AI Agent Security: Stop Model Exfiltration and API Key Leaks

Why AI Agents Expand the Security Perimeter AI agents do more than generate text. They call tools, query databases, retrieve documents, execute code, and communicate with external services. Every connection introduces a potential path for model exfiltration or credential leakage. Model exfiltration includes direct theft of model weights, systematic extraction of proprietary behavior, a...

I got tired of online JSON tools crashing on syntax errors and conversions, so I built a local-first repair engine

Every developer uses online JSON formatters daily to debug API responses, inspect log files, or check database dumps. But standard JSON formatters come with two recurring papercuts: Parser Fragility: Standard JSON.parse is unforgiving. A single trailing comma, missing quote, or Python-style True/False boolean completely crashes the formatter, forcing you to fix it manually character by charac...

LLD Data Structures in Design Context: The Heap Property — The Simple Rule That Makes Heaps Powerful

"A Heap doesn't stay useful because everything is sorted. It stays useful because every parent follows one simple rule." In the previous article, we learned that a Heap is built for continuous decision-making. Whether it's assigning the nearest driver, scheduling the next process, or selecting the most urgent support ticket, the system always needs one thing: The next best candidate B...

The Unbuffered Channels In Go Lesson I Think Has Finally Clicked for Me 🤷🏽‍♂️

While struggling to understand channels in go, I would try out many things in my sandbox repository. I encountered deadlock errors and stuff about go routes being asleep. I came to understand that the order of execution played a role and that with unbuffered channels you need a sender and a receiver ready at the same time (kind of). I wrote a short article on my blog site about the experience ...

Unpopular take: Using AI for documents: Content is more important that who wrote it

I wonder where the public opinion sways on this topic. My take has always been the most important information is what's in the document/paper/etc rather than if AI wrote it. However I have seen a lot of people say "This is written by AI, I won't read it". Normally I just ignore and keep going but this time I had a project update with a lot of good content which I used AI to help me tight...

LLD Data Structures in Design Context: Heap — A Data Structure Built for Continuous Decision Making

"A HashMap helps you find what you already know. A Heap helps you decide what should happen next." In the previous article, we discovered that not every software problem is about finding a specific object. Sometimes, the system already knows exactly what it's looking for. Find User ID = 1024 ↓ Return User Other times, the system doesn't know the answer in advance. Instead, it has t...

LLD Data Structures in Design Context: Why Some Problems Need the "Best" Result Instead of Any Result

"Finding something quickly and finding the best thing quickly are two completely different engineering problems." So far in this series, we've explored one of the most common behaviours in software systems: Fast lookup. Whenever a system already knows what it's looking for—a User ID, Product ID, Order ID or Session ID—a HashMap becomes an excellent choice. But not every software problem work...

My determinism test passed for months while the two builds played different games

I compiled the rules engine of a shipped Android game to the browser. Same Java, two compilers. Then I checked whether the two agreed. They did not — and the test I already had for exactly this had been green the whole time. The same command twice: green against the current engine, then against the committed recording of the broken build. Play it as a terminal session if you want to select the...

What Is Model Context Protocol (MCP)?

The Model Context Protocol is an open standard, introduced by Anthropic in November 2024, for connecting AI models to the tools, data, and systems they need to be useful. The easiest way to understand it is through the metaphor most people in the space now reach for: MCP is "USB-C for AI." Before USB-C, plugging a device into a computer meant hunting for the right proprietary cable. MCP solves the...
