The Raspberry Pi is not a development board, no matter how much its fanboys repeat that same false assertion.

A development board is marketed and sold to companies and engineers to facilitate their research and development of finished end products based on the architecture embodied in the development board.

In contrast, the RPi is being marketed, sold, and hyped to death, as a very low cost general purpose computer, based on a proprietary and IP-restricted Broadcom SOC, to be used by school children (and hobbyists) to learn basic programming and micro-controller principles. None of the customers buying the RPi will be using it to design other finished products based on the RPi architecture.

At this point, I wouldn't be surprised if the Raspberry Pi foundation's next excuse is that all of the boards are in Gregory Blepp's briefcase, and will be shipped out to customers just as soon as he returns from his vacation to never-never land.

Google Should Be Logging In To Facebook 95

Posted by Soulskill
from the playing-nice-with-the-other-loudmouth dept.
Frequent Slashdot contributor Bennett Haselton writes "Facebook indirectly accused Google of creating dummy accounts to log in and spider information from their site, and Google denied the charge. But if Google wants to help users discover what strangers can find out about them, then spidering Facebook with dummy accounts is exactly what they should be doing."

+ - IRS Nails CPA for Copying Steve Jobs, Google Execs 1

Submitted by theodp
theodp (442580) writes "Silly rabbit, $1 salaries are for super-wealthy tech execs! The WSJ reports that CPA David Watson incurred the wrath of the IRS by only paying himself $24,000 a year and declaring the rest of his take profit. It's a common tax-cutting maneuver that most computer consultants working through an S Corporation have probably considered. Unlike profit distributions, all salary is subject to a 2.9% Medicare tax and the first $106,800 is subject to a 12.4% Social Security tax (FICA). By reducing his salary, Watson didn't save any income taxes on the $379k in profit distributions he received in 2002 and 2003, but he did save nearly $20,000 in payroll taxes for the two years, the IRS argued, pegging Watson's true pay at $91,044 for each year. Judge Robert W. Pratt agreed that Watson's salary was too low, ruling that the CPA owed the extra tax plus interest and penalties. So why, you ask, don't members of the much-ballyhooed $1 Executive club like Steve Jobs, Larry Ellison, Sergey Brin, Larry Page, and Eric Schmidt get in hot water for their low-ball salaries? After all, how inequitable would it be if billionaires working full-time didn't have to kick in more than 15 cents into the Medicare and Social Security kitty? Sorry kids, the rich are different, and the New Global Elite have much better tax advisors than you!"

Edsj (1972476) writes "It seems Eric Schmidt didn't like the decision to deliver uncensored searches in China. It is reported the decision to withdraw censored searches in China was made by co-founder Larry Page sided with his founding partner, Sergey Brin and probably an internal battle for power begun. Schmidt also wasn't happy with the “don’t be evil” policy, something the Google founders were prepared to protect anytime. Schmidt lost some energy and focus after losing the China internal battle and decided to leave the position of CEO. It is also reported that the chairman position is a temporary one until he finds another business to take care."

+ - Obama: What's Good for GE is Good for the USA 1

Submitted by theodp
theodp (442580) writes "If you doubted that President Obama was going corporate, writes Joe Weisenthal, just look at who's been tapped to replace Paul Volcker as head of Obama's recovery panel. By naming General Electric CEO Jeffrey Immelt as his chief adviser on how to help U.S. companies create more jobs, Obama sent another signal that he wants to work more closely with big business. Joined by Immelt in Schenectady, a city once defined by GE, Obama toasted the creation of an estimated 350 jobs at the site of an under-construction GE battery plant, which was made possible with a reported $25.5 million Federal tax credit, $15 million in state funds, and wage concessions. Turning to Immelt to save the American worker is certainly outside of the box thinking. In 2004, Immelt boasted that 'Gecis [now Genpact] pioneered and set the standard' for offshore outsourcing as General Electric picked up a check for $500 million from VCs anxious to partner with GE in the lucrative global BPO business. Genpact has continued to lay golden eggs for GE — $100MM in 2007 and $300MM in 2010. And last tax season, even Forbes seemed aghast at how GE used overseas operations to pay nothing to Uncle Sam on $10.3 billion in pretax income. So it's no surprise that news of Immelt's appointment has drawn some skepticism. Still, in a 2009 speech, Immelt did do a turnabout of sorts, questioning the conventional wisdom of relying so heavily on off-shoring, which Immelt reiterated in his Washington Post Op-Ed on Friday. But whether Immelt will walk the talk remains to be seen. After all, less than a year ago, now-incorporated-in-Bermuda Genpact announced that GE has re-upped with its BPO creation through 2016, promising that 'Genpact will continue to have the first opportunity to provide new business process management services to GE.'"

