This site has been generated using Pelican 3.3 for over two years - and I finally found some time to upgrade to the current version of Pelican, 3.6.3. This is how I did the upgrade.

I decided to be lazy and do the upgrade in-place, instead of creating a new virtualenv and copying the content & settings over. Luckily, this worked out OK, after a bit of fiddling around.

I also decided, rather cavalierly, to upgrade all the packages in the virtualenv to their latest versions while I was at it. To do this, I upgraded pip, then used pip-review. To upgrade pip & install pip-review system wide, run this on the command line:

$ sudo -H pip install --upgrade pip
$ sudo -H pip install pip-review

Then upgrade eveything in the sites virtualenv:

$ sudo apt-get install libjpeg-dev
$ workon duncanlock.net
$ pip-review …

There are quite a few changes in Pelican 3.3 - most of them minor, but a few which might mean making some changes to your site in order to upgrade. This is what I did to move my site from Pelican 3.2 to 3.3.

The change that had the biggest impact and took the most work was around image linking - caused by a combination of things. I think I was doing it wrong before and things changed in a way that meant this no longer worked. I also had to update my Better Figures & Images plugin to take this into account.

Previously, I’d been linking to my images like this, both in my theme:

/* Theme CSS Image Link */
background: #2C71B8 url(/static/images/blueprint-background.png) repeat;

{# Theme HTML/Jinja image link #}
<meta name="twitter:image" content …

reddit, the insanely popular internet community, had 71,435,935 unique visitors last month, with over 2,360,783 people logged in [1].

I say people - but it turns out that not all the denizens of reddit are human. There are also bots. Lots and lots of bots. How many? No-one really knows. [2]

This is an interesting and somewhat shadowy facet of the otherwise very public reddit community, so I thought I’d take a closer look…​

As I mentioned previously, this site was put together using Pelican - a static site generator, written in Python.

Static site generators take your content, pour it into your templates and output the result as static pre-generated HTML, CSS, JS & image files. You can then just upload the resulting folder of output to your server and you’re done. All you need on the server is a web server of some sort, like Apache or Nginx - anything really - all it’s doing is serving static pages.
