22 2013-02-04 00:48:16 <HM2> what :S
23 2013-02-04 00:49:02 <Aranjedeath> libboost1.48-all-dev pulls in 271mb of packages
24 2013-02-04 00:49:13 <HM2> yeah
25 2013-02-04 00:49:18 paraipan has joined
26 2013-02-04 00:49:25 <HM2> if you're building bitcoind you'll need the huge dev package
27 2013-02-04 00:49:30 <Aranjedeath> damn
28 2013-02-04 00:49:34 <HM2> the boost-libraries themselves are <10MiB though
29 2013-02-04 00:51:49 <HM2> bitcoind makes quite a lot of use of boost
30 2013-02-04 00:52:19 <Aranjedeath> yeah

38 2013-02-04 00:54:56 <Aranjedeath> yeah
39 2013-02-04 00:55:07 <HM2> i had no idea it used asio
40 2013-02-04 00:55:18 <Aranjedeath> hmm
41 2013-02-04 00:55:26 <Aranjedeath> so why does db_cxx.h not exist
42 2013-02-04 00:55:33 * Aranjedeath grumbles
43 2013-02-04 00:55:38 <HM2> hold on
44 2013-02-04 00:56:09 <HM2> that's part of the berkley db package on my system
45 2013-02-04 00:56:38 <Aranjedeath> I pulled in... libdb4.8
46 2013-02-04 00:56:41 <Aranjedeath> and the dev package
47 2013-02-04 00:56:46 <Aranjedeath> does that cover me?
48 2013-02-04 00:56:48 <HM2> it's possible freebsd packages the c++ headers in a separate package
49 2013-02-04 00:56:49 <Luke-Jr> Aranjedeath: make ⦠BDB_INCLUDE_PATH=/usr/include/db4.8
50 2013-02-04 00:56:59 <Luke-Jr> after installing the ++ pkg
51 2013-02-04 00:57:05 <Aranjedeath> ++ package?
52 2013-02-04 00:57:12 <Aranjedeath> they don't have ++'s in my repo
53 2013-02-04 00:59:34 <D34TH> Aranjedeath: what distro
54 2013-02-04 00:59:47 <Aranjedeath> ubuntu
55 2013-02-04 00:59:50 <Aranjedeath> 12.04
56 2013-02-04 01:00:01 <Aranjedeath> precise iirc
57 2013-02-04 01:00:29 <Aranjedeath> huh, I had debs lying around from the last time I tried this
58 2013-02-04 01:00:38 <Aranjedeath> why isn't it noted in the docs that you can't get them from the repo
59 2013-02-04 01:01:21 <Aranjedeath> or is there a mysterious wiki page I should be reading :D
60 2013-02-04 01:04:07 <D34TH> 64bit or 32
61 2013-02-04 01:05:00 <Aranjedeath> 64bit
62 2013-02-04 01:05:28 <Aranjedeath> I've got a set of really ugly-named debs that have libdb4.8++ and -dev
63 2013-02-04 01:05:42 <Aranjedeath> seems to have fixed my issue
64 2013-02-04 01:05:46 <D34TH> oh
65 2013-02-04 01:06:02 <Aranjedeath> hence `huh, I had debs lying around from the last time I tried this`
66 2013-02-04 01:06:14 rdymac has joined
67 2013-02-04 01:06:19 <Aranjedeath> but the fact that you need libdb4.8++ is not noted in the makefile docs
68 2013-02-04 01:06:47 <Aranjedeath> vs libdb4.8, which will come up in apt-cache search (even with the ++ on the name) and doesn't have what you need
69 2013-02-04 01:06:48 <Aranjedeath> :P

72 2013-02-04 01:08:30 <Aranjedeath> yep, but it breaks compatibility
73 2013-02-04 01:08:38 <Aranjedeath> thaaats not cool :P
74 2013-02-04 01:09:22 <D34TH> breaks compat with releases
75 2013-02-04 01:09:32 <D34TH> just stay with master
76 2013-02-04 01:09:34 <D34TH> :D
77 2013-02-04 01:09:51 <Aranjedeath> lmao yeah
78 2013-02-04 01:10:00 <Aranjedeath> I'm just trying to get a big one up and running :>
79 2013-02-04 01:10:09 <Aranjedeath> I did it earlier but my node had to be taken down cause the box moved
80 2013-02-04 01:10:26 <Aranjedeath> I had sustained over 145 connections
81 2013-02-04 01:11:17 <Luke-Jr> Aranjedeath: why are you trying to compile at all? :P
82 2013-02-04 01:12:14 <Luke-Jr> D34TH: breaks compat with 0.8 release too
83 2013-02-04 01:12:24 <Aranjedeath> my blockchain is 080

