Binary codes capable of correcting deletions, insertions, and reversals (1965)

I love that people keep finding these old papers to post. For me the most frustrating aspect of "technology" is the constant reinvention of the already (mathematically) perfected wheel, poorly. We should look to the past for wisdom before reinventing what someone wiser than us has already perfected.<p>Keep posting this stuff.

Lately a lot of PDFs --- even if not from scribd --- get the [scribd] postfix? Is it because the original authors posted a scribd link and it got changed?<p>I'd just ban scribd links. I think HN readers can be expected to google the title of whatever they found on scribd and post the original PDF or (hopefully!) webpage.
