Private R&D for an ekranoplan-size aircraft might be difficult, but if it could work just as well for smaller aircraft, this might be an option to consider.

Does anyone know if the ground effect is affected by wingspan?

-----


The high efficiency of the ground effect starts dropping off sharply at 1/2 wingspan altitudes.

(Anybody who's flown RC gliders will be very familiar with this.)

Because I would like to know about scalability issues?

Perhaps in these two years their userbase and the number files saved every 15 minutes might have grown by, say 5x and 50x, revealing problems that were not visible in 2011, leading them to modify the system from what is mentioned in the article?

What is stopping the server from being taken down by legal pressure?

How would you go about marketing this? I don't know much about the e-commerce site creator market, but what separates you from the competition?

-----


Right now we're focused on smaller shops, price wise we offer a lot more features, multiple payment gateways, complete custom themeing and also marketplaces that you can showcase your products in for no additional cost. VNTGE.net is the first marketplace that's been built for vintage and antique goods.

*First as in first mmerch marketplace, not first ever.

It shows that it has been a labour of love. Kudos!

My 2 cents: I would like to have a "View store as customer" link, which shows a preview of the store. I created a single dummy product and tried accessing it at https://memememe.mymmerch.com/ which threw an internal error. Also, the Add Product page is a tad long and would be better if broken up into 2-3 pages.

Again, great work! Good luck.

You have to go to the settings page to find this, but apparently, you can access the demo at https://demo.mymmerch.com.

Edit - I just tried that link and it throws an internal error as well. Sorry!

Murphy and his stupid laws :)

Hmm, I haven't had that issue before, but i'm certianly seeing it now, I'll check that out tonight. Thanks alot for the feed back

How is

    int*int*int*int*int
or even

    int^5
better than a plain int[5]? To me, the use of mathematical operators * and ^ causes dissonance.

-----


If you're coming from a type theory background (which, granted, few are), this operator is actually perfectly natural.

-----


I don't come from much of a type theory background. I certainly have no formal education in the field. I just know how a Cartesian product works, and that's enough to make me get it.

-----


Aren't product types just tuples, whereas arrays correspond to list types? The '^' operator can only construct arrays whose elements are of a single type, right?

-----


That's correct. However, somewhat problematically, Felix considers the tuple int * int to actually be an array int ^ 2. It's not entirely clear this "automatically applied isomorphism" is a good idea though. However it means arrays "drop out" of the notion of a tuple as a special case.

Internally such arrays have a special representation which allows arrays of 100,000 values, something which could never be represented by a tuple type (and still get reasonable compile times :)

-----


Thanks for the tutorial! Just a small suggestion: Syntax highlighting would make it easier to follow the code. You could probably use a library like http://balupton.github.com/jquery-syntaxhighlighter/demo/

They implemented map and reduce in separate js files and used bit.ly to store the intermediate results.

What meaning does the per capita normalization have, other than "n people registered and m people completed it", and in what ways is country-wise data useful?

-----


jaipilot747: It means normalized by the population of the country.