91 2013-02-04 01:28:51 <Aranjedeath> listaccounts didn't provide anything useful
92 2013-02-04 01:29:17 <Aranjedeath> maybe I have to generate an address?
93 2013-02-04 01:37:17 <rdponticelli> Aranjedeath: getnewaddress to get a new
94 2013-02-04 01:38:21 <Aranjedeath> rdponticelli:) thanks :)
95 2013-02-04 01:38:21 <rdponticelli> getaddressesbyaccount to get the asigned to some account
96 2013-02-04 01:38:44 <Aranjedeath> listaccounts only gives me "" : 0.00000000
97 2013-02-04 01:39:12 <jgarzik> Luke-Jr: for which project is that commit?
98 2013-02-04 01:39:14 <rdponticelli> Yeah, that's the default account
99 2013-02-04 01:39:22 <Aranjedeath> okay, how do I get the address?
100 2013-02-04 01:39:24 <Luke-Jr> jgarzik: cpuminer

104 2013-02-04 01:40:05 <Aranjedeath> missed a letter or two :)
105 2013-02-04 01:40:07 <jgarzik> Luke-Jr: a two-line comment patch that is Via-CPU-specific?
106 2013-02-04 01:40:10 <Luke-Jr> yes
107 2013-02-04 01:40:13 <Aranjedeath> thank you very much
108 2013-02-04 01:40:14 <jgarzik> Luke-Jr: what about it?
109 2013-02-04 01:40:30 <rdponticelli> Just use getnewaddress

111 2013-02-04 01:40:34 <Luke-Jr> jgarzik: it confuses me, because bitcoind provided (getwork) the data in little endian, and it makes sense that it'd be converted to big endian for a dedicated processor like that
112 2013-02-04 01:40:40 <Luke-Jr> jgarzik: but the comment says the opposite
113 2013-02-04 01:40:41 Pasha has joined
114 2013-02-04 01:40:58 <Luke-Jr> jgarzik: and this commit also states the VIA converts it *back* to big endian (really little endian?)
115 2013-02-04 01:41:24 <HM2> go with middle endian
116 2013-02-04 01:41:28 <HM2> then everyone is miserable
117 2013-02-04 01:41:31 <jgarzik> Luke-Jr: VIA CPU docs for this are public
118 2013-02-04 01:41:35 <Luke-Jr> since it was added later, I'm wondering if there is some docs on the VIA which state how it handles the hashing internally?
119 2013-02-04 01:41:44 <Luke-Jr> oh, do you know where I can find it?
120 2013-02-04 01:41:54 <Luke-Jr> Google found some info, but nothing like proper docs :/
121 2013-02-04 01:42:02 <jgarzik> Luke-Jr: Don't recall the specific details, but it seemed like that was added in response to a comment or bug or somesuch
122 2013-02-04 01:42:27 <Luke-Jr> hmm, I'll check out the cpuminer github issues list - any other place that might have had it?

127 2013-02-04 02:10:15 <jgarzik> Luke-Jr: I think I got a bug report that got it going, but there were always lingering questions
128 2013-02-04 02:10:23 <jgarzik> would appreciate confirmation one way or the other
129 2013-02-04 02:11:48 <Luke-Jr> hmm, wonder if there's any cheap hardware with one of them
130 2013-02-04 02:12:03 <phantomcircuit> it's all cheap
131 2013-02-04 02:12:14 <Luke-Jr> phantomcircuit: ?
132 2013-02-04 02:13:17 <phantomcircuit> all the via hardware is cheap
133 2013-02-04 02:13:49 <Luke-Jr> I don't know of any ;)

138 2013-02-04 02:15:14 <phantomcircuit> they made very good home servers

168 2013-02-04 03:43:52 <weex> what if you make a backup of your wallet.dat and rename it? a new one should be created so at least you'll know if it was a problem with the wallet.dat file
169 2013-02-04 03:44:17 <Rlc23> thanks weex, definitely a wallet problem
170 2013-02-04 03:44:36 <Rlc23> i ran bitcointools wallet repair, got a much cmaller file, but it runs and appears to have all the keys
171 2013-02-04 03:45:05 <Rlc23> maybe a bad transaction right when bitcoind crashed?

429 2013-02-04 15:50:25 <kjj> hey Luke, did you notice that the bfg API commands are a jumble of <verb><noun> and <noun><verb> ?
430 2013-02-04 15:50:56 <Luke-Jr> kjj: I didn't. I try to avoid touching the RPC stuff >_<
431 2013-02-04 15:51:13 <kjj> hmm
432 2013-02-04 15:51:49 <kjj> most of the device commands are gpu/cpu/pga + verb, while most of the pool commands are verb + pool
433 2013-02-04 15:51:53 <Luke-Jr> that be troll territory lol
434 2013-02-04 15:52:17 <Luke-Jr> kjj: when/if I end up redoing parts of the RPC, I'll likely remove the GPU/CPU/PGA distinction altogether
435 2013-02-04 15:52:22 <Luke-Jr> it's useless and makes for headaches

