Sometimes you have a server at home but you cannot reach it from outside. Maybe it sits behind a router, maybe your ISP uses CGNAT, or maybe you just do not want to open ports on your home network. This is where SSH reverse tunnelling becomes useful. It lets your home Linux machine connect out to a public server, usually a small VPS, and after that you can use the VPS as a bridge back into your home network. ...

After Tuesday’s pitches, before we all headed to the event dinner, I went looking for someone who would tell me what was wrong with ours. A founder I respect gave us twenty minutes and spent them taking apart the pitch I’d just given. It was uncomfortable in the way only useful feedback is. He kept circling back to one question I couldn’t quite answer, and the longer we talked, the more I understood that question was the whole point. ...

I attended a fireside chat with Viggo from SolvaPay and Tobias from Antler at Antler’s office, just before the National AI Startup Competition 2026 finals in Stockholm. It was the kind of conversation where you could tell the people on stage had actually been in the trenches. They didn’t sugarcoat anything, and a few lines they dropped have been rattling around in my head since. These are the couple of things I want to remember. I’m writing them down for myself more than anyone else, but if you’re starting a company, or thinking about it, maybe a couple of them land for you too. ...

As an engineer, I felt comfortable on the technical side. Writing code, building prototypes, breaking a problem into smaller parts and trying to solve it were all things I was used to. So before going into the hackathon, I honestly assumed I would be able to handle the technical side somehow. I could build something, get a working product out, and submit it by the end. But I quickly realised that building something that works is only one part of a hackathon. ...

Minikube in a nutshell Minikube lets you run a local Kubernetes cluster on your machine. For context, Kubernetes is an open-source system for automating the deployment, scaling, and management of containerized applications. Minikube, however, is lightweight, quick to set up, and perfect for testing and development. It simulates a real Kubernetes environment, allowing you to build and test applications locally before deploying them to a larger cluster. By creating a single-node cluster, Minikube helps you mirror a full Kubernetes setup. It uses virtual machines or Docker containers to keep the process smooth and simple. ...

GoFraud: Building a Real-Time Fraud Detection System in Go Music platforms process huge numbers of stream events every second, and that means they also have to detect abuse just as fast. If bots can generate fake plays, they can manipulate royalties, break trust in the platform, and turn the data into noise. I wanted to understand this problem more deeply, so I built GoFraud: a real-time fraud detection system written from scratch using Go, Python, Redpanda/Kafka, Redis, PostgreSQL, Prometheus, Docker, and Kubernetes. ...

If you ask an AI to show you a seahorse emoji, the result can be surprisingly strange. Instead of giving a clear answer, some models apologise, repeat themselves, or keep suggesting the wrong emoji. A very simple question can push the system into a strange loop. Seahorse case example from the internet The reason is that AI models learn from huge amounts of human-written text online. And many people seem to believe that a seahorse emoji exists, even though it does not. Because this idea appears so often in training data, the model may treat it as true. ...
