We have a 2200% increase in the number of people living to age 100, compared to a doubling of the overall population (US figures, with 53000 centenarians).
As recently as 1995, for instance, a man with advanced coronary disease was flatly uninsurable. Now it's expected that an arterial blockage can be repaired relatively simply and new plaque buildups can often be controlled with medication, so that life expectancy is only modestly affected.

Lisa Harouni: A primer on 3D printing
Lisa Harouni
Looks like she works for a company in the 3d printing business.
We've had 3d printing for 30 years. Is this the year of its breakthrough?
Think Kinkos, but with a 3d printer.
You can print in metal (steel, titanium, ...) or plastic or imitation sandstone or ..., items up to 3 meters tall.
Printing allows for intricacies of design beyond what even the most skilled artesian can achieve by hand.
Mass customization. She claims it is profitable for runs of 1, you don't need big production and there is no economy of scale.
What about printing replacement parts for old items? Why not?
What about if these items are biological-- 3d printing with cells to create new organs. It works in the lab.
You can also print medical grade metals with honeycomb structure, which the body prefers for implants.
Replacement teeth printed for you at the dentist, while you wait.

Peter van Uhm: Why I chose a gun
Peter van Uhm, head of the Dutch army, on why he chooses a gun as his instrument for shaping the world.
His argument is the need for violence to control violent men, and that this is justifyable when the violence is the monopoly of the state AND accountable to the people (independent judiciary, politicos held accountable to the people).
I agree with his reasoning, and wonder what happens when the state looses its legitimacy but does not surrender its monopoy power on weaponry.

Consequences of human life extenstion -- Ken Dychwald
Right. So we can live to 120 or more.
What are we going to do with the time?
How will society adopt?
The tyrrany of the old??
Will we live healthily? What about dementia, which claims at least 25% of people over 70. What % of people over 100 will have dementia, in an age where life expectancy is 120?
What if life extension is only for the rich?

Prospect of human life extension-- Michael West
He discusses technologies which will enable us to extend human lifespan.
We don't know how long our kids will live. Technology currently working in the lab should extend their lifespans to 120 or so, but in another 50 years, the tech could easily be good enough to extend lifespan to 500 or so.
Attainable lifespan is growing faster than 1 year/year, meaning with each passing year, we gain more than one year of extra life.

The lean startup -- eric ries
Not up to linking this guy, he is a fad.
Release your software every 15 mintues.
How to build an IT startup.
Get some fans, some early adopters. Make your software do what they want.
Assume you are going to screw up, so plan accordingly:
make learning the explicit goal.
schedule the "pivot point" meeting early
Don't commit to a feature until you know it is wanted.
Shallow prototypes-- have a human make it work if you need to. (think Zapatos, who kept no inventory, but would buy retail to meet orders)

Trading rules
Nothing new, but nice to see people's lists. This from Joe Fahmy, clipped from ritholtz
Note also that these are rules for a trader, not an investor.
1) Accumulation and Distribution Days: When should traders go to cash? Follow the big boys! The big institutions control the market, so pay attention to their actions by tracking accumulation and distribution days. When institutional selling builds up over a short period of time (2-4 weeks) AND leading stocks start to break down, that is a great sign to start raising cash.
2) Uptrends and Downtrends: Don’t get caught up with the terms Bull and Bear market. Just recognize if we are in an uptrend or a downtrend. For example, use the 50-day moving average on the NASDAQ Composite as a general indicator to be in or out of the market.
3) Scale In: When conditions start to improve, SLOWLY scale back in. If the rally is for real, there will be PLENTY OF TIME to make money. If you are wrong, at least you can get out quick with minimal damage and protect your portfolio. Think Defense First!
4) Buy the Strongest Earnings & Sales Growth: When markets are in a confirmed uptrend, be in the best! Don’t settle for low rate stocks. Look for companies that have strong earnings and sales growth.
5) Fundamentals AND Technicals: Start with strong fundamental companies AND combine the proper technical timing to identify ideal entry points to effect your best risk vs reward trades.
