Embracing the 3-Month Rule: A Practical Approach to Building an AI Podcast Platform
In the startup world, the well-known adage from Paul Graham to “do things that don’t scale” often seems easier said than done, especially in the realm of coding. During my eight months of developing an AI podcast platform, I have adopted a straightforward methodology: each unscalable approach only lasts for three months. After that period, it must either demonstrate its worthiness for more robust development or be eliminated entirely.
As engineers, we frequently fall into the trap of prioritizing scalability from the outset, focusing on advanced design patterns, microservices, and distributed systems meant for large user bases. However, in a startup environment, striving for scalable solutions can often lead to costly delays, as we end up optimizing for issues that may never arise. My three-month rule pushes me to produce straightforward, albeit imperfect code that gets deployed and ultimately reveals what my users truly need.
Current Infrastructure Hacks: Insights from My Choices
1. Consolidated Resources on a Single VM
I run my entire infrastructure—including the database, web server, and background jobs—on a single $40-per-month virtual machine with zero redundancy and manual backups.
This might sound risky, but it has provided invaluable insights into my resource requirements. Instead of relying on hypothetical capacity-planning documents, I’ve gained concrete knowledge about my system—a mere 4GB of RAM supports my so-called “AI-heavy” platform. The extensive Kubernetes setup I had considered would have merely been managing idle containers. Plus, the crashes I’ve experienced have given me real feedback on what breaks—information I likely wouldn’t have accessed otherwise.
2. Embracing Hardcoded Configuration
Rather than utilizing configuration files or environment variables, I use hardcoded constants throughout my codebase, such as:
python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"
This approach allows me to quickly locate any configuration values across my files with a simple search. Changes are meticulously tracked in my git history, ensuring that each modification undergoes a review process, even if it’s just my own.
Building a full configuration service would have demanded significant engineering time, but with my current setup, changes have occurred sparingly. This method has saved me from expending hours on overhead while still allowing for quick adjustments.
