Monitoring the boat network with SignalK
22.10.2026 https://y-b.one/2026/10/monitoring-the-boat-network-with-signalk/
A modern boat without internet is a boat without weather, messages and half of its brains. The router sits on top of the mast where you can’t look at its lights, so it needs an eye: a Signal K dashboard that shows what the boat network is doing, and two buttons to kick the internet when it hangs.

Installing Mikrotik LAMP R16 on a sailboat
22.10.2026 https://y-b.one/2026/10/installing-mikrotik-lamp-r16-on-a-sailboat/
Marina Wi-Fi is a myth and a phone hotspot dies the moment the phone leaves the boat. So the boat got its own 5G router: MikroTik LAMP 5G R16. This is how to set it up from zero with one script that survives being run over whatever mess is already on the router.

Making a dumbest tablet a navigation device with NMEA
22.10.2026 https://y-b.one/2026/10/making-a-dumbest-tablet-a-navigation-device-with-nmea/
Used tablets are cheap and everywhere, and most of them have no GPS at all. A chart app without a position is just a very expensive paper chart. So let’s make the boat’s 5G router tell the tablet where it is, over Wi-Fi, with NMEA and a tiny container.

IV: Deploy kafka (RedPanda actually) to our k3d cluster
24.02.2021 https://y-b.one/2021/02/iv-deploy-kafka-redpanda-actually-to-our-k3d-cluster/
Actual kubernetes-native apps often communicate not directly, but by sending messages to each other. The most common messaging apps for them are RabbitMQ, Redis (despite it’s actually a caching thing) and Kafka. In this case we’ll deploy a lighter Kafka alternative — Red Panda — which is much simpler in deployment, wa-ay less resource-greedy, but fully compatible with the original Kafka protocol.