442 2013-02-04 15:57:23 <Luke-Jr> kjj: Avalon is the only ASIC vendor who was unwilling to provide me with a device
443 2013-02-04 15:57:40 <Luke-Jr> although they did donate one to the Foundation, which in theory I'd expect I should be able to use for development
444 2013-02-04 15:58:17 <kjj> I'm hoping they can be converted to USB
445 2013-02-04 15:59:05 <Luke-Jr> I believe so
446 2013-02-04 15:59:18 <Luke-Jr> Jeff said it looks like serial, but his dmesg showed a serial-to-USB convertor
447 2013-02-04 16:00:19 <kjj> I didn't count the wires on the ribbon cables, but it looked too wide for serial to me
448 2013-02-04 16:01:34 <abracadabra> what cgminer version comes with avalon?
449 2013-02-04 16:01:47 <abracadabra> oh meh.. n/m found it
450 2013-02-04 16:04:54 <Luke-Jr> abracadabra: 2.10.4, but apparently modified a lot
451 2013-02-04 16:05:09 <Luke-Jr> abracadabra: the GBT seems to be more broken than normally
452 2013-02-04 16:05:13 <Guest55983> so asics are reality now, are they?

455 2013-02-04 16:09:03 <moore_> Luke-Jr, you wort the common patched to block SD right?
456 2013-02-04 16:10:02 <Guest55983> dedicated bitcoin asic miners
457 2013-02-04 16:10:15 <moore_> I have realized that my attack against SD can be leveraged in to a attack on bitpay
458 2013-02-04 16:11:17 <moore_> It can be used thou when ever there are differences in which TX are considered valid by miners
459 2013-02-04 16:12:16 <moore_> and Eliel pointed out that there are other asymmetries like accepting large blocks with small fees
460 2013-02-04 16:13:15 <Luke-Jr> moore_: I think you are wrong.
461 2013-02-04 16:13:18 <moore_> it is interesting because where it may not be considered a attack against bit coin it is a attack against common use ( if you considere bitpay common )
462 2013-02-04 16:13:21 <moore_> really?
463 2013-02-04 16:13:22 <moore_> why
464 2013-02-04 16:13:43 <Luke-Jr> moore_: I don't think you can hurt BitPay.
465 2013-02-04 16:14:04 <moore_> bitpay uses uncomited tx
466 2013-02-04 16:14:11 <Eliel> Luke-Jr: you can hurt some bitpay customers... but only those who have chosen to accept unconfirmed txs.
467 2013-02-04 16:14:29 <Luke-Jr> moore_: no, they don't.
468 2013-02-04 16:14:37 <Eliel> as far as I understand it, Bitpay will pass those losses to customers.
469 2013-02-04 16:14:40 <Luke-Jr> Eliel: sure, known unsafe practices are unsafe
470 2013-02-04 16:14:41 <Luke-Jr> that's obvious
471 2013-02-04 16:14:51 <moore_> Their demo videos show the use of uncomited tx
472 2013-02-04 16:14:56 <teenidle> hello
473 2013-02-04 16:15:32 <moore_> well bitpay's promo videos push it as safe
474 2013-02-04 16:16:01 <Luke-Jr> then email Tony

476 2013-02-04 16:16:10 <moore_> k
477 2013-02-04 16:16:41 <Luke-Jr> moore_: note the video looks like it's for retail like a restaurant
478 2013-02-04 16:16:47 <moore_> ya
479 2013-02-04 16:17:10 <Luke-Jr> moore_: so double spending in that case is like someone giving you a bad check
480 2013-02-04 16:17:13 <moore_> do you have a email for him
481 2013-02-04 16:17:22 <Luke-Jr> I'm sure it's on the site..
482 2013-02-04 16:17:28 <moore_> I just see info
483 2013-02-04 16:17:33 <Luke-Jr> that should work
484 2013-02-04 16:19:06 <moore_> Luke-Jr, if miners published there rules for tx accptance it would be much easer to avoid this attack

491 2013-02-04 16:24:32 <moore_> you mean that bitpay or who ever should have some deal with miners to make sure there tx get in?
492 2013-02-04 16:25:50 <amiller> i've read contradictory things about bitpay's policy, whether or not they wait 6 blocks before considering themselves contractually bound to pay out
493 2013-02-04 16:26:41 <moore_> what about in the chained case, where a customer spends a output of a unconfirmed tx that is not going to be accepted? I suppose most clinets don't let you spend unconfermed tx so you could just reject them
494 2013-02-04 16:26:45 <moore_> as valid
495 2013-02-04 16:27:47 <Luke-Jr> moore_: yes
496 2013-02-04 16:27:57 <jgarzik> amiller: Cannot speak for BitPay, but in general... it's product based

500 2013-02-04 16:28:16 <jgarzik> amiller: You can accept zero-conf, if the merchant can cancel a purchase before shipping a physical product

502 2013-02-04 16:28:36 <amiller> which suggests that bitpay would not actually pay out in case of a double spend
503 2013-02-04 16:28:48 <Luke-Jr> amiller: of course they wouldn't
504 2013-02-04 16:28:57 <jgarzik> ie. "payment accepted!" then the merchant checks before shipment, which happens hours or days later.
505 2013-02-04 16:29:36 <jgarzik> no idea if that's how BitPay does it, but it would make sense.

