I'm developing an app where I use performSelectorInBackground to do some sync task in the background. In my code I want to be able to detect whether I'm runing in a background process. This way I can prevent alert messages which might otherwise show up. Thanks for your help! Markus ...
I need to perform a task every 5 seconds, but only when users are using the application. As for now, I use cron that works every minute and activates a task that repeats itself every 5 seconds with sleeps between, for a minute. However, it works also when the application isn't being used. Is there a gem that will do this kind of thing?...

I'll guess that there's a way to call a function and prevent it from returning it's value to thereby accomplishing this? Pseudo-code: function myFunction() { startProcess(); return $someth...
I'm trying to get a better grasp of the inner workings of background jobs and how they improve performance. I understand that the goal is to have the application return a response to the user as fast as it can, so you don't want to, say, parse a huge feed that would take 10 seconds because it would prevent the application from being abl...

I have an asp.net application with a background thread. The thread starts when the application starts and it is gracefully stopped when the application ends. I am running the website on a shared host. Unfortunately sometimes the application does not trigger the Application_End event when it ends. I would think that the threads would be k...

I have a python webapp which accepts some data via POST. The method which is called can take a while to complete (30-60s), so I would like to "background" the method so I can respond to the user with a "processing" message. The data is quite sensitive, so I'd prefer not to use any queue-based solutions. I also want to ensure that the b...

I've written an iPhone app to display available bandwidth for my satellite modem, but I'm interested in allowing the timer to continue to fire in the background (though with much greater time between ticks) and display UILocalNotifications during events such as reaching a 20% remaining limit.
