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...

I Keep Forgetting to Delete My AWS Test Resources, So I'm Building a Tool to Yell at Me Instead

We've all done it. You spin up an RDS instance to test something on a Friday afternoon. You attach an EBS volume to a t3.micro that you kill three days later — but the volume just... stays. You allocate a static IP for a load test, and the load test ends, but the IP doesn't know that. None of this shows up as an error. Nothing crashes. There's no red banner in the console screaming at you. It ju...

Same DeepSeek V4 Flash, Different Agent: Why the Runtime Changes the Result

Same DeepSeek V4 Flash. Different runtime. Very different long-task outcomes. My local sample is bounded: Codex + Flash completed a long, cross-file, repeatedly verified deck task; Claude Code + Flash launched multiple reviews, but their quality was not independently verified. This supports different pairings, not a universal ranking. The useful unit is not a model ID. It is a complete runtime: ...

The AI/ML Engineer Roadmap Nobody Actually Finishes (But You Should Try)

Okay real talk — if you've googled "how to become an AI/ML engineer" you've drowned in roadmap images that are just... a wall of logos. TensorFlow logo, AWS logo, Docker logo, arrows everywhere, zero actual explanation of what to do with any of it. So here's an actual phase-by-phase breakdown, with checkpoints, so you know when to move on instead of doom-scrolling more "10 skills you need" listic...

Function Calling With a Local LLM to Drive Foundry: Fuzz, Read, Repeat

The first time I let a local model drive Foundry unsupervised, it spent eleven turns trying to fix a fuzz test by renaming the test function. Not changing the logic. Renaming it. testFuzz_withdraw, then test_fuzz_withdraw, then testWithdrawFuzz, each time running the suite and reading the same compiler error with fresh optimism. That experiment still turned into one of the more useful tools in my...
