mms2r 1.1.8 Released
mms2r version 1.1.8 has been released!
- <http://mms2r.rubyforge.org/>
DESCRIPTION:
MMS2R is a library that decodes the parts of an MMS message to disk while
stripping out advertising injected by the cellphone carriers. MMS messages are
multipart email and the carriers often inject branding into these messages. Use
MMS2R if you want to get at the real user generated content from a MMS without
having to deal with the cruft from the carriers.
If MMS2R is not aware of a particular carrier no extra processing is done
to the MMS other than decoding and consolidating its media.
Contact the author to add additional carriers to be processed by the
library. Suggestions and patches appreciated and welcomed!

Changes:
1.1.8 / 2007-09-08 (James Grishnack – Head of Behemoth Productions, producer
of Blood Ocean)

helpful Ruby idioms (to me)
Before coming to Ruby I had spent a lot of time coding Java and some C/C++ . Like any programmer I spend a lot of time working with data structures (and now blocks in Ruby). I would often fall back to idioms concerning data structure size in those legacy languages but in Ruby they are bad habits.
The Enumerable module that is mixed in to Array, Hash, and others is your friend. Use its idioms to tell you the state of your data structure rather raw details as in Java that imply state. For instance in Java, we test for elements in a collection with.size() (like myhash.size() == 0), but in Ruby having elements (or not) is more statefully conveyed with .any? and .empty?
Some goodies in Enumerable :
- any? – do we have any elements?
- empty? (in Array class) – are we void of elements?
- detect – return the first element that matches the criteria in the block
- select – return all the elements that match the criteria in a block
- each_with_index – enumerate over elements in the data structure AND automatically give me an index (which means I don’t have to predefine one)
And example in an irb session:
mike@butch 10001 ~$ irb
irb(main):001:0> a = ['hello', 'ruby-20', 'ruby']
=> ["hello", "ruby-20", "ruby"]
irb(main):002:0> a.detect{|v| v =~ /foo/}
=> nil
irb(main):003:0> a.detect{|v| v =~ /hello/}
=> "hello"
irb(main):004:0> a.detect{|v| v =~ /ruby/}
=> "ruby-20"
irb(main):005:0> a.select{|v| v =~ /ruby/}
=> ["ruby-20", "ruby"]
irb(main):006:0> a.empty?
=> false
irb(main):007:0> a.any?
=> true
irb(main):008:0> a.each_with_index{|v,i| puts "index: #{i}, val #{v}"}
index: 0, val hello
index: 1, val ruby-20
index: 2, val ruby
=> ["hello", "ruby-20", "ruby"]

Apache2 Redirect To Feedburner
This is how I’m doing a 302 redirect to Feedburner from my Apache2 virtual host settings for this blog. Its only for the main articles syndication in RSS and Atom . Everyone is redirected to Feedburner except for their web crawling bot. I’m doing this so people can see Feedburner’s shiny widget ( ) in the sidebar showing that only 1 or 2 people subscribe to my blog.
I put the following in between the RewriteEngine On statement and the static maintenance statement RewriteCond %{DOCUMENT_ROOT}/system/maintenance.html -f covered in this post describing an Apache vhosts setup for a Rails app
# 302 temporary, 301 permanent
RewriteCond %{HTTP_USER_AGENT} !^FeedBurner/.*
RewriteRule ^/xml/rss20/feed.xml$ http://feeds.feedburner.com/mondragon/PQVR [R=302,L]
RewriteRule ^/xml/atom/feed.xml$ http://feeds.feedburner.com/mondragon/PQVR [R=302,L]

Rails Models in a Namespace
If you are starting to get a cluttered model space in your Rails application
you should consider placing your models in a namespace. As an example I’m
going to go through a Rails application I’m calling Recipes. If my
models were starting to have the namespace implied in the class names such as
AppleFruit in app/models/apple_fruit.rb then that’s starting to smell like
rotten apples. A better namespace would be Fruit::Apple in app/models/fruit/apple.rb
This is what we’ll be modeling. Fruits of Apples and Oranges via single table
inheritance. And Vegetables of Potatoes and Carrots through single table
inheritance.
We’ll have Ingredients that belong to Fruit, Vegetables, and Recipes.
Ingredients are a limited kind of join model going from the recipe through
to the kind of ingredient (i.e. fruit or vegetable). Ingredients are a true
join model from the fruit or vegetables back to their associated recipes.
The Ingredient is polymorphic because Fruits and Vegetables are different kinds of
objects.
Finally Recipes are another single table inheritance model but by
convention they will only have ingredients, they won’t be associated
to the kinds of ingredients through the polymorphic Ingredient class.
To access the specific kinds of ingredients from the recipe’s perspective
you must access the collection of ingredients and then program the desired
behavior to access the kinds of ingredients in your application logic.
Here’s a graph of the models we are designing (click for bigger picture):
The graph was made with Railroad which uses
Graphiz to generate the graphs.
All of the source for this example as available at the following Subversion
code repository
svn checkout http://svn.mondragon.cc/svn/recipes/trunk/ recipes
