109 2011-01-11 03:49:33 <da2ce7> or just a AMD cpu with a 2xSHA256/clock dedicated logic... it would only be 3M transitors. (what are they now? 975Million or something)
110 2011-01-11 03:52:48 <luke-jr> why AMD only? XD
111 2011-01-11 03:53:07 <luke-jr> are proof-of-works only SHA256s?
112 2011-01-11 03:55:54 <kartofeln> I think so.. sha256(sha256(old junk + nounce)) < somevalue. that's the whole proof of work I believe.

249 2011-01-11 13:14:35 <Ivy> hi
250 2011-01-11 13:14:55 <Ivy> i posted a bitcoin image onmy FB
251 2011-01-11 13:15:06 <Ivy> and a friend is telling me it's illegal
252 2011-01-11 13:15:17 <Ivy> I answered with "what's illegal"
253 2011-01-11 13:15:32 <Ivy> He goes... "it's not a legal tender... they'll come and get you"
254 2011-01-11 13:16:34 <Ivy> Question : can you send a link or any legal backing that I can forward? People will be reading that dialog.. and I want to show something legit... even though I'm in search of it my self... HELP
255 2011-01-11 13:17:38 <davout> Ivy: he's wrong, also burden of proof is on him
256 2011-01-11 13:18:18 <Ivy> well I'm about to tell him one can buy it sell it on the market (where's the link for that) or just convert it into dollars
257 2011-01-11 13:18:33 <davout> the link for what ?
258 2011-01-11 13:18:36 <davout> an exchange place ?
259 2011-01-11 13:18:40 <Ivy> but I'm still looking for a back up links/sites / and legal info that talks about private money ...
260 2011-01-11 13:19:12 <Ivy> Well yeah... I know the value of a Bitcoin was 6cents and then went to 50c and then back to 6c
261 2011-01-11 13:19:35 <Ivy> but I don't know yet where exactly you can buy it or sell it...
262 2011-01-11 13:20:03 <davout> http://mises.org/Community/forums/t/4682.aspx
263 2011-01-11 13:20:08 <davout> US or Europe ?
264 2011-01-11 13:20:20 <davout> if you're in the US go for mtgox.com
265 2011-01-11 13:20:26 <davout> else go to ibtcoin-central.net
266 2011-01-11 13:20:30 <davout> bitcoin-central.net*
267 2011-01-11 13:20:43 <Ivy> oh right...
268 2011-01-11 13:20:45 <Ivy> tnx
269 2011-01-11 13:20:47 <Ivy> btw
270 2011-01-11 13:21:14 <Ivy> would it be correct to say that this is international currency .... or is electronic currency better?
271 2011-01-11 13:21:26 <arcatan> you friend is probably right in the sense that bitcoin is not a legal tender the same way as foreign currencies aren't
272 2011-01-11 13:21:46 <davout> yep
273 2011-01-11 13:21:48 <Ivy> yeah ... so what do I call the bitcoin- commodity ?
274 2011-01-11 13:21:54 <davout> not being legal tender does not mean illegal
275 2011-01-11 13:21:59 <Ivy> It's not really a commodity - it is virtual...
276 2011-01-11 13:22:01 <davout> you can call it a currency
277 2011-01-11 13:22:22 <davout> computing power can be a commodity, it can be used to perform tasks
278 2011-01-11 13:22:38 <davout> the fact that its virtual is irrelevant
279 2011-01-11 13:23:05 <Ivy> ok so what do I say to his 'scare off concern'
280 2011-01-11 13:23:06 <Ivy> ?
281 2011-01-11 13:23:26 <davout> "don't be scared baby"
282 2011-01-11 13:23:34 <Ivy> heheheh
283 2011-01-11 13:23:37 <davout> there isn't anything to be scared about
284 2011-01-11 13:23:58 <davout> it's not illegal, so he should chill down or you should review your friends list :)
285 2011-01-11 13:24:07 <Ivy> well I don't want to defend my self...only... I want him to read more but not sure what to post first...
286 2011-01-11 13:24:19 <davout> just send him that link
287 2011-01-11 13:24:27 <Ivy> If I thought it was illegal I wouldn't be braggin abou it on my fb
288 2011-01-11 13:25:43 <davout> that would be making the assumption that are intelligent
289 2011-01-11 13:25:52 <davout> which you probably are
290 2011-01-11 13:26:07 <davout> but that kind of argument isn't very convincing