540 2013-02-04 16:57:50 <jgarzik> BTC Guild switched to pre-0.8, for at least a few of its machines
541 2013-02-04 16:57:59 <jgarzik> I wonder when we will lock in v2 blocks?
542 2013-02-04 16:58:14 <kinlo> jgarzik: it's still a long time before that happens
543 2013-02-04 16:58:33 <kinlo> we're barely at 50%
544 2013-02-04 16:58:55 <kinlo> blockorigin tracks the blocks, so you can easily see that several major pools still need to switch
545 2013-02-04 16:58:57 <Luke-Jr> jgarzik: despite the warnings that 0.8 shouldn't be used for mining yet? :P

547 2013-02-04 16:59:33 <Luke-Jr> jgarzik: as recently as 2 weeks ago, both slush's Stratum server and my Eloipool both made invalid v2 blocks in some cases :P
548 2013-02-04 16:59:41 <Luke-Jr> jgarzik: lack of testing only, I think

551 2013-02-04 17:00:28 <Luke-Jr> jgarzik: in slush's case, he wasn't encoding the height as a signed number; in my case, I was creating longpoll merkleroots with the height of the *current* block
552 2013-02-04 17:01:02 <Luke-Jr> jgarzik: do you have a clean blk0001 by any chance?

554 2013-02-04 17:03:39 <kinlo> does 0.7 enforce the rules for v2 blocks? ie will it reject v2 blocks without valid blocknum in the generation hash?
555 2013-02-04 17:04:00 <Luke-Jr> kinlo: after something like 98% adoption
556 2013-02-04 17:04:15 <Luke-Jr> IIRC 950 of past 1000 blocks
557 2013-02-04 17:04:22 <kinlo> it's 95% afaik
558 2013-02-04 17:04:27 <kinlo> so basicly, not yet
559 2013-02-04 17:04:45 <kinlo> it could have enforced the v2 rules already, and accept any v1 block
560 2013-02-04 17:04:52 da2ce7_d has joined
561 2013-02-04 17:04:54 <kjj> I thought that it enforced v2 rules on blocks claiming to be v2, but still accepted v1 blocks until the 95% mark hits
562 2013-02-04 17:04:57 <kinlo> but then again, one might exploit that
563 2013-02-04 17:04:58 <Luke-Jr> kinlo: not without risk of orphaning
564 2013-02-04 17:05:06 <Luke-Jr> kjj: yes and no
565 2013-02-04 17:05:06 <kinlo> indeed
566 2013-02-04 17:05:13 <kinlo> makes sense not to enforce the rules.

