It seems like LDAP requires strings with non-ASCII characters to be Base64 encoded. The way to tell it that a string is to be parsed as a base64 encoded string is to add an extra colon to the attribute name such that "cn: name" becomes "cn:: name" (according to this site). Now, my question is: How do I tell Ruby LDAP to do this? I could...
I need to bring an array of ruby objects in JSON. I will need to find the item in the JSON object by id, so I think it is best that the id is the key of each object. This structure makes the most sense to me: { "1": {"attr1": "val1", "attr2": "val2"}, "2": {"attr1": "val1", "attr2": "val2"}, "3": {"attr1": "val1", "a...

Background: I grew up on using Perl/Python/Ruby for sysadmin-type tasks and shell scripting. I always avoided Bash scripting whenever I needed anything programmer-ish, like functions, looping or control structures. Back then, I could pick my favorite tool for whatever the job. Problem: Now I am working in a situation where the preferr...
This question is about formatting ruby's strings. In Python, built-in data structures have a built-in to-string method, and so when a variable is printed, the string is conveniently formatted to be reflective of the data structure used. For example: >>>$ python Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15) [GCC 4.4.1] on linux2 Type...

I am working through a tutorial with the following code: <h3>New Comment</h3> <%= render :partial => @comment = Comment.new, :locals => { :button_name => "Create" } %> I believe that 'render :partial => @comment' works like 'render :partial => "comment", :object => @comment' Where does ' = Comment.new' fit in? Is it shorthand f...
