Interview with Linus Torvalds
From Mr. Open Source himself, personal history and motivations behind the Linux project and views of present trends.
Kevlar-lined school uniforms big in London
"Around 1 percent of crimes either have a knife used or intimated, so it is a tiny proportion of total crime," said Deputy Asst. Commissioner Al Hitchcock.Still, if it's your kid and the option is available, what're you going to do? There are orders from the U.S., but not for the school uniforms.
Safe bedside table
Well, it's an artsy-looking table in the first place, but the cool function compensates.
The pallidum as gateway to subconscious drives, possibly relevant to Parkinson's, addiction
I haven't even heard of this brain part (of the basal ganglia) known as the pallidum, but it seems to light up even with subliminal flashes. This whole subconscious access thing has some implications in addiction treatment as well as willful control in Parkinson's.
Severely affected patients who can hardly walk across the room have been known to walk briskly outdoors in response to a fire alarm. Walking may require both a conscious drive and a subconscious motivation that is amiss in Parkinson's, perhaps because of abnormalities in the pallidum and its associated neural circuitry.
Neglected growth miracles
I'm linking to the post which links to the actual paper so that you can peruse the comments. Income and life expectancy aren't necessarily associated it seems.
Between 1962 and 2002, life expectancy in the Middle East and North Africa...increased from around 48 years to 69 years...it was...the strongest performance of any region in the world...
...China, which saw life expectancy growing at 1.6 percent in the 1960s, collapsing to around 0.2 percent in the 1980s and 1990s, while income growth was going in the other direction.
"Did you know that The Gambia, Yemen, Bangladesh, Nepal, and Libya were all in the top ten gainers in life expectancy, 1962-2002?"
Criticker -- rating films, finding somebody with same tastes

Utopian communities that bombed
Mismanagement or unrealistic application of philosophy led to ruin. The Shakers are here, although they evidently still have one community left.
Watercone -- simple, solar way to get freshwater from saltwater
Wide, UV-resistant plastic cone's inside surface condenses water vapor from saltwater and lets it drip down to the lipped rim. Estimated at 1L of water per day. Overturn it to pour out.
Neutralizing amyloid-beta in blood removes it in Alzheimer's brain
If we are able to lower the levels of amyloid-beta circulating in blood by sequestering more of it there, then the brain should follow and lower its levels too. This is exactly what we found.
Comcast making bitTorrent seeding impossible; Cogeco, Rogers doing something similar
A few seconds after you connect to someone in the swarm the Sandvine application sends a peer reset message (RST flag) and the upload immediately stops. Most vulnerable are users in a relatively small swarm where you only have a couple of peers you can upload the file to. Only seeding seems to be prevented...But without seeding, I think trackers tag your crap ratio somehow and you get hit in some fashion; just get booted for the private ones, I guess. Cable provider Cogeco and Rogers are doing something similar on a smaller scale.
More ways to get around traffic shaping in general here.
Modern IQ ranges for various occupations
I don't know how to interpret stats data, but I'm going to guess that the four chunks are standard deviations. In that case, a given whole bar is 95% of the profession, so we're missing the extremes. For some reason, farm laborers skew up hard, holding their own at the top end against clerical, police and foremen.

Using light to flip on a neuron
Where electrode stimulation is very shotgun, this can activate a specific type of neuron. It comes down to neurons genetically manipulated to have photosensitive molecules attached to channel proteins on one end with the appropriate transmitter on the other end. Hit it with light and the the transmitter locks into place. Can better map functional pathways.

To grasp physics, students need to know about knowledge
Past physics grades didn't matter,
Those students... who recognised that knowledge is changing and constantly reorganised, were significantly more likely to show an understanding of Newton's laws of motion...However,
... sophisticated epistemological beliefs were necessary but not sufficient for a deep understanding of Newton's laws.Curriculum needs to be adjusted accordingly.

Freewebs redesign incorporates more Web 2.0
For site creation, but now incorporating more widget, YouTube, Digg, Photobucket options, even blog import.
This is your brain on love
Stuff we know about the brain when falling in love. Many mental illness parallels. Not only hard neuro, here's an interesting study:
About halfway across the [Capilano] bridge [5' wide, 230' above rocks and shallow rapids], each man ran into an attractive young woman claiming to be doing research on beautiful places. She asked him a few questions and gave him her phone number in case he had follow-up questions.
The experiment was repeated upriver on a bridge that was wide and sturdy and only 10 feet above a small rivulet. The same attractive coed met the men, brandishing the same questionnaire.
The result? Men crossing the scary bridge rated the woman on the Capilano bridge more attractive. And about half the men who met her called her afterward. Only two of 16 men on the stable bridge called.

Fishing rod pen
Extends to 37" long, capacity for 120 yd on 5 lb line -- enough for catching up to 4 lbs.
Paper-thin, flexible, biodegradable battery
... a new material that eliminates the need for a multilayer battery. They grew carbon nanotubes on a silicon substrate and impregnated the gaps between the tubes with cellulose—that's right, plain old paper ... By putting two sheets of paper together with the cellulose side facing inwards [tubules sticking out as electrodes] (and a drop of electrolyte on the paper), a supercapacitor is formed. These supercapacitors retain the flexibility of normal paper, but they have a rating that is comparable to that of standard commercial hardware—a 100g sheet could replace a 1300mAh battery.
To attract a mate, women display kindness
They primed with photographs of attractive people of the opposite sex and asked questions with only a couple of alternatives. In the end, primed women felt more inclined to perform conspicuous volunteer work.

Death penalty even though he didn't commit murder
The defendant Kenneth Foster was driving a car with three passengers in it. One of them, Mauriceo Brown, left the car and got into an altercation with Michael LaHood and ended up shooting him dead. Brown has been executed. In Texas, they can apply the law of parties to capital cases (the only state to do so) -- being an accomplice makes one the same as the principal. Brown claimed to the end that it wasn't planned and there seems to be evidence unheard at trial to support this assertion.
Ants' good manners prevent congestion
It's tough for humans to think of the collective in a moment of danger, but perhaps better behavior can be engineered, as in the evacuation from a building:
Perversely, if you simply put a pillar in front of the doorway you increase the evacuation speed.

Maybe you want to sign up for a site which requires that you provide an e-mail address to send a validation e-mail to. And maybe you don't want to give up your real e-mail address and end up on a bunch of spam lists.
The Wall Street Journal on how credit got so easy
A little recent history of monetary policy and capital flows from the WSJ to explain why so much bleeding is going on (like the 30% hit of that Goldman Sachs global equity fund ... in one week). One reaction leads to another unforeseen reaction.

Derren Brown takes someone's wallet by asking
From psychotherapist Milton H. Erickson's handshake induction:
Confusion is the basis of Erickson’s famous hypnotic handshake. Many actions are learned and operate as a single “chunk” of behavior: shaking hands and tying shoelaces being two classic examples. If the behavior is diverted or frozen midway, the person literally has no mental space for this - he is stopped in the middle of unconsciously executing a behavior that hasn’t got a “middle”. The mind responds by suspending itself in trance until either something happens to give a new direction, or it “snaps out”. A skilled hypnotist can often use that momentary confusion and suspension of normal processes to induce trance quickly and easily.
Women's guide to looking good in the 17th century
The Cosmo magazine of its day. Yearning to be rail thin was a problem back then too:
Bodies that are very Lean and Scragged, we must own, cannot be very Comely: It is a contrary Extream to Corpulency and the Parties Face always seems to carry Lent in it.What's wrong with Lent? A bit of sacrifice to reflect upon transcendence never hurt anybody. Just goes to show what comes from the land ruled by a materialist ethos.
