Blogging Like a Hacker

A description of my blogging setup.

I’m Igor … wait. To learn more about me or my motivation go and read the about me page. The very first post will be meta. It describes and praise my blogging setup. It should give you a solid idea which tools I use and how to configure a similar stack. I try to list its pros and cons and share my personal opinion on the various quirks. Hope you will like it!


The keyword to my setup is Jekyll.

Jekyll is a blog aware static site generator. I use it to generate html pages from the markdown documents. It allows specifying a common layout and then focus only on the content. It takes your markdown posts, converts them to html and injects the content into the layout. It also takes care of generating a structure of folders, so your urls can be nice and blogish, e.g. /2013/03/01/my-new-framework-rocks.html.

From this point on it is straightforward - when Jekyll has done its job you’ve got a directory containing a set of html files - a full website which can be served from any static webserver like apache. I push the content to my server from where Nginx serves it.

Html generation

Jekyll is a small piece of code written in ruby. It’s straightforward to install it on ubuntu.

$ sudo apt-get install ruby1.9.1-dev  # only if you do not have ruby
$ sudo gem install jekyll

I’m not a ruby programmer, so this may be a con from my perspective. On the other hand, you do not need to dive into the code to use Jekyll.

To use Jekyll in your project you need to prepare a directory structure:

├── _includes
├── _layouts
├── _plugins
├── _posts
├── _site
├── _config.yml
└── index.html

Jekyll browsers your directories and parses any file starting with a yaml front matter, for example:

title: Lolcatz!
tagline: We teach you how make funny cat pictures
(... file content ommitted ...)

_config.yml is a configuration file for Jekyll. Your posts go to _posts directory. A base template stays in the _layouts and you can put reusable chucks of html in _includes. Jekyll’s behavior can be customized with a set of plugins. They go to the _plugins directory.

Firstly, Jekyll converts markdown/textile files into html. Htmls are considered templates and run through a liquid processor. It allows you to use constructs like loops, conditions and filters in your pages. For example, this can be used to generate a list of all posts for your archive.

{% for post in site.posts %}
  <h3>{{ post.title }}</h3>, {{ }}
  <p>{{ post.excerpt }}</p>
  <p><a href="{{ post.url }}">Read more</a></p>
{% endfor %}

Generated html is copied to _site directory. An example from my blog:

├── 2013
│   └── 03
│       └── 22
│           └── meta-blogging-jekyll-setup.html
├── about.html

    │   │   └── (...)
    │   └── js
    │       └── (...)

Markdown is a lightweight markup language. It is a plain text, easy to read and easy to write format, which can be converted to valid (X)HTML. The format is quite popular, most notably in sites like stack overflow and github. An example of its syntax:

This is a title

## And this is a header

**Strong** paragraphs are good. But you know what is better?

Lists. Lists are better:

- Because the have multiple items,
- And they are not boring.

## Another header 

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do
eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad
minim veniam, quis nostrud exercitation ullamco laboris nisi ut
aliquip ex ea commodo consequat. Duis aute irure dolor in
reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla
pariatur. Excepteur sint occaecat cupidatat non proident, sunt in
culpa qui officia deserunt mollit anim id est laborum.

With markdown you can use any text editor to create the posts. No need to run a web browser and type your thought into one of these small, ugly text areas. As matter of fact, for me any text editor is emacs.

Version control

I’m a big fan of Git. I use it wherever possible. By the way, I highly recommend to familiarize with the Vincent Driessen’s git workflow.

It seems natural to version control the blog as well. Since markdown is a plain-text format it is a perfect fit for git or any other VCS.

I turns out that a lot of blogs are stored on github. Just go there to find some inspiration or see how people use Jekyll.

Server side

Jekyll leaves you with a static web page, which is great. No need for a database or an application server. All you need is a plain old webserver like apache or nginx.

The usage of static html has many benefits:

Jekyll has its drawbacks though, most notably no dynamic server side content. You end up with a bunch of files which may or may not be what you want. You can add some spice using javascript, but having no option for dynamism means Jekyll is useful only for simple use cases. Luckily, we are building a blog. It’s simple.

Github pages

You can host your blog on github. Github pages is a free and easy to use solution to host a static content. It can be connected to your domain. It’s not as flexible as a web server, yet it is powerful enough for many scenarios.

Customizing Jekyll

Out-of-a-box Jekyll is really a plain vanilla system and you need to do some work to get the features which are usually taken for granted on modern web pages.

Please note there are projects like Octopres which aim to deliver a preconfigured and themed Jekyll - so you can start right away. Even if you don’t want to use their solution it’s worth to go through its source code for idea to organize and customize your setup.


To publish an rss feed means essentially to prepare a template (we can call it rss.xml) which will take your latest posts and generate a file compliant with the RSS specification.

I started from this rss.xml file and ended up with something like that:

layout: nil
<?xml version="1.0"?>
<rss version="2.0" xmlns:atom="">
    <title>Geek Igor</title>
    <link>{{ site.url }}</link>
    <atom:link href="{{ site.url }}/rss.xml" rel="self"
	       type="application/rss+xml" />
    <description>A blog on software development by Igor Kupczyński</description>
    <pubDate>{{ site.time | date: "%a, %d %b %Y %H:%M:%S %z" }}</pubDate>
    <lastBuildDate>{{ site.time | date: "%a, %d %b %Y %H:%M:%S %z" }}

    {% for post in site.posts limit:5 %}
      <title>{{ post.title }}</title>
      <link>{{ site.url }}{{ post.url }}</link>
      <pubDate>{{ | date: "%a, %d %b %Y %H:%M:%S %z" }}</pubDate>
      <author>{{ }} {{ }} </author>
      <guid>{{ site.url }}{{ }}</guid>
	  &lt;p&gt;Tags: {{ post.tags | join ', ' }}&lt;/p&gt;
	  {{ post.excerpt | xml_escape }}
	  &lt;/p&gt;| &lt;a href=&quot;{{ site.url }}{{ post.url }}&quot;&gt;
	  Read more&lt;/a&gt;&lt;/p&gt;
    {% endfor %}


It generates a header for the feed, then iterates through the latest five posts and puts them in the feed.

