Passwordless SSH/SFTP for dummies

To get SSH or SFTP access to a server without using a password you need to have a SSH key pair for each computer you want to be able to access the server from. In this document I’ll describe the steps you need to take to generate a key pair if you don’t have one already. If you do, you can use your public key(s) to get access to the server.

I'll also explain how to connect to your server using Cyberduck. Click here to skip to that part.

Disclaimer and stuff

This guide is written with newbies in mind, so I'm very thorough in describing the steps that you must take. This guide will not cover setting up the server side of this system. It assumes that there's a server running with SSH enabled.

Thoughts about Rails Presenters

This is a collection of links, examples and rants about Presenters/Decorators in Rails.

The "Decorator" pattern slowly started gaining popularity in Rails several years ago. It is not part of core Rails, and there's many different interpretations about how it should work in practice.

Jay Fields wrote about it in 2007 (before he switched back to Java and then Clojure): http://blog.jayfields.com/2007/03/rails-presenter-pattern.html

The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

	Instructions

	1. Add MY_url_helper.php to CI_directory/application/helpers

	2. If the CI app is already built, convert any references to site_url in your CI application (aside from the system directory) to the new namespaced function, ci_site_url.
	This step prevents Wordpress' site_url function from overwriting CIs. Because both functions are global and CI checks to make sure that site_url has not been set. Once we load the WP bootstrap file, it will have been defined, so CI's function wll never load.

	3. Add Wordpress' bootstrap file into CI_directory/index.php right above CI's bootstrap file.

	4. Update wp-includes/load.php *(this is necessary if you are using CI's sessions - Wordpress mangles CI's cookies using with magic quotes. (There may be an upgrade-proof way to do this.)
