Kicked Off = we have to stop for some technical reasons that are further unspecified, and everyone has to leave the train because we are driving now in the opposite direction. a replacement bus is coming. Once every hour. With a capacity of 8 people. In some cow village 50km far away from the next city. With no cab service available. Thats was what i meant

What facts are missing in your opinion?


I know how sketchy it sounds, and it was even documented in DB Navigator. But DB makes this information inaccessible a couple of days later in the app, so there is no way to „proof“ it except asking DB itself.


Just to be sure: your blog post mentions 24.12.2024 - did you mean 2025?

Is this the right connection?:

The RE5 seems to be operated by National Express, not Deutsche Bahn, right? (but DB InfraGo is most probably responsible for the routing)


Yes it is! And yes it was a typo! Thank you for finding the link to it. I was trying to find it before but couldn’t find it in official sources, DB deleted it from the official app. It did not stop at Troisdorf though.

It is operated by National Express, but I guess the routing comes from some other company (likely InfraGo)


Well I’ll be damned, I’ve really seen it all, OP sorry for doubting w


The cacio e pepe paper posted here a couple of months ago won it in the category of physics: https://pubs.aip.org/aip/pof/article/37/4/044122/3345324/Pha...


I cooked cacio e pepe a few times over the past few months specifically because I saw it on HN there! It's delicious. Try it!


Me too! That’s why I found it so exciting to find it as IG Nobel Prize Winnder!


Hey guys, Jeremy from UMH (www.umh.app) here. We are OSS as well and focus on data infrastructure for manufacturing. Let me write you guys via Discord to get in contact


Agreed! See also the ahrefs example


The article was originally intended at manufacturing companies, not at IT startups, that currently go "all-in" on AWS and Azure with all of their managed services, when actually 95% of their workloads are in virtual machines, and the remaining stuff could easily be handled on a single VM. Or maybe a couple of VMs and a managed postgres somewhere (e.g., maybe even at AWS or Azure).

Would probably give them way more budget in actually building applications than running the infrastructure.

Maybe I'll extend the article to include the point of using a managed postgres at AWS / Azure / fly.io, whatever, in combination with Hetzner VMs.


Hetzner does start at a much lower price point, and has servers also in Singapore and US (but only since a couple of months)


Check out https://learn.umh.app

We have a lot of free info material on the topic of IT and Industrial Automation including Shopfloor KPIs like OEE. And the project behind it, is even open source.

Disclaimer: I am the CTO


Maybe this is not relevant for all industries, but in our experience in manufacturing it is for most companies an immediate no-go. Because these companies are not interested in using the open-source variant, they want to partner up with the company behind it. And in the case of EMQ, this is additionally quite difficult to pinpoint with whom one will be conducting business with.


I work in a very very (very) similar area to yourself, we should talk one day.

Still not sure I agree, Node-RED for instance is open-source, has no office and the lead developer often develops it streaming on twitch from his home in the Uk. Yes Flowforge are building to offer enterprise support. But we both know and you have written about how Node-RED is eating OT/IT. Both of our offices for instance are in a shared, but different innovation building.

I do find it interesting and misleading, that EMQ X has the line about its innovation centre. And it does perhaps make me think twice about the enterprise support offered.

Just not sure an Open Source project should be ignored because of it.

Interesting post regardless.
