All thoughtful responses. Thanks.
Here's what I find odd. It's in the details regarding BFL's chips. Someone responded on this point, but I want to highlight it again.
Recap
Shipping delays
BFL implies that bASIC's shipping timeline will be adversely affected by the addition of additional ASIC chips, to 72 GH/s, to the bASIC PCB's.
I think it's fair to say this is true. bASIC will incur partial PCB redesign and without knowing how far along in their PCB design/production process it's unclear how this redesign impacts their schedule.
Being so close to reported shipping dates makes it reasonable to assume the dates will be missed.
On the BFL shipping front BFL_Josh has expanded on the bASIC 72 GH/s development by stating
We will not allow our shipping schedule to be affected by responding to questionable claims from competitors.
BFL insinuates that by responding to bASIC that they would put their shipping schedule in (further) jeopardy.
Here's the rub. Based on BFL's statements the current Single 60 GH/s offering has ASIC chips at 50-60% of their claimed maximum clock rate.
So, BFL increased their ASIC clock rates in the past to address Avalon. No additional ASIC chips, no PCB redesign. What I will assume makes this increase is a firmware tweak.
Why not another ~20% increase from BFL through the same firmware tweak? No shipping impact. To claim otherwise is suspicious - but there may be other factors.

From BFL_Josh at the BFL forum I don't really want to say anything negative about the bASIC at this point... Tom is already apparently in a really bad spot and there is no sense pouring gas on that fire. We haven't decided specifically which way we want to make things even up with competitors products yet, but we have a lot of options and we will match competitors products that actually ship. We will not leave BFL customers behind the curve when it comes to hardware. I'd say there's a good chance we will be shipping before bASIC at this point. Should BFL's customers take this to mean BFL will reserve any competitive action until competitor products are on the market? If so, where would this leave BFL customers who have already taken delivery if BFL does ship first and 72GH/s products are on the market shortly thereafter? IMO, at best, this is a conservative move. At worst, it's a disingenuous ploy to deny competitive pressure. |

The problem when the issuer does not maintain their pseudonymity.
Feels insecure and lawyers up. The liability is def on the part of the issuer.
This is not acceptable with contracts written under pseudonymity. What we are seeing is what happens when the issuer fails to maintain the integrity of their pseudonymous contract. Negligence?

The semi-official Bitcoin Pool Comparison Chart only shows 2 stratum pools, BTCGuild and Slush's. Are there others?
Most pools are in the process of implementing it. Of the other ones that already have it, ozcoin is my favourite, but emc also does it (though with too unstable a variable difficulty IMO). Good to know  Thanks ckolivas  * ckolivas rattles the donation jar and whistles innocently j/k People should start pledging amounts earned from when they receive their new gear. 3.0 btc here. Sure, I'll pledge an unknown amount of my unknown earnings from my unknown gear that I may receive, or not, so the story goes. I'm sure ckolivas and graet can really plan allot for the future based on that.  I'll count my chickens after they hatch and go from there. censored. |

Yeah.
Reading that conjures up ideas such as 'thought police' and orwellian worlds. Eliminating emotion is ...insidious.
Granted I would have liked a better public education. My experience was a zoo-like atmosphere and very disappointing.

Considering that I do homeschool, I have heard of the Singaporean method. I wasn't impressed, myself.
You have to remove your capacity for your children to feel before they can learn properly. We are also #1 in the world for lack of emotions. When asked did you have an smile, laugh, feel angry or sad yesterday, only 36% of Singaporeans report yes. That is the lowest rate of emotion in the world. We even beat out the ex-Communist countries. Your children probably still don't know how to master their emotions. How do you expect them to learn if they are always getting distracted by emotional noise? While the world will demand increasingly productive people the thought of humans as logic machines without feelings to interrupt that pursuit is majorly disturbing. I'm not convinced mastering emotion is lacking emotion. |

^^^^ Re: Long, informative USB stuff Ok, now I get it. Rather than the issues of collisions found in hubbed CSMA like Ethernet USB is multiplexed with the host controller as master. I was worried that USB introduced collisions in the formal sense. That would definitely be a problem for non buffered nonces every 70ms. Ok, I can relax now  edit: I believe FTDI usb/serial chips have advanced driver settings to control payload buffering in the chip. |

Re: USB hubs vs root ports
Typically a vendor will identify a multi port USB PCI-E card as "full bandwidth" to indicate that each port is a root port and not hubbed.
I have seen very few "full bandwidth" cards. Most are hubbed.
By looking at the PCB it's usually easy to spot the hubbed cards. They have a single set of 2 large IC's.

