1 2010-11-17 00:01:27 <johnyh> who is using Diablos miner? is it good?
  2 2010-11-17 00:08:21 <davex__> What does the number in my "3/unconfirmed" status string represent?
  3 2010-11-17 00:11:14 <brocktice> johnyh: I've tried it, didn't work well on my 5970s.
  4 2010-11-17 00:11:25 <brocktice> But according to him it's because my system is wack
  5 2010-11-17 00:11:44 <brocktice> davex__: That means three confirmations have been done, I think?
  6 2010-11-17 00:11:52 <brocktice> It's not considered confirmed until it hits six?
  7 2010-11-17 00:12:04 <AAA_awright> What block number are we on?
  8 2010-11-17 00:12:22 <davex__> ok
  9 2010-11-17 00:12:27 <brocktice> 92279 is next I think
 10 2010-11-17 00:12:39 <AAA_awright> Kiba: idk, maybe boots of speed or something, grab a list from IdleRPG
 11 2010-11-17 00:17:59 <AAA_awright> ~blocks
 12 2010-11-17 00:18:06 <AAA_awright> What's the command?
 13 2010-11-17 00:18:10 <XxMalouinxX> ;estimate
 14 2010-11-17 00:18:14 <theymos> ;;bc,blocks
 15 2010-11-17 00:18:16 <gribble> 92281
 16 2010-11-17 00:18:44 <AAA_awright> Hmm, there has to be a better way to do this than downloading ten-thousand blocks at a time
 17 2010-11-17 00:19:18 <AAA_awright> Has anyone submitted the EFF donation announcement to slashdot yet?
 18 2010-11-17 00:21:22 <tcatm> which announcement?
 19 2010-11-17 00:22:46 <AAA_awright> EFF seems to be accepting Bitcoin donations
 20 2010-11-17 00:22:55 <AAA_awright> I wonder what they are planning to do with it
 21 2010-11-17 00:22:59 <AAA_awright> Sell it?
 22 2010-11-17 00:23:01 <tcatm> yes but they didn't announce it
 23 2010-11-17 00:23:18 <AAA_awright> Someone did
 24 2010-11-17 00:23:22 <AAA_awright> I wonder why they didn't
 25 2010-11-17 00:25:27 <theymos> So apparently transaction and block hashes can be identical to one another without breaking SHA-256. I wonder if Bitcoin is able to handle these edge cases properly.
 26 2010-11-17 00:27:15 <tcatm> maybe you can ask on the forum so satoshi might answer
 27 2010-11-17 00:28:39 <AAA_awright> I appear to be generating even though I only have 80546 blocks... any idea what's going on?
 28 2010-11-17 00:28:50 <AAA_awright> 254k hash/s
 29 2010-11-17 00:28:56 <theymos> I think it'd just ignore identical blocks, even if such blocks could be valid next blocks.
 30 2010-11-17 00:29:28 <brocktice> Is nobody else seeing a memory leak in bitcoind?
 31 2010-11-17 00:29:43 <brocktice> valgrind isn't showing anything yet, I guess it woulld.
 32 2010-11-17 00:29:45 <brocktice> *would
 33 2010-11-17 00:29:55 <brocktice> but should bitcoin be reading or exceeding 1GB of RAM over time?
 34 2010-11-17 00:30:07 <brocktice> reaching, damn my fingers
 35 2010-11-17 00:30:24 <tcatm> my bitcoind has been running for over a month without leaking
 36 2010-11-17 00:30:36 <brocktice> tcatm: do you use getwork?
 37 2010-11-17 00:30:40 <brocktice> also which version?
 38 2010-11-17 00:30:40 <tcatm> no
 39 2010-11-17 00:30:54 <tcatm> it's based on 311
 40 2010-11-17 00:31:10 <brocktice> hm, ok
 41 2010-11-17 00:31:11 <tcatm> wrote my own tcp work dispatcher
 42 2010-11-17 00:32:24 <doublec> brocktice, I notice memory increasing too
 43 2010-11-17 00:32:47 <doublec> brocktice, I periodically restart it
 44 2010-11-17 00:34:32 <brocktice> doublec: Yeah I now have a cron job on my miner resetting it
 45 2010-11-17 00:34:41 <brocktice> doublec: are you using a patched client or normal?
