Notes
Technical notes
Technical writing around actual engineering work: Windows internals, power measurement, diagnostics and the decisions behind the tools.
No articles published yet.
Writing starts when there is a real investigation to write up. The topics below are the ones currently planned.
Planned topics
Windows power telemetry
What the platform exposes about power draw, and where those numbers come from.
ETW
Using Event Tracing for Windows to observe system behaviour without distorting it.
Battery and energy analysis
Reading and interpreting battery and energy reports as evidence rather than a summary score.
Measurement methodology
How to design measurements that can be repeated and compared.
Power attribution
Moving from "the system used more power" to "this is what caused it".
Optimisation experiments
Testing whether a tweak actually changes anything, and reporting when it does not.
Architecture decisions
Why the tools are built the way they are, including the trade-offs.
Debugging and postmortems
Investigations into real failures and what they revealed.
