<p>I am converting an old Makerbot Replicator 2 to Marlin Firmware and everything works. The printer heats up, auto bed levels, and starts the print. However, after a couple minutes (usually after the 1st or 2nd layer), the printer crashes and stops. It does not continue printing and I have to restart it again.

<p>The project I'm working on uses a window.onerror event handler to report user problems. I've noticed a single user that just cannot seem to load the Google Analytics script. Our site doesn't see a lot of traffic so I'm not sure how widespread this is, but so far it seems to just effect one user. </p>

<p>You don't see this error in the Firefox error console, but you can make it visible by binding an alert to the window.onerror event.

<p>How can I unset variable? For example, PHP has an <code>unset($var)</code> function.</p>
| <p>There is not really an equivalent to "unset".</p>
<p>The closest match I know is the use of the <a href="http://msdn.microsoft.com/en-us/library/xwth0h0d(VS.80).aspx" rel="noreferrer">default</a> keyword.</p>
<p>For example:</p>
<pre><code>MyType myvar = default(MyType);
string a = default(string);

<p>PowerShell is definitely in the category of dynamic languages, but would it be considered strongly typed? </p>
| <p>There is a certain amount of confusion around the terminlogy. <a href="http://eli.thegreenplace.net/2006/11/25/a-taxonomy-of-typing-systems/" rel="noreferrer">This article</a> explains a useful taxonomy of type systems.</p>
<p>PowerShell is dynamically, implicit typed:</p>
