45 2011-09-30 01:28:19 <imsaguy> star trek didn't really have currency
46 2011-09-30 01:28:23 <imsaguy> they were post scarcity
47 2011-09-30 01:28:44 <imsaguy> in fact, the few times they showed 'trade', it was barter
48 2011-09-30 01:31:41 <shadders> ahh TD... just the chap I need
49 2011-09-30 01:32:10 <shadders> lazy parsing conundrum...
50 2011-09-30 01:32:59 <shadders> since parse could be triggered by any call to a getter or setter, to be safe they should all throw a ProtocolException...
51 2011-09-30 01:33:17 <shadders> not pretty...
52 2011-09-30 01:33:41 <TD> you can rethrow as a RuntimeException IMHO
53 2011-09-30 01:34:12 karnac has joined
54 2011-09-30 01:34:13 <TD> if you want to handle the case of a bad parse but still work lazily, you could always force it to parse with an explicit method
55 2011-09-30 01:34:21 <shadders> I thought of that... but consider the scenario where client receives corrupt message from the wire...
56 2011-09-30 01:34:26 <TD> in most cases parsing won't fail because, eg, you got the data from the block chain
57 2011-09-30 01:34:29 <TD> that is very unlikely
58 2011-09-30 01:34:38 <TD> messages are checksummed by TCP
59 2011-09-30 01:34:52 <TD> think about how often you see an image fail to load in your browser because it got corrupted on the wire
60 2011-09-30 01:35:02 <shadders> then the user is required to catch runtime exceptions with no checked warning that it's needed..
61 2011-09-30 01:35:06 <gmaxwell> TD: Maybe! But I don't think we should let people get away with faulting bitcoin for not obviously handling every crazy corner case they can think of... It's perfectly fine to sometimes answer "then use something other than bitcoin, a world with bitcoin doesn't have to be a world with nothing else"
62 2011-09-30 01:35:21 <shadders> bad client on the other end is the scenario I'm thinking of...
63 2011-09-30 01:35:33 <shadders> sending malformed messages...
64 2011-09-30 01:35:38 <TD> shadders: no, they aren't. they can let the exception propagate and kill the thread. if they care about this possibility they can call parse() which would throw
65 2011-09-30 01:36:06 <TD> shadders: if you care about that you need to parse every message so wouldn't be using the lazy parsing mode right
66 2011-09-30 01:36:17 <TD> shadders: i don't think parsing should always be lazy. it could be optional
67 2011-09-30 01:36:23 <TD> gmaxwell: sure
68 2011-09-30 01:36:29 <shadders> ok true...
69 2011-09-30 01:36:47 <shadders> well atm default is not lazy... can change default behaviour alter..
70 2011-09-30 01:36:48 <TD> unexpected lazyness is annoying. it can cause weird performance issues you don't expect.
71 2011-09-30 01:36:52 <TD> yeah
72 2011-09-30 01:37:19 <shadders> I will make checkParse public as well
73 2011-09-30 01:37:50 <TD> what is checkParse?
74 2011-09-30 01:37:58 <shadders> maybeParse...
75 2011-09-30 01:38:16 <shadders> parse if not already
76 2011-09-30 01:38:42 <TD> right
77 2011-09-30 01:40:23 <shadders> k well if yr happy with runtimeexception I can live with that... it's either that or a duplicate set of getField optField, setField optSetField

151 2011-09-30 03:51:55 <louigi> hey guys! I am on Ubuntu, used the stable version, the 0.3 one since July, several days ago blockcount stopped updating. Today tried running 0.4 - still not updating. Any advice?
152 2011-09-30 03:52:00 <louigi> luke-jr, yep
153 2011-09-30 03:52:05 <louigi> not a lot though - 1!
154 2011-09-30 03:52:39 <luke-jr> louigi: do you have a MtGox account?
155 2011-09-30 03:53:05 HarryS has joined
156 2011-09-30 03:53:19 <luke-jr> also, what OS?
157 2011-09-30 03:53:41 <louigi> luke-jr, I do have an mt gox account though I did not use it yet
158 2011-09-30 03:53:45 <louigi> OS Ubuntu
159 2011-09-30 03:53:58 <louigi> (it is in the first request there ;))
160 2011-09-30 03:54:25 <luke-jr> louigi: could you 1) tar up your ~/.bitcoin directory, 2) send the 1 BTC to your MtGox, 3) post the (compressed) tar somewhere public
161 2011-09-30 03:54:27 <luke-jr> please
162 2011-09-30 03:54:48 <luke-jr> be sure bitcoin is not running before step 1
163 2011-09-30 03:55:00 <luke-jr> (I assume you have already tried restarting it)
164 2011-09-30 03:55:09 <louigi> luke-jr, you mean so that you can look at the wallet and it is empty?
165 2011-09-30 03:55:24 <louigi> luke-jr, yeah, restarted it many times during several days
166 2011-09-30 03:55:29 <luke-jr> louigi: I mean so that if someone you don't trust downloads it, they don't steal your 1 BTC ;)