You should also attach the feed address to head section of your pages. Just like this.

<link rel="alternate" type="application/rss+xml" title="Latest posts"

It will result in an icon which indicates that a feed is available.


Jekyll uses a plugin mechanism to let the world extend its behavior. To install a plugin just drop a ruby file into the _plugins directory.

Since I do not do ruby I need to use plugins released by the community. A following scenario may be a good example of how plugins are useful.

You need to be able to extract a lead of an article. Be it the first paragraph that you want to include on your homepage and in your rss feed. Nobody will click on a title alone, so we need to let our visitors peek into an article - to catch their interest.

Such a future is not available in a latest version of Jekyll in ubuntu repository (Jekyll 0.12.1). Hence we need to find a plugin. I use this one: excerpt.rb. It simply exposes excerpt as an attribute of a post.

{% for post in site.posts %}
	<p>{{ post.excerpt }}</p>
{% endfor %}


A lot of blogs on Jekyll does not use pagination at all! People tend to have a flat list of their articles, containing only titles. This approach for sure lets you compress a lot of posts on your homepage, but it just does not feel right for me. I wanted to have more blogish approach. Namely, a few posts with their excerpts on the home page and a pagination to access older posts.

Luckily there is a built-in solution. It’s described on the Jekyll wiki. You need to set up how many posts per page should be present. This is done in your _config.yml file.

paginate: 5

And then you add some liquid syntax on the home page. Here’s an example from this blog:

<div class="pagination pagination-large pagination-centered">
    {% if paginator.previous_page %}
            {% if paginator.previous_page == 1 %}
                <a href="/">&laquo;</a>
            {% else %}
                <a href="/page{{paginator.previous_page}}">&laquo;</a>
            {% endif %}
    {% else %}
        <li class="disabled"><a>&laquo;</a></li>
    {% endif %}
        {% if == 1 %}
        {% else %}
		    <a href="/">1</a>
        {% endif %}
    {% for count in (2..paginator.total_pages) %}
            {% if count == %}
            {% else %}
                <a href="/page{{count}}">{{count}}</a>
            {% endif %}
    {% endfor %}
    {% if paginator.next_page %}
        <li><a href="/page{{paginator.next_page}}">&raquo;</a></li>
    {% else %}
        <li class="disabled"><a>&raquo;</a></li>
    {% endif %}

I’ve put it in the _include directory as pagination.html and set it up on home page like this.

{% include pagination.html %}


That’s the hard part. At least it used to be. A clean, browser compatible and good looking design is hard to achieve. Especially that, nowadays, you’re expected to cover mobile devices as well- your design needs to be responsive.

Luckily, there is a hope for us. It’s called [Bootstrap][bootstrap], it’s from twitter and it’s hot. Believe it or not, but hundreds of pages nowadays base their layout on bootstrap.

Bootstrap calls itself a front-end framework. It provides a layout, i.e., a responsive grid, a lot of components, and a ready-made design in a form of cascade style stylesheets. If you don’t like its default look, or just want to stand out from the crowd, there are good-quality themes, both free and paid, available at bootswatch. Bootstrap csses are very clean and therefore it is easy to customize it if you so wish.

It is worth noting that there are some alternatives, like zurb foundation or yaml4. I’m not a css geek so I decided to use Bootstrap as other cool kids do.


In a truly agile sprint I decided to prioritize my features and deliver a working software with only a subset of them. As a part of the first iteration of course.

Couple of items are missing and I hope to add them in near future. On my short list are currently:

Figure tag

Markdown is great, but inserting images with it may be tedious. It’s better to use a liquid tag, like this or this. I want it also to support new html5 figure syntax.

Another open question is how to handle images. I keep the source code for this blog in a repository, but I do not want to bloat it with images accompanying posts. There are some options here to evaluate.

Asset pipeline and build process

The csses attached to this page are not optimized or mimified in any way. It seems a waste not to optimize them. I do not want to do it manually, therefore I need an automated process to do it for me. This process will be also useful for building and pushing the blog content to my remote server. Automation is very high on my priority list.

Random pages

My current version of “About Me” sucks. I need to work on that. Also, there is a lot of nice examples of 404 pages out there. Need one for this weblog.

Social items

I have a vague plan to attract a lot of traffic to this weblog using my twitter account.

Apart from that, I plan to include comments on the site.

Sounds nice, but it means simply to have a page archiving all posts under a given tag and to link to similar posts in an automated manner.

Org mode

Emacs rocks. Period. And it’s great for markdown.

However I heavily rely on org-mode as a note-taking tool. Org-mode has a great html exporter. There should be a way to combine it with Jekyll and write my posts with the org syntax.

Org mode FTW
Org mode is for keeping notes, maintaining TODO lists, planning projects, and authoring content.

What’s next

Time to do some real work. I hope more posts will follow, and moreover, I hope they will be useful.