596 2013-02-04 17:18:56 <muhoo> TD: nobody in particular :-) i'm doing a bitcoin store in my spare time, using bitcoinj, to run the server on a cheap 500MB RAM VPS
597 2013-02-04 17:19:03 <TD> fees can be set explicitly, but solving them according to the protocol rules is unimplemented. i keep wanting to do it and then andreas convinces me it's not the biggest UX problem with the android wallet right now
598 2013-02-04 17:19:11 <TD> ah ok. i thought you might be somebody i talked to before
599 2013-02-04 17:19:56 <TD> muhoo: i'd strongly recommend to run a full node if you're actually selling stuff
600 2013-02-04 17:20:17 <TD> muhoo: but if you really can't afford that, make sure you at least are waiting for confirmations
601 2013-02-04 17:20:27 <muhoo> can't. not enough RAM. also, i need to be able to watch raw transactions. we're just selling music, no confirmations required
602 2013-02-04 17:20:58 <muhoo> nobody's going to want to wait a half hour to get their download.
603 2013-02-04 17:21:03 gjs278 has joined
604 2013-02-04 17:21:04 <TD> mmm. RAM is cheap though. i guess if you're on a strict budget the cost of running a node can be an issue.
605 2013-02-04 17:21:14 <TD> but i suppose if you get ripped off for some music it's no big deal
606 2013-02-04 17:21:22 <TD> ok, well, good to hear you find it useful at least
607 2013-02-04 17:21:22 <muhoo> that was the thinking.
608 2013-02-04 17:21:29 tsche has joined
609 2013-02-04 17:21:32 <TD> let me know if there's some features you want (beyond fees. i already know about them)
610 2013-02-04 17:22:00 <muhoo> the algorithm for fees in bitcoind looks pretty simple. probably wouldn't be that hard to just transliterate it to java
611 2013-02-04 17:22:06 <TD> btw do you use watching wallets at all? bitcoinj supports them but it's not really documented.
612 2013-02-04 17:22:20 <TD> sure. but it's also about making sure it's properly tested and things like that.
613 2013-02-04 17:22:28 <muhoo> PeerGroup.addWallet() ?
614 2013-02-04 17:22:28 <TD> it's not hard. it's just not floated to the top of the todo list yet, as i'm still quite mobile focused.
615 2013-02-04 17:22:45 <TD> muhoo: no, i mean, does your store have only public keys on it? you can keep the wallet with private keys on your own laptop or whatever
616 2013-02-04 17:22:53 <TD> it's more secure that way, a web server compromise can't steal the money collected
617 2013-02-04 17:23:24 <muhoo> the plan is to have one wallet per musician on the server, and as soon as payments come in, get them the hell off the server and send them to an address on file for the musician
618 2013-02-04 17:23:44 <muhoo> so that there are no coins sitting in live wallets on the server for very long
619 2013-02-04 17:23:50 <CodeShark> don't even have them come to the server in the first place
620 2013-02-04 17:24:06 <CodeShark> just watch for transactions - but don't hold any private keys on the server
621 2013-02-04 17:24:15 <muhoo> well, we want to take a cut. i guess could do that with raw transactions.
622 2013-02-04 17:24:25 <CodeShark> there's absolutely no good reason for keeping private keys on the web server
623 2013-02-04 17:25:28 <CodeShark> have musicians pregenerate a bunch of addresses and give you a list
624 2013-02-04 17:25:35 <muhoo> interesting. watch-only wallet makes sense.
625 2013-02-04 17:25:43 <muhoo> these guys aren't bitcoin savvy.
626 2013-02-04 17:25:55 <muhoo> i need to make it totallly stoned-ass-musician-proof
627 2013-02-04 17:26:31 <muhoo> these guys will take whatever they make and go spend it on silk road, no doubt :-)
628 2013-02-04 17:27:47 <eckey> ping Mike Hearn
629 2013-02-04 17:27:55 <TD> muhoo: hah. well, it's up to you. if you want to be automatically forwarding money direct from the web server then yeah it's an issue. if you have a second system that can be made more locked down than your web server (very likely) you can write a program that does the forwarding/cut taking for you
630 2013-02-04 17:28:21 <muhoo> TD: that is pretty much what i've got, yes.
631 2013-02-04 17:28:27 <HM2> if your web app can control your wallet then your wallet is only as secure as your web app
632 2013-02-04 17:29:15 <TD> eckey: pong
633 2013-02-04 17:29:50 <muhoo> HM2: true, but there are many wallets. "my" wallet is not on a web server. "a" wallet is, and it just forwards coins, essentially.
634 2013-02-04 17:30:24 <muhoo> but i'll look into other ways to do it, thanks for the suggestions all.
635 2013-02-04 17:30:52 <muhoo> heirarchal wallets BIP would make this a lot easier
636 2013-02-04 17:31:11 <CodeShark> indeed it would
637 2013-02-04 17:31:17 <CodeShark> I think I'm gonna just start implementing that3
638 2013-02-04 17:31:28 <CodeShark> no more waiting around for the cryptographers :p
639 2013-02-04 17:31:43 <HM2> heirarchical wallets?
640 2013-02-04 17:31:49 <CodeShark> BIP32
641 2013-02-04 17:32:02 <HM2> hi-er-arch-ic-al
642 2013-02-04 17:32:06 <HM2> i hate that word
643 2013-02-04 17:32:08 * muhoo can't spell, sorry
644 2013-02-04 17:32:16 <HM2> no i can't either :P
645 2013-02-04 17:32:43 <Luke-Jr> CodeShark: I'm pretty sure sipa is going to do that..
646 2013-02-04 17:33:12 <CodeShark> sipa is waiting on hal