170 2011-09-30 03:56:03 <louigi> luke-jr, k man, I'll send it! I hope this works too
171 2011-09-30 03:56:04 <gmaxwell> If the blockcount isn't updating, I'd wonder if he's even connected at all?
172 2011-09-30 03:56:14 <louigi> gmaxwell, it does show 8 connections
173 2011-09-30 03:56:23 <luke-jr> gmaxwell: he's not the first time I've heard of this problem
174 2011-09-30 03:56:35 <louigi> 8 connections is the usual number I have
175 2011-09-30 03:56:48 <gmaxwell> luke-jr: Well, if it's connected and stuck my next guess would be that his blockchain has a data error and no future blocks will validate against it.
176 2011-09-30 03:56:50 <luke-jr> gmaxwell: if I can reproduce it, I plan to bisect

178 2011-09-30 03:57:17 <gmaxwell> But yea, if it's actually wallet based that would be interesting.
179 2011-09-30 03:57:49 * luke-jr mostly wants the non-wallet data, but figures it's safest to duplicate as much as possible to try reproducing
180 2011-09-30 03:58:20 <gmaxwell> if it is just blockchain corruption then the send will work fine, though he won't see it confirm locally.
181 2011-09-30 03:58:29 <luke-jr> louigi: btw, you didn't mention: which 0.3 version were you using before?
182 2011-09-30 03:59:14 <louigi> luke-jr, sec, will tell you (got 0.4 running now)
183 2011-09-30 03:59:59 <luke-jr> louigi: please shutdown 0.4, wait 2 minutes, and backup ~/.bitcoin, before doing anything more (like starting the old version again)
184 2011-09-30 04:00:05 <louigi> luke-jr, bitcoin-0.3.24
185 2011-09-30 04:00:07 <luke-jr> k
186 2011-09-30 04:00:29 <luke-jr> the key to fixing this IMO is reproducing it right now
187 2011-09-30 04:00:47 <louigi> k, I sent the bitcoin to my bitmarket.eu account, dunno if it actually arrives there
188 2011-09-30 04:01:09 <gmaxwell> louigi: I think you have good odds of it arriving.
189 2011-09-30 04:01:28 <louigi> k guys, shut down program, waiting a couple of minutes
190 2011-09-30 04:01:30 <gmaxwell> (though you should leave bitcoin running for a few minutes after sending!)
191 2011-09-30 04:01:33 <gmaxwell> doh.
192 2011-09-30 04:02:12 <imsaguy> check bitmarket.eu address against bitcoincharts pending transactions
193 2011-09-30 04:02:12 <gmaxwell> well, it's probably okay.
194 2011-09-30 04:02:16 <luke-jr> ^
195 2011-09-30 04:02:27 <luke-jr> fwiw, I didn't see it in #bitcoin-watch
196 2011-09-30 04:03:20 <luke-jr> louigi: if you want to ensure you only send me the backup, I'll personally guarantee I don't steal it at least :P
197 2011-09-30 04:03:39 <louigi> okay
198 2011-09-30 04:03:49 <louigi> not much to steal there anyway

341 2011-09-30 06:33:58 <AlexWaters> so when a pull becomes un-automatically mergable - it is because of conflicts in the commit?
342 2011-09-30 06:34:09 <AlexWaters> and, this can be remedied by a 'rebase'?
343 2011-09-30 06:34:21 <luke-jr> â¦
344 2011-09-30 06:34:34 <luke-jr> in short, yes
345 2011-09-30 06:34:54 <phantomcircuit> for the long version send milk and cookies
346 2011-09-30 06:35:28 <luke-jr> ^
347 2011-09-30 06:35:28 <AlexWaters> i'm trying to write a general purpose closure warning message. to kill off abandoned pulls, any recommendations?

355 2011-09-30 06:37:10 <AlexWaters> and they just sit there collecting dust
356 2011-09-30 06:37:51 <luke-jr> AlexWaters: then "We really don't want your help. Go away. If you want to persist, rewrite it with our new codebase."
357 2011-09-30 06:37:57 <AlexWaters> lol
358 2011-09-30 06:38:01 <phantomcircuit> i think you'll find that most of those are simple patches which should have been merged but now require a rebase
359 2011-09-30 06:38:28 <phantomcircuit> there isn't overwhelming support for them probably because they scratch an itch

