p.s. since I wasn't talking to cypherdoc, and he thought I was, I can only conclude by his statements that cypherdoc == Hashfast_CL == unpaid.  Got it.

Namecalling adds volumes to your credibility.



Not being paid, isn't the same thing as being an unaffiliated shill with Hashfast in your name.

Aside, logically thinking individuals can clearly see that my post was directed to the company, and Hashfast_CL specifically, not you.  It makes your calling me an idiot that much funnier.  Keep it up.

Whoa!  Stop the press... that sounds like something an end-user would say, not an employee of Hashfast. 

Furthermore...




Hashfast, the company, apparently wasn't fully onboard with this... as evidenced by the subsequent post by Amy Woodward only two hours later:



So, tell us, are you employed by Hashfast?  Will someone from an official Hashfast account confirm that?  If not, you're some form of unaffiliated shill.  Are you cypherdoc?

If you're not officially affiliated with Hashfast, the moderators should change your name.  Hashfast employees, what's the deal?

Now that they've been called out, we'll never know.

Dun dun dun!  It seems we now know what Amy meant by:






That sounds like a good reason for Hashfast to sell individual mining boards only, and let their customers worry about the rest.

I'll go a step further.  Read and re-read the first post:


Notice anything wrong with that?  I do.  "intern"?  I think they mean "in turn".  The whole post looks like it was written by a 7th grader.  Equally concerning...


Perhaps he means "at the moment"?  Maybe English isn't the original poster's strong suit; maybe English is his second language.  Fine, point taken, but....


3rd floor eh?  The internets think this building only has two stories:

So what gives?  Another scam?

You can find a good overview of the hashing algorithm here:

What N4rk0 said above was also good advice; I too found the endian changes a bit hard to grapple.

To the original poster, CAL is interesting, and I can't help but think it might speed things up a few percentage points over Phoenix/phatk.  Will you be open-sourcing your miner?

I can't see that this software would be helpful in the least.  It can't see where NewEgg shows you "OUT OF STOCK" on a particular page because that's generated by JavaScript which it apparently can't parse.  For a good example, pick an out of stock product, add it, then go into the filter wizard and look at the preview.  That's how the program sees the web page, and you won't see the words "OUT OF STOCK" in there, as you would in an actual browser.

So how exactly does this help you?  Does it update the change time by some other criteria?  And what if NewEgg decides to show you a different (or new) product review when the program refreshes the page, does that not constitute a change which would trigger an email notification?

Edit: I see in the "check" tab that you can make it emulate Internet Explorer - maybe you left that part out?

I figured I'd take this up on the forum, as I saw someone ask a similar question on IRC without a plausible answer.  With a MSI 890FXA-GD70 (an AMD 890FX chipset motherboard), the manual says that if you arrange the PCI-E slot utilization according to their printed recipe, the slots will all become x8 instead of some wacky combination of x16, x4 and x0.  So when the system makes all of the slots uniformly x8, what's actually happening?  Are the additional lanes being physically disabled, i.e. you can't use them?  Or are the slots simply being given the equivalent of x8 throughput with the chipset, even though you can still transact information on all 16 lanes?

There is indeed, it's called pushpool.  But it's a real PITA to build.  Once you have it going, it'll log shares to a text file, which you can use to dig out the info you want/need.  You can also make it log shares to the database backend (SQLite, MySQL etc).

It's basically as the OP described - a persistent HTTP connection that is held open until the global blockchain increments.  At that point, the long polling server sends back a getwork response for the new block and closes the connection.  It's fairly easy to get sample data; just fire up Phoenix or poclbm in Linux and run tcpdump.

You do know that there is already a JavaScript miner, right?  If (re?) written properly, it could send AJAX updates back to a webserver which could generate your Flash on the fly, effectively accomplishing exactly the same thing.

I too have had massive problems with Deepbit over the last 24 hours, many miners die after a few minutes, some won't connect at all and are seemingly banned by IP.  I've switched those to Slush permanently; if I encounter any more issues in the short-term i'll just switch them all.