 46 2010-11-17 00:35:11 <doublec> brocktice, the normal client
 47 2010-11-17 00:35:28 <brocktice> doublec: hm, so it's not the getwork patch then. bitcoind or the graphical client? Which version?
 48 2010-11-17 00:36:10 <doublec> brocktice, bitcoind. I've noticed it since about 0.3.13
 49 2010-11-17 00:36:22 <brocktice> OK, thanks
 50 2010-11-17 00:37:20 <brocktice> oh, valgrind did find leaks
 51 2010-11-17 00:37:53 <doublec> nice
 52 2010-11-17 01:05:31 <johnyh> brocktice: bugs in what, the bitcoind ?
 53 2010-11-17 01:07:13 <brocktice> johnyh: actually in the GUI client
 54 2010-11-17 01:07:20 <brocktice> it has issues with bitcoind because it forks or something
 55 2010-11-17 01:07:23 <brocktice> I'm not valgrind expert
 56 2010-11-17 01:07:39 <brocktice> Vodka does bad things to my typing, sorry.
 57 2010-11-17 01:08:05 <brocktice> But, on my miner bitcoin slowly uses memory over time, so that I have to reset it.
 58 2010-11-17 01:08:41 <brocktice> I tried running it in valgrind for a few minutes and it did find some leakage. doublec was saying he'd noticed it in bitcoind since 0.3.13
 59 2010-11-17 01:09:44 <ArtForz> yeah, there seems to be something wrong
 60 2010-11-17 01:10:09 <brocktice> ArtForz: do you restart it periodically or what?
 61 2010-11-17 01:10:13 <brocktice> That seems to be what works for me.
 62 2010-11-17 01:10:15 <ArtForz> yeah
 63 2010-11-17 01:10:20 <brocktice> feels dirty though
 64 2010-11-17 01:10:24 <ArtForz> I did some TX spamming on TEST net, bitcoind consumed 2.3GB ...
 65 2010-11-17 01:10:46 <brocktice> heh
 66 2010-11-17 01:10:48 <ArtForz> and nothing THAT crazy, just a few 1000 TX
 67 2010-11-17 01:10:56 <brocktice> that reminds me, I'd better get that swapfile working on my miner
 68 2010-11-17 01:11:32 <ArtForz> so.. yeah, I think we have a leak somewhere
 69 2010-11-17 01:11:59 <ArtForz> my guess is old cached transactions keep hanging around in memory
 70 2010-11-17 01:14:06 <brocktice> So, I predict we'll see a pretty big dropoff in new miners.
 71 2010-11-17 01:14:15 <brocktice> I looked into buying some more hardware.
 72 2010-11-17 01:14:21 <brocktice> The payoff times are getting quite long.
 73 2010-11-17 01:14:30 <brocktice> (with upcoming difficulty of 6500 or so)
 74 2010-11-17 01:14:41 <ArtForz> yep
 75 2010-11-17 01:14:58 <brocktice> Thought I'd wedge in another 5970 and a few more 5770s
 76 2010-11-17 01:15:11 <ArtForz> and I'm guessing more towards 6800ish
 77 2010-11-17 01:15:11 <brocktice> But I don't currently think it's worth it. If prices go up for bitcoins that could change.
 78 2010-11-17 01:16:07 <brocktice> So, I wonder what will happen, guess we'll see.
 79 2010-11-17 01:16:32 <ArtForz> unless price skyrockets I'm prolly gonna add 2 more boxes @ 4 5970 and thats it
 80 2010-11-17 01:17:00 <brocktice> You said stock 5770s are around 180 Mhash/s right?
