Embracing the 3-Month Rule: A Practical Framework for Non-Scalable Solutions
In the world of startups, the mantra “Do things that don’t scale,” popularized by Paul Graham, is widely acknowledged yet rarely dissected, especially in the realm of software development. After eight months of building my AI podcast platform, I’ve crafted a straightforward yet effective strategy: every unscalable approach receives a trial period of three months. During this time, it must either demonstrate its value and earn a permanent place in my codebase or be made obsolete.
A Common Misstep in Engineering
As software engineers, we often fall into the trap of constructing scalable solutions from the outset. Our training emphasizes the use of design patterns, microservices, and sophisticated architectures designed to accommodate millions of users. However, this mindset can stymie the agile, iterative progress crucial for a startup, where it’s easy to get sidetracked by hypothetical scalability rather than focusing on real user needs. By implementing a three-month rule, I’m encouraged to create straightforward, sometimes “messy” solutions that deliver real results and insights.
Current Infrastructure Hacks: Thinking Outside the Box
1. Consolidation onto One Virtual Machine
I’ve opted for a single $40/month virtual machine that hosts my database, web server, background tasks, and caching system. While this might sound like a recipe for disaster due to the lack of redundancy and manual backups, it has proven to be a brilliant move. By operating in this streamlined setup, I have gained invaluable insights into my actual resource usage within just two months. With peaks reaching a mere 4GB of RAM, it became clear that the complex Kubernetes architecture I nearly implemented would have ended up managing idle resources.
When downtime strikes—twice so far—I gain meaningful insights into the specific failure points, which are often unexpected.
2. Simplicity of Hardcoded Configurations
By embedding configuration values directly into my code, I’ve eliminated the need for cluttered configuration files and environment variables. While this may seem impractical, it offers a streamlined approach: every configuration change is easily searchable and tracked through version control. The overhead of developing a dedicated configuration management system would have taken significant time, while my method has sufficed with just three adjustments over three months, saving me countless engineering hours.
3. Utilizing SQLite for Production Use
Yes, I made the unconventional choice of using SQLite for a multi-user web application. With a compact
