My IndexNow submissions returned 202 for two weeks. None of them worked.

I have a small static site on GitHub Pages. It is served from a project subpath: https://shantj.github.io/sproutguard/ Twelve times over about two weeks, I pinged IndexNow to get the pages crawled. Every single time I logged a success, because that is what came back: api.indexnow.org -> 202 bing.com/indexnow -> 202 yandex.com/indexnow -> 202 Twelve rounds later, site:...

5 Practical RAG Challenges and How to Mitigate Them

Retrieval-Augmented Generation (RAG) sounds simple on paper: embed your documents, retrieve the relevant chunks, stuff them into a prompt, let the LLM answer. It works great in a weekend demo. Then you ship it, real users start typing real questions, your knowledge base grows past a few hundred documents, and suddenly the "simple" system starts hallucinating, retrieving the wrong chunks, or timin...

The Phone Behind the Flour Sacks: How a $0 Camera Cleared the New Hire Everyone Blamed

The register came up short on a Friday, and by Monday everyone on the schedule had already decided whose fault it was. Marisol ran a small bakery — six tables, a case of morning pastries, a back room that smelled permanently of yeast and cinnamon. She'd opened it with her late husband's insurance money and eleven years of stubbornness, and she knew the arithmetic of the place the way she knew the...

Why I Built a Zero-AI, Zero-Algorithm Q&A Space for Distraction-Free Thoughts

Have you ever opened social media, scrolled for 30 minutes, and closed it feeling even more drained than before? Between AI-generated slop, rage-baiting algorithms, and endless ads, the internet often feels less like a space for connection and more like a loud, neon-lit casino. A few weeks ago, after feeling overwhelmed by digital noise, I decided to code a small, quiet, dark-themed Q&A corn...

An AI agent can pick the model, set the parameters, and fetch the clip. It still can't decide which take belongs in your film.

I got tired of managing AI API keys, so I built Yantra AI

Every time I wanted to experiment with a new LLM, the process looked like this: Create another account Add another billing method Generate another API key Learn another pricing model Change my code Hope the provider doesn't go down It wasn't hard—it was just repetitive. As an indie developer, I wanted to spend time building products, not managing AI providers. So I built Yantra AI. What is Yantra...

Helm Values Staging vs Prod: 3 Mistakes That Broke Uptime

Originally published on kuryzhev.cloud Context We had a single Helm chart deploying roughly 15 microservices, split across staging and production, with ArgoCD 2.9 syncing everything from a monorepo. The pattern looked textbook: one values.yaml as the base, then a values-staging.yaml and a values-prod.yaml to override whatever was different per environment. On paper, this is the recommended ...

AI-Assisted Engineering: Faster to Build Isn't Cheaper to Own

I like AI coding tools. I use them myself, and my teams use them too. That is probably the most important thing to say up front, because I do not mean this as an anti-AI post. The leverage is real. Scaffolding is faster. Boilerplate is cheaper. First drafts come together much more quickly. People get unstuck faster than they used to. I have seen tasks that used to chew up half a day shrink to t...

How I Fixed Broken Portrait/Landscape Gallery Alignment (and Open-Sourced It)

Why I Built a Responsive Image Strip Gallery (and Published It for Every Framework) A few weeks ago I ran into a layout problem that sounds simple on paper: put portrait and landscape photos in the same row, aligned, without cropping them into ugly square boxes. It turned out that no gallery — not Squarespace's built-in options, not the popular npm galleries — actually solves this clea...
