Comment Slobodan Cuk is not convinced. (Score 1) 245

Slobodan Cuk of "Cuk's converter" fame ( is not very convinced. From the commentaries:

I could not find anywhere in a number of public announcements the efficiency achieved for any of the top three designs! It appears then that efficiency was NOT a criterion at all in Google's Little Box challenge, but only Power Density and resulting total volume!
I spent 42 years in Power Electronics with the main goal of improving efficiency and reducing magnetics size tenfold without increasing switching frequency! Both are the prime factors enabling smaller size and weight! Without the efficiency objective and novel systems solutions, the glorification of the power density alone sends absolutely wrong signals to Power Electronics industry and misleads young engineers as to what is really important! This is one man’s opinion, I invite yours!

Life span in 1798 was 103!

From wikipedia

The longest-living person whose dates of birth and death were verified to the modern norms of Guinness World Records and the Gerontology Research Group was Jeanne Calment, a French woman who lived to 122. The maximum (recorded) life span for humans has increased from 103 in 1798 to 110 years in 1898, 115 years in 1986, and 122.45 years since Calment's death in 1997 (See List of the verified oldest people and List of verified supercentenarians who died before 1980), among steady improvements in overall life expectancy. Reduction of infant mortality has accounted for most of this increased average longevity, but since the 1960s mortality rates among those over 80 years have decreased by about 1.5% per year. "The progress being made in lengthening lifespans and postponing senescence is entirely due to medical and public-health efforts, rising standards of living, better education, healthier nutrition and more salubrious lifestyles."[3]

The main improvement was in childbirth mortality thanks to sanitation and vaccines. Life span and life expectancy are not the same thing.

I would think that Jenner is an outliner,

What repulses conservatives is the fact of someone not being hetero normative. As I said before, a trans person is one who adopts (through a lot of work) a very defined hetero normative sexual identity.

If a gay person wants to be "cured" i.e. adopt an hetero normative identity he will be accepted and congratulated. I know, it is not the same, but the common thing here is being hetero normative.

Some trans persons could pass as a perfectly *normal* person, regarding their sexual behavior, in the eyes of other people.

Our pediatrician once told me, every kid should have eaten a pound of dirt by the time they're two. While she didn't mean it literally (at least not that much dirt), she's talked about the 'immune system needing exercise', and that helicopter parenting actually denies kids a certain amount of exposure that's healthy. To be clear she's NOT an anti-vaxxer, on the contrary, but thinks both natural and pharm assisted immunity/resistance is a good idea.

Probably she was thinking about the Hygiene Hipothesis

I can't tell if you're trying to be funny, or if you are actually as stupendously ignorant about science as you're post portrays you to be.... it's very hard to tell in writing. I generally try to give people the benefit of doubt, but i get the vibe you're not trying to be funny.

    Science is based on observation and experimentation. What that means is, the more exacting observations we make, and the more fine tuned our experimentation, the more precise our knowledge becomes... that's pretty basic, 4th-6th grade level science. If you want something that once said never, ever changes, regardless of new information, then stick to religion.

This is not science, is public health policy. One is supposed to be based in the other, but it is now always like that.

Submission + - GlaxoSmithKline "Accidentally" Released 45 Lts of Live Polio Virus (

ferespo writes: Belgium – As reported to ECDC by Belgian authorities, on 2 September 2014, following a human error, 45 litres of concentrated live polio virus solution were released into the environment by the pharmaceutical company, GlaxoSmithKline (GSK), in Rixensart city, Belgium. The liquid was conducted directly to a water-treatment plant (Rosieres) and released after treatment in river Lasne affluent of river Dyle which is affluent of the Escaut/Scheldt river. Belgium’s High Council of Public Health conducted a risk assessment that concluded that the risk of infection for the population exposed to the contaminated water is extremely low due to the high level of dilution and the high vaccination coverage (95%) in Belgium.

Submission + - Physisists observer the Majorana fermion for the first time (

Charliemopps writes: For the first time Princeton University scientists have observed a Majorana fermion. A long predicted but never observed exotic particle that acts as both matter and anti-matter. The material is surprisingly stable. Being in both states at once seems to make it act very weakly with its surrounding. This could also be a major step towards quantum computing.

Dr. Melik: This morning for breakfast he requested something called "wheat germ, organic honey and tiger's milk."

Dr. Aragon: [chuckling] Oh, yes. Those are the charmed substances that some years ago were thought to contain life-preserving properties.

Dr. Melik: You mean there was no deep fat? No steak or cream pies or ... hot fudge?

Dr. Aragon: Those were thought to be unhealthy ... precisely the opposite of what we now know to be true.

Dr. Melik: Incredible.

ferespo writes: Ian Glomski thought he was going to make a difference in the fight to protect people from deadly anthrax germs. He had done everything right — attended one top university, landed an assistant professorship at another.
But Glomski ran head-on into an unpleasant reality: These days, the scramble for money to conduct research has become stultifying.

So, he's giving up on science.

Comment "Liberty" is ideology, too (Score 1) 299

"Liberty", Individualism are all tenents of Libertarianism or simple Right wing ideology, so it is no surprise that Silicon Valley is against (or indiferent) to the Government or the State.

There is this idea, that there are choices that go beyond "left or right", choices that are not subjective but objective and universal.

Anytime that someone tells me that he has "no ideology" or "no political stance" I suspect he is a closeted right winger.

If you can live with less than perfect results (wasted space) you could apply pareto's principle, and start working with a list of file sizes in descending order and dedup manually until you recovered enough space. Chance are that 20% of files make up for 80% of space.
