Before the ‘normal’ DevOpsDays, there was a day filled with workshops. These are the notes of the workshops that I attended.
My browser of choice has been Chromium for quite a while now. A couple of podcasts recently discussed how Chrome has become a memory hog and how Firefox has improved over the years. Time for an experiment.
This is a description of how I created a custom Vagrant box starting from a Lubuntu 14.04 desktop CD.
There are several technologies (in the Python world) to have isolated environments for projects. In this article I will describe how we use Virtualenv, Buildout and Docker for a project I’m working on at Fox-IT.
When I was experimenting with an SVG sprite to replace my current icon font, suddenly some of the icons disappeared without a clear reason. It worked fine when I accessed the demo page via the file URI scheme, but as soon as I used an HTTP server, some of them did not show up.
To introduce a coworker to our project and Django in general, I suggested that he would try PyCharm, a Python IDE. One of the (many) nice things of PyCharm is that you can easily jump to the place where something is declared—ideal for exploring a project.
The Heartbleed bug triggered a review of the configuration of my own web server. As a result I discovered that I had my Online Certificate Status Protocol (OCSP) stapling configured wrong. In this article I will briefly explain OCSP and OCSP stapling, what I had done wrong and what is a—as far as I now know—right way to implement OCSP stapling in Nginx.
Django offers useful classes to easily send email. It is also easy to add attachments to emails. I did have to puzzle a bit to get embedded images working. This article describes the way I do it now. I will first describe the most important elements and then I will show a more complete example.
When I started on a project it seemed to make sense to put a part of the project in a separate Git repository. In hindsight that wasn’t such a smart move. Here’s how I fixed it.
A site I’m working on uses
Font Awesome. Font Awesome is an iconic font
designed for use with
Twitter Bootstrap and
currently (version 4.0.0) includes 370 icons. It is an easy to use and
nice icon font. But I needed
PNG files of the icons so I could use
the same icons in a different system.