364 2011-09-30 06:45:13 <AlexWaters> does anyone know if notifications are sent out whenever someone edits a comment on a pull? I hate to be flooding people every time I edit my comments with my OCD
365 2011-09-30 06:47:27 <luke-jr> I'd s/automatically/without conflicts
366 2011-09-30 06:47:43 <wumpus> no, notifications are not sent on edits
367 2011-09-30 06:47:48 <luke-jr> your semicolon should be a comma
368 2011-09-30 06:47:49 <wumpus> only when you post the message
369 2011-09-30 06:48:03 <AlexWaters> ok, thanks guys
370 2011-09-30 06:48:03 <luke-jr> s/to be mergable/to merge cleanly
371 2011-09-30 06:48:25 <wumpus> and remember that the original message is in the mail, so sometimes people don't see your edits at all :p
372 2011-09-30 06:49:03 <AlexWaters> yeah, I kind of like that - so that i can tell the participants something without it being very public after editing
373 2011-09-30 06:49:06 <wumpus> (especiallyl if they reply to the mail)
374 2011-09-30 06:49:07 <AlexWaters> like, good job etc

623 2011-09-30 12:17:26 <louigi> I did have my computer freeze
624 2011-09-30 12:17:47 <louigi> and as far as I understand, if I just delete the dat file, it will redownload all blocks from the start - right?
625 2011-09-30 12:18:02 <louigi> luke-jr here guessed there could be some error in blocks
626 2011-09-30 12:18:08 <louigi> so they do not get downloaded anymore
627 2011-09-30 12:18:21 <louigi> I know this - other ppl also have this problem and it would be nice if it gets figured out
628 2011-09-30 12:18:21 <lfm> you gotta delete blk0001.dat AND blkindex.dat
629 2011-09-30 12:18:26 <louigi> yeah
630 2011-09-30 12:18:38 <louigi> that's a lot to redownload though...
631 2011-09-30 12:18:40 <louigi> I might try
632 2011-09-30 12:18:55 <lfm> you can get a restarter file quicker
633 2011-09-30 12:18:55 <louigi> trying
634 2011-09-30 12:19:03 <louigi> from the sourceforge?
635 2011-09-30 12:20:28 <lfm> not sure where the .zip is for the restart data off hand .... looking ....

638 2011-09-30 12:31:48 <louigi> but it might remove my wallet which I do not want...
639 2011-09-30 12:33:32 <lfm> make a backup then
640 2011-09-30 12:33:57 <lfm> it should be just the two files tho
641 2011-09-30 12:35:05 <louigi> lfm, if I make a backup of the wallet
642 2011-09-30 12:35:09 <louigi> wallet.dat?
643 2011-09-30 12:35:12 <louigi> something else?
644 2011-09-30 12:35:12 <lfm> ya
645 2011-09-30 12:35:22 <louigi> and then after I download and get the block count
646 2011-09-30 12:35:25 <louigi> I can copy it in?
647 2011-09-30 12:35:26 <lfm> just need to save wallet.dat

708 2011-09-30 13:38:44 <ThomasV> I just noticed that verifymessage works even for addresses that are not in my wallet. Does it lookup for the public key in the blockchain ?
709 2011-09-30 13:38:56 phungus_ is now known as phungus
710 2011-09-30 13:38:57 <ThomasV> or does it not need the pubkey?
711 2011-09-30 13:39:30 <lfm> it just tests the format of the address and the checksum which is part of the address
712 2011-09-30 13:40:05 <lfm> it doesn't need the pubkey
713 2011-09-30 13:40:06 <gmaxwell> lfm: he's asking about verify message.
714 2011-09-30 13:40:19 <gmaxwell> ThomasV: the signature includes the address, which is all it needs.
715 2011-09-30 13:40:34 <ThomasV> oh it's in the signature
716 2011-09-30 13:40:35 <ThomasV> ty
717 2011-09-30 13:40:42 <gmaxwell> Well, the public key isn't.
718 2011-09-30 13:40:48 <gmaxwell> But it's recovered from the signature.
719 2011-09-30 13:40:55 <gmaxwell> (using the address)
720 2011-09-30 13:41:39 <ThomasV> so, with signature and address, you can recover a pubkey ?
721 2011-09-30 13:41:52 <gmaxwell> (this is a property of ecc signaturesâ given the data and the sig you can recover public keys from them, assuming you have a way of telling if the key is right)
722 2011-09-30 13:42:19 <gmaxwell> (and for us we can use the address to tell if the key is right, and the address is much smaller than the public key itself)
723 2011-09-30 13:42:23 <sipa> ThomasV: using the signature and the message, you can recover the pubkey
724 2011-09-30 13:42:33 <ThomasV> cool
725 2011-09-30 13:42:40 <sipa> but there may be up to 4 candidate pubkeys for a given signature/message combination

728 2011-09-30 13:42:54 <sipa> so the signature contains two extra bits to tell which it is
729 2011-09-30 13:43:08 <ThomasV> I see
730 2011-09-30 13:43:24 <sipa> so only one recovery operation is necessary, and that is compared to the provided address
731 2011-09-30 13:43:54 <ThomasV> ecdsa is magic!
732 2011-09-30 13:44:43 <gavinandresen> Is there consensus on what format public keys should be in the RPC interface? hex? base58? base64 ? I wrote an extension to validateaddress to dump the public key for an address...

