Language engineering and people on log verbose

Beyond Servant Leadership I’ve been reflecting on my time as Head of Platform and my leadership roles at itemis, and I’ve realized that the popular concept of “Servant Leadership” has some significant blind spots.

The Subscription Trap: Why “Just Add Billing” Fails Digital products and SaaS models have made recurring billing the default.

I was genuinely excited.

In this post, we take a look at a sample application built on top of the modelix stack during my 20% time at itemis.

Today marks the 10th birthday of the mbeddr open source project.

This year the JetBrains Meta Programming System (MPS) community has continued to grow.

What problems does Low Code solve?

Share MPS code snippets on the web as easy as text.

Today I tweeted this, rather polemic, tweet about mob programming: I think mob programming is torture.

We need platforms for models in the cloud!

After the release about a month ago it’s time for the first bigger update.

How does MPS identify languages, solutions, models, concepts, nodes, or even properties?

Getting JetBrains MPS into the browser with Projector on Kubernetes.

My thoughts on the new Projector project by JetBrains, how we can use it with MPS and how it relates to modelix.

How to scale your language engineering project beyond a single team without causing a communication and dependency hell.

For most of 2020 I was planning to create a dedicated website for my “language engineering with MPS” tutorials that I streamed on Twitch at the end of 2018 and early 2019.

In November I accidentally started a language engineering newsletter with a tweet.

Fernsprecher is a plugin for IntelliJ based IDEs by JetBrains like Meta Programming System (MPS) that makes it easy to read IDE logs in the browser.

How we tracked down a subtle JetBrains MPS generator bug after upgrading to 2019.3—property lookups failed due to constant unification missing the language ID—and contributed a one‑line upstream fix.

Is a streaming series on Twitch about JetBrains MPS.

Last year I started a stream series about JetBrains Metaprogramming System called “Heavy Meta” on Twitch.

In this post I‘m sharing some of our experiences from updating to MPS 2018.3 in various codebases.

There are a number of questions around testing in JetBrains Meta Programming System (MPS) that I get a lot.

A while back I experimented with “streaming” about MPS.

The MPS meet-up in Munich sprung some discussions about how feature branches and language migrations get along.

Today I tried something new: I streamed while I was programming.

Why do we still glorify programming like it’s an field of work that’s more like art than work?

I might be a bit late to the party since a bunch of people have already written about Slack and how awesome or awful it is.

Is a small website that tries to collect a lot of community information around MPS.

Is a set up extensions to make your life as language developer in MPS easier.

Finally it’s there the continuation of the amazing Planet Earth documentary.

While I was coding some tests for my side project I thought about if I can find a way to write my tests in a way that fits better to my way of thinking while I code.

Swift playgrounds for experimenting with Core Image CIFilters on macOS—per‑category projects for fast, side‑by‑side testing (blur, color adjustment/effect, composite, distortion)—with a GitHub repo to explore and contribute.

This is the first “real” post about my current side project.

This is the first post in a series of posts about my current side project.

Here you can find a selected list of projects I have worked on.

On Friday I gave a about two hours long introduction to F# to my colleagues at itemis Stuttgart.

I haven’t blogged for quite a while now.

I’m Kolja a software engineer living in Stuttgart, Germany.

While I was working on the trainmonitor project I need a back-end server that could handle the HTTP API.

mbeddr.arduino is a DSL to write programs for the Arduino platform.

Zugmonitor App ist ein Projekt das in meiner Freizeit entstanden ist und es ermöglicht sich über Zugverspätungen informieren zu lassen.

In the past years I have done lots of work in C# and recently came back to work with Java because I am now working in a project that involves MPS.

On Sunday I have given a talk about mbeddr and how we build it at FODESM.

After some month of low activity in the mbeddr.arduino repository I found more time to work on it in the past week.

Here is a little status update on the mbeddr.arduino project.

Good news for all debian and ubuntu users using the Meta Programming System by JetBrains: I have just created a debain package for it.

Recently I have published my Trainmonitor app, that is using a backend server to get the train data and do the notifications.

How to implement a custom serial-port reporting backend for mbeddr on Arduino: an overview of the reporting architecture (messages, tables, report statements, strategy) and generator rules for emitting messages—with and without parameters—plus counters and

As some of you might have noticed there where some recent changes in my professional life.
