1,770,101 | 1,770,102 | Inaccurate device orientation retuned by UIDeviceOrientationDidChangeNotification | <p>I'm listening to the UIDeviceOrientationDidChangeNotification in order to adjust my UI based on the device's orientation. </p>
<p>The problem is that the device orientation I'm getting from the notification seems inaccurate. If I start with the phone in portrait orientation and vertical (as if taking a picture with it) the orientation I get from the notification is correct. As the tilt of the phone approaches horizontal (as in laying flat on a table top) the orientation switches to landscape. This happens much before the phone is actually flat on the table. And this is without rotating the phone towards landscape at all. Is as if it had a preference for landscape. </p>
<p>When using other apps, like mail, I don't see this same behavior. It seems that mail only switches orientation once it's really sure you've gone to the new orientation.</p>
<p>Any help greatly appreciated.</p>
<p>Thanks,</p>

<p>Now, if the selected option changes, I want to change the "content" ("Foo Bar" and "Bar Baz" in the example). How can I do that with jQuery? I tried the following, but obviously, it doesn't work.</p>
<pre><code>$('#authors').change(function(){
$('#authors option[selected=selected]').html('new content');

<p>/edit: to clarify, the selector <code>'#authors option[selected=selected]'</code> works fine, it selects the correct <code>option</code> DOM element. But <code>.html('new content')</code> does nothing.</p>
<p>2nd edit: OK, this is embarrassing. I tried my code in Chrome's JavaScript console, where it didn't have any effect. After jAndy clearly demonstrated that it works in jsFiddle, I tried it in the FireBug console, and there it works. Lesson learned :-)</p>

<pre><code>$('#thetable tbody').replaceWith(newtbody);

<p>in an ajax callback. Sometimes, if the user had scrolled the page down, this operation has the understandable side effect of scrolling the page back up. But the replacement appears seamless to the user so it's a bit annoying to have to scroll back down again.

<p>Now, since I found that executing:</p>

I have published a very simple android application it's name is "Vib-e-rator PRO". It's purpose is obvious, it can be used as a masssage vibrator or as an erotic stimulator...</p>
<p>My Problem is don't have an Android Phone to test my app in real time.</p>
<p>I have been recieving mixed comments from people. A few users say its working fine. But majority of them complained that the Phone would n quit vibrating even after the closing application. </p>
<p>Later i speculated that when ever the user switched off the vibrator and quit the app it would work as expected. If any user (most of em) directly closed the application ( either through the close option provided in the app itself or by pressing the END button in the phone ) without switching off the vibrator then it would not stop vibrating.</p>
<p>So i added myvib.Cancel() (myvib is the context for Phone Vibrator) in the exit block the close option provided in my app. For the other scenario, when it is closed by pressing the END button in phone, i have no idea how to solve it... So friends please advice me what is necessary to do... The comments i have been receiving from many users of my app is really embarassing.... </p>
