Read binary file as string in Ruby
I need an easy way to take a tar file and convert it into a string (and vice versa). Is there a way to do this in Ruby? My best attempt was this:

What is the best way to get all the divisors of a number?

def divisorGenerator(n):
large_divisors = []
for i in xrange(1, int(math.sqrt(n) + 1)):
if n % i == 0:
yield i
if i*i != n:
large_divisors.append(n / i)
for divisor in reversed(large_divisors):

What a hack. If they invent a new syntax for label pointers, they should invent a new type for it as well instead of using void*.

WebView and HTML5
...
I answer this topic just in case someone read it and is interested on the result.
It is possible to view a video element (video html5 tag) within a WebView, but I must say I had to deal with it for few days. These are the steps I had to follow so far:

Get the client's IP address in socket.io
...ket.handshake.headers["x-real-port"];

var ip = socket.conn.remoteAddress;
works with socket.io version 1.4.6 for me.

String vs. StringBuilder
...using strings and the plus operator. This is because (like Java, as Eric points out), it internally uses StringBuilder automatically (Actually, it uses a primitive that StringBuilder also uses)
However, if what you are doing is closer to:
string a,b,c,d;
a = a + b;
a = a + c;
a = a + d;
Then ...
What is the best scripting language to embed in a C# desktop application? [closed]

Btw - to enable C# script support you can either integrate C# script library inside, or make C# script compilation on your own. I have done similar lightweight C# script compiler into my own project in here: sourceforge.net/p/syncproj/code/HEAD/tree/CsScript.cs C# script ...
Should I use px or rem value units in my CSS? [closed]
...e of rem is 10px which means any value you might have written in px can be converted directly to rem by bumping a decimal place.
padding: 20px;

Understanding slice notation
...ve:
a[start:stop:step] # start through not past stop, by step
The key point to remember is that the :stop value represents the first value that is not in the selected slice. So, the difference between stop and start is the number of elements selected (if step is 1, the default).
