I am using seeds.rb to populate some State model reference data: State.create :name => 'Alabama', :abbreviation => 'AL' State.create :name => 'Alaska', :abbreviation => 'AK' # ... Although I am not using state fixtures (since it's seed data to begin with, I think it wouldn't be DRY to have to duplicate this purely for tests), the Rail...
Sorry for this question, apparently all my googling and api searching skills must be failing me. I've written a web crawler in ruby and I'm using Nokogiri::HTML to parse the page. I need to print the page out and while messing around in IRB I noticed a pretty_print method. However it takes a parameter and I can't figure out what it wants...

I have a ruby hash: VALS = { :one => "One", :two => "Two" } and an Array: array2 = ["hello", "world", "One"] Question: How can I populate a new array1 so that it only pulls in any values in array2 that match exactly the values in VALS? For example, I have tried: array2.each_with_index do |e,i| array1 << e if VALS[i] ~= e end Alon...
I can't get the Ruby interpreter to run on either of my Macs (one MacBook and one MacBook Pro, both running Snow Leopard). When I run it, by typing ruby in Terminal, nothing happens. It just sits there. I can kill it by pressing Ctrl+C, but that's it. I know the Ruby process is running, since I can see it in Activity Monitor, and running...

I'm working with UTF-8 strings. I need to get a slice using byte-based indexes, not char-based. I found references on the web to String#subseq, which is supposed to be like String#[], but for bytes. Alas, it seems not to have made it to 1.9.1. Now, why would I want to do that? There's a chance I'll end up with an invalid string should ...

I have a string (authenticated, trusted, etc.) containing source code intended to run within a Ruby loop, quickly. In Python, I would compile the string into an abstract syntax tree and eval() or exec() it later: # Python 3 example given_code = 'n % 2 == 1' pred = compile(given_code, '<given>', 'eval') print("Passed:", [n for n in rang...
I'm trying to convert programatically PDF to HTML. So far I've been using pdftohtml but our users are not happy with the results. Here's what I need : I'm using Ruby on Rails, but any tool working on Unix would work as I can call it from the command line. But of course a nice gem or plugin would be perfect. I'd prefer it to be open s...

What approach should I take to develop software to block traffic at the desktop level (windows) to sites based on their domain name. Messing with a host file was easy, but the browser seems to have too long of a delay before it recognizes changes in the host file.