 81 2010-11-17 01:17:04 <ArtForz> sec
 82 2010-11-17 01:17:16 <ArtForz> no, 156ish
 83 2010-11-17 01:17:21 <brocktice> ouch
 84 2010-11-17 01:17:28 <ArtForz> OCed to 1000 they're 180ish
 85 2010-11-17 01:17:33 <brocktice> oh maybe that was the OC'ed value
 86 2010-11-17 01:17:45 <ArtForz> errr... no, at 960 they're 180ish
 87 2010-11-17 01:18:12 <ArtForz> at 1000 core ~ 188Mh/s using my miner
 88 2010-11-17 01:18:28 <brocktice> Yeah that'd be 21 days to pay off at diff 6800
 89 2010-11-17 01:18:36 <brocktice> give or take
 90 2010-11-17 01:18:47 <brocktice> at $0.2/btc
 91 2010-11-17 01:19:04 <ArtForz> and of course diff seems to x1.5 every ~10 days
 92 2010-11-17 01:19:30 <brocktice> Like I said, I think the slope will probably decrease soon.
 93 2010-11-17 01:19:46 <ArtForz> my guess is, somewhere in the 7k-10k region
 94 2010-11-17 01:19:50 <brocktice> unless price rises
 95 2010-11-17 01:19:55 <ArtForz> yep
 96 2010-11-17 01:20:24 <ArtForz> around there nv mining becomes unprofitable for people paying "normal" power prices
 97 2010-11-17 01:22:34 <theymos> ArtForz: Were you the one who made those two transactions with identical hashes (d5d27987d2 in 91812 and 91842)?
 98 2010-11-17 01:23:18 <ArtForz> nope
 99 2010-11-17 01:23:39 <theymos> Do you know what Bitcoin does when someone spends them?
100 2010-11-17 01:23:53 <ArtForz> good question
101 2010-11-17 01:24:06 <ArtForz> I *think* one of em gets ignored
102 2010-11-17 01:24:23 <theymos> That's my thinking, too.
103 2010-11-17 01:24:31 <brocktice> It's kind of nice that my office doesn't get too cold
104 2010-11-17 01:25:11 <ArtForz> it's WAY too warm for november here
105 2010-11-17 01:25:21 <ArtForz> thats why I'm only running 8/12 5970s
106 2010-11-17 01:26:06 <brocktice> ArtForz: which part of .de?
107 2010-11-17 01:26:32 <ArtForz> bavaria
108 2010-11-17 01:26:52 <brocktice> almost identical to here (Minnesota, US)
109 2010-11-17 01:27:11 <brocktice> ArtForz: Ever heard of a place called Joedlerwirt in Munich?
110 2010-11-17 01:28:12 <ArtForz> nope
111 2010-11-17 01:28:34 <brocktice> Oh, it's a lot of fun, might check it out if you're there looking for a good place to drink and listen to yodeling.
112 2010-11-17 01:29:03 <brocktice> Right off Marienplatz
113 2010-11-17 01:29:55 <brocktice> anyway, I'm out, g'night all
114 2010-11-17 01:40:48 <AAA_awright> How do two identical hashes form?
115 2010-11-17 01:40:58 <AAA_awright> Did we crack SHA1?
116 2010-11-17 01:41:10 <ArtForz> it's 2 identical coinbase TX
117 2010-11-17 01:41:23 <theymos> They reuse their key, and happen to get the same ExtraNonce.
118 2010-11-17 01:41:37 <AAA_awright> It doesn't contain the previous block hash/
119 2010-11-17 01:41:40 <AAA_awright> ?
120 2010-11-17 01:41:47 <theymos> Transactions don't.
121 2010-11-17 01:41:57 <ArtForz> coinbase? no
122 2010-11-17 01:42:15 <AAA_awright> Oh, transactions... hmm
123 2010-11-17 01:42:52 <AAA_awright> Yeah back to my comment, we need a million-bitcoin prize for someone who can prove or disprove the possibility that we can keep all the same functionality without a transaction log
124 2010-11-17 01:43:42 <theymos> It's impossible to prove that something doesn't exist (ie no double-spends) without having a complete log of all unspent transaction.
125 2010-11-17 01:43:51 <AAA_awright> Has that been proven?
126 2010-11-17 01:44:08 <AAA_awright> Either make it impossible or mathematically hard
