Apple stuns WWDC crowd with pulsating App Store hyperwall - Page 3

My guess is that it requests the latest sales data from the server every five minutes. Updating in real-time could significantly slow things down for people actually purchasing apps.

Then, the way the data is time-distributed on the Mac displays is just random over those five minutes.

That's how I'd do it, anyway

As a database programmer by day, here's why I routinely export things in batch...

Unless you can insert the export functionality into the transaction as it happens, the only way to capture the data is to look at the entire data set after the fact and select only those records within a time/date range. That select can be resource intensive so the solution is to do it periodically. Or actually, the only solution is to do it periodically if not triggered automatically with each transaction.

To ensure not introducing bugs into the current transactions, it is far safer to simply insert a periodic export.

Well thanks a lot guys, for ruining a perfectly good bit of corporate cynacism with reasonable arguments. I hope you're happy....

Spffffft!

This is the internet. Don't you know that you aren't allowed to agree with our rebuttal of your cynicism? You're supposed to get all bet out of shape, start making personal attacks, and then get banned. Such a n00b.

I couldn't help it this time...next time I'll make a jerk of myself, and then ban myself in embarrasment. Still have lots of other corporate paranoia and cynacism...

But this time a memory was triggered of a friend who works for a big credit card transaction processing co, who similarly has to run huge batches everyday. I recall a similar discussion where he explained about periodic export requirements and all that stuff.
A light bulb went off in my old brain...

You are very perceptive. I bet in 10 yrs our Macs will be dock-fulls of apps bought through the app store and no more US$2,000.- sw. Just cheap catalogues of tools. App store FTW!!1
