Article is unsupported by any reliable sources. The article topic is not notable enough for reliable sources right now. It does not seem that this topic should be in the wikipedia at present- prime-based hash functions are two a penny. Moreover, this article links only to sources controlled by User:Landon_Curt_Noll and is largely written by him. Phil Spectre (talk) 23:21, 28 September 2009 (UTC)
- I don't support deletion of this article. The article has 24 different editors (not counting bots) so I don't think it is fair to say that it "is largely written by [Landon_Curt_Noll]", indeed the article was not even originally created by Landon_Curt_Noll. Good non-cryptographic hash functions are not "two a penny", they are hard to design to get good results. Most hash function designers concentrate upon cryptographically strong hashes that are a lot slower. So there is definitely a place for the non-cryptographic alternatives that are faster. The FNV happens to fulfil a requirement in non-secure situations. The fasm project is well known and uses FNV for internal table lookups. From what I have seen the FNV hash has been around for some time now and seems to be quite well respected. HumphreyW (talk) 01:02, 29 September 2009 (UTC)
- The criteria for an article are WP:RS and WP:N, not whether you think it's a good hash. Notability is not earned by association: there is a precedent that being used by a notable project doesn't make the hash notable. And I looked at fasm but it doesn't even mention FNV. As for reliability, all of the sources are just Noll. Phil Spectre (talk) 01:12, 29 September 2009 (UTC)
- Sorry, I didn't realise the fasm article does not mention it. But the authors site has it mentioned here. HumphreyW (talk) 01:57, 29 September 2009 (UTC)
- The way I see it, the fact that fasm didn't, and still doesn't, mention FNV means that this hash isn't all that important a part. Either way, there are still no reliable sources and it's not notable. Phil Spectre (talk) 02:21, 29 September 2009 (UTC)
- Well of course an assembler is not going to make big news about the internal hash functions used, that wouldn't make sense. I am not sure how one would really objectively judge notability, but a quick Google search returns 154000 results. If even 1/10th of those results are unique then that seems significant to me. There are a large number of pages linking to the Wikipedia FNV page, deleting the FNV page would break a significant number of websites. In the Google results we can find mentions at NIST and MSDN.

- MurmurHash was recently deleted, and it has about as many mentions on Google, so that can't be enough. The precedent is that you need reliable sources to confirm notability, not just tens of thousands of hits on Google. Phil Spectre (talk) 11:17, 29 September 2009 (UTC)

- Keep as per discussion with original proposer above. Both the Wikipedia page and the original source pages are mentioned and linked in too large a number of significant websites for me to consider the source as not reliable or not notable. HumphreyW (talk) 13:29, 30 September 2009 (UTC)
- With all due respect, you're certainly entitled to your own opinion, but not your own facts. The NIST link is not a WP:RS, since all it does it point to the same old Noll site, along with the one for MurmurHash, which was deleted due to a lack of reliable sources. If it doesn't count for that hash, why should it count for this one? The MSDN link is not only a blog, but it contradicts WP:N in that the MS employee states that MS has no intention of ever using FNV, and the comments from the peanut gallery point out FNV's terrible avalanche characteristics. If you want to keep it, you absolutely must prove its notability with reliable sources. Fortunately, this is not a vote. Phil Spectre (talk) 22:59, 30 September 2009 (UTC)
