If your friends want to sell anything online my advice is to be a company that sells products online that just happens to also use Amazon. Don't be an Amazon seller exclusively or you might live to regret it. They can shutdown your account for almost no reason or any reason at all with absolutely no recourse whatsoever. They can suspend any of your listings and give zero reasons. They will hold on to your money and keep it hostage.

All I have to do as a competitor to royally fuck you up is have a few people buy your product/s and then contact Amazon to complain that they are counterfeit or somehow not as represented by the listing. Boom! Listing shutdown, account suspended or both. If you call Seller Support for help the story you are likely to get is the the "Seller Performance team does not share the reasons for which they take certain measures". Boom! Again. You just got shafted, have no clue why and have no recourse. All you can do is wait and see what the internal Amazon process might decide.

I have a friend who was in a similar predicament. He was forced to have all of his inventory destroyed because it would have cost so much in shipping to recover it from Amazon warehouses that telling Amazon to destroy it was a better option.

I'm assuming you're talking about canker sores. I don't know how much help this will be to you, but here it is anyway:

You may have tried these, but I've found the best ways to dull the pain are swishing 50/50 Maalox/Benadryl and using a styptic pencil.

Also, I've found in my case that what helps most to prevent them is keeping my mouth as clean as possible. The two main causes I've identified are illness and physical trauma to the tissue. The worst offender is the crap plaque excrete; it eats away at tissue, and I've found more than a few new sores under a stray piece of lunch. Oh, and I've had far fewer sores since I switched to an SLS-free flavour of Sensodyne.

Personally most American furniture I see in real life is not up to the standard of design I see in and around Stockholm.
That's really interesting. So you could put $200M of assets into a Vanguard fund and only get charged $40k/y for that. It seems like a very small number when you put it that way.

That was also my impression, especially considering that CMU has a Machine Learning department (above and beyond their existing Stats Dept.) and there are Data Science Master's programs popping up all around. Get on the bus!

The politics and turf battles must be fascinating, because if there is one (technical) discipline that feels encroached-upon and under-appreciated, it's statistics. Finally, some appreciation, and they'd hate to cede any control to (say) a bunch of upstarts from the CS dept. who wouldn't know a James-Stein estimator from Adam.
A couple problems with that --

1. Studies that say "XX% of active managers don't beat an index" include every tiny poorly managed fund. The best attractive lots of capital; Bridgewater has $169 billion under management and has a long track record of large outperformance.

2. A lot of investors aren't trying to beat the market per se -- that's in your own link. If you own safe investments during a bull market, you underperform... but if it (ideally) makes you less susceptible to both boom and bust, that could be a good trade depending on what you're doing. If you're an insurance company or pension fund, you probably want stability more than squeezing every last basis point out of your investments.

Anyway, I could give you many criticisms of many aspects of finance, but I think "index > active management" is a bit simple.

I completely agree. I interviewed with a company, and did some whiteboard coding. Most of it was simple, but whenever I would stop for a moment to think about what I was doing, they would prompt me to find out "what are you thinking"?

None of your complaints are about Windows. They're all, almost universally, about OEM and third-party shovelware.

You can't separate windows from its ecosystem - it's allegedly the choice of vendors and the availability of commodity hardware that makes windows at all appealing for most computer users. And the windows ecosystem sucks - it's full of weeds and parasites. Windows can't be examined in the abstract - if 99 out of 100 randomly chosen configurations in the marketplace are just terrible, then that's just Windows. It's the incredible leeway that Microsoft gives IHVs that makes Windows as popular and at the same time as terrible as it is. That's what characterizes Windows. As an operating system, it isn't half bad (it's architecture is quite good, actually) . As a platform, it's terrible.

See, you're doing it again. You're not dealing with "Windows issues", you're dealing with issues on Windows boxes, caused by non-Windows problems

What exactly is it that you're arguing? It seems like you and the parent are largely in agreement and you're trying to generate friction.

I would contend that you're right that it's absolutely true that with enough research and with constant vigilance, you can bring a retail Windows system into an acceptable configuration, have all of your hardware enumerating properly, and avoid malware.

I would contend that the parent is right that maintaining a Windows system is just barely worth it if it's your own machine and is a hopeless time-sink if you're doing it for free for anyone else, like family.

Are you two really just arguing past each other?

The point here, though, is that you're not an idiot. Your family aren't idiots. You're just all too lazy for your own good.

For more on CLOS, "Object-Oriented Programming in Common Lisp" is a fun little book. It has some reasonably practical examples and touches on just enough of the system's low-level details. It doesn't have much to say on the Metaobject Protocol, though, and I think for that "The Art of the Metaobject Protocol" is pretty much the standard text.
Heh. I thought it was going to be animated.
Bright article for once.

But, such a shame people don't understand what survival to the fittest means.

