HTTP Early Hints (status code 103) is a powerful feature that allows servers to send hints about critical resources before the main response is ready. This can significantly improve loading performance by letting browsers preload key assets earlier.

Setting up a highly available Kubernetes cluster can be challenging, especially when dealing with nodes across different network topologies. This blog walks through setting up a K3s cluster from scratch, no IaC, with both public and private nodes, using Tailscale for secure networking, and handling common pitfalls along the way.
Let's explore how to build a resilient K3s cluster that can handle node failures while maintaining secure communication between nodes.
Typically, we correlate a service's request-handling capacity with its allocated resources (CPU/Memory). While this relationship generally holds, our recent experiments revealed some nuanced behaviors when running Go services in Kubernetes: setting CPU requests as low as possible doesn't always translate to better efficiency.
After a while of use, we started to notice that Dataloader doesn’t have a built-in API for pagination. Then, how do we solve it?
