You'll still be relying on some third party outside of the bitcoin network itself though. Not very different from the way credit transactions work now, but isn't one of the advantages of Bitcoin that it could be different and have the fast confirmations built into the system itself?
282  Bitcoin / Bitcoin Discussion / Re: How to verify a person's DOB without private information on: July 24, 2012, 09:24:18 AM
Degrees of trust. The amount of trust a random internet comment/user garners is really low. Heck, not everyone trusts government verification of various things but it's trusted by more people and to a greater degree than a random statement. Which is why security clearance stuff does a lot of multiple verification methods. Let me know if you figure out how to engender trust while remaining anonymous, seems like a difficult challenge.

Internal transfers of coins on a service is the current "quick" solution, but wouldn't it be great if the built in confirmation (say basic 6+ confirms) process could occur very quickly. It is an internet currency after all.

Will be interesting once all the block rewards are mined and the network is persisting on transaction fees alone.

Yeah, Pico seems to be good at pushing PR and perhaps their support is top notch (only their customers know) but their hardware markup is very high.

It's a multi-rail PSU, so you probably just overdrew on a rail. Need to distribute power to keep under each rails Amp rating.

What specific model of power supply?
288  Bitcoin / Bitcoin Discussion / Re: Bitcoinica MtGox account compromised on: July 19, 2012, 05:40:35 PM
Well, the compromise of funds before finalization of the agreement would help get the Consultancy guys off the hook assuming they hadn't taken over day to day operations when it occurred. I have the impression though that they had a strong enough belief that they could recover from the incident going forward. Otherwise it would have been better to deal with the legal hassles of a failed ownership change than to take on the business.

Although, if Tihan's control of Intersango shares was of a nature to allow him to stymie development of that project, it would have been an effective stick.
289  Bitcoin / Bitcoin Discussion / Re: Class action Litigation vs. Bitcoinica Consultancy LTD & Intersango LTD on: July 19, 2012, 04:23:04 PM
With the new admitted loss of claim funds the odds of getting any non-lawyer driven satisfactory conclusion is slim to none. Continuing to spend money of an insolvent company is a very poor decision, really they should be voluntarily contacting the relevant NZ bodies to wind down the company.

BTW, this is an example of where the "let out the magic smoke" joke came from in regards to dead computers and their components. Way back in the 80s and 90s the electrical components were more massive used more material so you could actually get some smoke spewing off shorted equipment.
291  Other / CPU/GPU Bitcoin mining hardware / Re: 6990 caught on fire... on: July 19, 2012, 03:39:58 PM
Flames mean a sealed component bursting, if you are dead set on playing with it I'd be doing it on a system I could afford to lose.
292  Other / CPU/GPU Bitcoin mining hardware / Re: 6990 caught on fire... on: July 19, 2012, 03:35:28 PM
Sounds like an electrical short of some sort. Extender might be possible if it shorted multiple PCI-E lanes. You should be able to visually spot that kind of issue if you inspect the extender carefully. Otherwise I'd suspect moisture damage unless you were overvolting or it was regularly run very hot.
293  Other / CPU/GPU Bitcoin mining hardware / Re: How come the Mining hardware comparison page is not updated recently? on: July 18, 2012, 03:52:35 PM
Yes the lack of 7950 results is due to fewer miners with them and none of the ones with them have contributed to the wiki.

I completely understand that it will take some time to get an actual police report, in no way did I mean release proof immediately. IMO, when you can get a copy post it on the BTCSYN forum and a link to the post here.

Hearing how closely you were working with Enterpoint I can see why you felt confident swapping hardware out. Shame they were not able to accept your payment in bitcoins in a reasonable timeframe.
295  Bitcoin / Hardware / Re: BFL ASIC is bogus on: July 18, 2012, 07:31:40 AM
28nm is not realistic at all, 130nm down to 65nm is most likely by far.
296  Other / CPU/GPU Bitcoin mining hardware / Re: How come the Mining hardware comparison page is not updated recently? on: July 18, 2012, 05:13:31 AM
There are current GPU and FPGAs listed. The Radeon 79xx series is listed as PCIe 2.0 for some reason instead of 3.0.
297  Bitcoin / Hardware / Re: BFL ASIC is bogus on: July 18, 2012, 05:03:47 AM
Block size is actually 512 bit so it's basically 1.51 Gbps / 1024 or 1.47 MH/s
Also power goes up in a non-linear fashion as die size and clockspeed increase.

Another thing that makes the BFL announcement rather
hard to believe is the very large performance increase
they claim to be able to achieve on an ASIC as compared
to the existing FPGA solutions.

I'd have expected maybe a x3 improvement on - say - the
MH/s/Watts numbers, but the numbers they've announced
are hard to stomach.

I would love for someone really knowledgeable on this topic
(how much more efficient can a chip be made when moving
from FPGA from full custom ASIC).

Someone has actually already made a chip capable of SHA-256 on an IBM 130nm process:
http://rijndael.ece.vt.edu/sha3/chip/sha3-asic-datasheet.pdf
If I understand the paper correctly, it does 2.95 MH/s (1.51 Gbps / 256 bit / 2) (divided by two because it's double-SHA-256) while consuming 5 mW (0.005 W) running at 50 MHz. So that's about 3 GH/s at 5 W on a 130nm process.

Here's more info: http://rijndael.ece.vt.edu/sha3/sha3chip.html

I hold a few shares of BTCSYN, was looking at the old motions and then wondering at the recent buy/sell activity. Funnily, I wasn't too happy with the liquidate current FPGAs motion when I read it. Turns out that is the source of the stolen funds. May I ask what the reasoning was behind that move? The Cairnsmore1 devices don't even have a full working bitstream yet. Yes I know you can't rewind, but the whole maneuver there is a bit puzzling without some explanation of the reasoning involved.

Glasswalker continuing to work to make BTCSYN whole (by this I mean continuing to operate with the reduced resources) and also posting a copy of the police report in a timely fashion (blacking out anything sensitive) would help reduce the fallout from this.

Well, they were due for some socket flipping. The AM2->AM2+->AM3->AM3+ progression has been pretty good to piecemeal upgraders.
