Transcript for #bitcoin-dev 2010/12/15

00:01 ByteCoin May I post your code to the forum. I believe it may suffer from a similar flaw to appamatto's
00:01 ByteCoin please?
00:01 ByteCoin I will post a reply with my findings...
00:01 ByteCoin Will take some time though...
00:01 ByteCoin Happy to discuss
00:02 ByteCoin now
00:02 ArtForz sure, whatever
00:02 ByteCoin ish
00:02 ArtForz I knwo it's inaccurate
00:02 ByteCoin Cool. Thx
00:02 ArtForz doesnt properly model race situations
00:03 ByteCoin I'm suspicious that because you "generate blocks" in two places in the code it's not counting things properly...
00:03 ArtForz huh?
00:04 ByteCoin It's hard to explain at this time of night...
00:05 ByteCoin Suffice to say, that if I submit a string of ACCAACCAAACC data in place of your random function, the results should be essentially the same regardless of whether I miss off one character from the start of the string. Do you agree?
00:06 ArtForz errr. not quite
00:06 ByteCoin The choice of whether the next block was generated by A or C has a different effect depending on where it occurs in the code.
00:06 ByteCoin Artforz explain why not quite?
00:07 ArtForz you're missing the case of next block found by A and C
00:07 ByteCoin Ok. I thought you might mention that,...
00:08 ArtForz = A and C both finding a block in one timestep without knowing about the other side
00:08 ByteCoin So if I submit a string of ACCAABAACCCB etc where B indicates that the next block is found by A and C then you would be happy??
00:08 ArtForz thats also why increasing the timestep causes more races
00:08 ArtForz yup
00:09 ArtForz I'm completely restructuring it anyways
00:09 ByteCoin If one symbol is missed off the start of any arbitrary sequence of plausible ACB characters then it should have a negligable effect on the overall outcome?
00:09 ArtForz sure
00:10 ArtForz 2 "A" populations for tiebreaking
00:10 ByteCoin I will aim to show that your program is defective by finding a string where missing off one initial character produces very different results.
00:10 ArtForz thats easy
00:11 ArtForz "AC"
00:11 ByteCoin You would accept that such a string would demonstrate a flaw in your program. We're talking LOOOONG strings
00:11 ArtForz errr... no
00:11 ByteCoin Strings millions of characters long.
00:12 ArtForz lets see
00:12 ByteCoin I thought you agreed to "if one symbol is missed off the start of any arbitrary sequence of plausible ACB characters then it should have a negligable effect on the outcome"
00:13 cosurgi tell me: I need to patch bitcoind in order to allow communication between it and poclbm. Which version of bitcoind I have to patch? Where is the patch?
00:13 cosurgi (OpenCL 2.1 on my ATI seems to work fine)
00:13 ArtForz btw, who wins for a B ?
00:13 tcatm cosurgi: no patch needed :)
00:14 cosurgi oh!
00:14 ArtForz and of course you need to have the proper weighting of events
00:15 ByteCoin B means that both A_found_block and C_found_block are set to true at the same time
00:15 ByteCoin B= both
00:15 ArtForz well, as long as the relative occurences of ABC arent skewed, it should work
00:16 tcatm what about just trying it on a custom testnet?
00:16 cosurgi tcatm: is it going to work if both poclbm and bitcoind will be both calculating hashes? Or I need to disable it for bitcoind ?
00:16 ByteCoin Artforz: Fair enough. I will ser to work tomorrow.
00:16 ByteCoin set
00:16 tcatm cosurgi: better disable it for bitcoind. It's only a waste of energy.
00:17 cosurgi ok
00:17 cosurgi -gen=0
00:18 ByteCoin Artforz: Just explain a little about what A_chain and C_chain represent?
00:18 ByteCoin plz
00:18 ArtForz current block count in the respective chains
00:18 ArtForz total public chain is A_won_blocks + C_won_blocks
00:20 ByteCoin Ok. I'm getting there....
00:21 cosurgi wow.
00:22 cosurgi 205 Mhs/sec on ATI 5830
00:22 cosurgi ;;bc,calc 205820
00:22 gribble The average time to generate a block at 205820 Khps, given current difficulty of 12252.03471156 , is 2 days, 23 hours, 1 minute, and 10 seconds
00:22 cosurgi is that a speed that you'd expect from ATI 5830 ?
00:23 tcatm cosurgi: looks right
00:23 cosurgi good :)
00:23 ArtForz yep
00:24 cosurgi thanks :)
00:24 ArtForz http://pastebin.com/AvymGnMJ
00:24 ByteCoin I take it back about your program suffering the same flaw....
00:25 ByteCoin Funny how everyone visualizes the same thing in different ways....
00:27 cosurgi --frames=1 gives 209 Mhs/s
00:27 cosurgi anything else I could finetune ?
00:27 ArtForz hurrm, thats actually pretty damn good
00:27 cosurgi wow, now it's even 210 MHs/c
00:28 ArtForz using m0s miner?
00:28 cosurgi ...oscillating between 209 and 210
00:28 cosurgi yes
00:28 tcatm overclocked?
00:28 cosurgi ~/m0/m0mchil-poclbm-1e3b163$
00:28 cosurgi no.
00:29 ArtForz thats... weird
00:29 cosurgi I just bought that ATI today. I only: inserted that into box (had some problems with cables, etc..) upgraded to debian squeeze, installed ati drivers and opencl, and I've just run that miner. nothing else.
00:29 cosurgi I don't even knopw how to overclock this :)
00:30 ArtForz my table is 95% of theoretical peak
00:30 cosurgi I can paste you some specs of this card
00:30 ArtForz diablos miner is around there, m0s is usually a tad slower
00:30 cosurgi just give me the commands you want me to run
00:30 cosurgi it's all remote terminal, so no fancy GUI fglrc-stuff allowed
00:30 cosurgi *fglrx-stuff
00:31 ArtForz so m0s suddenly getting 97.3% theoretical peak is... unexpected
00:31 cosurgi 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon HD 5800 Series (Cypress LE)
00:31 cosurgi ArtForz: where's diablo's miner? :)
00:32 ArtForz http://www.bitcoin.org/smf/index.php?topic=1721.0
00:32 cosurgi thanks, checking.... :)
00:32 ArtForz openCL miner written in java
00:41 fabianhjr I got 0.10 BTC to spare. Anyone have a suggestion on what to spend them on?
00:41 AAA_awright Donation?
00:41 AAA_awright Give it back to the faucet you stole it from
00:41 donpdonp 2oz of Four Loco
00:41 AAA_awright ;)
00:43 fabianhjr WTF are you talking about? I got them to spare, so I was thinking on getting some kiba's art.
00:43 AAA_awright Woa
00:43 AAA_awright ...kiba has art?
00:43 cosurgi thats 2 cents actually :)
00:44 fabianhjr http://www.bitcoin.org/smf/index.php?topic=1929.0
00:45 kiba a long running thread of kiba's art project
00:45 kiba I barely colored the girl's head lol
00:49 fabianhjr kiba: which one is your favourite.(I can only buy one atm)
00:49 doublec !pool
00:51 kiba fabianhjr: they are just the same art piece
00:51 kiba and it's a work in progress
00:52 kiba the latest image is the latest revision
00:52 kiba and oldest image is the ugliest
00:52 fabianhjr Oh! Do you have any finished work I could use to promote BitCoins(Planing on selling posters and tshirts)
00:52 doublec ;;bc,calc 200000
00:52 gribble The average time to generate a block at 200000 Khps, given current difficulty of 12252.03471156 , is 3 days, 1 hour, 5 minutes, and 10 seconds
00:53 da2ce7 Proposal Two: Named Addresses is done http://domainchain.org/wiki/doku.php?id=bitname 2/3rds complete.
00:53 AAA_awright I wonder if I could sell music like that...
00:55 fabianhjr well, I am actually setting up a pledge for an easy to use PrestaShop module to accept BitCoins as payments. You are welcomed to claim them anytime(Currently mining them)
00:56 fabianhjr That could help many actually offer products with BitCoins
00:57 kiba fabianhjr: no. If I was finished, I would already have a t-shirt in print production :P
01:02 fabianhjr Ok.
01:05 xelister USA payed people to troyan/backdoor opensource kernels, reports OpenBSD developer. This then probably is true also for Linux. Damn USA spies everywhere, what the hell.
01:07 da2ce7 http://domainchain.org/wiki/doku.php?id=bitname
01:07 da2ce7 done :) well i'm going to flesh it out a bit... what do you think?
