The blogpost addresses the challenges engineering managers face in maintaining their technical skills amidst busy schedules. It suggests that instead of trying to dedicate a significant portion of their time to hands-on technical work, managers can leverage their team's diversity and projects to stay updated. This involves guiding team members through experimental projects, learning from their experiences, and teaching junior engineers, which helps maintain a technical edge without compromising work-life balance

The article "Autoscaling with Keda and Prometheus Using Custom Metrics in Go" on *Medium* provides a detailed guide on how to implement autoscaling in Kubernetes using Keda and Prometheus. It demonstrates creating custom Prometheus metrics in a Go application, deploying it on Kubernetes, and configuring Prometheus to scrape these metrics. The article then shows how to integrate Keda with Prometheus to scale pods based on custom metrics, such as the number of HTTP requests or product orders, ensuring dynamic resource allocation during varying traffic conditions.

The blogpost highlights potential security risks associated with automating Terraform lifecycle management. It discusses how malicious actors can exploit vulnerabilities in Terraform automation platforms, such as Hashicorp Cloud and Atlantis, by creating custom providers or using data sources to execute malicious code during the terraform plan phase. This can lead to unauthorized access to sensitive cloud credentials, compromising entire cloud environments. The article emphasizes the need for secure defaults and validation mechanisms in these platforms to mitigate such risks

In his article "TTR: the out-of-control metric," Lorin Hochstein critiques the application of the Time-to-Resolve (TTR) metric in incident management. He argues that since incidents represent periods when systems are out of control, applying statistical analyses to TTR is ineffective and does not lead to meaningful improvements.

Richard Artoul explores the distinctions between "shared nothing" and "shared storage" architectures, particularly within data streaming contexts. He highlights how shared storage systems, by decoupling data from metadata, offer enhanced flexibility and scalability compared to traditional shared-nothing models. citeturn0search0
