    The "most expensive method possible" was not used.

    Well, name a more expensive method that still works and would fall within the budget.

    An excellent example of spending less money up front, but being forced to spend more later to work around issues on a compromised system that wouldn't have occurred if enough money had been spent on designing it right in the first place.

    A vast amount of money was spent up front. Keep in mind that they built a number of orbiters at roughly $2 billion apiece, plus development costs, and Earth-side infrastructure.

    The problem wasn't the lack of funds to build the Shuttle, but the design itself was too amibitious. I consider this essay a great explanation of the problem.

    What if they had intentionally bitten off a smaller task at first. What if they had retired the Saturn V, and slimmed down the staff for the Saturn IB (or better yet, auctioned it off or allowed the companies involved to commercialize it), and then done a much smaller first generation âoeshuttleâ? This shuttle might have only been capable of putting a couple thousand pounds into orbit, and might not have gone straight to an operation vehicle. This wouldnâ(TM)t have been a program trying to keep as much of the Saturn team together as possible, or an attempt to replace all existing rockets in one fell-swoop. It wouldâ(TM)ve been an X-vehicle in reality.

    In other words, keep the Saturn 1B and build a much smaller shuttle capable of carrying 2-4 people or in the unmanned version a ton and a half of payload. I think the US would have much more than a space program these days, if they had gone that route.

    That's true. The real problem is the liability. Looking at your example above, the organization in question doesn't need to train the drone pilot to the same level as the helicopter pilot because less lives and property damage are at risk. That means, if something goes wrong, you're out the cost of the drone plus whatever it hit. With a helicopter, that's at least a pilot and a much larger footprint on the ground.

    Yeah, I see what you mean, but now we know. We didn't, before. And whatever we do in the future, we'll try to avoid those problems (as new ones are created).

    That's a rather empty thing to say.

    A lot of Slashdotters like to compare the cost of the Shuttle to wars in Iraq and Afghanistan. So would it make the wars and the vast sums spent on them ok, if I just observed that "Now we know, we didn't know before"? And of course, "We'll try to avoid those problems."

    It's especially empty since we really did know ahead of time that the Shuttle was going to have most of the problems it had. Obviously, not the oblivious NASA managers who were forecasting a bunch of nines (1 in 100,000 prior to the Challenger accident according to Feynman) of reliability for the Shuttle. But it doesn't take a rocket scientist to look at the budget for NASA (even back in 1970 when things were starting to draw down) and see that there wasn't both money for the Shuttle and money for interesting things to do with that Shuttle at the same time.

    Nor was there surprises for those who look at actual reliability of rockets. Accidents were bound to occur which for NASA caused at least 4-5 years of cessation of launch activity.

    And we can see with the Space Launch System funding, that US Congress and the NASA supply chain aren't interested in learning from their "mistakes". It looks to me like the US is about to repeat all the mistakes of the past half century again.

  6. Re:Alice is not aware of Bob and vice versa -Eve w on Mysterious Algorithm Was 4% of Trading Activity Last Week · · Score: 1

    The attack is only possible due to being able to communicate much faster than a human could. A human can put in a lot of failed bids to find out Alice's lowest price, but in the mean time Bob could have put in a successful bid. A high frequency trader can do that long before Bob can put in a bid.

    Well, you just said above that it works better when it's faster, not that it becomes impossible at human speeds. In addition we need to consider the nuts and bolts of what's going on. Basically, in the above scenario. Alice is running a computer program not a limit order and selling to what appears on the market. So no matter how fast the HFT is, it can only respond to Alice's activities as her program makes them.

    Now she might have a stop order which is a trade that operates at HFT speeds. Then it becomes to some degree worth poking around to see what triggers when one creates a small "flash crash".

    Or she might do a bunch of market orders which are also operating at HFT speeds and very gameable once you know the timing of her activities (say she sees your book order and then 200 ms later sells 500 shares to market). An HFT trader can drop their buy order (in practice they'd be putting up a buy order for short periods of time, long enough for it to register to program traders and short enough that it doesn't have much chance of getting triggered) in that short period of time and pick up those shares for even less than what Alice thought she was selling them for.

    But these sort of things are simply bad trading tactics for Alice in a market where HFT traders are known to lurk. That's why it's not a traditional man in the middle attack.

    Thus Eve does have special knowledge of Alice or Bob's price thresholds at which they're willing to trade.

    This is a typical market maker advantage.

    I think your "covert" limit is a completely irrelevant figleaf

    The covertness is a standard part of the definition of man in the middle attack. If you know Eve is there, you'll behave differently than if you don't know she's there.

    Besides, if Alice is never aware of Bob due to the speed of the trade doesn't that even fit your artificially narrow definition?

    Technically, none of the three know of each other aside from the very limited actions they have via the market. But they know there's other people on the market including HFT players doing their thing.

    to get away from your ridiculous assertion that 70% of all trade has little impact on the market.

    As I stated earlier, it could be 99.9% of the volume on the market and still be as irrelevant as it is now. Market makers have always had a high part of the volume of the stock market. And they don't accumulate stock. So in the long term it's only the people who want to buy and sell long term the stock who actually have the stock. In terms of a communication channel, HFT is noise (and even at high volumes, just not that much noise) and long time scale trade is the signal.

Too expensive, capabilities that the military didn't care about (like putting seven people in space), other capabilities that weren't that good (small payload capacity for the size of the vehicle), and the operator, NASA wasn't under the control of the military (as I noted in my last post).

  8. Re:Need me to draw you a diagram? on Mysterious Algorithm Was 4% of Trading Activity Last Week · · Score: 1

    Alice with the assets wants to sell. Bob the broker wants to buy. Eve wishes to profit by inserting herself into the communication channel and buying at the lowest price Alice will sell at then sell at the highest price Bob will buy at. This works if Eve can communicate to them much faster than they can communicate with each other - hence HFT.

    There are numerous problems with calling this a man in the middle attack First, everyone knows that there's a bunch of Eves present. So it's about as covert as a parade, which fails one of the standard non-personal conditions for being a man in the middle attack.

    Second, Eve has no special knowledge of Alice or Bob's price thresholds at which they're willing to trade. So Eve has to trade with both Alice and Bob when they show up on the market in order to probe out the price thresholds of each in turn (unless they're slapping down long term limit orders, in which case a trade occurs whether Eve is there or not). Alice and Bob have no reason to care, because that's why they're there in the first place to make trades at the price they want to trade at. They don't care whether they're trading with each other or the many Eves in the markets.

    This is also an activity that a human can do. HFT just does it a few orders of magnitude faster.

    Finally, in the case where Alice and Bob aren't actually putting up long term limit orders, they don't know about each others' willingness to trade and no trade occurs until Eve closes the sale. So this man in the middle (what we would normally call a market maker) is not "attacking", but an integral part of the sale. This incidentally is an example of how an HFT trader can provide liquidity to a market.

    such as your bullshit that it has to be "covert".

    That's part of the standard definition of a man in the middle attack. It's just a reasonable point.

    As far as money goes, and spending it wisely, over its 30-year run the shuttle program ended up costing us just under $200 billion in 2011 dollars, as well as 14 lives.

The current estimate of the cost of the Iraq and Afghanistan wars is between 3.2 and 4 trillion dollars, with over 4400 Americans killed and over 33,000 wounded in Iraq alone. Afghanistan has cost us another 2100 American lives, and those numbers don't even include non-Americans or civilians. In 2008 alone Bush proposed $190 billion for the wars, just under the total cost of the 30-year shuttle program. I'll leave it up to you to decide which is the better investment.

    I see war cost estimates a third of that. And funding a couple of years of a war in a critical region to the US does seem to have a lot of value compared to coming up with the most expensive method possible for launching things into space.

    Look at that list. How much clean water can you consume? Light? Food? Sanitation? And education? Those are inherently limited in demand and something you can readily pay for past a certain point.

    Demand for health care is not limited in the way that it is for these items. For example, clean water has controlled marginal costs. If you want a little more water, then that's a modest cost. It is too easy to spend tremendous sums in order to get slightly better health consequences or a little more lifespan. There's no clean line where you can say "This is a reasonable standard of health care."

    And we can see with Obamacare and subsequent regulation that there really is a slippery slope here. For example, employer insurance is now required to fully cover the cost of birth control. That doesn't make sense to me even from the moral viewpoint of the supporters of the regulation. It's too easy to buy cheap but effective birth control.