01:11 xelister http://bsd.slashdot.org/story/10/12/15/004235/FBI-Alleged-To-Have-Backdoored-OpenBSDs-IPSEC-Stack
01:11 fabianhjr xelister, just sniff the traffic from any given box for a week after a kernel upgrade. Search for anything out of ordinary and boom. You got them.
01:12 fabianhjr Tough, a commit passes trough a lot of revision before it gets pushed to the mainline, 0_o
01:15 cosurgi hmm.. problems with diablo miner
01:15 cosurgi Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/bitcoin/diablo-miner/DiabloMiner/target/libs/natives/linux/liblwjgl.so: /usr/lib/jvm/java-6-sun-1.6.0.22/jre/lib/i386/libjawt.so: symbol awt_FreeDrawingSurface, version SUNWprivate_1.1 not defined in file libmawt.so with link time reference
01:16 cosurgi export DISPLAY=:0 seems to have fixed this
01:16 cosurgi [15.12.10 03:16:07] Started
01:16 cosurgi [15.12.10 03:16:17] Added Cypress (#1) (14 CU, local work size of 256)
01:16 cosurgi Waiting...
01:16 cosurgi huh??
01:17 cosurgi 213624 khash/sec\n105517
01:18 cosurgi it is now oscillating between 212 and 214
01:18 ArtForz guess you got a fast card
01:18 cosurgi :-D
01:19 ArtForz happens sometimes, one of my 5970s is also doing this
01:19 cosurgi is there a C++ OpenCL miner somewhere?
01:19 ArtForz I dont think so
01:20 cosurgi ok. so maybe I'll look at that java code and rewrite it into C++
01:20 ArtForz would be nice, needing JRE on miners is inconvenient
01:20 xelister fabianhjr: what?
01:21 fabianhjr ?
01:21 cosurgi but I still don't get what miner is doing. I only know that it wants to find hashes that start with zeros.
01:21 xelister fabianhjr: I dont get you ;) how is tracking devel box traffic going to help any shit?
01:21 cosurgi care to say shortly exact procedure?
01:21 fabianhjr xelister: if you sniff for a week the keylogger must send the log at least once. Then you will know for sure.
01:21 xelister United States of American fucking government (allegedly) paid developer to 'donate' troyaned code to open source kernels like openbsd
01:21 fabianhjr If you develop a Keylogger you want a way to access the logs.
01:22 xelister fabianhjr: also, what you say is fucking stupid
01:22 fabianhjr Why?
01:22 xelister fabianhjr: I could even hide the keylogger report (if that would be the use of the troyan) in timing informations of regular trafic
01:22 xelister no "watching" would detect such stenography
01:22 cosurgi wow. it has just hit 216 MHs/s
01:23 cosurgi now back to 213
01:23 fabianhjr xelister: if you stego something you still have to send it.
01:23 xelister fabianhjr: no
01:23 xelister fabianhjr: just variate timing of the NORMAL traffic a bit, and use this tiny time drifts as bits of your steno
01:24 fabianhjr Yeah, you neeed a way to get the logs from the victim to the attacker.
01:24 xelister <xelister> fabianhjr: just variate timing of the NORMAL traffic a bit, and use this tiny time drifts as bits of your steno
01:24 ArtForz yes, but hiding something like that in open source code... good luck
01:24 xelister perhaps this attack is too complex for you to understand though, fabianhjr
01:25 xelister ArtForz: it happened. Attacker: USA gov, target: OpenBSD kernel. Already done (allagedly, they are now verifying how bad the backdoor was and how much that code is still in use today)
01:25 fabianhjr What you are saying is that you can send data from point A to point B by sneding this data to a random point C and hope it routes to you?
01:25 fabianhjr Oh!
01:25 xelister ArtForz: http://bsd.slashdot.org/story/10/12/15/004235/FBI-Alleged-To-Have-Backdoored-OpenBSDs-IPSEC-Stack...
01:25 ArtForz backdoor != keylogger
01:26 xelister fabianhjr: duuh yeah. Just bribe/mob the ISP of either point A or C. That is what thugs and criminals like usa gov can do well
01:26 fabianhjr You mean like them reading the actual routing? That would cause a massive lag and would be clearly notisable.
01:26 xelister fabianhjr: boy you are so naive its even not funny, this FBI is doing for many years
01:26 ArtForz hiding something like messing up a DH key exchange so it accepts certain "invalid" keys is a LOT easier than hiding a full blown keylogger
01:27 xelister fabianhjr: actually, for example USA ISPs are REQUIRED BY LAW to prepare equipment for the FBI/other thugs to easly listen on your traffic, on ISP level
01:27 fabianhjr ArtForz got a point
01:27 fabianhjr xelister: I am not aware of USA regulations, I apologies.
01:27 xelister also, for ISP logging all packages times/src/dst is triviall. Even I do it right now
01:28 xelister and recording it is trivial, and of course introduces no lag
01:28 fabianhjr Doesn't it cause a lot of lag?
01:28 xelister I do it RIGHT NOW, of course it makes NO LAG
01:28 xelister ok perhaps a 0.00001 sec lag
01:28 xelister if the router would be a pentium I
01:28 fabianhjr So, let me guess, you cannot filter, however, you make a copy of each packet and send it to another machine for loggging?
01:29 xelister if computer A have backdoor in firewall stack, then I could steal any information from this computer
01:29 fabianhjr Sorry, I am newb and I am catching up.
01:30 xelister computer A sends the packets with a tiny time variance. or special way of 'random' afair cookies or port numbers and so on
01:30 xelister and this tiny bits can be used as stenography
01:30 fabianhjr Ok
01:30 fabianhjr Yeah, I agree.
01:30 xelister computer A sends to A's ISP, it send to backbone, it sends to other backbone etc
01:30 noagendamarket I guess since its open source the governemnent can contribute code :)-
01:31 xelister if A's ISP is for example in USA then it is required to allow fully logging. Then get logs, compare times, filter out noise, and you have the data
01:31 xelister and that is just one of ideas
01:31 xelister anyway, that are the tech details
01:31 xelister the poins was, USA are fucking dick faggots,
01:31 noagendamarket lol
01:31 xelister for hiring coders to plant backdoors even in open source kernels
01:31 noagendamarket You can do that when you can print all the cash you need
01:31 xelister imho this is even bigger as USA idiots gathering DNA of world leaders and NATO leaders
01:32 xelister anyway this stroy is developing now, on http://bsd.slashdot.org/story/10/12/15/004235/FBI-Alleged-To-Have-Backdoored-OpenBSDs-IPSEC-Stack and http://www.reddit.com/r/programming/comments/elw0x/allegations_regarding_openbsd_ipsec_fbi_backdo...
01:32 xelister so if you think your computer is quite secure - think again - uncle sam may be screwing you in the ass right now with such criminal activities
01:33 noagendamarket ffs
01:33 kiba you believe everything you read, xelister ?
01:33 kiba you need some mild skepticalism
01:34 xelister kiba: I beliver the developer of OpenBSD kernel. And as he said, the story is unfolding right now, we will see where it leads
01:34 midnightmagic ArtForz: interesting book; seek "Malicious Cryptography: Exposing Cryptovirology" by A. Young, M. Yung.
01:35 midnightmagic could be as simple as a keygen width reduction. couple bits might do the trick.
01:35 xelister kiba: but since we knew USA are ok with stuff, like, from killing natives, via posioning watter supply in France with LSD (resulting in few deaths too), via attacking many countries, to smear campaign against wikileaks and to war on own citizens... I think it is well within normal behaviour of this criminakls
01:35 xelister criminals
01:35 Granttt is this really any "shock", what took them so long, they announced war on internets a while ago: http://news.bbc.co.uk/2/hi/8073654.stm
01:35 noagendamarket *rages
01:35 kiba there's criminal behavior and feasialbity of doing said criminal behavior
01:36 kiba national security is such a murky concept ;)
01:36 midnightmagic feasibility of a keyspace usage reduction > small. :)
01:36 xelister kiba: paying some coder to hide a backdoor? it happens all the time even by accident, why it should be not possible to do it on purpose
01:36 noagendamarket "cyber tsar"
01:36 midnightmagic "National Security" is a weapon by which the prole is oppressed.
01:36 xelister Granttt: yeah, what that nigger is doing
01:37 kiba if you want security, abolish all gun control laws
01:37 noagendamarket xelister thats a bit much
01:37 midnightmagic xelister: yeah, now you're just batshit foaming..
