Meet Doctor Jekyll

My wordpress blog has lasted longer than any site I’ve used before, but I finally got sick of it and switched. So now I’m on Jekyll.

Wordpress is an incredible blogging-platform-turned-CMS that provides many things I wouldn’t want to do myself. It’s been an incredible SEO asset and worked beautifully on shared hosting. I would still recommend it to anyone who wants to write a blog and doesn’t want to spend much time customizing or setting things up. There are plenty of nice looking pre-made themes and plugins to do pretty much anything you want.

Wordpress to Jekyll - Why I switched

Jekyll is “a blog-aware static site generator in Ruby”. Basically what this means is that all the pages you see on this blog are generated once - not generated on demand every time they’re requested. There’s no DB backend, no scripting language running on the server side. These are just plain HTML pages.

I started off with a template I got off here: github.com/krisb/jekyll-template. But if you’re planning on starting a blog similar to mine, don’t start from scratch like I did - go check out Octopress. It provides a lot of niceties for blogging hackers that Jekyll doesn’t out of the box.

So why did I switch?


While Wordpress is completely skinnable - it’s a pain in the ass. I really just wanted to start from scratch and only build the things I absolutely needed. There is one unifying layout and only 2 types of page on this site: the posts list and posts. It means I can set my own structure for everything and keep it much, much simpler than it would have been on Wordpress.


I love vim. I feel like I’m dragging a huge weight when I need to edit text - especially code - without vim. Since Jekyll just generates my site from code, it means I can edit everything including this post in vim. All I do is spawn up a local Jekyll server (WEBrick) and there’s my preview. Once I’m done, all I have to do is commit the changes to git, and then I pull down the changes on my server - which is now hosted on EC2, with help from Andrew Tinits.


I’ll be honest here - I feel cooler running Jekyll than Wordpress. And having the source for my blog on github just feels right. Seriously: github.com/jlfwong/blog.

Plus there’s nothing better to motivate you to write a blog post than redoing your entire blog. I promise I won’t be another person who just writes a blog so they can write about how they set up their blog and then never write again (you know who you are.)

The Tech

Here’s the part where I justify you spending the time reading this post by rambling about technology you might be interested in.


Markdown is a content writing language for the web which compiles (primarily) down to HTML. The idea is that it enables you to write documents that are still readable in plaintext, but compile to useful HTML. This means having a nice syntax for headers, emphasis, links, images, lists and a couple of other things. It’s definitely much nicer than raw HTML for writing up blog posts.

As a quick example, it takes this:

### Markdown

Markdown was written by John Gruber of [Daring Fireball][].

As a quick example, it takes this:

    Hello World

    I am pretty awesome

and produces this:

    <h2>Hello World</h2>

    <p>I am pretty awesome</p>

[Daring Fireball]: http://daringfireball.net/

and produces this:


<p>Markdown was written by John Gruber of <a href="http://daringfireball.net/">Daring Fireball</a>.</p>

<p>As a quick example, it takes this:</p>

<pre><code>Hello World

I am pretty awesome

<p>and produces this:</p>

<pre><code>&lt;h2&gt;Hello World&lt;/h2&gt;

&lt;p&gt;I am pretty awesome&lt;/p&gt;


Sass is awesome syntactic sugar for CSS. It deals with a bunch of things that are simply a giant pain in vanilla CSS. One of my favorite things it does is deal with nesting for you.

    font-size: 20px
    font-size: 18px

      text-decoration: underline

Turns into:

.container h1 {
  font-size: 20px; }
.container h2 {
  font-size: 18px; }
  .container h2:hover {
    text-decoration: underline; }

Since it runs through a compiler before producing CSS, it lets you do some very useful things before producing the raw CSS. One of the most valuable things for me while working on this site was variables. It means you can do things like this:

$base-color: #281e17
$content-width: 500px
$sidebar-width: 150px

  background-color: lighten($base-color, 50%)
  $padding: 20px
  padding: $padding
  width: $content-width + $sidebar-width - 2 * $padding

    width: $sidebar-width
    background-color: lighten($base-color, 25%)

    width: $content-width
    color: $base-color

And get back this:

.container {
  background-color: #b99a85;
  padding: 20px;
  width: 610px; }
  .container .sidebar {
    width: 150px;
    background-color: #795b46; }
  .container .content {
    width: 500px;
    color: #281e17; }

The really cool thing about the color functions is that you can base your entire website off only a few colours, then make everything relative to those. This site (at time of writing) actually only has two colours specifically defined - the content font color and the body background. Everything else is relative to those.


Compass is a collection of mixins and utilities for sass. It’s especially useful for CSS3 related tasks, since it does all the proprietary browser prefixes (-O-, -moz-, -webkit-) for you when you do things like +box-radius.

It also comes with Blueprint, which gives you a great starting point to have all the default styles for things (margins, typography, resets) look nice out of the box.


Pygments is a syntax highlighter which produces HTML output which can then be styled with CSS. Github uses a wrapper around it called Albino to do all the syntax highlighting you see on the site, and it’s what I’m using to make pygments work in Jekyll.

I’m actually using a custom Jekyll plugin to deal with all of this because I didn’t want to have to stick liquid tags in my posts. In retrospect, this was probably really unnecessary, but it’s done now.

You can see the plugin here: markdown.rb

Google Web Fonts

Google Web Fonts let you use a number of beautiful fonts that may not be available on your visitor’s machine on your websites. I’m currently using it for my logo, sidebar and headers.

Using it is beautifully simple. All you have to do is drop a link tag in the head like the one I’m using:

<link href='http://fonts.googleapis.com/css?family=Questrial|Sansita+One' rel='stylesheet' type='text/css'>

And then use it like normal in a CSS rule, like so:

font-family: Questrial, "Helvetica Neue", Arial, Helvetica, sans-serif


Since I had to set up my own web server to run this, I decided I’d try messing around with nginx since it looks much nicer to configure than apache. For the longest time, I thought it was pronounced “en-jinx”. The actual pronounciation, “engine-ex” made a lot more sense once I heard it.

Setting up this server was extremely simple. Since I’m only serving static files, all I really needed was the following:

# Redirect any subdomain to the main domain
server {
  server_name *.jamie-wong.com;
  rewrite ^ http://jamie-wong.com$request_uri? permanent;

server {
  listen 80 default;
  server_name jamie-wong.com;
  server_name_in_redirect off;

  access_log /var/log/nginx/jamie-wong.com.log;

  index index.html index.php;

  try_files $uri $uri/ /404/ =404;

  # If it's in any of these folders I migrated from
  # my shared hosting on dreamhost, load it directly
  location ~ ^/(experiments|asciiconvert|life|Jobmine-Improved|V10|1yr)/ {
    root /var/www/jamie-wong.com/;

  # Otherwise, it's probably a blog page, so load it
  # from Jekyll's generated _site directory
  location ~ / {
    root /var/www/jamie-wong.com/blog/_site/;

  error_page  404  /404/;

This got a lot longer than I expected it to. Time for sleep - will proofread tomorrow.