297 2011-01-11 13:52:10 <Ivy> hey yes.. sorry was to busy
298 2011-01-11 13:52:16 <Ivy> ok here's what I wrote...
299 2011-01-11 13:52:37 <Ivy> In the US and few other countries private currencies are legal. So not being a legal tender is not illegal, only opposite of the fiat currency. What's nice about it is that Bitcoin is not really private currency as it's based on the Open Source decentralized "cloud" volunteer community... so I'm not sure coming after me will be of any help to the Big Brother... Think bit-torrent hosting community...
300 2011-01-11 13:56:32 <Diablo-D3> ArtForzZz: okay I got an idea
301 2011-01-11 13:57:11 <Diablo-D3> ArtForzZz: take a blank x16 card, put a bunch of pci-e power connectors on it, 8 phases of VRM, and a pci-e bridge chip
302 2011-01-11 13:57:32 <Diablo-D3> ArtForzZz: and put four connectors on it parallel to the mobo.
303 2011-01-11 13:57:51 <Diablo-D3> ArtForzZz: then take four 40mm wide cards that plug into those connectors, and on each, put a 6970 and it's ram
304 2011-01-11 13:58:05 <Diablo-D3> ArtForzZz: and then put heatsinks all over it
305 2011-01-11 13:58:19 <Diablo-D3> ArtForzZz: plug those cards into the main card, put two 40mm fans at the ass end
306 2011-01-11 13:58:20 <Diablo-D3> and tada
307 2011-01-11 13:58:27 <Diablo-D3> the most powerful pile of shit ever
308 2011-01-11 14:00:01 <ArtForzZz> *shrug*
309 2011-01-11 14:01:12 <ArtForzZz> probably wont have enough fin area to cool those chips
310 2011-01-11 14:01:33 ArtForzZz is now known as ArtForz
311 2011-01-11 14:01:39 <Diablo-D3> well thats what I was thinking
312 2011-01-11 14:01:40 <Diablo-D3> so what you do
313 2011-01-11 14:01:59 <Diablo-D3> is put, say, half size full copper heatsinks on the memory
314 2011-01-11 14:02:08 <Diablo-D3> then a half size finned heatpipe on the gpu
315 2011-01-11 14:02:12 <Diablo-D3> with like two pipes in it
316 2011-01-11 14:02:24 <Diablo-D3> and go from fan side the whole way to the vents
317 2011-01-11 14:03:01 <ArtForz> hurrm
318 2011-01-11 14:03:18 <Diablo-D3> so the heat comes off the pipes at the ass end
319 2011-01-11 14:03:40 <Diablo-D3> and then leave a gap between the gpu and the fans for vrm heatsinks that stick out and shit
320 2011-01-11 14:03:51 <Diablo-D3> so it'd be a double 6990 or so
321 2011-01-11 14:03:55 <Diablo-D3> in 2 wide.
322 2011-01-11 14:04:04 <Diablo-D3> and it'd take every single ounce of power possible
323 2011-01-11 14:04:49 <ArtForz> whats the point of that crazy density?
324 2011-01-11 14:05:04 <Diablo-D3> because people will buy it.
325 2011-01-11 14:05:21 <ArtForz> errr... I doubt it
326 2011-01-11 14:06:31 <ArtForz> just take a stock 5970 or 5990, slap on a bigger vapor chamber or heatpipe cooler, a shroud over the whole thing and put 2 40mm fans on the ass end
327 2011-01-11 14:06:34 <Diablo-D3> also, this means up to 16 gpus in a conventional machine
328 2011-01-11 14:06:53 <Diablo-D3> assuming you can power the fucking thing
329 2011-01-11 14:08:18 <ArtForz> you could probably even lose the vapor chamber and just use a 4-5mm copper base plate
330 2011-01-11 14:09:01 <Diablo-D3> still
331 2011-01-11 14:09:05 <Diablo-D3> this could be some epic shit
332 2011-01-11 14:09:26 <ArtForz> and totally custom = hella expensive
333 2011-01-11 14:09:50 <ArtForz> modified cooler on ref PCBs is a lot cheaper
334 2011-01-11 14:10:28 <Diablo-D3> well the alternative is
335 2011-01-11 14:10:40 <Diablo-D3> produce normal PCBs that...
336 2011-01-11 14:10:46 <Diablo-D3> fit on both sides of the channel
337 2011-01-11 14:10:51 <Diablo-D3> so the left one is reversed
338 2011-01-11 14:11:06 <Diablo-D3> and the pci-e pins are one socket's worth up higher
339 2011-01-11 14:11:28 <Diablo-D3> and then you slam both of those down on a connector board that has two pcie plugs
340 2011-01-11 14:11:35 <Diablo-D3> with a pcie bridge chip
341 2011-01-11 14:11:39 <Diablo-D3> and then that plugs into the mobo
342 2011-01-11 14:12:19 <Diablo-D3> or put the bridge chip on the right board and send a cable over
343 2011-01-11 14:12:27 <Diablo-D3> you know, insert solution that makes sense here
344 2011-01-11 14:12:45 <Diablo-D3> and then with your left facing and right facing boards
345 2011-01-11 14:12:48 <Diablo-D3> put heatsinks all over them
346 2011-01-11 14:12:54 <Diablo-D3> but make sure the fins are every other spot
347 2011-01-11 14:13:04 <Diablo-D3> so when you put them together they interlock
348 2011-01-11 14:13:31 <Diablo-D3> and then BAM
349 2011-01-11 14:13:36 <Diablo-D3> instant double 6990
350 2011-01-11 14:14:02 <Diablo-D3> but you still need like 6 phase VRMs on both cards
351 2011-01-11 14:14:06 <Diablo-D3> and a bunch of plugs
352 2011-01-11 14:20:06 <Diablo-D3> ArtForz: is that too insane?
353 2011-01-11 14:20:43 <molecular> Ivy, exchange bitcoins at http://www.mtgox.com/
354 2011-01-11 14:20:52 <ArtForz> guess it could work
355 2011-01-11 14:21:13 <Ivy> yeah ... Im on it... reading...
356 2011-01-11 14:21:54 <ArtForz> basically create a nearly 2-slot cooler with lengthwise fins with decent spacing, put in every 2nd card backwards or upside down so the fin combs interlock
357 2011-01-11 14:22:10 <Diablo-D3> ArtForz: yup
358 2011-01-11 14:22:19 <Diablo-D3> you'd just need to mutate the pci-e connector
359 2011-01-11 14:22:47 <ArtForz> not really

362 2011-01-11 14:24:05 <ArtForz> if every 2nd card is upside down you could just create a board with 4 PCIe connectors in 2 slot spacing, a 48 lane bridge doing 16 -> 4*8 and a cable down to mainboard
363 2011-01-11 14:24:30 <molecular> guys, quick question? is 1.7mhash/s normal for nvidia g98? or is sth wrong with my setup?
364 2011-01-11 14:25:11 <ArtForz> sounds about right
365 2011-01-11 14:25:29 <ArtForz> g98 only has 8 shaders
366 2011-01-11 14:25:38 <molecular> ArtForz: thx, so there's a huge difference in computing-power between different cards?
367 2011-01-11 14:25:44 <ArtForz> yep
368 2011-01-11 14:25:56 <ArtForz> g98 = 8 shaders @ 1.3-1.4GHz
369 2011-01-11 14:25:56 <molecular> thanks a lot. that helped.
370 2011-01-11 14:26:06 <ArtForz> GF100 = 480 shaders
371 2011-01-11 14:26:13 <davout> gavinandersen: pong
372 2011-01-11 14:26:17 <molecular> allright
373 2011-01-11 14:26:19 <ArtForz> ati HD5870 = 1600 shaders @ 850MHz
374 2011-01-11 14:26:34 <Diablo-D3> ArtForz: ooh four
375 2011-01-11 14:26:37 <Diablo-D3> ArtForz: that could work
376 2011-01-11 14:26:53 <Diablo-D3> ArtForz: wait
377 2011-01-11 14:26:54 <molecular> artforz: does that means paralellizing using opencl >8 "threads" does do no good with only 8 shaders?
378 2011-01-11 14:26:57 <Diablo-D3> ArtForz: how would that work?
379 2011-01-11 14:27:10 <ArtForz> how would what work?
380 2011-01-11 14:27:26 <Diablo-D3> ArtForz: well, the pci-e connectors would still have to be short
381 2011-01-11 14:27:32 <Diablo-D3> so they plug into a bridge board
382 2011-01-11 14:27:51 <ArtForz> I was thinking put the bottom 4 cards normally on the mainboard
383 2011-01-11 14:27:59 <ArtForz> you'd have to go XL-ATX to fit that
384 2011-01-11 14:28:24 <Diablo-D3> who said four cards
385 2011-01-11 14:28:26 <Diablo-D3> its just two
386 2011-01-11 14:28:33 <ArtForz> actually it's 8
387 2011-01-11 14:28:43 <Diablo-D3> 2 for every 2 wide slot.
388 2011-01-11 14:28:50 <ArtForz> yep
389 2011-01-11 14:29:02 <Diablo-D3> you cant plug them into the mobo because the spacing would have to be EXACT
390 2011-01-11 14:29:07 <ArtForz> so?
391 2011-01-11 14:29:15 <Diablo-D3> as in
392 2011-01-11 14:29:20 <Diablo-D3> x16 x16
393 2011-01-11 14:29:23 <Diablo-D3> right next to each other
394 2011-01-11 14:29:30 <Diablo-D3> and holy shit imagine trying to plug that in

