The 3-Month Rule: My Technical Framework for Doing Things That Don’t Scale Variation 221

Embracing the 3-Month Rule: A Strategic Framework for Non-Scalable Solutions

In the tech world, we often hear the phrase from Paul Graham: “Do things that don’t scale.” While this concept is widely acknowledged, the practical implementation, particularly in the realm of coding, is rarely discussed.

After dedicating eight months to developing my AI podcast platform, I’ve formulated a straightforward yet effective approach: each non-scalable solution I employ is given a lifespan of three months. Within this timeframe, a strategy must either demonstrate its value and transition into a fully developed solution or be retired from use.

As engineers, we receive rigorous training to construct scalable solutions from the outset, focusing on design patterns, microservices, and robust architectures designed to support millions of users. Unfortunately, this mindset often aligns more with corporate development than with the dynamic environment of a startup. Here, pursuing scalability prematurely can lead to over-engineering and wasted resources—essentially procrastination for problems that may never arise.

By adopting the 3-month rule, I find myself compelled to produce straightforward, if imperfect, code that can quickly go live. This method allows me to gain valuable insights into what my users truly require.

Current Infrastructure Strategies: Why They’re Brilliant

1. Unified Virtual Machine Usage

All of my backend functions—including the database, web server, background jobs, and caching—run on a single $40/month virtual machine. While this may seem reckless due to the lack of redundancy and reliance on manual backups, it has been incredibly informative. Over the past two months, I’ve learned more about my resource requirements than any planning document could provide. The reality is that my “AI-heavy” platform only peaks at 4GB of RAM. Had I implemented a complex Kubernetes architecture, I would have been managing vainly empty containers. Each crash has yielded crucial insights about failure points that I never anticipated.

2. Hardcoded Configuration Values

I’ve opted for hardcoded constants rather than configuration files or environment variables. Modifying any settings involves a redeployment, but this approach brings its own advantages. I can easily search my entire codebase for configuration parameters with a simple grep command. This means all pricing changes are meticulously logged in git history, and updates are subject to my own code review processes. The time I save—15 minutes to redeploy versus an extensive 40 hours to build a configuration service—speaks for itself.

3. Production Use of SQLite
