Why DevOps Engineers Need Practical Tutorials, Not Just Theory DevOps has become one of the most practical areas in modern IT. It is not enough to understand what CI/CD, Docker, Kubernetes, Terraform, Linux, or cloud infrastructure mean at a high level. Engineers also need to know how these tools wo
Originally published on rikuq.com. Republished here for Dev.to's readers. Google's May 2026 AI search guidance settled one debate: for Google's surfaces, AEO and GEO are "still SEO." Same crawl, same ranking, same E-E-A-T factors. Optimizing for AI Overviews is optimizing for Google search, period.
In metric collection systems, cardinality is a critical concept for balancing performance and cost. I have prepared a 4-step guide on how this balance is established in the real world. In this post, I will explain what metric cardinality is, why it matters, and how we can find the right balance in o
Most of the time I'm signed into my work Docker Hub account, and that's fine. Almost everything I build ends up there. Then one weekend I was playing around with openruntimes/orchestrator, an orchestration service for running containerized workloads with callbacks. I had a PR open with some small tw
Honest framing first: mk-qa-master is an open-source MCP server for QA engineers. The reCAPTCHA solver in it is a Tier 3 fallback for testing your own apps when Tier 1 (Google's official test keys) and Tier 2 (feature flags / IP allowlist) aren't available. It is not a "beat captcha" tool. It refuse

You hit "Submit Order" and the network drops mid-request. Did the charge go through? Should you retry? Without idempotency keys, you're gambling — and your users are the ones losing money. Idempotency is the property that making the same request multiple times has the same effect as making it once.

I see a lot of claims about which model is "best." Best at what? For whom? At what cost? I got tired of guessing. So I ran my own comparison. The setup Code generation (120 queries) Document summarization (150 queries) Question answering (180 queries) Creative writing (50 queries) I ran each query t
Most file converters upload your files to a server. I wanted to see how far I could get without one. Turns out: all the way. import JSZip from 'jszip'; import { Document, Packer, Paragraph } from 'docx'; // 1. Crack open the .pptx (it's a zip) const zip = await JSZip.loadAsync(file); // 2. Walk each
After 3 months of solo development, 15,000+ lines of code, and countless iterations, I'm excited to share MGZon - a developer portfolio platform where every profile has its own AI bot. Feature LinkedIn GitHub MGZon Profile-specific AI Bot ❌ ❌ ✅ Visitors can ask the AI ❌ ❌ ✅ AI answers from real prof
This is a submission for the Google I/O Writing Challenge I came into Google I/O 2026 expecting the normal AI announcement cycle. A faster model. A better demo. A few benchmark charts. Someone saying “agentic” at least 40 times. And yes, we got a lot of that. But one thing genuinely stuck with me: G
Every developer using AI tools knows this pain. You open ChatGPT or Claude, excited to solve a problem, "It's a Next.js app with MongoDB..." By the time the AI actually understands your codebase, I got frustrated enough to build something about it. AICodeBridge is a free VS Code extension that analy
I spent the past week building tokens on Solana. Not wrapping existing ones, not swapping — actually creating token mints from scratch, attaching economic rules to them at the protocol level, and watching a blockchain reject a transaction I told it to make. This post walks through what I built, what
This is a submission for the Gemma 4 Challenge: Build with Gemma 4 TL;DR: Vitreus is a spreadsheet agent that lets you ask natural-language questions of CSV and XLSX workbooks, then uses Gemma 4 to return an auditable JSON action manifest. The manifest can highlight rows, write values, and add formu
"react vs vue vs svelte vs solid-js — who's actually winning?" This tool answers it. Fetches daily downloads from api.npmjs.org (CORS-enabled, no auth) and overlays up to 6 packages on one inline SVG chart. No chart library. ~300 lines of vanilla JS. The scale + tick math is pure and gets 17 unit te
I think AI is starting to fundamentally change what strong engineering looks like. And honestly, I don’t think the biggest shift is coding speed. It’s ownership. Because writing code is becoming dramatically cheaper. But deeply understanding the problem, the customer, the tradeoffs, the scope, and w
Picture this. It's a Tuesday evening. Half the students are in the room. The other half are little rectangles on a Zoom call, cameras off, maybe paying attention. You're 40 minutes into a live SQL workshop, things are actually going well, and then one student, trying to be helpful, runs this: DELETE
A developer stares at a red CI. They have two options: the test is wrong, or the code is wrong. They pick one in less than a second. It's a prior they almost never name. A week ago I wrote a rule for myself: when a validator complains about the same failure twice, fix the validator. Two days ago the
