Following renewed interest in duploids arising from the exponential comonad of linear logic (the construction describing polarised intuitionistic translations into linear logic), I summarise here various remarks: • about a decomposition of Girard's "boring" translation as the expression of call-by-value in call-by-name, dual to how thunks are used to express call-by-name in call-by-value • about the coincidence between linear CPS translations and Girard's translations of intuitionistic logic into linear logic, • about a completeness property of historical models of linear logic in the above context • about a rational reconstruction of these translations with the Linear Call-by-Push-Value.
