Teaching Kids Programming: The Roblox Adventure
Martin started a Roblox game development project with his son during the holidays, using it as an opportunity to teach both programming and proper AI usage.
Building Consistently
āWe use the holidays to build this game and consistency is key. We are on it every day and right right now we have a pretty cool game. So itās really progressing and my son is really getting fast at building Roblox. Itās crazy to watch this really amazing.ā - Martin
Teaching AI Interaction
āI really use this to teach my son how to use AI. We are using heavily Claude Code and we regularly run into token limits but thatās perfectly fine. But itās really a good way to teach the kids how to use this. My son for example always tries to be kind, always tries to put smileys into the chat. And Iām really teaching you donāt have to do this. This is a machine. Itās not a human. So really itās a machine. Itās a stupid machine. It does exactly what you tell it to do.ā - Martin
Critical Thinking with AI
āFor me itās really important that he understands okay this is not a human thing. This thing is just a machine. Whatever it tells you itās not granted to be true.ā - Martin
Adamās perspective on abstraction levels:
āEven back then we always jumped in at the abstraction layer that was the most accessible understandable or relatable level. Some people that decided to tinker with electronics might start programming from a different perspective than someone that just went in looking at software only.ā - Adam
Adamās Maker Journey: Accessible Technology
Adam shares his exploration of maker culture during the holidays, discovering how accessible hardware projects have become.
The Bamboo 3D Printer Discovery
āThe bamboo printer I got, which is the smallest one, is incredibly fast. It can work online or offline. Itās $300. Itās nothing. And you can design and make whatever you like. I was so surprised because I got my son a 3D printer years ago and was extremely expensive, much slower. Now the bamboo printer was a huge success.ā - Adam
Why it matters:
āIt just works. Itās not like setting up a Raspberry Pi. When you get a Steam Deck to play video games, you plug it in and itās ready to go. If you have a Steam account, you start playing games, thereās nothing to do. But itās running Arch. Itās running one of the most customizable rolling distributions that you can have. So itās all about the packaging.ā - Adam
FreeCAD: The Event Sourcing of Design Tools
Adam discovered FreeCAD and immediately recognized its connection to event sourcing principles.
āIāve discovered FreeCAD which is open-source drafting software. Their latest version 1.0 thatās stable but thereās a 1.2 thatās being worked on replaces the commercial products. Itās much like Blender and like Open Office and LibreOffice are replacing Microsoft Office.ā - Adam
The event sourcing connection:
āItās very related to event sourcing because it is your set of events that you can play around with such as extruding a wall, attaching the other walls to it, drilling holes. Theyāre all sequential things. And if you make a change in something thatās first in line, itāll have effects on the other pieces. So itās quite fully fledged.ā - Adam
Non-destructive workflow:
āIt is non-destructive stepwise. You can look at all of these pieces that Iām creating and I see that they relate in time in history what happened before. And so thatās why I really fell in love with it. Itās like oh this is so close to event sourcing. Iām really enjoying this for some reason.ā - Adam
Practical Projects
Adamās plant pot project:
āI really want to understand I have a couple of hobbies so the plant stuff is one so Iām doing some water sensor level stuff there. Iāve been playing with capacitor circuits. The oscilloscopeās great if youāre doing any frequency stuff and itās so accessible these days.ā - Adam
The solution:
āI basically used FreeCAD to design some schematics. They will have a little reservoir around the bottom, but then the regular soil and everything immediately pops out and goes back out. So you can have the most soil and surface area at the top while still preserving a little pool of water underneath.ā - Adam
Accessibility of Modern Tools
āYou go to Amazon, thereās some really good deals but even AliExpress, itās incredibly inexpensive to get into this stuff. Getting breadboards, getting the chips with the different logic gates on them and just put them in the breadboard and itās really fun actually to have AI help you along with that.ā - Adam
The oscilloscope surprise:
āI was just really surprised as to the affordability of an oscilloscope and how small they are because the one that I got doubles as a multimeter. It has an oscilloscope built in. So when I saw I remember oscilloscopes from when I was going to school. You need a desk space for that thing. This thing fits in your hand. Itās like this big.ā - Adam
Martinās Raspberry Pi Projects
Martin set up a Raspberry Pi cluster during the holidays.
