Python Best Practices for a New Project in 2021
Intro The goal of this tutorial is to describe Python development ecosystem. It can be helpful for someone coming to Python from another programming language.
They say that you should stick to algorithms and data structures, that you can learn a new language…

Cheat Sheet on Curl Performance Metrics: how to benchmark server latency with curl
The ultimate guide and cheat sheet on what each curl latency metric means. Especially time_pretransfer which is extremely unclear.
Mitogen for Ansible is a completely redesigned UNIX connection layer and module runtime for Ansible. Requiring minimal configuration changes, it updates Ansible’s slow and wasteful shell-centric implementation with pure-Python equivalents, invoked via highly efficient remote procedure calls to persistent interpreters tunnelled over SSH. No changes are required to target hosts.
The extension is considered stable and real-world use is encouraged.

Kubernetes Single Sign On - A detailed guide
In this series of posts we cover how to setup a comprehensive group based single sign on system for Kubernetes including the kubectl cli, any web application with ingress, a docker registry and gitea. We'll cover most of the common SSO models so adapting what's here to other applications such as Gitlab, Kibana, Grafana etc is simple.
The full solution uses Keycloak backed by OpenLDAP. OpenLDAP is required for the Gitea component, but can be skipped for the other components, including OIDC based SSO for kubectl.
