I den här artikeln kommer vi att gå igenom hur man sätter upp en minimal installation av en Matrix homeserver med Synapse-implementationen. Denna server kommer att kunna federera med andra servrar, för att fullt ut delta i det offentliga Matrix-nätverket.
TLDR: Ifall du vill köra på snabbspåret, kika längst ner i artikeln, där finns det en sammanfattning som endast innehåller konfigurationsfilerna.
All mjukvara i denna ... [continue reading]
In this article we will cover how to setup a minimal installation of a Matrix homeserver using the Synapse implementation. This homeserver will be able to federate to other homeserver to completely participate in the public Matrix network.
TLDR: Look at the bottom of this article, there is a summary if you just want the configuration files.

Open source i offentlig sektor - utmaningar, möjligheter och vägen framåt.
Denna artikel beskriver processen och lärdomarna från att släppa ett API som öppen källkod inom offentlig sektor. Projektet, som utvecklades för digitala nationella prov (“DNP”), visar hur öppen källkod kan stärka samarbete, transparens och innovation. Artikeln lyfter fram både möjligheter och utmaningar – från säkerhet och juridiska aspekter till kulturellt motstånd – och ger insikter för andra myndigheter som överväger liknande initiativ.
Slutsatsen är att öppen källkod ... [continue reading]
Ansible can be used for many things. There are only a few things I have on my bucket list of things I would like to do, where Ansible cannot help me.
One of my most urgent things to handle was the increasing complexity of Ansible, its configuration and in particular the role development. As I got deeper into Ansible, more and more factors needed to be taken into consideration when setting up a role: the role structure, linting issues, molecule ... [continue reading]
Working with various compressed files on a daily basis, I found I didn’t actually know how the different tools performed compared to each other. I know different compression will best fit different types of data, but I wanted to compare using a large generic file.
The file I chose was a 4194304000 byte (4.0 GB) Ubuntu installation disk image.
The machine tasked with doing of the bit-mashing was an Ubuntu with a AMD Ryzen 9 5900X 12-Core ... [continue reading]
It can probably be understood from my previous blog post that if it was up to me, I’d avoid products like CrowdStrike - but every now and then I still have to install something like that. It’s not the idea of “security software” per se that I’m against, it’s the actual implementation of many of those products. This post lists up some properties that should be fulfilled for me to happy to install such a product.
Unless you’ve been living under a rock, you probably know that last Friday a global crash of computer systems caused by ‘CrowdStrike’ led to widespread chaos and mayhem: flights were cancelled, shops closed their doors, even some hospitals and pharmacies were affected. When things like this happen, I first have a smug feeling “this would never happen at our place”, then I start thinking. Could it?
Our department do take responsibility for keeping quite a lot ... [continue reading]
At my work, we’re very much dependent on alarms. The systems need to be operational 24/7. When unexpected issues arise, timely manual intervention may be essential. We need good monitoring systems to catch whatever is wrong and good alarm systems to make someone aware that something urgently needs attention. I would claim that we’re quite good at setting up, tuning, and handling alarms.
When I’m not at work, I’m often sailing, often single-handedly for longer distances. Alarms are important for ... [continue reading]
make is a utility for automating builds. You specify the source and the build file and make will determine which file(s) have to be re-built. Using this functionality in make as an all-round tool for command running as well, is considered common practice. Yes, you could write Shell scripts for this instead and they would be probably equally good. But using make has its own charm (and gets you karma points).
Even this ... [continue reading]