N8N Automation Cluster
āI have a few Raspberry Pis here to work on and what I want to do with them is just I set up an N8N cluster, which is automation. It just allows you to automate things. And Iām just playing around what is possible with this. You can run this on the Raspberry Pi. Itās completely free.ā - Martin
The reality:
āI basically set up the cluster. Itās running but I didnāt do anything with it. So the game in Roblox takes up all my time right now.ā - Martin
Linux Setup Challenges
āJust setting up those Raspberry Pis. I had a few Raspberry Pis a few years ago, but these were Raspberry Pis too. So that you cannot do a lot with them nowadays. So I bought a few Raspberry Pi fives and you need to set them up. Just all these Linux commands you need to set up a Raspberry Pi correctly. I couldnāt remember that. AI helps you. All the firewall stuff, SSH, making sure you have the SSH daemon running.ā - Martin
Looking Forward to 2026
Both hosts share their ambitious plans for the new year.
Martinās All-In Commitment
āA lot will change for my company in 2026. Iām looking to grow it. Iām looking to drive event modeling in Germany and over Germany. A lot of things are planned, a lot of things are coming and Iām really looking forward. I am all in. I am really all in. There is absolutely either this works or nothing works. So there is no plan B. This is what Iām doing and I will stick to it.ā - Martin
The Tooling Game-Changer
Martin on the biggest blocker:
āThatās the one thing Iām looking forward to most in 2026 getting the proper tooling ready. That will enable much more companies to adopt event modeling. Miro is currently the biggest blocker. I see many companies would love to try it but they canāt use Miro for one reason or the other or simply they donāt trust Miro because itās just a foreign company. There are many reasons.ā - Martin
The problems with Miro:
āThere is no versioning. You canāt have everything in Miro. Itās just a whiteboard and stuff like that. I get that. I fully get that. Thatās why Iām so passionate about this new tooling if itās ready. So much potential. Thatās the one thing Iām really looking forward to most in 2026.ā - Martin
Adamās focus:
āFor me the focus is event modeling first. I think thereās a lot of projects out there that either I mean you have event catalog, you have all these other things. Theyāre very niche or technical. I donāt think thereās something really out there thatās built for event modeling first. Thereās a sweet spot in the middle where event modeling needs to be and I think this is the place to actually do it.ā - Adam
Lowering the Entry Barrier
āCurrently the entry barrier is still far too high. If you start with event modeling with your team you have this empty Miro board and you have no idea where to start. There are all these elements. I mean event modeling is simple but if you have no idea what to do itās still too hard to get started and this is what we exactly tackle when we bring the tooling.ā - Martin
Adamās Book Progress
āThe book is on its way. Taking a break because I have the ghost writer helping me finish the book. Thereās a small break of course, but thatās still in plans to have the handbook out as soon as possible because we want the answers kind of there for someone to get.ā - Adam
Why now is the right time:
āIām really happy that this is the time for the book and the booklet to be coming out is that itās based on taking in what the community really needed from the practice.ā - Adam
Event Modeling.org Updates
āWe need to have that modern version of event modeling to be on the front page, keep the original article as an archive. So thatās something that will be worked on. So Iām really excited.ā - Adam
Investment and Incubation
āIām always interested in helping projects that are event modeling, event sourcing. Eventually the goal is to make Adapted Group a VC company or an incubator company that has its own funds and then can create an investment fund that people can participate in of a mix of projects that are working with an advantage because they are event modeling and event sourcing.ā - Adam
The Power of Simplicity
Why Event Modeling Works
Martin on alternatives:
āI saw a lot of these event modeling clones coming up all a little bit different with different names. Whenever I ask almost always itās like okay they didnāt really understand event modeling or they did not even try. Changing it always comes with a cost. Almost always it gets much more complicated.ā - Martin
The core insight:
āEvent modeling works because itās so simple. Thatās the only reason why itās so powerful. Thatās the reason why Iām using it. I like simple stuff. I like things that are simple. Whenever you introduce new concepts, it gets more complicated.ā - Martin
Proven Over Time
āThere is a reason why event modeling is like event modeling. You work with it for what 10 years until you made it a thing. It didnāt come from nowhere. It came out of practice.ā - Martin
Event Modeling as a Constant
Adam reflects on a decade of consistency:
