Not a production outage.
Not deleting a database.
Not deploying on Friday.
The most expensive mistake I keep making is solving the same problem twice.
A few years ago, whenever I discovered something useful, I'd tell myself:
"I'll remember this."
A clever regex.
A SQL query.
A terminal command.
A React pattern.
A deployment fix.
Three weeks later, I'd be searching Stack Overflow for the exact same thing.
The problem wasn't forgetting.
The problem was not having a system.
That's why I started saving everything I learn as snippets.
Not just code, but explanations, commands, debugging notes, and useful references.
The result?
Less time searching
Less context switching
Fewer repeated mistakes
Faster onboarding to old projects
As developers, we spend a lot of time learning.
But learning only becomes valuable when we can retrieve it later.
Your future self is one of the most important users of your code.
Make it easy for them.
How do you currently store and organize your snippets and developer notes?
