debug SystemStackError in ruby 1.9

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

Upload iOS application for clients on their iTunes Connect account.

Obviously, the simplest solution would be for the client to share their account details or add us as ‘team admin’, but that is not what this is about.

  1. [Add us to your iOS Developer Program as ‘team member’.][1]
  2. [Create a ‘Distribution Certificate’, if you haven’t got one already.][2]
  3. [Create a ‘App Store Distribution Provisioning Profile’.][3]
  4. [Export the ‘Distribution Certificate’ assets and send the export and password to us.][4] (For security sake, it’s a good idea to send us the password via other means than the exported certificate. E.g. by phone/SMS.)

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Notes/Patterns for Refactoring Code

Intention Revealing Methods

Intention revealing method is simple and yet I see it frequently slip through programmers' code. Developers don't like lengthy methods, or find it inconvenient to read through chubby if-else branches, and if they are nice enough they'll leave comments like those.

If we change spaces by underscores in the comments, delete the comment characters, and define the resulting methods in the same file (as private helpers for example), we get code that explains itself, instead of through verbose long methods, or human code comments which get stale.

Intention revealing methods is the most basic, no brain-teaser, easiest rule that I know. Combine it with Sandi Metz's rule of a maximum of 5 lines per method and you'll get simple code that explains itself, that is a pleasure to read, improving communication and productivity of the team (even when it's only yourself).