396 2011-01-11 14:29:43 <ArtForz> you'd need x16 x16 ? x16 ? x16 ? x16 ?
397 2011-01-11 14:29:56 <ArtForz> and yes, thats 9 slots
398 2011-01-11 14:30:01 <Diablo-D3> no I mean
399 2011-01-11 14:30:03 <Diablo-D3> you'd need
400 2011-01-11 14:30:07 <Diablo-D3> one right next to the other
401 2011-01-11 14:30:12 <ArtForz> why?
402 2011-01-11 14:30:15 <Diablo-D3> two cards?
403 2011-01-11 14:30:28 <ArtForz> hurrrrm
404 2011-01-11 14:30:33 <Diablo-D3> if you dont have the bridge board at the bottom you need two physical slots
405 2011-01-11 14:30:39 <ArtForz> yep
406 2011-01-11 14:30:39 <Diablo-D3> right next to each ther
407 2011-01-11 14:30:42 <ArtForz> well... no
408 2011-01-11 14:30:43 <Diablo-D3> and a lot of boards dont have that
409 2011-01-11 14:31:13 <Diablo-D3> so short changing it with a bridge board would work
410 2011-01-11 14:31:22 <ArtForz> the physical slot for the 2ndary cards is outside
411 2011-01-11 14:31:36 <Diablo-D3> you mean inside
412 2011-01-11 14:31:45 <ArtForz> no
413 2011-01-11 14:31:49 <Diablo-D3> wait
414 2011-01-11 14:31:54 <Diablo-D3> if the upside down slot is upsidedown
415 2011-01-11 14:31:57 <Diablo-D3> err
416 2011-01-11 14:32:00 * Diablo-D3 smacks self
417 2011-01-11 14:32:01 <ArtForz> yep
418 2011-01-11 14:32:05 <Diablo-D3> if the upside down slot is short
419 2011-01-11 14:32:15 <Diablo-D3> you use the bridge board ON THE TOP
420 2011-01-11 14:32:21 <ArtForz> yep
421 2011-01-11 14:32:39 <ArtForz> and just run a cable down on one end to a free x16 slot
422 2011-01-11 14:32:48 <Diablo-D3> ArtForz: no no
423 2011-01-11 14:32:50 <Diablo-D3> I got it even better
424 2011-01-11 14:33:02 <Diablo-D3> wait
425 2011-01-11 14:33:03 <Diablo-D3> maybe you do
426 2011-01-11 14:33:12 <Diablo-D3> put the bridge on the top for _both cards_
427 2011-01-11 14:33:19 <ArtForz> that would also work
428 2011-01-11 14:33:20 <Diablo-D3> and then just plug it in with a cable
429 2011-01-11 14:33:26 <ArtForz> yep
430 2011-01-11 14:33:29 <Diablo-D3> infact, that could be superior anyhow
431 2011-01-11 14:33:36 <Diablo-D3> built in cable allows you to plug it in anywhere
432 2011-01-11 14:33:50 <Diablo-D3> it wouldnt have to be over the slot
433 2011-01-11 14:33:52 <Diablo-D3> but that'd be weird
434 2011-01-11 14:34:01 <Diablo-D3> and probably they wouldnt let me sell it
435 2011-01-11 14:34:01 <ArtForz> you'd be a few mm offset to a normal slot, but who cares
436 2011-01-11 14:34:17 <Diablo-D3> although if I just leave the cable in there
437 2011-01-11 14:34:26 <Diablo-D3> I could just make it part of the housing
438 2011-01-11 14:34:38 <Diablo-D3> ArtForz: btw
439 2011-01-11 14:34:41 <Diablo-D3> theres a small problem
440 2011-01-11 14:34:47 <Diablo-D3> where do I plug the pcie plugs in?
441 2011-01-11 14:34:49 <Diablo-D3> if I take up the top
442 2011-01-11 14:35:07 <ArtForz> look at where the PCIe connector is and where the power plugs are
443 2011-01-11 14:35:15 <Diablo-D3> they're only slightly offset
444 2011-01-11 14:35:16 <ArtForz> they're at different ends of the cards
445 2011-01-11 14:35:28 <Diablo-D3> they're not if I have two sided pcie.
446 2011-01-11 14:35:41 <ArtForz> the top card is upside down, not backwards
447 2011-01-11 14:36:02 <Diablo-D3> yes, but pcie connectors are top loading
448 2011-01-11 14:36:06 <ArtForz> so?
449 2011-01-11 14:36:24 <Diablo-D3> btw, this could actually be solved
450 2011-01-11 14:36:32 <Diablo-D3> the bridge board would have pass through connectors
451 2011-01-11 14:36:36 <ArtForz> yep
452 2011-01-11 14:36:47 <Diablo-D3> so you plug them into the middle of the bridge
453 2011-01-11 14:36:52 <Diablo-D3> and then the cards just plug into the bridge
454 2011-01-11 14:36:55 <ArtForz> you'd have to run a cable for power up to the bridge board from the 2ndary card
455 2011-01-11 14:36:55 <Diablo-D3> and its just a dummy connector
456 2011-01-11 14:37:09 <ArtForz> for primary you can just plug in directly
457 2011-01-11 14:37:12 <Diablo-D3> well no
458 2011-01-11 14:37:15 <Diablo-D3> you'd use it for both
459 2011-01-11 14:37:22 <Diablo-D3> since both cards would be fabbed exactly alike
460 2011-01-11 14:37:43 <Diablo-D3> they wouldnt stick out at the top, they'd face internally
461 2011-01-11 14:37:52 <ArtForz> yep
462 2011-01-11 14:37:56 <Diablo-D3> so just use cables on both
463 2011-01-11 14:38:21 <ArtForz> and then you dont need to to use the bulky mini-fit jr. housings
464 2011-01-11 14:38:31 <Diablo-D3> the what?
465 2011-01-11 14:38:44 <ArtForz> mini-fit jr.
466 2011-01-11 14:39:04 <Diablo-D3> woah those have names?
467 2011-01-11 14:39:08 <ArtForz> yep
468 2011-01-11 14:39:10 <ArtForz> thats the contact housing type used for PCIe power, ATX, EPS, ...
469 2011-01-11 14:39:16 <Diablo-D3> hah
470 2011-01-11 14:39:22 <Diablo-D3> I just call them pcie power plugs
471 2011-01-11 14:39:57 <ArtForz> anyways, theres connectors with similar current ratings that take up less than 1/3 the space
472 2011-01-11 14:40:23 <Diablo-D3> yeah but those cost more
473 2011-01-11 14:40:25 <EvanR-work> almost 15G in the pool
474 2011-01-11 14:40:33 <ArtForz> not really much more
475 2011-01-11 14:40:34 <Diablo-D3> you'd just need like 1 inch cables
476 2011-01-11 14:40:45 <Diablo-D3> yeah but these are already common for the assembly line
477 2011-01-11 14:41:22 <Diablo-D3> ArtForz: btw, we're even still over thinking this
478 2011-01-11 14:41:27 <Diablo-D3> we dont need 2 pcie
479 2011-01-11 14:41:29 <Diablo-D3> we need one
480 2011-01-11 14:41:36 <Diablo-D3> and then use TWO cables.
481 2011-01-11 14:42:03 <Diablo-D3> or not even two
482 2011-01-11 14:42:11 <Diablo-D3> wait yes two
483 2011-01-11 14:42:13 <Diablo-D3> fawk
484 2011-01-11 14:42:18 <ArtForz> yup, 2
485 2011-01-11 14:42:25 <Diablo-D3> I cant figure out how to route it
486 2011-01-11 14:42:28 <Diablo-D3> oh wait
487 2011-01-11 14:42:29 <Diablo-D3> yes I can
488 2011-01-11 14:42:43 <Diablo-D3> the right of the "card" plugs into the mobo
489 2011-01-11 14:42:51 <Diablo-D3> the left card points _down_
490 2011-01-11 14:43:07 <Diablo-D3> cable loops up to the bridge
491 2011-01-11 14:43:18 <Diablo-D3> then the right card plugs into the bridge directly
492 2011-01-11 14:43:31 <Diablo-D3> and then the bridge sends a cable over the right card and then down to the plug
493 2011-01-11 14:43:44 nathan7 has quit (Ping timeout: 272 seconds)
494 2011-01-11 14:43:58 <EvanR-work> so the fast the pool gets, the faster i get coins from it, given constant hash rate
495 2011-01-11 14:44:01 <EvanR-work> fastser*
496 2011-01-11 14:44:20 <ArtForz> well... you get less coins more often
497 2011-01-11 14:44:28 <Diablo-D3> ArtForz: then again, the left card's loop could be on the inside
498 2011-01-11 14:44:37 <Diablo-D3> by seeing if anyone makes a cabled pci-e extender
499 2011-01-11 14:44:42 <Diablo-D3> instead of ribbon
500 2011-01-11 14:44:58 <EvanR-work> ArtForz: yeah, but your average rate doesnt go up?
501 2011-01-11 14:45:18 <ArtForz> nope
502 2011-01-11 14:45:26 <Diablo-D3> ArtForz: actually, if we could move the pci-e plug altogether, we'd be better off
503 2011-01-11 14:45:35 <Diablo-D3> actually
504 2011-01-11 14:45:39 <Diablo-D3> thats the trick I think
505 2011-01-11 14:45:43 <Diablo-D3> cards only need like x4
506 2011-01-11 14:45:48 <EvanR-work> ah so in the pool, i just plug my hash rate into the difficulty 32 formula to get my average coin rate
507 2011-01-11 14:46:03 <ArtForz> yep
508 2011-01-11 14:46:03 <Diablo-D3> plug the data pins of the bus into existing compatible cables
509 2011-01-11 14:46:17 <Diablo-D3> at the end of the card, near the vents
510 2011-01-11 14:46:23 <Diablo-D3> and then plug into the bridge
511 2011-01-11 14:46:38 <Diablo-D3> or something
512 2011-01-11 14:48:00 <Diablo-D3> ArtForz: because you cant route the top pcie lines
513 2011-01-11 14:48:12 <Diablo-D3> the whole board is designed them for coming in the bottom
514 2011-01-11 14:48:29 <Diablo-D3> so its easier to subvert the pins and move them up a few mm and do something else with them
515 2011-01-11 14:49:22 nathan7 has joined

