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

Embracing the 3-Month Rule: A Pragmatic Approach to Unscalable Solutions in Tech

In the world of technology, renowned entrepreneur Paul Graham’s mantra resonates deeply: “Do things that don’t scale.” However, while the concept is well-understood, the methods to effectively implement it in the coding realm can be elusive. After spending the past eight months developing my AI podcast platform, I’ve created a straightforward framework: every unscalable hack is given a lifespan of three months. At the end of that period, it must either demonstrate its worth and be fully developed or be discarded altogether.

As software engineers, we are often conditioned to focus on scalable solutions right from the onset. We get enamored with concepts like design patterns, microservices, and distributed systems—architectures that promise to handle vast numbers of users efficiently. Yet, this is typically a mindset suited for large enterprises.

In the startup environment, however, focusing on scalability often turns into an exercise in delayed action and resource wastage. You’ll find yourself optimizing for hypothetical users and addressing issues that may never arise. My three-month rule compels me to embrace simpler, more straightforward code—what some might consider “bad”—that can be deployed quickly and provides valuable insights about user behavior.

Key Infrastructure Strategies That Are Surprisingly Savvy

1. Running Everything on a Single Virtual Machine

Currently, my entire stack—database, web server, background processes, and Redis—is hosted on a single $40 monthly virtual machine. This setup lacks redundancy, with backups executed manually on my local machine.

Why is this a wise choice rather than a flaw? After just two months, I’ve gained a far greater understanding of my actual resource requirements than any capacity planning document could offer. It turns out that my AI-focused platform only needs 4GB of RAM at peak usage. The intricate Kubernetes infrastructure I considered would have just led to managing empty containers.

When the server crashes (which it has a couple of times), I receive genuine insights regarding failures—spoiler alert: they are often not the issues I initially anticipated.

2. Utilizing Hardcoded Configurations

python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"

Gone are configuration files and environment variables; instead, I have constants embedded throughout the codebase. Changes necessitate a redeployment
