📚 node [[stpa handbook]]
- a [[book]].
[[Chapter 2]]
Good overall summary in the first page:
I wonder what the formalism is in this diagram. It is not an STPA diagram in the "main" sense as it doesn't model control loops explicitly, but is it part of the STPA framework?
First step: defining the purpose of the analysis.
[[Losses]]:
Definition of [[system]]:
[[hazards]] + [[environmental conditions]] = [[losses]]
The heart of STPA: the control loop.
Refining control structures:
On [[control]] proper:
tips to prevent common mistakes in a control structure:
Step three:

extend client:
- read from multiple API-sources
- read tags from API (not just from cache)
- integrate with [[web-clipper]]
- integrate with foam's wikilinks
- retrofit discussion threads to follow [[kialo]]

[[pull]] [[hypotheses]]
- "A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it."
- "A working hypothesis is a provisionally accepted hypothesis proposed for further research, in a process beginning with an educated guess or thought."
-
Hypothesis: what you see with your eyes closed, the lights you can see in the dark -- that is not random noise, it is computation.
- The visual cortex may be used to compute arbitrary programs given the passage of time: an image can encode a spectrogram, for example, and pattern recognition applied to shapes in the spectrogram may yield at least some useful sound information (given the "right" neural networks)
- Arbitrary programs could be stored and replayed in the visual cortex by e.g. evolving cellular automata or a neural network that can simulate them, which would seem to yield universal computation as per Wolfram et al
- Hypothesis: there is much in the nature of [[light]] we still do not know.
