The work around RegreSQL led me to focus a lot on buffers. If you are a casual PostgreSQL user, you have probably heard about adjusting shared_buffers and followed the good old advice to set it to 1/4 of available RAM. But after we went a little bit too enthusiastic about them on a recent Postgres FM episode I've been asked what that's all about.

Buffers are one of those topics that easily gets forgotten. And while they are a foundation block of PostgreSQL's performance architecture, most of us treat them as a black box. This article is going to attempt to change that.

I think the entire DevOps movement was a mighty, twenty year battle to achieve one thing: a single feedback loop connecting devs with prod. On those grounds, it failed.

Creative ideas for speeding up queries in PostgreSQL

This write-up presents a pure Terraform framework where 50+ teams deploy infrastructure using simple tfvars while platform teams maintain reusable building blocks. It highlights native lookup patterns, automated PR updates, and significant boilerplate reduction without adding preprocessing layers.

This article introduces tfplan2md, a tool that converts Terraform JSON plans into clearer markdown summaries for pull request reviews. It focuses on making plan output easier to understand in Azure DevOps and GitHub workflows.

This article explains why OpenTelemetry no longer recommends the batch processor for production durability-sensitive pipelines. It compares in-memory batching with exporter-level persistent queues and shows how the newer approach improves recovery during collector restarts.

This blog post is a comparison of personal, accessible, cloud backup options.

Tuckr is a dotfile manager inspired by Stow and Git. Tuckr aims to make dotfile management less painful. It follows the same model as Stow, symlinking files onto $HOME. It works on all the major OSes (Linux, Windows, BSDs and MacOS).

Tuckr aims to bring the simplicity of Stow to a dotfile manager with a very small learning curve. To achieve that goal Tuckr tries to only cover what is directly needed to manage dotfiles and nothing else. We won't wrap git, rm, cp or reimplement the functionality that are perfeclty covered by other utilities in the system unless it greatly impacts usability.

Yoke is a Helm-inspired infrastructure-as-code (IaC) package deployer designed to provide a more powerful, safe, and programmatic way to define and deploy packages. While Helm relies heavily on static YAML templates, Yoke takes IaC to the next level by allowing you to leverage general-purpose programming languages for defining packages, making it safer and more powerful than its predecessors.

Korrel8r is a rule-based correlation engine that automatically discovers and graphs relationships between cluster resources and observability signals across multiple data stores, enabling unified troubleshooting experiences.

Lynq Operator is a Kubernetes operator that automates database-driven infrastructure provisioning. It reads data from external datasources and dynamically creates, updates, and manages Kubernetes resources using declarative templates.

This is a docker container intended to run inside a kubernetes cluster to collect config maps with a specified label and store the included files in a local folder.

PostgreSQL Operator to create Databases and Users across multiple engines

Kubectl exec does not provide any kind of audit what is actually done inside the container. Rexec plugin is here to help with that.
