On Staticness

For almost 7 years, now I’ve had a desktop at home, running, serving (among many things) my personal blog. Doing so is how I learned much of what I now know about programming and system administration. It gave me a reason to learn HTML, then PHP, then finally Haskell. It taught me Postgres, Apache, then lighttpd, then nginx. Without maintaining this site myself, on my own desktop, I doubt I would’ve been sucked into these things and I may not have ended up where I am today.

However, I’m now a happily employed Developer and I do these things all day on other people’s machines and sites. Don’t get me wrong, I enjoy it all very much, but the educational value of maintaining my personal blog as a locally-hosted web-app is just not there any more. With that value gone, things like power outages, harddrive failures, Comcast, etc which bring my site down become unacceptable. It’s too easy to have something which requires almost no maintenance while still giving me the control and work-flow I want.

I realize I could’ve moved my site as-is to a VPS and no longer been at the whim of Comcast and NSTAR, but that wouldn’t decrease the maintenance burden enough. Contrast pretty much any typical web-app ecosystem with…

The services now required to host my blog:

nginx

The configuration required to host my blog:

$ wc -l < /etc/nginx/nginx.conf
19

Adding a new post:

$ cat > posts/2013-09-21-awesome_post.md <<EOF
---
title: Awesome Post
tags: some, tags
---

Pretty *awesome*.

EOF

Deployment:

$ jekyll build && rsync -a -e ssh _site/ pbrisbin.com:/srv/http/site/

Backups:

$ tar czf ~/site.backup _site

Comments

Unfortunately, Comments aren’t easy to do with a static site (at least not without something like Disqus, but meh). To all those that have commented on this site in the past, I apologize. That feature is just not worth maintaining a dynamic blog-as-web-app.

When considering this choice, I discovered that the comments on this site fell into one of three categories:

  1. Hey, nice post!
  2. Hey, here’s a correction
  3. Hey, here’s something additional about this topic

These are all useful things, but there’s never any real discussion going on between commenters; it’s all just notes to me. So I’ve decided to let these come in as emails. My hope is that folks who might’ve commented are OK sending it in an email. The address is in the footer pretty much where you’d expected a Comments section to be. I’ll make sure that any corrections or additional info sent via email will make it back into the main content of the post.

Pandoc

At some point during this process, I realized that I simply can’t convert my post markdown to html without pandoc. Every single markdown implementation I’ve found gets the following wrong:

<div class="something">
I want this content to **also** be parsed as markdown.
</div>

Pandoc does it right. Everything else puts the literal text inside the div. This breaks all my posts horribly because I’ll frequently do something like:

This is in a div with class="well", and the content inside is still markdown.

I had assumed that to get pandoc support I’d have to use Hakyll, but (at least from the docs) it seemed to be missing tags and next/previous link support. It appears extensible enough that I might code that in custom, but again, I’m trying to decrease overall effort here. Jekyll, on the other hand, had those features already and let me use pandoc easily by dropping a small ruby file in _plugins.

Update: I did eventually move this blog to Hakyll.

I figure if I want to be a Haskell evangelist, I really shouldn’t be using a Ruby site generator when such a good Haskell option exists. Also, tags are now supported and adding next/previous links myself wasn’t very difficult.

With the conversion complete, I was able to shut down a bunch of services on my desktop and even cancel a dynamic DNS account. At $5/month, the Digital Ocean VPS is a steal. The site’s faster, more reliable, easier to deploy, and even got a small facelift.

Hopefully the loss of Comments doesn’t upset any readers. I love email, so please send those comments to me at pbrisbin dot com.
