Please explain the low div...

The COG.F and COG.F2 contracts were converted to COG shares, and the bulk of the CT hardware has not shipped yet. When the hardware comes online we will see a large increase in our dividends.

Also, Sam and I are currently working on an inventory spreadsheet which will be released tonight.

Best,
Garrett

Looks like a decent amount of shares listed.

I take it we don't really have Hashfast units?

So our total div for the week was 1.183 or 2.366 if you count the 50% held for reinvestment? So far I have seen a average of 6ths hashing which would produce that by itself in about 2-3 days. What about scrypt hardware did that not produce anything this week? What about the nearly 1th we had before this equipment show up? Why is the div less than half of last week when there was less than 5000 shares added? Why are all of these things still problems every week? I invested in this company over a year ago when your communication was much better along with you following through with commitments and getting things done when you say you will. I would like to see cognitive return to that status.

In the meantime Garrett started intensive studies and is probably struggling in a relationship...

If you haven't yet seen the new Cognitive Inventory spreadsheet, it can be viewed here:

https://docs.google.com/spreadsheet/pub?key=0AgfcX1i_jmKIdDJiRnJTWHlQUWtweEVYOC1XeEN3cEE&output=html

Yes, unfortunately Cognitive does not own HashFast units. I apologize for this mix-up.

According to the spreadsheet, we currently have 18.5 TH/s of hardware "arrived", but looking at eligius, it looks like a lot of it isn't working reliably yet.

I think the goal this week has to be to get those things having reasonable uptime, whatever it takes, or to hold CT responsible for delivering working units.

Current diff is 3.815bil.  18.5 TH/s should make:

1.0/(3.815*1000*1000*1000*(2**32)/(18.5*1000*1000*1000*1000)/(60*60*24))*(25) => 2.439 BTC/day => 17.1BTC/week * 50% => 0.000628 BTC div

Our actual div was only 0.000087, about 14% of expectations.  Presumably due to hardware unreliability.

Depending on how fast we receive hardware, we should expect next weeks' div to be OVER 0.0006 and if we receive all of our hardware, it could be as high as:

1.0/(3.815*1000*1000*1000*(2**32)/(31.5*1000*1000*1000*1000)/(60*60*24))*(25)*7*0.5/13595 => 0.00107 BTC/share


TL;DR: projections for next week's divs are 0.0006 to 0.0012 depending on luck, hardware arrival, and hardware reliability.  If hardware continues to be this unreliable, however, we could see divs under 0.0006 and it'd be *very* bad for us.

EDIT: I misread the div by a factor of ten *facepalm* *fixed*

Cognitive-PR, you may want to remove the two links in the footer of www.cognitivemining.com.  One is MtGox, which is rumored to be having problems of some sort, and the other is to bitbank.me, which appears to have expired and is now owned by a domain squatter.

Guybrush01, thanks for the suggestion! The links have been removed.


Suggestion:

It would be helpful to tag the miners in the Eligius Pool to be able to track the status of each miner worker.  By appending "_name_of_system" to the end of the 1cogxXyYU2EXEbdcV9j18PWenRU7gAjt1 address for the username, each miner can be tracked separately.  Could help troubleshooting which miner has an issue by checking Eligius stats as well.

Here is an example - http://eligius.st/~wizkid057/newstats/userstats.php/1LxYXZpBaGTV11qFAy8DP2rHneBNRmQZ4s
By tagging the username, it shows the "Toggle Display of Worker Details"

djjacket, this is excellent input. Garrett is going to set up this sort of system as soon as he can.


According to the spreadsheet there is 10THs or so is there a problem with some of the equipment?

Yes, some of the units have faulty firmware, and have been shutting off when power cycles. Garrett is currently in negotiations with CoinTerra regarding this problem, so hopefully they will compensate Cognitive for this loss in hash power.

This is one thing Garr has done right in his dealings with CT so far.  Please keep holding them responsible as far as our contract can (and ensure future contracts more clearly protect us against late/defective units).  If cointerra isn't planning on dumping a pile of shovels on us then disapearing - if they want to be in the long-term shovel selling business - then they actually care about their reputation and want us to be happy.  Let's hope anyways...

Where has our scrypt hardware been mining? It seems we have been averaging under 2ths with our asics, what is being done about this? The first 2 weeks of owning hardware are the most profitable and our hardware has been offline more than on. Is there going to be further explanation on the dividend? For example why was it so much less than the week before? Yes the company grew by around 40% in terms of shares issued because of the conversion. But the div from the week before was for around 2 days of running the equipment was it not? This week we had even more equipment with Garrs claim that he had manage to fix some of the units and we had it all week long. Yet the dividend was less that half of the previous div. Thank you

I get the sense that the hardware is not monitored, in the sense there is no one physically near it so that if it goes down it then stays down for a long time, until someone can get back to fiddle with it. At least that's what it looks like from the heartbreaking Eligius chart.

a) Is that true?

b) If so, can that be changed? Ideally things would run reliably on their own, but since they rarely do, it seems silly to let 6-8Th/s of gear just lie around doing nothing most of the time. Right now we're a mining farm that doesn't mine.

Peta-Mine is a larger operation, but they're also running mostly Cointerra machines and their graph is very different than ours.

How about deploying remotely managed power distribution units?  If it is a problem where the hardware hangs but works after a reboot, maybe being able to remotely powercycle the unut would be helpful.

The only problem here is they can be quite pricey. It will be more practical to remotely soft-reboot, then if that doesn't work remotely upload firmware again.

You are absolutely correct here. I have spoken with Ravi many times and it is very clear to me he is in this for the long-haul, and is all about creating and maintaining good relationships.

12 hour hashrate is currently at 2TH/s still =(  Can you give us an idea of what it takes to make a malfunctioning unit function (i.e. 1. powercycle, 30 seconds 2. re-flash, 5 minutes, 3. run mining software 30 seconds - this is just an example, but what I would like to see)?

Is there really only a single unit functioning reliably right now?  are none of the units functioning properly but one is up "on average"?  Is cointerra doing something about this or are we expected to add automatic redundancy ourselves?

I am officially offering my technical services as a programmer, free of charge, to help out however I can.  I think I already PM'd my phone number, but in case I haven't, PM me to arrange communications if there is anything I can do to help.
