New blog backend

Recently I changed the way this website is hosted, served and deployed. I’ll describe what I changed and why I did so.

Open tabs

Currently I have about 30 tabs open in the browser on my phone. Quite a bunch of them I have open because I want to read the article in the future, already have read the article and want to reread or act on it, or a combination of the above. In this article I list the open tabs (and some notes) so I can close them on my phone, but still have a reference to them.

How to create a Debian VirtualBox machine with Packer with an additional host-only adapter

For a project I am working on, there is this virtual machine we can use to do our development work in. This machine has grown organically and I want to replace it with something I can reproduce.

OCSP Stapling in Nginx

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 know now—right way to implement OCSP stapling in Nginx.

Last year I participated in a deployment knowledge sharing session and I started implementing changes at my company pretty soon after. The result is that we are using Puppet for some parts of our server configuration. We also added Munin to our monitoring toolset (and I used Puppet to deploy Munin and manage its configuration). But an important piece that was still missing in our setup was an overview of which packages we use in the buildouts of our clients and more specifically which version each client uses.

Google’s Webmaster Tools provide the modern webmaster/developer with some nice tools to improve a website and the way the site is indexed. In this article I’ll focus on the crawler related tools. Specifically, how they helped me when I migrated from Plone to Django.
