Does this actually contradict the weak form of the EMH, that "future prices cannot be predicted by analyzing prices from the past"? If it's computationally unfeasible for the market to incorporate new information, surely its then equally computationally unfeasible for some outside observer to predict future prices? I'm not sure this even contradicts the semi-strong form of the EMH, though it clearly does rule out strong EMH.

(this is serious because - as far as i can tell - this engine has a 330 minute ETOPS rating http://www.geaviation.com/press/genx/genx_20120308.html http://en.wikipedia.org/wiki/ETOPS which means that a twin engine plane (like the dreamliner) can fly 5.5 hours (the number in the report above) from "safety" (eg over the atlantic), so if one engine fails the other must continue working for that time. if the problem is common then that is not so reasonable an assumption...)

But, I do sympathise. I'm fortunate to live in an area where a lot of small businisses are around and about, and where widespread access to the internet means websites for local firms is actually a good idea.

But that's not the only local diversification!

I once taught programming lessons, for example, to people. That was kinda fun and challenging.
> Can I be considered prior art?

Short answer: yes.

Longer answer: yes, but only if the one single examiner handling this patent at the time had known of you, known how to contact you, and been able to obtain any information from you (and mind you, he/she likely could not have told you why he/she wanted the information).

The other problem is that while you did this over twenty years ago along with the others on the playground, where did any one of you publish anything describing your alternate swing method? Because to make a rejection stick, the patent examiner has to find some publication by you or one of your playground mates from twenty years ago disclosing to the public your new swinging method. This is because the position of the courts is that an applicant deserves a patent __unless__ the us patent office can prove otherwise (and "prove" pretty much means "prove to the level of a civil trial in court").

If the system were reversed, i.e. that applicant did not deserve a patent unless they (the applicant) could prove it was sufficiently new to deserve a patent, there would be far less of these "swinging on a swing" type patents.
A market can compute in some time period only that which is computable in that time period. The only one that says otherwise is the author of this paper, who then uses this assumption to prove... nothing really.

Some people just like it, I ran Slackware 13.37 in my laptop for some time: didn't really like it, but the community is nice and I like the "feel" of the distro, the package management wasn't that bad either (using SBOPkg).

Some people might say it's old and unnecesary, I say there are still people who love this distro, and maybe you will love it if you try it.
Rational actor model still reigns supreme.

EMH is taught globally and it will continue to be taught until such a point as people stop believing.
Pretty sure they are just doing what Apple is already doing. Apple's really closed and locked down platform is doing great, I am sure Microsoft is wanting to emulate them.

Going backwards. In some way Microsoft was more open in the desktop and the mobile (with the old windows mobile OS) than Apple.

> Dont you mean, "when you run slackware you learn slackware"? Otherwise the old adage is not true.

No he means what he said. There are no distro specific tools for Slackware. You don't `system-config-network` or `system-config-services`, you edit the config files. You don't run a tool to update which Java runtime is your default, you edit config files, or write a wrapper script for what ever applications need a specific version. Or do both, if you as the admin determine that is the right way to go.

You don't have a tool coming back and undoing your changes because you edited the file instead of using the tool. You're not reliant on a tool to enable or disable an Apache module.

You, as the admin, are the be all and end all. The distro is not second guessing you. There are no special tools to learn in running the system, just vi. That is why it was said when you learn Slackware you learn Linux.
In the Eurozone real GDP has contracted since the crisis according to this graph:

http://krugman.blogs.nytimes.com/2012/09/25/more-coulda-been...

So a lot of the "growth" is just the economy recovering from the austerity/crisis-related policies. The Eurozone's real GDP contracted 5%, so even if we then outgrow the US by 0.5% every year it will still take us ages to catch up.
> But to be fair, there are a lot of "projects" that can't stand alone

The problem is you can make more money by creating a project does not need to stand alone. The business plan does not need to make any business sense. You only need to get through the IPO.

FB cooked the books for decades trying to find a good time to do their IPO and they finally managed to get away with it. Some people made a lot of money on that IPO and a hell of a lot of other people got screwed!

But give FB 5 years and unless they can actually implement a business plan that works, not the work of fiction that is their current plan, they too will be gone.

Now because I suspect FB will be gone in less than a decade, to me that makes their IPO nothing more than a scam.

I guess time will tell.

> The grandparent described the environment being "exactly" like iOS.

