I was solving the classic problem of calculating the widest binary tree level - essentially finding the maximum width of in the tree. I had doubts around how left and right indices of nodes is calulated because I thought we use the standard formulas for calculating indices: left := 2i + 1

Why nslookup works but ping says “Name or service not known”? Let’s get basic terminology straight up — and it’s assumed you already understand how DNS resolution works. In my quest to understand how tools like nslookup and ping behave differently, I was honestly confused by the terms DNS

In my experience, I've revisited this topic multiple times — and every single time, I’ve learned something new. So here’s a simple visual walkthrough for those who want to understand what really happens when you type a domain name into your browser. We’ll break this into

Primitive Types Primitive types (also called basic types) are the simplest, fundamental data types that aren't composed of other types: * Numeric types: * Integers: int, int8, int16, int32, int64, uint, uint8, etc. * Floating-point: float32, float64 * Complex: complex64, complex128 * Boolean type: bool * String type: string These types store their values

In my current organization, I wrote a helper script long back to organize and set up Kubernetes contexts across multiple GCP projects and environments, with custom naming based on cluster labels. I also created another script to handle all EKS clusters across AWS regions using a specified AWS SSO profile.

We’ve been building gokakashi in Go for a while now, and we had this wild thought: “What if users could define their own evaluation conditions on top of the scan reports?” Something like this in the config file: check: condition: | sev.critical > 0 || sev.high > 0 &

This is how I finally made sense of interfaces in Go. There are countless resources out there, but fails to simplify how to grasp and implement interfaces effectively, atleast for me. While observing my niece one day (toddlers can be surprisingly inspiring!), an analogy clicked in my mind. Let me

Bits are simply 0s and 1s and that's all the language our machine understands. But in larger picture how do we understand this when we are programming? Trying to troubleshoot production system? 8 bits = 1 byte * Bit: The smallest unit of data in computing, representing either a 0
