Hi, As far as I understand it, Elliott's $100 combines with the $5 entry fee of every person who participates.
Assuming www.elliottkember.com stays live and one person joins the hunt every week for the next 1.36038980860568e+22 years then that is a lot of money, even counting inflation. Now, if Elliott invests that money in a high-yield share portfolio making 8% a year over that many years, and still pays out the total (ignoring the interest), then he is a very rich dead man indeed! I am not even going to try calculating the compounding interest on that... -Stig Nathan Kennedy wrote, on 8/05/2009 9:39 AM: > I love this stuff. > > Ok, so I did some quick calculations: > > In one of my virtual machines (2.33GHz dedicated CPU) it took 12.6 seconds > to loop through and calculate 10,000,000 hashes. > > Being that there are 16^32 possibilities, it would take the follow amount of > time for my wee VM to try all possible hashes on its own: > > Seconds: 4.29012530041888e+32 > Minutes: 7.15020883403146e+30 > Hours: 1.19170147233858e+29 > Days: 4.96542280141074e+27 > Years: 1.36038980860568e+25 > Decades: 1.36038980860568e+24 > Centuries: 1.36038980860568e+23 > Millennia: 1.36038980860568e+22 > > Assuming that my calculations are correct (I just threw them together, so > errors may exist), you would want a few million machines doing the > processing and a central distribution point to make sure that work isn't > being repeated. > > With inflation, I wonder how little the US$100 will be worth in > 1.36038980860568e+22 ish years? :) > > Thanks, > Nathan > http://www.kennedytechnology.com > > > > > -----Original Message----- > From: [email protected] [mailto:[email protected]] On Behalf > Of Elliott Kember > Sent: Friday, 8 May 2009 6:47 a.m. > To: NZ PHP Users Group > Subject: [phpug] Some fun with MD5 > > > Hey guys, > > It's been a while since I've posted on here since I'm living in the UK > now, but I thought I'd tell you all about a project I've started.
