You may have heard, last year the global Design System team was established, and we’ve been building something that all countries and teams could benefit from. We call it Voca, and we’d like to tell you a bit more about it. TL; DR Why to use Voca…
Sometimes it is hard to be able to do things that we know are nescessary in development. There could be multiple reasons for that. Productivitiy blockers are one of them. Another is plain old time. In this post, I will describe one of the ways we use…
This article is about "the death [of productivity] by thousand cuts" -
about the many obstacles that make enterprise development unnecessarily
slow, costly, and painful. And it is about the "invisible cost" of
ignoring them. I look at the top…
Let’s be honest, starting a new job is challenging! New people, new culture, and new ways of working. I joined Telia in January this year and must admit I had my doubts about working for such a large company. Turns out, I love my job and Telia really…
A key part of implementing micro frontends is to achieve independent deployments of the individual apps. We have implemented a micro frontend architecture using Webpack Module Federation. Our system is organised in a mono-repo and we use GitHub…
After reading about SWC, and how it is supposed to be both a transpiler á la babel and a typescript compiler, while doing both blazingly fast, we wanted to check if it could improve our build times. And it really did! The details of our setup will…
Micro frontends with Module Federation This article explains how our team has implemented a micro frontend architecture using Webpack Module Federation. If you're interested in understanding why we decided to use a micro frontend approach read THIS…
Our task was to merge two existing apps, and in the same process, merge two existing teams. The existing apps were MinBedrift – an enterprise mobile self-service application – and MinPortal – an enterprise datacom self-service application. Both were…
A month ago I have started learning Rust and would like to share my impressions, the good things I have appreciated, and the things I have struggled with. Why Rust, do you ask? Primarily to challenge myself, to leave the land of managed runtimes…
So you have just deployed your Docker container to AWS Fargate but it keeps on restarting with the event "service XYZ (..) is unhealthy .." and you have no idea why. I have spent many bloody hours here and will gladly share my insights with you. The…
On a calm autumn morning we got a desperate call from our customer service. Our biggest customer had just started a pilot of our "expense share" functionality - and was missing half of their data. And they absolutely needed them for sending salaries…
When I was deciding what new language to learn, I could have picked the quite familiar Scala but chose instead Clojure - not despite of its lack of object-orientation, its immutable data structures, its too many parentheses on a single line - but…
If you call a remote REST service, you perhaps want to retry automatically upon recoverable errors. Make sure to test that code - so that you won't end up surprised that it is completely broken, as I was :-) What follows is a few simple tips for…
During our regular "tech lunch," we have got our brains blown by the talk Lucas Cavalcanti & Edward Wible - Exploring four hidden superpowers of Datomic (slides) that summarizes the key benefits a startup bank in Brazil got from using this…
I have just gone through the painful experience of troubleshooting a remote Java webapp in a production-like environment and longed for Clojure's explore-and-edit-running-app REPL. I want to demonstrate and contrast the tools the two languages offer…
In Clojure we use again and again the same data structures and have many functions operating on them. Java programmers, on the other hand, create a unique class for every grouping of data, with its own "API" (getters, setters, return types, ...) for…
As a Clojure developer thrown into an "enterprise" Java/Spring/Groovy application, I have a unique opportunity to experience and think about the differences between functional (FP) and object-oriented programming (OOP) and approach to design. Today I…
We've recently been developing a cross platform application. In its core, it is not cross-platform as in mobile versus desktop, but moreso one language intertwined with another. Let's walk through our challenges and discoveries when building this…
"It will only take about an hour," I said to her. Two days later, a pull request awaits review. Where has all that time gone? What are the sources of delay in software development and how can we make it faster? Our story (If you are in a hurry and…
We have a Java/Groovy Spring Boot webapp, mainly running a bunch of batch jobs fetching, transforming and combining data. It is challenging to troubleshoot production issues because some production APIs are only accessible from the production servers…
