Putting a MacBook Pro In the Oven To Fix It

mathfeel Re:Heat gun (304 comments)

Use a fucking heat gun. Don't back your shit. Jesus, what kind of fucking rookies live in this world?

From TFA, he did use a heat gun when it failed again. That did not work. Then he used the oven again and drill some holes for air flow. That worked.

I believe this is the group that pushed the defeated Prop 46 this year. This is a proposition that 1. increase the cap on malpractice sue from the current $250K to $1M and 2. required doctors and nurses undergo random drug test.

Mathematical Proof That the Universe Could Come From Nothing

mathfeel Re:Nothing? (429 comments)

there is always the question 'but what caused that'? really? there is "always" this question only if you continue to think about the world in the same mindset.

you don't have to search for an answer in the world through Newtonian glasses. "caused" implies causation. causation implies a before, and an after. first there is the cause, then there is its effects. abstract ideas like before and after are looking at the world from a point of view of LINEAR time.

if you truly study relativity

If you truly study relativity, you'll see the words "causality" and "causal" used. It's not a strictly Newtonian idea. As long as there's no faster-than-light travel, "X happens before Y" is an invariant - it's true in all reference frames.

Only if the two events are time-like separated. That is, there does not exist a frame in which they are simultaneous. If two event are space-like separated, there is one frame in which they are simultaneous. Then there is a frame in which A occurs before B and another frame in which B occurs before A. The two events cannot be causally connected.

If two events are time-like separated, (basically means their spacial separation / time separation is less than speed of light), then their order of occurrence is fixed in all frame. Because in this case, it is in principle possible for A to causally effect B since any signal emitted at event A can travel to B at no faster than the speed of light, the causal relationship between A and B is the same in all frame.

tl;dr If A can cause B in one frame, A can cause B in all frames.

The Bursting Social Media Advertising Bubble

mathfeel Re:Tuning it out? (254 comments)

I almost feel like I am forced to use AdBlock by bad ad. Before I install AdBlock, I said to myself, sure online ads are bad, but that's how the "free" world works. Then I noticed some website wold take forever to load, but once I clicked "STOP" on my browser, the content page showed up. I am forced to conclude that the content I want has already been loaded, but some part of the page is trying and failing to connect an ad server somewhere. I don't mind online ad, really. I tune them out. But if it starts to degrade my web browsing experience, AdBlock to the rescue.

Studies: Wildfires Worse Due To Global Warming

mathfeel Re:No, no it's not. (379 comments)

Thirdly, unless you've just moved to San Diego, you're quite aware of the 2003 and 2007 fires. These were (also) not the result of global warming.

I remember both of those cases well: classes are cancelled for a week, because they occurred during Fall semester in September/October. This one is in May. Having a longer fire season is exactly what the OP is stating.

Russian State TV Anchor: Russia Could Turn US To "Radioactive Ash"

China also won't join Russia because they don't want what Russian is proposing for Crimea, referendum for independent, become an international precedent for its many regions: Taiwan, Tibet, etc.

Why are we still in this Cold War mentality that the two formal communist countries are join at the hip. They have many diagonal interests, even during the Cold War.

Facebook To Buy WhatsApp

mathfeel Re:Messaging? (199 comments)

I use WhatsApp. Two reasons. One, the message seamlessly integrates with insert photos, audio, and video. Traditional SMS does not support those media well. Two, it is very popular out of the US. I have a lot of personal contacts from Taiwan, Hong Kong, and Europe. It is nice to have everyone on the same platform. I have no idea about how much international SMS costs.
Recently (last two years), I have noticed that most of the messaging activities between my contacts and I have be gradually shifting from Whatsapp to, ironically, Facebook messenger. I paid 3 years license a few years back. It looks like I will not be renewing.

South Carolina Education Committee Removes Evolution From Standards

mathfeel Re:Which Creation? (665 comments)

I have no problem with presenting creationism as an alternative, as long as you include ALL creation myths in the curriculum. It wouldn't be "teaching the controversy" unless you teach them all.

