Install node.js using NVM and Homebrew on Mac OS X

Reference:http://dev.topheman.com/install-nvm-with-homebrew-to-use-multiple-versions-of-node-and-iojs-easily/
Less than a month ago, iojs was released (multiple releases followed) and 6 days ago, the v0.12.0 of node was released.
I still had the same v0.10.x (can’t remember the patch 🙂 ) of node on my computer I installed a few months ago … As a nodejs developer, I decided it was time to get rid of my old version and switch to nvm so that I could test my projects (websites and node modules) on different engines and versions – moreover not to be stuck in the case some module should only work on one or an other …
This post is more a reminder for future me when I’ll make the install again, though it could help some people.
First, you’ll need Homebrew. If you’re a MacPorts user (or a Linux user), I assume it’s nearly the same, you may even have your own way which is faster and better, no need to troll 😉 – for Windows users, you have some alternatives.
Start by :
brew update
brew install nvm
mkdir ~/.nvm
nano ~/.bash_profile
In your .bash_profile file (you may be using an other file, according to your shell), add the following :
export NVM_DIR=~/.nvm
source $(brew --prefix nvm)/nvm.sh
Back to your shell, activate nvm and check it (if you have other shells opened and you want to keep them, do the same) :
source ~/.bash_profile
echo $NVM_DIR
Now, you can install node :
nvm install 0.12
From now on, you’re using the v0.12.x of node on this shell, you can install your global dependencies such as grunt-cli (they will be tied up to this version of node).
You may want to install other versions, just do :
nvm install 0.10
nvm install iojs
...
You’ll have to npm install -g your global dependencies for each version.
Switch of node version with nvm use 0.10 (more infos here).
To have a node activated by default (not to have to nvm use on each new shell), run this (stable being the id of the version):
nvm alias default stable
Now, you can run multiple versions of node on your computer.

WPF-MVVM: RelayCommand Implementation

By
In WPF if we are implementing MVVM pattern then we need to play with Command rather than Events. You can use ICommand interface to create each command class. Implementation of ICommand in a class gives you CanExecute(), Execute() methods which take part in the action performed by Command.   Rather than making Command Class for each Command we can implement a generic Relay Command to get Command. Below is a RelayCommand class that we will implement.   ///   <summary>      ///  To register commands in MMVM pattern      ///   </summary>      class   RelayCommands  :  ICommand     {          readonly   Action < object > _execute;          readonly   Predicate < object > _canExecute;  ...
