The UniFi controller update reset my DNS filtering profile to “default” without a word. Twenty minutes of very confident debugging later: it was the router, and the router had told nobody.
Notes
Notes feed (RSS)Short ones. A paragraph, a gotcha, a thing I want to be able to find again.
These are the most frequent thing here and the least worked-on, by design. They also turn up in the Stream alongside everything else; this page is for when you only want the short stuff.

Spent twenty minutes convinced a switch port was dead. It was the cable, which I had personally labelled “good” in 2021. Relabelled. Trust nothing you wrote on tape five years ago.

Airport wi-fi that works for everything except one app is almost always a captive portal that has expired quietly in the background. Load any plain HTTP page and it will admit it.

A multimeter with a continuity beeper is worth three without one. You can keep your eyes on the probes instead of the display, and that is the entire job.

Every time I have said “it can’t be the power supply” out loud, it has been the power supply. I have started saying it deliberately now, as a diagnostic.

Writing the runbook while the thing is still broken produces a much better runbook than writing it afterwards, when you have already forgotten which step was the confusing one.

I enjoyed Michael Lopp’s article An Introduction to You, specifically this part:
We are in an incredible hurry building important things and have no time for nuance. We’re impatient. We’re busy. We want everything to move faster, so we make huge, comforting assumptions and slap easy to understand labels on complex concepts.
Though I’ve been thinking little about the idea of oversimplifying and therefore over or under estimating the contribution of a new employee. Rather the quoted section made me think about how much is often missed in the “incredible hurry” when building products and the systems and processes to support a business.
It would have resonated more with me if he had written the exact same article but if it were not about an employee, but a new technology being integrated into the same busy-worshiping company culture.

A great example of someone paying close attention to reality while experimenting with changing their way of working to achieve success they didn’t believe possible.
Definitely worth a read.
