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?
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.
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 :)