517 2011-01-11 14:49:46 <Diablo-D3> ArtForz: I wonder if the pci-e ribbons COULD be rounded
518 2011-01-11 14:49:48 <Diablo-D3> they seem pretty thick
519 2011-01-11 14:51:01 slush has quit (Quit: Leaving.)
520 2011-01-11 14:51:24 <ArtForz> they're really not
521 2011-01-11 14:51:39 <ArtForz> the cable iself is thin, the shielding is kinda bulky
522 2011-01-11 14:52:17 <Diablo-D3> the bridge would still be better on the bottom though
523 2011-01-11 14:54:04 <Diablo-D3> they make completely plastic right angle adapters
524 2011-01-11 14:54:31 skeledrew has quit (Quit: Instantbird 0.3a1pre)
525 2011-01-11 14:54:42 <Diablo-D3> so you'd plug that into the end of the bridge board at the bottom
526 2011-01-11 14:54:51 <Diablo-D3> then right above it would be the left card
527 2011-01-11 14:55:06 <Diablo-D3> so when you shove down on the left card, it shoves down on the right angle connector
528 2011-01-11 14:55:19 <Diablo-D3> using the plastic frame around it
529 2011-01-11 14:56:04 <Diablo-D3> ArtForz: ooh I figured it out
530 2011-01-11 14:56:21 skeledrew has joined
531 2011-01-11 14:56:34 <Diablo-D3> so taking that bottom bridge + right angle connector
532 2011-01-11 14:56:45 <Diablo-D3> you put a mobo connector on both boards
533 2011-01-11 14:57:11 <Diablo-D3> the left one plugs into ANOTHER right angle connector
534 2011-01-11 14:57:14 <Diablo-D3> on the top of the bridge board
535 2011-01-11 14:57:19 <Diablo-D3> the other one plugs in using a cable.
536 2011-01-11 14:57:42 <Diablo-D3> so, ONE cable.
537 2011-01-11 15:01:40 <Diablo-D3> clearly Ive gone insane.
538 2011-01-11 15:08:01 <Diablo-D3> ArtForz: maybe this is just a bad idea

575 2011-01-11 17:20:35 <LobsterMan> heh the pool is approaching that
576 2011-01-11 17:20:45 <ArtForz> yup
577 2011-01-11 17:21:25 <LobsterMan> are you going to be expanding your gpu farm any more?
578 2011-01-11 17:21:31 <ArtForz> nope
579 2011-01-11 17:25:10 <LobsterMan> it's 6 blocks to confirm a transaction, correct?
580 2011-01-11 17:25:28 <ArtForz> yeah, 6 is what the stock client uses for display

584 2011-01-11 17:37:28 <UukGoblin> is gribble down or were the really no mtgox trades today?

589 2011-01-11 17:38:01 <LobsterMan> i guess no trades
590 2011-01-11 17:38:33 <sipa> so we just define the prefix jigga- to mean 110*10^9
591 2011-01-11 17:38:41 <sipa> and we're at 1.21 jiggahash!

621 2011-01-11 19:07:23 <pidpawel> have anyone tried generating bitcoins on ps3?
622 2011-01-11 19:08:40 <mizerydearia> http://www.youtube.com/watch?v=qID7Jsu1K0s
623 2011-01-11 19:09:06 <luke-jr> pidpawel: not sure if anyone's done it, but it would be crap
624 2011-01-11 19:09:38 <pidpawel> why?
625 2011-01-11 19:10:07 <luke-jr> because it's CPU+SPUs combined would be less than a good GPU?
626 2011-01-11 19:11:00 <ArtForz> even less than a really mediocre GPU
627 2011-01-11 19:12:38 <pidpawel> ok. do you happen to know whether mobile ati gpu's have opencl support?
628 2011-01-11 19:12:57 <ArtForz> well, if they're 4xxx or 5xxx based, yes
629 2011-01-11 19:12:58 <luke-jr> afaik it's not a chipset function, but a driver thing
630 2011-01-11 19:13:11 <luke-jr> and no free drivers do yet unless for some bleeding edge code
631 2011-01-11 19:13:43 <pidpawel> i will try downloading newest drivers for my 5650 card.
632 2011-01-11 19:13:49 <ArtForz> yes yes, nonfree drivers eat kittens
633 2011-01-11 19:14:31 <Diablo-D3> what, the fusion?
634 2011-01-11 19:14:42 <Diablo-D3> they're 5xxx
635 2011-01-11 19:14:51 <Diablo-D3> but its only supposed to be as powerful as an IGP
636 2011-01-11 19:14:56 <Diablo-D3> its meant to be an atom killer
637 2011-01-11 19:15:18 <ArtForz> Mobile 5650 is a redwood core -> same as discrete HD5670 just lower clock
638 2011-01-11 19:16:35 <ArtForz> seems the come with various core clocks depending on OEM, between 450 and 650MHz
639 2011-01-11 19:16:58 <ArtForz> ~60Mh/s @ 650MHz core
640 2011-01-11 19:17:34 <Diablo-D3> night all
641 2011-01-11 19:18:12 <pidpawel> my version is 450MHz core and 790MHz memory
642 2011-01-11 19:18:30 <ArtForz> mem clock doesnt matter really
643 2011-01-11 19:18:42 <ArtForz> so... 60/650*450 ... about 41.5Mh/s
644 2011-01-11 19:19:36 <pidpawel> it will still be much more than what i have now :)
645 2011-01-11 19:19:45 <pidpawel> im running 1-2khps on cpu
646 2011-01-11 19:20:13 <ArtForz> mhps you mean?
647 2011-01-11 19:20:30 <pidpawel> yes, ofc ;)
648 2011-01-11 19:20:59 <ArtForz> a PS3 cell should be able to get about 15Mh/s, 23Mh/s if it has a 1-cycle rotate opcode
649 2011-01-11 19:21:57 <pidpawel> i dont have ps3 but i was couroius how fast would it be.
650 2011-01-11 19:22:57 Diablo-D3 has quit (Ping timeout: 240 seconds)
651 2011-01-11 19:24:11 <ArtForz> well, it's about as fast as a modern high-end CPU, but outclassed by a $70 GPU by a factor of 3-4
652 2011-01-11 19:25:48 <ArtForz> and a $500 GPU is roughly another order of magnitude faster...
653 2011-01-11 19:27:35 <pidpawel> i know that but still i dont want to spend a lot of money just to have my e-penis growing... :>
654 2011-01-11 19:27:54 <ArtForz> nah, but it explains why nobody bothers with a PS3 miner

