Bitcoin lasts technically till at least 1 valid copy of the blockchain exists, once thats gone... its goodbye to Bitcoin forever.
Technically yes. But Bitcoin is strong only as long as people will be willing to use it. If they one day find another way is more efficient - bitcoin will be done for. It only exist because it is worth something for people. I know that, all I did was just answer OP's question on a very technical level =) Your reply really apply's more so to it actually being worth something and having a market price. But, alas, the protocol & network exist as long as 2 people participate in it, which would be the closest to its 'bitter end'. |

Bitcoin / Wallet software / Re: From holder to spender....

I've been a BTC holder for about a year and a half but I'm such a miser that I've never spent any of it. An online shop I want to place an order with accepts BTC so I'm ready to take the plunge. I'm thinking an Android wallet with a small balance makes sense. Any recommendations for that software?
I also don't want everyone I spend BTC with to know my main account's balance. What is the best way to prevent that from happening?
https://play.google.com/store/apps/details?id=com.mycelium.walletmycelium is amazing, tx's are lightning fast, its interface is super lightweight, responsive etc..., it even works w/ HD wallets now and has a very good built in backup mechanism. Ive used it quite a bit. Never hurts to keep a few of ur spending btc in that wallet. Even has a local trader functionality where u can look up people around u for buying / selling in person and u can easily become one urself =) |

you can't download the 34Go of the blockchain ... in 3 hours.  you can't recreate the bockchain order in that time, too ... on a "normal" desktop or laptop (even with an SSD). it says "AS LITTLE AS 3 HOURS" ... it doesnt say 3 hours guaranteed |

Bitcoin / Hardware / Re: SP20 fan noise.
|
on: February 12, 2015, 03:38:36 PM

The noise of the fan on the SP20 is 90% the fan itself, very little of the noise is caused by the grill.
Instead of drilling the case why not take the fan out and run it outside the case, listen to the noise, and then you can decide if hacking the grill to bits will actually be worthwhile.
You can replace the fan easily enough with a slower less CFM model and run it from a molex converter plugged into the PSU, you are then just limiting the speed at which you can hash at because of the cooling power of the replacement fan.
Also, its probably the acoustics of the SP20 itself that causes the fan noise to be amplified. Its pretty much like a mini echo chamber. |

For the SP20, don't get PCIe connectors start to melt when you are running them? Arent they pulling 300W each?
Wasn't this a huge issue with the KNCMIners in the past and it was a fire hazard.
If ur using a quality PSU the gauge of the wire will be large enough to allow around 300-350w. Also the PCIe 6pin connectors are rated by molex up to 23A, for 12v thats 276w ... so yeah the 288w setting on SP20 is pushing it. I think most electronics ur allowed a 10% delta far as safety goes. So, that gives u up to 305w safely on a 6pin PCIe connector. Also, it would be nice if these manufactures that want to push limits, start using the 8pin. That can handle more current. Also, if using the molex -> PCIe converters, those will for sure most likely melt. One of the grounding holes is left blank, Im pretty sure that causes more stress. Also the molex cables themselves cant handle that sort of current. Im sure people have done this in the past and it lead to fires on bitcoin ASICs |

Yes, I am sorry. I also have pending pull request from Luke which is probably good, but I do not have the time to make the integration (with all the release cycle, and testing on all the miner flavors). Especially in the web, which is not my strongest side, I am reluctant to change things  But developers are welcome to do custom builds, and develop their own flavors if they feel it is interesting for them. Zvi, there's no reason to say "I'm sorry" In my opinion the code repositories should be used interactively. Some of the guys here are addicted enough to even code stuff for you (web or not), but unfortunately they can't integrate their stuff in the mainstream. That's why 2112 suggested a step back from day to day issues and look back in with a bigger perspective. You have a unique position being on the team since the first SP-T chip was being created. Since SP35 is almost out of stock, with the new chips (if any) one can try a new approach. It will be a pity to use the same (or slightly modified) chip optimization model since the SP10 units From a personal perspective I know it's hard to break routines and take new challenges when there is a multitude of small issues to be solved. However, those issues will always be there. Sometimes I'd like to code stuff instead of driving my team to do the coding Particularly when the team is small and busy. But they need guidance and planning while they do what they do best: code. They can't be efficient when they focus on both current issues and future planning. Someone needs to do the planning for them It's the "management" job security paradigm  With the continuous increase in the number of SP-T models, just testing new firmware versions for all situations out there will eventually stress your team more than it can cope with. If I were you, I'd drop support for older models (I'm still happy with my SP10 running FW 1.5.8 and I'm not looking to upgrade it any longer). That will let you focus on the new ones. Also, try an "agile" way of running things. Let your guys focus on the improvements with the largest impact and with minimum work-hours .. the R&D supporting the firmware using the future line of chips should be one of those. By the way, no one needs a weekly FW update. It can be bi-weekly or even monthly. There's no time to upgrade and monitor the units (particularly in large numbers) for improvement, that quick. What it really boils out of it, is to sort out priorities, communicating the sort result to the team. And one can't do that properly when (s)he's always busy with small stuff. I believe that the fw logic is very close to optimum. Despite some things said here i have mathematical background, and i took part in both asic interface definition and implementation. i use greedy algorithm for finding the optimal working point not because it is simplest but because i believe it is best for this task. And i did some simulations and tests before reaching that conclusion. I see no point to rewrite any of the existing fws since i dont believe it will give higher performance by more then a couple of %. I would be happy to be proven wrong by someone from this forum ) How about letting us have direct control over clocks & voltages?! |

