Weird. Previously submitted here: http://news.ycombinator.com/item?id=1801632

Not weird, timing is sometimes everything. Sometimes a perfectly good essay is submitted after everyone goes to bed, or they are too busy to read a long item so they don't vote one way or the other. If the post fails to get that crucial push of votes in the first hour, it dies.

The exact same thing resubmitted first thing on a Monday morning gets an entirely different reception. I guess that's just how things go, I hope people don't take this resubmission as spammy behaviour or as trying to steal karma from you :-)

Usually when you submit something that's already been submitted semi-recently, it'll send you to that submission and up vote it automatically. It matches the URL

I'm not sure if theres a timeframe for this - I've seen it on something as long as a few months.

That is true if the urls are the same but in the previously submitted one #readme is appended and this one lacks that.

I believe that dups with the same url are caught as long as they are in memory on the server.

The URL comparator appears to be a simple (case-sensitive!) string comparison. There are many ways around the dupe filter.

Oh, sure!

No, actually I was just surprised the URL dupe-matcher didn't catch it. I see now they have a minor difference, though it indicates how easy it would be for someone to bluff the dupe finder if they wanted to.

Mainly, though, I'm glad there's discussion on your post.