658 2011-01-11 19:38:17 <cdecker> I'm having problems understanding the tx message
659 2011-01-11 19:38:43 <ArtForz> whres the problem?
660 2011-01-11 19:39:14 <cdecker> Oh hi Artforz
661 2011-01-11 19:39:30 <cdecker> Problem is I don't know where the txin stop and txout start
662 2011-01-11 19:39:43 <x6763> cdecker: yeah, i'm also having problems with that, too
663 2011-01-11 19:40:00 <ArtForz> they're vectors, they have a count...
664 2011-01-11 19:40:12 <cdecker> Oh nice
665 2011-01-11 19:40:38 <lfm> the count fields are veriable length iirc
666 2011-01-11 19:40:46 <ArtForz> yep
667 2011-01-11 19:41:00 <cdecker> So the first thing to read is the variable size?
668 2011-01-11 19:41:07 <ArtForz> yep
669 2011-01-11 19:41:13 mtgox has joined
670 2011-01-11 19:41:21 <cdecker> I wonder why that isn't explained on the Wiki
671 2011-01-11 19:41:27 <ArtForz> it should be
672 2011-01-11 19:41:28 <x6763> what is the "signature" or "script" of the TxIn?
673 2011-01-11 19:41:41 <newsham> have people here used bitcoinmorpheus to deposit money into mtgox?
674 2011-01-11 19:41:46 <ArtForz> it's the signature script
675 2011-01-11 19:41:53 <cdecker> A simple forth like script to check the validity
676 2011-01-11 19:42:00 <ArtForz> yep
677 2011-01-11 19:42:04 <x6763> how do you tell how long the script is?
678 2011-01-11 19:42:05 <cdecker> Check this
679 2011-01-11 19:42:08 <cdecker> https://en.bitcoin.it/wiki/Script
680 2011-01-11 19:42:10 <ArtForz> it's a vector of bytes
681 2011-01-11 19:42:20 <ArtForz> again, with a variable length length field
682 2011-01-11 19:42:28 <lfm> the scripts have their own count lengths
683 2011-01-11 19:42:30 <x6763> ah, ok, i didn't see that anywhere yet
684 2011-01-11 19:42:42 <cdecker> Anybody has a clue why Satoshi thought it useful to have Unsigned Integer 64 length?
685 2011-01-11 19:42:54 <ArtForz> nope
686 2011-01-11 19:42:57 <x6763> thanks ArtForz
687 2011-01-11 19:43:01 <cdecker> That's longer than what fits on any disk
688 2011-01-11 19:43:02 <newsham> cdecker: though std clients are pretty restrictive in what scripts they'll accept right now
689 2011-01-11 19:43:11 <ArtForz> all serialized vectors have the variable length #items prefix
690 2011-01-11 19:43:12 <cdecker> Yeah
691 2011-01-11 19:43:28 <ArtForz> and thats prety easy to read
692 2011-01-11 19:43:46 <cdecker> ArtForz: so anytime an array is in the doc I should first read the variable length?
693 2011-01-11 19:43:48 <LobsterMan> ;;bc,calc 800
694 2011-01-11 19:43:52 <gribble> The average time to generate a block at 800 Khps, given current difficulty of 16307.48285682 , is 2 years, 40 weeks, 3 days, 7 hours, 28 minutes, and 51 seconds
695 2011-01-11 19:43:55 <lfm> just when its unsigned it makes it plain that it will never be negative
696 2011-01-11 19:43:57 <newsham> also odd -- some timestamps are 64bits and some are 32bits
697 2011-01-11 19:44:01 <ArtForz> yep
698 2011-01-11 19:44:02 AAA_awright_ is now known as AAA_awright
699 2011-01-11 19:44:20 <ArtForz> read 1 byte, if it's < 253, thats #items, if it's == 253 read a WORD, if it's == 254 read a DWORd, if its=255 read a QWORD
700 2011-01-11 19:44:36 <ArtForz> so really quite simple
701 2011-01-11 19:44:49 <cdecker> Yup got that sorted out pretty early
702 2011-01-11 19:44:55 <ArtForz> at least compared to crazy encodings like adobe flash
703 2011-01-11 19:45:09 <newsham> they shoulda gone with BER!
704 2011-01-11 19:45:11 <newsham> *ducks*
705 2011-01-11 19:45:13 <cdecker> (even if Java doesn't have unsigned longs and 255,254 and 253 are negative in Java)
706 2011-01-11 19:45:30 <ArtForz> hey, dont blame C coders for java stupidity
707 2011-01-11 19:45:38 <cdecker> Hehe, I won't
708 2011-01-11 19:45:44 <x6763> cdecker: you're using java?
709 2011-01-11 19:45:47 <newsham> int x = (int)thechar; if(x<0) x+= 128;
710 2011-01-11 19:45:49 <cdecker> What I will blame them is Little endian...
711 2011-01-11 19:45:55 <ArtForz> "nobody uses unsigned numbers"
712 2011-01-11 19:46:23 <cdecker> There's a reason big endian is also called network byte order
713 2011-01-11 19:46:28 <ArtForz> well, it's consistent little endian except for IP and port# in CAddress
714 2011-01-11 19:46:46 <ArtForz> yes, because 30 years ago there were mostly BE machines on ARPAnet
715 2011-01-11 19:46:55 <lfm> and the sha256 stuff
716 2011-01-11 19:46:57 <ArtForz> thats why network endian == BE
717 2011-01-11 19:46:59 <newsham> just write marshalling primitives for each of your data types and then compose them.
718 2011-01-11 19:46:59 <cdecker> Ah the good old days
719 2011-01-11 19:47:08 <ArtForz> errr... not quite
720 2011-01-11 19:47:10 <newsham> shouldnt matter much that java chose signed numbers, or things like that..
721 2011-01-11 19:47:42 <ArtForz> but yeah, SHA256 defines its input/output to be BE
722 2011-01-11 19:47:51 <lfm> newsham yes java can handel it, its just some extra overhead
723 2011-01-11 19:47:58 <newsham> lfm: just barely
724 2011-01-11 19:48:00 <ArtForz> and we then take the output and intepret is as a 256 bit LE integer
725 2011-01-11 19:48:49 <donpdonp> "The term big-endian originally comes from Jonathan Swift's satirical novel Gulliverâs Travels..." where competing tribes mandated cracking open eggs either at the little end or the big end, hence endianess was used to identify two groups (from wikipedia)
726 2011-01-11 19:49:07 <newsham> one little two little three little endian
727 2011-01-11 19:49:24 <cdecker> Long live the endian wars :D
728 2011-01-11 19:50:09 <newsham> big endian would make more sense if your pointer pointed ot the last byte (or perhaps one beyond the last byte) of the number :)
729 2011-01-11 19:50:59 <ArtForz> well, and then there's middle endian
730 2011-01-11 19:51:12 <x6763> cdecker: are you using any library like netty to handle network stuff?
731 2011-01-11 19:51:16 <ArtForz> aka NUXI byte order
732 2011-01-11 19:51:36 <ArtForz> BE is UNIX, LE is XINU
733 2011-01-11 19:51:41 <lfm> donpdonp yes it was ment to point out the trivialness of most disagreements and it applies to the endian wars for computers too. there is not really any significant advantage of either. but people get very attached to one way or the other
734 2011-01-11 19:51:45 <cdecker> x6763: no I'm coding it directly on top of nio Channels
735 2011-01-11 19:52:07 * luke-jr encoders variable length integers as UTF-8 sometimes <.<
736 2011-01-11 19:52:37 <newsham> can we do editor wars next?
737 2011-01-11 19:52:42 <ArtForz> actually LE has a decent advantage for bignums
738 2011-01-11 19:52:46 <newsham> only an emacs user would think big endian is cool!
739 2011-01-11 19:52:46 <luke-jr> nano!
740 2011-01-11 19:52:57 <luke-jr> I can never remember endianness stuff
741 2011-01-11 19:53:00 <cdecker> emacs!
742 2011-01-11 19:53:05 <luke-jr> I just know x86's endian sucks
743 2011-01-11 19:53:11 <ArtForz> why?
744 2011-01-11 19:53:17 <newsham> artforz: unless your pointer points to the last byte of a big-endian series.
745 2011-01-11 19:53:24 <luke-jr> because it's out of order
746 2011-01-11 19:53:25 <x6763> cdecker: ah, ok...i'm writing this in clojure and not being very familiar with the java libraries, i just grabbed netty and have been using that...i eventually realized that it's ChannelBuffer can read unsigned numbers for you
747 2011-01-11 19:53:26 <cdecker> luke-jr: it's little endian on x86
748 2011-01-11 19:53:38 <luke-jr> 89abcdef 01234567
749 2011-01-11 19:53:48 <ArtForz> for a bignum you usually have (#elems) (elems)

