Basically by being a skin tight suit the wearer is better equipped to handle long hours in a space suit, right now something like 80% of an astronaut's exertions are fighting the suit, with 20% left for actually working on the Space Station or Hubble or something.
In 'the future' we're going to spend a lot more time outside doing things, on orbit, on the moon, on mars and it'd be a lot better off if we didn't have to fight the suit to do the work.

So looking at the article, but not the study itself, people are submitting their projects to Coverity for static analysis, and 11,200 defects have been eliminated with the ehlp of the program.
Article also says 60 million unique lines of code were scanned on a recurring basis from 280 projects.
11.5 billion lines of code, with one bug in every 4,000 lets say that's the top line number that their software kicks out almost 3 million bugs. So are there 3 million bugs in all of open source?
At my last posting we used FxCop to analyze our VB.Net software and it found 3-4,000 errors, now what the tool looks for is wide ranging but all but two of these findings were Variable Naming conventions and best practices developed by the.Net development team.
The 2 we fixed said Variables did not have Strong typing and another Security option turned on when the executeable was compiled.
So what is Coverity's definition of a bug?
Now if I had the definition of bug, are any of these bugs in common libraries? Were any of them copy pastes from other software that could be fixed on a one to many basis?

Excuse me,
Just what was the 1960's "Apollo Engineering Mindset" for getting 2 years worth of fresh water to Mars for each crewmember? How about 2 years worth of Fresh Air? What would you do about bone loss, muscle atrophy for that same time? I leave as an exercise for the reader what the longest time in space was in the 60's but it wasn't anywhere near 2 years a Mars trip would take.
Lightweight and hard (not necessarily strong) are not necessarily what you want in a bullet. Hard bullets destroy the rifling in the weapon. There are smoothbore guns, but not too many. Lightweight bullets don't retain their energy well over time.
The trend in artillery is for really heavy rounds, like Depleted Uranium or thin Tugsten spikes launched inside of a Sabot. If anything came from this in a prjectile I assume it would come from the Silver Bullet style like the high speed tugsten spike.
Oh yeah, not to reply to myself, but shortly after high school I did some patent drawings for a cylindrical weapons mount you could load into a 120mm smoothbore cannon and inside the mount you could configure a.308,.50 cal or 25mm match grade barrels attached to an trigger mechanism that could be activated remotely while loaded in the main cannon of an Abrams.
This was supposed to be used for training purposes using ammo already found in the US Armory stores.
IIRC they went with a German training aid instead.
There are several rifles and pistols that can be changed to accept different barrels and actions into the receiver. These different parts shoot ammunition of different sizes.
I would assume this is a bench mounted receiver that can be triggered remotely. Kind of like the mythbuster's Curve a Bullet Robot. This is done to make each shot as mechanically similar as possible and without endangering a human shooter that shouldn't be on the range on an armor defelction test.
Why not have a bench grip or vise? The handles of these weapons are probably screwed into the mount, not gripped in the traditional sense.
Ok, we know of critters that live on Sulphur and not Oxygen
We know critters that live in deep oceans without sunlight in extreme cold. We know of critters that live in lava vents at high temperatures.
Nothing we are aware of lives without solvents, carbon or raw materials. Grandparent could have been implying that Earthlike Extremeophiles might be able to live on planets similar to Mars, Venus, or Saturn's moon Enceladus.
The new bands of benign environmental conditions between what can be tolerated by cold and hot extremeophiles certainly extends the Goldilocks Zone where life as we know it can live, and I'm glad this new work is taking advantage of that.
The nut of the question is did our extremeophiles develop in extreme environments, or a benign one and evolve into the niche loving extremeophiles we know and love today. The without regard for how it happened on Earth, is it possible for life to develop in these extreme conditions elsewhere.
The first part of the question is important because the atmospheric conditions we have today have not always been the same. The Earth was once hotter with a denser atmosphere, perhaps their new equation should take this into account as well.
Ignore the writer talking about his own strategy, and the boxing metaphors, the Nobel prize winning father or Behavioral Investing has had his own Investment funds rated Below Average by Morningstar, and a 2006 study of Behavioral Investing funds found
...in a 2006 research study by three finance professors from Florida State and Central Michigan universities. They analyzed "16 mutual funds that are self-proclaimed or media-identified disciples of behavioral finance," including the two Fuller-Thaler funds. Conclusion: "Behavioral mutual funds are essentially value funds [and] exhibit no ability to time risk-return opportunities" because "investing based on the principles of behavioral finance is indistinguishable from value investing."
In addition to being about the same or worse as a Value Investing strategy, they have high stock turnover, bad for you at tax time and fees tend to be higher, bad for your returns.
> Elon Musk testified before congress that they have plans to get costs down to $500 per pound.
p>Falcon 9 hasn't flown. It has not demonstrated safety, load capacity, turnaround times, manufacturing capability, payload handling, or basically anything. So yeah, it will be great if he can do it. But odds are that he can't, going by the historical record.
The Historical record of two aborted launches and everyone thought they were doomed, now they do regular cargo launches. The historical record of commercial aerospace in general? The historical record of GM and Ford (Establishment) telling him he (Tesla motors) couldn't build a plug in Electric Vehicle?
To answer you launch cost statement, costs for the Falcon 1 are currently $7,000 per pound, and $4,100 per pound for the Falcon 1e. Still one half to a third of your $12,000 per pound figure. And Falcon 1 launces are happening now.
Musk also mentioned a heavy lift vehicle NASA has an option to have them build, I am assuming this is aligned with the $500 per pound number.
I'm not on the laser broom bandwagon... my notion on the debris problem is to build a space roomba.
The idea is a big mobile catcher's mitt made of Aerogel or the NASA foam that Bigelow uses for their Habs, match velocity with the debris, and even if it penetrates the gel/foam, the debris loses velocity in the exchange, and eventually falls into the atmosphere. The normal case is expected to absorb the debris into the gel/foam.
Now, further affecting your numbers might be either taxes/penalties on CO2 emitting power plants which would drive the true cost per kWh up, the mandates by several governments to buy 20% of their power from renewable sources such as solar (at any cost) and a tax rebate up to 30% on building new renewable energy power plants. All three of these things will distort the market price for power away from coal.
I was looking at a white paper for Laser based Solar, and they were using Infa-Red Diode Lasers with 50% efficiency to beam down to a concentrator that was focussed on a 20% efficient PV panel on Earth. I asked why they couldn't focus the concentrator on a 27% efficient Stirling Engine instead. I haven't seen an answer back yet.
SpaceX has published launch costs for the Falcon 9 Heavy @ $2,726 per pound, and Elon Musk testified before congress that they have plans to get costs down to $500 per pound.
Chavez promoted the use of traditional toys like the Yo-Yo and Trompo, and suggested that electronic toys like 'the Nintendo' be put aside because they promote 'egoism, individualism and violence.'

