<p>I know <code>class foo(object)</code> is an old school way of defining a class. But I would like to understand in more detail the difference between these two.</p>
| <p>Prior to python 2.2 there were essentially two different types of class: Those defined by C extensions and C coded builtins (types) and those defined by python class statements (classes). This led to problems when you wanted to mix python-types and builtin types. The most common reason for this is subclassing.

<p>I have huge 3D arrays of numbers in my .NET application. I need to convert them to a 1D array to pass it to a COM library. Is there a way to convert the array without making a copy of all the data?</p>
<p>I can do the conversion like this, but then I use twice the ammount of memory which is an issue in my applicati... | <p>I don't believe the way C# stores that data in memory would make it feasible the same way a simple cast in C would. Why not use a 1d array to begin with and perhaps make a class for the type so you can access it in your program as if it were a 3d array?</p>
| <p>Without knowing details of your COM library, I'd look into creating a facade class in .Net and exposing it to COM, if necessary.<br>
Your facade would take a double[,,] and have an indexer that will map from [] to [,,].</p>

<p>I have some static images in a folder on my IIS 6-based website that I want to be downloaded as little as possible (to preserve bandwidth). I've set the Content Expiration to expire after 30 days. Is there anything else I can do in IIS to try to maximize the caching by browsers, proxy, and gateway caches?</p>

It's a PHP/mySQL versioning tool which works with any database type and is fairly simple to learn.</p>

<p>In my cross-platform architecture, I would like to act on a context menu click (right button click) during a mouse click event. In Cocoa, can you detect that the user either Ctrl-Clicked or double-tapped on touchpad (right-click equivalent) DURING the mouseDown event? I am aware of NSView's menuForEvent but do not... | <p>If you're using AppKit, and you want to detect a right-click in your view, you should override <code>-[NSResponder rightMouseDown:]</code>.</p>
| <p>Swift version:</p>
<pre><code>override func mouseDown(theEvent: NSEvent) {
if theEvent.modifierFlags.contains(.ControlKeyMask) {
return rightMouseDown(theEvent)
}
super.mouseDown(theEvent)
}
</code></pre>

<pre><code>1 Dim x as Integer? = Nothing
2 If x = Nothing Then
3 'this is what I think will happen
4 Else

<p>The proper way to write that is "If x Is Nothing".</p>