811 2011-09-30 15:55:46 <gavinandresen> It'll be 0.5. But I don't want to bump to 0.5 until we have a release candidate.
812 2011-09-30 15:55:57 <luke-jr> O.o
813 2011-09-30 15:56:20 <luke-jr> maybe 0.4.99 in the meantime, like KDE does? :P
814 2011-09-30 15:56:46 <sipa> that's not unreasonable, i think
815 2011-09-30 15:56:55 <gavinandresen> Is that how KDE does it? Release number versioning policy is something I should care more about, but just don't
816 2011-09-30 15:57:02 wpl has joined
817 2011-09-30 15:57:13 <luke-jr> well, KDE starts at like .98 for beta, then uses .99 for RCs
818 2011-09-30 15:57:30 <luke-jr> or something like that
819 2011-09-30 15:57:40 <luke-jr> maybe it's .8x for betas and .9x for RCs, I forget exactly
820 2011-09-30 15:58:26 <sipa> luke-jr: and then you'd use 0.4.{1-x} for the backport release?
821 2011-09-30 15:58:38 <luke-jr> sipa: right
822 2011-09-30 15:58:57 * luke-jr renames the 'stable' branch to '0.4.x'

833 2011-09-30 16:01:59 <luke-jr> genjix: it does with 0.3.24 apparently, at least
834 2011-09-30 16:02:08 <luke-jr> and no version from 0.3.20 to 0.4 can recover from it
835 2011-09-30 16:02:16 <luke-jr> the block download just locks up permanently

837 2011-09-30 16:02:38 <genjix> when ProcessBlock is called, it should check in ConnectBlock whether the new work is bigger than the last one + this current difficulty

856 2011-09-30 16:07:21 <genjix> sipa: hmmm
857 2011-09-30 16:07:26 <genjix> let me check
858 2011-09-30 16:08:20 <genjix> sipa: yes it is a possibility
859 2011-09-30 16:08:22 <sipa> downloading again won't fix it, because the client considers the block already known (will not respoend to inv)
860 2011-09-30 16:08:24 <genjix> AddToBlockIndex
861 2011-09-30 16:08:36 <luke-jr> [08:07:02] <louigi> I did have my computer freeze
862 2011-09-30 16:08:43 <sipa> and subsequent block downloads will only try to connect to tip, making them all orphan
863 2011-09-30 16:09:03 <luke-jr> so the solution is to recover somehow I guess
864 2011-09-30 16:09:39 <sipa> removing that block from the blockdb should suffice then
865 2011-09-30 16:09:43 <genjix> its tough though since the further checks depend on it being added to the chain
866 2011-09-30 16:09:57 <luke-jr> sipa: this problem is fairly common-- recovery should be automatic ;p
867 2011-09-30 16:10:00 <genjix> so you cannot just add it to the chain *after* it's been validated
868 2011-09-30 16:10:16 <sipa> hmmm it seems not too hard
869 2011-09-30 16:10:33 <luke-jr> genjix: could you add it with a "not yet processed" flag?
870 2011-09-30 16:10:37 <sipa> when loading the chain, if the work is >> tip.work, reprocess

