Forgive me if this is absolutely ridiculously stupid.

Let us define P as the problem space which consists of all of the problems that can be solved in PTIME. Let us define NP as the problem space of the which consists of problems that can be solved in NPTIME. We can say P=NP if P’s problem space contains all of the problems that NP contains and no more. Assume that P=NP. Because P=NP, the decision problem P=?NP must itself be a part of the problem space. Because we have limited knowledge of the problem space, we must use a problem generator to complete a brute-force search of the problem space. This is NP-Hard for even the linear search (generating all permutations (problems) of inpu

I picked up these speakers at a yard sale a while ago and am now selling them because I need the money. They have excellent range and sound wonderful. [Here] (http://www.sansui.us/images/Speakers/SP_4Digits/SP4500_1.jpg) is a picture of one from the Sansui website. Mine are actually in better condition than that. I'll provide more pictures when I get off work. Price is negotiable -- I've seen prices online in the $100-$300 range for the pair.

Message me for more details.

I work at a small web dev company that also does email hosting via smartermail. Recently, we've been encountering a problem in which spammers compromise email passwords and subsequently send out massive numbers of emails which results in our servers becoming blacklisted. We are using barracuda networks email security to curb the problem, but it has thus far been ineffective.

Does anyone have an idea of how to prevent this kind of attack?

I'm a Computer Science researcher and gun enthusiast that happens to have a 3D printer (ABS or PLA capable). Does anyone with more gun-knowledge than I have thoughts on the current limitations of ABS 3D printed weapons parts? I'm especially interested in the prospect of 3D printed magazines. I own both a Saiga 12 and an AR-15 (though not hurting for mags on that one). I'm capable of 3D printing a magazine, but I'm not sure how long it would last, or if it would even be worth it. Also, I'm in Alabama so no legal concerns as of yet with regard to magazine capacity. Thanks!

edit: TIL clip vs. magazine. I've always used them interchangeably.
