P != NP

Someone posted this in a thread on the imageboard and I thought it deserved a thread here:
An HP Labs researcher named Vinay Deolalikar claims to have a proof that P != NP.  His proof is available here:

I can not access the file either online or by downloading it (the download is corrupt).  Do you have an alternate source?

Crackpots post proofs or this, and proofs of the opposite, every other day.

We already know that P != NP is true for all values of N other than 1.

Try this:

It'about 100 pages long.

It looks like a legitimate attempt to me.  He has published in peer-reviewed journals in the past.  I was hoping someone here would actually have some insight into whether or not it is legit.

>>6
It's not.

>>7
Please elaborate.  I'm genuinely curious.

Original thread is still alive here btw:
>>>/sci/1564878

What is this silly bit of algebra and why should we care.

>>10
It has a lot of implications and practical importance. However there are doubts about the proof presented in the OP.

>>11
Be specific, please.
