Speculation.
1. Here is specs of our new 28nm generation chips. Order page is here.
2. We start shipping rest of the chips today. Compensation will be paid for delays as credits for new chips using this formula based on delay.
3. You can request refund for your batches, but they are not guranteed to go thru. i.e. we can only refund a certain number of batches.

Great work burnin. One question for you.
I paid in advance for more then 30 boards. If my avalon chips dont show up really soon, I will have to ask for a full refund from you.
What is your refund policy?
I asked the same thing via mail yesterday. I'm still waiting for an answer. I'm going to be honest, I think you'll have to share the burden of Burnin's financial loss. He didn't deserve this, and you and he all thought it was a sure bet, no one forced you to buy the chips and you all chomped at the bit to have someone create the products around them. I don't see why he should be out into financial difficulty or bankruptcy because of Bitsyncom's behaviour and lack of integrity. Burnin's has been Stella and transparent the entire way. If it was a Credit Card payment the issuing bank would have insured the loss, but to ask for him to find the money to repay everyone in BTC, which would have been used to pay for inventory and already depleted is not fair. Certainly he could give a partial refund covering the remainder of BTC once his costs and time have been taken... I admire your honesty, but who da.fak are you to talk about burnins financial loss? I paid in advance for 700 chips and got fukd by Yifu the man, and paid for 30 boards, again in advance. The way.i see it: no chips = no preordered boards = no financial loss for burnin. 30 boards = 3500 € Ok I'm just taking a logical standpoint. Burnin' has been the textbook professional with respect to project progression and updates, regularly keeping all those involved with him upto speed. He had to take payment in advance so he could quit what he was doing before, afford to live and pay for all the inventory required to design, develop, test and manufacture all the boards and associated components ahead of the proposed chip delivery. He's had to pay in advance for the labour involved and a sizeable order to be taken seriously by his board fabricators. He now has those items in stock. You asked, he's done his part, it' involved your cash and everyone else that put him upto it. You all, Burnin' and yourself included thought it was a great idea. What could go wrong? The last people in the supply chain that anyone thought would intentionally mislead and refuse to acknowledge anyone was Yifu and Zhang. This is not Burnin's fault and I see no other choice than for your to take responsibility for some of your own risk if you chose this path and a payment method that's not covered by consumer protection and insured by a credit card issuer. I'm all for Bitcoin, obviously I wouldn't be here otherwise, but there's areas I'm which would never use Bitcoin for pre-ordering, and payment protection is just that. This is not Burnin's fault and it's as much your risk as his. Sorry if you don't want to hear that, but you have to take responsibility for your own actions and not try and dump the blame on someone else... +1 agree I paid burnin to build boards out of ASIC chips that im supposed to send him. If (for whatever reason) I cant send him the chips, then its me in violation ... not Burnin. He may have spent most of that money with securing components and equipments for speedy fab which we expect from him. In fact burnin can, if he wants, ask for penalty cause now his entire scheduling is messed up cause of my failure to provide him the chips.... but he wont do that since hes a nice guy. |

One advice for managing git: Use a single branch as your main branch (typically master). Then use other branches for experimental features or work in progress. Then once you would like the general public to use those features merge that branch to the master.
This way, for example you push the change to "fasterstarup" while work in progress, ask more savvy people to try it out on different platforms, once satisfied then merge to master. At this time the general population including fresh users get this. This also means people who cloned master in the past just need to do a pull rather than checkout an alternate branch .
Changing the main branch on github is a little disorienting.

Last night benchmarked on cc2.8xlarge EC2 instance ( 2 x Intel Xeon E5-2670 processors) got ~35 h/s Thats 16 physical cores, 32 threads Thanks - looking at this and the i5, I'm concluding the bottleneck is at L2 Cache - having about 2MB available per thread is ratio to aim for. Now, if my calculations are correct, at current difficulty, 0.00028632, each hash represents about a 1 in a million shot at solving the block. Your EC2 instance is giving about 35*60*60 = 126,000 hashes per hour - you'd expect to solve one block every 8 hours. To calculate the current cost of mining a block, what's the lowest price Amazon does that type of instance for? (I had a look at their pricing, but couldn't work it out) I nuked the instance after an hour... but.. its currently ~$0.253 / hour on spot. note 8 hour is the maximum time taken to try out all possibilities for a single block. A block could be found sooner, other users could find a block in meantime needing a restart... Taking your 8 hour estimate, for EC2 mining to be successful, a single block needs to be worth > $2.024 at current difficulty. Another thing i noticed was while mining, the memory usage for bitcoind was swinging wildly from couple of megs to > 1 GB . Is it possible to allocate memory once and re-use that? I think a lot of time may be wasted in memory allocation and subsequent garbage collection. Is there some documentation about the hashing algorithm used? (Sorry im not fluent in reading c++ code) |

