>Honestly, if a 2 week delay wasnt factored in to your purchase decision, you should never have  bought
2 weeks is a good delay. The problem is that they will delay more than that (where are the pics of the PCBs?)

>I find it hard to crucify hashfast over what is so far a very very modest delay, certainly
They are laying to us and buying time. I don't see the future bright in any way.

Did you have Dec 31 in your ToS?

I did.

I think we're done here!   Cool

Except for the whole "US law requiring a refund" thing.  Are you retarded or something?  Illegal terms of sale aren't enforceable.

It doesn't matter if HF delivers in the middle of November like they say, you'll never ROI. It's completely worth it to try for a refund before they deliver. Unless you like burning your money.

The protocol doc is pretty good indeed.

So one HF ASIC actually has 4 dies and will come out of the box @ 422.4 GH/sec (@550MHz), and max overclockable to 537.6 GH/sec (@700 Mhz).

While many will be eager to overclock from the get-go to make up for lost hashing-time, please take note that this will likely void your warranty:

Quote
Modules which are over-clocked will contain logs of such operation, which may void warranty.

Since the KnC 1st batch units seem to be failing all over the place, I for one will probably run my HF unit at the nominal speed for the first week (or two) and monitor the threads for HF units failing before even considering overclocking.

 Roll Eyes  You really should learn the diff between an FTC rule and an actual law before playing Intarnet Lawyar.

There is no rule (much less a law) guaranteeing ASIC purchasers must ROI in BTC by a certain date.

The guaranteed delivery date of Dec 31 is clear as glass and totally unambiguous.

There is nothing illegal in HashFast's terms of sale.

Why don't you give cedivad some Bitcoins to waste on a good lawyer, who will tell you the exact same thing I just did?

Better yet, just send the BTC to me and call it a day!   Cheesy

Finally, there is no motivation to shortening the nonce range in order to drop work time down
to fractions of a second, because HashFast products allow work to be aborted, and in
particular with the GWQ protocol, the OP_WORK_RESTART mechanism provides a built in
command to seamlessly abort all work in progress and replace it with new work based on a
new coin base, as often as required and with negligible hashing downtime

OP_WORK_RESTART = awesome.   The problem with many ASICs and p2pool is that p2pool generates "new" work on a short interval (about 30 sec between reward chain blocks).  Without a OP_WORK_RESTART or something similar an ASIC will continue using "stale" work for a significant fraction of a second (or even multiple seconds).   On Bitcoin network (600 sec average time between blocks) losing say 0.6 seconds to "stale work" means 0.1% stale shares but on p2pool with 30s average it is more like 2% ouch.  This is in addition to other forms of stale shares due to network latency. 

The ability to abort all work rapidly to all cores and supply new work should result in GN doing good things on p2pool.

I see you're in agreement with BFL josh about how refunds work.

And what would be the grounds of this civil suit? A failure to supply the goods that were sold? Doesn't seem so, BFL are churning though their pre-orders, probably about only 25% of the speed they should be, but the bottom line is they are still getting though them. So I am curious as to what is the legal angle here you are claiming? Yes I know in the US you can sue for anything you can possibly think of in your wildest dreams, but lets keep it sensible.

You are correct that BFL is shipping products to customers.  BFL also never made predictions about being ready to ship products to end consumers in October 2012, November 2012, December 2012, January, February (swarm of locusts), March and April.  Those predictions about imminent shipping had no impact at all on potential customers deciding to order units that were time sensitive in their use.  BFL also never advertised a 1/3, 1/3, 1/3 production mix that offered customers ordering that day to get units as they were produced.

Everyone loves a car analogy.  If you ordered a new car from a dealership that took your money on the day of order and then promised delivery within a week, but instead strung out the delivery to many months while the competition started to offer better deals, would you grin and bear it?  The dealership would also make you sign a statement that all sales are final and you just have to be patient and wait.

I don't have an open BFL order and will never make another.  

To take your car analogy further, the dealer offered to refund your purchase price up until the time they actually started to manufacture your car.  So... if you "grin an bear it" you did it of your own volition, since you could easily have walked away at any time. Yes, BFL was late.  I've apologized for that numerous times. But the fact of the matter is, people could have elected to get a refund at any time up until we started to manufacture products in bulk and started to spend the pre-order money on product manufacturing.

