Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

Polymorphic Associations reversed

It's pretty easy to do polymorphic associations in Rails: A Picture can belong to either a BlogPost or an Article. But what if you need the relationship the other way around? A Picture, a Text and a Video can belong to an Article, and that article can find all media by calling @article.media

This example shows how to create an ArticleElement join model that handles the polymorphic relationship. To add fields that are common to all polymorphic models, add fields to the join model.

	function copyToClipboard(text) {
	if (window.clipboardData && window.clipboardData.setData) {
	/IE specific code path to prevent textarea being shown while dialog is visible./
	return clipboardData.setData("Text", text);

	} else if (document.queryCommandSupported && document.queryCommandSupported("copy")) {
	var textarea = document.createElement("textarea");
	textarea.textContent = text;
