Want to demo mining to kids for educational purposes (plz dont spam on its not worth mining with old rigs bla bla - this is a tech issue, i don't really need to mine a block): I setup latest bitcoin core 14.2 full node on a win7x64 machine with correct bitcoin.conf settings for solo mining (tested with bitcoin-cli) I setup latest 5.4.2 bfg miner (64bit) I plugged in my old BFL jalapeno ASIC box (dusted it off) - win7 installed drivers automatically from win update correctly (COM14). ran BFGMiner (according to BFGMiner readme example for solo mining): bfgminer -o http://127.0.0.1:5252 -u asdfasdf -p asdfasdf --generate-to 1QATWksNFGeUJCWBrN4g6hGM178Lovm7Wh --coinbase-sig "rig1: This is Joe's block!"

Yes thanks.
Works.
I think the most difficult part of programming is learning IDEs.... the language is always the easy part.
Note: select the 'mbw' project on the projects window before doing build->select build variant (on other projects is might show grayed out)
Do you know if there is any doc that explains the project/module structure ?

I still haven't set up an Android dev environment due to laziness and lack of time and resources... but looking at the github code, that gradle build is supposed to be able to create multiple APKs If you are using Android Studio, it would appear that to pick the "Product Flavor" that you want: You can change the build variant to whichever one you want to build and run—just go to Build > Select Build Variant and select a one from the drop-down menu. To start customizing each build variant with its own features and resources, however, you'll need to know how to create and manage source sets.
So, theoretically you should be able to pick "prodnet"... Given that is listed as a product flavour here: https://github.com/mycelium-com/wallet/blob/master/mbw/build.gradleThanks a million. Works.

Hi,
I git cloned the Mycelium wallet code, opened it in android studio and built it.
It built the test net version.
What do i need to change in the code to create the production wallet app ?
Do you have any building readme/ code architecture docs that are public ?
I want to try to add an import option for transaction labels...

Hi, I have an old wallet and transactions on a 32 bit bitcoin-qt client. I upgraded the client to version 11.0 , every time it loads it does a new rescan which takes a long time and at the end it crashes  All this is on a virtual box vm. I have on my host another bitcoin at version 11 but it is 64 bits. Will i be able to transfer all my profile files to the 64 bit version ? (wallet.dat, and the file the holds the transaction labels i had there are the most important) What i am actually asking is "are the data files the same format in 32bit and 64 bit" ? Thanks |

Hi luke, remember me ? way back... port 80 requester for pool  Anyway, i have a small question. I am sorry if this has been asked before (couldn't find an answer)... its hard to perform search only on this thread in this forum system... Currently mining eligius pool using BFL jalapeno and cgminer(3.8.4), on XP (  ). (I know BFG is recommended but couldn't manage to get it to recognize my BFL yet) my command line is simple: cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u <my addr> -p x When I turn on 'verbose', I see many "Share above target" messages. e.g., [2013-12-06 14:08:28] Share above target

What does this mean ? I read in general that it means that shares I submitted are not relevant... it that normal ? Does that depend on the difficulty given to my client on the pool ? Is it client side configurable ? Also see the "BAJ0: invalid nonce - HW error" from time to time, but i understand it's a known evil for ASICs which you have to accept ... true ? |

maybe I don't understand it correctly but when i mine solo using bitcoin-qt and launch the bitcoin client for solo mining from the bitcoin-qt client, i see blocks being solved (difficulty 1) and a 300-400 MH/sec rate, but when i launch the new debug console in the 0.7 client, and then run the
I get the following:
22:57:19

getmininginfo
22:57:19

{
"blocks" : 199885,
"currentblocksize" : 75095,
"currentblocktx" : 169,
"difficulty" : 2864140.50781097,
"errors" : "",
"generate" : false,
"genproclimit" : -1,
"hashespersec" : 0,
"pooledtx" : 183,
"testnet" : false
}
shouldn't it show the hash rate as 300-400 too ?
or am i mixing the commands up and there is a different command for showing this info ?

People ARE donating with Bitcoins. This is their public donation address: http://blockexplorer.com/address/1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36vAs you can see, there have been a good amount of transactions after they announced that they're under a financial blockade. And that's only the public address, some people have most likely donated to a unique address. from the wikileaks donation page bitcoin section: For maximum security and anonymity, you can request a one-time Bitcoin address. To do so, please join our IRC and type /msg Bitcoin new. Our helpful bot will generate a new donation address for each transaction. Please make sure Bot is active on #bitcoin channel and has @ to the left of his nick.I assume most donations used that channel |

Hi Sgravina,
I saw your previous card was a sapphire 5870 - exactly the same card I had.
Did you have any problems with it ?
I am running almost 2 months and keeps freezing and hanging my system (win 7 64bit, corei3-2100,gigabyte P67A-UD3-B3 MB, no OC on GPU or CPU).
The GPU heats up quite a lot and i think it causes the mobo to freeze up the system.
I saw you are using an expensive asus mobo (ASUS P8P67 Pro), did you ever try using different mobos with the card ? maybe gigabyte ?
do you think my hunch is correct and the problem is that i am using mobos that are too sensitive to heat over time ?
This is the second gigabyte mobo i tried an both caused me system hangs every 24-72 hours.

i upgraded to the latest version from a few back (may) and use opencl miner. now my hashrate is much faster ! im getting 20mhs more. thanks. donation made.
same here ... on 5870 went from 369MH to 389MH just by upgrading guiminer package ! Thanks. Sent donation too. here's a tip - i saw that if i mine on CPU too i get more on the GPU ... a few more MH/s strange but cool... |

I used to have a case with 2xIN 2xOUT (all were 80cm) - didn't work.
Now i have 1xIN 1xOUT (all 120cm) + open the side panel and put a big house fan at max speed blowing in air - doesn't work.
I think the MB is not designed to work at high temp (even though my mb is at ~42-44C).

mastergamer: what is the board model ? (even though i am looking for a s1156 board, i would like to see if your board has the MB heatsink right under the GPU like most boards do)
|
|
|
|
|
thanks, but i am kinda looking for intel MB. anyone else usign 5870 with intel cpu out there ?
|
|
|
|
|
yeah... as i said - it aint the GPU its the MB i am sure !
The situation described is exactly what i experienced.
Now the MB is dead and I am looking for a new one.... any one out there with a sapphire 5870 and can recommend a good MB ?