āI was afraid of another methodology coming out or something technically better for event sourcing or something else. Maybe something could disrupt it. Maybe not enough people would like event modeling. And every year the answer was no, there isnāt anything. And it was more important the last two years as all of the advancements happen in AI that that hasnāt changed event modeling either.ā - Adam
The stability advantage:
āThat change and the flux within the industry is something that strengthens event modeling because it becomes something you can actually depend on being there for you. I canāt depend on the React framework because I know that itās potentially going to be changed by Vue.js or something else. Thereās very few things like that in the industry that you can hold on to.ā - Adam
The FreeCAD Analogy
Adamās powerful comparison:
āEvent modeling is FreeCAD for your business. If your business was you know an engineering firm producing something to produce, you could do it with CRUD or draw.io or draw those things manually, but I think you would quickly come to a conclusion that you need a tool. Event modeling is the FreeCAD equivalent. Itās really something that gives you the structure and the constraints.ā - Adam
Constraints as Features
āConstraints are number one thing youāll do in FreeCAD if youāre using it because you cannot use your sketch until itās fully constrained. Thatās an engineering thing. You have to make sure all of thereās no freedom of movement to any of the edges. You have to have the measurements, you have the equals, you have the angles specified. So now itās a solid drawing and then you can move to the next part.ā - Adam
The event modeling parallel:
āItās very similar to the mindset that you have in event modeling with the information completeness. You donāt have youāre not fully constrained like you have this screen thatās showing this information, but you donāt have a source for the information. Itās not fully constrained.ā - Adam
Supporting the Community
Important Call to Action
Adamās message:
āIf you are looking at the listing of the podcast, thereās a link for a GoFundMe page to help out one couple of kids that are in a real bad situation that Martin directly knows. So we never ask for anything from you. If youāre enjoying Martinās book, if youāre enjoying these podcasts, if youāre getting help from us in any way or the event sourcing, event modeling community, this is the one time that it would be a good idea to donate some money for a really good cause.ā - Adam
Martin adds:
āSmall amounts are very appreciated. Any amount of money or share of the link would always be appreciated.ā - Martin
The Year Ahead
Martinās Experience
On returning to help people:
āEven though I might have taken a break over the holidays and I have people I havenāt talked to about their projects for maybe a year, I know I have one question, one person that said, āHey, can we have another conversation about event modeling and event sourcing?ā And I know I helped them with a problem last year. Iām not afraid of what changes happen to that project because I know theyāre using event modeling and event sourcing.ā - Adam
The confidence it brings:
āI feel like Iām not walking into a minefield of unexpected stuff. When I know that person is working on event modeling and event sourcing, Iām like, āYeah, give me whatever problem you have. Iāll help you because I know what to expect. I expect to see slices. I expect to see this propagation of information left to right.āā - Adam
Fast solutions:
āI know I can very quickly with them zoom into that problem area and get going on understanding the problem and creating a solution like within that hour. Iām not going to need to take stuff home and study it and come back to them. We could right there navigate the solution.ā - Adam
Martinās Common Experience
āI had this so often this year. People come to me with problems. Oh, we need your help. Okay, letās have a quick call. Letās take an hour. Itās for free. Letās take an hour. I just help you. Okay, we sit down. We model this. And after this hour, the problem is gone. We solved it. Okay, thereās okay, you donāt have to pay me. There is no contract. Your problem is solved. Have fun. If you have a bigger contract, come back to me. Iām happy to help.ā - Martin
The Decade of Event Modeling
Adam reflects:
āI think itās a really nice base to start the next chapters to get even more refinement in the approach like the build the tooling thatās needed and all these other things. There may be like BPMN and value stream analysis, these may just be little filters on top included as add-ons to event modeling.ā - Adam
Looking at FreeCADās ecosystem:
āI look at FreeCAD and I see all the add-ons that are there. And you can use FreeCAD with no add-ons and itās great. I could I made my designs for the things I mentioned. But the fasteners I can just add the regular screws and nuts and bolts. I donāt have to make those from scratch. Thereās an add-on that gives you those.ā - Adam
The vision for event modeling:
āI see BPMN as one of those things. Okay, youāre not going to make your own. Youāre going to need something that you donāt have or you donāt want to make. Sure, thereās a BPMN analysis. Hereās given this event model. Hereās your BPMN diagrams for better or worse. Look at those if you want, but youāre not going to hand the BPMN diagrams to your developers.ā - Adam