751 2011-01-11 19:54:06 darrob has joined
752 2011-01-11 19:54:15 <newsham> s/byte/leg/
753 2011-01-11 19:54:25 <ArtForz> so for example for adding 2 on x86, you read #items, start adding at the next = smallest elem and walk forwards carrying the carry
754 2011-01-11 19:54:54 <ArtForz> with BE you skip forward, then walk backwards, not very cache freindly if both have different #elems
755 2011-01-11 19:55:20 <newsham> art: unless your pointers are already pre-skipped forward and point to one beyond the end.
756 2011-01-11 19:55:31 <lfm> artforz "forward" and "backward" can be reletive too. and in fact computers caount/move either direction equally well
757 2011-01-11 19:55:53 <ArtForz> errr... not really
758 2011-01-11 19:56:19 <ArtForz> then you have to also allocate memory the other way around and store pointers beyond the end of the mem block
759 2011-01-11 19:56:20 <luke-jr> maybe I shoudl blame decimal >âº
760 2011-01-11 19:56:29 <newsham> art: yup.
761 2011-01-11 19:56:32 <cdecker> I never thought about that, with LE you'd actually need less cache :D
762 2011-01-11 19:56:36 <newsham> art: we already do that with stacks :)
763 2011-01-11 19:56:38 <luke-jr> decimal has numbers written right-to-left
764 2011-01-11 19:56:52 <newsham> (at least on most architectures.. pa risc can take a hike)
765 2011-01-11 19:57:10 <ArtForz> yes, and cpu caches have special optimizations for stack
766 2011-01-11 19:57:12 <luke-jr> Tonal too, but it probably got it from decimal <.<
767 2011-01-11 19:57:27 <ArtForz> while burst memory is really designed to be read/written in one direction
768 2011-01-11 19:57:40 <newsham> oh, i see what you're saying. burst prefetch stuff
769 2011-01-11 19:57:46 <ArtForz> yep
770 2011-01-11 19:57:50 <lfm> luke-jr yes they are called "arabic" numerals and lo and behold arabic write right - to - left
771 2011-01-11 19:58:11 <ArtForz> well, most-significant-first makes for easier sorting
772 2011-01-11 19:58:15 <slush> what files I have to delete from .bitcoin directory to force client rescan blocks and find transaction for my current wallet.dat?
773 2011-01-11 19:58:18 <newsham> or as we clal them in america "terror numbers"
774 2011-01-11 19:58:25 <ArtForz> iirc just blkindex.dat
775 2011-01-11 19:58:35 <slush> thx, I'll try
776 2011-01-11 19:59:38 <newsham> nobody's used bitcoinmorpheus to xfer to mtgox?
777 2011-01-11 20:00:24 <x6763> newsham: i haven't, but i'm considering it...i'd also like to know if anyone has used bitcoinmorpheus

797 2011-01-11 20:10:18 <newsham> pass on the alex jones, thank you very much
798 2011-01-11 20:10:57 <mizerydearia> strange, less than 10,000 results for Austerity. Almost two times as much for wikileaks. Why isn't wikileaks the word of the year? ^_^

803 2011-01-11 20:12:04 <newsham> wikileaks is a proper noun.
804 2011-01-11 20:12:38 djx has joined
805 2011-01-11 20:13:32 <EvanR-work> wikileaks is a 'real word' now?
806 2011-01-11 20:13:55 <newsham> no, its a proper noun
807 2011-01-11 20:14:30 <cdecker> it's a verb
808 2011-01-11 20:14:34 <cdecker> I Wikileak
809 2011-01-11 20:14:38 <cdecker> You wikileak
810 2011-01-11 20:14:41 <ArtForz> call a wikiplumber
811 2011-01-11 20:14:42 <cdecker> We all leak
812 2011-01-11 20:15:03 <cdecker> It's called a Wiki Sanitation Manager

814 2011-01-11 20:15:13 <x6763> cdecker and ArtForz: does this look right for TxIn and TxOut? https://en.bitcoin.it/wiki/Protocol_specification#tx

818 2011-01-11 20:15:58 <cdecker> x6763: You added the variable length to the script?
819 2011-01-11 20:16:11 <x6763> cdecker: yeah, for both TxIn and TxOut
820 2011-01-11 20:16:26 <cdecker> I'd rather go and define a variable string which starts with the length
821 2011-01-11 20:16:26 <ArtForz> someone should rewrite that to point out that we use the variable-length prefix for all var-length vectors
822 2011-01-11 20:16:40 <cdecker> And var length strings
823 2011-01-11 20:16:51 <ArtForz> doesnt matter if it's a vector of bytes, TXin/outs, CInvs or CAddrs

