I'm starting to find that there are two good language-related indicators for how tired / distracted / overworked I am:
* How often I get bizarre misreadings or misparsings. For example, the other day I misread
«Premature optimization is the root of all evil in programming. --C.A.R. Hoare»
«Premature ejaculation is...». Which may be true, but still.
And today I saw "cost of living calculator" and parsed it as a "[cost of [living calculator]]" instead of "[[cost of living] calculator]". So I thought it was the value of a calculator made of living material. Spooky.
* How often really random and bizarre typoes creep into what I'm typing. Like if I mean "marshalling objects is a problem if the attributes are somehow ordered" but instead I type "marshalling objects is a released if the attributes are somehow ordered".