01:37 xelister Granttt: what are the people thinking now? "oh yea we voted the liberal, free, internet friendly guy hehe <3... oh, no... wait..... oh."
01:37 kiba than if somebody want to invade you, they better be prepared for a long war against civilians
01:37 Granttt he's just doing his job, the president is decentralized p2p engine of the lobbyists who sponsored him ;)
01:37 xelister kiba: what do you mean?
01:37 midnightmagic perhaps trollboy has outlived his useful presence in the channel.
01:37 kiba xelister: the proliberation of arms amongst civilians....
01:37 xelister kiba: in USA guns are allowed though
01:38 noagendamarket not everywhere
01:38 kiba xelister: some people want to control who get to have guns...
01:38 midnightmagic racist trolls aren't appreciated.
01:38 xelister kiba: well I think allowing all guns and allowing much more things is good - in a sense that it makes it harder for grup of thugs (like gov) to get exclusive controll over power
01:38 kiba xelister: that's the whole point
01:39 kiba and you can't get something like a bunch of terrorists take over whole planes with a bunch of box cutter or something
01:39 xelister midnightmagic: nigger please. I have nothing against black people. But I laugh at idiots that put so called "politicall correctness" above anything else. Example: it is o.k. to kill people based on their nationality or race (in example 'sand niggers' in Iraq), but it is bad to say the N- word. Wtf is up with that.
01:40 xelister but that is just small digression from the topic of - how usa gov are dicks and can we trust then any computing system to be secure
01:40 kiba real security is not about sending an occupation force to some faraway country
01:40 midnightmagic xelister: nice pause before escalating. You are a troll. Your timing gives you away.
01:40 midnightmagic Hey.. OPS.. wtf guys?
01:40 noagendamarket fed
01:40 xelister midnightmagic: there is a magic /ignore command
01:40 kiba xelister is not a troll, just a very passionate person
01:41 xelister I mean, even hardware CPUs are being backdoored
01:41 ArtForz yep
01:41 xelister now the supposedly most secure os, openbsd is (allagedly still) backdoored since 'ever'
01:41 ArtForz at least xe, diablo and me like to rant about random crazy stuff from time to time
01:41 midnightmagic sounds trolly to me. that's deliberate antagonism.
01:41 xelister .me highfives ArtForz
01:42 xelister I think nowdays man can trust a computing platform, if he builds it from scratch, from logical gates from raw materials
01:42 xelister this is sad
01:42 noagendamarket for the 90 per cent of people who dont compile all their own shit its bad
01:43 noagendamarket thats all that matters
01:43 ArtForz well, at least obsd has more than 65536 possible rsa keys :P
01:43 xelister midnightmagic: btw if you fell strongly about problems of racial (or any other) hate, then act on that case where USA police beaten up a black girl 'because', or a Pollock wemen recently. Write your senator or soemthing
01:43 midnightmagic okay then. xelister, douchebags claim anti-PC as an umbrella for their douchebaggery. That doesn't make them any less douchebaggy.
01:43 xelister have to go now
01:43 midnightmagic Also, I'm not American.
01:44 xelister everyone should tweet/tell friends/or smth about this crap from USA (and other govs;) and about bitcoin by the way o/ bbl o/
01:44 nanotube that said... you guys might want to take the offtopic discussion to -discussion or something. :)
01:44 nanotube though i guess it's fine in absence of actual dev-related talk happening at the same time...
01:45 ArtForz this channel isn't #bitcoin-usually-ot ?
01:45 ArtForz ;)
01:46 MT`AwAy (if anyone wants to spend time reading php, the gawker/gizmodo hackers who released the user passwords to the world also included some sourcecodes)
01:48 nanotube ArtForz: heh yea, de-facto it is ;)
01:49 Zarutian xelister: that (build computer up from raw materials) or use mutually private computing on two machines http://unenumerated.blogspot.com/2007/08/mutually-private-computation.html
01:50 xelister Zarutian: seems fun
01:50 xelister Zarutian: randomized things like even say private key generator are problem though etc et
01:50 xelister but in fact this is one solution
01:50 xelister ok g2g cya
01:57 xelister btw if it didnt worked with wikileaks dotations by BTC, then perhaps #openbsd would like.. some1 should ask
02:02 kiba donation
02:07 MT`AwAy lol
02:11 noagendamarket I like that someone wants to send a satellite into space
02:12 noagendamarket it will be cool if they run a bitcoin client from there
02:12 ArtForz where else would you send a satellite?
02:12 noagendamarket haha
02:16 noagendamarket http://www.bitcoin.org/smf/index.php?topic=2282.0 i was referencing that thread
02:17 aximilation_ hey all
02:20 Auctus won't bitcoin eventually fill your hard drive with transaction history/blocks/whatever?
02:22 Lysacor Well tonight I am officially one more to blame for the difficulty going up :P
02:23 Lysacor ;;bc,calc 334000
02:23 gribble The average time to generate a block at 334000 Khps, given current difficulty of 12252.03471156 , is 1 day, 19 hours, 45 minutes, and 51 seconds
02:23 Lysacor ;;bc,estimate
02:23 gribble 13735.55418392
02:24 noagendamarket Auctus most of the transactions will be forgotten in future
02:24 ArtForz doesn't look like we'll be doing x1.4 this time
02:25 ArtForz we're already > 800 blocks into current difficulty, if rate of growth stays the same we're headed for ~x1.3
02:27 aximilation_ hmm, so if I leave it on for a couple days how much space would I be expecting to see it use?
02:27 Lysacor well at least as long as we don't get another ~4000 increase like we got last round
02:27 ArtForz which would nicely balance out the ~ x1.5 from 8078 to 12252
02:28 Lysacor agreed, at least I won't feel like I wasted money on the investment in this card
02:28 ArtForz as before we were doing pretty close to x1.4 per difficulty
02:29 Lysacor We shall see what happens in the coming days. You think there could be a significant swing?
02:29 ArtForz kinda
02:29 ArtForz looks like prices are rising again
02:30 Lysacor yep, I should have had my sell price higher on mtgox, I got a bit excited on the last price spike earlier last week
02:30 noagendamarket I think they should after all the positive publicity
02:30 ArtForz yep
02:30 Lysacor absolutely
02:30 noagendamarket the EFF just posted another article including bitcoin
02:31 kiba yeah, we know
02:31 aximilation_ I *just* started running it tonight
02:31 ArtForz which means more miners expecting a continued uptrend, which makes investing in mining equipment more likely
02:31 Lysacor welcome to the fun aximilation_ :)
02:31 midnightmagic sweet..
02:32 aximilation_ thanks :-D
02:32 aximilation_ I'm not sure what to expect with it, but my computer sits idle most offff the time, so hey why not?
02:32 noagendamarket newegg would make a bit if they sold gpus for bitcoins...
02:32 Lysacor oh heck yeah they would...
02:33 noagendamarket probably more than the people buying them lol
02:33 Lysacor aximilation_: could be worse ways to burn electricity
02:33 aximilation_ haha
02:33 ArtForz if bitcoin becomes more widespread a few people at are gonna scratch their heads why people keep buying 5970s :P
02:33 noagendamarket lol
02:33 Lysacor and then the price will go up perhaps because of demand?
02:33 Lysacor especially if there is a shortage
02:33 aximilation_ ...and say hello to a bunch of incoming connections to 8333, lolllll
02:34 ArtForz well, I hope lots of gamers are going for 6970/6990
02:34 ArtForz = more decent used 5970s on ebay
02:34 Lysacor mmmm that is true.... 500 USD is still a bit high for me :P
02:34 Lysacor even though it is 2x my Mhash...
02:34 noagendamarket what is the difference in hash rates?
02:34 aximilation_ what's this, using video cards to help crunch numbers?
02:35 ArtForz yup
02:35 Lysacor hehe GPU mining
02:35 ArtForz thing is, it doesnt look like 6970 will be good for mining
02:35 kiba noagendamarket: did ya try my http://www.soulplaying.com todo RPG?
02:35 ArtForz my calc says about 244Mhash/s
02:35 Lysacor oh really, I haven't seen the specs on it
02:35 ArtForz well, rumored specs are 1536 ALUs, 880MHz
02:35 midnightmagic the GPU is sometimes two orders of magnitude stronger than a moderately-fast CPU in mining.
02:35 ArtForz release is... today
02:35 aximilation_ oh nice
02:36 midnightmagic and it's possible to stuff four (or more, I guess) into a single system.
