A Guide for WireGuard VPN Setup with Pi-Hole Adblock and Unbound DNS
I’ve used Mullvad as my VPN provider for a few years. Their service is good, they provide keys for 5 devices, rely on the Wireguard protocol, and offer alternative configurations as well. Despite that, my needs have changed and I wanted to be able to have granular control over DNS queries and the ability to connect my…

Reverse Engineering a Docker Image
This started with a consulting snafu: Government organisation A got government organisation B to develop a web application. Government organisation B subcontracted part of the work to somebody. Hosting and maintenance of the project was later contracted out to a private-sector company C. Company C discovered that the…

Why is there only one Snap Store?
Snap and Flatpak are the basis of two universal app stores for Linux: the Snap Store and Flathub. Interestingly, Flatpak has multiple repositories: Flathub is the main one but both Fedora and Elementary OS also host their own store. In contrast; there is only one Snap store. Why is that?

Serving 200M requests per day with a CGI-bin
In the early 2000s, we used to write a lot of CGI programs. This was the primary way to make websites dynamic at the time. These CGI programs were usually written in Perl, but sometimes in C to increase performance. The CGI mechanism is conceptually simple but powerful. When the web server receives an incoming request…

Why I dislike systemd
As a Linux sysadmin in the 2010s, it's hard not to have an opinion on systemd. But what I find baffling about it is how divisive it is; nearly everyone (or at least the most vocal crowd) seems to either love it or hate it. When I tell people that systemd was the catalyst for my defection to OpenBSD last year, their…

I don't want to host services but I do

A Cold Take on IBM, Red Hat and Their Hybrid Cloud
I start more blog posts than I finish, due to no shortage of other distractions and at times a near-crippling inability to blog short. When IBM announced they were acquiring Red Hat in October 2018…

Celery – Best Practices
If you’ve worked with Django at some point you probably had the need for some background processing of long running tasks. Chances are you’ve used some sort of task queue, and Celery is currently the most popular project for this sort of thing in the Python (and Django) world (but there are others).

Why we’re really happy with AppEngine (and not going anywhere else)
There’s been a handful of articles critical of Google’s AppEngine that have bubbled up to the top of Hacker News lately. I’d like to throw our story into the ring as well, but as a story of a happy customer rather than a switcher.

Passive Solar Water Desalination
I know we are supposed to be worried about the world supply of fresh water. I have been hearing that at least for the last 40 years, and the statistics are alarming. According to the Global Commission on the Economics of Water: "We are seeing the consequences not of freak events, nor of population growth

I push, therefore I am: two days at Etsy (2013)
Netflix and Etsy ran a brief "developer exchange program" in 2013. Etsy sent one of their best to hang out at Netflix for 2 days. And a few months later, Netflix sent... me. This was a writeup of the experience that I shared with my team at Netflix and the people I interacted with at Etsy. It was fun to write, I…

Working on Multiple Web Projects with Docker Compose and Traefik
Docker Compose is a brilliant tool for bringing up local development environments for web projects. But working with multiple projects can be a pain due to clashes. For example, all projects want to listen to port 80 (or perhaps one of the super common higher ones like 8000 etc.). This forces developers to only bring…
