641  Bitcoin / Development & Technical Discussion / Re: Bitcoin 0.9.0rc2 is available for testing [Changelog] on: March 08, 2014, 07:28:56 PM
ETA on 0.9 Stable? Only interested because I'm running an altcoin that I want to upgrade the code of and want to get the best base code possible.

i've been running this on a handful of noglegs for 4 days w/o any issues

i'll take credit for the 15% faster transaction propagation times..  hoho
642  Bitcoin / Pools / Re: P2Pool.com support and information thread on: March 08, 2014, 07:06:29 PM
The decentralized nature ensures that blocks found are distributed to many nodes quickly, even if the node that finds the block has a slow upstream connection which helps to have fewer orphans.  This means it is seen more quickly by more nodes.  I saw the stats on it a few months ago somewhere and p2pool had very few orphans.  This seems to be what you said near the end of the paragraph - often the large network effect is more beneficial than a single large pipe is.  Obviously it is not 100%.

I'd actually be curious to know what p2pool's bitcoin orphan rate is for the last 6 mo vs other pools...

... but I still think it'd be more accurate to call this a benefit of how the p2pool protocol works, rather than attributing it to decentralization.  A pool could do something similar, by only connecting to a handful of nodes that they know to be well connected & have 1Gbps+ connections..

Cloud mining on PBMining has worked well for me
- 0.0089BTC/GHs. price adjusted at difficulty changes
- Weekly payouts
- Good customer service
- Refferal program

5 Year Mining Contracts at PBMining: 0.0089 BTC/GHs!

Uh, maybe if that 0.0089BTC per GH (!) is for two years?...   in one year you should expect to net about $5 from it.

ed:  Oh, I see... it's 5 years.  OK, then it's about break even... you'd earn next to nothing in years 2-5, but it should be enough to cover the initial cost...

well, not really, because of inflation and better investment opportunities

not to mention the huge leap involved in assuming this place will be around for 5 years

ed2:  if it was more profitable to use it then to sell it to chumps, that's what they would do.  just sayin.

my box is currently in the living in a case while i test it so temps are a little high.

i undervolted the bios to 1.1v and i use the setting below.

"xintensity" : "4",

"monitor" : "cat >> /home/cgminer.log",
"kernel" : "alexkarnew",

credit goes to http://www.reddit.com/r/litecoinmining/comments/1wc5th/bounty_undervolting_gigabyte_r9_270_bios/cf0y97g for the idea.. i just weaked it a litle for my own use.

these settings are great.  doesn't strain the card & I can't run at 1500 mem w/o it crashing every once in a while anyway.

I changed it to 1080-1200 and they are running at 475khash

(and even if I could run it at 1120-1500 or whatever, the power savings from being able to drop voltage a bit is probably worth it)

646  Economy / Services / Re: who (in the U.S) wants to build this miner for me.... on: March 07, 2014, 10:41:19 PM
Ok - so I've been doing a lot fo reading about mining equipment and I own a Bitmain S1 Dual Blade but now I'm ready to move up.

I've read here that someone else built the following and he (or she..not sure) believe it will run over 2 GH/S so I'm soliciting opinions and would like someone to build it for me. I'm sure I'm capabale since I was swapping boards back in the early 90's when the only NIC was arcnet but I have NOT had my hands 'seriously' in hardware for 20 years although I was swapping boards in some office PC's yesterday but it's nothing like building one of these rigs.

I'll pay to have it built - order what you tell me to have it all sent you your place - have you build and test it then ship it to me. If it goes well I may come back to you for additional computers. You SHOULD have lot of posts here and a great reputation. We'll need to talk on the phone and you MUST be in Canada or the U.S.