02:36 ArtForz well, or tommorow, depends on timezone
02:36 noagendamarket well that would increase difficulty
02:36 kiba wonders why nobody bother to try out
02:36 ArtForz afaict NDA lift is 15. 12AM EST
02:36 aximilation_ how does an AMDII x64 2.6ghz rank in the whole scheme of things?
02:36 Lysacor well, we will see who gets to do the sucker.... err beta testing :P
02:36 kiba it's a 15 days trial
02:37 ArtForz but if the leaked specs are true, a 6970 is barely faster than a 5850 for mining
02:37 Lysacor aximilation_ my wife has one... but won't let me test it on her box... but I estimate a decent amount... I think that those cpu's can do 4-way if I reacll
02:38 Lysacor recall
02:38 Lysacor the AMD Phenom II x4 right?
02:38 ArtForz not too surprising, 58xx was exceptionally ALU-heavy for a GPU
02:38 aximilation_ erm, not sure
02:38 aximilation_ AMD Athlon(tm) II X4 620 Processor
02:38 midnightmagic I can tell you what an AMD 1090T Black Edition can do..
02:38 Lysacor aaah, well it is on the lower end
02:39 ArtForz Ahtlon II is still K10 arch, right?
02:39 Lysacor I believe so
02:39 ArtForz should get close to the same hash/MHz/core as a PhenomII
02:39 aximilation_ not sure about it, I just know it runs well :-D
02:39 noagendamarket damn 5970's are all over $700 AUD
02:39 ArtForz as the miner loop should be small enough to fit in L1
02:39 ArtForz australians gets fucked when it comes to tech
02:40 midnightmagic 3.2GHz, each core using the cpuminer can do about 2.3Mhash/sec; total is about 14Mhash/sec, or (coincidentally) about as fast as a GeForce 9600GT.
02:40 noagendamarket I dont think its worth it just to mine
02:40 midnightmagic 5970 here is $500 CAD.
02:40 Lysacor anyone in the southern hemisphere from what I can tell, Chile is the same way... almost 100% markup
02:41 noagendamarket probably cost heaps in postage from the states
02:41 aximilation_ so when I run bitcoind is it automatically mining?
02:41 Lysacor midnightmagic: good lord... decent cpu hash rate indeed
02:41 ArtForz 5970 here WAS 380EUR incl. 19% VAT, now it's back up to 410
02:41 noagendamarket I blame you for pushing up demand lol
02:42 Lysacor didn't you get some ungodly amount of 5970's art?
02:42 ArtForz 24
02:42 midnightmagic Lysacor: that's with the 4way core in the cpuminer from.. hrm.. git://github.com/jgarzik/cpuminer.git
02:42 Lysacor wow... yeah... I don't wanna see that electric bill
02:42 ArtForz cancelled my order for 12 more, they pushed the shipping date out to january
02:43 Lysacor there goes the difficulty, thanks for giving me at least a week to TRY to get some generated coins! :D
02:43 ArtForz guess I made a e-tailer happy (ordered em back when they were 380 a pop)
02:43 Lysacor damn... I can't find them for less than 499 anywhere, you must have done some research
02:44 ArtForz thats 380 euros
02:44 Lysacor aaah not USD
02:44 noagendamarket I think artforz is plugged directly into a power station
02:45 noagendamarket with an extension lead lol
02:45 Lysacor ok sorry, gotta get my shit fiat currency out of my head by default...
02:45 ArtForz I should write a FAQ
02:45 noagendamarket haha
02:45 noagendamarket an Arti FAQ ?
02:45 ArtForz yup
02:45 Lysacor who needs an extension cord, I got some 8 gauge copper waiting to whip up there! :P
02:46 noagendamarket I have 3 phase power in my shed :)-
02:46 ArtForz I have my own micro cogeneration plant (aka diesel gen replacing oil burner for central heating)
02:46 noagendamarket is diesel generators efficient?
02:47 Lysacor nice, helps to keep the grid usage lower, though is the diesel fuel producing a bit less expensive energy, compared to the grid at large?
02:47 ArtForz if you use it to heat your house... yes
02:47 Lysacor true
02:47 ArtForz thats the whole idea about micro-cogen
02:47 ArtForz instead of turning oil into heat, you turn oil into heat+power, and the power into heat, too
02:47 noagendamarket move to antarctica and you could generate more
02:47 Lysacor a lot more efficient
02:47 ArtForz so you basically get free power out of the deal
02:48 ArtForz well, except for the initial investment and higher maintenance of course
02:48 Lysacor probably go from 20-30 percent efficiency into the 50-70 range?
02:48 midnightmagic ArtForz: what's the power grid there cost per kWh?
02:48 ArtForz about $0.30
02:48 Lysacor yeowch
02:48 ArtForz a modern central heating oil burner is >90% efficient, so is a micro-cogen
02:49 Lysacor very nice!
02:49 ArtForz of course only about 30% of the cogens output is electric
02:49 midnightmagic holy crap. it's $0.0875 here for tier-2 power (so, more than X kWh per month, which a farm like yours would definitely put me into)
02:49 Lysacor I wish I could 1. afford one and 2. install one in such a way that my landlord wouldn't evict me on the spot
02:50 midnightmagic and that's CAD, too..
02:50 gribble {"ticker":{"high":0.2468,"low":0.21,"vol":10188,"buy":0.2152,"sell":0.2459,"last":0.2467}}
02:50 Lysacor ;;bc,mtgox
02:50 ArtForz benefits of owning your own house ;)
02:50 ArtForz yep, canada has about the cheapest power in the world
02:51 Lysacor average here where I live is $0.10
02:51 aximilation_ funny you mention that, my workplace just relocated some web servers to canada partly due to the power reasons
02:52 midnightmagic monthly cost for one of your 1.3KW at-the-plug machines is ~$82/month..
02:52 midnightmagic ArtForz: did you order the new machines because you want to stay ahead of the influx of GPU miners?
02:52 ArtForz not really
02:52 midnightmagic you're doing it for fun aren't you
02:53 ArtForz yup, pretty much
02:53 kiba for fun and profit!
02:53 ArtForz well, is there a better reason? I like challenges :P
02:53 Lysacor imagine if you could Crossfire all those things into one big array of cards... wow...
02:53 noagendamarket lol
02:53 midnightmagic No, no better reason. :)
02:53 noagendamarket cloud server?
02:54 ArtForz hrrrm, looks like theres another option
02:54 jb55 I have been trying to compile bitcoin on ec2 gpu cluster instances with no avail
02:54 jb55 damn centos
02:54 ArtForz older FPGAs arent worth it, but xilinx spartan6 looks like it could be a winner for hash/W
02:55 Lysacor jb55:wonder how quick they would boot you off of EC2 if you managed it?
02:55 ArtForz still sucks for hash/$ though
02:55 midnightmagic I would love to see a bunch of machines pay for themselves while I do R&D on distributed computing.. it would mean I could extend out my reach.. to.. well beyond what I thought would be within my reach as a hobbiest.
02:55 kiba I make more money drawing than coding :(
02:55 ArtForz so... copacobana with spartan6 anyone?
02:55 jb55 Lysacor: I dont see why they would, that's what they're for. number crunching.
02:55 kiba nobody want to play with my wwww.soulplaying.com :(
02:56 kiba errr wwww.soulplaying.com
02:56 kiba err..damn
02:56 kiba www.soulplaying.com
02:56 noagendamarket kiba im too lazy for that lol
02:57 kiba don't play an MMO, play a real life RPG!
02:57 kiba play your very soul!
02:57 Lysacor so I am not selling my soul for a couple of trinkets right? :P
02:57 Lysacor not that I had one to begin with :P
02:57 kiba no, you're playing as yourself
02:57 midnightmagic well the virtex almost certainly aren't worth it.
02:57 kiba in improving your life skill
02:58 kiba it's only like 3 bucks a month...
02:58 ArtForz 120 spartan6-sx45 should be able to get about 4.5Ghash/s using ~400W
02:59 ArtForz beats 5970s by about a factor of 6 on hash/W
02:59 jb55 are there FPGA hobby kits? :D
02:59 ArtForz yup
02:59 ArtForz and horribly loses on hash/$
02:59 ArtForz the chips alone are ~$6.5k
02:59 aximilation_ kiba do you run your own server there?
03:00 midnightmagic you can get cheap spartan 6..!
