• Do autorelease methods always survive a whole method?

  - by Jan Hendrix

  Hi, If I'm correct then the releasing of the pool of autoreleased objects has something to do with the run loop.. I barely have an idea of what that 'run loop' is but my question is, is it possible that the object gets released before the end of the method is reached?

• Prevent an Activity from being killed by the OS while starting a child activity

  - by Martin Marinov

  I have a main activity which calls a child one via Intent I = new Intent(this, Child.class); startActivityForResult(I, 0); But as soon as Child becomes visible the main activity gets its onStop and immediately after that onDestroy method triggered. And as soon as I call finish() within the Child activity or press the back button, the Child activity closes and the home screen shows (instead of the main activity). How can I prevent the main activity from being destroyed? :\

• Rails - good tool to create a scheduled background process which will regularly retrieve messages fr

  - by adam

  Background Job gets mentioned a lot but all the tutorials I've seen seem to indicate that its for queuing jobs which are created by some external event such as a user clicking "Send mail". But what about when you have code that needs to scheduled to run every 30 seconds to listen for new messages from twitter? Normally rake is recommended for set in stone schedules but it inst so efficient for frequent jobs as it has to to load the entire rails app each time. Can anyone recommend anything for this situation?

• jQuery AJAX requests with Rails 3

  - by elsurudo

  I'm trying to do a manual jQuery AJAX request the following way: $("#user_plan_id").change(function() { $("#plan_container").load('/plans/' + this.value); }); I have the "rails.js" file included in my header, and a "<%= csrf_meta_tag %". I see from my log that the request IS getting to the server (although without the authenticity token... does rails.js even do this?), but the response is a 302 (Found) rather than 200, and no data actually gets rendered. Any ideas?

• Naming my application in android

  - by Sephy

  Hi, I think i'm getting senile because I was convinced that to give a name to your application, you had to fill this part of the manifest : <application android:icon="@drawable/icon" android:label="MyApplicationName"> However for a reason I don't understand, my application gets the name of my first activity, in which I load data, henceforce, It is called "Loading"...(defined as follows in the manifest) <activity android:name="AccueilSplash" android:label="Loading"> Any idea why that is?

• Can this jQuery code snippet be shortened?

  - by David Vidmar

  I have just stared using jQuery and although following code gets the job done, I have a feeling that it can be shortened. var accountAddress = $(document.createElement("input")).addClass("readOnly").attr("contentEditable", "false").attr("id", "d_accountAddress"); $("#customerid_c").next().next().next().append(accountAddress); If it is not clear - what I'm doing is creating new input tag, assigning class and making it readonly, then positioning new input two TD's to the right of some known text.

• How to get JMeter to request gzipped content?

  - by Bill Paetzke

  My website serves gzipped content. I verified with Firebug and YSlow. However, JMeter does not request the gzipped content. Therefore, it gets all uncompressed content. As a result, my test cases take much longer (6-10x longer) than they do in reality. How can I make JMeter request gzipped content from a website? FYI, I am using the latest stable build: JMeter 2.3.4 r785646.

• Remove stateful EJB bean in client

  - by palto

  I'm currently learning EJB and as I understand when client gets a stateful session bean the server keeps it in memory(or passivates it) until the client removes the bean. Pretty simple, except nowhere I have seen any examples of how the client can actually remove the bean. How do you do that other than shutting down your client application? Or do I just have to implement a reset method in all my stateful beans if I want to start over?

  On a Windows PC, is there a way to read the raw bytes from an SD card attached trough a USB card reader? The SD card gets written from an embedded system using no file system at all, so I can't use standard file access routines.
