I added autonomous AI agents to my self-hosted Docker platform — here's what Level 1 vs Level 2 autonomy actually means

Managing a Docker ecosystem manually doesn't scale. Not because the tools are bad — Docker is fine, Compose is fine — but because the cognitive load of watching six services across multiple hosts adds up fast. You miss things. A container dies at 3am. A CVE sits unactioned for two weeks because you were heads-down on something else. An SSL cert expires because the renewal check was a cron job you ...

Most Apps Are Slower Than They Need to Be — Here’s Why (Live Demo🛸)

We’re a quarter into the 21st century, and the browser has quietly evolved into something much more than just a UI layer. It can run complex computations, leverage the GPU, process audio, simulate physics, and even run machine learning models. And yet… most of the time, we still treat it like a tool for forms and dashboards. I wanted to show what happens when we actually take advantage of what th...

Why My S3 Backup Setup Broke: Buckets, “Folders”, and Scheduling Misconceptions

Another lesson in building reliable systems - not just configuring them. I thought I had everything set up correctly. Backups configured S3-compatible storage connected Backup triggered via cron jobs during testing And yet nothing showed up where I expected. What looked like a simple configuration issue turned out to be a wrong mental model of how S3 actually works. This post breaks down...

Designing the Morpho album artwork

Matt and I have been creating artwork for his music for almost 12 years now. It’s a collaboration I’m immensely proud of, and one that offers a welcome change of scene from my day-to-day job of designing and building websites. Morpho, released on Sound Records in November last year, is our most recent project. Our 12th vinyl release and the 1st Matt is releasing using his last name, Benyayer, inst...

The ultimate utility library for Indian Web Developers

The Ultimate Utility Library for Indian Developers: ind-utils-pro 🇮🇳 If you are building an Indian Fintech app, an E-commerce platform, or any registration form, you know that validating identifiers like PAN, GST, Aadhaar, and IFSC can be a real headache. Searching for the right Regex and testing it every single time is incredibly time-consuming. To solve this exact problem, I created ind-utils-...

LangChain vs LlamaIndex in 2026: What We Actually Use and Why

Every time we start a new AI project, someone on the team asks whether to use LangChain or LlamaIndex. We have shipped production systems with both. Here is an honest comparison based on that experience — not a feature matrix copied from the docs. Quick context Both libraries have matured significantly since their early versions. LangChain went through a messy period of API churn around v0.1/v0.2...

My New Developer Spent 2 Hours on Our README. Docker Fixed It in 5 Minutes.

Last month, a new developer joined our team. I pointed them to the project README. It had 15 steps to set up the environment. By lunch, they were still stuck on step 4. Their Node version was 20. The project needed Node 16. They had a Windows machine. I was on a Mac. The "Standard Setup" was a myth. The Wrong Approach For months, I tried to solve this with documentation. I added more...

Why Sagas (and Why Not Distributed Transactions)

You have 5 microservices. An order comes in. You need to validate the product, charge the customer, and reserve inventory. If any of those steps fails, you need to undo the ones that already succeeded. The textbook answer is a distributed transaction with two-phase commit (2PC). Lock all resources across all services, do the work, then commit everything at once. The problem: 2PC doesn't scale. It...

Vertex AI Feature Store with Terraform: BigQuery Offline + Bigtable Online Serving 🗃️

Feature Store on GCP uses BigQuery as the offline store and Bigtable for low-latency online serving. Feature groups register your data, feature views sync it to the online store. Here's how to provision the full stack with Terraform. In the previous posts, we set up Workbench for development and deployed endpoints for inference. But the features feeding those models need a home. Training uses his...

Why Every Small Business Needs a CI/CD Pipeline in 2026

If you're still deploying your application by SSHing into a server and running commands manually, you're not alone — but you're losing money. Every manual deployment is a risk: a forgotten step, a typo in a command, or a missing environment variable can bring your site down. I've seen teams spend 2-3 hours on each deployment, doing the same repetitive steps every time. That's 2-3 hours of skilled...

yet another question on dynamically adding rows to table body

This executes without errors and gives correct values for cntr_a/b/c/d so all functions are executing in correct order, yet does not populate the table. That's the problem. Various tutorials indicate insertRow() and insertCell() by themselves are sufficient i.e. no tbody.appendChild(row) is needed. So what am I missing? var canned_list = [{"startTime":"2025-06-20T20:30","stopTime":"2025-06-20T2...

Solving the 100M-Row Problem: A Summary Table Pattern for High-Volume Push Notification Logs

How I redesigned a push notification logging system that had accumulated 100 million rows — without a single minute of downtime — using a summary table pattern, idempotent aggregation, and safe batch deletion. When your push notification service sends 500,000 messages per job and those logs never get cleaned up, you end up with 100 million rows in a single MSSQL table. Every statistics query be...
