Google Analytics goals in Ruby On Rails

I had a task to track GA goals. A problem was some action has redirection to third-party resource OAuth.

I decided to use RoR's flash. Category and action information is stored in 'ga_action' key in flash.

The GA's default embed code was modified a little bit.

iOS development

I released two applications for local-country use so far:
Currency rates of our national bank and news application.

Programing iOS devices is very funny.
I had very little experience of C programing and knew how memory, cpu, compilers work from university and this knowledge helped a lot.
There is a long way before I can say that I'm experienced in this field but I released more or less stable product and I'm very glad of it.

Now I'm reading Kochan's "Programing Objective-C" book. Strong familiarity with ObjC will help me improve a level of my apps.

Weird "C compiler cannot create executables" error

After upgrading to Mac OS X Lion 10.7.3 I wanted to install pdnsd from homebrew.
When I run "brew install pdnsd" (or any homebrew formula), I got "checking for C compiler default output file name... configure: error: C compiler cannot create executables".

To solve this problem you need to:

  1. Install XCode from app store.
  2. Install Command Line Tools in XCode Prefenences -> Downloads.

CruiseControl.rb and Rails 3 with RVM

Hello. There is no article how to configure CruiseControl.rb(ccrb) for Rails 3 with RVM on internet so far. That's pity. Let's fix it.

First, install ccrb (just download and unzip from
Create new ccrb project named 'your_project'.

Then let's open ~/.cruise/projects/your_project/cruise_config.rb with your favorite editor.
Uncomment next line:
project.build_command = './'
Add to your rails application so full path should be ~/.cruise/projects/your/project/work/ 
This file should contain next lines:
# Load RVM into a shell session *as a function*
if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then
# First try to load from a user install
source "$HOME/.rvm/scripts/rvm"
elif [[ -s "/usr/local/rvm/scripts/rvm" ]] ; then
# Then try to load from a root install
source "/usr/local/rvm/scripts/rvm"
printf "ERROR: An RVM installation was not found.\n"


bundle install
bundle exec cucumber

Start ccrb and build.

rvm's zlib issue

I had problem with rubygem in rvm's ruby because ruby wasn't compiled with zlib support. You can avoid this issue if you'll install this packages:
sudo apt-get install zlib1g-dev libssl-dev libreadline5-dev libxml2-dev libsqlite3-dev

In memory sqlite database for testing Rails 3 app with Cucumber and RSpec

Let me introduce you my way of using in memory database inspite of existence of plenty articles regarding this on internets.

test: &test
adapter: sqlite3
encoding: utf8
database: ":memory:"

In cucumber's features/support/env.rb in Before paste this:
load_schema = lambda {
# use db agnostic schema by default
load "#{Rails.root.to_s}/db/schema.rb"

# if you use seeds uncomment next line
# load "#{Rails.root.to_s}/db/seeds.rb"
# ActiveRecord::Migrator.up('db/migrate') # use migrations
silence_stream(STDOUT, &load_schema)

Add lines below to spec/spec_helper.rb:
load_schema = lambda {
load "#{Rails.root.to_s}/db/schema.rb" # use db agnostic schema by default
# ActiveRecord::Migrator.up('db/migrate') # use migrations
silence_stream(STDOUT, &load_schema)

XAMPP 403 Access Forbidden Problem

It's the second time when I got "403 Access Forbidden" in XAMPP under Mac OS X. First time I solved somehow.
Today I found what the problem is. I just set my User and Group parameters in /Applications/XAMPP/etc/httpd.conf.

You may think it's obvious but I've never set this things on Linux.
