In the previous post on Pods we saw that a Pod you create by hand, once it is deleted or its node fails. Nothing brings it back. That's fine for a quick test, but not for a real application.
This is where ReplicaSets and Deployments come in. A ReplicaSet keeps …
If you are new to Python, this output looks odd:
>>> map(str, [1, 2, 3])
<map object at 0x7f3a2c1d0>
>>> sorted([3, 1, 2])
[1, 2, 3]
>>> sum([1, 2, 3])

Three built-ins, three different kinds of result. This isn't inconsistency. Each function returns the cheapest form that can honestly …
If you are starting with Kubernetes, the Pod is the first thing to understand. Every container you run on Kubernetes runs inside a Pod. Deployments, Jobs, and StatefulSets all create Pods for you. In this post we'll cover what a Pod is, how to write a Pod manifest, and how …
A Namespace in Kubernetes is a way to divide a single cluster into multiple virtual clusters. It gives you a scope for resource names, so two teams or two environments (say dev and staging) can each have a Deployment called api in the same cluster without clashing.
Namespaces are useful …
In a relational database, a many-to-many relationship exists when multiple rows in one table are related to multiple rows in another table. A classic example is students and courses — a student can enroll in many courses, and a course can have many students enrolled in it.
Firebase Authentication is the fastest way to add a complete sign-in system to a Flutter Android app. It handles credential storage, session management, and token refresh so you don't have to. This guide walks through the full setup from dependencies to listening for auth state changes.

When you start building an app with Firebase, the first thing you reach for is Firebase Authentication. It handles sign-up, login, password resets, social logins, and session management out of the box. It's fast to integrate and removes a huge amount of boilerplate.
But it doesn't take long before you …
With the rise of "edge-to-edge" screens, modern Android smartphones come in all shapes and sizes. From corner hole-punch cameras and teardrop notches to rounded corners and folding screens, the visible canvas of a mobile app is no longer a perfect, uninterrupted rectangle.
If you don't account for these hardware and …
If you have ever built an application with Supabase, you probably know that it lets you query your database directly from your frontend code. You don't need to write a traditional backend API server (like Express or Django) just to fetch data.
While this is incredibly convenient, it raises an …
If you're building a web or mobile application with Supabase, one of the first configuration steps involves initializing the Supabase client with a URL and an API key.
However, you might notice different terminologies floating around in tutorials, official documentation, or the Supabase dashboard: Anon Key, Publishable Key, Service Role …
