Both Shapley and Roth are microeconomists, so the fact that you are bringing up banking and inflation is a clear signal that you don't understand anything about economics. If you want to harp on Nobel Prize winning economists regarding their work on macroeconomic theory, you're 1 year too late.

Shapley and Roth deal with topics that fall, at the highest level, under the field of game theory, but more specifically market design. Market design relies heavily on mechanism design, which can also be called reverse game theory. In game theory, you're interested in determining the best strategy given a set of conditions (the players, their strategies, the timing of their moves, their payoffs and the information they have [or don't have]). On the other hand, mechanism design is concerned with what the conditions have to be in order to achieve a specific objective or outcome. Hence, mechanism design problems map well onto many problems of regulation.

For example, let's say there is a Senator, call her Mrs. X, who is interested in passing a bill that achieves outcome Y. The mechanism design solution is then the set of rules that lead to outcome Y occurring. Setting the right rules refers to Mrs. X drafting a bill that includes mechanisms such that every actor in the game HAS AN INCENTIVE to play the strategy/strategies that lead to outcome Y.

How does this fit in with market design? Well, besides generally using mechanism design to align the incentives of both the buyers and sellers, there is a deeper point to be made about market design here. All so often in economic theory it is assumed that a market already exists, and the analysis is then on understanding the inner functions of that market. However, what that type of analysis leaves out is how that market even came into existence in the first place. In what ways were incentives aligned such that both buyers and sellers found a match for one and other to begin with? In other words, why is this market here and how did it get here? These are the nature of the questions that market design tries to answer. By understanding how and why the actors in the market are doing what they are doing, you begin to understand how markets form. And if you understand how markets form, you can apply that know-how to the formation of new markets, or to improve old ones.
Cool demo. The 'gm montage' step isn't working for me and I'm finding its options completely non-intuitive. I produced a series of 1979 PNGs from a 66-second video, and when I stitch them with:

gm montage -borderwidth 0 -geometry +0+0 -tile x1 *.png image.jpg

I get an image that is 45, not 1979, pixels wide. In fact the number of PNGs used as input and the resulting width have a nonlinear relationship:

# of 1-px wide PNGs Resulting width (px)
5 3
10 4
20 5
50 8
100 10
200 15
500 23
1000 32
1979 45

Note that I made a couple changes: to speed things up I used "-vf crop=1:1080:280:0" with ffmpeg to skip the separate cropping step and output 1x1080 PNGs, and my version of gm didn't accept the -border option so I assumed you meant -borderwidth.

What's up with the crazy widths on the result? What is GraphicsMagick doing?

> This is not clear at all !

He is using 'type check' to point out the flaw. x = y means x and y are the same thing. If x is a function and y is an integer, then it can't possibly hold that x = y.

Consider x = O(n). The implication would be that whatever type of thing O(n) is, x also is. This is trivially untrue.

If x = y, and x is a function, then x(K) = y(K). It would be ridiculous to say that x(K) = O(n)(k).

> Yes well, f(x) = f(y) does not implies x = y. I think people know this ..

I don't understand why you are mentioning that. The issue is that x = f(z) and y = f(z), then x = y. You can't get two different values by applying the same function to the same value.

Saying that f is O(n), the "is" is not an equality statement at all, "is" is some other function exactly as you mention that people understand. It is clearly some function that is non-transitive.

In this case the relationship is most easily expressed using existing operators by having O(n) be a set of functions and the "is" in that sentence be the "exists-in" set operator, which is a case where the transitive property doesn't hold. Using the = symbol in that context is just bizarre when = is a otherwise always used to mean equality, which is function with special properties that don't apply here.

I think results like Shapley's and Roth's present an interesting commentary on the usual "philosophy of economics".

1. These results are all about finding good solutions to allocation problems without using money or in cases where money isn't or can't be applied.

2. These results do tend to show that a "centrally planned" solution can be better for everyone than a "free market" solution. But as you say, by central planning I really just mean that some entity takes in everyone's preferences and outputs a global allocation, with the nice property that everyone is happy with what they got and nobody can find a way to deviate from their assignment and be better off. One might argue that a "free market" would find the same solution eventually, but it might be slower.

These two results are sort of the opposite of the Invisible Hand stuff as well as the common assumption that, for instance, everyone values money the same (which underlies the justification for much of economics). So I think they're really cool in that respect.

I definitely wouldn't recommend doing it right when you want to watch the movie :) Generally I put it in right when I'm about to go somewhere else, so it's done or close to done when I get back.

Alvin Roth and Lloyd Shapley win Nobel for market matching theories
It says to 'ask PG a question', so I tried a bunch of things I thought would find plenty of results:

* "How to grow a userbase"
* "Find a mentor"
* "Disrupt a market"

Only the last one returned any hits. I definitely think it needs some kind of suggested queries for people to try out.
As somebody who actually has first hand knowledge of this issue (I wrote and designed the tracking for a major iOS ad network), I can say that this is an incredibly misleading article.

