Building Arogya Seva: How I Built an Ultra-Low Latency Telehealth Voice AI for Bharat in 10 Days

Introduction: The Problem & The Mission Across rural and semi-urban India, access to timely healthcare advice is hindered by high patient-to-doctor ratios, geographical distances, and language barriers. Millions of citizens delay seeking medical advice simply because scheduling a clinic visit or understanding preliminary symptom urgency is daunting. Arogya Seva was created to bridge this ga...

I Shipped an Agent Gatekeeper (v0.1). 14 Developers Showed Me What I Missed. Here's v0.2 — a Control Plane.

Previously: I Stopped Trusting AI Agents With Tools. So I Built a Gatekeeper. — the v0.1.0 launch story (Aug 13). Code: github.com/deghosal-2026/agent-tooltrust · pip install agent-tooltrust (v0.2.0) Release: v0.2.0 on GitHub · PyPI Three days ago I shipped a gatekeeper for AI agents. The idea was simple: before an agent's tool call executes, a deterministic engine scores it across five risk di...

TwinScope — one diff tool for JSON, CSV, PDFs, folders, git refs and images. Local-first, handles large files.

As dev i need to tool to compare some file and data for my work so created this side project, please check it out and give your feedback. TwinScope compares two of almost anything — JSON, YAML, XML, CSV, PDFs, folders, git refs, images, lockfiles, .env files, saved web pages — and picks the right engine itself.

Katalon Studio has no native Allure adapter. Here's how to get one anyway.

JUnit has an official Allure adapter. TestNG has one. Cucumber has one. Katalon Studio does not, even though it's one of the most widely used test automation platforms out there. Allure-Katalon Bridge fixes that. It turns any Katalon Studio project into an Allure-reporting project by copying a handful of files into it. No plugin installation, no OSGi packaging, no command line required, and no ch...

Learning Elixir: Alias, Import, Require and Use

I like to think of the four tools in this article — alias, import, require, and use — as four different ways to reach into another drawer of the toolbox. In the previous articles I organized my functions into drawers and stuck notes on them. Now I need to use tools from other drawers, and each of these four keywords reaches across in its own way. alias is like writing a short nickname on a drawer ...

What I Learned About Exceptions in C#: Understanding Errors Instead of Hiding Them

When I started learning C#, I thought exceptions were mainly about one thing: Put the code inside try, catch the exception, and the problem is solved. But as I worked more with .NET and started building APIs, I realized that handling an exception is not the same as hiding it. This article is about what I learned while trying to understand exceptions in C# and how my way of thinking about erro...

Building the flagship (1): browser-correct cookie auth in Fitz

TL;DR — Fitz has @auth_provider / @authenticated for Bearer-token APIs, but a browser admin panel needs something different: the browser can't send an Authorization header on a page navigation or a WebSocket handshake, and an unauthenticated request should redirect to /login, not return a JSON 401. So the flagship Admin app uses a session cookie: login verifies the password with Argon2id, signs a...

I built an image vectorizer that grades its own homework — and it kept catching me lying

Every image-to-SVG converter I've ever used makes the same promise on its landing page: 100% accuracy. None of them can define what that means, let alone measure it. So I built one that does. It's called Vecline, it's free, MIT, and runs entirely in your browser. But the interesting part isn't the tracer. It's what happens when a tool measures its own output instead of asserting it's good — becau...

Serverless DevOps: When It Wins, When It Doesn't, and How to Run It

TL;DR: Serverless DevOps = running code on services that manage the servers for you, wired into CI/CD. It shines for bursty, event-driven, unpredictable traffic (pay-per-execution, auto-scaling, single-function rollbacks) and is a bad fit for steady high-volume or long/heavy jobs (where containers cost less and don't hit runtime limits). Most real systems are hybrid. Here's the honest breakdown p...

What Building a Food Menu Information Site Taught Me About Simple Web Development

When developers think about building a useful website, the first ideas that usually come to mind are complex SaaS applications, APIs, dashboards, or AI-powered tools. But sometimes a relatively simple information website can teach you just as much about web development. I recently spent time working with food-menu data and building pages around products, prices, calories, locations, and other in...

How to Compare Two Large CSV Files Without Uploading the Data

Comparing two CSV exports sounds simple until the files get large. A common situation is having an older export and a newer export and wanting to answer four questions: Which rows were added? Which rows were removed? Which existing rows were modified? Which rows are unchanged? A simple row-by-row comparison isn't reliable when the order of rows changes between exports. What you really want is...

Stop Using AI to Write Code, Start Using It to Navigate

The trap of the 'Generate' button When I first started using AI-powered editors like Cursor, I fell into the same trap as everyone else. I would write a prompt, hit generate, and watch a wall of code appear. It felt like a superpower. For the first hour, productivity spiked. By the end of the week, I was spending more time debugging subtle hallucinations than I would have spent writing ...

Zero GPU Cost and 4-Minute Daily Runs — Making Real Rain Fall on a Still Image with ffmpeg displace

A 30-minute ASMR rain video costs me nothing but electricity, and the daily job that builds it dropped from 7–8 minutes to a little over 4. No video-generation model, no GPU rental, no editing. One still image, a physics simulation of raindrops written in Python, and ffmpeg's displace filter. For context on why I built this: in my second year of university I was making ¥100k a month, stacked side...

The Quiet Collapse

There is a particular kind of professional disappearance that does not show up in the unemployment figures. The illustrator still has a desk. The translator still has a website. The session musician still owns a violin. None of them have been fired. None of them have been informed, in any official capacity, that their occupation is being phased out. Their names remain on the same freelance registe...

My checker scored one component compliant and another deviant. Neither had a rule behind it.

This is a follow-up to part four, not a new part. Part four measured my stated routing policy against what actually ran: 425 decisions, 96 deviations, $1,248.13, none of them on the main thread. Then a reader asked what happens when no rule applies. I went to measure it, and the answer was that my checker had been inventing verdicts. In both directions. The question Brian Jin, in the ...

Spec-Driven Development in the Age of AI: OpenSpec vs. GitHub Spec Kit

Originally published on labitcode.com. In the early wave of generative AI, the software industry embraced "vibe coding" — prompting an LLM in an open chat window, hitting apply, and tweaking code until the test suite or browser stopped throwing errors. For weekend prototypes and disposable scripts, vibe coding feels like magic. But when applied to production monoliths, distributed microservices,...
