Begging for a car is lame.

That's a much better reason. Here you go:

Decent cost. I'm sure interested people would like some more info:

1. How secure is the facility?
2. How many amps can the facility pull?
3. Is there any cooling? What are the inside temperatures like in the peak summer hours?

With even just 150 sq feet, that's a lot of rigs, amps, and heat. Can you handle it?

You want more than $200 for a card worth less than $100? Good luck.
4364  Economy / Economics / Re: We're printing too many bitcoins on: August 06, 2011, 08:51:43 AM
The number of coins mined currently exceeds the demand for them...   that's my concern.
Correction. The number of coins *sold*, not the number mined. There is a very big difference between the two.
4365  Bitcoin / Mining / Re: All Miners Should Determine their 'Break Even' BTC Price on: August 03, 2011, 05:29:08 PM
My best rig is 4x5830, 1080 mhps, drawing 650 watts.

Monthly electricity costs (~$.40/kwh) = $187
Monthly bitcoin income = 17.5 BTC
Break even at $10.7 per BTC.

Yup, I'm already at break even. So roughly, if difficulty goes to 2,000,00 and price stays at $10, then either I move out of California or shut down my rigs.

Are you kidding me? You are limiting passwords to 12 characters? And you consider this sufficient security? Sounds to me like you're storing the passwords in plaintext.
No, it's encrypted.. and B:  we were thinking that people might one day want to use it for their mobile phones...  so I have no idea what kind of phone you use.. but I'd rather not type in a 30 character password.
Really? Because you don't want to type in a long password on your state-of-the-art Motorola RAZR, you are putting every customer's account at risk. Keep your own password at 'abcdef', but don't prevent the rest of us from entering real passwords.

Everything is encrypted with high grade encryption, salted.. etc etc..  Comodo "green bar" SSL, firewalled...  We had it audited by a bank auditing company.  It exceeds banking compliance standards. The main site is just a standard http .. the banking area (on a differing server cluster) goes to the secure system.

and then I found this from the signup page...

password must be 6-12 characters

The costs and profits detailed above are correct, except the electricity draw for each 4x HD 5870 machine would be about 900 W.
Where are you getting 5870's, and how much are you paying for them?

Bought this one, ended up getting my whole base system with a nice 3x full pcie for only 240 dollars =)
With only 4 pci-e connectors, how do you think you'll power 3 cards?

See first post. You'll have to wait a day now:

I strongly urge you guys to get an invite now for flexcoin because when the invite system is off we're going to stop accepting new registrations for roughly a day.
Don't you think something other than a 404 page would make sense?
4371  Bitcoin / Bitcoin Discussion / Re: TradeHill - Dwolla is being scammed and reversing transactions on: July 29, 2011, 09:47:37 PM
I didn't see under what conditions Paxum can reverse charges. They should mention that. Mr. Paxum are you listening?
Yes, that would be good to know.

Certainly if someone compromises the bank or Paxum account, I suspect Paxum will block, maybe reverse transactions. While perhaps unlike, what are the circumstances and procedures?
I sure hope not. The next time MtGox publishes their password database, and some hacker finds my Paxum password is the same, Paxum has no need to reverse any transactions. I screwed up and it's my fault, not theirs. And yes, I'm speaking from experience. I did lose quite a bit of money due to the previous MtGox database.

I wonder if there would be interested in adding a 'conserve bandwidth' flag to the client.
How to limit your bandwidth to 1mbps up and down without bloating up the bitcoin client with unnecessary code:

sudo apt-get install wondershaper
sudo wondershaper eth0 1024 1024

Your pricing was a bit hard to read, so I kind of colored it up a bit.

Pretty colors, but, the numbers are way off.
4375  Bitcoin / Project Development / Re: POLL: Would you use a mining-only datacenter facility? on: July 26, 2011, 04:08:57 AM
I am considering partnering with someone who has funds, renting some office space, retrofitting it with whatever electrical and cooling is necessary for a small datacenter, and renting
out server "slots", for people who can no longer host their rigs in their apartments/houses/basements.
Is a "slot" a 4U spot?

The service would track electricity usage, and would charge a base rate per rig + actual electric usage each month.  If mining became somewhat unprofitable for a week or two, you could simply turn it off, and only be charged the base rate for that period.
What amperage circuits would be provided? Does each slot get a 20 amp circuit? What is the temperature control of the facility?

You wouldn't have remote control of the power directly, so in the even of a hard lockup or shut down, we would provide a "request power on" button in a web interface.  Your rig would be powered back on within 24 hours.  For this reason, it is imperative that you already have a stable configuration prior to shipping to our facility.
But I could install my own remote-power device, correct?

All management of your mining rig(s) would be done by you.  We wouldn't touch it.  You would be responsible for remotely accessing your server, once we unpackage it and start it up, to get the mining running.  You would also be responsible for your own software security.  Given that many machines would be on the same network, you should set up a software firewall appropriately to isolate your rig(s) from the other rigs.
Will you install video cards? Rigs shipped with heavy video cards installed are likely to be damaged by the shipping companies.

You really should enforce separate rig networks, otherwise customers could interfere with each others, like with incorrect networking settings, either through mistakes or on purpose.

Also, do you see any potential problems that I have not addressed?  Any potential security or performance issues?
What is the length of contract for a slot? Do you guarantee uptime (network, electricity, etc) of the facility?
4376  Economy / Services / Re: [100 Ghps] "Catch 22 removal" service for new pool operators on: July 20, 2011, 11:52:08 PM
Kudos to Vladimir for thinking up an innovative way to jump start a pool. It is creative.

I'm not trying to insult Vladimir, but his service make little sense. He is demanding special treatment (no fee PPS + 10% extra + paid for stales) just because he has a lot of hash rate. If a pool offered that to regular miners, everyone will be joining the pool in a heartbeat (who doesn't want 110% PPS?).
Exactly. I'd join in half a heartbeat.

one person pointed out this is more "stealthy" than just paying people to join
That was my thinking. Vladimir would basically be a shill.

Last and final bump... Using the latest kernel at http://forum.bitcoin.org/index.php?topic=25860.0 at stock 6990 settings I get 352 mhps vs hdminer's 354. Hdminer is obsolete. End of thread.
4378  Bitcoin / Mining / Re: Collapse in mining interest could lead to the end of btc in an unexpected way on: July 18, 2011, 05:40:04 PM
Given that most of the btc mining is for profit, the same thing might happen to btc if we see something severely affecting miners. If we lose 80% of our mining network for some reason it could take up to 10 weeks for the next difficulty adjustment. If the remaining miners then pull out since all that hard hashing isn't worth it, it would take much, much, much longer.
If if if. If a pink dragon flew by my house and dropped a load of dung on my miner I wouldn't get any more blocks either.

Blocks/hour    6.23 / 578 s

The reality is the bitcoin network is still growing.

6990 x2 (you can get up to 835 MH PER CARD)
http://www.newegg.com/Product/Product.aspx?Item=N82E16814161366R&cm_re=6990-_-14-161-366R-_-Product
I'm selling each as a pack. I'm willing to let the two 6990s go for $410 each ($820 total) which will include shipping.
This is too good to be true. Those cards go for double that price on eBay.

I really wonder however, how you manage to have THIS many hardware failures?!
Sounds like someone is buying old used parts off eBay and charging the investors for new parts. Is there any auditing of invoices, or is everyone just expected to have faith?