Here's what's actually going on:

- Apple has deprecated the UDID. We're still allowed to use it for a while, but in the long term it's going away.

- Apple has created a new identifier (the IFA), specifically for the use case of advertising. This identifier uniquely identifies a device across apps, but beyond that provides no information about the device or its user.

- This ID comes with strings. There's an option in Preferences to "Limit Ad Tracking." The terms and conditions specify that when this option is enabled, we still get access to the ID, but we are only allowed to use it for some specific purposes like conversion tracking (eg. making cost-per-action campaigns possible), and fraud detection (eg. preventing fake clicks). We are not allowed to use it to create profiles, or to improve our ad targeting algorithm. We are absolutely not allowed to divulge the information to third parties.

Without this, advertising wouldn't be possible. Some may think that that'd be for the best (myself included), but that's an entirely different argument, and you'd have to realize that the market would be very different (No free/freemium apps, and everything would be more expensive). You can't have your cake and eat it too.

I think it's not so much a business issue as it is a game design issue. A game that is genuinely of good quality should sell itself. Word spreads fast in the gaming world, so something that's unique or beautiful tends to draw attention without much marketing effort.

Now, whether your good game makes a small profit or becomes a massive hit is a whole other question. But to separate yourself from the big ocean of failed game projects, you simply have to have a deep understanding of what makes a game interesting, and to have a team that can execute that. There's not much you can do on the business end other than to keep everyone involved happy.

Luckily, the definition of a business 'success' in indie games is pretty modest; breaking even is pretty nice, and making enough to be able to start thinking about another project is a big success.

It's a silly complaint because putting most of the power in the most populated states is exactly how you'd expect it to work. California, with a huge population, should be vastly more influential than Montana. How much more influential? Well, I'd say about 38 times more.

Montana won't get much attention, but Montanans should get just as much attention per person as the rest of us, in that case.
Amazon Is Building A Hardware And Services Empire
Find your stuff faster in Gmail and Search
That's a pretty silly article, extrapolating from the already over-extrapolated musings of an analyst. It's asserting that "peak search" occurred last month (no time to wait! must be first to report!), based on a single number from a single analytics firm that says that search numbers declined year over year. The analyst leaves it at that, but the blogger has to take it further.

Also amusing: "Why The Google Era May Be Over"..."Google is not as bad off as it might seem".

In any case, if you look closer, you then see that the peak growth rate of searches in the last two years was only six months prior, and you start to realize why reporting on graphs looking through a one month window is stupid.

Personally, I would think that many people peaked in personal search years ago (there's only so many you can do in a day). What we're seeing is probably largely driven by population growth and expanding internet access.

Correlation != causation. If the numbers show that file-sharers buy more music than people who do not file-share, this does not prove at all that file-sharing leads to people buying more music. Maybe sharing of music files and buying music have a common cause: a passion for music.

It's just what you want to read in these numbers. People who download a lot of music (as in not buy it) unsurprisingly tend to believe in this causation without question.
i don't know without being re-born in an alternate universe, but i think there's a reasonable argument that i would simply give up on music - or just stick to a relatively small collection of classical and jazz standards. finding the good stuff is quite time-consuming; i wouldn't buy enough to do it and i'm not impressed with pandora (not that i can listen to it any more); radio doesn't cut it (except for radio 6 - i guess that would get even more middle age male listeners, but then that's free anyway ;o). in other words, as i think others have said: downloading is the new radio.

[updated: i'm not convinced this is a good-faith conversation, but if you're really curious, and not just wanting to say how you would do things - after asking what downloaders do, and saying you are not one, then dismissing my response - then i work like this: get a recommendation; grab an album; add it to random shuffle ("radio"); eventually notice certain tracks; become fans of those bands.]

The link I keep posting in conversations like this is the one where we wrote about the antagonistic relationship that "free", almost free, and flat-rate service providers enter you into:

http://blog.kozubik.com/john_kozubik/2009/11/flat-rate-stora...

It's different with dropbox, though, since their pricing (beyond the free 2GB) is not flat rate ... you really do pay more the more you use ...

Although I suppose that if the range is 10-200 GB, and you're paying $9 (or whatever) there is a pretty strong incentive to keep you as close to the bottom of that range as possible - and you can bank on their policies and system behaviors to reflect that incentive.

But the real worry with dropbox is just the unsustainable business model. It was illustrated so well with the backblaze-costco-drivearound-silliness - storage really costs something, and it's price sensitive enough that you'll drive around all week ripping desktop drives out of USB enclosures ... and if you're giving that away in a bubble 1.0 "anything for customers" model you should be worried.

Michael Blaha's Patterns of Data Modeling . This one has some interesting temporal, graph, and tree models.
http://www.amazon.com/dp/1439819890/

Martin Fowler's Analysis Patterns. This one skims some of the other patterns, but gives accounting a solid treatment.

They are all well-rated on Amazon and I have read them and they are all very good. A few are available on Safari too.

Explicitly. You can't share branches between repos, but git does a good job of making it look like you can. master and origin/master in your repo are physically different things from master in someone elses.
