Ten Bitcomb Ravenstine

I had a case where I wanted components to know if the current route has changed so behavior within their scope could be triggered. This was very hard to do, but this is what I came up with and it seems to work pretty well:

  didInsertElement() {
    Ember.run.scheduleOnce('afterRender', this, function() {
      let router = this.container.lookup('router:main');
      router.addObserver('currentPath', function(){
        // ... do something here
      });
 });

Ravenstine's Bullshit Google Results Blocklist

This is my list of domains that I block from Google search results using the Personal Blocklist plugin for Google Chrome.

Criteria

Here is the list of reasons why I block these domains:

Spreads misinformation or misleads the reader
Has a social, religious, or political bias
Uses clickbait headlines

Ruby Snippets

Sometimes, you don't need a gem for it.

This is a list of useful "snippets" for Ruby that are small but provide a lot of power. Copy them, modify them, and make them your own!

Host to Host a Rails App on a Home Server

Hosting services like Heroku and Amazon EC2 are nice. That is, until they cost money. Some things are worth running on your own hardware, especially when the cost and Terms of Service requirements outweigh the expense of rolling your own hosting.

I am writing this because I recently had to figure all this out in order to host a personal blog off a Raspberry Pi, and I thought I'd share what I learned. This guide assumes that you already know how to install Ruby and you know how to use Rails. If you don't, look those up first before coming back to this guide.
