I remember years ago when I was looking solution for running dropbox on terminal, it is not stable yet. Now, finally there is way for that.

After that, just follow the appear generate links on your terminal and paste it to browser to authorize your account.

Webrat: no such file to load — action_controller/integration

paikia — Sat, 11 Feb 2012 12:49:50 +0000

When using rspec + webrat for unit testing, always pop up the error on the line: visit(edit_users_path)

Failure/Error: visit('/users/edit')
LoadError: 
 no such file to load -- action_controller/integration

If you confirmed that you have no problem with your routes.rb

The quick fix is go to spec_helper.rb

require "webrat"
require 'webrat/core/matchers'
include Webrat::Methods

Webrat.configure do |config| 
config.mode = :rack
end

and instead of :rails as default, here we use :rack

Xcode Development Pain Today

paikia — Sun, 08 Jan 2012 11:39:33 +0000

Development on Xcode sometimes can be quite painful. Because you might have problems that others never face before. Today I just fixed 2 unusual issues.

1. My app just crash when I start it. In the debug area, it just show that something like

*** Terminating app due to uncaught exception ‘NSUnknownKeyException’, reason: ‘[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key imgCover.’

After Google search and review my code looking is there any issue with imgCode in coding and xib. I find no issue at all. So in the end, I remove the link from xib, build and run it. No crash. Then added back the link, it doesn’t crash anymore also!

Surprise fixing issue eh?

2. The Code Signing Identity don’t know since when has become a text field, rather than original drop down option. Then finally I found it just by changing the Editor menu to “Show Value” then it is back again. WTF!

Fixes for invalid date format specification in gemspec

paikia — Sun, 08 Jan 2012 06:25:39 +0000

I’m getting a lot of this issue after install Heroku gem. So I found a solution for it.

The ultimate solution is this:
Search “spec” files in your Ruby directory: *C:\Ruby187\lib\ruby\gems\1.8\specifications*
If a gemspec file contains something like this: s.date = %q{2011-10-13 00:00:00.000000000Z} Then delete the 00:00:00.000000000Z part: s.date = %q{2011-10-13}
After saving those gemspec files, the problem is solved.

A faster way is

This will remove the string from the specification file: “sudo find . -type f | sudo xargs perl -pi -e ‘s/ 00:00:00\.000000000Z//’”
