Welcome to TNW Basics, a collection of tips, guides, and advice on how to easily get the most out of your gadgets, apps, and other stuff.

What is GitOps? Extending devops to Kubernetes and beyond

The last decade of programming has seen a number of revolutionary transformations. One has arisen from a cluster of practices around devops, which aligns development and operations teams into a shared work process, and continuous integration and continuous delivery (CI/CD), in which devops teams deliver constant incremental updates to a codebase. Another transformation has come from the related move from monolithic codebases to cloud-based microservices running in containers managed by orchestration platforms like Kubernetes.

Container-based applications running on clustered systems or in the cloud can be complex and difficult to provision and manage, even with a

The evolution of iPhone screen-to-body ratios — shown by our sexy-ass graph

Last week, I put together a piece about the rising size of iPhone screens. It was, in summary, a graph showing them getting bigger. Surprise!

But as the week progressed, I thought about it a bit more and had another thought: what about the evolution of iPhone screen-to-body ratios?

If you don’t know what this is — although the name should give you a very big clue — screen-to-body ratio is a number that shows (roughly) what percentage of the front of a phone is screen, compared to, you know, not screen.

Learn how to build a website the old-fashioned way with this HTML and CSS primer

TLDR: This Responsive Web Design Essentials course focused on HTML and CSS is the perfect coding introduction for new web creators.

Back in the old days, serious web coders used to do the equivalent of walking barefoot through the snow three miles in both directions to get a website build finished. Nowadays, these young whipper-snappers just use their website building apps and spit one up in a hour. Of course, these kids today don’t actually know how a website is really built. They just click and drag their way to a finished product.

Of course, if something goes wrong or