Bombers/planes are expensive. Some people think that if you are rich then having expensive toys is good. Less people are able to buy them so you should win the wars against almost all poor countries.

Right, it is a basic asymmetric situation. Survival to the fittest, is about using your advantage.

Well, how expensive is it in a poor country to build and destroy an expensive plane?

Stealth plane are stealth. They tend to absorb waves. Thus if you have a distributed grid of electromagnetic emitters you probably have a very cheap radar very efficient for detecting stealth plane. Once you have a vector, shooting a plane that has a given cone of future is quite trivial.

Well, that is called a mobile network. I am no genius, but I see a potential for reverting the assymetry. Ok, maybe I am wrong. But, war is assymetric. If you can invest 1% of the sum in military expense compared to your ennemy to defeat him, then you win in much more cases.

The fighter vs missile is known since they droped the MACH 4 plane studies (dassault).

The point about war is we can't prepare for it because we never know how it will look like.

My stupid opinion is: it is better to avoid war, and invest the saved money in education of fine citizens that will be smart in face of a new situation called war so that we may survive.

But one can also build very expensive planes... that can be defeated with very small cheap education.

> their patients can reliably take the 3 seconds to swallow a pill everyday

This isn't even close to being true. Compliance is one of the biggest issues in modern medical practice. And people who reliably take the three seconds to swallow a pill every day are much, much healthier than people who don't, no matter what's in the pill.
It is possible for an observer to accelerate uniformly from their own perspective for an indefinite period of time in special relativity (the motion traces out a hyperbola in spacetime asymptotic to the lightcone). The person undergoing the acceleration doesn't notice anything changing as time goes on. All of the relativistic slowing down and time dilation effects etc. that you mention are seen in an inertial reference frame looking at the accelerating ship.

http://physics.stackexchange.com/questions/53587/if-a-space-...

From the ship's frame, the acceleration would continue at the same rate. However, due to Lorentz contraction, the galaxy around the ship would appear to become squashed in the direction of travel, and a destination many light years away would appear to become much closer. Traveling to this destination at sub-luminal speeds would become practical for the onboard travellers. Ultimately, from the ship's frame, it would be possible to reach anywhere in the visible universe, before the ship has time to accelerate to light speed.

http://en.wikipedia.org/wiki/Space_travel_using_constant_acc...

If you can build an engine that can constantly accelerate, without having to constantly throw fuel behind you, e.g. http://higherperspective.com/2015/03/nasa-engine.html, an astronaut can potentially travel 4 light years in less than 4 years, from their point of view, because although from Earth's reference point of view they will always be less than c, as their speed approaches c from Earth's point of view, there will be time dilation between them and Earth. If from Earth's point of view they take 4 years and a bit to travel 4 light years, assuming acceleration to very close to c very quickly, you as an astronaut will experience the same time as a lot shorter, possibly as months.

From the astronauts point of view, they can travel one light year in less than one year, if they can accelerate constantly fast enough without dying.

Of course I haven't taken into account the amount of energy that needs to be involved, except to say, if you're talking about a one-way trip, the time factor can be overcome, through technology that isn't that impossible.

If you know what's on the other side and it's possible can build a self-sustainable colony, colonising other planets is perfectly feasible from a psychological point of view given we have the technology we can accelerate close to c and decelerate from c, by achieving the time dilation effect.

IANAL but assuming that the author making this license was in US, it is totally void. It could lead to a court having to formally state that a software is not a legal entity, which would be interesting, but I think the result is clear that this precise software would not be recognized as one.

You can't transfer ownership of anything to a non-existent entity. My guess would be that such a transfer would be void but it may be possible that a court decides instead that this means a transfer to public domain.

Waving away the responsibility of other people does not work either. You can't claim that your car is responsible of the accidents you drive it into. Likewise, it is unlikely that any court dismisses the responsibility of the first person that will turn this into a malware.
Relevant to this discussion is Warren Buffet's 1975 memo to the board of the Washington Post regarding investment strategy for their pension fund. He advised being patient, investing like an owner, and eschewing highly paid money managers. A quote from the memo:

"If above-average performance is to be their yard stick, the vast majority of investment managers must fail. Will a few succeed — due to either to chance or skill? Of course. For some intermediate period of years a few are bound to look better than average due to chance — just as would be the case if 1,000 ‘coin managers’ engaged in a coin-flipping contest. There would be some ‘winners’ over a five or 10-flip measurement cycle. (After five flips, you would expect to have 31 with uniformly ‘successful’ records — who, with their oracular abilities confirmed in the crucible of the marketplace, would author pedantic essays on subjects such as pensions.)”

At the time of WaPo's sale to Jeff Bezos, the pension fund had a $1b surplus.

This article describes the memo, and includes a link to a PDF (thru Scribd):

And the simple model is wrong. Here is why.