If you're in the Northeast, U.S. or Mid Atlantic area that's even between I live near Newark, De.

here's what I'd like to have built.

water cool the quad 7970's

AMD FX-8120
Asus M5A97 r2.0
Gigabyte ATI 6990 (x2)
Wifi card
128GB SSD
Coolermaster 1200w 80gold
Diskdrive (for driver CD's)
Corsair 600T


thoughts, opinions, takers?

thanks in advance...

that ^^ above will get you about 1.8ghash, which would be less than 1/1000th of 2 thash

but i don't see any quad 7970s, just two 6990's

buying stuff to mine bitcoins is a losing proposition

start developing your own ASICs instead

2. Mined coins and rewards are paid instantly, so they are not held by a pool operator - so  you can't be goxed.
They're rewarded instantly but you have to wait for them to be confirmed to be 'paid'.

agree, re: 2nd part.  no clue why people use all these mpos pools run by shady figure x
Quote
5. p2pool is DDoS resistant.
sort of.  the network as a whole is 99.99% DDoS resistant, an individual node is not.
Quote
6. p2pool fees are generally significantly less than other pools
sort of.  for some reason lots of people like to mine on p2pool.org and it charges 2%.  but, then, it seems like people congregate towards the pools that charge the highest fees anyway.  guess that's why eclipsemc and bitminter have never become especially popular
Quote
8. p2pool generally has fewer orphan bitcoin (and *coin) blocks due to its decentralized nature
this isn't correct, it's not the decentralized nature that would lead to fewer orphans, that'd actually cause more orphans, since most (if not all) major pools have relay nodes with significant bandwidth.  user X with 256kbps upstream, would cause plenty of orphans.  I haven't looked at the actual stats, but I'm pretty sure the less orphan part is true, but that's because the block is relayed to all other p2pool users, which requires significantly less bandwidth (then in theory one of those p2pool users will have good connectivity, when I ran my p2pool node the person that showed on blockchain.info 90% of the time was either a node in russia, france, or my node in germany).
Quote
Notes:
• Don't forget to set a backup pool
yeah, probably should have two backups.  oh, feel free to use nogleg.net:9555 for DOGE, hoho
Quote
• It is normal to have higher rejection rates on p2pool since it generates work faster than other pools and does not impact earnings.
the first part is correct, since the share time (should) be less than the block time for various coins.  the second part doesnt necessarily hold true though.  an easy example is p2pool.org, where you get lots of DOA shares, which arent caused by your own latency.
Quote
• p2pool payouts ramp up over time, 3-7 days is normal depending on the coin.
i'd say more like 12-24hrs
648  Economy / Service Discussion / Re: Cloud mining on: March 07, 2014, 10:18:59 PM
How to know if a cloud mining is profitable?
It is always profitable for the cloud and almost never for the miner. Genius business model; dunno why people keep throwing their money at it but I guess they repeatedly count on people not understanding diff and mining - and it seems to work every time.
'almost never'...   I guess the time when it's profitable for the user would be when they 'resell' that bandwidth?  I believe you can do that on at least one of these places that charges the nosebleed prices

Regarding http://bitcoin.advmapper.com:9332/static/

1: How can I tell if people are using my P2Pool node?
2: If I don't mine, is there any reason to host a P2Pool node?
3: My GetBlockTemplate latency is rarely/barely under 1 sec, even with just P2Pool and Bitcoind running. Why? CPU usage is almost nothing, disks are SSDs and there appears to be no swapping happening.
4: How do people find a P2Pool node to use, and what kinds of things helps them make the decision about which is best for them?
5: Is the P2Pool network hurting for nodes, or is there a surplus of nodes and it's just miners that are missing?

4) orphan rate and whether DOA is excessive vis-a-vis probable latencies.  i used to mine at 200ms pool.  with 15s share times, i'd get around 2.5-3% DOA

example: p2pool.org latency isn't that bad, yet DOA far exceeds mathematical probability

markets.cx/affiliates/promote/?u=5317ea9605af48cc3c8b5685 - new scrypt cloudmining

