I&#x27;m speaking as a programmer and a sysadmin.<p>Lab notebook as it is may not be
that useful, because it gives mostly constrained note fields set. But if we
extend it to a notebook with a sheets of paper that are blank, barring
possibly a distinguished header field, well, I use one every day.<p>Sysadmin could use several types of worksheets, with fields and checkboxes
designed to aid in particular tasks, but those would be exactly that: sheets,
not whole notebooks.