829 2011-01-11 20:17:30 <Myckel> ArtForz, which file contains the asm code?
830 2011-01-11 20:17:34 <cdecker> Strangely addr already has an explicit var_int in front
831 2011-01-11 20:17:54 <ArtForz> main.cpp
832 2011-01-11 20:17:58 <Myckel> ok
833 2011-01-11 20:18:03 <ElectRo`> i have to take a manning and wipe the wikileaks from my assange
834 2011-01-11 20:18:07 <djx> hi all
835 2011-01-11 20:18:14 <newsham> electro: eek
836 2011-01-11 20:18:15 <djx> is there a bitcoin roadmap online
837 2011-01-11 20:18:34 <djx> for relases
838 2011-01-11 20:19:06 <ArtForz> it dos?
839 2011-01-11 20:19:07 <lfm> djx no. releases are released when they're needed and ready~
840 2011-01-11 20:19:37 tcatm has quit (Quit: leaving)
841 2011-01-11 20:19:46 <x6763> cdecker: yeah, a lot already explicitly have var_ints listed...i prefer them to be explicit...my problem with TxIn and TxOut was that all it said was 'script', which told me nothing about the type of data i was supposed to be dealing with...so now i changed it to char[], since it's supposed to be a bunch of bytes
842 2011-01-11 20:19:53 <djx> when i use bitcoin over tor, it sends all the data over tor?
843 2011-01-11 20:20:09 <djx> would it be anonymous, i mean
844 2011-01-11 20:20:34 <lfm> djx depends how you distributre your addreses
845 2011-01-11 20:20:39 <ArtForz> btw, shouldnt "start count" in getblocks also be a var_int
846 2011-01-11 20:20:50 <djx> what do you mean
847 2011-01-11 20:20:58 ApertureScience has quit (Quit: This a triumph,I'm making a note here HUGE SUCCESS!)
848 2011-01-11 20:21:15 <djx> would i need a seperate address, or would i have to generate a whole new wallet
849 2011-01-11 20:21:17 <x6763> ArtForz: yeah, someone just wrote it out completely instead of typing "var_int"...assuming you're looking at the same page
850 2011-01-11 20:21:31 <ArtForz> right now the wiki says "variable length integer" while it uses var_int everywhere else
851 2011-01-11 20:21:32 <ArtForz> yep
852 2011-01-11 20:21:41 <luke-jr> who is Casascius?
853 2011-01-11 20:21:44 <EvanR-work> djx: as long as no one gets your wallet, you can keep one wallet
854 2011-01-11 20:21:45 <luke-jr> I want to send him some TBC
855 2011-01-11 20:21:51 <lfm> djx if you tell people on irc what bitcoin address to send money to then any transaction to that address is not private, it is public
856 2011-01-11 20:21:59 <x6763> ArtForz: i changed it for getblocks
857 2011-01-11 20:22:07 <djx> lfm: well yeah
858 2011-01-11 20:22:13 <lfm> ya
859 2011-01-11 20:22:15 <djx> i'd have to be on tor irc
860 2011-01-11 20:22:33 <ArtForz> and yeah tx is missing tx_in count and tx_out count in this notation
861 2011-01-11 20:22:38 <lfm> itd still be associated with your irc id then
862 2011-01-11 20:22:52 <luke-jr> â¦
863 2011-01-11 20:22:53 <EvanR-work> hes asking about associating his ip with the transaction
864 2011-01-11 20:22:53 <djx> i assume it would be a tor-only id
865 2011-01-11 20:22:58 <EvanR-work> on his end
866 2011-01-11 20:22:58 <luke-jr> Casascius?
867 2011-01-11 20:23:05 <EvanR-work> by the isp
868 2011-01-11 20:23:13 <x6763> ArtForz: hmmm..sure is, i'll change that too
869 2011-01-11 20:23:19 <lfm> i dont assume that. some people dont
870 2011-01-11 20:24:12 <EvanR-work> if you trust bitcoin like you trust tor, then your stuff is already anonymous. as long as you dont give your name out when you give your address out
871 2011-01-11 20:24:36 <lfm> djx in fact bitcoin over tor seems to buy you very little. bitcoin txns are pretty annonymous on the bitcoin net already
872 2011-01-11 20:24:55 <djx> i'll trust that closer to version 1.0
873 2011-01-11 20:25:16 <luke-jr> EvanR-work: AND use a new address each time
874 2011-01-11 20:25:18 <ArtForz> we still need a bunch of changes to make bitcoin-over-tor interesting
875 2011-01-11 20:25:18 <EvanR-work> you can also run your own generator
876 2011-01-11 20:25:21 <EvanR-work> that helps
877 2011-01-11 20:25:25 <EvanR-work> luke-jr: yes
878 2011-01-11 20:25:31 <lfm> djx huh? I dont think ver 1 will use a different security modle
879 2011-01-11 20:25:33 <djx> i need a computer with a gpu
880 2011-01-11 20:25:38 <djx> this laptop sucks
881 2011-01-11 20:25:58 <EvanR-work> it doesnt have to actually generate
882 2011-01-11 20:26:11 <EvanR-work> just hide the fact that you are the one who sent the coins
883 2011-01-11 20:26:14 <djx> is there a way to distribute the generation
884 2011-01-11 20:26:15 <EvanR-work> from neaby nodes
885 2011-01-11 20:26:27 <djx> like a distributed client on my friend's gpus

895 2011-01-11 20:28:06 <djx> is it worth it to run a pool, if i just have a crappy laptop with no gpu
896 2011-01-11 20:28:24 <kupo> I'm glad however that more and more people care about bitcoin over tor

905 2011-01-11 20:31:23 <lfm> djx depends how fast your machine and how long you run it
906 2011-01-11 20:32:21 <x6763> djx: a few weeks ago, i had 2 old machines running on slush's pool for a few days or so and got about 0.2 BTC out of it...better than nothing, but the cost of the electricity i was using outweighed any immediate gain (eventually those coins might be worth more than the electricity i used, though)

926 2011-01-11 20:36:49 <ArtForz> should be 1 iirc
927 2011-01-11 20:37:41 <TD> yeah version numbers are always 1, currently

930 2011-01-11 20:38:09 <ArtForz> you forgot to skip the header checksum
931 2011-01-11 20:38:31 <cdecker> Sounds reasonable, let's have a look
932 2011-01-11 20:38:35 <TD> hah, webhex

934 2011-01-11 20:38:45 <x6763> cdecker: yeah, that number you gave us is the checksum

958 2011-01-11 20:49:11 Daviey has joined
959 2011-01-11 20:49:31 <luke-jr> so it looks like I can actually send bitcoin to a password rather than a key? :P
960 2011-01-11 20:49:51 <djx> hm?
961 2011-01-11 20:50:04 <luke-jr> djx: the infra doesn't require using keys
962 2011-01-11 20:50:27 <djx> what do you mean
963 2011-01-11 20:50:31 <TD> no, today you have to use keys
964 2011-01-11 20:50:45 <luke-jr> djx: it's conceivable to send bitcoins to a password rather than an address
965 2011-01-11 20:50:48 <TD> in theory you could write a script that allowed passwords instead of target addresses
966 2011-01-11 20:50:55 <TD> but the network would reject these scripts as non standard
967 2011-01-11 20:51:08 <luke-jr> TD: the network rejects "non-standard" scripts? -.-
968 2011-01-11 20:51:11 <TD> yes
969 2011-01-11 20:51:24 <djx> sounds a little fascists to me
970 2011-01-11 20:51:28 <TD> you could send a patch to gavin or satoshi if you wanted a new type of script to become common.
971 2011-01-11 20:51:29 <djx> damn this laptop
972 2011-01-11 20:51:36 <lfm> how would passwords be uniue?
973 2011-01-11 20:51:45 <lfm> unique
974 2011-01-11 20:53:09 <TD> why would you want a password anyway
975 2011-01-11 20:53:09 <djx> is it gonna take a while for my transactions to be confirmed?
976 2011-01-11 20:53:16 <djx> i just moved my wallet to a new computer
977 2011-01-11 20:53:16 <TD> bearing in mind it could be brute forced ....
978 2011-01-11 20:53:45 <lfm> confirmation takes an average of 1 hour give or take
979 2011-01-11 20:54:35 <lfm> if you want a simple username password for bitcoin just create a mybitcoins.com account
980 2011-01-11 20:58:19 <luke-jr> TD: wait, so scripts are only rejected by block generators?
981 2011-01-11 20:58:30 <luke-jr> so I could still use passwords, so long as I generate my own block?
982 2011-01-11 20:58:42 <TD> no
983 2011-01-11 20:58:50 <luke-jr> TD: passwords are easier printed and shared on paper
984 2011-01-11 20:58:53 <TD> even if you generate your own block, other nodes won't accept it
985 2011-01-11 20:59:03 <luke-jr> TD: in that case, not even satoshi could fix it
986 2011-01-11 20:59:11 <luke-jr> since it would require *every node* to upgrade
987 2011-01-11 20:59:16 <TD> no
988 2011-01-11 20:59:17 <TD> just the majority
989 2011-01-11 20:59:20 <luke-jr> (in which case we could replace the entire system)
990 2011-01-11 20:59:31 <luke-jr> TD: and the minority that don't fork their own block chain?
991 2011-01-11 20:59:34 <TD> which has been done before. see the september integer overflow incident
992 2011-01-11 21:00:31 <luke-jr> TD: basically, that makes it no different than breaking ANY rule in bitcoin
993 2011-01-11 21:00:34 <TD> i think lfm has a point. if for some reason you don't know the address of the person you're sending coins to, but you will be able to meet them in person, a mybitcoin account or some other service would work better
994 2011-01-11 21:00:35 <luke-jr> including 21mil
995 2011-01-11 21:01:02 <TD> because it can implement brute forcing protection
996 2011-01-11 21:01:07 <TD> whereas a pure block chain based solution can't
997 2011-01-11 21:01:46 <nanotube> djx: what exactly did you do when you 'moved wallet' ? just the wallet.dat? so now you're redownloading the blocks?
998 2011-01-11 21:01:49 <lfm> plus if you both have mybitcoin accounts the transaction can be instantaneous
999 2011-01-11 21:02:11 <luke-jr> yawn
1000 2011-01-11 21:02:15 <luke-jr> so bad example

