I found what I thought should work perfectly at http://stackoverflow.com/questions/517219?tab=oldest#tab-top but, it did not work for me. I have Ruby 1.9.1 installed on Windows and, when I try the example "is_port_open" test, it does not work. The socket call still takes around 20 seconds to timeout no matter what value I set for the ti...
In Ruby, can I do something C-like, like this (with my made-up operator '&'): a = [1,2,3,4] and b = &a[2], b => [3,4], and if I set b[0] = 99, a => [1,2,-9,4]? If the elements of an array are integers, does Ruby necessary store them consecutively in a contiguous part of memory? I'm guessing "no", that only addresses are stored, intege...
I am having two structures similar to the one below. [1 => [{'pc'=>1,'id'=>0},{'pc'=>4,'id'=>0},{'pc'=>2,'id'=>1]] But both of them need not contain the inside array in the exact same order. How to compare in such case? ...

I want to offer the current date to the user when a new record is created and I want to allow him to edit the offered date. For example I write a bug tracking system and I have a date_of_detection field. 99% of the time it is good if it is the current date, but for the sake of the 1% the user should be allowed to edit it and set any earl...

I have the following code in one of my personal projects: def allocate(var, value) # Allocate the variable to the next available spot. @storage.each do |mem_loc| if mem_loc.free? mem_loc.set(var, value) # Set it then break out of the loop. break end end end Each item in the storage array is an object that resp...

So Candy is a really simple library for interacting with Mongo in Ruby. My poor SQL brain is having a tough time figuring out how I should map out this problem: There are users, there are things. Each thing was made by one user, but should be accessible to a subset of all users (specified within the thing). Leaving the specification of...

I have been playing around with Rake and Albacore, to see if I can replace our existing MSBuild script that deploys software with something that isn't XML. I have a task that will change the debug value inside a web.config to false. The task takes the directory of the web.config as an argument, but I can't quite figure out the syntax n...

Ruby has an excellent mechanize and XML parsing library but the spreadsheet support is very poor. PHP has excellent spreadsheet and HTML parsing library but it does not have an equivalent of WWW:Mechanize. Python ...
If the following code in Ruby can print out "browser type" and "count" individually as 2 separate lists, can REXML select each entry and then print out entry['title'].text and entry['dxp:metric'].attr('value') /* not using exact syntax */ on the same line as one list? require 'rexml/document' include REXML xmlfile = File.new("data....
Ok, I'm not trying to start a flame war here, and I know the argument between static and dynamic languages has been hashed out many times, including here. But I have a very practical question that hopefully someone here can shed some light on. Sorry for the length, but this is not a simple question with probably not a simple answer. Rub...

I want to add an automatic embedding feature when a YouTube URL is used (http://www.youtube.com/watch?v=VID, where VID is the video's ID). For this, I need to check if the given URL, stored in the variable url, matches "/http:\/\/www\.youtube\.com\/watch\?v=([a-z0-9]+).*/i", then I need to strip out the VID to use it (e.g. put the VID i...