649 2013-02-04 17:33:43 <CodeShark> sipa, that is
650 2013-02-04 17:33:56 <MC1984> i like how there are more new people talking about dev stuff
651 2013-02-04 17:34:03 <CodeShark> and I NEED a deterministc wallet
652 2013-02-04 17:34:03 <CodeShark> ASAP
653 2013-02-04 17:34:04 <CodeShark> like, yesterday
654 2013-02-04 17:34:06 <TD> muhoo: bear in mind that the current code doesn't handle multiple wallets very well. you can attach new wallets, but if you disconnect and reconnect them later, they won't automatically re-scan the right parts of the chain
655 2013-02-04 17:34:16 <TD> muhoo: so i'm not sure 1-wallet-per-artist is a good idea as they all need to be in RAM at once.
656 2013-02-04 17:34:32 <HM2> that BIP looks awesome
657 2013-02-04 17:34:43 <kjj> CodeShark: it is easy enough to make your own deterministic wallet
658 2013-02-04 17:34:44 <muhoo> TD: i noticed that, and was worried about it.
659 2013-02-04 17:34:45 <HM2> CodeShark: is the crypto side of it similar to key splitting used in vanitygen?
660 2013-02-04 17:34:46 <TD> muhoo: a design where you create a new key for each transaction in a single wallet and then record which artist it was for, seems to make more sense to me
661 2013-02-04 17:34:53 <CodeShark> kjj: that's exactly the idea
662 2013-02-04 17:34:54 <TD> muhoo: there's no real reason for every artist to have a wallet, imho.
663 2013-02-04 17:35:23 <kjj> but be sure to read up on how to do it right. if you do it poorly, you'll leak all of your private info
664 2013-02-04 17:35:54 <CodeShark> I don't set out to do things to do them poorly :)
665 2013-02-04 17:35:54 <muhoo> TD: good point. i can keep the mapping of addresses-to-artist in a database, which i was going to have to do anyway, to keep track of which songs were sold (so artists can see their sales history)
666 2013-02-04 17:35:55 <TD> yeah. the documentation for how to use bitcoinj in the merchant case isn't very good today. there was a guy (gary rowe) who wanted to do MultiBit Merchant and provide a merchant server to handle all this, but i never heard anything back
667 2013-02-04 17:36:16 <TD> muhoo: yeah. eventually you may run out of RAM anyway because the wallet keeps all spent transactions too, but there's no real reason for that. it can be fixed.
668 2013-02-04 17:36:35 <CodeShark> HM2, I haven't really used vanitygen much...but the same idea could be applied
669 2013-02-04 17:36:38 <TD> muhoo: just be aware that bitcoinj is designed for mobile phones/individual users and hasn't really been battle-tested for the merchant server case. you'll find things that need fixing.
670 2013-02-04 17:36:46 <muhoo> i noticed that too :-) a Wallet.toString() can get very long
671 2013-02-04 17:37:07 <TD> it can, yes. i'll probably fix that soon. there isn't a strong justification to keep spent transactions around except for historical interest.
672 2013-02-04 17:37:13 <CodeShark> we need a wallet that is merchant-facing...too much emphasis on mobile and end-user wallets...not enough on good, solid merchant solutions :)
673 2013-02-04 17:37:16 <muhoo> fair enough. i don't mind being on the bleeding edge here.
674 2013-02-04 17:37:19 <TD> cool
675 2013-02-04 17:37:23 <TD> might you contribute patches?
676 2013-02-04 17:37:29 <Luke-Jr> CodeShark: BitPay
677 2013-02-04 17:37:33 <CodeShark> bah
678 2013-02-04 17:37:36 <HM2> hmmm
679 2013-02-04 17:37:39 <muhoo> TD: i'd be happy to, if the opportunity arises
680 2013-02-04 17:37:43 <TD> superb
681 2013-02-04 17:38:08 <muhoo> IIRC there's a CA involved, i shoudl get up on that
682 2013-02-04 17:38:55 <TD> CA involved?
683 2013-02-04 17:39:51 <HM2> CodeShark: i'm looking at BIP32....it seems to me that child keys are just derived by salting and hashing parent keys?
684 2013-02-04 17:39:57 <muhoo> contributor agreement?
685 2013-02-04 17:40:04 <CodeShark> HM2: yes
686 2013-02-04 17:40:27 <HM2> How is that helpful?
687 2013-02-04 17:40:52 <muhoo> TD: if you require a signed agreement to accept patches, i should get that squared away at some point
688 2013-02-04 17:41:13 <TD> ah, yes, CLA. you can just sign it electronically.
689 2013-02-04 17:41:20 <TD> it's easy
690 2013-02-04 17:41:55 <CodeShark> you also multiply by some k, HM2
691 2013-02-04 17:42:35 <HM2> oh i see
692 2013-02-04 17:42:40 <eckey> TD: using bitcoinj, is there a way to specify a block or timestamp and have PeerGroup go back and catch up from that point? Would be useful when reconstructing a wallet.
693 2013-02-04 17:43:08 <eckey> rerun the transactions
694 2013-02-04 17:43:17 <HM2> K[n] i= I[L] * K[par]
695 2013-02-04 17:43:42 <HM2> so it is similar to the vanitygen keysplitting you told me about before, i believe
696 2013-02-04 17:43:54 petertodd has quit (Quit: Lost terminal)
697 2013-02-04 17:43:56 <HM2> just using a hash to produce a deterministic value
698 2013-02-04 17:44:22 <TD> eckey: wallet.clearTransactions(0); and then delete the block chain file.
699 2013-02-04 17:44:30 <TD> you can't currently do partial chain re-fetches
700 2013-02-04 17:44:39 <TD> it's not hard to implement. just didn't get to the top of the todo list yet.
701 2013-02-04 17:46:58 <HM2> hmm
702 2013-02-04 17:47:23 <muhoo> at least for testing purposes, it'd make life easier.
703 2013-02-04 17:47:23 <eckey> TD: and rerun from genesis?
704 2013-02-04 17:47:31 <TD> yes
705 2013-02-04 17:47:40 <TD> it'll use getheaders to catch up to the wallet birthday pretty fast though
706 2013-02-04 17:48:14 <HM2> CodeShark: I'm guessing I[L] in that math cannot be 1 or Kn = Kpar
707 2013-02-04 17:48:18 <muhoo> the new bloom filter code seems to speed it up dramatically
708 2013-02-04 17:48:33 <TD> are you guys on the bitcoinj mailing list?
709 2013-02-04 17:48:44 <eckey> pointer?
710 2013-02-04 17:48:50 <eckey> nevermind
711 2013-02-04 17:50:15 <TD> doing partial chain refetches for the single wallet case is pretty easy.
712 2013-02-04 17:50:43 <muhoo> this is a "hello world" running bitcoinj: http://spazcoin.bamfic.com
713 2013-02-04 17:51:00 <TD> doing it online when you have multiple wallets attached is a bit less easy, the current code more or less assumes it's at one "place" in the sync process. so some refactoring is required to be syncing/rewinding different wallets simultaneously. i suspect most apps don't need multiple wallets at once, so it's not high up my list.
714 2013-02-04 17:51:20 <TD> muhoo: oh, cool, that's a raw feed of every tx being broadcast?
715 2013-02-04 17:51:25 <muhoo> yep
716 2013-02-04 17:51:43 <TD> muhoo: bonus points for adding the transactions to an html list and updating the number of seen peers in place
717 2013-02-04 17:51:46 <TD> that'd be cool
718 2013-02-04 17:52:19 <muhoo> i'll need to do that in memory. once it's seen by 4 peers, i'll ship the download to the customer
719 2013-02-04 17:52:30 <muhoo> this was a test of that functionality
720 2013-02-04 17:52:41 <TD> sure