875 2011-09-30 16:12:11 <luke-jr> hmm
876 2011-09-30 16:12:15 <luke-jr> I think that makes sense
877 2011-09-30 16:12:30 <luke-jr> there should never be a work higher than the best, right?
878 2011-09-30 16:12:40 <luke-jr> since the existence of it implies the "best" isn't really the best
879 2011-09-30 16:12:53 <genjix> i don't think that's ideal
880 2011-09-30 16:12:58 <genjix> a flag is best
881 2011-09-30 16:13:11 <luke-jr> is height recorded on blocks in the db?
882 2011-09-30 16:13:18 <genjix> since there's still other things that happen after adding it to the block chain
883 2011-09-30 16:13:35 <luke-jr> genjix: after setting it as 'best'?
884 2011-09-30 16:13:45 Diablo-D3 has joined
885 2011-09-30 16:13:48 <genjix> so a flag like 'fValidationComplete'
886 2011-09-30 16:14:06 <genjix> and once the entire ProcessBlock main body is done, that flag gets set on the block
887 2011-09-30 16:14:10 <phantomcircuit> so sad
888 2011-09-30 16:14:18 <phantomcircuit> i have to de normalize the intersango database
889 2011-09-30 16:14:22 <luke-jr> would adding it as an orphan first work?
890 2011-09-30 16:14:27 <genjix> when loading the chain, blocks without that set are re-processed
891 2011-09-30 16:14:28 <phantomcircuit> joining orders and limit orders is just too slow
892 2011-09-30 16:14:42 <phantomcircuit> and the schema was so pretty :(
893 2011-09-30 16:15:01 <sipa> the real solution is making the adding of the block to the db, and processing it atomic
894 2011-09-30 16:15:04 <sipa> no?
895 2011-09-30 16:15:09 ThomasV has quit (Quit: Leaving)
896 2011-09-30 16:15:12 <genjix> yeah
897 2011-09-30 16:15:30 <sipa> since having a block in the database that has higher work, but isn't in the main chain, is considered an inconsistancy
898 2011-09-30 16:15:31 <genjix> but not much you can do i suppose if bitcoin freezes halfway
899 2011-09-30 16:15:42 <sipa> eh, bdb has locking
900 2011-09-30 16:15:59 <sipa> it should support transactionality
901 2011-09-30 16:16:21 <gavinandresen> it does
902 2011-09-30 16:16:54 <luke-jr> I like sipa's solution
903 2011-09-30 16:16:59 <luke-jr> reprocess blocks higher than best
904 2011-09-30 16:17:56 <genjix> and you commit at the end, right?
905 2011-09-30 16:18:00 <genjix> that should work too
906 2011-09-30 16:18:13 <genjix> probably the most elegant method
907 2011-09-30 16:18:50 <sipa> not committing before the block is processed is the only solution (note: i haven't checked the code now, all i say is based on assumptions)
908 2011-09-30 16:19:24 <genjix> well it should be ok afaik, since none of the current info is loaded. it only uses the data in memory
909 2011-09-30 16:19:39 <luke-jr> sipa: it doesn't solve it, though.
910 2011-09-30 16:19:45 <genjix> and the only things which are loaded are previous blocks/txs... which should be committed anyway
911 2011-09-30 16:19:52 <sipa> it won't solve the problem for old clients with corrupted databases
912 2011-09-30 16:20:12 <sipa> and recovery from almost-impossible situations in general is probably wanted, just for stability
913 2011-09-30 16:20:19 <luke-jr> we get the same transaction behaviour I think if we just delete blocks higher than <best> at load too
914 2011-09-30 16:20:34 <sipa> luke-jr: check, that's a lot easier
915 2011-09-30 16:20:39 <luke-jr> sipa: it's not almost impossible, lots of people have had this issue
916 2011-09-30 16:20:40 <genjix> might be an idea instead of trying to have catch alls for all situations
917 2011-09-30 16:20:48 <genjix> instead to have good tools to recover
918 2011-09-30 16:21:16 <sipa> luke-jr: that also fixes further orphans
919 2011-09-30 16:22:08 <luke-jr> downside to that is, it might potentially destroy real orphans which may be desired for forensics at some point
920 2011-09-30 16:22:28 <luke-jr> I suppose instead of deleting, the first octet could be changed to '1' (never happens in real blocks)

940 2011-09-30 17:03:21 <luke-jr> <luke-jr> gavinandresen: btw, kinda up in the air whether your "DoSprevention" code should be merged to stable or not (it's on the boundary of bugfix and feature); what do you think?

943 2011-09-30 17:03:47 <gavinandresen> I dunno. I'm not a huge fan of "stable" before a bitcoin 1.0 release
944 2011-09-30 17:04:17 <gavinandresen> "Here's a stable version of this beta experimental doo-hickey...." is kind of a mixed message
945 2011-09-30 17:04:27 zhoutong has joined
946 2011-09-30 17:05:02 <gmaxwell> luke-jr: if you don't merge it, and some transitive vulnerablity slips through, your 'stable' nodes will end up getting themselves partitioned from the rest of the network.
947 2011-09-30 17:05:25 <gmaxwell> e.g. if antiDOS nodes hang up on nodes that forward something only a non-antidos node would forward.
948 2011-09-30 17:05:29 <luke-jr> or vice-versa :p
949 2011-09-30 17:05:43 <gmaxwell> I guess I could argue it both ways based on that.
950 2011-09-30 17:05:52 <gmaxwell> Depending on what nodes I expect to be more popular.
951 2011-09-30 17:06:02 <luke-jr> even 0.4 is a minority still
952 2011-09-30 17:06:20 <gmaxwell> E.g. if non-stable nodes are more popular you very much want the antidos code. If stable nodes are more popular then you could go either way.
953 2011-09-30 17:06:32 <gmaxwell> (assuming that kind of bug)
954 2011-09-30 17:06:34 <luke-jr> gmaxwell: but I guess your point is that the real question is "should stable track protocol changes?"
955 2011-09-30 17:06:52 <gavinandresen> gmaxwell: by the way, I've been thinking about a point you made RE: getting old clients to upgrade. I'm starting to think that planned obsolescence might be a very good idea.
956 2011-09-30 17:07:18 <gmaxwell> obviously that would need to be done with great care.
957 2011-09-30 17:07:41 <luke-jr> gavinandresen: that defeats the entire point of keeping protocol compatibility
958 2011-09-30 17:07:52 <luke-jr> right now, at least
959 2011-09-30 17:08:10 <gmaxwell> It doesn't defeat it, because planned could still have a long horizon.
960 2011-09-30 17:08:20 <gmaxwell> (or even a way to override)
961 2011-09-30 17:08:59 <gavinandresen> If I recall correctly, very-very old version of bitcoin will stop working in February.
962 2011-09-30 17:09:17 <gavinandresen> Yeah: net.h: // Version 0.2 obsoletes 20 Feb 2012