I mean, sure, we all really KNOW that the world began when Udu the Space Tortoise shat out the earth and His godly flatulence created the sun, but we have to let the kids decide for themselves.

I have no problem with what you are suggesting either. Just don't do it in a science classroom because none of these are science.

Geeks For Monarchy: The Rise of the Neoreactionaries

mathfeel Re:Buy these morons a history book (730 comments)

Please! Someone buy these idiots a history book. This is such a perfect example of people who think they're smart but they actually know jack shit about anything except pushing bits. The funny thing is, after the first arbitrary detention and execution of a dissident for "lesse majesty" or "treason against the crown" they'd all be up in arms and in jail. I really hope they're not all really this stupid and this is all just a way to get a reaction.

Just so happened that I read this today: http://en.wikipedia.org/wiki/Flexible_glass
These guys think they are smart. That if other smart people are put in charge, their ability (if they actually possesses it) would be recognized and rewarded. But if their innovation disturbs the power of elites that they are proposing to put on top, whom they think will grand them reward for innovation, they are reading history (if they have read history) wrong.

Seriously. If you imagine that you will come out on top when your competition in a job interview is a noticeably lesser-able, but probably competent, son of the CEO, you got to examine your understanding of human society.

The Man Who Convinced Us We Needed Vitamin Supplements

mathfeel Re:Peer review (707 comments)

In fact, because he is a member of the National Academy of Science, he could publish paper on PNAS (Proceeding of the NAS) without much peer review (or find sympathetic scientists to review his paper). In the old day, there was an honor system with respect to publishing in PNAS that the author should get their paper properly peer-reviewed. Pauling submitted a series of very shoddy vitamin studies to the PNAS and as a result, he single handedly changed this policy and now makes publishing to PNAS a lot more rigorous. http://scienceblogs.com/insolence/2009/02/18/vitamin-c-and-cancer-has-linus-pauling-b/

Charge Your Cellphone In 20 Seconds (Eventually)

mathfeel Intrigued... (295 comments)

But what did she do? What is the underlying science/technology? The NBC report got nothing. Click-through to Intel's website for the competition did not immediately yield any more information, except an inspirational paragraph about her:

With the rapid adoption of portable electronics, Eesha Khare, 18, of Saratoga, California, recognized the crucial need for energy-efficient storage devices. She developed a tiny device that fits inside cell phone batteries, allowing them to fully charge within 20-30 seconds. Eesha’s invention also has potential applications for car batteries.

Will be doing some more Googling, but seriously, a link to the lab in which she worked or article/abstract published would be nice. Surely these are gifted kids, but I can't help but think the reporter really doesn't understand what she's done to write any thing more than a press release.

N. Carolina May Ban Tesla Sales To Prevent "Unfair Competition"

mathfeel Re:And we don't need the man in the middle indeed. (555 comments)

It is not going to stop that. But the additional work required to do that means only enthusiast (like yourself, perhaps?) will go out of his/her own way to own one. Creating sufficient friction for entrance is often enough to protect established players from competition. It also gives politicians an excuse to say: I am not against your freedom to buy a Tesla, I am just for a little more freedom for our local, lovable, car dealerships. FREEDOM!

Never underestimate what people are willing to go through (on any device) to mask the cognitive dissonant that the latest precious they just bought does not justify its price or hype. The effort people go through to justify the sunk cost, both in economy and psychology.

Science Wins Over Creationism In South Korea

mathfeel Re:Neil DeGrasse quote instantly came to mind. (302 comments)

How so? The age of the universe was 13.7 billion years in 2006, now its 14.6 billion years old. According to science, the universe has aged 900 million years in just six years.

Details of your statement aside, you have inadvertently alighted on the fundamental difference between science and religion: when new evidence comes in, science is obligated to change their theories to account for it, whereas religion is obligated to deny the evidence in order to preserve their beliefs.

