"Mutation is the key to understanding the mystery of evolution. The path from the simplest organism to the dominant biological species takes thousands of years. But every hundred thousand years, there is a sudden leap forward in evolution" (Charles Xavier, X-Men, 2000). Leaving aside all the sci-fi elements present in comics and films, Professor X's words hold a grain of truth. The development of […]
Cloudflare has prepared a module to provide support for the HTTP/3 protocol in NGINX. The module is built as an extension over Cloudflare's developing quiche library, which implements the QUIC transport protocol and HTTP/3.

When building a CI/CD process using Kubernetes, there can sometimes be a compatibility issue between the requirements of the new infrastructure and the application being migrated. Specifically, at the application build stage, it is essential to obtain a single image that will be used across all environments and clusters of the project. This principle is at the heart of what Google considers proper container management (this has been mentioned multiple times, and […]