The stale shares you're referring to are because of the aforementioned long-polling issues.  Nobody is sure what makes it work, or not work, through the current codebase.  The best suggestion I can give you is to run something like PHProxy at http://url.of.your.minining.proxy/phproxy/ and edit the code to send out this URL to your miners, rather than trying to use the in-built broken proxying code.  At least I think that'll work, from what I recall of the code and the way that LP works.  If you go this route, report back and let us know how it works out.

As a staunch capitalist, I have to disagree with this union foolishness.  Economics 101:  If someone is selling at $10, someone else is taking the other side, essentially betting that coins will be worth more than $10 in the future.  In fact the aforementioned figure of $22.69 sounds spot-on to me, so let's assume they'll rebound to that, or whatever the equation leads to in the future, accounting for difficulty.  What then is the net effect of this pricing instability?  Quite simply, that kiddie miners who don't approach this like a business (the OP probably does not fall into this category) will scream "oh gnoes the sky is falling!!!111111" and get out of mining.  People this is GOOD NEWS!  Anyone who can't handle a month or two of sub-par Bitcoin valuation should not be in the business of minting, period.  Isn't that what you're all taught in business school - that you should prepare for the possibility of economic downturns lasting for months (if not years)?  Oh what's that you say, they don't hold business classes in mom's basement?  Sorry, my mistake.

At this moment, the same seems to be true of Bitcoin.  That is, it requires new money, perpetually, to make the coins worth the cost of minting them, and to uphold everyone's faith in the system.  Picture my forefathers, some 200 years ago.  They had to start minting the US government's first supply of money, so some guy with a bunch of copper deposits tells the gov he'll go dig up a big chunk of copper in his backyard and break it down into chunks small enough that it can be pressed into pennies.  In exchange, he'll receive a few of these newly minted pennies that he can use to exchange with other people who accept pennies.  [Of course, the reason for such example is that the gov. had no other practical way to confer anything of value to the guy in exchange for his copper and his time, other than their coins.]  So he does as they wish, gets his pennies, pays for some more labor, maybe for more land with copper deposits, etc.  The point of this rather crude parallel is.. if the gov's source of copper dries up, they can't mint any new pennies, thus there aren't enough pennies in circulation to become useful to anyone.  Now that they've lost their utility, their value is gone as well, and people no longer exchange their time and talents for pennies.

Just sayin..

Actually what he asked had to do with ganging up small PSUs in order to make, effectively, one big one.  That's incredibly simple - you need nothing more than a bunch of diodes (albeit, big ones) and a bunch of soldering.  But then what if current-hogging ensues because you didn't know to include components to equalize the voltage between the various PSUs and they start dying right and left?  If the OP doesn't know what a P/N junction is, how a diode works, what forward/reverse bias is, etc., then how would he know how to fix the inevitable problem that pops up when there is one?  How would he know how to fix the design flaw in my aforementioned example, or other unknowns?  As for "fuck all you imma do it anyway", that's what it seemed like.  The question was essentially phrased like.. "I wanna do this, tell me how!"

The encryption used in bitcoins (SHA256) is completely legal in the US.  The National Institute of Standards and Technology, an arm of the US government, has a recorded standard for SHA256. 

No shit.  I was describing this very thing to someone knowledgable in finance, who recently learned of bitcoins (and is now invested heavily).  I told him how bitcoins rose to $9 about 3 weeks ago, then started slipping back to 8, then to 7, stagnated, then slipped even further to like $5.20.  It was all based on miner sentiment apparently, because I was one of the ones who sold off during the slip.  I didn't want all of my effort to be worth $0.  So of course this led me to the conclusion that the market is controlled completely by miners, who are mostly dumb kids with free power in mom's basement or a dorm room, irrationally reinvesting most of their money into mining ("to combat difficulty rises" is the excuse often used), and then irrationally selling off.  While it might've been rational to sell off during the aforementioned slip in the market, the current selloffs are just foolish.  Sadly, the market seems to be dominated by said fools.  *sigh*

I'm pretty sure you are too, but ohms law is hard, let's go shopping for more 6990s.  NOT!
