Your First Hundred Customers Are Supposed to Be Wrong

One developer, one library, and a wake-up call that exposed how the tech industry builds billion-dollar products on infrastructure no one is paid to maintain.

Market leaders spend enormous resources winning dominance. Their closest rivals collect the profits. Here's the structural reason why.

Optimizing your productivity system feels like work. But the best system isn't the most elegant one — it's whichever one you'll actually open tomorrow.

Before you ship anything, customers are buying something. Most founders don't know what it is, which is why so many early deals fall apart.

Being first sounds like an advantage. The history of tech says otherwise. Here's what actually separates pioneers from the companies that bury them.

Adding more detail to your AI prompts feels like it should help. Sometimes it does the opposite. Here's why, and what to do instead.

Some bugs disappear the moment you look for them. Understanding why is more useful than any debugging trick.

Speed rarely comes from faster hardware or smarter algorithms. It comes from eliminating work the program never needed to do in the first place.

Jeff Dean's famous latency cheat sheet shaped a generation of architecture decisions. The hardware it described no longer exists.

Forgotten code written by engineers who retired decades ago is quietly keeping hospitals, power grids, and financial systems alive. That should worry everyone.

Picking the mid-range cloud tier feels prudent. In practice, it combines the worst cost properties of both ends of the pricing ladder.

Most remote teams interpret async-first as 'fewer meetings.' That's a surface-level reading that misses the harder, more important half of the idea.

Every ping on your phone was designed by a team optimizing for re-engagement metrics. Understanding the system helps you fight back.

Pricing isn't just a revenue decision. It's a signal that sets buyer expectations permanently. Basecamp learned this the hard way.

Some early revenue isn't just low-quality, it's actively corrosive. Here's how to recognize the customers who will hollow out your company before you ever find product-market fit.

LLMs don't read your code the way you do. Understanding the gap changes how you use them effectively.

The hottest job title in AI is a repackaging of something engineers have done for decades. That doesn't make it useless — it makes it misunderstood.

Null means unknown. Zero means zero. Confusing them is one of the most common and expensive bugs in production databases.
