Password Cracking System

Yea... Sorry it is just true. I was hanging out with D3ad0ne at a recent SANS conference then he unleashed the monster below on me.
I have to say that I felt a bit dizzy just thinking about the specs for this monster. The biggest shock was that it was cooled not my water, but with Chuck Norris's tears. Sure, the damn things cure cancer, but D3ad0ne uses them to cool his password cracking system.
Below is the insane email he sent me with pics of the beast.

Hey John, You said to send you the specs on my super hash cracking rig. I call it Erebus after the Greek god. So lets get down to the stats:
Motherboard: EVGA SR-2 Classifed
CPU(s): Two Intel Xeon x5650's, 24 total cores
GPU(s): Six EVGA GTX 480 Hydrocopper, 2,880 total cores
Memory: 12GB Corsair Dominator tripple channel
Harddrive1: 1TB drive dual boot Ubuntu/Win7,
Harddrive2: Two SSD Corsair C300 128GB drives in raid 0
Just FYI stuff:
The system is set up to be versatile running dual boot Win7 64 and Ubuntu 64. With 12GB and 24 CPU's I can run a dozen virtual machines for testing in a lab environment. The SSD's have gig's of rainbow tables, and dictionaries for use with cracking hashes. Using Cryptohaze GPU rainbow table program I can find hashes in the rainbow tables within seconds thanks to the GPU/SSD combination. Mostly I use hashcat or oclhashcat. Oclhashcat is able to utilize both dictionaries and bruteforce separately or at the same time including rules, all on the GPU, It is also one of only a few tools that is supported in both windows and linux as well as being able to use both nvidia or ati video cards. For NTLM without overclocking I tend to get around 10.5Billion password attempts a second even with several thousand hashes. The creator Atom is also working on a multigpu version of md5(unix) and currently I am getting 5.5million/sec. This may seem slow but usually with JTR you may only see a couple hundred/sec with this hash type. If I'm cracking something with dictionaries and I want to use a lot of rules, I will use regular hashcat, if I use the -n 24 switch it will utilize all 24 CPU cores 100%.
So far I've spent close to $10K US. But I'm also getting a second shelf with a PCI-E bus extender from a company called Magma. The ExpressBox4 will allow me to install up to 4 more cards, but I only plan on getting 2 more GTX 480's, so 8 in all. Also I should mention that all the GPU's are water cooled, as well as the CPU's. I use a program coded by Atom to allow me to test the GPU's to ensure that the shaders are 100% stable when overclocking. Currently I can run the GPU shaders at 1711Mhz instead of the stock 1400Mhz so a little over 17% over stock. And of course hash cracking speed is based off of the number of cores * clock speed. In total it surpasses 5 TeraFLOPS. Not bad for a personally owned machine. Pictures attached. :)

Chicago Bulls Devastating Injury Can Hurt Early Season Hopes

On Sunday evening we told you about Carlos Boozer's(notes) Saturday evening fall, which resulted in a broken hand, and a likely two-month stay on the injured list.
Later Sunday evening, before an already-shook Chicago area was about to be hit with the worst pro football game since the invention of the pink headband, Carlos Boozer explained just how he mangled his right hand.

As quoted by the Arlington Heights Daily Herald's Mike McGraw:
"It happened last night, probably 5:30-6 o'clock at night, got it looked at right away. I find out for sure today when I saw the hand specialist. I'm going to get it done as soon as possible, so Tuesday morning I'm going in early to get the surgery taken care of so I can start my rehab process.
"It was just dark. My doorbell had rang and I tripped over a bag, tried to brace myself and it popped. I jumped back up, opened the door and my hand was still a little bit numb.
"It was a gym bag. It was a big bag I had first thing over here at the hotel for training camp. I went back to my place, hadn't unpacked the bag yet, came around the corner, running to get the door and fell over it. I'm 265, 5 percent body fat. I'm heavy, man. I guess I had to brace myself and my weight just collapsed the bone right there."

Ouch. At-home injuries are just the worst for guys like this, because nobody believes you. Last summer I destroyed my big toe just walking into a heavy industrial fan, and everybody believed it, because they knew I was clumsy enough to pull off something like that, and don't really enjoy an interesting enough life to hurt it any other way. Pro athletes, even ones as injury prone as Boozer, still get no benefit of the doubt.
How do I know this? Well, based on some research I did in a parking lot Sunday night after the Bears game, the general consensus is that Carlos popped the bone in a thumb wrestling bout with Tom Donaghy (not "Tim," just a guy named "Tom Donaghy"), while James Caan and Rahm Emanuel cheered on from behind a two-way mirror. Should make for an interesting recovery.

How Much does it cost to make a penny?????

As of May 2010, it costs ~ 1.67¢ US (or $0.0167 US Dollars(USD)) to mint a penny, making the face value of a 1¢ penny less than its actual manufacturing value.

The cost of a penny is largely dictated by the materials used to make it. Pennies contain 97.5% zinc, with 2.5% copper to give them their distinctive coppery color. Prices of these metals have risen dramatically, in response to market demands and increasing regulation of mining, which has made the cost of metals extraction much higher.

The obvious solution to make a penny less expensive is to change the composition of the coin, integrating cheaper metals or perhaps even plastics, as is done with some European currency.

However, attempts at changing the composition of the penny have met with some opposition, since some people are concerned that changes in composition could change the look and feel of the iconic American coin, even though in 1943, the US Mint coined pennies in steel, in response to wartime demand for copper.

Others have suggested that it may be time to do away with the one cent penny altogether, a decision which would certainly change the way Americans do business, as well as anger people in the state of Illinois who's favorite iconic President Abraham Lincoln is on the penny.

In addition to the penny, the nickel also has a physical value which is higher than its face value; nickels cost around 7.7¢ US to make. Other currency, such as dimes and quarters, costs much less to make. The face value of a quarter may be 25¢ US, but it only costs 10¢ US to make one. In some people's opinions. The relative high cost to make a penny or a nickel is balanced out by the lower costs of producing the other coins. Still the debate over the fate of the little red cent continues.
