If Jon picked the right questions (and it definitely looks like he did), then you're asking about a question that received one stray downvote. Based on the title, I expected that the questions had been closed as
Subjective/Argumentative, but that's not the case here.
I doubt that the downvote on the first question had anything to do with the question being subjective - if that were the case, it would likely have been closed. It also wasn't downvoted to oblivion, it was only downvoted once; all that means is that one person saw your question and didn't like it.
My best guess as to why is that you seem to be asking a very basic question (how to write a loop), and whoever downvoted was having a bad day and decided that it was a "stupid" question, or perhaps a homework question. But I don't know that for sure - the fact of the matter is, people aren't obligated to explain their downvotes and one downvote (as opposed to a torrent of downvotes) doesn't really mean all that much.
As a rule, people will be nicer to you if you:
- Tag such questions with
beginner (full disclosure, so people don't assume it's homework etc.);
- Use more precise titles, such as How do I create a continuous animation for an analog clock?
They really weren't bad questions, IMO, it's just that they were awkwardly worded and a little RTFM-ish.
By the way, neither of those questions have anything to do with design patterns.