03:00 ArtForz add custom PCBs, PSU, custom case ... 9 grand
03:00 jb55 ouch
03:00 ArtForz well, it's also about as fast as 8 5970s
03:00 Lysacor whew... a bit too rich for me
03:00 kiba run what server?
03:01 kiba mining is just a side income
03:01 ArtForz so roughly half the hash/$ of 5970s
03:01 ArtForz but 5x better hash/W
03:01 aximilation_ soulplaying
03:01 kiba does that mean you will sell 5970s for bitcoins?
03:01 ArtForz but at least you dont need to order crazy amounts of em to get a decent price
03:01 kiba aximilation_: no, I used heroku
03:01 midnightmagic $14,280 for 120 spartan-6 XA6SLX75-2FGG484I from digikey. what part number are you looking at art?
03:02 aximilation_ ah, I was going to say you should really catch the www and direct it to the non-www
03:02 ArtForz you're checking out the -75s
03:02 ArtForz XC6SLX45-2CSG324C
03:02 kiba don't you mean non-www to www?
03:02 ArtForz digikey 122-1673-ND
03:03 aximilation_ yea, or that
03:03 Lysacor thinking about the mtgox market... with all of those standing ASK orders for .32+ in 1000 coin blocks... that might potentially stunt the market
03:03 Lysacor but, not knowing the historical market depth, it is an uneducated opinion at best
03:03 midnightmagic that's half the onboard logic units.. but cheaper overall. you always seem to find the maximum economic wins. LOL how long have you been looking for fpga anyway? :)
03:03 ArtForz not too long
03:04 ArtForz but I was looking at FPGA to prototype my ASIC design in hardware
03:04 ArtForz turns out my VHDL synthesizes to something with decent performance on virtex5 and spartan6
03:04 Lysacor kiba: next paycheck if I am looking in a good position, I may try your site, couldn't hurt
03:05 midnightmagic can I be your disciple?
03:06 Lysacor Art, be careful, looks like you are inadvertantly starting your own religion here :P
03:06 EvanR i just heard about bitcoin today. how long has this operation been going on?
03:06 kiba operation? what operation?
03:06 EvanR bitcoin
03:06 kiba bitcoin is not an operation
03:07 midnightmagic it's a religion!
03:07 EvanR lol
03:07 EvanR or is it dead, in the final stages and i just came in at the end
03:07 mndrix_ EvanR: first block was in Jan 2009, I think: http://blockexplorer.com/b/0
03:07 ArtForz it's a movement!
03:07 Lysacor From what I know, it has been going on for some time
03:07 Lysacor nowhere near dead
03:07 Lysacor very much growing
03:07 kiba it's been growing
03:07 kiba December is going to smash record!
03:08 midnightmagic And not the kind that you flush!
03:08 kiba oh wait, we already did
03:08 EvanR i tried to invent this a few months ago
03:08 ArtForz merely pining for the fjords *ducks*
03:08 kiba but we will smash more record!
03:08 EvanR when reading about digital signatures
03:08 EvanR i didnt get anywhere
03:08 kiba not suprising
03:08 EvanR ive been looking for a place to store my money
03:08 EvanR i dont trust banks
03:08 ArtForz the real genius of bitcoin is the distributed timestamping system
03:09 kiba oh yeah
03:09 midnightmagic not really a great economy to store large volumes of cash in.. :)
03:09 kiba Satoshi is really a girl
03:09 kiba and her name is not Satoshi
03:09 midnightmagic Shhh.. don't tell him all the secrets right away.
03:09 ArtForz and using mining/transaction fees as an incentive to keep enough CPU power on it
03:10 jb55 EvanR: same, right now I have my wallet inside of a truecrypt volume sitting in my dropbox :D
03:10 EvanR lol
03:10 midnightmagic First he has to punch his fingers through the gravel for six months!
03:10 Lysacor No, no, it is walk through glass covered in margarita salt...
03:10 EvanR i looked at the server, looks like an iphone app waiting to happen
03:10 midnightmagic Err.. I mean mine fruitlessly on his GPU for six months!
03:10 Lysacor broken glass
03:11 kiba what server, EvanR?
03:11 EvanR bitcoind
03:11 Lysacor possible, but I doubt the carriers would like 8333 traffic trickling into the network :P
03:11 midnightmagic maybe as a controller via the JSON interface! that would be kind of neat. just make sure that other people with the app can move bitcoins to one another without manually typing in long strings of bitcoin addresses and you're good!
03:11 EvanR Lysacor: it would be port 80
03:12 EvanR er
03:12 EvanR https whatever it is
03:12 Lysacor 443
03:12 Lysacor :)
03:12 EvanR midnightmagic: nicknames to the rescue?
03:12 aximilation_ EvanR: I just set up bitcoind about half an hour or so ago myself
03:13 kiba newbies.
03:13 EvanR i was about to, but realized i didnt have a dedicated server
03:13 EvanR and the server i was on wasnt really mine
03:13 EvanR so i stopped
03:13 aximilation_ run it on a home computer :-D
03:13 EvanR i actually dont have interne
03:13 EvanR im stealing wireless
03:13 aximilation_ that works
03:13 kiba I need to do something about backup and encrypting my wallet
03:13 kiba really paranoid
03:13 EvanR bitcoin still works
03:14 Lysacor you are "borrowing", stealing indicates malicious intent :P
03:14 aximilation_ might be more difficult to forward 8333, but hey
03:14 Lysacor borrowing without intent of return...
03:14 aximilation_ "using"
03:14 EvanR stealing indicates ironic abuse of loaded words
03:14 EvanR sharing!
03:14 aximilation_ neither borrowing nor stealing could apply, as there is no way you could give the internet back
03:14 Lysacor nice!
03:14 ArtForz how can you steal wireless?
03:14 kiba ArtForz: you torrent through it
03:15 kiba depriving the owner of his bandwidth!
03:15 ArtForz aka "hey, I didn't ask for my neighbor to broadcast his radio waves all over my place"
03:15 Lysacor yeah, saturate the pipe... that is where QoS comes in handy :P
03:15 aximilation_ it's really not much different than "stealing" music from an open air concert by listening from outside the grounds
03:15 Lysacor true
03:15 EvanR so am i reading this dashboard correctly, 'we are on block 93691' ?
03:15 ArtForz ;;bc,blocks
03:15 gribble 97613
03:15 EvanR i am out of date?
03:15 Lysacor actually, you are a few blocks behind, a bit more to download
03:15 EvanR or this isnt a global number
03:15 ArtForz no, it's a global number
03:16 Lysacor nope, globally it is 97613
03:16 Lysacor every client shares the same block chain database
03:16 kiba grow, bitcoin, grow!
03:16 EvanR is 100000 a special milestone or something?
03:16 Lysacor it is shared between clients
03:16 kiba no
03:16 ArtForz if you don't want people "stealing" your WiFi, turn on encryption or get a lot of tin foil.
03:16 EvanR ok
03:16 aximilation_ "Unauthorized Use"
03:16 Lysacor tinfoil hats!!
03:17 ArtForz well, *someone* set it up as a free-for-all
03:17 EvanR also ironic, the guys password is "money money"
03:17 ArtForz lol
03:17 aximilation_ password for what?
03:17 EvanR wireless
03:17 aximilation_ how'd you come across the password?
03:17 EvanR not hard to guess
03:17 aximilation_ lol
03:17 kiba he love money?
03:18 ArtForz btw, huge fuckup of a german ISP, their router/APs have WPA2 turned on by default, turns out the default WPA2 key contains a whopping 24 bits of entropy
03:18 aximilation_ in that case you're in a slightly "risier" position as it's not completely open to the public
03:18 EvanR he told me the password
03:18 aximilation_ oh
03:18 ArtForz well, then its not stealing now, is it?
03:18 aximilation_ nvm then, telling is permission then
03:18 EvanR never was
03:18 aximilation_ or close enough
03:19 Lysacor backtrack is a wonderful tool...
03:19 EvanR it says 1khash/s
03:19 aximilation_ you know this whole discussion started because you said you were stealing wireless...
03:19 Lysacor great for wifi key discovery and breaking
03:19 ArtForz btw, 24dBi parabolics are fun
03:19 Lysacor and attacking other people's AP's
03:20 Lysacor what range you manage to get on it Art?
03:20 ArtForz we got about 5 miles out of it with direct LOS
03:20 EvanR aximilation_: not my fault
03:20 EvanR i think i got all the blocks
03:20 Lysacor very nice!
