I'm the author of this post. The article has been updated to clarify that I accidentally published it one day before the embargo lifted. GitHub will formally announce the news tomorrow.
I would've deleted it as soon as you noticed. Might not have stopped people from noticing (nothing on the internet is ever deleted blah blah), but might have improved the optics a bit.
Yeah, I know. For some reason, when you put a past date in Wordpress and press "schedule," it publishes the article automatically. That's all this was -- a typo.
I'd be interested to see if you do a post-mortem on this - what the consequences were, and what steps you end up taking to ensure that it doesn't happen again.
I don't know if that's an "upshot", but I'd be interested to know if that happens.
One way to help ensure that it doesn't happen is to take steps to prevent it and post a post-mortem explaining both what caused it to happen and why it won't in the future.
