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

In the world of startups, the wisdom of Paul Graham’s statement “Do things that don’t scale” often rings true yet remains largely underexplored when it comes to practical implementation in software development. After months of directly engaging with this philosophy while building an AI podcast platform, I have formulated a straightforward yet effective framework: every unscalable hack or solution is given a lifespan of three months. At the end of this period, the approach either validates itself and transitions into a full-fledged solution or it gets phased out.

The startup Mindset: Rethinking Scalability

Traditionally, as engineers, we are trained to create scalable solutions from the very start. This includes employing sophisticated design patterns, distributed systems, and cloud architectures capable of handling millions of users. However, this rationale often aligns more with the needs of larger organizations rather than the nimble, iterative nature demanded by startups. Opting for scalability at such an early stage can lead to unnecessary complexities, ultimately causing more delays than benefits.

My three-month framework compels me to prioritize swift, pragmatic coding practices that yield quick insights into user needs and operational realities.

Streamlining My Development Process: Current Hacks Explained

Here’s a glimpse into my current infrastructure strategies, which may seem unconventional but have proven to be effective learning tools:

1. All-in-One Virtual Machine

I’m currently operating everything on a single $40/month virtual machine, hosting the database, web server, background jobs, and caching. This setup might lack redundancy and relies on manual backups, but it has significantly accelerated my understanding of actual needs. Within just two months, I discovered that my so-called “AI-heavy” platform only peaks at 4GB of RAM. The intricate Kubernetes structure I once considered would have merely managed idle containers instead of driving value.

Whenever the system crashes (which has happened a couple of times), I gain invaluable insights about failure points, often revealing surprises.

2. Hardcoded Configuration Values

My codebase is filled with hardcoded constants for crucial parameters:

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

While this approach bypasses configuration files and environmental variables, it affords me remarkable efficiency. I can quickly search for any configuration and track changes
