Event Binding in jQuery

In jQuery, event binding can be a confusing topic at first. Especially when we attempt to do Delegated Events (or live binding , binding to elements that don't exist on the screen yet)

But first, let's clear up just a few things regarding normal event binding...

.click vs .on('click')

jQuery provides specific methods such as .click() or .mouseover() which can be used in this way

Ubuntu IP Tables (Firewall)

When setting up an Ubuntu server, you'll want to establish basic security including a firewall to only allow certain types of requests, and to allow only certain types of responses. This code will:

• Flush your current firewall
• Because it's our server and we're not hosting other people's stuff (like a shared server), we'll allow all output
• Allow input requests for SSH, Port 80 and 443 (Web and TLS (SSL))
• Log bad requests with the prefix "iptables denied:"
• Then save these rules to a file called /etc/iptables.up.rules

Get Instagram Images via JavaScript

Get API Info

You will need the user_id from the user. This is difficult to discover at Instagram but easy from this site http://jelled.com/instagram/lookup-user-id

I used http://jelled.com/instagram/access-token for the next few steps

You will also need an access token which ends up being difficult to obtain. Log into the account and go to their Developer Page.

OS X (Yosemite) Apache Environment Setup

Instructions for setting up a basic Apache environment on OS X Yosemite Only. For Mavericks, view this guide

For this guide, square brackets are used to denote places where you need to plugin your own stuff. In none of these cases are you supposed to use actual square brackets.

Note that /private/etc and /etc go to the same place on Yosemite. This is good to know for later.

If you've already configured Apache correctly and you just want to know the part about setting up a new Virtual Host, then you can skip to that section. If not, then you'll need to configure Apache.

It seems as though some people like me are experiencing a weird thing when upgrading mac these days, the RSA keys still work for connecting to things like GitHub but my keychain doesn't want to remember the password and is annoyingly asking me for it with every git push.

The solution I found that works is at http://stackoverflow.com/a/41576222

Basically, edit my ~/.ssh/config file to be:

Host *
    UseKeychain yes
