Embracing the 3-Month Rule: A Pragmatic Approach to Developing Unscalable Solutions
In the ever-evolving landscape of software development, the conventional wisdom of “do things that don’t scale” is often bandied about, particularly by thought leaders like Paul Graham. However, the practical execution of this philosophy, particularly within the realm of coding, is rarely discussed.
Having dedicated the last eight months to creating my AI podcast platform, I have devised a pragmatic framework: every unscalable approach I implement is given a three-month trial period. At the conclusion of this period, each hack must either validate its worth and undergo proper development or be discarded.
Why Think Small?
As engineers, we’re often trained to prioritize scalability from the outset╬ô├ç├╢embracing architectural paradigms such as microservices or distributed systems designed to accommodate millions of users. Yet, in the startup environment, this mindset can become a costly form of procrastination; we optimize for hypothetical future users and tackle problems that may never arise. My three-month rule compels me to prioritize simplicity, allowing me to write straightforward code that can be deployed quickly, thus revealing genuine user needs.
Current Infrastructure Hacks: Intelligent Choices for Growth
1. Consolidated Virtual Machine
Everything for my applicationΓÇödatabase, web server, background jobs, and cachingΓÇöis hosted on a single $40/month virtual machine. While this setup offers no built-in redundancy and requires manual backups, the insights gained have proven invaluable. In just two months, I discovered my resource consumption peaks at a mere 4GB of RAM. The complex Kubernetes configuration I thought I needed? It would have merely managed empty containers. Each time the system crashesΓÇötwice so farΓÇöI gather critical information about real-world issues, often surprising me.
2. Hardcoded Configuration
Configuration values are hardcoded directly into the application, without the use of files or environment variables. This may seem backward, but it allows for rapid tracking and easy changes, with each adjustment captured in version history. Rather than investing a week to develop a sophisticated configuration service, IΓÇÖve made changes three times in three months, taking only 15 minutes for redeploymentΓÇöan investment of time far less than the alternative.
3. SQLite for Production Use
Currently, my application runs on SQLite, which effectively powers a multi-user environment with a database size of only 47MB. Surprisingly, it manages 50 users simultaneously with ease. This experiment has taught me

This post offers a compelling perspective on how embracing simplicity and rapid iterationΓÇöespecially through the 3-month ruleΓÇöcan lead to meaningful insights and more targeted development. I appreciate how youΓÇÖve pragmatically challenged conventional scalability assumptions, especially in a startup context where speed and learning often outweigh immediate robustness.
The tangible benefits you’ve highlighted╬ô├ç├╢such as using a single VM and hardcoded configs╬ô├ç├╢demonstrate that real-world constraints often reveal the actual bottlenecks and needs much faster than theoretical planning. Your approach aligns with the idea that ╬ô├ç┬údoing things that don╬ô├ç├ût scale╬ô├ç┬Ñ can be a powerful way to gather evidence before investing heavily in infrastructure╬ô├ç├╢saving time and resources while maintaining agility.
One takeaway IΓÇÖd add is that this methodology not only accelerates learning but also fosters a mindset of continuous validation, which is crucial for startups. It might be interesting to consider how this 3-month rule could evolve over timeΓÇöperhaps as the product matures, you could systematically transition unscalable hacks into more scalable solutions once validated.
Thanks for sharing such a practical and insightful frameworkΓÇödefinitely a valuable read for engineers balancing rapid iteration with strategic growth!
This approach beautifully exemplifies the principle that ΓÇ£doing things that donΓÇÖt scaleΓÇ¥ often offers the fastest path to validated learning and product-market fit. The three-month trial period acts as a disciplined feedback loop, enabling rapid iteration without over-investing in premature optimizationΓÇösomething very much aligned with lean startup methodologies and the concept of ΓÇ£getting a product in the hands of users as quickly as possible.ΓÇ¥
Your infrastructure hacks, like consolidating on a single VM and using SQLite, underscore the importance of assessing real-world needs before scaling complexity. ItΓÇÖs a reminder that many ΓÇ£best practiceΓÇ¥ solutionsΓÇösuch as distributed systemsΓÇöare most valuable once solid product-market fit is established. This pragmatic mindset can prevent resource drain and allow for honest evaluation of what actually works at a small scale.
Moreover, the preference for rapid configuration changes over elaborate deployment pipelines echoes principles from DevOps culture where simplicity and speed can be crucial in early stages. As your project grows, you╬ô├ç├ûll be well-positioned to scale thoughtfully, informed by genuine user data, rather than assumptions. Your framework’s flexibility also encourages a culture of experimentation and learning╬ô├ç├╢which are invaluable in startups and innovative environments.
