In ruby, is there a way to "undefine" a variable or constant once it's been defined? In our rails environemnts, we define one of three contants to be true, depending on the environment: TESTING, DEVELOPMENT, or PRODUCTION.

I have a selection of relatives that want to buy me Christmas presents, sadly I can think of only 3 things that I really need (I'm a pretty content person). However, it occurred to me that I want to learn Ruby a little at some point and getting a Dead tree version of a Ruby book would be useful for that. As such I'm looking for suggest...

I'm an email n00b but I am working on an application that sends HTML email with Unicode characters (as my friend noted "enjoy encoding hell"). The Subject: header comes from user input and therefore may contain Unicode characters. Some mail clients (like GMail and Outlook 2007) are OK with this, but from my reading it seems the right wa...

For example if you declare a variable `foo' equals "Ted" and you declare a string "Hello, #{foo}" it interpolates to "Hello, Ted". I've not been able to figure out how to perform the magic "#{}" interpolation on data read from a file. In pse...

I'm looking to implement a state machine to manage a user moving through a series of steps over an extended period of time (weeks) with emails and then they interact with the app. I've looked at a couple of AASM plugins and forks (it seems like this plugin space has become a bit chaotic) and am curious what people would recommend. I sa...
My homepage (or welcome page) will consist of data from two models (lets call them authors and posts). I am new to rails and not sure what is the best way to accomplish this. Should I create a new controller called welcome which gathers data from the authors and posts and then display them in the welcome index view? Or should I have a w...
I've built a nice website system that caters to the needs of a small niche market. I've been selling these websites over the last year by deploying copies of the software using Capistrano to my web server. It occurs to me that the only difference in these websites is the database, the CSS file, and a small set of images used for the ind...
Is the LAMP (Linux, Apache, MySQL, PHP / Ruby / Python) stack appropriate for Enterprise use? To be clear, by "Enterprise", I mean a large or very large company, where security, robustness, availability of skill sets, Total Cost of Ownership (TCO), scalability, and availability of tools are key considerations. Said another way, a compa...
