In Observable's notifyObservers method, why does the coder use arrLocal = obs.toArray();?
Why does not coder iterate vector directly? Thanks
public void notifyObservers(Object arg) {
Object[] arrLocal;
synchronized (this) {
/* We don't want the Observer doing callbacks into
* arbitrary code while holding its own…
I have a grouped UITableView with a custom UITableViewCell class and I am adding a custom background image to each cell. However, when I do this, the cell's separator is not visible.

Is there a mature library that could enable audio input and output and work within Haskell? (A nice wrapper is fine, of course.)
I'm looking for something that can easily capture microphone input and, perhaps, play various audio files as well.

I have a Reports controller and various reports:
http://localhost/reports/main/this_month
http://localhost/reports/main/last_month
http://localhost/reports/main/this_year
I wanted http://localhost to default to http://localhost/reports/main/this_month. That is easy enough using map.root in my routes.rb.
However when I do this any links…

So I have input coming in like:
12_34 5_6_8_2 4___3 1234
and the output I need from it is:
1234, 5682, 43, 1234
I'm currently working with
r'[0-9]+[0-9_]*'.replace('_','')
which (as far as I can tell) successfully rejects any input which is not a combination of numeric digits and under-scores, where the underscore cannot be the first…

I try to index over results returned by an xpath. For example:
xpath = '//a[@id="someID"]'
can return a few results. I want to get a list of them. I thought that doing:
numOfResults = sel.get_xpath_count(xpath)
l = []
for i in range(1,numOfResults+1):
l.append(sel.get_text('(%s)[%d]'%(xpath, i)))
would work because doing…

I've just had to write a string reverse function in C# 2.0 (i.e. LINQ not available) and came up with this:
public string Reverse(string text)
{
char[] cArray = text.ToCharArray();
string reverse = String.Empty;
for (int i = cArray.Length - 1; i > -1; i--)
