Gems slowing down Rails test startup, can I selectively disable these?
I have a terrible Rails test startup time. When running a single functional test that may take 2 seconds to run, the total time from execution to returning to the command line could be up to 10-15 seconds. There are two gems I know are definitely getting in the way. A Facebook and Flickr gem (Facebooker, Flickraw). Facebooker will al...

I have user input strings specifying the cost of an event (eg: "$4 for non-members"). I am trying to parse out the upper (and lower) bound of the cost (in the example, upper == lower == 4.00). Suppose that a given string cannot be parsed (maybe it's blank). In this case, I want to be able to store in the database that the maximum cost ...
Why is Ruby BigDecimal returning a weird value?
Hi, I am writing code that will deal with currencies, charges, etc.. I am going to use the BigDecimal class for math & storage. We ran into something weird with it, however. Using this statement: 1876.8 == BigDecimal('1876.8') it returns false. If I run those values through a formatting string "%.13f" I get: "%.20f" % 1876.8 => ...

Using Dictionary.app’s thesaurus function programmatically on OSX (preferably via Ruby)
I need to write a Ruby method that takes a word, runs it through OS 10.5’s Dictionary.app’s thesaurus function, and returns alternative words. If the Ruby method ends up calling the command-line, that’s fine; I just need to be able to do it programmatically from Ruby. After looking through Ruby OSA, I realize that the Dictionary is acc...
Convincing others of Ruby over Python and PHP
G'day folks. I'm trying to introduce Ruby at work, and a few people are interested. However, I've been asked to present the benefits of Ruby over Python and PHP. I've broken this down into 2 parts: 1) show Python and Ruby's advantages over PHP; 2) show Ruby's advantages over Python. The first is easy. I'll explain things like: Everyt...

CSS/HSS Parser in Treetop and Nested Stylesheet Rules
I'm new to Treetop and attempting to write a CSS/HSS parser. HSS augments the basic functionality of CSS with nested styles, variables and a kind of mixin functionality. I'm pretty close - the parser can handle CSS - but I fall down when it comes to implementing a style within a style. e.g: #rule #one { #two { color: red; } c...
After you download an open-source Rails project, do you have to db:migrate?
This is probably a stupidly easy question for a Rails person but is causing me no end of confusion. I downloaded several open source Rails projects but am not able to run them. Usually, are you supposed to do a db:migrate before you try to run a Rails project? I thought they were supposed to just run. ...
How can I collapse this very repetitive Ruby/Rails code?
