Export a Conda environment with --from-history, but also append
Pip-installed dependencies
Exports only manually-installed dependencies, excluding build versions, but
including Pip-installed dependencies.
Lots of issues requesting this functionality in the Conda issue tracker, no
sign of progress (as of March 2020).

NHST draft writeup

Null Hypothesis Significance Testing (NHST) is a procedure in which we try to learn something about the data by forming an hypothesis and then ruling out (or "rejecting) that hypothesis. Conceptually, NHST is similar to "deductive reasoning" in philosophy, or "differential diagnosis" in medicine: we can arrive on a single unambiguous conclusion only by ruling out all other possibilities. Therefore we can "prove" that the alternative hypothesis is true by ruling out the only other possibility, the null hypothesis.

In order to perform NHST, have to specify a null hypothesis, typically denoted H0, and an alternative hypothesis, typically denoted HA. H0 and HA must be mutually exclusive for NHST to make sense: if H0 is true then HA must be false, and if HA is true then H0 must be false.

NHST has two possible outcomes: we reject the null hypothesis in favor of the alternative hypothesis, or we fail to reject the null hypothesis. Failing to reject the null hypothesis does not mean that we reject

My attempt to understand Sans I/O style.

My attempt to understand Sans IO

The basic machinery is:

  1. An Event type
  2. A Client that receives "inbound events" (responses from previous i/o) and emits "outbound events"; one core implementation
  3. An IOClient that performs i/o based on outbound events and forms inbound events from i/o results; one implementation per i/o framework

Hypothetical implementations