Let me make my point clearer: I was talking about the ability of downloading and installing apps freely from the internet. What I meant was a closed ecosystem where you can only use approved apps from the app store without the ability to install apps from third partys.

That does not mean that you can't use the terminal or XCode (if those are approved apps), or get a "developer license" to "unlock" your Mac.
Is that so? Entering thepiratebay.org to Google search returns very relevant results.
Yes, that's what I thought. Ubuntu uses Debian's system with minor changes. If you want to say Ubuntu's package management is second (inferior) to Debian's, you need to show the changes are bad, not minor.
The social sciences don't have to because they aren't based on the scientific method - mainly the design and independence of repeatable experiments with controlled variables.

The same is true of many physical sciences - geophysics, oceanography, climate science, astronomy, etc. Your criticism applies to basically any scientific theory which has poorly understood microfoundations (i.e., a lot of them).

The EMH is taught because it's a useful approximation to reality, even if it's imperfect. Or, as the article puts it: Whether markets are efficient or not, and whether P = NP or not, there is no doubt that there will be markets that can allocate resources very close to efficiently and there will be algorithms that can solve problems very close to efficiently.

Incidentally, the EMH claims that financial crises are unpredictable. So the lack of useful predictions of the financial crisis is evidence in favor of the EMH.

> I don't understand the hatred of Java and love of JS.

I don't hate Java, but I hate to write the same application over and over again, one for every platform out there:

- the desktop web

- the mobile web

- iOS

- Android

- Windows Phone

- ...

With JS there is a little hope that we well be able someday to write the app once, and make it work on every device out there, if it is from Apple, Google, Microsoft, Samsung or whoever wants to enter the market next.

We are almost there, but we need hacks like PhoneGap/appMobi to make it work, and it's not optimal at the moment.
I'm not sure about that. With the way they've built gatekeeper it seems they might eventually set that to only allow installation of store apps by default but make it easy to turn off.

Did you edit your reply? Not sure, but I suddenly read my rebuttal and I sounded like a dick, so I toned it down. Sorry - unusually cranky this morning :)

The article is quite probably BS as you point out, and I have no idea.

However keeping an open mind seems like a worthy goal, irrespective of the BS that goes on in any field and even if the social sciences do tend to be less empirically rigorous.

And while it's exceedingly complex, there are indeed some people (albeit a precious few), that understand how the economic machine works. Ray Dalio is one such example.

Your point was worded as if Apple had a free choice, buffet style, of which features to have or not. Say Apple wants A but not B, and Google will only sell A+B. Your wording suggests that Apple turned down A, when really they turned down B, so had no option to get A.

Obviously, this is because PHP doesn't scale.
The MacBook Pro is not a closed platform yet. I can still create and distribute Mac apps in any medium that I feel like. On Mountain Lion, the default security options may make it a little more difficult to exectute apps that have neither been distributed via Apple nor signed with them, but there are entirely official ways of getting round this if needed.

I'm not saying that Apple won't go down this route for Mac at some point. But they have gone there yet.

>"If geeks weren't trading MBS and selling NInJA loans as AAA rated assets to the insurance companies"

I think you're conflating "people who work on Wall Street" with economists. Most of the "dirtiest" of the loan originators were people with no financial education whatsoever; salesmen, and nothing more.

>"If the Fed hadn't pumped easy credit, first during the dotcom bubble, then into the housing bubble, would the blowup have happened?"

Yes. Blowups happen. It's the business cycle. A credit driven economy inflates until marginal borrows default, which cascades to a deleveraging. The Fed "pumped" money in the economy after the dotcom bubble because we saw some of the greatest destruction of wealth, ever, during that period. And much of the housing portion was political mandate.

Admittedly, economics and the economy is a finicky patient. But contrary to popular belief, these guys are smart and know what they're doing.

I've read as much as I can about Windows 8, tried the preview, worked with a Windows phone.

Honestly, I can't see Windows 8 being anything but a colossal failure on the desktop, ala Vista. Everyone on the planet seems to be telling Microsoft to have two OS versions, one for mobile and one for desktop, but they are not listening. I would be seriously worried if I was a Microsoft investor, and I say that as a guy who's built primarily C# apps for the last five years.
This is a failed view. Yes, they've voted with their wallets, but "get over it" isn't the appropriate response.

Very very very well put! That actually holds true to many B2B sales scenarios - especially when targeting C levels.

