BitChick, you think she says childish things now?

Wait till she starts saying "To da moon!"

Wait...

What can I say?  She's blonde.

Who?

Your wife or your daughter?

If the USA wants to be the biggest Bitcoin owner to influence the price seizing coins is a better strategy than buying them Wink

now what do they do?

back over $200!

If I give you BTC.01 for chores and you hold for a year it could be worth BTC.1 or even BTC1 someday!   Grin  I guess it could teach some delayed gratification.  

I think "alien money" will be much more exciting when she needs to buy her first car or is going to college and we have enough to pay for it then!  

thats true and there is something magical about watching your balance increase.

My bad.  0. 01 BTC cannot be worth .1BTC.  What I meant to say is 0.1BTC is worth $1000  Grin

it's ok.  you're a girl.

my wife counts the same way.  the more we spend on sales, the more we make! Grin

Did you forget that Bitcoin isn't anonymous? Kinda defeats the point of Tor to de-anonymise it...
Couldn't coinjoin be built in? And if that wasn't good enough people could mine to have access to the anonymous Internet. Or just buy BTC in person with cash.

or maybe recruit/pay miners to be Tor nodes? 

there seem to be plenty of them around all over the world.  if you mine to protect the Bitcoin network, then you probably wouldn't mind being paid BTC to be a high speed anonymous Tor node.  it would be unlikely for a gov't to be a Tor node AND mine BTC to protect the Bitcoin network. 

seem to be mutually exclusive.

just got mine.

what a brilliant design.   very happy.

can't wait for the gold and silver versions of this same design.

congratulations.

what's the best way to cool down a 10x9 room with all these hashing units in it?

ac, fan enabled high airflow, or a combination of both?  don't forget these chips respond to cool air by self oc'ing which is what i want.

i've priced out the specs doing it by ac alone and it is expensive.  the amount of kW of heat is enormous on calculation.  there's gotta be an easier way.  i live in an inclement area with pretty standard 72 degrees most of the year with some heat during summer.

What is your peak summer time temp.

Assumming you can get enough forced airflow it is ALWAYS going to be cheaper than AC.  AC at best is going to be 3:1 COP in real world.  That means to remove 3KW of heat is going to require another 1KW of AC power.   Using forced airflow a COP of 6:1, 8:1, even 10:1 is possible.   

However we are talking some serious airflow.  Do you have the ability to cut holes in walls, preferably a large intake hole and exhaust hole on opposite walls with the ASIC racks in between?



avg August high is 74

the door has an ordinary vent screen maybe 18x12". 

i'm thinking of installing a large attic fan in the ceiling out to the roof.

I wonder how much work it would be to integrate bitcoin or would it have to be completely done from scratch?

what you have to start with is improving the speed and efficiency of Tor.

then somehow incentivize Tor nodes with Bitcoin traffic payments.  the faster the node the more they get paid.  how you screen out gov't nodes i have no idea.

the point is i would gladly pay Bitcoin to use a high speed anonymous Tor network.

the good news is there's roof right above the ceiling and a sliding glass door out to a balcony for some flexibility.

since the life of the systems doesn't have to be that long, you may not have to worry that much about humidity so give some thought to using large amounts of ambient air as an intake and exhaust the hot air out the roof.  if you can get enough airflow from the outside...  you may only need the a/c to supplement the cooling in the warmer months...

and the life of these systems will start in the middle of winter, and by the time the height of summer rolls around in 8-9 months, their value may not be so much that you wouldn't consider selling them and buying the next generation gear anyway...

that's the way i'm intuitively leaning as well.

damn.  clarification on the airflow direction from the psu's for the Sierras.

D&T is correct, the Seasonics intake air from the sides and exhaust out the back.  i swear Simon told me the opposite.  oh well.

cypherdoc -

its also possible that hashfast has special ordered versions of the seasonic psus that have the airflow reversed...

no, i just heard back from him right now.  but i swear i heard the opposite from him earlier.  no matter.

Imagine TOR but optimized to be high speed as the whole network runs with BTC integrated. Bandwidth costs BTC using micro-transactions. Abuse of the network costs money/resources and the network is compensated in a free market fashion. Technologies like bitcoin are integrated, proof of work, and proof of storage, etc are all integrated. People would run Bitcoin-TOR like nodes to make a little bit of money while users enjoy high speed.

What makes it the killer app? People who want to surf anonymously AND have high speed will now have to get BTC to enjoy it! It will make a market that requires people to get bitcoin since such a thing is not available any other way.

this indeed would be killer.

given the inflated money supply we have experienced over the last 5 yrs, i'm sad to say that "a million" is considered chump change nowadays.

if you have a "quadrillion" now that's saying something.
7879  Bitcoin / Bitcoin Discussion / Re: The default response should be 2.1 quadrillion units... on: October 27, 2013, 02:54:55 PM
It's not a lie.

I'm defining Satoshi units. It's a more palatable number for the uninitiated.
