I need to do a: require 'generator' Inside of a rails project, but it is not working for me on OSX, because the ruby standard library (which is located in my /usr/lib/ruby/1.8) is not in my $LOAD_PATH once rails boots. If I just run irb outside of rails it is there. Where/What do I need to config? ...
I'm looking to start using a key/value store for some side projects (mostly as a learning experience), but so many have popped up in the recent past that I've got no idea where to begin. Just listing from memory, I can think of: CouchDB MongoDB Riak Redis Tokyo Cabinet Berkeley DB Cassandra MemcacheDB And I'm sure that there are mor...
I am working on an application in which one module accesses a log (an ActiveRecord model) to increment various values at several points of the execution. The problem is that the script is likely to take several seconds, and other instances of the same script is likely to run at the same time. What I'm seeing is that while the script fin...

The idea is to have it say something like "1000*min_level" and somehow run it to calculate the skill damage. Is there any good way to do th...
Hey there, I was wondering if there is a built-in method in Ruby that allows me to convert lap times in the format of hh:mm:ss.sss to milliseconds and vice versa. Since I need to do some calculations with it, I assumed that converting to milliseconds would be the easiest way to do this. Tell me if I am wrong here :) Cheers, Chris ...
Excuse if this is a silly question, I am new to mocking. I am able to use mocha to do things like: person.expects(:first_name).returns('David') How can I mock a nested object? Say I have a Product that belongs to a Person and I want to get the first name of that person. In my app I might do it like this: product.person.first_name ...

Hi I am trying to figure out the best way to do this... Given a string s = "if someBool || x==1 && y!=22314" I'd like to use Ruby to seperate statements and boolean operators.. so I'd like to split this into ["if","someBool","||","x","==","1","&&","y","!=","22314"] I could use s.split(), but this only splits with space as delim...

Hi, I'm trying create a bot which automatically "likes" Facebook posts. Using Mechanize I can log into facebook, but unforunately the links to the like button are not understood by Mechanize - they seem to be obsfuscated by JS. The only links I see are the basics such as: <Mechanize::Page::Link "Edit friends" "http://www.facebook.co...

I have these lines in my ~/.inputrc: set editing-mode vi set keymap vi This allows me to use vi keybindings in every program that uses GNU readlines for text input. Examples: python, irb, sftp, bash, sqlite3, and so on. It makes working with a command line a breeze. Matlab doesn't use readlines, but vi keybindings would be amazing...

' now' : ' no longer'} allowed at #{position}" end def allow=(letter, position, allowed) # ... end end Writing i...
We recently began a compliance push at our company and are required to keep a full history of changes to our data which is currently managed in a Rails application. We've been given the OK to simply push something descriptive for every action to a log file, which is a fairly unobtrusive way to go. My inclination is to do something like...
