Day 54: A Volume Belongs to the Pod, and a Resource Group's Region Is Only Metadata

Day 54 of DevOps, Day 4 of Azure. Today was about where things belong, and the answer was not the obvious container in either case. A file written in one container and read from another turned out to belong to neither of them. And a virtual network in West US sat inside a resource group in East US, which turns out to be completely normal. One Kubernetes task, one Azure task. Share a volume…

Day 54 of DevOps, Day 4 of Azure, focused on the proper placement of resources and how they relate to one another. A file written in one container and read from another turned out to belong to neither container. A virtual network in West US was found inside a resource group in East US, which is normal practice. The volume's lifetime follows the pod, not the containers, and its data is safe across container crashes.

The resource group's location only stores its metadata, while the resources within can be in different regions, although it is recommended to use the same location. When a task names a region, it should include the --location flag to ensure proper functioning. Azure Virtual Networks can have overlapping IP address spaces, but they must not when peer-to-peer connections are established.

If a team creates three new networks without a plan, they risk overlap issues that could affect communication between the networks.

I built my own operating system that runs in the browser (NebulaOS)

Most portfolios are a scroll of sections. Mine is an operating system. For Hack Club's WebOS 1 workshop I built NebulaOS, a personal OS that runs entirely in your browser.

  • NebulaOS is a browser-based OS for Hack Club's WebOS 1 workshop
  • Features include window manager, apps, file system, personalization options
  • Built with React, TypeScript, Vite, and deployed via GitHub Actions

How many samples does a false-positive budget need?

Pick a detector, run it over some benign traffic, and choose a threshold. Usually the threshold is an order statistic of the benign scores — the k-th largest, or a quantile — and you report something…

  • Approximately 149 benign samples needed for 95% confidence interval of 2% false-positive rate
  • 1,000–2,000 paired attacks required to detect 2-point difference with 80% power