So I'm trying to get my mind around what the best set-up would be for up to 25 ASIC units. Either the BFL SC singles or bASIC.
What about USB bandwith ? Can you use a couple high quality usb hubs or will they have bandwith issues ?
Bandwidth has less to do with it......., since actual bandwidth is quite small, the REAL issue is the protocol. In another post I'd recommended that the Chinese ASIC system could potentially scale better, since they have opted to include WIFI/Ethernet. The problem with USB is that only ONE device can be on the buss at a time AND you have to signal connection & disconnection Which means as the number of devices grows, so does the buss collisions. Hubs solve F*** ALL, the same way that building more roads into a city does, all a hub does is increase the potential for collisions. It is RAW ports that you need, since they decrease the chance of collisions by a power of the number employed. Two RAW ports decrease the collisions by a power of two over the number of devices.(since you can split the USB tree) Overall it is very difficult to work out HOW ASICS will impact the USB communication, because so little details have been released. Consider the Implementation of a SIMPLE buffer scheme for returned nonces. Take the following..... Setup one: Returns EACH nonce when found Setup Two Bundles up nonces and returns a batch every second. consider that we find 5 nonces that are viable, Setup Two will only negotiate with the USB ONCE every second, therefore the collisions are limited down. Setup one will attempt to connect & disconnect ATLEAST 5 TIMES with the USB infrastructure, this will seriously impact the distribution of work to other devices, plus it is going to be exponential for each extra device. Since the Damned ASIC vendors are telling us nothing about how the devices are implemented, we cannot plan ahead or work out anything. HC Agreed. The USB root port PCI-E cards are a little pricey. Might be worth it. |

Who thinks BFL's competitors are due to wither away if they don't quickly go with a 65 or 45nm process?
500 TH+ competitors will have already started to experience sharply declining sales due to 10+ mo ROI.
Difficulty could reach these levels in a year.
Is investing with a BFL competitor more risky without having a roadmap/plan/stated intentions from the competitor? Will vendor paranoia persist leaving the community/customers in the dark regarding future technology plans?

I am not a BFL hater. I just knew they were lying about shipping dates. It was a calculated decision to be the first to suck money from
asic buyers and it worked. Past performance shows they have no problem telling fibs about when a product will be ready to ship. Now I
am not saying they are not building the actual product but they are quite shady when it comes to being honest about time lines which
was done to get the money first. Therefore I have no problem with people disliking BFL. They sorta deserve it at this point.
2013 will be the shipping year for most of the orders. I predict they will squirt out a few before 2012 just to say they shipped in 2012 but
that is about it. They will not ship the hundred and first order until Feb-march.
The effectiveness of marketing schemes that either bend truth or omit truth is based on maturity of the market. I don't see mining as a mature market where miners are treating mining as a business and by that fact less willing to go on faith and more willing to withhold capex until a vendor meets realistic, concrete expectations. No single consumer will have an effect on vendor behavior. Organization, by definition of maturity, of the mining community is necessary and sadly I don't see that happening any time soon. |

Do you see how your threat seems a little overcooked now?
It's not a threat, it's a promise.  And yes, I realize I am only one person, but I have a feeling there are others that feel the same way. It is hard to post your feelings on here, especially on such a controversial subject as BFL, without trolls picking your posts apart. I actually can't even put one single post on here about ANYTHING without someone trying to prove me wrong, calling me names, sarcastic remarks, or arguing with me. So, I'm not surprised there haven't been more people talking about this on here, but I know I am not alone. This is a common problem coming from people with little perspective. Everyone's right and everyone's wrong. It's wonky. |

Would be interesting to know if the modem provides any interface to see what channels are being affected (if any). ADSL2 should shut down channels that have excessive interference.

There is no many coz there are no implementations of any of the crap that you seem to think is better in GBT.
...
So yes GBT sux and no matter how often you make these deceptive comments, GBT is still crap.
GBT just wants to be friends.  |

Nobody here is goin' to fall for that ol' banana-in-the-tailpipe trick. Make it at least $300K, and we'll get off your back.

Ok, Axel. I hope you wrote that with the appropriate manly voice. reference of awesomeness |
