one team's jersey with a good flavored drink and another team's jersey with a bad flavored drink. Days later, 3/4 of the subjects avoided the same jersey in a real-world test. Marketers and lawyers will take note."