03:20 EvanR 97614
03:21 Lysacor yep, you are caught up now EvanR
03:21 EvanR 474 khash/s
03:21 ArtForz and the transmitters turned down to lowest output
03:21 ArtForz stupid ETSI EIRP rules
03:21 EvanR its the code of the radio operator, use lowest power necessary to carry out communication ;)
03:22 Lysacor true, but ETSI... FCC... they all over-regulate the spectrum to some degree...
03:22 EvanR ignore numbers stations and best of hip hop and r&b FM stations
03:22 ArtForz yeah, but seriously, 1W EIRP?
03:23 Lysacor imagine if you could go 50 percent higher, what the results would be
03:23 EvanR what is this generate coins this, does it randomly give you 1 coin? or some other amount? how often?
03:23 Lysacor without risk of fines...
03:23 EvanR this->thing
03:23 ArtForz 50 percent? why not an order of magnitude
03:23 Lysacor mmmm true
03:24 EvanR 10W is insane
03:24 ArtForz 10W EIRP on a 23dBi isn't exactly a lot of output
03:24 ArtForz take line and connector losses into account and you're looking at 100mW tx output
03:24 Lysacor so, bitcoin generates coins when you solve a given hash of a block, as time goes on the number of coins earned by solving blocks are less and less, (bitcoin.org details it all)
03:25 Lysacor as the number of blocks in the collective block chain increases
03:25 ArtForz yep, first halving should be late 2012/early 2013
03:25 Lysacor right now you get 50 per solved block
03:25 EvanR oh
03:25 Lysacor BUT, you can join a pooled mining effort
03:26 Lysacor http://www.bitcoin.org/smf/index.php?topic=2027.0
03:26 EvanR all nodes are solving simultaneously, and whoever gets there first gets the cash?
03:26 EvanR then you start over?
03:26 Lysacor yep
03:26 EvanR cant they solve in parallel? or would that be defeating the purpose somehow
03:27 Lysacor the pooled mining effort combines the hashing power of multiple systems, to increase the likelihood of the group solving the block. As that one is setup, you get a number of coins (and they can be in decimal values) based on the amount of hash work contributed to the pool
03:27 Lysacor the more you do compared to the rest, the larger your share of the block solved
03:28 Lysacor the pooled mining effort has solved two blocks thus far
03:28 MT`AwAy and your bitcoin client will throw away as soon as it can any sub-cent coin you've earned
03:28 EvanR thats a question i was having, so 0.30 is a valid number of coins?
03:28 Lysacor exactly
03:28 Lysacor it certainly is
03:28 Lysacor there are other ways to get bitcoins
03:28 EvanR i think its also valid in json, but in a javascript engine it wont be represented as that
03:28 Lysacor namely through trade, through a site like bitfaucet
03:28 doublec MT`AwAy, the bitcoin client doesn't throw away sub-cent coins
03:28 Lysacor etc... etc...
03:29 ArtForz doublec: it does
03:29 MT`AwAy doublec: it sure does, sends them as "fee"
03:29 aximilation_ I got some from bitfaucet :-D
03:29 doublec So if I have 0.001 sitting in my account it will vanish without me doing anything?
03:30 MT`AwAy doublec: if you send coins to someone, the 0.001 part will be added to "in" automatically, but not to "out"
03:30 doublec why does it do that?
03:30 MT`AwAy so anyone who takes your transaction in and solves the block will get your 0.001
03:30 EvanR lol free bitcoins
03:30 MT`AwAy doublec: ask Satoshi, but I think it may have to do with the inital sub-cent transaction floods?
03:31 doublec so as long as I never send anything in my wallet then the subcent generated transactions can add up?
03:31 MT`AwAy doublec: yep
03:31 Lysacor www.mtgox.com is one of a few bitcoin investment sites
03:31 doublec That's more of an argument that puddinpop should change the server to round to 0.01
03:31 ArtForz well, if your tx had a sub-cent output, it'd cost 0.01 in f ees
03:31 MT`AwAy and once you reach a cent, it'll stay
03:31 ArtForz whats better? paying < 0.01 or paying 0.01 ?
03:32 MT`AwAy ArtForz: he can just keep accumulating sub cents until it gets to 0.01
03:32 EvanR sub cent makes sense
03:32 MT`AwAy or until someone modifies the client to not throw away subcents
03:32 ArtForz well, if your client uses it as a input, it has reason to
03:32 EvanR how hard is it to make your own client?
03:33 MT`AwAy EvanR: I'm doing it, and it's not that simple
03:33 ArtForz if you have 0.075 and send 0.05 you keep the 0.025
03:33 MT`AwAy ArtForz: actually, you don't
03:33 MT`AwAy if you have 0.075 and send 0.05, you'll keep 0.02
03:33 ArtForz err, the throw-away-subcent code only kicks in if a output is < 0.01
03:33 EvanR i got 0.05 coins!
03:33 nanotube looks like there's need for a patch to undo the throwing away of subcent bitcoins...
03:33 MT`AwAy and 0.005 are added as "fee" to the transaction
03:34 aximilation_ is this the gui client, or does it apply to bitcoind as well?
03:34 aximilation_ since my balance shows 0.05000000
03:35 Lysacor brb gonna put my computer on a kill-a-watt meter and see what the damage to my electric bill is gonna be...
03:35 EvanR i got coins from 'someone' it says unconfirmed. im 'pretty sure' its bitfaucet. how do i tell the client to identify that address as that?
03:36 MT`AwAy found one
03:36 MT`AwAy http://blockexplorer.com/tx/19daf081d3139e8fa11a2ae6467098312f1e86fe3a9e9e8b81a26e68b0f4f145 <- 50 btc sent, the input also includes subcents
03:36 EvanR oh thats not what unconfirmed means
03:36 ArtForz yes
03:36 MT`AwAy EvanR: you need to wait, the transaction will get confirmed
03:36 ArtForz and the 2nd output would'Ve been < 0.01
03:37 MT`AwAy the bitcoin client could have just kept the sub-cent part on the initial wallet
03:37 ArtForz if he had sent 45, he'd have gotten 5.0049... in change back
03:37 MT`AwAy since it doesn't systematically empty addresses
03:38 ArtForz no it couldnt have
03:38 ArtForz that was from a 50.0049... generation
03:38 ArtForz if it only has that 1 tx, and you want to send 50, whats it suppsoed to do?
03:38 ArtForz a) send 50, send 0.0049 back to yourself, needs a 0.01 fee
03:39 MT`AwAy just send 50.00000000, and let the 0.0049... part on the address
03:39 ArtForz b) send 50, throw away the 0.0049 as fee
03:39 MT`AwAy s/let/keep/
03:39 ArtForz it's a SINGLE TRANSACTION
03:39 ArtForz you can't KEEP part of an output
03:39 ArtForz you have to use the whole output
03:39 MT`AwAy you can keep part of the input on the address
03:39 MT`AwAy nothing requires the "in" address to be emptied each time
03:39 EvanR what does 'throw away' mean, lost to oblivion? or sender keeps it
03:39 ArtForz ARGH
03:39 ArtForz the input was this: http://blockexplorer.com/tx/7ff761d4749f64c41d1ba7018841b863a0f1b56fe1d62a8369ed452216c421ab#o0
03:39 MT`AwAy EvanR: whoever solves the block gets it
03:40 ArtForz SINGLE OUTPUT, 50.0049...
03:40 ArtForz user requests a send of 50 to some address
03:40 EvanR thats strange
03:40 ArtForz so whats his client supposed to do then?
03:40 MT`AwAy ArtForz: what I say is to /not/ inclue the 0.0049.. part in the input
03:40 MT`AwAy include*
03:40 ArtForz you can't do that
03:40 MT`AwAy you can
03:41 ArtForz no you can't
03:41 ArtForz once a output is used, it's marked as spent
03:41 ArtForz read the fine code
03:41 nanotube ArtForz: so if even one of the outputs of a single tx is <0.01, the whole tx requires a fee?
03:41 ArtForz yep
03:41 MT`AwAy ArtForz: I'm talking about the input
03:42 MT`AwAy if you got 500 bitcoins on address X, you can either put the whole thing as input, or only a part
03:42 EvanR bitfaucet is funny. TANSTAAFL was almost violated. until i realized you cant get lunch on 0.05 coins
03:42 nanotube ArtForz: i guess in that case it's fine. since it doesn't make sense to spend .01 in order to save <0.1
03:42 MT`AwAy the remaining balance stays on X
03:42 nanotube <.01 i mean
03:42 nanotube EvanR: haha yea
03:42 ArtForz the INPUT to the 50+0.0049fee TX was a SINGLE 50.0049 OUTPUT
03:42 MT`AwAy oops
03:43 ArtForz if you have multiple outputs to the same pubkey available, you can obviously use only one of them
03:43 MT`AwAy forgot input reference tx
03:43 EvanR how long does it take to confirm?
