A Rant About Kilograms On Mars

The CACM have published a reasonably interesting article by Gerard J. Holzmann about verification of the software on the Curiosity Rover: Mars Code.

Near the beginning, though, it says:

"It's" & "its"

Dear Web,

The words it's and its are distinct and not interchangeable. Abuse rarely produces real ambiguity though it often results in the need to backtrack and reparse a sentence thereby slowing down reading but it does have the benefit of flagging the writer as likely to be careless: a powerful but not 100% accurate initial filter to apply to Internet writing.
