Love the effort from the guy but I think we all know that it is going to get leaked without the commission at some point.
Same with digital copy of magazine ...
Piracy in inevitable. I think he should have sold it off initially rather than take a constant 5% cut but that is just me.
He states in his FAQ that it is possible to reverse-engineer the bitstream from the device, but that the effort to do so would require as much or more knowledge of how it worked as it took to create it in the first place, and therefore the effort would be best directed at just creating it again from scratch. And assuming he is using robust proxies like he states he is (google and amazon), that makes the DDoS a bit less feasible. Finally, if he is using proper open encryption techniques that have been proven, and not falling into the trap of "roll-your-own" failure, it has a very likely chance of success. |

Note to RJK, set a rule in your next auction to only allow people with X or better rep.
I set buyer restrictions, but as far as I can tell I can only disallow users with fewer than zero feedback. I need to look into it again. Is this the board that allows you to run 13 GPU cores?
lol no, it has seven PCIe slots, but you are still limited to 8 GPUs from AMD. You can however exceed that with nVidia Quadro equipment. Sorry for the late response, I forgot to enable email notifications on the thread and forgot about it.  |

"Market share? What's that? What do you mean? Android is doing amazingly well in marketshare. It essentially caught up to Apple despite a 5 year headstart and competitors RIMM, Palm, and Windows mobile dead or dying. Second isn't quite like first. Unfortunately the "Jesus phone" has a cult following that will be difficult to actually uproot.EDIT: Nice edit, I see the graph now. Wow, it's farther along than I thought it was, and hopefully that trend continues. |

Asus P6T7 WS SuperComputer motherboard LGA 1366 socket with all the overclocking goodies in a workstation board - this motherboard will handle 'most anything that you care to throw at it! The pictures show my system with the board installed. It was returned for RMA, and has not been installed since the new replacement was received. The waterblock shown in the picture is not currently installed - this board comes with the stock heatsink! This board has DUAL ethernet ports for failover reliability, and dual SAS ports for enterprise storage connectivity. There are six (6) DDR3 memory slots for triple-channel speed. Please note that this listing includes only the motherboard itself with the stock heatsink. It does not include memory, processor, hoses, or fittings. I'll include as many of the original accessories as I can find. Selling here because some idiot 0 feedback ebay buyer didn't pay. Asking 33 BTC including shipping to the US and maybe Canada, if it's cheap.    |

Well if they have access to wafer chip manufacturing, then why would they manufacture FPGA when they can do ASIC ?
I think more likely they got a good deal on these chips somewhere.
I remember guy with Extraordinaire rig, had a part that was advertised for $2k officially, yet a phonecall got it for $600.
LOL no not quite. I meant ringing up Altera and saying "Yo, we want 10K chips, start the foundry pls" And my board was bought on eBay, that's how I got it cheap.  |

Things change.
One of the next upcoming changes is a huge difficulty spike and FPGAa becoming irrelevant because of ASICs. I'm pretty sure that eldentyrell is going to make LESS from this scheme than if he sold it outright. But we will see. Personally I'm hoping/speculating that that won't be for atleast another year yet. I think this is the perfect subject for a bet. Does anyone have good ideas for a bulletproof statement that we can gamble on for this? |

Even if there is a jurisdiction where a legal issue arises, isn't the logical answer just to not sell in that jurisdiction? If I'm the president of Zimbabwe and make video game depictions of birds illegal, does the world lose angry birds? Maybe it's illegal in the MC/Visa jursidiction?  Another good point…and it makes me wonder if there aren't already other apps that are in fact illegal in some jurisdictions and for which Apple has allowed, but disabled just in those jurisdictions. Steve, your stuff runs on iOS doesn't it? Has it been subject to any limitations? |

It should be port 9332 also if you want to connect miners from outside and allow other to see your stats  Rav, I'm confused, post #3 in this thread (step 9) is listing 9333 as the port to forward. bitcoind is listening on 9332. Should I be opening 9332 not 9333? Did they mean to open 9333 and forward it to 9332, OR open 9332 and forward it to 9333, OR open 9333 and forward to 9333, OR open 9332 and forward to 9332? What do you have in your setup? Thanks, Peter bitcoind uses 8332 for JSON-RPC and 8333 for peer connections, and p2pool uses 9332 for RPC and 9333 for peer connections. You should open 8333, 9332, and 9333 for a public setup, but not 8332. For a private setup, just open 8333 and 9333. |

If not, what combination of components relate to the speed loss? It seems to me that they way to speed it up would be to use a very fast processor, very fast RAM, and lots of RAM - more than 64GB to start with.
I'm sorry I probably wasn't clear enough. The classic programming language compiler has the CPU architecture stored in the back end and it is always the same no matter whether you compile short or long program: in the end the RAM is linear. The HDL programming language compiler also has to have the FPGA architecture stored in the back end. But unlike RAM the FPGA is not linear, it isn't even rectangular. Remember reading the complaints of eldentyrell and bitfury that the LX-150 has some things missing in the middle of the chip where it has the global clock buffer? Well the back-end of the design compiler (place and route) has to read in the detailed chip resource layout: SLICEs, BRAMs, DSPs (all those are explicitly documented) as well as undocumented switches and routing resources. Not only it has to read in all that data, in the place and route stage it has to explicitly fit the design into the floorplan. Even if the toolchain is all running from SSD disk it will still have to do those tasks. And those tasks aren't linear, the slowdown from LX9 to LX150 will not be 150/9, it will be noticeably more. Right, but I'm still not sure from that description where the bottleneck is - like I said, there are always ways to speed anything up, even if the speed difference isn't a lot. For instance, if the CPU doesn't actually relate to how long such a design placement takes, you could save money there and spend it somewhere else - for instance, on a 24-drive SSD array.  |