Site friendly as cex.io (fast buy and sell)

scrypt.cc - 1000 dollars per 1000khs
markets - 600 dollars per 1000khs

PC with 4 r9 280x (3000khs) - 2500 dollars or smth

I bought a couple of 260x's, & some 270's several months ago...... the 260x's came with the 2 free games (Thief + x), the 270's came with a $20 MRI (which I didnt use, but would have brought the cost down to $160).... the 260x after selling games (right at this moment Thief + Dirt 3 would be the best choices) would be around $100

so, my equipment has appreciated in value.  I can sell it used for more than I paid retail

these 'cloud mining' places are all massive ripoffs
656  Bitcoin / Mining / Re: Be honest, do you miss CPU/GPU mining days? on: March 06, 2014, 10:44:30 AM
I do miss the days when my Radeon HD6950 can make me a lot of money mining in 2011 and the really low difficulty compared to now.If BTC does lose a lot of value (seems to have a boom-bust cycle) the difficulty will simply have to drop meaning that I can start mining BTC more easily again (except now my HD6950 and my Ant miner/DualMiner combo will hash a lot more when put together) until difficulty skyrockets again.

It was a lot simpler software wise as I didn't have to contend with all the ASIC setup stuff that's more complex on PC/Mac as you have to go to the trouble of installing drivers and a lot more complex stuff vs simply installing catalyst (Open CL needs to be there for a GPU to mine) and running GUIMiner on my PC and I off I go.

I think that the difficulty's far too high,things are too complex setup wise now (since there's no standardization with 1 driver/software to use with the ASICs like there was with a GPU setup,catalyst and GUIMiner was all I needed to mine) and there are too many alt-coins that can't be all mined the same way which I find confusing (Sha-256,Scrypt,Scrypt-Jane,Scrypt-Adaptive N,Blakecoin,etc) and frustrating.

Smiley

Hmm, are setting up ASICs really that difficult?  I've always been under the impression that it was much more difficult to set up an efficient & effective GPU farm rather than just buying some $5000 ASIC
657  Alternate cryptocurrencies / Mining (Altcoins) / Re: 5x280x Rig | 1750w will cut it? on: March 06, 2014, 09:42:11 AM
hello guys.

planning on buying 5x gigabyte 280x's and getting them together with Asrock h81 PRO BTC.
along with them:

1xCoolermaster V1000 1000W - MB+CPU+3x280x
1xCorsair CX750 750W - 2x280x

do you think its enough? the thing is is heard that no matters who powers the gpu the gpu will take about 50w from the PSU connected to the board. is this a problem?

thank you

well, you dont even tell us if they're bronze/silver/gold/plat cert.  i guess i could look up the models but i'm way too lazy.

i used to run three 5970's on a 750 watt gold cert seasonic in 100oF ambient

most of the gold cert psus will be about to put out 5-15% more than the watts shown, it'd just be horribly inefficient energy wise.  most of the non-cert, 100oF and running at 75% load = dead psu

and some just use better components, eg my two 850w thermaltake toughpowers that i've had for 6 years
658  Alternate cryptocurrencies / Mining (Altcoins) / Re: P2Pool Detailed Settings for Altcoins on: March 06, 2014, 09:25:41 AM
What is MAX_TARGET?  I've noticed it's different for various coins but not sure how it's computed.

the maximum custom difficulty you can set

hmm, nm, i'm not 100% sure about that actually, would have to look at the source again.   i think that's what it is, though.

btw, for any coin with, say, block times of 2 or 3 minutes or less, you should remove the following in data.py:

if best is not None:
            best_share = self.items[best]
            punish, punish_reason = best_share.should_punish_reason(previous_block, bits, self, known_txs)
            if punish > 0:
                print 'Punishing share for %r! Jumping from %s to %s!' % (punish_reason, format_hash(best), format_hash(best_share.previous_hash))
                best = best_share.previous_hash

...  first off, these blocks are too fast to have that anyway.  not to mention that the vast majority of the time this will be beneficial to your node.  if you build off of that old valid *share that's just getting punished because of a new block, all the other clients will follow your chain (as it'll be the longest).  this way you don't end up making a share some 3 seconds later and have some slow (or modified, heh heh) node build off the original share
