Let clean code guide you. Then let it go.

Welcome to the Galmon project! Our goals are to monitor the major Global Navigation Satellite Systems, including GPS, GLONASS, Galileo and BeiDou, but also Space Base Augmentation Systems like WAAS, EGNOS and GAGAN. Galmon is an open source & open data project with a community of over 30 station operators running more than 50 receivers. Some history of the project may be found in the second part of this blog post, and on this page on the big Galileo 2019 outage.

Last year I wrote a post listing what I had been doing in 2018, because it turned out it was a lot, so much that it was useful to summarise it somewhat. This year there is less to report, but people have wondered what I’ve been up to. And I’ve learned that if you leave room for speculation about your intentions, wrong answers tend to come up. This (professional) year for me mostly consisted of two things: DNS over HTTPS and Galileo.

A personal reflection.

Let's kick off the year with a series about Another World!

What is life? This question keeps many people awake at night and has led to rafts of definitions, some involving features (procreation, metabolism and so forth), some involving chemistry, entropy or energy flux and some are of a more philosophical bent. A BBC article noted there are over 100 definitions of life and it claims all are wrong. And indeed it does appear to be quite a challenge - every hard and fast rule is violated somewhere in biology.

Wrapping up my best reads of the year

UI Before API.

So which one should I use?

Getting a closure on JavaScript.

So it happened again, a new Redis version reached the release candidate status, and in a few months it will hit the shelves of most supermarkets. I guess this is the most “enterprise” Redis version to date, and it’s funny since I took quite some time in order to understand wh...

Note: This article covers a lot of well-trodden ground, although this post has the benefit of 1) being rather brief and 2) advancing slightly on from earlier work. Noam Chomsky wrote 39 dense pages of philosophy on this subject in “Mysteries of Nature: How Deeply Hidden”. Evolutionary’s leading light Ernst Meyr wrote a whole book called “What makes biology unique”. Finally, a lot of this thinking is also covered in the quite philosophical work “The way of the Cell” by Franklin M.

There is a playful way to study the architecture of computers of the past. Find a piece of software you know well and try to find out how it was ported to these machine you don't...

Dear anonymous internet user, dear corporate employee hiding behind a gmail.com address, dear “GitHub account with a single issue”, Thank you for your interest in my free software, my project or the documentation I wrote for you. I am happy to hear you want to ask a question, have a problem, or perhaps even inform me of a new requirement you have. But with some small exceptions (do read on), I’m afraid I will not be able to help you.

Programming, coding, and software engineering are often used interchangeably. Here is how I usually think of them. Programming Programming is solving explicit problems in a verifiable manner. It is similar to mathematical proofs. "Find an element in a sorted sequence" is a...
