Some minor things in the paper edition that says “3 2020” on the title page verso, not mentioned in the book’s errata online:
p. 186 But Erlang (and it’s progeny … should be: its
p. 205 chart O(n ln n) should be: O(n lg n)
p. 221 Ad Hoc Testing “run poke at our code manually”: I’m not sure exactly what is meant here. Maybe leave out “run”: poke at our code manually
p. 222 “Ignore a spew … makes it easier to ignore all the tests”: not sure what this means. “Ignore a spew”?
p. 226 “raise Exception”: needs to be indented two more spaces (significant in Python)