964 2011-09-30 17:11:10 <gmaxwell> luke-jr: e.g. I don't know if we'd ever want want to maintain the code for it, but you could require that old nodes be placed behind new nodes which are explicitly ACLed to allow them. Thus getting them off the public network even if people continue to run them in private.

1002 2011-09-30 18:16:08 <genjix> just curious.
1003 2011-09-30 18:16:10 <gmaxwell> When BlueMatt and I attempted a hash locked txn it wouldn't actually confirm on eligius.
1004 2011-09-30 18:16:21 <tcatm> gavinandresen: so your plan is to remove cryptopp in 0.5?
1005 2011-09-30 18:16:27 <luke-jr> gmaxwell: should be
1006 2011-09-30 18:16:39 <genjix> i.e if i design a tx mem pool, then i also have scope for planning too
1007 2011-09-30 18:16:44 <luke-jr> gmaxwell: you probably just had trouble keeping it in Eligius's queue :P

1048 2011-09-30 19:07:24 <Blitzboom> genjix: lol, i wish!
1049 2011-09-30 19:07:32 clr_ is now known as c00w
1050 2011-09-30 19:07:45 <luke-jr> "suffering"
1051 2011-09-30 19:07:50 <Blitzboom> give me all the deflationary death spiral thatâs possible
1052 2011-09-30 19:07:52 <luke-jr> people spending less is a GOOD thing
1053 2011-09-30 19:08:05 <genjix> im not an economist
1054 2011-09-30 19:08:21 <genjix> but this applies to everyone in the bitcoin community, http://rationalwiki.org/wiki/Engineers_and_woo
1055 2011-09-30 19:08:43 <genjix> lets not talk hand wave and dismiss ideas far outside our knowledge domain
1056 2011-09-30 19:09:10 <Blitzboom> iâm not dismissing it
1057 2011-09-30 19:09:21 <genjix> "But engineers as a group have a noted, and indeed quantified, tendency to pontificate on things well outside their area of expertise, to the point of actual fallacy."
1058 2011-09-30 19:09:24 <Blitzboom> just saying i would welcome a deflationary spiral as long as i profit from it
1059 2011-09-30 19:09:34 <genjix> i would not
1060 2011-09-30 19:09:51 <luke-jr> genjix: that wiki is obviously ridiculous
1061 2011-09-30 19:09:55 <log0s> the idea of something becoming so valuable it becomes worthless contradicts itself

1063 2011-09-30 19:10:03 <Blitzboom> luke-jr: because it is not religious?
1064 2011-09-30 19:10:09 <luke-jr> it fails on even the most basic concepts
1065 2011-09-30 19:10:14 <genjix> bitcoin has value because it is a mechanism of trade
1066 2011-09-30 19:10:19 <luke-jr> for example, mathematics is not only science, but it is one of the few /formal/ sciences
1067 2011-09-30 19:10:20 <genjix> not because it is rare
1068 2011-09-30 19:10:24 <Blitzboom> no, bitcoin has value because it has value
1069 2011-09-30 19:10:32 <Blitzboom> it has nothing to do with trade, itâs circular
1070 2011-09-30 19:10:41 <luke-jr> yet that wiki basically outright says mathematics is distinct from science
1071 2011-09-30 19:10:46 <genjix> my spit is rare. doesn't make it valuable.
1072 2011-09-30 19:11:01 <Blitzboom> genjix: bitcoin is valuable because of future projections
1073 2011-09-30 19:11:05 <genjix> luke-jr: it is different.
1074 2011-09-30 19:11:08 <Blitzboom> and because it was valuable in the past
1075 2011-09-30 19:11:15 <luke-jr> genjix: nope
1076 2011-09-30 19:11:17 <ThomasV> my spit is $100/ml
1077 2011-09-30 19:11:25 <genjix> mathematics uses axioms to prove theorems
1078 2011-09-30 19:11:37 <Blitzboom> it doesnât matter what kind of trade is conducted with it as long as peopleâs "illusion" of value is maintained
1079 2011-09-30 19:11:53 <genjix> science uses empirical evidence and theories to explain things as best as it can
1080 2011-09-30 19:12:07 <genjix> but nothing is ever proven. difference in methodology
1081 2011-09-30 19:12:12 <luke-jr> genjix: your own cluelessness doesn't make this wiki any more clueful ;)

