Executive summary

This blog describes briefly the most commonly used annotations of the code generation tool Lombok which shields the Java developer from having to generate or write so called ‘boilerplate code’.

These annotations are grouped after function such as object creation, field access, some methods ... [continue reading]

This is my concluding post in a series of three posts.

• The first blog post contains my general thoughts on time tracking.
• The second blog post compares different time-tracking software.
• When writing this last blog post I’ve been using Timewarrior together with ActivityWatch, Waybar and some home-brewed scripts to track my time as good as I could for a couple of months.

Executive summary

In this blog post I’ll give ... [continue reading]

I’ve considered time tracking and I’ve tested several software solutions. Perspective matters - I’m a systems administrator, I prefer doing things through the command line, and my favorite programming language is Python. My recommendations will be biased. I also feel strongly about open source and free software, and I want full control of my own data. Solutions where I cannot download the source code is not considered, same if I need to send my data to some “cloud solution”.

Someone asked/told me “What time tracker software do you use? I use hamster, and would recommend that”. This caused me to fall into a deep rabbit hole, looking into hamster and other time tracking software. I started documenting my journey, and I will compile it into three blog posts:

• This blog post contains my general thoughts on time tracking.
• Next blog post compares different time tracking software.
• Last blog post will tell detailed experiences from using ... [continue reading]

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.

Introduktion

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.

Summering

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 setup

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]
