ABOUT THIS NOTEBOOK
Make the next question better.
Signal Notes is a small collection of original engineering notes about networking, measurement and dependable operation. It favours clear boundaries, recorded failures and changes that can be reversed.
These articles are introductory notes, not product specifications or guarantees. Real systems deserve measurements made in their own environment.
