What an LLM Actually Does With Its Context Window

First-time founders are naive enough to be fearless. The second time, you know exactly what can go wrong. That knowledge is a liability.

AI coding tools are genuinely useful. They're also structurally blind to whether the code they produce actually does what you need. Here's what that means for your workflow.

A single click triggers dozens of coordinated operations across global infrastructure. Most of them are invisible. None of them are simple.

The client relationship that nearly tanks your startup often signals you've found someone who actually cares. That's rarer than it sounds.

A look at how one product team discovered their task system was rewarding capture over completion, and what they changed to fix it.

Early Dropbox faced intense pressure to go enterprise. Understanding why they resisted, and what happened when they briefly didn't, is a masterclass in knowing which customer to believe.

Better reasoning doesn't fix hallucination. It makes the model better at sounding right while being wrong.

Most distributed systems bugs aren't logic errors. They're retry errors. Idempotency is the property that makes retrying safe, and almost nobody designs for it deliberately.

Being first in tech often means paying the education costs so a better-positioned rival can collect the tuition. The numbers back this up.

The design of most task systems rewards adding work, not completing it. Here's why that happens and how to fix it.

Every famous pivot story has a villain. It's usually the first customer the founders thought they needed.

AI models update without announcements, and your carefully tuned prompts may stop working the moment the model underneath them changes.

A design team's year-long experiment with every major productivity tool reveals what actually makes systems stick — and it's not the software.

AMD spent years as Intel's shadow. That positioning, not a product breakthrough, is what eventually made it one of the most profitable chip companies in the world.

The marginal cost of software is genuinely zero. The price never is. Understanding the gap between those two facts explains most of how the tech industry works.

Underpricing feels safe. It's one of the most reliable ways to kill a company before it ever gets the chance to figure out what it's actually worth.

Giving an LLM access to 200,000 tokens doesn't mean it actually attends to all of them. Here's why context window size and context utilization are different problems.

Before you reach for Postgres or Redis, consider what your filesystem already gives you for free: indexing, transactions, access control, and surprisingly good performance.
