"NiTiNOL 60, or 60 NiTiNOL, is a Nickel Titanium alloy (nominally Ni-40wt% Ti) discovered in the late 1950s by the U. S. Naval Ordnance Laboratory (hence the "NOL" portion of the name NiTiNOL). Depending upon the heat treat history, 60 NiTiNOL has the ability to exhibit either superelastic properties in the hardened state or shape memory characteristics in the softened state."

Reportedly we are going to run out as early as 2020, definitely before 2030.

A bit of a downer, but interesting to think about.
Breaking bad news gently.
"Save the rain forests" has (for most first-world residents not presently part of #OccupyRainForest) a concerned-but-distant feel about it. It raises consciousness without doing too much to cause mental anguish.
Spend some time thinking about how things can fail (not uncommon for tech types, particularly on the ops side), and you start realizing there are a large number of paths to that destination. Some more probable than others.
For complex systems in general, the problem isn't the stuff you've got lots of -- yes, you can fit the human population into the state of Texas with a reasonable amount of breathing space (about 1025 ft^2 -- 32 feet square) -- but what constrains you -- Leibig's Law of the Minimum:

Turns out there are a lot of things humans (and civilization) depend on which are in fairly short order: energy, environmental sink capacity, topsoil, phosphorus, freshwater, and a whole slew of critical industrial minerals for starters.
And it's kind of a downer to think about it.
But ignoring problems doesn't make them go away.
How close is the tipping point? Good question.
I've been playing with some geometric grown and consumption calculations:

Turns out that if you take the numbers for oil consumption from BP's Annual Review for 2013 and plug them in, oil at present reserves, rates of growth, and consumption, runs out cold in 2048. What that actually means is that the rate of delivery is going to start getting choked much sooner, and it's peaked as of 2005 with a bit of a bumpy plateau since. Oil fuels 95% of all transporation, which in Richard Heinberg's eloquent turn of phrase is the heart of commerce.
I could go on about oil exploration capex (Steve Kopits), fracking well depletion rates, and a slew of other stuff, but you probably don't want to hear about it.

Can you imagine having an apple sprayed with anything more deadly?
Well, we moved onto DDT...
Sadly my 'Wikipedia' history was mostly littered with things I had looked up as a result of something posted on HN. The only other stand out entry was the page regarding 'G G Allin' - definitely interesting but totally not HN!!!
I did not know that.
Huh, apparently this plant generates 1/5 of the power of Sweden. I wonder what happens when such an important plant gets shut down temporarily? What would happen to the power infrastructure of the country if this plant melted down, is there some sort of redundancy? I know nothing about Sweden's electricity infrastructure, but would love to read more about it. Anybody got any links or knowledge?
I think this sort of post is perfect for HN. I hope the special:random page becomes a weekly occurrence and promotes a lot of wonderful discussion.
Instructions unclear: post the link to comments or as a new link?
"Davide Cesare, also known as Dax (1977 - March 16, 2003) was an Italian anti-fascist activist from Rozzano (Milano), who was stabbed to death by two far-right activists in Milan, the night of March 16, 2003. Cesare was brought to the hospital but died in the ambulance. Immediately after his death, members of his group tried to enter the hospital but were blocked by the police. This resulted in new riots with several people being injured, damage to police cars, and the emergency department suspending all activities for the whole night."

No, not as interesting as the "Quantum" may lead you to think...
"Quantum Care Limited is a company based in Welwyn Garden City, England, that runs both residential and nursing care homes (see residential care home and nursing care home). The company's head office is 4 Silver Court, Watchmead, Welwyn Garden City, Hertfordshire, England AL7 1TS. Quantum Care runs twenty-eight care homes, all but two in Hertfordshire."

I got both the smallest Wikipedia page I've ever seen, and the one with worst "words I understand" to "words that make me go 'huh?'" ratio I've come across.
The only US company to still make gum using chicle is http://www.gleegum.com/, most now use a cheaper synthetic rubber substitute.
Only interesting in how uninteresting it is. Only one true sentence on the page.
"Specific leaf area is defined as the ratio of leaf area to dry mass."
Interesting part is me being from Bosnia & Herzegovina...
