Martin Atkins's latest study presents a clever technique for handling "ephemeral values" in Terraform, which are values needed during a plan but should not be stored in the state. The method helps manage dynamic or sensitive data that is only relevant for a single operation. https://log.martinatkins.me/2024/05/22/terraform-ephemeral-values/

This opinionated report argues that Large Language Models (LLMs) are not the ultimate solution for complex socio-technical problems in the SRE and operations space. It cautions against over-reliance on AI, emphasizing the continued need for human expertise and critical thinking. https://blog.relyabilit.ie/llms-wont-save-us/