734 2013-02-04 17:57:41 <muhoo> ok, will do. you've already mentioned the main things i've already run up against: ram-bloat with wallet storing everything its seen, ability to replay the blockchain, etc
735 2013-02-04 17:58:17 <TD> yeah

739 2013-02-04 17:59:21 <muhoo> one of the things that's interestign to me as a store, is there's going to be some duplication of data between what's in the wallet and what i need to store in the db anyway (sales history)
740 2013-02-04 18:00:03 <TD> yeah. over time i want to find a good refactoring of the wallet so it can be saved to different kinds of database, rather than a file.
741 2013-02-04 18:00:16 <muhoo> right now i'm serializing it and saving it as a blob.
742 2013-02-04 18:00:23 <TD> i always wanted to let you attach data to arbitrary objects and have it be persisted during serialization.
743 2013-02-04 18:00:28 <TD> muhoo: protobuf serialization i hope!
744 2013-02-04 18:00:34 <muhoo> so one other thign would be nice is to have the auto-save code more general and not be tied to a File
745 2013-02-04 18:00:37 <TD> yeah
746 2013-02-04 18:00:38 <TD> i know
747 2013-02-04 18:00:52 <muhoo> yes, protobuf.

749 2013-02-04 18:01:01 <TD> for now though, i'm unfortunately still going to be focusing on mobile/desktop wallets, so these sorts of features won't happen unless somebody contributes them.

751 2013-02-04 18:01:20 <TD> on the grounds that if i try to satisfy every use case simultaneously it'll end up satisfying none of them well
752 2013-02-04 18:01:36 <muhoo> understandable.
753 2013-02-04 18:01:41 <CodeShark> merchant wallets should be an entirely different app than mobile wallets
754 2013-02-04 18:01:57 <CodeShark> they have two very different sets of requirements
755 2013-02-04 18:02:00 <muhoo> hmm.
756 2013-02-04 18:02:08 <TD> well, obviously they are different apps. it's about the features they demand of the underlying API.
757 2013-02-04 18:02:16 <gmaxwell> Luke-Jr: wrt the conversation in #bitcoin or wherever altcoins was coming up: https://en.bitcoin.it/wiki/User:Gmaxwell/alt_ideas
758 2013-02-04 18:03:02 <muhoo> if needed, i suppose there could be separate wallet classes with a common interface, etc.
759 2013-02-04 18:03:17 <muhoo> one for android wallets, one for merchant, etc,
760 2013-02-04 18:03:40 <TD> yeah, Wallet is a huge class though. the issue is really one of "save a consistent snapshot" vs "submit each change to a database layer in an easy SQLable form"
761 2013-02-04 18:04:03 <TD> the current code is only capable of the first. you can find out the wallet changed but there's no packaging up of the changes in a form that's good to put into an UPDATE statement.
762 2013-02-04 18:04:12 <muhoo> i wasn't going to try to break up the wallet into sql table fields or anythign crazy like that.
763 2013-02-04 18:04:29 nus- has joined
764 2013-02-04 18:04:40 <TD> well, i'm thinking about scalability. SatoshiDice had to make pretty big changes to allow the wallet to be in a database
765 2013-02-04 18:04:56 <TD> so now they're forked quite badly and fireduck seems uninterested in rebasing, so he isn't getting bugfixes and new features :(
766 2013-02-04 18:05:02 <muhoo> oh, do they? i didn't know their implementation.
767 2013-02-04 18:05:05 <TD> yeah