Even more to the point, there are multiple methods of measuring the age of the universe. Some more precise than other; Some more accurate than other. They are not in huge contradiction with each other, certainly no where near the ridiculus claims religion is making. http://astro.berkeley.edu/~dperley/univage/univage.html

People really needs to learn statistic and in addition to findings, reporter really need be able to report on the uncertainty of the findings.

Chinese Students Say They Are Being Forced To Build Your Next iPhone

mathfeel Re:It's an internship. (481 comments)

I failed to google up the university's site. Reading similar reports in Chinese, it seems that Huai'An university is probably closer to what we call a trade school in the state. Students attends very career oriented majors: accounting, education, law, management and there is no research faculty (I wouldn't be surprise if most of the teacher does not hold PhD degrees).

Apple Seeks To Block 8 Samsung Products After Court Win

Nothing like a forbidden/unavailable product that fires people up. In fact, a few of my friends are already discussing going to Oregan (no sale tax) to grab the new generation of iphone when it comes out and fly back to HK/China/TW with them to make enough profit to cover the said flight because Apple generally releases its phones later in Asia.

Apple to list companies that build its products an

mathfeel mathfeel writes  |  about 3 years ago

mathfeel (937008) writes "Indulge me in some post hoc reasoning here: After last week's episode of This American Life "Mr. Daisey and the Apple Factory", a very interesting show, Apple announced that "For the first time, Apple has released a list of companies that build its products around the world. In another first, the company also announced that it will allow an independent third party to check on working conditions at those factories, and to make its findings public." But before you celebrate Apple's gesture (or complain about the potential increase in electronic price): "It doesn’t appear that Apple’s partnership with the FLA will increase transparency in this regard either. The FLA will audit 5% of the factories that make Apple products, but like Apple, it will not name which ones it checks or where it finds violations.""

China now has the fastest supercomputer

mathfeel mathfeel writes  |  more than 4 years ago

mathfeel (937008) writes "NYT is reporting that China will take the top crown when Top 500 is released next month. Before one comments that the major components are still designed by US firms like Intel and Nvidia, FTA:

Modern supercomputers are built by combining thousands of small computer servers and using software to turn them into a single entity. In that sense, any organization with enough money and expertise can buy what amount to off-the-shelf components and create a fast machine. The Chinese system follows that model by linking thousands upon thousands of chips made by the American companies Intel and Nvidia. But the secret sauce behind the system--and the technological achievement--is the interconnect, or networking technology, developed by Chinese researchers that shuttles data back and forth across the smaller computers at breakneck rates, Mr. Dongarra said. "That technology was built by them," Mr. Dongarra said. "They are taking supercomputing very seriously and making a deep commitment."

The said interconnect designed by the Chinese are shown to be faster than the InfiniBand used in many supercomputer. In the current wave of shouting "Cut, Baby Cut" from the most vocal segment of the US's political class, will the PRC, with its endless ambition and recent acquired cash (when they are not busy loaning it to the US), catches up or even surpass the US in doing fundamental research that is the long term foundation of an economy?"

Study of homework copying in MIT

mathfeel mathfeel writes  |  more than 4 years ago

mathfeel (937008) writes "A statistical study by MIT professors of their calculus-based introductory physics courses (Journal version here: http://prst-per.aps.org/abstract/PRSTPER/v6/i1/e010104 for those who have access.) has a few interesting conclusions, not the least of which is "repetitive copiers have approximately three times the chance of failing":

Equating speedy answers with copying, the team concluded that about 10 percent of the students copied more than half of their homework, about 40 percent copied 10 to 50 percent of their homework, and about half the students copied less than 10 percent of their homework. By the end of the semester, students who copied 50 percent or more homework earned almost two letter grades below students who didn't copy very much, the team found. Heavy copiers were also three times more likely to fail the course.

They also report that certain change in course formatting and self-reporting academic dishonesty survey has reduced copying by factor of 4."
