This is how I debug SystemStackError when there is no stack trace.

My first attempt was:

begin
  a_method_that_causes_infinite_recursion_in_a_not_obvious_way
rescue SystemStackError
  puts caller
end

class DatabaseBackupJob
  def self.perform(id, foo, bar)
    # do backup work
  rescue Resque::TermException
    # write failure to database

    # re-enqueue the job so the job won't be lost when scaling down.
    Resque.enqueue(DatabaseBackupJob, id, foo, bar)

Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:

How to Make a Classic Mojito

Drink recipes are subjective. Experimentation is a lot of fun, and quite frankly encouraged. However, you really should know what the fuck you're doing before you go all willy nilly throwing everything in your kitchen into a glass and calling it a cocktail. This is the classic Mojito. It's damn fine on it's own. In fact, this is the only way I drink them. Once you've mastered this technique, feel free to experiment with other stuff like mangoes or pineapple or whatever. Just, please, don't call your franken-drink a Mojito.

Why I love zsh (and hate being forced to use bash)

• Smarter completion. A few examples:
• context sensitive -- if you have file "name1" and directory "name2", "cd nam<TAB>" completes to "name2/"
• "tar xf <TAB>" completes to tarballs only. "unrar x <TAB>" completes to RARs only. etc.
• rsync / scp completion: "rsync host:anything/<TAB>" shows you files on host under anything/
• also works with rsync:// URLs
• SSH host completion from ~/.ssh/config & ~/.ssh/known_hosts
• lots of other smart completions: Rake tasks, git commands & SHAs, dpkg packages, dash-options for most commands, etc etc.