03:43 MT`AwAy EvanR: ~1 hour
03:43 EvanR >_<
03:44 ArtForz one or more I mean
03:44 EvanR it says 3/unconfirmed now
03:44 MT`AwAy but you can use your coins with only one confirmation
03:44 MT`AwAy EvanR: you can already use the coins then
03:44 EvanR what does the number mean
03:44 MT`AwAy EvanR: it's the number of blocks after your transaction
03:44 ArtForz and iirc the current client code only throws away < 0.01 amounts if it'd otherwise have to send them back to itself as change, incurring the 0.01 fee
03:44 MT`AwAy the more blocks there are, the more you know the transaction is legit
03:45 ArtForz so you can have a tx of 50.0049 -> 45 + 5.0049 change
03:45 EvanR is there an arbitrary threshold where it 'gives up' and says confirmed
03:45 ArtForz I dont think it's smart enough to combine multiple sub-cent containign inputs to make a whole cent
03:45 aximilation_ anyone work with the market like mtgox?
03:46 aximilation_ or use it to buy/sell?
03:46 MT`AwAy ArtForz: I guess it's still better to keep subcent until bitcoin becomes smart enough :)
03:46 ArtForz so if you have 50.006 and 50.005 and send 50, it uses one of them and throws away the 0.005 or 6
03:46 aximilation_ or do you do most of your saving my mining?
03:46 EvanR what happens if you 'open' your wallet on multiple computers at once
03:46 aximilation_ s/my/by
03:46 ArtForz instead of doing (50.005 + 50.006) -> 50 + 50.011 change
03:46 MT`AwAy EvanR: you see your balance multiple times, but can use it only once
03:47 EvanR then what
03:47 MT`AwAy EvanR: then you can't send more coins
03:47 EvanR on either?
03:47 MT`AwAy because in reality you don't have more
03:48 EvanR will it segfault, signal alert ERROR, or explain thoroughly the problem ;)
03:48 MT`AwAy I think the transaction will just disappear or never get confirmed, I'm not sure (didn't look into that yet)
03:49 MT`AwAy one thing sure is the fact the network will not accept that
03:49 ArtForz the balance on the other nodes shoudl disappear when they see the tx in a block
03:49 ArtForz if they try to send a tx before, network will just drop it as a double.-spend
03:49 EvanR really? thats cool
03:50 annodomini So I've solved my first block. Now what to spend my ?50 on?
03:50 Lysacor ok, so my wallet won't be burning, very nice! there are plenty of places to go :P
03:50 EvanR when i got the bitfauct coins, it changed my address. im confused
03:50 MT`AwAy annodomini: you can send sms on https://smsz.net/ for example :D
03:50 EvanR now i have two receiving addresses
03:50 MT`AwAy EvanR: you can have as many addresses as you want
03:51 Lysacor your address book allows you to create new addresses, and your address book let's you choose what address you want to receive on
03:51 EvanR are they all for one balance?
03:51 Lysacor it allows you to be anonymous
03:51 MT`AwAy annodomini: you can also donate for the EFF
03:51 MT`AwAy EvanR: yes
03:51 EvanR ok
03:51 EvanR but i can also reuse addresses
03:51 nanotube ArtForz: well, sounds relatively reasonable.
03:51 MT`AwAy EvanR: yes, but not reusing addresses is better
03:51 EvanR why?
03:51 annodomini MT`AwAy: True. Just donated to them in $ a couple days ago, and might again tonight via the Humble Indie Bundle.
03:51 MT`AwAy EvanR: it protects your privacy
03:51 EvanR hmm.
03:52 EvanR yes
03:52 EvanR but
03:52 MT`AwAy and whoever's giving bitcoins to you's privacy too
03:52 nanotube EvanR: there's a thread on the forum about 'pros and cons of reusing addresses'. read it.
03:52 EvanR ok
03:52 MT`AwAy also you can create addresses specifically for something (for example on my site, each order gets its own bitcoin address so when people pay, I know which order they paid for)
03:53 EvanR seems like id lose track without labels
03:54 EvanR i guess i could name each one as they are used
03:55 MT`AwAy I guess when you generate coins you end using one address per generated block too
03:55 EvanR when address?
03:55 EvanR erm
03:55 EvanR which address
03:56 EvanR the one in the box?
03:56 ArtForz extra credit for anyone who got the Titan AE reference
03:57 nanotube not me... no extra credit for nanotube :(
03:58 EvanR is there a mastercard/paypal blessed website where people can send or donate money to someones bitcoin ?
03:58 nanotube MT`AwAy: yes, every block gen has an address in it, which by default is a new unused address. (though it doesn't have to be)
03:58 nanotube EvanR: what does mastercard have to do with donating bitcoins?
03:58 EvanR most people dont have bitcoins to send or donate
03:59 EvanR they have usd or euros or something
03:59 noagendamarket bitcoingateway for credit cards
03:59 nanotube EvanR: --^ bitcoingateway.com you can use cc to buy btc
03:59 nanotube EvanR: or you can deposit to mtgox.com via bank wire....
04:00 nanotube or you can trade for paypal and other various and sundry things on #bitcoin-otc
04:00 EvanR otc sounds more like it
04:00 EvanR hmm
04:01 nanotube well, join the channel, and have fun. :)
04:01 EvanR so someone paying with bitcoins must first set it up and exchange for it first
04:01 MT`AwAy oh, btc is at 0.247 on mtgox :o
04:01 EvanR first
04:01 gribble {"ticker":{"high":0.2468,"low":0.21,"vol":10149,"buy":0.2152,"sell":0.2459,"last":0.2467}}
04:01 nanotube ;;bc,mtgox
04:01 EvanR what is "vol" ?
04:01 nanotube MT`AwAy: yea looks like someone bought some.
04:01 nanotube volume
04:01 EvanR whats volume
04:01 nanotube last 24 hours
04:01 nanotube how many bitcoins were exchanged on mtgox
04:01 EvanR ah
04:01 EvanR not even google could explain that
04:01 EvanR too simple
04:02 nanotube heh... well it could be either volume or volatility
04:02 nanotube and the number is way too large to be volatility
04:02 nanotube so it must be volume. :)
04:02 nanotube so you /could/ have guessed. :P
04:02 MT`AwAy only people used to markets will know what a normal volatility is
04:03 MT`AwAy :p
04:03 EvanR heres whats funny, digital data in principle can be copied exactly and be reproduced indefinitely right? yet storing money on a hard drive seems orders of magnitude more risky :S
04:03 nanotube well... or people who know what a standard deviation for numbers in the range of .22 looks like :P
04:03 nanotube EvanR: how so? just make backups.
04:03 MT`AwAy so volatility is stddev
04:03 nanotube EvanR: after all... your bank stores money on their hard drives. :)
04:03 EvanR you dont make backups of your wallet?
04:04 noagendamarket the fed prints money wsith a button
04:04 noagendamarket lol
04:04 EvanR no!!!
04:04 nanotube EvanR: i mean, when you store money on the hd, you make backups, so you don't lose it if your hd goes boom.
04:04 nanotube noagendamarket: haha
04:05 EvanR yes
04:05 nanotube EvanR: it is in fact a very smart move. as long as you encrypt your wallet first. :)
04:06 EvanR ah
04:06 noagendamarket you can email it to me and Ill store it for you lol
04:06 noagendamarket :)-
04:06 EvanR ok!
04:06 MT`AwAy xD
04:06 EvanR exchange rate around 0.250, does that mean a bitcoin is about a quarter USD or the other way around
04:07 MT`AwAy 1 BTC ~= 0.25 USD
04:07 MT`AwAy right now
04:07 MT`AwAy tommorow might be 1 BTC = 0.01 USD, you can't tell :p
04:07 EvanR haha
04:08 EvanR you can tell that from a volume of 10000 ?
04:08 MT`AwAy EvanR: there are too many unknowns
04:08 EvanR sounds like room for speculation!
04:08 MT`AwAy if someone finds a problem in bitcoin and proves that the whole concept doesn't hold, btc will suddently have no value at all
04:09 nanotube or, if someone with deep pockets decides to diversify into bitcoins and puts like 20k usd in... it may be 50c/btc tomorrow.
