AI in Long-Lived Systems
Every AI integration is a bet that you can monitor something you do not fully control.
Notes on Systems
Writing on systems, AI, data, and software.
Thoughtful notes for teams trying to reduce work, keep context intact, and build systems that stay understandable under pressure.
This is where Brimtech shares essays, field notes, and operating ideas.
Latest notes
Start anywhere. The throughline is operational clarity.
Tooling and Accidental Complexity
No one decides to make a system heavy. It happens one reasonable choice at a time.
Abstractions That Age Poorly
Good abstractions compress complexity. Bad abstractions relocate it.
Refactoring as a Signal
The code that needs refactoring most often is rarely the worst code. It is the code sitting on top of a structural assumption that no longer holds.
Defaults Nobody Revisits
Best practices are useful until they become borrowed conclusions that no longer match the system’s actual constraints.
The Carrying Cost of Flexibility
Speculative flexibility often looks responsible at first, then quietly raises the cost of understanding, testing, and changing the system.
Time As A Design Constraint
Systems age whether we plan for it or not, and the best design decisions are often the ones that remain legible long after their original context is gone.
When Code Is No Longer Scarce
As code generation gets cheaper, the real bottleneck shifts from production to coordination, comprehension, and judgment.
