All articles and modifications to articles go to moderation, where the community (or a trusted subset ot if at least) read and decide if it is suitable for publication, or if it needs changes first. This doesn't normally take too long, but all moderators are busy volunteers, and it requires the agreement of five such to get it approved.
Your original Tip is in the mod queue, and short be released soon, you new one is posted as an article, and may need changing to a tip to get through (like your first one, it's kinda short and "lightweight" for a full article).
Please, look at some of the existing articles here to get an idea of the standard we expect.

And here's a tip which is a lot more "code focussed":

We moderators aren't here to make your life difficult, or to be nasty - quite the reverse, we protect the site from not-ready articles, and authors from the derision and downvotes that poorer articles can receive. And to be a moderator, you have to write articles, so we know what it feels like when you slave away on something and Joe Moron from Stupidity High School, Kansas finds out it's not what he needs to hand in as his homework ... :laugh:
