I'm not sure how HN let's me post it.
I apologize for the link I posted.
You are somehow always able to find links that have been posted earlier. How do you do it? If you tell me how, I'll do it before I post a link so I don't duplicate.
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
It had been previously submitted over 1200 days ago(http://news.ycombinator.com/item?id=12964).
Anyway, thank you for telling me how I should search for articles. That's a great tip.
