OSX: install Node JS and npm in 5 mins

Prerequisites

Couple of prerequisites:

• XCode: if needed, install it through Apple Store
• Homebrew: it’s a package manager for OSX, simple and efficient.  In a terminal:
  

  ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

Install Node and npm

Once Homebrew is installed, it is very simple:

brew install node

That’s all….

If needed, to upgrade/update node

# update Homebrew
brew update
# update Node / Npm
brew upgrade node

and finally, to check current versions of Node JS/npm

node -v
npm -v

OSX : When OSX f***’ed my daily work because of systemstatsd

1st of all, a lottle bit of history: On june 2012, I bought a MacMini, then I upgraded it to 16 Gb RAM. Until couple of weeks ago, my MacMini was running quite fast for my day-to-day (development mainly) work. Then… I don’t know what happens, but suddenly, it has become slower and slower, and the HD was always on.

So, I tried couple of things : reboot, reboot and erase plist, … and so on. My HD was quite full; thus, I tried to remove a LOT of things (maily my virtual machines)

Finally, as I noticed in ‘top’ that a lot of data were constantly written, I used ‘sudo fs_usage’ and I discovered the “systemstatsd” process… This process is painful! Constantly writing, so slowing down the entire system!

I stopped it definitevely and the miracle happens ! My MacMini is back to normal ! Alleluiah!

So, couple of commands:

To STOP the systemstatsd:

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.systemstatsd.plist
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.systemstats.daily.plist
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.systemstats.analysis.plist

To START it again:

sudo launchctl load -F /System/Library/LaunchDaemons/com.apple.systemstatsd.plist
sudo launchctl load -F /System/Library/LaunchDaemons/com.apple.systemstats.daily.plist
sudo launchctl load -F /System/Library/LaunchDaemons/com.apple.systemstats.analysis.plist

And that’s it !!!

Memo : NMAP for OSX install

Everybody knows nmap, famous security tool. However, like a bucnh of tools, it is not installed by default on OSX.

Hopefully, thanks to brew (the f*** missing package manager is OSX), it is very easy to install, as usual

brew install nmap

Wait a while and it’s ready…

Setup Apache Cordova in OSX Yosemite for Android & iOS apps

To use Apache Cordova on OSX Yosemite, the prerequisites are:

• brew
• npm

I assume both are available. In this quick blog, I will assume you’d like to compile, build and emulate your app for Android and iOs. Please remember that Cordova is also available for Window Phone 8, Firefox OS, … See Apache Cordova HomePage for details.

1. Install ant using brew

   sudo brew update
   sudo brew install ant
   

2. Check ant version:

   ant -version

3. Install Cordova using npm

   sudo npm install -g cordova
   

4. if you plan to compile cordova app for android, set ANDROID_HOME to point to Android SDK

   export ANDROID_HOME=~/android/sdk/

5. If you plan to compile cordova app for iOS, install XCode from Apple Store

   https://itunes.apple.com/en/app/xcode/id497799835

   Then, you will need iOS Simulator from PhoneGap to test your app into iOS emulator:

   sudo npm install -g ios-sim
   

To make a small test project on OSX, please read Apache Cordova Starting Guide.
