The newest submission (before this one) was from over a year ago. I think you're okay–HN lets links be resubmitted after n days, I do believe.

I think it's fine to have resubmissions from time to time, though I can't say I personally like seeing the same links, there are new users to HN, and good articles resurfacing are an okay thing.

That being said, I'm not sure this is something that necessarily appeals to the kind of people who frequent this site, but I don't particularly care.

That being said, to answer your questions: http://searchyc.com/submissions/like+a+computer+scientist
