Ledgers are the heartbeat of any financial companies, fintech or old school financial. Not the API gateway, not the mobile app, not the underwriting model. The ledger Banks have known this for centuries. Fintechs sometimes need to rediscover it the hard way. On fintech world Revolut runs multi-currency, multi-product financial infrastructure across 35+ countries. Stripe moves money and extends c
So far, we’ve seen: The model decides what to do The MCP server executes it But something is missing. Who actually connects these two? That’s the MCP client. The MCP client is: The component that connects the model and the MCP server, and manages the entire interaction between them. It’s easy to think: “The model calls the server directly” But that’s not what happens. 👉 The model only generates i
Hi everyone! I've been working on a personal project to create a desktop virtual assistant that doesn't rely on the cloud. I wanted something that felt like JARVIS but kept my data 100% private. Brain: It uses Ollama as the backend, so you can run models like Llama 3, Mistral, or Phi-3 locally.

As a developer based in Batam, Indonesia, my days often blur together as I juggle coding, learning, and keeping
This is Part 1 of a two-part series. Part 2 (coming soon): Connecting to spoke clusters from a controller using multicluster-runtime, driven by ClusterProfile. The Cluster Inventory API (multicluster.x-k8s.io) is driven by SIG-Multicluster and centered on the ClusterProfile resource. It only delivers value when something produces those ClusterProfiles. That something is a cluster manager. Today, t
When developers travel, we usually prepare the obvious things. Laptop charger. But there is one dependency that is easy to underestimate until it breaks: mobile internet. A trip to China makes this especially obvious. Not because China is hard to travel in, but because so many basic interactions are mobile-first: navigation, translation, ride-hailing, hotel communication, ticket confirmations, pay
