PageRank is an algorithm. (Although it does piss me off that it's patented)

- tptacek 18y agoOk I'm guessing that there's more than a little bit of code that actually runs that algorithm.
- william42 18y agoHonestly, probably just a little bit. It's not that complex of an algorithm. The really complex stuff is MapReduce.
- tptacek 18y agoCan we just agree that there is quite a bit of Google code that is unlikely to ever be open-sourced? =)
- wallflower 18y agoReddit's open source code excludes the crown jewels of anti-cheating/spam protection. It's their IP.
- echair 18y agoSeems more likely that it's just that they don't want spammers and cheaters to know what their defenses are.
- wheels 18y agoWhoever voted that down has never looked at PageRank seriously. You can implement it in a few hundred lines of code using Page's paper from when he was at Stanford.
- s3graham 18y agoPageRank-Stanford-version might not be much code, but as I understand it, that's almost irrelevant to current search results which are much more complex.
- wheels 18y agoCertainly. I suppose it depends on whether you see PageRank as a specific algorithm (as I think most people reading papers on search algorithms do) or "the thing that powers Google's search results". My point was that the original comment wasn't just stupid.
