Re: What Version?

2010-03-14T02:16:15Z

I use 1.9.1 on my Windows 7 install without problem. Make sure to use
the installer from [link]. If you want to install
gems you'll probably also want to download and install the devkit from
the same page (it's very simple). I recommend 1.9 for new projects as
thats the newest version and 1.8.7 will eventually fall out of support.

What Version?

2010-03-14T00:23:44Z

I am kinda new to ruby and new to ruby on rails. I originally had
1.9.1 installed but that caused errors when trying to install gems and
compile them. I then installed 1.8.6 and then that has errors when
trying to use postgresql. What version is the best to install on a
windows machine where gems install and work and databases seem to work

I'd suggest looking at the Observer pattern.
Have each Ball continuously register its location (x,y) with a single
Observer object; an attempt to register to an occupied location can
be handled however you want -- throw an exception, send the Ball

Thank you for all the ideas peeps. Much appreciated, I was hoping that
there was some way to avoid iterators/loops such that a 'Ball' object
would be aware of its locatation in, for simplicities sake, '2D' space
and weather it shares it with anything else. If not then that cool but
maybe there is some undiscovered territory concept wise for me to

WSDL Interface to EPO (European Patent Office)

Hi,
I am trying to do patent searches accessing the webservice at the
European patent office

Hi, I am learning how to use WSDL but none of the Ruby Cookbook book
samples work any longer. So I created this example:
require 'soap/wsdlDriver'
wsdl='[link]
driver=SOAP::WSDLDriverFactory .new(wsdl).create_rpc_driver

Re: Is ruby-1.9 threads data safer?

The test proves nothing other than that you got what seems like a proper
sum in the end. The runtime could have made accesses to @count atomic -
or you could have been lucky (more likely).
It's actually the other way round: if the result would have been !=
20000 Ruby 1.9 could be said to behave better on threads than 1.8. The

Please provide details about the ruby implementation and version
you're using.
Also, the operating system and the version of mysql you're trying to
connect with.
With that information, we can help you out figuring out which
component needs to be replaced and guide you on the right direction.

Actually I think your question isn't really about OOP or Ruby at
all but instead is just an algorithm question related to
computer graphics or even a more general question about
combinations of things.
To bring this back to Ruby. If you have a collection of
objects and you want to consider all possible combinations

Hello,
How do I do this?
MySQL works for other languages in my PC, for PHP for example, how do
I confgiure this with ruby on rails? in which config file?
thanks!

First, look at the #each method and its siblings. These will encapsulate
the loops.
For a reasonable number of balls, you could use an array to keep track
of all the balls, then something like:
intersects_with = []
balls.each do | a_ball |
if my_ball.intersect( a_ball )
intersects_with << a_ball

Yes, it is rented, pretty much all software is. By law you own only
software you have written yourself or some software which has somebody
written from scratch for you and transferred the copyright ownership

Re: Newbie Help : Object

You could set an array of n "Ball"s, check one against each other
element of the array then pop it out and repeat with remaining elements.
So the amount of intersect() methods you will call will be
\sum_{k=1}^{n-1} k instead of (n-1)*(n). Feel free to correct me if i'm
wrong.
