When you're working with data, one of the most common things your code does is search. Let's say you have a list of users, transactions, or even just numbers. How you search through that data can make the difference between Two of the most fundamental ways to search are linear search and binary search. They solve the same problem, but they behave very differently as your data grows.
Hi everyone, my name is P Swyom Sanjog. Welcome back to my blog—I hope you’re all doing well. Today, I’m bringing a new topic: Virtual DOM. Let’s understand what the Virtual DOM is in simple terms. We’ll cover key questions like what it is, why it’s used, and how it works. So, let’s get started! Virtual Dom So, let’s break down the topic into “Virtual” and “DOM.” Virtual means something that exi
Your phone will connect to the strongest tower it hears. It does not ask for ID first. It assumes trust, and that assumption is the entire problem. I first noticed this in 2019 outside a security conference in Las Vegas. My test Android dropped from LTE to 2G for 47 seconds, then returned to normal. No user notification. The baseband logs showed a cipher downgrade to A5/0, a location area code tha
If you run Kubernetes and want a wildcard TLS cert from Let's Encrypt — say *.example.com — you need a DNS-01 challenge. HTTP-01 cannot prove control over a wildcard. That single fact rules out the easy path most tutorials show. This post is what we actually run at Hostim.dev for our shared *.region.hostim.dev wildcard. We use cert-manager for per-app certs and a plain certbot Ansible playbook for
I have been working on a .NET assertion library called Axiom Assertions. It started as a way to learn how assertion libraries work, then grew into an experiment around deterministic output, batching, analyzers, and AI-focused test assertions. The repo is here: https://github.com/spearzy/Axiom-Assertions This did not start as a plan to overthrow every assertion library in .NET. That would be a bit
I shipped mcp-probe — a CLI that points at any MCP server, enumerates every tool, resource, and prompt, calls each with auto-generated arguments, validates against declared schemas, prints a pass/fail scorecard, and exits 0/1 for CI. The plan for launch week: run it against the official Node MCP servers and post results. The first run made me look like I'd broken half the ecosystem. The second, af
Hi, we are back again. Previously, I created a simple Google Cloud VPC and then improved the configuration by introducing variables. This time, I want to continue with another Terraform concept: outputs. But, we will not be using the previous code, because adding outputs for one vpc is too simple. So, I made the lab slightly more practical. In this lab, I will create: a custom VPC network a subnet
In Part 1 of this series, I enumerated a few obstacles for engineers taking vibe coding from side projects to production. Part 2 looked at AI usage from the manager's perspective: measuring adoption, understanding the gap, coaching to fill the gap. Both of those were "Day 1" problems: getting started, getting people on board, figuring out the tools. This article focuses on what comes next: the vib
