Creating my website with Hugo


For some time I’ve had a strange need for a personal website, though I didn’t even know what content to share. The idea of having a blog felt a bit weird to me, as I was wondering for whom this might be meaningful. It took me a while, but meanwhile I think completely differently about this.

  1. You do not have to write long papers that meet academic requirements. Small things can matter, and also imperfect ones. Admittedly far from being imperfect, Adam Bien’s Blog posts are always succinct and usually provide elegant and low complexity solutions to very concrete problems. It’s especially because of this brevity that they are easily consumable and very worth reading. Having the infrastructure already set up lowers the hurdles to publish even small content.

  2. Other people and companies can gain insight into your interests and current projects. This can also be helpful to get in touch.

  3. You do not know if you have fully understood a certain topic until you have explained it to someone or have written it down. In turn when blogging you ensure a proper understanding.

And at least with every blog post I will get some more practice with my English skills. πŸ‡ΊπŸ‡Έ


While doing a first bit of web research for appropriate technologies it seemed that WordPress is the most popular system for websites with blogs. However, I couldn’t bring myself to accept the downsides. Under no circumstances I wanted to host the system myself. Even though there are countless WordPress hosting providers you either have annoying limitations like ads on your site or a regular downtime. Or you have to pay for the service. Besides that WordPress felt like a complex and feature-blown system that is hard to tame, especially if you are relying on the installation of your hosting provider and cannot just apply a change. Migrating WordPress sites from one provider to another seems to be easily manageable by export/import functionality. Nevertheless, you still have some kind of vendor lock-in for your precious content.

Inspired by Trisha Gee’s blog post Converting Blogger to Markdown I came across text file based generators for static websites with basic Content Management Features. It’s the perfect fit! I can write the content in simple text files, e.g. in Markdown syntax. Definitely no vendor lock-in! And I can easily put them into a version control system. I use a GitHub repository for this. As I also have the local copy of the repository on my machine I feel sufficiently safe and even resign an additional backup. It takes a mere run of the generator to get the readily deployable website in the output directory. Upload this directory to the web hosting provider of your choice and you’re done. I chose GitHub Pages, simply because it’s free, I already have a GitHub account, and I like the deployment process of just doing a git commit/push to my repository.

Jekyll or Hugo?

The two currently most popular static site generators are Jekyll and Hugo, at which I had a closer look. I took the following factors into account:

  • Still being actively developed and maintained?
  • Documentation
  • Programming language, installation, and dependencies
  • Performance
  • Writing/development workflow
  • Built-in features
  • Extensibility and flexibility
  • Theme support
  • Syntax highlighting for code samples
  • Support for mathematical notation in content

There is a recently published and very nice comparison by Chris Macrae, which I used as a starting point: Hugo or Jekyll? 6 Factors You Should Know. As my requirements are fairly low and both options are battle-tried mature tools, it is clear that either of them would definitely meet my requirements. Nevertheless, I did a comparison.

Soon a tendency towards Hugo became apparent. Although my site is just a tiny one I cannot make a secret of the fact, that performance was one reason. And this is where Hugo beats the pants off Jekyll. I also liked the ease of installation, as Hugo is written in Go and comes as a self-contained binary. This seemed easier than fiddling around with the Ruby Gems of Jekyll. I have not been intimidated by the reputed steeper learning curve of Hugo’s template syntax but rather appreciated the rich feature set. This is purely subjective of course.


So I gave Hugo a try. First I had to decide if I wanted to write all layout templates from scratch or pick one of the numerous available themes. As I want to concentrate on the content and do not like to re-invent the wheel, I decided to use a theme as a basis. Besides that I am no UI/UX expert and it probably would take me a lot of time to come up with an appealing result. I did not agonize about this decision for a long time: If I do not like my current theme anymore, switching themes should be a piece of cake.

As a theme I chose Academic, mainly because of its clean design and as it is still being actively maintained. As a plus it ships with a couple of nice widgets that you can integrate into your site.

Using a theme is done by copying it to the themes/ directory and enabling it in the site config file. I did not just copy the theme, but added a fork of the theme repository as a Git submodule. This has basically two advantages. I can easily benefit from new releases simply by synchronizing my fork and updating the module. Furthermore, if I add features or bug fixes to the theme that also others might find useful, I can easily create a pull request.

Experience so far

So what is my impression after toying with Hugo for a couple of hours and writing my first blog post?

The installation is super easy and you quickly get to the point where you have set up a basic site that can be taken as a starting point for further improvements. From the decision to try out Hugo to an already nice looking example site it took me around 1 hour.

The workflow is really awesome. Running hugo server generates the site to a directory and starts a web server to serve it. A watch dog recognizes any changes to input files and triggers a re-build. In combination with the live-reload feature and a browser window on the second screen or split screen, you can thereby get a WYSIWYG-like experience during writing.

Here Hugo’s performance really excels. I do not care if the final build of my small site takes a second or a minute. But during writing I like to have a regular look at the rendered result. And then even seemingly small generation times could easily get annoying. When saving changes to the file of this (nearly ready) blog post the changes become almost immediately visible in my browser window. Hugo states total times of something between 7 and 20 ms. But I also observed some hiccups. Now and then the watch dog fails to detect my changes. But this is no big deal — I simply save again or restart the server.

The documentation makes an excellent impression. It is very detailed and I found answers to all my questions so far. To me it is great fun to explore all the possibilities of Hugo and apply changes to the site layout. If you do not want to provide these changes as a pull request to the theme repository, Hugo greatly supports this. Besides the theme directory there is an identically structured global site directory which takes precedence over the theme files. E.g. if you wanted to add a keywords meta tag to the page header (which you do not want anymore) you would simply copy themes/academic/layouts/partials/header.html to layouts/partials/header.html and add the following line

<meta name="keywords" content="{{ delimit .Keywords ", " }}">

As your changes reside in a dedicated directory it is always immediately clear in what aspects your site layout deviates from the theme.

And what about syntax highlighting? A first try using standard Markdown syntax looks quite appealing:

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello world!");

In one of the next blog posts I will explore further capabilities like adding line numbers, folding etc.

For writing mathematical stuff you have basically all the math notation capabilities of $\LaTeX$ available. First experiments work exactly as expected: $$ x_{1,2} = -\frac{p}{2} \pm \sqrt{\frac{p^2}{4} - q} $$

Overall I can state that I am super happy with the decision so far! Let’s see how this evolves when I get to know Hugo a bit better. πŸ˜‰

Hello World!

The bare site went online on May 11, 2018. This is my first blog post. Feels great to be prepared for easily providing more content! πŸš€