If you are a customer for hedge funds, you should be willing to pay anything up to the expected future alpha based on past correlations between previous and future alpha.

That correlation is always affected by regression to the mean. Therefore someone with a good track record will not be able to charge on the expectation of future performance matching past performance. But only on the expectation of future performance being somewhat better than the market mean.

The ideal if everyone does everything perfectly is that, on average, fund managers that can generate excess alpha will, again on average, capture their entire outperformance as fees.

Just a couple of weeks ago I got back into reading books again, and mainly scifi. It feels great to read again!

I loved The Forever War by Joe Haldeman, recommended previously in this thread, and that got me to Old Man's War by John Scalzi. (It might be interesting to note that Ridley Scott has hold the movie rights to this book for many years now. I can't see it really becoming a mainstream movie without cutting out some themes from the book.)

The theme in Old Man's War are sort of the same as The Forever War, but in such a minor way that it didn't bother me even once. Scalzi then turned that book into a series, all very well worth reading (except Sagan's Diary - give that a miss). After his Old Man's War series I read Redshirts (so and so), Agent to the Stars (good read) and now I'm reading Fuzzy Nation, which is shaping up nicely.

In the afterword to Agent to the Stars Scalzi actually recommends other scifi books, and per his recommendation I tried out Stranger in a Strange Land by Robert A. Heinlein (of Starship Troopers fame) but that quickly grinded to a halt. Might give it another chance later.

Oh, I also read Haldeman's Camouflage. Seems to be liked by the reviews I find online, but I found it to be a waste of time due to a very weak end chapter.

After this I plan to dive into Rama territory and perhaps Dune also.

Please keep the book recommendations coming, this thread is a goldmine. :)
Perhaps, and furthermore Earth's surface-to-volume ratio would increase quite a lot more shortly afterward, as its shattered remains spread throughout the solar system. I imagine that the Earth would cool off rather quickly, or what's left of it anyway.

I think I could actually evaluate the price it would cost for building this radar in one year (and quite a lot of cash for asking people that knows more than me) and give and exact amount of money for building it. And one more year for asserving missile on the target. And this means that we can know the cost of this idea for a fraction of the cost of the F35. Which at my experience means that it might cost just an order of magnitude more than the money to evaluate.

Which still means that I am amazed at how much money we spend on expensive weapons that one can defeat with far less money.
You can guess at trends from the fact that most improvement curves tend to be roughly exponential. Moore's law is the most spectacular, but similar (if less extreme) ones have been found in everything from battery capacity to the maximum size of scoops in a hydraulic backhoe.

You can find verification and many more examples in The Innovator's Dilemma.
The revenue model for investment managers is an annual wealth tax on their clients no matter how bad the returns! Hell of a way to charge fees, huh? Would we all love it if computer programming services were charged as a percentage of the market cap of the customer who needed the work done! But it's Wall St so everyone just accepts a wealth tax model. Then we take them seriously when they repeat their bullshit when to distract from their wealth destroying fees they scream "HFT" "Short Sellers" "The Frickin' Bogeyman"
The problem you are referring to is called the expression problem [0]. There are solutions, such as the Visitor Pattern, but these tend to increase complexity substantially. Functional programming has approached this from the other side by introducing something called protocols [1].

"The cluster centers found by STS clustering on any particular run of k-means on stock market dataset are not significantly more similar to each other than they are to cluster centers taken from random walk data! In other words, if we were asked to perform clustering on a particular stock market dataset, we could reuse an old clustering obtained from random walk data, and no one could tell the difference."

"As the sliding window passes by, the datapoint first appears as the rightmost value in the window, then it goes on to appear exactly once in every possible location within the sliding window. So the t_i datapoint contribution to the overall shape is the same everywhere..."

"Another way to look at it is that every value v_i in the mean vector, 1 ≤ i ≤ w, is computed by averaging essentially every value in the original time series; more precisely, from t_i to t_m-w+i . So for a time series of m = 1024 and w = 32, the first value in the mean vector is the average of t[1..993]; the second value is the average of t[2…994], and so forth. Again, the only datapoints not being included in every computation are the ones at the very beginning and at the very end, and their effects are negligible asymptotically."

The biggest sham is that Wall Street has convinced us all that they deserve to paid in percentages! Sure %0.2 doesn't sound like much until you realize its $200 million dollars a year. Why is everyone so afraid of just hiring a few smart economists paying them $200k each salary? Nobody really beats the market over the long term anyway.
I'm a bit confused about what the author means when he says that managers should charge equal to the extra value they add to a portfolio.

Why should I hire a manager that beats the market, he he charges the amount he beats the market with? Wouldn't that leave me of the same as simply averaging the market?
Ah yes, I think this was one of the first things I looked for this in particular at the first run when I just got my first Amiga. Brings back good memories!
