Are you solo-mining through your own pool software or directly to bitcoind?

I tried running solo to bitcoind for a while, but the lack of share activity made me wonder if anything was actually happening.  So I was a coward and stuck with pools.

Uptime becomes a major factor.  If your network is down you are down.  Consider having 2 network connections.  I have that plus a cellular internet connection I can bring on in emergencies.  The same goes for power.  How often does the power go out where you are?  If it goes out will your rigs come back up and hash right away or will they sit idle until you get home?  If your software crashes how long will it be until you know, and can get to your gear to fix them?

Since I outed myself as a large miner in the photos thread, I will tell you a sad story from my start up times.

At the time I was traveling every week, and it turned out that the FPGAs I have were incredibly fussy about USB connections.  There is no way to correct this other than physically power cycling the boards.  Once, shortly after I left from setting up about 30 new boards, half of the existing boards dropped their connections.  Plus one set of 24 boards went offline and I was unable to SSH into the controller computer for them.  It turned out that the new controller computer had a power setting to Hibernate on no activity for 5 hours that I hadn't noticed during setup.

I had a trusted neighbor with my key who I got to stop in a couple days later to restart the computer, but dealing with the other problems were far beyond his skills.

I was out for 2 weeks, and that was before the block reward halving.  I think I lost out on something like 25 coins per day.

It's too bad you don't understand the difference between truth telling and trolling.

Go read my post history and see what I told people last year.  

This is my last post on the subject because the fact is, you are trolling me!

6" vent fans for exhaust.  The big aluminum things are mufflers to cut down on the intake noise and then the boxes are full of packing peanuts to kill the fan noise.

The exhaust provides about 1kW cooling, and then the white box between the shelves is a 4kW portable AC unit (the biggest you can run off a 15A circuit)

Feel free to ignore me. 

My post is on topic and my points about BFL here are as well.

Inaba has acted like a complete ass with me since long before he stopped pretending not to be a BFL employee and I have every right in the world to point out the facts are demonstrating I was right a year ago, and still am.

This is the array of ~140 Cairnsmore CM1 boards I built last summer.  The last time I had all of them hashing on a single pool they were pumping out around 115 GH/s.  Power demand is 6.5 kW, not including cooling.  I've moved them to a better location for summer, which is why I'm comfortable posting now

When I saw Skyfall I laughed at the lame crypto gear the movie's villian had.  



I'd like to give a little shout out of thanks to all the folks at BFL and especially Inaba!  Without you this would never have been as profitable as it is today.  How you might ask?  Well:

• They took millions in preorder money that otherwise would have been spent on hashpower that exists and competes with me off the market for nearly a year now, and continue to do so today
• They scared lots of other folks away from making the investment I did, since it was obviously a money loser when they would ship in October
• They are so unbelievable incompetent, they still haven't shipped!  Meanwhile these babys are chunking out $600 / day
• When they finally do ship, their incompetence means they won't ship much and it will be many, many months before difficulty catches up with my electric bill

All of the above.

Plus you should be a decent electrician, be expert with computers and ideally programming, understand enough about network protocools to configure your routers to give priority to bitcoin traffic, and understand enough thermodynamics to include heating and the required cooling in your profit calculations.  Being a trained HVAC tech wouldn't hurt either.

And I enjoyed the picture.  It brought back the memory of how much I enjoyed writing that story.  I regret a bit that I was not willing at the time to reveal my 'source' was a doctorate in the field and more than a decade working in the industry.

Little scams feeding off big scams.  It's like pirate and... well shit that list is too long to even start.

Aww you read the story I wrote last summer didn't you!


I remember being slammed as a troll back then, and being told BFL was going to ship in October, just you wait!

Roman has been online and replied to another thread in service discussion this week.

Roman  this is your final chance before I open a scammer thread in your and Bitfloors name.  I promise to keep it on the front page of the scammer page until you either resolved your debts or are tagged as a scammer.

1.  Post your plans to repay the coins you lost to your users including a schedule.

2.  Where is the evidence there actually was a theft.  Please post all the police reports, a post mortem of how the theft occurred including transaction events on the blockchain, and any security consultants reports on the event and efforts to mitigate the weaknesses at Bitfloor. (redacted as necessary)

That's a nice reference.

What I'm thinking about costs $5000 / year to subscribe and has a LOT more fabs in it that wikipedia does.

Could be.  IBM used to make mainframe processors that were entire 4" wafers.

6" wafer it looks like.  Probably built in an academic fab.  It's strange that the wafers have flats on 2 sides, that isn't standard.  I have a list of all operating fabs somewhere.  I seem to remember that there isn't anything below 130 nm running on 6" wafers except for an IBM MEMs research facility in Switzerland.

Given the tiny die size, and the large transistor node I find the 2.5 GH/s implication very unlikely.

If someone has some serious photoshop skills it would be interesting to see what all the writing is on the opposite side of the tag.

This dodging capital controls with Bitcoin is going to drive the price to stunning levels.

Imagine you are in Venezuela and you know the currency has to be devalued another 150% shortly.  You have access to foreign currency, but it can be seized by the banks as part of the devaluation.

So you move your liquid wealth into a paper wallet, and wait for the return of a hard local currency.

Rather than deleting posts, which will enable scammers to hide any dissent, a user moderated forum should allow banning of posters.

If a poster is clearly trolling his posts stay, but once banned he can no longer participate.

A list of banned posters for the thread rapidly makes it clear if the thread moderator is using the ban hammer to encourage useful discussion, or create a cult of personality for themselves.

Roman,

When are you going to address the held coins issue?

As a constructive suggestion, I would propose that you offer credits above your fee schedule that transfer held coins into real bitcoins for users who conduct transactions on Bitfloor.

This would help get your liquidity up, and show that you actually intend to make good on your obligations.

Throughout November and December it was impossible to log into SR for 90% of the time.  Check the SR forum history for yourself and you'll find dozens of apologies for DPR for the issues.

I was monitoring it closely out of concern for the potential impact on BTC price.

Now show your data that proves otherwise champ.

Go over the the 'BFL Fucks us Again' thread and read Josh's rant.

That should tell you all you need to know about the professionalism of BFL

This is an array of 18 boards.

Yes, because that completely invalidates the garbage underfill job, and the chipped dies that Greyhawk pointed out.

Keep dreaming my friend.