1084 2011-09-30 19:19:10 <genjix> luke-jr: have you seen this guy? http://www.youtube.com/watch?v=nLbTE56HqLE - even if you don't agree with him (and i can understand both ways), it's really interesting for me to understand the other POV
1085 2011-09-30 19:19:20 <genjix> not having had any religious background :)
1086 2011-09-30 19:19:48 <genjix> idk thought you might enjoy that...
1087 2011-09-30 19:19:55 <luke-jr> why would I?
1088 2011-09-30 19:20:16 <genjix> his story is thought provoking and interesting
1089 2011-09-30 19:21:09 <genjix> well he has a strong maths/computing background and describes using mathematical analogies how/why he went from changing his entire belief system.
1090 2011-09-30 19:21:25 <genjix> it works both ways, and is an interesting expose into psychology
1091 2011-09-30 19:22:34 <genjix> starts getting good at part 2.0
1092 2011-09-30 19:24:15 <luke-jr> he didn't change his entire belief system really
1093 2011-09-30 19:24:44 <genjix> how? seems he did.
1094 2011-09-30 19:24:57 <luke-jr> if he did, he would abandon morality
1095 2011-09-30 19:24:58 <luke-jr> entirely
1096 2011-09-30 19:25:18 <genjix> where do you believe morality comes from? yourself?
1097 2011-09-30 19:25:21 <luke-jr> God
1098 2011-09-30 19:25:32 <genjix> so can god decide what is moral and what is not?
1099 2011-09-30 19:25:40 <luke-jr> He defines morality, yes.
1100 2011-09-30 19:25:46 <genjix> can he say murder and rape is moral just because he says so?
1101 2011-09-30 19:25:51 <luke-jr> He could.
1102 2011-09-30 19:25:52 <genjix> or is morality outside god?
1103 2011-09-30 19:26:06 <luke-jr> but then it wouldn't be murder, since murder is defined as unlawful
1104 2011-09-30 19:26:46 <genjix> so what is moral, is simply what god decides is moral?
1105 2011-09-30 19:26:46 <gavinandresen> so speaking of morality... I haven't had any feedback on my DoSorphans patch
1106 2011-09-30 19:27:09 <luke-jr> genjix: moral/good = conforming to God's will
1107 2011-09-30 19:27:52 <genjix> why do people pray then? isn't that trying to change god's will?
1108 2011-09-30 19:27:59 <luke-jr> no
1109 2011-09-30 19:28:11 <luke-jr> prayer changes the person praying
1110 2011-09-30 19:28:12 <genjix> but god has a plan for you.
1111 2011-09-30 19:28:19 <luke-jr> their disposition, etc

1164 2011-09-30 20:58:01 <genjix> what is the reason/argument for using int64 with bool MoneyRange(value) { 0 <= value && value <= MAX_MONEY; } versus using uint64_t and bool MoneyRange(value) { value <= MAX_MONEY; } ?
1165 2011-09-30 20:58:17 <genjix> surely the latter protects against overflow errors much better?
1166 2011-09-30 20:58:35 <genjix> well to the same degree
1167 2011-09-30 20:58:39 WakiMiko_ has quit (Ping timeout: 240 seconds)
1168 2011-09-30 21:00:03 <gmaxwell> genjix: mixing unsigned int in C can lead to surprising bugs due to the implicit type promotion rules.
1169 2011-09-30 21:01:11 <genjix> that works both ways

1174 2011-09-30 21:04:09 <gmaxwell> Well, the promotion rule only works one way. Emperically on 32bit+ it's the unsigned type that tends to be the guilty one (I think my expirence on 16 bit machines is actually the opposite, and the promotion rule is pretty helpful there) ::shrugs:: ymmv.

1176 2011-09-30 21:16:17 <lfm> I think the money type is signed to support debts and overdrawn accounts and stuff even tho its not used reall with bitcoin. and as you say, it works to the same degree The compiler might even optimize it internally the way you are asking us to manually.
1177 2011-09-30 21:16:42 <gmaxwell> it almost certantly does.
1178 2011-09-30 21:17:34 <gmaxwell> Usually signed types actually lead to better compiled code anywaysâ signed overflow is formally undefined (not even implementation defined) and the compiler can optimize accordingly.
1179 2011-09-30 21:21:05 <helo> it is dangerous to use unsigned for monetary values... when you accidentally make it < 0 it just asplode
1180 2011-09-30 21:21:26 <helo> if you write casino games ;)

