I have a string like this: "2010-01-01 12:30:00" I need that to convert to UTC from the current local time zone. I tried this, but it seems to think that the string is already UTC. "2010-01-01 12:30:00".to_datetime.in_time_zone("Central Time (US & Canada)") => Fri, 01 Jan 2010 06:30:00 CST -06:00 I am not sure where to go from her...

I am looking at this boot.rb file: http://github.com/bestbuyremix/BBYIDX/blob/master/config/boot.rb And after trying to understand it, it is as if I have learned nothing so far. Can someone detail what is going on here? I have no idea how someone could even come up with this? # Don't change this file! # Configure your app in config/...
I was interested in comparing ruby speed vs python so I took the simplest recursive calculation, namely print the fibonacci sequance. This is the python code #!/usr/bin/python2.7 def fib(n): if n == 0: return 0 elif n == 1: return 1 else: return fib(n-1)+fib(n-2) i = 0 while...
I have small problem with a simple tokenizer regex: def test_tokenizer_regex_limit string = '<p>a</p>' * 400 tokens = string.scan(/(<\s*tag:.*?\/?>)|((?:[^<]|\<(?!\s*tag:.*?\/?>))+)/) end Basically it runs through the text and gets pairs of [ matched_tag , other_text ]. Here's an example: http://rubular.com/r/f88JBjfzFh Works f...
In this usps ruby gem, how should we write the following address specs: it "should build the HTTP request" # given a hard-coded address it "should parse the XML response" # given a hard-coded response I know how to get the specs to work by breaking the standardize function up into parts, but I don't want to do that because it's unnece...

I program primarily in Ruby and C#. I'd like a code editor that can gracefully deal with incomplete code; by that I mean a code editor that doesn't protect itself from syntax errors by auto-adding matching braces and quotes, but one that pays attention to the tokens you add, and identifies that an unmatched quote doesn't mean it should s...
I am trying to format my calculator that I made in FXRuby and right now all the buttons are in one column and so I was wondering how I could use the FXMatrix class so that I can format the buttons into a much more appealing setting. Heres what the program looks like right now: require 'fox16' include Fox class Calc 50, :padRight => 5...
I'm new to ruby and was hoping someone could help me figure out how to open a file, then using gsub to find and replace by multiple conditions. Here's what I got so far but this doesn't seem to work as the 2nd replace var overrides the first: text = File.read(filepath) replace = text.gsub(/aaa/, "Replaced aaa with 111") replace = text....

I'm looking for some advice/feedback about using different languages in a layered architecture. Right now the architecture in question is an all java stack (db, middle tier, and web tier) using Spring to tie everything together. We've been tossing around the idea of using Ruby on Rails for the web tier, but I'd like to know if anyone has...
I'm working on a legacy database system where the primary key, for some strange reason, starts with 1 and is not set to AUTO INCREMENT and the next value is always max primary key + 1 (the primary key is still an integer). Furthermore, the primary key names are all custom and set by set_primary_key. Now I want to map ActiveRecord to it ...