Writing "3dB" is conceptually *exactly* the same as writing "200%".

I just checked the Wikipedia article, and it is totally correct, and agrees 100% with what I stated, as does every physics text that I've ever seen. The definition is what it is, and your assertion that "3dB" is exactly the same as "200%" is simply incorrect.

I don't want to repeat myself or belabor the point, but 3dB represents a 2:1 ratio of power, and a 1.41:1 ratio of voltage. This follows simply and irrefutably from the laws of physics at work, and the underlying mathematical relationship of the quantities being measured, be they field quantities or power quantities.

Remember the basic definitions of the quantities, which is that power is proportional to voltage^2, so it is mathematically impossible for them to change together by the same ratio.

When power changes 2:1, or expressed in dB, 10 * log(2) = 3dB,

Then voltage changes 1.41:1, or expressed in dB, 20 * log(1.41) = 3dB.

I hope that you can see now that your mistaken idea that "3dB==2:1 or 200%" for both voltage and power is impossible, because power is proportional to voltage^2, it is mathematically impossible for them to both vary by 2:1 at the same time.

(Just for posterity, a factor of 2 == 3dB *always*.)

That last point that you made for posterity is not correct, because the definition of dB relates to power ratios, and a 2:1 ratio of power is 3dB, whereas a 2:1 ratio of voltage results in a 4:1 ratio of power and 6dB of change.

So, a factor of 2 is only 3dB when measuring power, because for power dB is defined as: dB = 10 * log(P1/P0),

and 10 * log(2) = 3

But when measuring voltage, a factor of 2 is 6dB, because for voltage ratios, dB is defined as: dB = 20 * log(V1/V0),

and 20 * log(2) = 6

"I have several pieces of fruit, one of which is a banana grown in Ecuador."

It may well be that the second piece of fruit was also grown in Ecuador, just like the first one was, but I simply don't know, so I don't make any statement about its country of origin, nor do I ask you to make any assumption or draw any inference about its country of origin. Therefore, this statement isn't deliberately misleading, because I don't know the country of origin of the second piece of fruit, as it doesn't have a country of origin sticker on it. My statement is totally true and complete to the best of my knowledge, and does not deliberately withold any information.

The way I see it, the fact that I stated that the country of origin of the first piece of fruit is Ecuador does not imply or require that the second piece of fruit is or is not from Ecuador also.

The way I read and analyze the sentence is that it is conveying complete information about just one piece of fruit, and no information at all about the other piece of fruit. I don't think that it's correct to assume any facts or restrictions not explicitly stated.

Likewise, in the original problem, "I have two children, one of whom is a boy born on Tuesday. What is the probability that the other is also a boy?"

The parent may not know what day of the week their other child was born on, for many reasons, such as separation due to war from the pregnant mother before the child was born. The father may have escaped from the conflict with one child, and only know from witnesses that his pregnant wife was captured and gave birth to a child while in a prison camp. The child born in prison may have been born on a Tuesday too, but the father doesn't know, and doesn't say. So his statement is totally true and complete to the best of his knowledge. But we can't assume that his statement says anything at all about the day of birth of the second child, nor use it in our calculation of the probability that he or she is a boy.

You offer the analogy:

I have several pieces of fruit and one of them is a banana

But the statement in the puzzle is: "I have two children, one of whom is a boy born on a Tuesday

Your example sentence is not analagous to the original problem, because the original statement provides two facts about one of the children, whereas your sentence provides only one fact about one of the pieces of fruit, therefore your argument is flawed.

The correct analogy is: "I have several pieces of fruit, one of which is a banana grown in Ecuador."

It is obvious that this statement about one of the pieces of fruit does not make any statements about the nature of the other piece of fruit, and certainly does not preclude the possiblility that the second piece of fruit is also a banana. For example, the second piece of fruit could very easily be a banana grown in Honduras, and nobody would consider the statement about the first piece of fruit to be a lie.

+ - New Air Conditioner Process cuts energy use 50-90%-> 2

Submitted by necro81
necro81 (917438) writes "The U.S. National Renewable Energy Laboratory has announced that it has developed a new method for air conditioning that reduces energy use by 50-90%. The DEVap system cools air using evaporative cooling, which is not new, but combines the process with a liquid dessicant for pulling the water vapor out of the cooled air stream. The liquid dessicant, a very strong aqueous solution of lithium chloride or sodium chloride, is separated from the air stream by a permeable hydrophobic membrane. Heat is later used to evaporate water vapor back out — heat that can come from a variety of sources such as solar or natural gas. The dessicants are, compared to typical refrigerants like HCFCs, relatively safe for the environment."
