For the GUI I'm still not settled on a GUI framework. What ever I choose I intend for all of it to be cross platform of course. I may also make a web front end? Make the browser the GUI. Doing a GUI any other way is not so portable plus they always require all the extra gui packages, etc. Everyone/everything has a browser already. And keep it simple so command line tools can use it too. |

I have read that the smaller-size/lower-power curve of FPGA ends with 28nm. So it seems that the 28nm designs are going to take more work than in previous generations. Is the sha-256 code required simple enough that the 28nm design won't provide new stumbling blocks and/or increase time-to-product?
wonderminer,
Were you able to get 75MH/s on a de0-nano or is that just a theoretical number? Is there a git repo somewhere?

The hours is at max rated temp. Rule of thumb is that for every 10 °C lower it doubles the life expectancy.
Only double for 10C? I don't know much about caps but my gut thinks it would increase life by more than double. Hopefully they are not like those infamous caps in the iMac-G5 |

Peltiers are cool and handy, but for big mining operations phase-change heat pumps will be FAR more efficient. Remember that Peltier modules consume a lot of current and act almost as 200% efficiency heaters on the other side  How would a phase-change heat pump work for cooling a chip? Is there an off-the-shelf device? Or would it be DIY? For the peltier I realize power is needed and heat is also produced but if your goal is to cool the chip it would work for that and peltier makers target this application of their products. e.g. micropelt Perhaps a better way to efficiency is to create your own cheaper power and don't create as much heat by running miners at lower freq. |

Guys, how many of you received their equipment? Is this company reliable or is this another scam? I would like to order few basic platforms, but I do not know if they can be trusted.
Guess it depends on your definition of scam, they seem to be trying to run a legit company. The question comes down to "How much risk are you willing to take?" My concern is that they are selling a one-trick pony. From what I've read they use an encrypted bitstream and, if I understand that correctly, that means only BFL can provide another bitstream that would work. Also there's the issue of the unknown hardware that they use. It seems that they bought the chips (stratix?) at some reduced price which suggests that they have some number of chips but can get no more. So 6 months from now when yours has an issue you're out of luck if it's the FPGA. That's too much risk for me, 6 month warranty doesn't inspire my confidence. |

Would make it quicker to find fpga discussions. Or maybe a GPU sub-forum would make more sense since at halving-time GPU miners will quit
and the GPU discussions will be less frequent.

Maybe these devices have to be run inside a freezer to successfully achieve a consistent hash rate 300 MH/s and beyond.
Maybe a peltier device would suffice. |

Potential bidders for the IP are altera, xilinx, possibly others (like terasic, etc.) and the BTC FPGA community. I know very little about the fpga market but I'd guess that big players (altera,xilinx) wouldn't see BTC mining as a big enough market but mid-size players that do fpga/asic IP might be.
How do you convince anyone that what you have is legit? You'd have to let them see something under NDA? What if they say "no thanks" and go do it themselves based on what they saw.
At what price will you be content for your investment?

Not like they haven't tried, but as soon as their bank turned them down, no other bank was willing to have them as customer as well.
Then open their owin bank. Why get caught up in the courtroom-death-spiral. |

Have you considered getting a new bank? Seems like you're trying to force a relationship with someone that's dumped you. Move on.

Did you all choose sf.net for mailing list because no one likes it? I'm not clear on the technical details of this but from a higher-level view it seems that the devs should, if not already, think about how to push updates out. i.e. decentralize the software
I'm not sure how to do what I'm getting at but having everyone update, in the way that's needed to implement this change, isn't going to scale into the future.
Has this been discussed already? Some kind of enforcement that would prevent unsupported software access to the network? Am I making any sense at all?
I realize pushing updates out automatically would be unpopular so another model would be needed. Not sure what model would work.