I am not aware of any golden age when it was common for a person to work his way out of poverty by selling his labor power.
The point of capitalism is not to lift up the employees. The point is to take their work and pay them less than the amount of money it generated for the business, while pocketing the difference. There'll be anomalies here and there, but it's never been normal for employees to be paid in proportion to the value they create.
Then you missed the entire Industrial Revolution, the coming of Labor Unions to protect laborers from exploitation. There were anomolies in there where men of vision made money and poor craftsmen and laborers made money. A lot of rural farmers left the fields for the cities to make money. There are historical studies that say the early 19th Century destroyed the skilled craftsman, by replacing their skilled labors with cheaply manufactured goods. However by the end of the same century the laborers that operated the machinery were making more money than the craftsman did at the beginning.
Henry Ford paid his employees a good wage, enough so that they could afford to buy the cars they built.
His cousin sued him over it, because he wasn't maximizing shareholder value. This was the beginning of the duty of the company is to maximize shareholder value meme. By the end of Ford's tenure they didn't know how much it cost to make a car. He did a lot of Philanthropy, some of it misguided, in hindsight he probably should have taken the company private if he was going to do the things he did.
As to your last parting shot about employees not paid in proportion to the value they create, I think you mean laborers, and unskilled workers in capital intensive industries. With skilled workers, you almost have to, if you don't, they take their skills and start their own company competing with yours. Either that or a competitor will arise from outside the company with lower magins.
