Why a 24 GB GPU Does Not Give Your Local LLM 24 GB

I keep seeing the same local LLM sizing mistake: "The model file is smaller than my GPU, so it should fit." That is only the first check. A 24 GB GPU does not give your model a clean 24 GB memory budget. The display stack, runtime, temporary buffers, model weights, and KV cache all compete for the same space. Here is the worksheet I use before I download a model or rent a GPU. 1. Star...

Technical Documentation Template: Build Product Docs With a Tested Structure

Originally published at https://ninadpathak.com/articles/technical-documentation-template/. Creating documentation often forces several decisions at once: where readers begin, how they complete the first task, where exact details belong, and how they recover when a step fails. A template reduces that first pass to a structure you can inspect and adapt. I built this template to solve a narrow p...

Beyond the Black Box: Reclaiming Developer Agency in an Era of AI-Assisted Coding

Originally published on tamiz.pro. The promise of AI-assisted coding is seductive: velocity, reduced boilerplate, and the elimination of context-switching fatigue. Tools like GitHub Copilot, Cursor, and various IDE plugins have transitioned from novelty to necessity in many modern codebases. However, a subtle but dangerous drift is occurring in our development practices. We are witnessing a shift...

A backup you haven't restored isn't a backup

Migrating from MongoDB Atlas to a self-hosted replica set bought us control and cut our bill. It also quietly removed something we had stopped thinking about: Atlas had been taking continuous backups for us the entire time. After the migration, production data for Prochesta lived in /var/db/mongo on a single VPS. No snapshots. No off-box copy. A rm -rf, a bad migration script, or a dead disk woul...

ChronicleOps: Autonomous Chaos Engineering & Self-Healing Telemetry Engine published

What I Built ChronicleOps is an autonomous cloud chaos engineering, real-time observability, and self-healing platform built natively on Zerops. Instead of manually troubleshooting downtime, ChronicleOps lets developers spin up target application stacks, inject controlled fault vectors (such as process kills or container crashes), observe real-time telemetry degradation, and let the sy...

How I found a 32x performance bug hiding in a UTF-8 decoder

Last week I was profiling a Node.js service that processes large JSON-RPC responses. Three concurrent 18.7 MB responses crashed the process with an out-of-memory error — on a machine with 1 GB of heap. The culprit wasn't the JSON parser. It was the UTF-8 decoder that ran before JSON.parse ever saw the data. The setup The service fetches binary response bodies as Uint8Array and convert...

If you've already learned Git commits, branching, and merging, you've mastered the mechanics of version control. But knowing Git alone doesn't make you effective on a real engineering team. In this article, we'll cover: What Pull Requests (PRs) actually are How professional code reviews work Why .gitignore is essential The dangers of committing secrets When to use git merge vs git rebase The...

AI Can Write the Code. You Still Have to Design the System.

AI Can Write the Code. You Still Have to Design the System.

The foundation of your application is everything, especially when you use agents to write your code. Everyone talks about garbage in/garbage out with AI and machine learning, but no one really talks about what that means when you hand an LLM an entire codebase and tell it to start building. LLMs are basically just billion dollar pattern matching black boxes. If you give them a well-understood sta...

AI Engineering #02 — Chunk-First, Chunk-Native: The Unit of Work Is a Data-Model Decision, Not a Prompt-Time Patch

Previous: #01 — When an AI Discards Its Own Search Results This is a post-mortem on my own system, not someone else's. And here's the uncomfortable part: I knew the books could be enormous — it was written into the project's own goals, in black and white, before a line of code. I just didn't treat that knowledge as a design constraint. I filed it under "handle it later," built for the common cas...

On-Demand TLS: Issue Certs at the Handshake

To issue TLS certificates on demand for wildcard-DNS subdomains such as sslip.io, Temps issues each certificate lazily at the first TLS handshake instead of provisioning every hostname up front. Because the Temps operator does not control the sslip.io DNS zone, it cannot complete DNS-01 for a wildcard certificate. Pingora's certificate_callback finds no certificate, fails the first handshake quick...

Why We're Building Vertical SaaS on WordPress Instead of Building Another SaaS Platform

If you build WordPress websites for clients, you've probably encountered the same problem we kept running into. The website itself is rarely the complicated part anymore. An agency can build a very good site with WordPress, Elementor, Bricks, Gutenberg or whatever stack they prefer. The real challenge starts when the client asks for software that sits behind the website. A church doesn't just wa...

A Philosophy for AI Agents

Skills and Character When you hire a person, do you judge them on skills alone? Probably not. You care whether they are kind, generous, patient, whether they will settle into the team. Someone too stubborn, too aggressive, too much of a taker gets passed over. In hiring, character weighs as much as skill. What about AI agents? The world still picks them by benchmark scores, coding accu...

Over the last few days I have been looking at several developments around enterprise AI agents that initially seemed unrelated. Cloudflare open-sourced its internal agent workspace platform. Researchers published work on what happens when an agent authorizes an action using state that changes before execution. Enterprise AI leaders are starting to talk less about how many agents they can deploy...