Your point connected especially well with me since it rang so many bells with what I experienced when I was pitching my last startup (now defunct) in the live music industry.

Music and live music industry is a bit perverted in that it's such a "cool" scene to be associated with that it has a constant flux of fresh and very much free workforce available. As in humans.

This eventually created a bit of a conundrum in terms of value creation and pitching digital solutions to our prospecting customers - the live music promoters.

How exactly can you create value out of eg. time savings or better workflow management if the essential resource (workforce) is basically free and abundant. :)

Needless to say I'm not a huge fan of music startups in general nowadays for this particular reason since this problem basically permeates the whole industry through and through.

I have a hard time seeing a B2B / B2B2C service provider extracting a meaningful business out of music industry SMB's.

But I digress. :)
nah, redesign's been around for a while.
>"Economists have essentially no idea what is going on"

Complete and utter nonsense. "You" don't know what's going on, and assume others don't. The public is unbelievably ignorant of this subject. These men are brighter than you think.

>"EMH is by far the clearest example of this"

EMH is a 50 year-old theory. Like practically any other subject, economics that is taught in school at low-levels is based on old science. There is real, modern research happening on real-world things, just go poke around the Fed's site to see what they're doing.

Well I was really talking about the App Store. OSX and Windows both are going to have approved apps (the stuff you can get in their stores) then red headed step child apps that you get else where.

> I think it will be more along the lines with how they got rid of DOS. The command prompt still exists, it's just hidden away. You can't exit windows to dos like you used to be able to do.

DOS isn't a command prompt its an operating system. DOS wasn't 'hidden away' its gone. Windows 3.1 was really just a GUI running on top of MS-DOS. 95, 98, and ME used MS-DOS as a bootloader to get windows running, basically flipping the CPU into protected mode then handing it over to windows. The WinNT family wasn't built on top of DOS at all but rather has a standalone kernal. DOS programs were only supported by a virtual machine (and aren't supported at all in 64bit windows, DOS is completely gone there).

I don't see much connection at all between DOS and Metro, Metro is just a UI.
You really need to go learn some economics.

All of the topics you mention are popular topics of study. For example, gaming the system by influencing laws was studied by (picking a famous name here) Hayek. Monopolies/monopsonies are well studied and generally believed to be inefficient.

Information asymmetries and actors with bounded rationality are extremely popular topics to study today.

The paper we are discussing here is a perfect example describing the microfoundations of bounded rationality, for example.
How do I put tabs back on bottom like they used to be?
Well they still have two OS versions (although Windows Phone 8 now shares the Win 8 kernel). The real question is if Microsoft's long bet on tablets and touchscreen PCs being the future of desktops is a good one. For once, I think Microsoft is aiming big with its OS, and that's something to be admired. It's going to piss of techies, but it has a real shot at making tablets and hybrid PCs more useful for everyone else.

Also, it seems pretty clear to me that Win 7 is going to stick around for a long time, perhaps even longer than XP. That'll likely be the go-to OS for techies and people building desktops down the line.
To me stuff like this actually shows how some hard-science people apply autistic-like literal interpretation even to things that do not lend themselves to literal, narrow, interpretations. I'm sure, though, that many hard science people can expand their horizons enough to absorb different kinds of knowledge, too.
You can continue to install your things just the way you did in previous Windows versions.
You're probably right. I've only done graduate level courses in economics and finance so there might be PhD level stuff I'm unaware of.

I dunno, the mac store, and the fact that you now need to jump through hoops to run .app files you grab online seem like a solid step towards lock down to me.

I've been using Spectacle for a while and I am working on a port of Xmonad to OSX:

https://github.com/pufuwozu/osxmonad

So I was really interested in trying out this fork. A couple of problems:

* Doesn't look like tiling is automatic, you still have to tell each window which side of the screen to tile on (by using Command+Option)

* I was using it for a minute before it crashed - which I didn't even notice

If those two little problems were fixed I think I could definitely use this until I get my version of Xmonad working properly.
I think people will figure it out. But it would be interesting to do some usability tests on this.

I don't see any problem with saying that Android is not an open system. They use open source, but the way it is distributed takes away many of the freedoms of OSS. Also, most of the system is really in the Apps, many of which are closed source. In other words, Android is as much open source as the iOS is, because it is based on an open source kernel but the user space is full of non-open components. And good luck trying to contribute something back to the owners of the system...
