00:16 *** zombie67 has joined #boinc

00:16 <zombie67> pov, my electricity cost is  $0.35 per kWh

00:17 <PovAddict> how much does that card eat?

00:17 <zombie67> not sure

00:20 <zombie67> about 300w under full load?

00:22 <PovAddict> dustcoin says $-57.94/mo, heh

00:22 <zombie67> pc mag says 246

00:23 <zombie67> yeah, if one is going to mine, fpga is the future, right?

00:23 <zombie67> or dedicated ASICs?

00:24 *** efc has quit IRC

00:25 *** eagles0513875 has quit IRC

00:25 <PovAddict> afaik, fpga is the past, 65nm asics are the present, 28nm asics are the future

00:25 <PovAddict> but it's still a gamble

00:26 <PovAddict> you pre-order an ASIC, it gets delayed, then gets delayed again, and who knows what happened to the bitcoin price or mining difficulty by the time you receive it

00:27 <zombie67> well sure.  the currenty itself is very risky

00:28 <PovAddict> rumor has it that the cause of the delays is that ASIC manufacturers use their own chips to mine a lot, and finally deliver them to customers when they are still profitable but barely

00:28 <zombie67> hilarious!

00:28 <PovAddict> so the cause of the delay is that they figured they can still mine a few more weeks :P

00:30 <PovAddict> zombie67: this is the latest insanity from BFL http://www.butterflylabs.com/monarch/

00:30 <Romulus> Title: 600 GH/s Bitcoin Mining Card | 28nm Technology | The Monarch (at www.butterflylabs.com)

00:30 <PovAddict> it's more than a thousand times faster than your GPU

00:31 <PovAddict> but it's "pay $4,680 now and get it on january - maybe"

00:34 <PovAddict> if you could get one *now*, it would pay for itself in a week

00:34 <PovAddict> but you can't, who knows what the mining environment will be like in january

00:35 <zombie67> yep

00:36 <PovAddict> http://pastie.org/8282460 this is interesting btw

00:36 <Romulus> Title: #8282460 - Pastie (at pastie.org)

00:39 <zombie67> yeah.  But still, if you can't get to the internet, cash is king.  And internet activities are monitored.  Even if the content is encrypted, they still see the traffic.

00:39 <PovAddict> it won't replace cash

00:41 <PovAddict> also, the anonymity of bitcoin lies just on the fact that you don't know 1PqD4MrVenYtQrnhv37DuEf9wpWxubMtfn is an address I control

00:41 <PovAddict> by design, everyone can see all transactions

00:41 <zombie67> right.  It's not possible to be completely anonymous with bitcoin

00:42 <zombie67> even though some people try to say it can be

00:42 <PovAddict> there's a proposal to improve the anonymity but it's quite... intrusive

00:42 <PovAddict> protocol/code -wise

00:44 <zombie67> there is all kinds of packaging data around all internet traffic,  Nothing can be truely anonymous and still be trusted enough for mony.

00:47 <PovAddict> if you send btc to the address I posted above, no amount of tracing and monitoring will let someone else know it's my address, except of course for the chat message where I mentioned it

00:47 *** eagles0513875 has joined #boinc

00:47 <PovAddict> the problem is if later I want to *send* that to someone else :P

00:50 <zombie67> the bassic with problem with encryption and anonymity.  How do I know that your public key is really you?

00:53 <PovAddict> hm well

00:54 <PovAddict> zombie67: in the case of bitcoin, I wouldn't give you someone else's public key since that'd mean you'd send money to someone else instead of me; but if someone is intercepting the communication and replaced the address with his own, or if I'm not even online and it's someone else using my IRC nickname, then yeah we're screwed

00:55 <zombie67> man in the middle

00:55 <PovAddict> only safe way would be if I send you the bitcoin address in a GPG-signed email with a GPG key that you trust because I exchanged it with you in person :P

00:56 <zombie67> right

00:56 <PovAddict> or (WoT) my key is trusted by someone you trust

00:56 <zombie67> anonymity and security on the internet requires off-internet

00:59 <PovAddict> zombie67: http://xkcd.com/1181/

00:59 <Romulus> Title: xkcd: PGP (at xkcd.com)

00:59 <zombie67> love xkcd

01:00 <zombie67> love his numbers twitter feed

01:02 <PovAddict> oh man, I'm a few posts behind reading what-if

01:03 <zombie67> what-if?  the marvel comic?

01:04 <PovAddict> http://what-if.xkcd.com/

01:04 <Romulus> Title: Signs of Life (at what-if.xkcd.com)

01:05 <zombie67> very slick.  lemme bookmark that.  :0

01:05 <PovAddict> the numbers twitter feed is a side effect of the research for that :)

01:06 <zombie67> oh wait, that is the twitter feed I was talking about

01:06 <PovAddict> eg. from twitter: "1.61: Storage capacity, in petabytes, of a gallon jug of MicroSD cards"

01:07 <PovAddict> that was something he found/calculated while researching for http://what-if.xkcd.com/31/

01:07 <Romulus> Title: FedEx Bandwidth (at what-if.xkcd.com)

01:07 <zombie67> yeah, that one is pretty famous

07:38 <AlexCzar> Hi all! I have a qaestion about boinc and wcg. I had my laptop off for several days and as a result am missing a deadline of one WCG task by 9 hours. The task is still running though, will it's result be taken into account or I should drop it to not waste time?

07:46 *** DrCode has quit IRC

07:48 *** DrCode has joined #boinc

08:10 <microchip_> AlexCzar: the task will be accepted as valid but you won't get any credit for it

08:11 <AlexCzar> microchip_: I really don't care about credit, I care about usefulness. Will it be useful for the project?

08:11 <microchip_> yes

08:11 <AlexCzar> microchip_: thanks, I'll let it run then.\

08:20 <desti> has wcg long tasks? make only sense for very long running tasks, otherwise they are already send and processed by other users
