I'd upvote for the first part of the second sentence, but downvote for the second part of the second sentence. Typographically speaking English language text should have a wide space following a sentence-ending period [that isn't also a paragraph-ending period]. However, because wide spaces are not easy to type on normal keyboard layouts, the simplest thing to do is to type two spaces after sentence-ending periods and let the word processor change those to wide spaces when using a proportional font. When using a fixed-width font, however, it should always be two spaces after a sentence-ending period for two reasons: to disambiguate non-sentence-ending periods, and to make it easier to read. Coders write a lot of text in fixed-width fonts, so we should write two spaces after sentence-ending periods in, e.g., code comment blocks.