http://www.dwavesys.com/en/dw_homepage.htmlPrice tag of only $10,000,000 and that's probably old tech now since it's commercially available. Bitcoin is already vulnerable and has been since it was created. Consumer products will probably be out in 2020. Not. Eventually if it does become a problem, you do something against it, same thing happens with pirating, the gov will never stop pirating, nor will quantum computers or anything of the sorts stop bitcoin  AFAIK the most advanced quantum computer today can only add 2 digits where the sum is 7 or lesser.... It wont be like one fine day you would see physicists come out and announce "Today we have built a quantum computer advanced enough to do double sha256 and mine bitcoins @ 1 gazilion PH/s" .... Im pretty sure before then, quantum computing would become common in day to day life for simpler tasks... and the algo would have evolved taking that into account. The risk, if there ever is one, is not from the mining aspect but rather from quantum computer being used to crack private keys, but im certain devs will adapt to stronger key algo by then. |

anyone get multi-threading in linux to work? I can compile/run, but then cannot connect to the server via the daemon command. Very odd
ok it seems like deleting my .memorycoin folder fixed this. However, only 1 CPU core is being used ? Are you using the multithread branch from github? Yes - this coin keeps barfing on me. Just got a seg-fault when running it with multi-thread. Can't connect to server... blah blah blah. More work is needed here The multithread branch from github worked for me without any fuss. the "cannot connect to the server" thing will last for few minutes with bitcoind taking 100% cpu thats normal. i assume thats the daemon trying to validate the existing blocks.... launch the daemon, wait for the cpu usage to stop. then the daemon will respond to rpc. |

This coin is really hard to mine. It takes literally hours to load the bitcoind and download the blockchain..
I think he made the hashing algorithm so hard that even verifying work takes forever.... |

Is it typical for "bitcoind" to take 100% cpu of a single core while downloading the blockchain?
This is on linux btw... whats the current block count?

i download memorycoin3.zip
then type addnode 180.183.205.59 add in the command windows
but still cant sync
Network is currently under attack. Don't download any binaries or add nodes until the attack is over. I'll let you know when. it no workie -- tbh I think you should restart the coin. It was too flaky at the beginning. +1 for restart. This time with proper sources and makefile. and fresh fork from bitcoin ... not dumping loads of bitcoin changes in one commit.. which is too much work to skim thru to verify if everything is legit or not. |

If Yifu Doesn't deliver them till the end of this month he shouldn't bother to deliver them at all.
If he deliver all in same time that is 350Th 275Th+350TH = 625 Th ---> 90 mil... So only if he deliver slow some of us can ROI.... If deliver all in same time we all lose money. Translation: If he delivers slow, some people will ROI but most people will loose all their money but he he delivers all, everyone will loose some money. |

The entire bitcoin mining "industry" can only generate 1.3m BTC a year, and that's only until the next reward halving in a few years.
With bitcoin at $100, that's just $131 million a year.
Anyone investing $200m in mining at this point is either a complete idiot, or thinks the price of bitcoin is going to skyrocket. Or doesn't exist.
I think non-existance is the most likely possibility here, I doubt there is any $200 million dollar deal, and there isn't even that much of a difference between 20nm and 28nm.
They may not be after the BTC themselves but rather after the miner's money  I dont think this is credible news btw, look at this: http://www.feld.com/wp/archives/2011/01/avalon-ventures-raises-a-new-200-million-fund-and-gets-a-new-website.htmlDoes anybody else think the authors got confused here? Good find. No. I dont think author is confused at all. Hes simply Trolling.... Nobody is that dumb |

BoT saying saying something is not legal (assuming they have the right to decide on such matters) only has implications for businesses who want to mention BTC transactions in their books. For it to be "really" illegal for the common man, they need to publish a ruling saying so, send notifications to relevant authorities to enforce such ruling. Thats just the way it is in Thailand. IMHO prostitution is more illegal than BTC in Thailand. We dont know if BoT did indeed say its illegal or not. The blogpost by the defunct exchange wrote something on their blog (all media articles based off that) doesnt make it law. After days of searching, the only quote I found from BoT did not say anything firm. All they said was they rejected the request for exchange. They probably also told the reporter that they did not rule it illegal, but such headline wont sell newspapers. Has it occurred to you that the exchange's blogpost could have been something lost in translation, or they are just venting out in frustration? |

Avalon® interfaces simplify system design by allowing you to easily connect
components in an Altera® FPGA. The Avalon interface family defines interfaces
appropriate for streaming high-speed data, reading and writing registers and
memory, and controlling off-chip devices. These standard interfaces are designed into
the components available in Qsys. You can also use these standardized interfaces in
your custom components. By using these standard interfaces, you enhance the
interoperability of your designs The very first page.... What part about that made you think that this Avalon is even a chip? Even if so then what does "streaming high speed data" have to do with bitcoin or SHA256? |

I don't think anyone has asked this yet. the starter kit comes with a raspbery Pi, are you just running regular software on that, like cgminer? or, is it running something proprietary? Can the MBs be connected to a regular PC via usb?
Nothing proprietary just cgminer but it uses a SPI interface. You would probably need some kind of SPI controler for PC.... |

10Gh/s = 30 Usb-Stick-Erupters.... But Thailand.... Well... I guess the shipping costs would be < $100 both ways especially since i wont include power adapter or heatsinks (updating OP) |