How about holding people money against their will - extortion.  How about the millions lost by people as their money was locked up and they could not get a refund to buy ASICS which were shipping at the time.

There are lots of grounds for a civil suit - but it's the criminal I'm after.  And the awesome thing about federal charges and federal courts is that the proof doesn't have to be beyond a shadow of a doubt.  The burden of proof is low enough that I think a conviction is possible for these thieving crooks.

Be that as it may, you're most likely never going to see Josh or Sonny behind bars. They're protected by the corporation.

You neglected to mention the fact that nothing illegal has transpired, either... but, we all know you can't tell the truth and are a consumate liar and troll, so that's not really surprising that you'd leave a relevant fact like that out.

Anyone claiming that HashFast is in the right denying refunds is effectively defending BFL.

Also clear and unambiguous.  If you want to cancel your order before shipment, for any reason, you have the right to do so.

Btw, how much money have you sunk into icedrill Mr. "Always bet on Ice"?  You're just as screwed as everyone else. Why are you people lining up to let HF burn your money? You're the ones getting screwed here.

All you did was fund HF's NRE so that they'll have a source of incredibly cheap ICs to mine with, despite the fact that they knew all along you would never make a profit, while they will make a fortune, just like Yifu and bitsyncom, and of course BFL.

Because I'm not a hashfast customer, I called them on their bullshit pretty much immediately.

Besides, it's hard to see how a lawyer could be a bigger waste of BTC then icedrill.ASIC shares



Always Bet on ICE... indeed.  Hahaha

Operation at 700 Mhz leads to a total hash rate of 537.6 GH/sec, but sustained operation at this level
may run into power distribution or thermal limitations,depending on cooling efficiency.

Operation beyond this clock rate, even if maintained within power and thermal limits, may lead to
degraded hash performance as hash cores start to make mistakes. If attempting to do this, host software
should monitor nonce rates and/or perform periodic testing of cores in order to set performance limits



tl;dr   hey guys our firmware blows, perhaps you can crowdsource something better??

My hashfast contact and I have been working on the cgminer driver for a while for this protocol, and fortunately since they contacted me early, their final protocol is quite different to what they originally had in mind. I'm very pleased with the design overall, and the cgminer driver for it we've been working on will be pushed to a public repository tomorrow.

I think you need to work on your reading comprehension.  Try running any processor at an extreme overclock and the silicon will produce errors.  This has nothing to do with firmware.

Glad to hear it conman.  The protocol is rather impressive a solid +1 for any input you provided.  Nothing like having the guy who wrote the book helping you on the communication layer.

Another testament to HashFast's ongoing efforts to eliminate bottlenecks:  Over 500,000 square feet of assembly floor, capable of three shifts/day burst capacity.



https://hashfast.com/pictures-of-the-ciara-assembly-floor/





CIARA is working exclusively with HashFast.  The competition will have to find another industry-leading goliath with logistic experience second to none.

"Bitcoin enables ordinary people to fight back, to avoid and evade snooping governments, which enact, use and abuse laws that allow them, without due process, to investigate, tax, control and seize privately owned assets."  -   Leon Louw

“We can say without equivocation that firms like MasterCard, Visa and the TBTF banks like JPMorgan and Goldman hate the idea of ever having to compete for business again. They have grown comfortable in their corrupt world of writing laws for themselves without any regulatory oversight. They enjoy the exorbitant privilege of bilking the American economy with extortionary transaction rates. They are scared of Bitcoin. And they should be. It offers transparency, cost efficiency and anonymity.” - Max Kaiser

who knows..  I've had 2 jupiters for 20 days and mined 37.5 BTC,

if I held all the coins until today I would have 50% ROI as cash now but I was selling into the rally so more like 36% ROI as cash so far

had some downtimes and one miner running about 80% until today's FW brought it up to par


YMMV - food for thought - FYI,   etc

I think you're calculating that incorrectly.  If you bought two Jupiters for 58 BTC each, or 116 BTC, and you've mined 37.5 BTC, then your ROI so far is -67%.

I do think KnCs stand a chance of having a USD ROI. At least I hope so since I have one (and paid USD for it, USD I wasn't planning on buying BTC with).  Will they ROI in BTC? I'm not sure. 

Both KnC and Hashfast units might ROI over the long, long term. But KnCs will have a huge head start, hopefully covering most of their initial cost before HF even ships.