1242 2011-09-30 22:31:30 <lfm> but the internal miner reports hash speed in kh/s and it looks like you'r using the wrong unit in the ;;bc,calcd
1243 2011-09-30 22:31:42 <lfm> or h/s
1244 2011-09-30 22:31:56 <tcatm> oh, that might be the problem ;)

1264 2011-09-30 22:42:49 <tcatm> 64kbit/s internet can be annoying :)
1265 2011-09-30 22:43:35 <tcatm> so if you could compile bitcoind for testnet-in-a-box can you try current master branch and compare results to https://github.com/tcatm/bitcoin/tree/no-cryptopp ?
1266 2011-09-30 22:44:14 <lfm> tesnetinabox works with standard binaries
1267 2011-09-30 22:45:04 <lfm> ill try with 0.4.0 first unless you really need me to get master branch
1268 2011-09-30 22:45:49 <lfm> 0.4.0 is generating with my testnetinabox setup
1269 2011-09-30 22:45:52 <tcatm> 0.4.0 should be fine, too

1285 2011-09-30 22:53:11 <lfm> ya I would think it would
1286 2011-09-30 22:53:18 <tcatm> IIRC that was added to allow 4way to work
1287 2011-09-30 22:54:00 <lfm> ya, the see alignments are special

1302 2011-09-30 23:00:02 <luke-jr> scrap the internal miner and embed cgminer

1306 2011-09-30 23:00:25 <luke-jr> cgminer is CPU or GPU
1307 2011-09-30 23:00:31 <lfm> mine is a Q9450 at 2.0ghz
1308 2011-09-30 23:00:56 <lfm> tcatm: ya cgminer does either cpu or gpu

1314 2011-09-30 23:03:12 <lfm> oh ok
1315 2011-09-30 23:03:45 <lfm> put a bigger cooler on it -> itll go faster?
1316 2011-09-30 23:04:09 <tcatm> probably, but not that easy on a laptop
1317 2011-09-30 23:04:21 <lfm> oh ya ok

1346 2011-09-30 23:30:52 <tcatm> I don't think that will work with the current scripting implementation but I might not have fully understood it.
1347 2011-09-30 23:31:29 <lfm> I dont think so either. It is not clear what are the "conditions" for awarding either A or B.
1348 2011-09-30 23:31:33 <luke-jr> looks like nonsense imo
1349 2011-09-30 23:32:36 <lfm> luke-jr I tend to agree but I was trying to be nice for once

1351 2011-09-30 23:33:14 <bitanarchy> lfm: could be any readable condition like "superluminous neutrinos are confirmed at certain date"
1352 2011-09-30 23:33:38 <bitanarchy> sure I probably make a mistake... but what is the mistake?
1353 2011-09-30 23:34:11 <lfm> ok, thats sounding more certainly like intenable nonsense. the whole beauty of the bitcoin block chain is that it is self contained in a sense.
1354 2011-09-30 23:35:23 <tcatm> won't work. whatever the condition is it would have to be verifyable by a computer.
1355 2011-09-30 23:35:31 <bitanarchy> lfm: what do you mean with self-contained? By the way... I am not suggesting to implement it in bitcoin... but it could be a seperate experimental currency.
1356 2011-09-30 23:35:42 <lfm> you seem to be adding all sorts of outside "deciders" like a wiki and now some neutrinos.
1357 2011-09-30 23:36:32 <bitanarchy> lfm: yes, I want the community to decide whether a condition used for a transaction is false or true
1358 2011-09-30 23:36:47 c00w has joined
1359 2011-09-30 23:37:12 <lfm> with the block chain as it is you can figure out where every bitcoin ever created is now and every where it has ever been. (by location I mean attached to certain bitocin "addresses".
1360 2011-09-30 23:37:21 <tcatm> bitanarchy: try to solve that problem (i.e. prevent cheating and all that) without adding a currency first :)
1361 2011-09-30 23:39:21 <lfm> bitanarchy: it would be an incredible complication of the security and provability if we had to somehow take into account the status of some wiki page or some neutrino
1362 2011-09-30 23:40:27 <gmaxwell> bitanarchy: one challenge is that if it has monolithic blocks like bitcoin you'll have problems where I accept 99% of the txn in a block but 1% I reject... and someone else rejects a different 1% and so on...
1363 2011-09-30 23:41:23 <casascius> https://en.bitcoin.it/wiki/Casascius_Bitcoin_POS_system
1364 2011-09-30 23:46:15 <bitanarchy> gmaxwell: why do miners reject false transactions right now?
1365 2011-09-30 23:46:56 <bitanarchy> ah, ok because the whole block will be rejected...
1366 2011-09-30 23:49:19 <gmaxwell> Right. Alternatively ask "why do miners not cheat and insert crap transactions that are invalid" because it makes the whole block invalid.