04:09 EvanR is it possible to buy that many bitcoins?
04:10 MT`AwAy EvanR: probably going to take a bit of time
04:10 nanotube EvanR: yes... see the outstanding orders on mtgox
04:10 EvanR ill have to checkout thissite out extensively
04:10 nanotube EvanR: go to bitcoincharts.com - it has a nice display of the open order book
04:10 nanotube if you're willing to pay up to 50c per btc, you can buy >70 thousand btc.
04:11 nanotube (and that's not counting the dark pool orders)
04:11 EvanR but theres only like 1 million total right now?
04:12 EvanR youd own a tenth of them ;)
04:12 EvanR should i be buying low? xD
04:12 ArtForz more like 5M total
04:13 noagendamarket someone is selling a house for btc
04:13 annodomini 4.88 M according to http://www.bitcoinwatch.com/
04:13 EvanR damn theres a lot of bitcoin*.foos
04:14 kiba look like the price for bitcoin is finally going up
04:14 annodomini It seems like the thing to do these days; take internet business idea, add "bitcoin" to the beginning ... profit!
04:15 EvanR annodomini: and thats why the price is going up
04:15 sgornick ArtForz: I think EvanR was referring to $1 million (US) now.
04:15 kiba 1.2 million dollars
04:15 EvanR today was a special day, i think bitcoin somehow got publicity or something
04:15 kiba not a special day
04:15 kiba but a special month
04:16 ArtForz oh
04:16 kiba we got on Wikipedia, EFF promoted us, We got Wikileak and bitcoin linked
04:16 EvanR that would suggest independent parties decided 'the concept' was pretty good
04:17 kiba we're moving out of the ignorance stage
04:17 sgornick EvanR: But lets say you were one of those learned about it because of Wikipedia, Wikileak, EFF, PC World, etc. .... how would you, three or four days later, come into having Bitcoin in your wallet?
04:17 kiba to violent opposition
04:17 kiba once we complete violent opposite
04:17 kiba then it's acceptance
04:17 EvanR sgornick: too late i already do!
04:17 EvanR 0.05 ;)
04:17 sgornick (s) plural
04:17 EvanR i guess continue to generate blocks
04:18 EvanR or become inspired and start a .com
04:18 sgornick Got GPUs?
04:18 Diablo-D3 http://www.engadget.com/2010/12/15/amd-radeon-hd-6970-and-hd-6950-launch-assault-on-enthusiast-gami/
04:18 Diablo-D3 official reviews are out
04:19 ArtForz SHINY!
04:20 Diablo-D3 http://www.hardocp.com/article/2010/12/14/amd_radeon_hd_6970_6950_video_card_review/8
04:20 Diablo-D3 fuckers need to learn to do math
04:20 ArtForz 1536SP @ 880MHz, useless for mining
04:20 EvanR how does a market work, i never understood it. we set our own prices?
04:20 Diablo-D3 if they know the total system wattage is 190, SUBTRACT IT
04:20 nanotube sgornick: you buy some on -otc or mtgox or bitcoingateway
04:20 Diablo-D3 6970 uses 238 watts max
04:21 Diablo-D3 slightly more than the 5870
04:21 ArtForz 6970 needs more power than 5870, barely faster than a 5850
04:21 nanotube EvanR: same way any market works. there's a range of buy orders, and a range of sell orders... when they come together, trading occurs.
04:21 Diablo-D3 but apparently rapes it on 3D
04:21 Diablo-D3 LOL 12 idle watts
04:21 EvanR nanotube: occurs?
04:21 Diablo-D3 jesus
04:21 ArtForz still FAIL for mining
04:21 EvanR nanotube: what i dont understand is who is deciding what
04:22 ArtForz and seems to run hot as hell
04:22 Diablo-D3 yuck, full load reaches 89c
04:22 nanotube EvanR: simple case: say i want to buy 100 bitcoins, and i'm willing to pay .20 usd/btc. someone else is looking to sell, and is willing to sell at .25/btc
04:22 nanotube EvanR: if there's nothing else happening, then no trading occurs.
04:22 ArtForz I bet the fan never goes >60% on auto
04:23 EvanR nanotube: ok, then what?
04:23 nanotube EvanR: now, some other guy comes in, and he really wantsn some btc... so he's willing to buy at .25. so he comes in and snaps up some of the seller's coins at .25/btc
04:23 nanotube EvanR: and voila, a trade has occurred. it's just like when you go to a farmer's market and want to buy some tomatoes. there are guys selling... at various price points...
04:23 ArtForz wait a sec
04:23 ArtForz the slide changed
04:23 EvanR so its like ham radio, people have to agree on a frequency or they cant hear each other
04:23 ArtForz we got 4 32-bit adds per clock again
04:24 nanotube EvanR: you go around, and if you really want your tomatoes, you buy from one of the vendors. if you think they're all to expensive, you haggle until you agree on a price, or walk away.
04:24 Diablo-D3 ArtForz: so we're back in business?
04:24 sgornick > #-otc? Assuming the person has registered their nickname weeks ago, which is the prerequisite to place an order.
04:24 ArtForz kinda
04:24 ArtForz should get 5970 about == 5870 for mining
04:24 Diablo-D3 you mean 6970
04:24 ArtForz yea
04:24 ArtForz 6970
04:25 nanotube sgornick: well, to place it officially on the book, yes. but you can also just shout out to channel. willing sellers may verify your identity, and sell to you (possibly at a bit of a risk premium)
04:25 EvanR nanotube: so there might be several 'prices' where trades are occuring, and if the people paying higher know about all of them, they will all go to the lowest?
04:25 ArtForz and VLIW4 should get us a bit better VLIW usage
04:25 ArtForz = might end up 5% faster than 5870
04:26 nanotube EvanR: yes, there may be some price differences between the various markets, depending on costs of entry, counterparty risk, etc.
04:26 Diablo-D3 and uses about 5% more watts than a 5870
04:26 nanotube EvanR: but say in case of "the mtgox market"... trading only occurs inside the bid/ask spread.
04:26 ArtForz yep
04:26 Diablo-D3 ArtForz: and costs about 5% more
04:26 EvanR nanotube: so at a single market, there is only one price?
04:27 ArtForz but it means 6990 should end up roughly == 5970
04:27 Diablo-D3 I wonder where they were going with this
04:27 ArtForz at least we wont have to go hunting for remaining stock of 58xxs
04:27 Diablo-D3 except for the vastly improved tess
04:27 Diablo-D3 whats the up side?
04:27 nanotube EvanR: assuming uniform goods (like bitcoins), yes. in case of tomatoes, no, because someone might sell better quality tomatoes than someone else. :)
04:27 EvanR currency in general is uniform?
04:27 ArtForz I have to check detailed specs, but I suspect they also beefed up ROP and TEX units
04:28 EvanR im going to the bitcoin-otc channel to see how this works
04:28 Keefe but how likely is it that the price of 6990 will be <$500?
04:28 ArtForz = 58xx was ALU heavy
04:28 Diablo-D3 ArtForz: yeah, but it doesnt seem to be improving fps
04:28 Diablo-D3 Keefe: it'll cost as much as the 5970
04:28 Keefe about as much as the 5970 did a few months ago? or now?
04:28 Diablo-D3 Keefe: the 6970 costs as much as a 5870, the 6950 costs as much as a 5850
04:29 Diablo-D3 and the 68xx is really pushing the price down
04:29 ArtForz because 68xx is the new 57xx
04:29 Keefe i'd say a 5970 can be bought for $400 if one is patient
04:29 Diablo-D3 well no
04:29 Diablo-D3 68xx is the new 58xx
04:29 Diablo-D3 same speed, much lower price
04:30 Diablo-D3 and less watts, and smaller physical die size
04:30 ArtForz 6970 is maybe 10% faster than 5870
04:30 ArtForz 6870 is a LOT slower
04:30 Diablo-D3 not on 3D it isnt
04:30 Diablo-D3 the question is
04:30 da2ce7 well for generations it counts.
04:30 Keefe 5870 is their top single chip in the 5xxx series. 6970 is the top single chip in the 6xxx series, right?
04:30 ArtForz yes it is, 6870 is ~5850
04:30 ArtForz yep
04:30 nanotube EvanR: yes, currency, stocks, bonds... all uniform, and all usually have "one price" at any given moment in time.
04:30 Diablo-D3 if the 69xx doesnt significantly beat 58xx
