Installing MongoDB with Homebrew
Installation of mysql and mongodb with brew sometimes could end with an access error, for example:
Error: Permission denied - /usr/local/var/log/mongodb
Actually, there is no proper decision yet, so the short term solution might be the following:
ls -al /usr/local/bin/brew #confirm brew ownership
sudo chown root:wheel /usr/local/bin/brew
sudo brew install mongodb
sudo chown <your user>:<your group> /usr/local/bin/brew #revert ownersh...

Getting started Spree
Full documentation can be found here:
http://railscasts.com/episodes/298-getting-started-with-spree
http://guides.spreecommerce.com/getting_started.html
https://github.com/spree/spree
This is an approximate way of spree installation.
Why 'approximate' - because docs may differ, and if installing with rails '3.2.3' causes no troubles, '3.2.6' version pulls with itself, in my case, an outdated versions of spree_core, _api and so on.
1. Create rails application
rails new app
cd app
bundle install
2. In gemfile add gem 'spree', '1.1.1'
bundle install

Dispatcher and SynchronizationContext classes in WPF
Use the Dispatcher when your code is tightly coupled to WPF.
Use the AsyncOperationManager when you need to queue something on the 'Context' thread. This works with Windows Forms, ASP .NET and WCF applications as well.
Avoid using the SynchronizationContext yourself. The AsyncOperationManager uses this mechanism internally.
Note:SynchronizationContext.Current object is of type DispatcherSynchronizationContext which is actually just a wrapper around the Dispatcher object and the Post and Send methods just delegate to Dispatcher.BeginInvoke...

Using form_tag in Ruby on Rails
In controller a "new" action creates a sample object that is just a simple object, not ActiveRecord :
def new
@item = Item.new
end
"Create" action is a post action
def create
end
And in the view the following code just displays Item object fields and posts back a hash with fields filled in on the client side:
This will create the following markup:

Updating OpenSSL on Mac OS 10.5.x
If you don't want to build OpenSSL from source and want an easy way of upgrading to the latest version of OpenSSL, I'd suggest taking the MacPorts route.
Download the correct .dmg file from http://www.macports.org/install.php.
Open it and run the installer.
In the terminal, type:
$ sudo port sync; sudo port selfupdate; sudo port install openssl
Older versions OpenSSL may require installing newer zlib, and zlib in it's turn may require installing XCode 3.1.4:
Here is the link to get XCode 3.1.4 somewhere at bottom of the page:

Rails ExecJS::RuntimeError
