I think it can be triggered automatically when a major shift happens in a stock. I remember a few of these back in the 2000s when things were crashing left and right.
This has been out in the wild for a while now. I first noticed it when I added IAP to my application.
My app will call on our server to verify receipt and I was getting bogus receipts that actually caused that part of the code to crash.
Apple's receipts are proper json objects and what I was getting was this string "com.urus.iap.30297356." The last part keeps changing, so I am guessing the developer actually tracks usage.
So the moral is to always verify your receipts and don't deliver content unless the receipt is valid.
But most developers won't have resources to do this and creating a general service for them would be too much custom work. I think SDK platforms should have this capability built in. Pay $10/mo and we'll verify your receipt and return a file based on the IAP product id.
Can you clarify the phrasing of your cloud issues? Do you mean there is no solution for trust/privacy issues, or do you mean there is no solution for licensing?
As for paying, this is a non-issue, you are going to pay either way.
It looks like you are doing a simple frequency analysis to determine words for titles. In some cases it works, in others it reduces to just brand names. The Linux tab is filled with "Linux" for example.
Perhaps you need a learning filter that catches words that are too common and filters them out.
I think the point of the article is that being productive outside of the madness is more important for success than what you do during it. 99% perspiration and 1% inspiration.
Groupon and the like don't promote customer loyalty. They promote disloyalty. Why go back to the same restaurant when I can try another restaurant for 50% off?
Each vendor would have to evaluate with ROI with Groupon and no one really know how good or bad it is because it is likely to be kept secret. No one likes to be shown to be a sucker if it is bad, and no one will share if it is great.
