Embracing the Unscalable: A Three-Month Approach to Learning in Development

In the world of startups, the mantra “do things that don’t scale,” made popular by Paul Graham, is essential advice. However, the challenge lies not in understanding this philosophy but in applying it effectively, particularly in the realm of software development. After eight months of diligently building my AI podcast platform, I’ve discovered a straightforward and impactful approach: the three-month rule for implementing unscalable solutions.

The Essence of the Three-Month Rule

As developers, we are often conditioned to focus on scalable solutions from the outset—design patterns, microservices, and distributed systems are staples of our training. While these concepts are undoubtedly valuable in larger organizations, they can lead to unnecessary complexity in a startup environment. The reality is that optimizing for future users who may never come can become an expensive form of procrastination.

My three-month rule revolves around the principle that any unscalable solution I deploy will have a lifespan of just three months. During this period, it must either demonstrate its value and evolve into a robust solution or be phased out entirely. This approach encourages me to write straightforward, albeit imperfect, code that provides insights into what users genuinely need.

Current Infrastructure Hacks and Their Value

Let me share some unorthodox practices I’ve adopted, each with a rationale that reveals their underlying wisdom.

1. Unified Virtual Machine Setup

All my services—database, web server, background jobs, and caching—run on a single $40/month virtual machine. This setup, devoid of redundancy and relying on manual backups, has provided invaluable insights. Within just two months, I learned about my resource requirements far more effectively than any capacity planning document could convey. It turned out that my “AI-heavy” platform only peaks at 4GB of RAM. Had I implemented a complex Kubernetes architecture, I would have been managing idle containers rather than focusing on real issues.

2. Simplistic Hardcoded Configuration

My configurations are hardcoded directly into the codebase:

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

While it may feel old-fashioned, this method allows for quick searches and easy tracking of changes through version control. The time saved—15 minutes for a redeployment versus 40 hours building a