769 2013-02-04 18:05:12 <gmaxwell> Luke-Jr: you might find the 'chain folding' one there interesting, as I don't think I'd talked about that much in IRC. (Amiller may have had the same idea, but I wasn't completely clear on it until coming up with it myself. ... after doing so I realized he might have been saying the same thing)
770 2013-02-04 18:05:17 <TD> it's open source actually. but not mergable.
771 2013-02-04 18:05:25 <muhoo> :-(
772 2013-02-04 18:06:19 <Luke-Jr> gmaxwell: it would be neat to start a (general, not user-specific) wiki page listing different ideas and classifying them as no-fork, soft-fork, hard-fork, altcoin, etc
773 2013-02-04 18:07:25 <amiller> a half-formed ideas list maybe...
774 2013-02-04 18:07:43 <gmaxwell> Luke-Jr: yea, well I'm just throwing it on a userpage so I don't forget them (again). Feel free to mine it. What would be neat to do is to create a summary page for each idea, a short summary, a long argument with links to discussions about it and similar ideas.. then have a table that lists all of them and transcludes the summary pages for their summaries (<includonly>)
775 2013-02-04 18:08:13 <Luke-Jr> gmaxwell: sounds good ;)
776 2013-02-04 18:08:44 <muhoo> TD: in my case, i'm ok with doing my transaction tracking and sales tracking outside of the wallet
777 2013-02-04 18:09:15 <TD> ok

788 2013-02-04 18:16:59 <Pucilowski> anyway, I believe this is why they are taking unusually long to confirm, any ideas how I could re-broadcast it and have nodes relay it again?

847 2013-02-04 19:53:01 <kjj> I know I could have just pulled my pubkeys and recreate the addresses that way. I just wanted to see if I could fix addresses with a few missing letters on the end

849 2013-02-04 19:55:23 <kjj> brute force is plenty easy, and quick if you are only missing 1 or 2 letters. after that, it starts getting bad
850 2013-02-04 19:56:07 <HM2> potentially though there could be a collision
851 2013-02-04 19:56:09 <kjj> hmm. I wonder how much of my time is spent in bcmul()

858 2013-02-04 19:57:28 <kjj> very slim chance. the 32 bit checksum gives a 1 in 4 billion chance per try. that is less than 1% when replacing 4 letters, 15% at 5 letters (take too long to brute force anyway)
859 2013-02-04 19:58:01 <kjj> and at 6 letters, you'd get 8 false positives per correct address

865 2013-02-04 20:00:12 <kjj> my brute forcer is just a set of loops, each run through it tacks on a different combination of letters, then runs the new string through the decoder (which iterates bcmul) to reconstruct the pubkey and check

878 2013-02-04 20:08:25 <HM2> kjj, i think you can decode the address you have as a bigint and then multiply by 3364
879 2013-02-04 20:08:33 <HM2> then you only have to do an addition for each combination
880 2013-02-04 20:09:05 <kjj> base58 is placeless
881 2013-02-04 20:09:21 <gmaxwell> placeless?!@#!
882 2013-02-04 20:09:36 <kjj> as in AB means "A * B", not "A*58+B"
883 2013-02-04 20:09:58 <HM2> eh
884 2013-02-04 20:10:01 <HM2> how
885 2013-02-04 20:10:03 <moarrr> kjj? really?
886 2013-02-04 20:10:06 <gmaxwell> 0_o
887 2013-02-04 20:10:29 <kjj> no, shit. I might still be drunk
888 2013-02-04 20:10:43 <gmaxwell> Sounds like a likely hypothesis.
889 2013-02-04 20:10:53 <HM2> what i mean is if you pad with "00" then you only need to do one multiplication (x 3364) then you can just count up 3364
890 2013-02-04 20:11:04 <moarrr> yeh, what hes saying doesnt make sense if base58 is a binary representation of a number
891 2013-02-04 20:11:06 <HM2> I think?

895 2013-02-04 20:12:07 <jgarzik> Yes, believe it or not. I was in two minds as to whether or not this is a good idea or not, but for the dependencies I've used uint64_t instead of void * so that it is friendly with integer identifiers

904 2013-02-04 20:17:31 <kjj> I just need a new base58 decoder. mine returns a base256 binary, so I don't bother reconstructing the leading zeros and thus can't tell how many places I'm missing
905 2013-02-04 20:17:36 <pjorrit> kjj, those ints could be multiplied by A * B before casting to bool
906 2013-02-04 20:18:17 <pjorrit> is it faster bruteforcing it or are you doing it for fun?
907 2013-02-04 20:18:22 <kjj> heh. the logs will show that this wasn't my worst moment of dumb in here.

1011 2013-02-04 22:32:52 <HM2> base256 is binary, basically
1012 2013-02-04 22:33:06 clr_ is now known as c00w
1013 2013-02-04 22:33:09 <HM2> not all binary is base256 though :P
1014 2013-02-04 22:33:10 <muhoo> base2 was binary last i checked
1015 2013-02-04 22:33:51 * muhoo goes to re-study his number theory
1016 2013-02-04 22:33:59 <HM2> right, but a 4 bit string isn't base256 unless you pad it to 8 bits, definite a bit order and label it as such
1017 2013-02-04 22:34:21 <gmaxwell> any 2^n base is trivally converted among each other.
1018 2013-02-04 22:34:49 <HM2> muhoo : it basically means it's a string of whole bytes
1019 2013-02-04 22:37:40 <muhoo> right, 25 raw bytes. i was just tripped up by the term base256 i guess. thanks

1041 2013-02-04 23:01:01 <awkorama> Hi everyone. How can I monitor transactions on many addresses in server side situation (e.g. not without any 3rd party) ?