1002 2011-01-11 21:06:48 <ArtForz> actually if you get your nonstd but owtherwise valid script in a block it IS accepted by everyone
1003 2011-01-11 21:07:21 <ArtForz> network doesnt pass on nonstd TX and normal generators alsdo ignore em
1004 2011-01-11 21:07:38 <ArtForz> but if it's in a block, everyone WILL accept and pass on that block
1005 2011-01-11 21:07:58 <ArtForz> same thing with TX carrying not enough fees

1025 2011-01-11 22:22:08 <mizerydearia> for production environment
1026 2011-01-11 22:22:59 <lfm> if its being patched it might crash

1042 2011-01-11 22:56:26 <midnightmagic> crap i don't know where I sent all my thousands of btc on the testnet..
1043 2011-01-11 22:56:48 <tcatm> midnightmagic: faucet
1044 2011-01-11 22:57:55 <midnightmagic> dangit! i totally had like 26k and i wanted to send it to myself for amusement, so i set up another testnet client and did so. now i don't remember which damn machine was the recipient. :-)

1046 2011-01-11 22:59:37 <cdecker> Has anyone a good understanding about the tx message?
1047 2011-01-11 22:59:55 <cdecker> I'm trying to parse one but I'm hitting my head against the scriptsig.
1048 2011-01-11 22:59:59 <luke-jr> cdecker: I know it's a scripting language!
1049 2011-01-11 23:00:29 <cdecker> Ok, but you could tell me where the script starts or ends in this one http://en.webhex.net/view/682b6b99f783fcf312cae616d878dbc9 do you?
1050 2011-01-11 23:00:54 <luke-jr> nfc
1051 2011-01-11 23:01:02 <luke-jr> well actually
1052 2011-01-11 23:01:10 <luke-jr> I probably could just by looking for the standard script content
1053 2011-01-11 23:01:14 <luke-jr> <.<
1054 2011-01-11 23:01:33 <cdecker> It's the transaction for http://blockexplorer.com/tx/d4a73f51ab7ee7acb4cf0505d1fab34661666c461488e58ec30281e2becd93e2#i565081 AFAIK

1057 2011-01-11 23:06:07 <tcatm> cdecker: Have you already split it into vin/vouts?
1058 2011-01-11 23:06:25 <cdecker> Hm?
1059 2011-01-11 23:06:26 <midnightmagic> i was almost the cause of over 51k of btc in the testnet destroyed.
1060 2011-01-11 23:06:26 <midnightmagic> \o
1061 2011-01-11 23:06:55 <cdecker> What I do is I read the transaction hash of the OutPoint
1062 2011-01-11 23:07:08 <cdecker> Then I read the index (0) which works just fine
1063 2011-01-11 23:07:31 <cdecker> I then read a variable length followed by the string of that length
1064 2011-01-11 23:08:12 <x6763> cdecker: sounds right so far
1065 2011-01-11 23:08:23 <x6763> cdecker: as far as i know...i'm working on this, too, at the moment
1066 2011-01-11 23:08:52 <cdecker> But then I end up reading the count of TxOuts which is 255 meaning I have to read a uint64 which strikes me as impossible
1067 2011-01-11 23:10:45 <x6763> cdecker: are you off by one byte, reading the last byte of the 'sequence' as the TxOut count?
1068 2011-01-11 23:11:00 <cdecker> Let's take a look
1069 2011-01-11 23:11:21 <x6763> that's the last 0xff i see
1070 2011-01-11 23:11:25 <x6763> brb in a few minutes
1071 2011-01-11 23:12:15 <x6763> nevermind, i'm still here for now...expecting someone to stop by for a minute anytime now
1072 2011-01-11 23:13:07 <sipa> midnightmagic: how so?
1073 2011-01-11 23:13:40 <x6763> cdecker: but at the beginning of line 0000D0, you have 0xFF just before 0x02, which is the TxOut count, if i'm looking at this right
1074 2011-01-11 23:13:44 <cdecker> I wasn't reading the sequence, dump me
1075 2011-01-11 23:13:49 <x6763> haha
1076 2011-01-11 23:15:10 <cdecker> Somehow the signature script doesn't look like on BBE
1077 2011-01-11 23:16:15 <cdecker> But now I'm jumping correctly
1078 2011-01-11 23:16:26 <x6763> cdecker: nice
1079 2011-01-11 23:16:44 <cdecker> Well I'll keep on having a few extra bytes in my signature script...
1080 2011-01-11 23:17:47 <cdecker> Can a script really be 25 bytes in length only?
1081 2011-01-11 23:18:22 <x6763> cdecker: apparently both of the TxOut scripts are
1082 2011-01-11 23:18:47 <cdecker> I can't believe it, I got a TX to parse correctly
1083 2011-01-11 23:18:55 <cdecker> Now on to write the unit test :D
1084 2011-01-11 23:19:00 <sipa> cdecker: http://blockexplorer.com/tx/a288fec5559c3f73fd3d93db8e8460562ebfe2fcf04a5114e8d0f2920a6270dc
1085 2011-01-11 23:19:22 <cdecker> Nice one sipa
1086 2011-01-11 23:19:42 <cdecker> But generally they are about 25 bytes long aren't they?
1087 2011-01-11 23:21:02 * kiba is suprised that 80% of bitcoiners are uninterested in space exploration
1088 2011-01-11 23:21:03 <sipa> the default client only generates a few types of scripts
1089 2011-01-11 23:21:35 <cdecker> And since a few versions only accepts the ones he knows about
1090 2011-01-11 23:21:52 <cdecker> Making the whole scripting business quite useless...
1091 2011-01-11 23:22:44 <tcatm> New scripts can be added
