Steps to install nodejs on Raspberry Pi B+ (armv6)

Steps to install nodejs v6.2 on Raspberry Pi B+ (armv6)

cd ~
wget http://nodejs.org/dist/v6.2.1/node-v6.2.1-linux-armv6l.tar.gz
tar -xzf node-v6.2.1-linux-armv6l.tar.gz
node-v6.2.1-linux-armv6l/bin/node -v

The last command should print v6.2.1.

Now you can copy it to /usr/local

Steps to configure my raspberry pi with Rapsbian Jessie using silentinstall (headless installation)

Install Raspbian Jessie on Raspberry Pi using silentinstall (headless installation), ready for SSH access

This http://raspberrypi.stackexchange.com/a/19928 is an amazing guide but it is not up to date. So I modified it here to document the steps I followed to install Raspbian Jessie on my Raspberry Pi. You can refer to that guide for more details.

Using only the laptop's screen and keyboard (both before and after installation), install and configuration for headless operation using SSH is possible using NOOBS (they call it "silent install"). It does not require a separate screen or keyboard/mouse. It does require an SD card reader on the laptop (built in or external USB), though.

The only thing required on the Raspberry Pi side is an Ethernet connection (to SSH into it from a host system). Alternatively, using special hardware (USB-to-serial adapter), it possible to use some GPIO pins on the Raspberry Pi.

Workaround to install Vagrant 1.7.4 on Mac OS X El Capitan

After using the installer vagrant_1.7.4.dmg I got this error when trying to use vagrant from the console on Mac OS X El Capitan:

-bash: vagrant: command not found

So, after reading this bug report hashicorp/vagrant#6034 I created a new bin/ folder in this way:

cd /usr/local

Below are the summarized steps based on that documentation.
