Migrating Cloudflare to Terraform

Tue, 28 Apr 2026 14:00:00 +0530

A while back, I was tinkering in the Cloudflare dashboard and accidentally fat-fingered a DNS configuration. I didn’t realize the impact immediately, but I ended up taking down lorbic.com for an hour.

When I scrambled to fix it, I hit a wall: there was no “undo” button. There was no Git history to tell me what the record used to point to, and no review to catch the mistake before I blew it.

Python Background Workers: Architecture, Queues, and Retry Strategies

Sun, 01 Feb 2026 13:00:00 +0530

I thought processing audio in the background was simple: spawn a thread, run the script, save the file. Then I hit 200 concurrent requests, and it failed epically.

The CPU spiked to full usage because of pydub’s processing. The TTS API didn’t rate-limit me but, it was horribly slow. Then the jobs started failing. Half the jobs died silently. The other half wrote corrupted files because of race conditions I didn’t know existed. And when I deployed a little fix? The deployment killed in-flight jobs, leaving orphaned audio segments scattered across cloud storage directory.

I Added Session Management to Aider

Thu, 15 Jan 2026 20:30:00 +0530

I’ve been using aider as my primary AI coding assistant for a while now. It’s the one tool that actually fits my workflow: terminal-based, Git-native, and it works directly on my local files. No copy-pasting into web forms. No context windows that forget everything. And not waiting for agents to keep thinking.

But it was missing one thing that drove me crazy.

The Problem: Context Evaporates

Here’s the scenario. I’m deep into a complex refactor. I’ve added 15 files to the chat, built up tons of context with the model, and we’re making real progress.

Can ClickHouse Replace Vector Databases? HNSW, Benchmarks & SQL Setup

Wed, 14 Jan 2026 20:00:00 +0530

Everyone’s building AI apps now. And every AI app needs a place to stash embeddings. The instant your data grows beyond “fits in memory”, you need a vector database. Or do you?

If you’re already running ClickHouse for analytics, here’s some good news: you might not need another database. ClickHouse can hold its own as a vector store. Not because it was built for it, but because it’s built to be fast at everything.

Go Garbage Collector Mechanics: Pacer, GOGC, and Allocation Latency

Wed, 07 Jan 2026 00:21:12 +0530

In the world of high-throughput backend services, we often obsess over the usual suspects of performance: database indexing, network latency, and algorithmic complexity. But recently, while debugging our core gateway service (backend-gw), I encountered a bottleneck that defied standard logic.

The service was CPU-bound, yet active heap usage was surprisingly low (~200MB). P99 latency was spiking at random intervals, but database queries were returning in milliseconds.

The culprit was not the business logic. It was memory management. I was effectively running a Denial-of-Service attack on my own runtime.

Introducing CouchLens: A Query Analysis Tool for Couchbase

Sun, 28 Dec 2025 20:00:00 +0530

CouchLens is a client-side web application for analyzing Couchbase N1QL query performance. You feed it JSON exports from system:completed_requests, system:indexes, and schema inference results. It parses execution plans, computes metrics, detects inefficiencies, and generates a report showing where your queries are slow.

Everything runs in the browser. No data leaves your machine. The tool is a Progressive Web App, so you can install it and use it offline. The goal is to give database administrators and developers a way to understand query behavior without writing custom scripts or debugging raw JSON.

I Built My Own Google Drive

Wed, 01 Oct 2025 02:02:23 +0530

Why Bother?

Whenever I want to download a folder from Google Drive, it starts zipping it for what feels like minutes, and then it downloads the whole zip. There’s no incremental download, and I can’t add it as a network drive for obvious reasons. These limitations are frustrating, but they also got me thinking: what if I could have a solution that’s more flexible, more customizable, and truly mine?

Stealth VPN with Outline over HTTPS

Tue, 12 Aug 2025 00:00:00 +0000

What We Are Doing

If you are somewhere that blocks VPNs through deep packet inspection (DPI), SNI filtering, or crude port blocking, the goal is to make your VPN traffic look as boring as possible.
The quick win is to put it on port 443, the same port used by HTTPS. That is the lifeline of the modern web, so most firewalls are reluctant to block it.

Docker Volume Backup: The 1-Line Command You Should Be Using (Instead of tar)

Sun, 13 Apr 2025 07:14:00 +0000

How to Backup and Restore Docker Volumes Between Machines

When working with Docker, persistent data is often stored in volumes. Unlike container filesystems, volumes survive restarts and recreations. But what if you need to move this data from one machine to another?
Here’s a quick and reliable way to back up a Docker volume on one computer and restore it on another.

NGINX: Building from Source and Installation on Linux (Updated)

Fri, 02 Feb 2024 18:28:00 +0000

NGINX is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. NGINX is a free and open source software licensed under 2-clause BSD.
You can easily download and use NGINX in Windows, macOS, Linux and other operating systems link read NGINX installation instructions from the official docs and install on your operating system for free.

But, in this blog we are going to build NGINX from source code. And we will configure NGINX’s settings, paths, and add or remove modules.

How to Install Docker Desktop on Another Drive in Windows

Sat, 27 Jan 2024 13:11:47 +0000

Docker Desktop on Windows installs to your C: drive by default. When you pull large images (often 1.5GB each), add build layers, and stack containers, the ext4.vhdx file that holds all your container data bloats fast. This guide shows you how to route Docker to a secondary drive entirely, using CLI flags instead of the GUI.

Quick Start

Uninstall any existing Docker first. Then open PowerShell as admin and navigate to your Downloads folder where the installer is. Run:

AWS - Host Static Website With S3 + Cloudfront + Route53

Sun, 07 May 2023 15:14:24 +0000

In this blog I’ll discuss how to host a static website on AWS with S3, CloudFront and Route 53. We will secure our website with SSL certificate generated from Certificate Manger, enable HTTP/2 and HTTP/3 and redirect insecure http traffic to https version of the website. We will also make our bucket private and add policy to allow access from CloudFront.

Access Wsl Filesystem From Windows 10 File Explorer

Tue, 04 May 2021 00:52:26 +0530

If you want to get Linux environment in your Windows system there are some solutions that provide the opportunity.
For example MYSYS, CYGWIN and a Virtual Machine (If you want complete linux machine) or Multiple Boot.
But some of them aren’t much powerful and some are resources hungry like Virtual Machine.
So, the solution is WSL (Windows Subsystem for Linux).
You can learn how to setup WSL from here.
