A model drafting documentation from a repository describes what exists far better than what does not, because the code is a positive artifact: routes, flags, and types are visible, while "this endpoint rejects batched writes" exists only in someone's head. That asymmetry is the practical failure you have to design around, and it does not go away with a bigger model or a longer prompt. The contr...
Python raises UnboundLocalError: cannot access local variable 'x' where it is not associated with a value when a function reads a name that Python has decided is local to that function, but the line that gives it a value has not run yet. Any assignment to a name anywhere inside a function (including +=, for, import, del an...
undefined means a value was never assigned (missing property, missing argument, bare return). null is an intentional empty value you assign yourself. Prefer === when you care which one you have, use == null when either should count as empty, and reach for ?? / optional chaining when you want defaults without t...
A gate that averages three weak signals into one score will admit patches it should have held. The fix is not a better score. It is a fixed precedence order between channels that answer different questions, plus a resolver whose only job is to say which channel wins.
Below is a design for that resolver. It assumes you already collect three kinds of evidence for agent-authored patches: p...
I've heard this question come up many times over the years, and I've been involved in quite a few discussions about it myself: how do you collect metrics from an application running in a container if the application doesn't expose an HTTP /metrics endpoint?
Maybe it was never designed to do that. Or maybe adding an HTTP server just for monito...
I've been working on an open-source project called Switch USB Inspector, and I'm happy to share its first release: v0.1!
The project started with a simple idea: create a lightweight tool capable of inspecting connected USB devices and displaying useful information about them, inc...
