<p>No errors, but the object value doesn't update either.</p>
| <p>What element is "myDOMObject"? If it's a text input, your code should be working fine. If it's something else, use <code>$("#myDOMObject").text("some text");</code></p>
| <p>If you have a DOM object, you can simply do this:</p>
<pre><code>jQuery(your_dom_object).text('Hello World!');
</code></pre>
<p>But, since you use jQuery anyway, I think you should just do</p>
<pre><code>$('#the_id_of_your_dom_object').text('Hello World');

<p>I just received my E3D v6 hotend and I am installing it on the open source design of a Prusa i3. How do I clean my hotend after each print and after using different filaments?</p>
| <p>Usually there is no need to clean the hotend, as filament sticks well to itself rather than to the inside of the hotend. If there are remains - the simplest way to clean it up is to extrude 5-10 cm of new filament, which will gather all remainings clean the hotend.</p>

<p>I'm trying to parse dates using the user's date preferences</p>
<pre><code>[NSDateFormatter setDefaultFormatterBehavior:NSDateFormatterBehavior10_4];
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateStyle:NSDateFormatterShortStyle];
NSDate *date = [ dateFormatter ... | <blockquote>
<p>It looks like the NSDateFormatter is insensitive to the change of regions.</p>
</blockquote>
<p>No, it is using the locale in both directions.</p>
<p>You can see how the formatter interpreted the date by looking at the date's description (the first <code>%@</code> in your <code>NSLog</code> format).... | <p>This looks correct. In the first output sample, the formatted date string is 7/4/200. In the second, it is 07/04/2008. </p>
<p>What difference were you expecting? </p>
<p>If you did not change your format preferences for the United Kingdom preferred date format, I believe it defaults to MM/DD/YYYY with leading... | 32,743 |
<p>How do I list the symbols being exported from a .so file? If possible, I'd also like to know their source (e.g. if they are pulled in from a static library).</p>
<p>I'm using gcc 4.0.2, if that makes a difference.</p>
| <p>The standard tool for listing symbols is <code>nm</code>, you can use it simply like this:</p>
<pre><code>nm -gD yourLib.so
</code></pre>
<p>If you want to see symbols of a C++ library, add the "-C" option which demangle the symbols (it's far more readable demangled).</p>
<pre><code>nm -gDC yourLib.so
</code></pr... | <p>If you just want to know if there are symbols <em>present</em> you can use</p>
<pre><code>objdump -h /path/to/object
</code></pre>
<p>or to list the debug info</p>
<pre><code>objdump -g /path/to/object
</code></pre>

<p>We have a REST API which clients routinely POST and PUT data to. When they do this, sometimes they POST data which results in no change on our system. The POSTs and PUTs are well-formed, but they data they're sending is identical to the data in our database. When this happens, I've just found out that we're retu... | <p>I think it's perfectly fine to return a 200 OK in that case, the data was correctly processed and the server did what it had to.