All of this technical stuff is way over my head, but I'd like to share my ignorant thoughts anyways.
It seems to me that 8 days is not enough time for people to really do their research on the matter. If I were a miner, or the operator of a mining pool, I would want to know EXACTLY what I'm doing before I made any serious changes.
Secondly, even if 8 days is enough time there is something unsettling about this. What you essentially have is a few highly skilled coders in the know. If they can dupe the mining community into something, anything, nefarious it could destroy Bitcoin. Obviously, I'm not saying that they will, but posit this:
Imagine highly skilled feds, or any other criminal organization, infiltrated the upper echelon of Bitcoin coders. They spent long hours making it better and building a reputation for themselves, slowly but surely dominating the entire field of coders. Then, one day, it's time to destroy Bitcoin and they issue some sort of scenario similar to the one we're dealing with now, for the mining community to go to a new blockchain or something, and the mining community takes their word for it, and BAM, Bitcoin is hashed forever.
I understand this is conspiracy theory stuff, but can anyone unsettle my fears about this scenario?
You might as well throw out the label "conspiracy theory". History, long past, and recent, has shown that discerning minds often reveal the truths behind events. So don't let lesser minds diminish accurate perception. What inspired BTC? Bored geeks? Current world events? Recall the debian ssl "issue". It can happen here too. What did the spooks talk about with Andresen when he went to visit them? Oh and have a look at github notification about recent security breach. Isn't bitcoin code stored there? The question is not if but when. The spooks always have a control point. They don't rest until they do and even then they hedge because that's the game. |

Shows a major weakness in linode I'd say. Other linodes were hit as well. I would be saying goodbye to linode. Since they seem to be short on details we can't conclude anything, except that they're system is flawed. They need to have failsafes in place.
What could you have done to prevent this? Would an encrypted wallet prevented this? Multiple wallets? It may help a lot of people to discuss how to make it harder at least.
Stealing BTC might become more profitable than mining or maybe it already is, the crook had to give up an 0day possibly?
Would be nice to see linode present an in-depth analysis if they can't cover any of your losses.

I'm quite aware of 3D printing, and have followed it since it started with modified ink jet printers years ago. How long do you think it will be until we can print something like an iPad at home from scratch?
Before modified ink-jets they used a laser, to initiate polymerization in a bath of polymer, at the surface. With the $$ that apple makes in ipads wouldn't expect that to happen soon. But I have no idea. With MEMS and other tech. like that it's conceivable that it goes past the printing paradigm and goes to a programmed additive engineering. Probably already a clever name for it. Similar to how a gene codes for an elbow tendon. Only all done via nano-bots. nanotech seems to have bored most people but it is likely the most disruptive tech. right now. It allows control of synthesis in amazing ways. Going a little astray. Shipping things all over is very wasteful. But apparently tptb like shipping. I always thought that shipping music,movies in cds, dvds etc. was so odd. Why didn't they just have a cd/dvd burner in a shop and burn a copy on an as-needed model. Now they wanted to retain control of the IP so shipping was their answer I guess. But they could have saved billions by having a cd/dvd burning kiosk that was physically secured. My long winded point is that the politics of any large project is so complex now that tech. can leap over the initial idea. |

i usually get 800-1200ms here.  You may want to try p2pool. I couldn't tell you if it will help you or not. If you check the p2pool thread someone might be able to tell you more. I am guessing you're in Asia or maybe you're on a sat link. |

1. create a description of what the marketplace wants
2. model the description over time, BTC-time, i.e. what happens to the model when reward is halved, etc.
3. decide what pieces to use
4. don't get diverted into developing new buses or protocols, make do with what's here now
I am only learning about hardware, and FPGA technology, specifically. It seems to me that the best approach would be to allow a system to be expanded as it is affordable.
Have you seen schmartboards? Maybe purists scoff at that? I may misunderstand schmartboards but would it be possible to buy FPGAs and add them using schmartboard in a sort of expand-as-money-becomes-available scenario?
Maybe there is a modeler out there already? For example I have no idea how much bandwidth is required of a miner. How many FPGAs can share a 10Mbit connection.
Just throwing out thoughts/ideas.

Tinfoil much? An SEC filing is a legal document, if it is substantially incorrect then Google would have some 'splainin to do, Lucy! and they would be paying some massive fines to the government.
Name calling, too funny. You probably believe in unicorns too. Yes the SEC would never lie nor would google. Believe what you'd like. I'd bet you don't know too much about the current world financial events. If you did you'd find it hard to believe anything about the stock market or wall street. What do you think is the motivation behind BTC? Don't answer that, it's rhetorical. Believe in any fantasy that you'd like and like I said make sure and put all your data on google's servers like a good citizen. State sponsored capitalism = facism |

This poses the question: is NFC actually a strategy to institute a system whereby all communications (especially financial communications) can be tracked (by institutions that don't have your best interests in mind).
(I don't even know what NFC is) Everything's setup so that you can be tracked. Why would they not do this? Because they don't need the extra control point? They have enough already? |

Advertising. En masse. It is 97% of their revenue, and making it targeted is in the interests of the advertisers.
