I'm just starting with Ruby and I personally find the following to be a violation of the "principle of least surprise". And that is, quoting from the documentation, that uniq! "removes duplicate elements from self. Returns nil if no changes are made (that is, no duplicates are found)." Can anybody explain this, which seems completely c...
While declaring array we can use brackets any side of the identifier but in the case: int[] k,i; and int k[],i; It will be considered in two different ways. That is first one creates two arrays k and i. that second one creates an array k and a normal variable i. What is this behavior? EDIT: in java usually we prefer first type of...
I need to get a grip on arrays and XML data but I'm having trouble understanding how to turn xml data into useful data. I was hoping these forums might provide some insight. I load my XML with this code: //set values for XML data file private var XML_URL:String = "http://www.mysite.com/media/locXML.xml"; private var locXML:XML = new XM...

So for example, Area ID 153 might have 20 coordinates and area ID 77 might have 11 coordinates. I wish to save these in a 2-D array indexed by the area ID, and where each coordinate pa...
I have a customized .profile that I use in ksh and below is a function that I created to skip back and forth from directories with overly complicated or long names. As you can see, the pathnames are stored in an array (BOOKMARKS[]) to keep track of them and reference them at a later time. I want to be able to delete certain values from ...
Hello, I generate a list of one dimensional numpy arrays in a loop and later convert this list to a 2d numpy array. I would've preallocated a 2d numpy array if i knew the number of items ahead of time, but I don't, therefore I put everything in a list. The mock up is below: >>> list_of_arrays = map(lambda x: x*ones(2), range(5)) >>> l...
I'm just wondering if Prototype's helper functions Array.compact() and Array.without() filter for multidimensional arrays. It doesn't look like it, and if so, was there a reason for this or is there another helper function in Prototype that does this? ...
I have an array of street names sorted alphabetically that I have gathered from a web service. This array exists on the server side. On the client side, a user starts typing the name of the street he lives on and AJAX is used to return a list of the closest match to the partial street name, plus the next 9 street names in the array (the...

Apologies in advance if this is a silly question but I'm wondering which might be faster/better in the following simplified scenario... I've got registered users (in a users table) and I've got countries (in a countries table) roughly as follows: USERS TABLE: user_id (PK, INT) | country_id (FK, TINYINT) | other user-related fields... ...
I'm trying to find the best approach to filtering a list with C# (3.5) but I can't seem to find any examples that are similar to my situation. I'm open to using lambdas or linq. The thing that is unique compared to most of the examples that I've found, is that my list items each have child arrays for example... var employees= new Lis...

I'm in a little bit of a bind. I'm working with a legacy system that contains a bunch of delimited strings which I need to parse. Unfortunately, the strings need to be ordered based on the first part of the string. The array looks something like array[0] = "10|JohnSmith|82"; array[1] = "1|MaryJane|62"; array[2] = "3|TomJones|77"; S...
I'd like to be able to query an array (multi and single dimensional ) with something like SQL. Is there a way to do this? It just seems extraordinarily wasteful to step through it one record at a time. ...
I have a few functions that should return an array, to have it merged with another array. However, sometimes there's nothing to return. What's the best scenario here? Return an empty array and merge that with the full one OR Return null, store the return in a variable, check that variable and THEN merge it if needed. I'm asking this...
