Make a URL-encoded POST request using `http.NewRequest(…)`
...t to make a POST request to an API sending my data as a application/x-www-form-urlencoded content type. Due to the fact that I need to manage the request headers, I'm using the http.NewRequest(method, urlStr string, body io.Reader) method to create a request. For this POST request I append my da...
Struggling with NSNumberFormatter in Swift for currency
... enter both pence and pounds from separate text fields and they need to be formatted together with currency symbols. I have this working fine at the moment but would like to make it localised as currently it only works with GBP. I have been struggling to covert NSNumberFormatter examples from Object...
Functional programming - is immutability expensive? [closed]
...sort is not by definition in-place). It requires additional storage in the form of stack space for the recursive step, which is in the order of O(log n) in the best case, but O(n) in the worst case.
Implementing a functional variant of quicksort that operates on arrays defeats the purpose. Arrays ar...
Python 3.x rounding behavior
...one method of rounding in common use. IEEE 754, the international standard for floating-point math, defines five different rounding methods (the one used by Python 3.0 is the default). And there are others.
This behavior is not as widely known as it ought to be. AppleScript was, if I remember correc...
Difference between private, public, and protected inheritance
...
This is just another case that illustrates how, for the most part, inheriting from SomeBase is just like a hardcoded way to compose-in an anonymous member of type SomeBase. This, like any other member, has an access specifier, which exerts the same control on external acce...

For instance, quoting the example given on the (now vanished) article Static variables in Javascript:

// Check to see if the counter has been initialized
if ( typeof countMyself.counter == 'u...
Resharper- Find all unused classes
...he "Inspection results" tool window you can group by "Issue type" and look for "Type or type member is never used" to get all unused classes (and many more unused symbols).
A second option (after enabling "Analyze Errors In Solution") is to go to any unused class, hit Alt+Enter, select "Options for...
What's the easiest way to escape HTML in Python?
...s:
< to &lt;
> to &gt;
& to &amp;
That is enough for all HTML.
EDIT: If you have non-ascii chars you also want to escape, for inclusion in another encoded document that uses a different encoding, like Craig says, just use:
data.encode('ascii', 'xmlcharrefreplace')
Don't...
Broken references in Virtualenvs
...rtual-env
It's probably best to check what links will be deleted first before deleting them:
find ~/.virtualenvs/my-virtual-env/ -type l
In my opinion, it's even better to only delete broken symlinks. You can do this using GNU find:
gfind ~/.virtualenvs/my-virtual-env/ -type l -xtype l -delete...
JComboBox Selection Change Listener?
...
combo.addActionListener (new ActionListener () {
public void actionPerformed(ActionEvent e) {
doSomething();
}
});
@John Calsbeek rightly points out that addItemListener() will work, too. You may get 2 ItemEvents, though, one for the deselection of the previously selected item, a...
