Building SaarDB, Part 6: How SQL Queries Become Key-Value Operations

In Blog 5, we built a SQL parser. It can take this: INSERT INTO payments VALUES (500, payment_1, pending, 1) and turn it into a struct: InsertIntoTable{ TableName: "payments", ColumnValues: []string{"500", "payment_1", "pending", "1"}, } But this is still not enough for the storage engine. Our storage engine only knows how to store key-value pairs. It does not know what ...

How to Set Up Rate Limiting on Any Web App (Free, No Code Changes)

The Problem Your login page, search endpoint, or contact form is getting hammered. Rate limiting is the fix — but implementing it in application code means finding every endpoint, writing middleware, choosing a storage backend, and deploying changes. On a WAF, you set it once and it applies everywhere. Why WAF-Level Rate Limiting Is Better Approach Code-Level WAF-Level ...

Groq Returned Empty Content. The Bug Was Hiding in Reasoning Tokens.

This article was originally published on Jo4 Blog. We use Groq's gpt-oss-safeguard model to classify pages behind freshly created short links. Most pages take a few hundred tokens to score. Some don't. And the ones that don't were silently failing — for weeks — until we noticed the symptom: a small but consistent stream of links stuck in "preview pending" forever. Here's what we found. ...

Proving a proof-of-work solve happened, at a specific time, without trusting the server's logs

The problem: a solve is a fact that only lives in one server's memory If you gate a route with proof-of-work, every accepted solve is a real event. Someone burned real compute, at a real wall-clock moment, to get past the gate. That is exactly the property you wanted: the gate costs the caller something. But where does that fact live? In the verifier's memory, for as long as the proces...

How in 20 seconds, HPE takes you from siloed data to one connected platform with video storytelling | Explained by Advids

AI promises massive business benefits, but most data centers and IT teams simply aren't structurally ready for the revolution. HPE bridges this gap in seconds with their Juniper AI data center solution, delivering high-performing, scalable networks purpose-built for AI training and inference. Scalable AI requires an operations-first network Most teams assume that scaling AI inf...

Can you run a GNN without anyone seeing the data? Journal of our experiments on privacy-preserving GNN inference on microcontrollers

I have been keenly interested in how to make Graph Neural Networks (GNN) run securely on resource-constrained devices. The question driving this work is deceptively simple: can three microcontrollers jointly compute GNN inference on traffic data such that no single device ever sees the plaintext, not the input features, not the model weights, not the intermediate activations? This post is about th...

I Moved My Portfolio Off a Raspberry Pi to Cloudflare Workers

For about a year, my portfolio at rubarajan.dev was served by nginx on a Raspberry Pi sitting in my house, exposed to the internet through a Cloudflare Tunnel. Deploying meant running an scp script from my laptop. It worked. That's the thing — it genuinely worked, for a year. But the site is 500 KB of static HTML, CSS, and fonts. No backend. No build step. No database. There was nothing about it ...

Can you steal a robot's next move by watching its clock? Journal of our experiments on timing side channels in multi agent RL

I have been keenly interested in the intersection of multi-agent reinforcement learning (MARL) and hardware security. When you deploy a trained RL policy onto a microcontroller, the model runs inference to decide what action to take. But here's the thing: different actions can take different amounts of time to compute. If an adversary can measure that timing, can they figure out what the agent is ...

I turned a drawer of old Android phones into screen-off security cameras

Old Android phones pile up in a drawer. Each one still has a usable camera, Wi-Fi, and a battery — everything a basic security camera needs. So instead of buying a dedicated cam that routes video through someone else's cloud, I've been building an app that repurposes the phone you already own into a screen-off camera you can watch remotely. The idea The whole point is to keep an old ph...

Memory Management and Optimization in JavaScript

When building JavaScript applications—whether front-end or back-end—performance is more than just execution speed. Memory management plays a vital role in how smooth and responsive your applications feel. Poor handling of memory often results in sluggish user experiences, freezes, or even crashes. Understanding how JavaScript manages memory and applying optimization techniques can drastically impr...

I made my product database queryable by AI agents — a free API + MCP endpoint

AI assistants are quietly becoming the discovery layer. People don't Google "best power station for a camper van" as much anymore — they ask ChatGPT or Claude. The problem: for a niche like portable power stations, the model usually answers from stale, half-remembered specs and just makes numbers up. I maintain a structured database of 102 portable power stations (specs, $/Wh, cycle life, a trans...
