Check if a value is within a range of numbers
...u're asking a question about numeric comparisons, so regular expressions really have nothing to do with the issue. You don't need "multiple if" statements to do it, either:
if (x >= 0.001 && x <= 0.009) {
// something

Calling closure assigned to object property directly
...sn't work on a StdClass.
Before PHP7, you'd have to implement the magic __call method to intercept the call and invoke the callback (which is not possible for StdClass of course, because you cannot add the __call method)
class Foo
{
public function __call($method, $args)
{
if(is_...

Using Python's os.path, how do I go up one directory?
...
os.path.abspath(os.path.join(os.path.dirname( __file__ ), '..', 'templates'))
As far as where the templates folder should go, I don't know since Django 1.4 just came out and I haven't looked at it yet. You should probably ask another question on SE to solve that issue....
\d is less efficient than [0-9]

Make a div into a link
...- if you look, they're actually proper markup.
For me the no-nos are: javascript (shouldn't be needed just for a link, and very bad SEO/accessibility); invalid HTML.
In essence it's this:
Build your panel using normal CSS techniques and valid HTML.
Somewhere in there put a link that you want to...
