Comment Re:From TFA: bit-exact or not? (Score 1) 89

There used to be a web page called "Your Eyes Suck at Blue". You might find it on the Wayback machine.

You can tell the luminance of each individual channel more precisely than you can perceive differences in mixed color. This is due to the difference between rod and cone cells. Your perception of the color gamut is, sorry, imprecise. I'm sure that you really can't discriminate 256 bits of blue in the presence of other, varying, colors.

Rather than abuse every commenter who has not joined your specialty on Slashdot, please take the source and write about what you find.

Given that CPU and memory get less expensive over time, it is no surprise that algorithms work practically today that would not have when various standards groups started meeting. Ultimately, someone like you can state what the trade-offs are in clear English, and indeed whether they work at all, which is more productive than trading naah-naahs.

Except "being necessary ... militia ..." is not an operative clause, it is a prefatory clause. The operative clause is "the right of the people ... shall not be infringed."

Prefatory clauses are used to give some reasoning or approach, but not a binding condition.

You could rearrange the second amendment in today's parlance as such:

"The Right of the People to keep and bear arms shall not be infringed for reasons including, but not limited to, that a functioning and ready militia is necessary to the security of a free state."

Comment An ANTI-SCIENCE attack paid for by Koch brothers! (Score 1, Troll) 234

A new study trying to replicate results reported in allegedly high quality journals failed to do so in over 50% of cases.

I denounce this propaganda attack piece paid for by Koch brothers seeking to destroy the planet and drown the poor for profit!!!!

Oh, this is not about Climate science? Never mind...

And what do you actually know about psychological research?

I fail to see, what meglon's knowledge of psychological research has to do with his argument. Which is that psychologists — by the very nature of their chosen domain — aren't particularly good at conducting experiments. He may be wrong, or he may be right, but his own proficiency in psychology has little to no connection to the argument. One does not need to have ever touched the oddly-shaped ball to see, that the quarterback sucks.

I am also a fan of the "hard" sciences

Yeah, and I am a fan of synchronized swimming... But I don't pretend to be any good at it.

I can tell you that experiments in the social sciences (when done correctly) are far more controlled (relatively speaking)

It would seem, that the very point of TFA is that the "when done correctly" part is true a lot less often, than the taxpayers financing most of these had the right to believe...

With humans, animals, and other living things, the noise factor is intense.

Yes, of course. Your work is harder in that respect. But this does not mean, your profession is any better at it... You may have collectively lowered the bar for each other — either because of these difficulties or because of some inherent imprecision of your domain and/or sloppiness of its practitioners — and TFA reflects the sorry outcome...

We have had to develop highly sophisticated techniques to be able to perform science and uncover truth.

Once again, TFA suggests, that over half of what you are portraying to be the "uncovered truth" is not... And meglon thinks, that's because you are untrained for (and perhaps even uninterested in) proper experimentation.

Describing your profession's challenges does not refute his accusation, nor does a claim of being "a fan" of physics.

Comment Re:John Sculley? The guy who nearly killed Apple? (Score 2) 122

Scully increased Apple's revenue ten fold during his tenure as CEO. It was the idiots who followed him that tanked the company.

No, Scully allowed Apple to become unmanageable, Spindler nearly died trying to get a lid on it, and then Amelio made the decision that saved the company from oblivion, by picking NeXT over Be.

Chinese factories, who just were not accustomed to having this quality of finish, all of these little details that make a beautiful design

Have they tried some other country's factories? Like, to pick at random, the US? Just a thought...

How much more expensive would it make each unit, if they were made in a better place?

Not a quadcopter that took 30 minutes to get to the scene, setup and send to the target.

Drones are both cheaper and faster-moving than human police. Of course, having a cop on every corner would do more to suppress crime, but that's way too expensive a proposition. Omni-present cameras and drones are the economical compromise...

Comment Re:Risk Tolerance not that High (Score 1) 95

I live in the Netherlands, and while some of the things you describe happen here too, education is improving here. Not because of improved teaching methods, although there have been some innovations like interactive schoolboards and the use of the internet for finding information, but mostly because we set minimal levels of the skills teachers need to have. And still there is always a call for better, faster and radically different education. But nobody ever seems to care about why this is necessary and what good education is. Also, new methods that are tried out are not eveluated and our governments don't have long-term visions about education. Our current gouvernment doesn't have any vision about any subject, and therefore reacts to any stimulans (like accidents, disasters but also good things) with unnecessary new laws. What our education system needs most at the moment is a government that does nothing about it.
