I'm writing a DSL in Ruby to control an Arduino project I'm working on; Bardino. It's a bar monkey that will be software controlled to serve drinks. The Arduino takes commands via the serial port to tell the Arduino what pumps to turn on and for how long. It currently reads a recipe (see below) and prints it back out. The code for se...

Premise: Usually during preparation of a new Ruby on Rails App, I draw out models and relations regarding user navigations. Usually I hit a place where I need to ask myself, whether or not I should go beyond the usual "rule of thumb" of nesting no more 1 level deep. Sometimes I feel the need to nest, rather than creating another namespac...

In the installation documentation to RoR it mentions that there are many limitations to running Ruby on Rails on Windows, and in some cases, whole libraries do not work. How bad are these limitations, should I always default to Linux to code / run RoR, and is Iron Ruby expected to fix these limitations or are they core to the OS itself?...
I want to display dates in the format: short day of week, short month, day of month without leading zero but including "th", "st", "nd", or "rd" suffix. For example, the day this question was asked would display "Thu Oct 2nd". I'm using Ruby 1.8.7, and Time.strftime just doesn't seem to do this. I'd prefer a standard library if one ex...

I wonder what's the best deployment directory for Rails apps? Some developers use directories such as /u/apps/#{appname}. Are there any advantages when using /u/apps/#{appname} instead of /var/www/#{appname} or other OS default directories? Obviously I want to pick the directory with the best security properties and the least friction f...
Hi, I'm trying to understand the best way to get the connection to my databases. At the moment I've got a method wich parses the url (depending on the url called the application has to connect to a different database, like customer1.xxx.com will connect to the customer1 database) and calls ActiveRecord::Base.establish_connection(conn...
So I want to start using RSpec stories, but I am not sure where writing controller, model and view specs fit in. For example, you have the story "Logging in" with "User provides wrong password" scenario, don't you end up testing the same stuff than controller/model specs (response.should render..., user.should be_nil, etc.) So my ques...
I have an application in which attr_accessor is being used to keep temporary data for a model which will be passed to a rake task. Seeing there is not a database field for these attributes and they are not being calculated from database data, will the attr_accessor data persist and be available to the rake task? What happens if I need ...
I need to do some communications over a serial port in Ruby. From my research, it appears that there aren't many modern libraries for serial communications and the newest material I can find is from 2006. Are there any gems that I'm not aware of? I ultimately need to maintain communications with a serial device attached to USB (I can ...

When dropping the use of rspec and rspec-rails plugins and switching to the gem versions instead, is there anything extra I have to change in spec_helper.rb or something to make the specs in my app see the change? I can no longer get my specs to run successfully anymore after deleting the plugins and installing the gems (1.1.8). More...