But is it worth it? How much would you gain? If it's less than 5% then it's not such a big gain...
"Worth it" to whom? To GenTrakin personally or to the Spondoolies' Corporation and their future industrial scale mining operation partners? 5% may be nothing to a piker but the same 5% yield improvement at the industrial scale means megabucks. It would be worth it to me, 5% improvement in efficiency when its hard enough barely breaking even... is all the difference. |

Edit: What they said ^ I think the above was just Spondoolies-Tech's slightly unsubtly way of saying: Hey, our software is open source. Here's our git repository. Feel free to fork it, make changes - such as the suggested Nelder–Mead approach for N-dimensional optimization, and submit pull requests, and we'd be happy to review the changes and possible integrate them into our baseline - or you can provide your own custom builds for users who would be interested in it. Code repositories are generally not intended for end-users My not so subtle response to this: Spondoolies hired a single junior/young software developer who had landed far out of his depth with regards to state-of-the-art of the optimization of rather complex analog/digital system. His attempts at one-dimensional optimization problems when searching for the optimal configuration parameters show that he isn't aware of http://en.wikipedia.org/wiki/Golden_section_search known since mid-1950 or mid-1960. And various folks here already started to request optimization in 2 or more dimensions. This is going to end up rather badly with regards to the software quality when the corporation gives his lead developer no time to actually research the problem space. Instead they gave him a mishmash of tasks from the request list that are rather trivial and cosmetic. So my friendly advice to zvisha is: step away from fulfilling trivial maintenance requests and broaden your knowledge with a quick peek into gradient-free/derivative-free optimization methods that I've mentioned. The payoff to him (personally) and the company and its user base will be much higher. My not so subtle advice to Guy: you'll need to give time to your staff to do an actual research as opposed to bogging them down with constant development and maintenance requests. Your company's current work on finding the optimal operating point for your miners is equivalent to the state-of-the-art around World War II. Either give zvisha some time off of D and let him concentrate on R (from R&D) or hire a actual mathematical optimization consultant. This should be quite easy in your location in Israel. I actually don't care if you open source it or keep it as a closed-source module that controls the cgminer through its API. You could probably then charge extra for it or differentiate your product from the competition in marketing. The above was a free advice. If you don't like it just ask and I will give you a full refund of the money paid. I agree, just watching how the miner behaves when I specify a working max Wattage, my units are clearly not getting the best GH/W possible. Like I said, they clock themselves down for no apparent reason... Also, an error rate of 2% is acceptable, these things allow virtually no errors, which I believe is the reason for the aggressive declocking =( I bet I could hand tune clocks / voltages statically better than their autotuning does... |

u all must not watch the hashrate of them for the first few days, they go down a good 1-3GH / day.
I have 4 SP20's...
All of them run under 100C
I do know for damn sure if we could custom tune the frequencies these run at they would be much more effecient!
The BIST is far too agressive, at the first sign of a HW error it declocks them like mad. Its ok to have a few HW error lol!
The firmware behaviour doesnt try to get the highest / stable clock at a given voltage unfortunately it seems.

I see 2.6.12 is now available so am downloading it to see whats new. hopefully some further abilities are added to scheduling
EDIT: 2.6.12 made my system think its an SP10 and cant start mining, the fan revvs up and down every few seconds
EDIT 2: went to change back firmware, clicked manula selection, my only options are 1.5.8 and 1.5.10. The Sp20 now seems to think its an SP10 - what do i do?
EDIT 3: used SSH, typed "echo SP2x > /model_id; echo SP20 > /model_name;" and was able to get the device to download the 2.6.12 again, this time operational
2.6.12: seems like theres a wifi function (requires dongle, presumably in the system's USB port). no visible changes or improvements to scheduling though. For that reason im curious to know how changes to the /etc/mg_custom/mode are implemented. Is a reboot required, or just restarting the minergate process?
seems like it could be easy to create a cron task that simply copies different mg_custom_mode(day) and mg_custom_mode(night) files to the actual mg_custom_mode and then re-initiates the miner. It would allow better fan control and precision tuning the voltages and wattage limits for each schedule, rather than just the max voltages
a bit confusing... is that custom day/night your mod or did it come with V2.6.12? 2.6.12 doesnt add anything to the scheduler, it seems to add only the ability to use a wifi dongle my above posts about custom crontab are not part of the newest FW, and should work just fine in 2.6.1 and possibly much earlier firmwares The wifi dongle ability has been in a few releases now... unless theyve broadened compatibility or something that is... |
