Hi, I have a set of data in x,y coordinates across the range of -5 to 5 in each dimension. I would like to obtain the frequency distribution of the different points, and then graph them so you can see which of the points are the most frequently occurring. This would seem to be easy in Matlab, which has the hist3 command for doing frequency distributions/histograms in 3 dimensions. However,

samba 2.2.5 We use an NT PDC for password authentication and an NT WINS server. Both of those systems are on a different subnet. I have setup remote announce = <PDC subnet broadcast< and remote browse sync = <WINS server IP> Do I have to setup the SAMBA server as a master browser?

Upon further investigation "iax2 show channels" indicates that the codec is "unknown" The provider confirmed that they are set for ulaw and so am I.

I have a model that represents a Player, and within that there is a method that calculates wins and losses for that player based on a how they did in databases that are in the DB. When this calculation is over it is supposed to show a summary of the calculation. When testing it on my local machine using Webrick it works fine, but when I put it on my web server, after the calculation is done

I have a model using acts_as_tree which is working fine. Being new to Ruby I''m don''t know what enumerator is best to use for traversing a tree by depth. I can write one, but before I do I wanted to know if there is there an enumerator for traversing trees available that the community recommends? Thank you, Jose -- Posted via http://www.ruby-forum.com/.

Using acts_as_tree, is it possible to get information of the depth a tree leaf in relation to the root? Or is available to derive information to save in the way "position" can be derived and saved for acts_as_list. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I''ve got a model, "category" and another model "subcategory." Each subcategory belongs_to a category, and a category has_many subcategories. What I need to do is set it up so that I can search Category and Subcategory with one .find call. So: Category.find(:all, <etc) will find categories and subcategories. Now, I believe this can be done by making

Hello there! This is my first post! ;) I''m starting on ruby on rails, so I have many doubts about it! I''m trying to create a system that uses categories/subcategories.

Hi, I''m starting to build a simple (?!) FAQ system, and I''d like some advice on setting up the model relationships. I was going to go with a simple system of a Category table and a FAQ table (holding questions and answers) - where one FAQ belongs to one category. That''s all nice - a simple has_many / belongs_to relationship. Then I decided to add another level - Area.

My database is set up as Categories > Things associated by category_id and has_many and belongs_to. How would I go about listing all the categories and under each Category is it''s children? Is there an easy rails way to do this - preferably without using acts as tree? Any help is appreciated - thanks! -- Posted via http://www.ruby-forum.com/.

The hope is that those asking SIP or H323 questions could get help from the various supporters while the main list can deal
