and creator of DiabloMiner, one of the most used GPU miner (although not the most I believe).
Historically its the most, but I've lost ground recently to cgminer... but then again, cgminer offers my kernel as an option.  |

2 questions:
1. How does this 'share swap' work exactly? I transfer you 2 giga via glbse then you send me 5 DMC shares direct to my account, is that correct?
2. Are you taking puremining shares in exchange, and if yes whats the exchange rate?
Cheers
1) Yes, you specifically send it to Diablo-D3:DMC (GLBSE has a weird subaccount naming scheme) and tell me the exact date/time and amount of the transfer (GLBSE gives you those on your portfolio page under transfers out) and then I send you the DMC shares. I also need your GLBSE account name. 2) I'll take Puremining, 1 DMC for 2 PUREMINING seems to be equiv to the rest. I've added it to the list. |

"borrowing the stock increases the supply of the stock".
Excuse me while I run away screaming. |

Update: (Updated 9/10)
Shares sold total: 20909
Shares held total:
54 BTC-MINING (300 mhash) = (16200 mhash)
951 BTCMC (7 mhash) = (6657 mhash)
9290 OBSI.ABMO (12.92 mhash) = (120026 mhash)
Total hashing power: 142883 mhash
Approximately 6.833 mhash per share

Although I'm not interested in a trade, I'd appreciate it if you'd take a chunk out of the Cognitive askwall!
I've added an offer for Cognitive as well. |

Well, you bought relatively expensive on the bitbond end... The current price for 1 MH/s seems to still be 0.3 BTC - preIPO from trusted people you might be able to buy even cheaper.
You could also offer to trade 1 share of your company for 3 MH/s of mining bonds for some time.
A lot of people have BTC tied up in that Bitcoinica clusterfuck, and many people have told me they would invest in DMC but can't because of that, but many people also have significant GLBSE holdings, so I'd like to help everyone out: http://caspar.adterrasperaspera.com/dmc/trade/This seems to be fair to the owners of those bonds and for existing shareholders. I'm willing to pay that small premium just to get (virtual) hash power up to start growing the growth fund and pay out dividends for early investors. If anyone wants to do it, talk to me on #dmc or #bitcoin-assets on Freenode or message me on the forums. GLBSE changes a fee to transfer, so remember to have a smidgen of BTC in your accounts. |

It'd be nice if you could find a heatpipe-type solution so people can put quieter cooling on their rigs.
Also, the URL in your sig is 404.
The main problem in this design for cooling is the amount of space between each fpga card.... You may be able to find a small waterblock something like this: img
So, that mean passive heatsinks wont cool enough? cuz those little fans really REALLY suck, they die nearly instantly LOL...
It all depends on what speed you run the FPGAs.... even with the big passive heatsinks like the Zalman northbridge shown below you still need fans to provide airflow of some sort when running your FPGAs at a high clock speed. with those black heatsinks you see in the pictures, to keep the FPGAs cooled we had to set 2 80mm fans side by side blowing on the FPGAs img I was thinking something along the lines of http://thermalright.com/products/index.php?act=data&cat_id=8&id=106That could almost work, just change the orientation, it should be able to cover three of the chips (one on the left, one on the right, one on the top) and the very front one could just use a http://thermalright.com/products/index.php?act=data&cat_id=8&id=107But thats like $200 worth of heatsinks, but it also might not need fans. Edit: http://ultimatepccooling.com/thhrifxchco1.html $28 http://ultimatepccooling.com/thhrifxchco.html $27 So, $111 or so. |

Just reporting in that after I upgraded to the latest DiabloMiner, on both my Windows and Linux machines the miner starts as usual.. adding the devices and then hashing away.. However, shares are never submitted. I walked away for a while and saw that in fact no shares had been submitted to eligius. For proof check out: http://eligius.st/~artefact2/7/1AXiiwR4aYktPKMBMsZaP1untDgN9T8FfXEdit: Found an older DiabloMiner and reverted (it does not include the 2 latest commits), back to mining. I cannot reproduce that bug. BTW, I've dropped OpenCL 1.0 support, so if you're on SDK 2.1... don't do that. DM is supposed to detect if you're on 1.0 and refuse to use those devices, too. Well, assuming I coded that test right. I am on Catalyst 12.4 and the SDK that is included with the drivers. Radeon 5870s/5850s in both boxes (CentOS/Windows 7). If there is anything I can do to help you possibly pinpoint the problem I am all ears. Basically diablominer adds the OpenCL devices then starts hashing away at only god knows what.. and never submits shares, all whilst hashing at full speed and making my GPUs waste energy. The hash meter has a number above zero, right? I'm wondering if Windows has a driver bug that Linux doesn't, because I'm on Linux /w Catalyst 12.4 using the runtime that comes with the drivers, and I can't reproduce it. Yes the hashrate is at full speed, causing 100% gpu usage on all gpus. This happens on 2 separate systems, both with catalyst 12.4 and the included sdk. One system is windows and one is linux (CentOS). Thats extra weird. I'm going to have to think about this one for a bit. It doesn't make sense you have the bug and I don't... I wonder if its hardware related, because I'm on a 7970, not a 58xx. |

Angry neighborhood bastard mod here:
Enough with the harassment. If they launch, then they launch, THEN you can make fun of their product lineup.
Until then, let them quietly build their 2U rackmountable rigs by themselves. Hint hint.

So, Im curious will the fpga's themselves come w/ the heatsink pictured? Will this be suffecient enough cooling to perform @ 200mh/s / fpga?
Or will I need to go find HSF's for them as well?
No, We've updated the boards to allow for bigger northbridge / older GPU heatsinks, the new design also includes 4 fan headers. We plan on putting a heatsink/fan combo on each fpga that will dissipate around 25 watts of heat which is more than enough cooling for these FPGA's. Heres some examples: http://www.newegg.com/Product/Product.aspx?Item=N82E16835119079http://www.vantecusa.com/en/product/view_detail/93It'd be nice if you could find a heatpipe-type solution so people can put quieter cooling on their rigs. Also, the URL in your sig is 404. |

Update: I've moved the remaining 136 BTC into split Giga/Bitbond.
I've been talking to a few people who shall remain nameless, and 28nm miner products should be coming out in the next 2-3 months, and it would basically be a waste to order 2-3 BFL singles now when 28nm could be much cheaper per mh.
Current holdings: 79 shares of Gigamining @ 1.51, 179 shares of Bitbond @ 0.655
Not exactly where I wanted to go with this, but its better than leaving the money sit idle.

Update:
235 shares sold thus far.
Its going to take awhile for mining hardware to get here once, so I've bought 50btc worth of Bitbond (76 shares) and 50btc of Gigamining (33 shares) as a short term stand in. Leaves me approximately enough to buy a BFL single to evaluate BFL products.

We're slightly past the 12 hour mark, and 232 sold already.

I have repeatedly told people that Bitcoinica is a scam and that Bitcoinica staff should be banned from the forums.
Maybe now people will actually listen.
Bitcoinica is a regulated entity, verifiable by government records. We are one of the most legitimate businesses in Bitcoin community, by any standard. What is it with all the anonymous/pseudonymous guys on this forum repeatedly attacking every NAMED (and easily verified) individual and company and labelling every project run by those most legitimate operators as a scam? Insane! Grow a brain or something. I'm sorry, what? I am not anonymous. I am a forum moderator, an early adopter, and author of the DiabloMiner software. If Bitcoinica was so legitimate, why did they get "hacked"? The facts simply do not seem to add up. |
