How to install Oracle 11g XE in MacOS

This project enables you to install Oracle 11g XE in a virtual machine running Ubuntu 12.04, using  Vagrant  and  Puppet . Link: https://github.com/hilverd/vagrant-ubuntu-oracle-xe/tree/master Video:  https://asciinema.org/a/8438 Acknowledgements This project was created based on the information in  Installing Oracle 11g R2 Express Edition on Ubuntu 64-bit  by Manish Raj, and the GitHub repository  vagrant-oracle-xe  by Stefan Glase. The former explains how to install Oracle XE 11g on Ubuntu 12.04, without explicitly providing a Vagrant or provisioner configuration. The latter has the same purpose as this project but uses Ubuntu 11.10. Requirements You need to have  Vagrant  installed. The host machine probably needs at least 4 GB of RAM (I have only tested 8 GB of RAM). As Oracle 11g XE is only available for 64-bit machines at the moment, the host machine needs to have a 64-bit architecture. You may need to  enable vi...

Running Multiple Versions of Node.js with Node Version Manager

Image
If you work on multiple Node.js projects, you’ve probably run into this one time or another. You have the latest and greatest version of Node.js installed, and the project you’re about to work on requires an older version. In those situations, the  Node Version Manager  (nvm) has your back, allowing you to install multiple versions of Node.js and switch between them as you see fit. Getting started To get started, you will need to install the Node Version Manager, or  nvm  on your system. It is included by many package managers, or you can install it manually by running one of the following: # If you have `curl` installed: $ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash # Or if you prefer `wget`: $ wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash Copy Once installed, you will also need to add a couple of lines to your shell’s startup file ( .bashrc ,  .bash_profile ,  .zshrc , et cetera):...
