The triangle may be ending by going up. We hovered around 125 support pretty much all weekend, a number of dips into 124, but generally all around 125. Lets see how this unfolds. 

"This problem will persist until no more than 288 blocks after 256818, unless another trigger transaction is added to the blockchain (which may well happen)."
    So.....its is not a fork, and it should be resolved within about 24 hours, the Bitcoin-Qt is not able to be re-opened once you close it and they are patching it. Correct?

This has the potential to have some long term impact on the exchange landscape: https://bitcointalksearch.org/topic/ann-krakencom-exchange-with-usd-eur-gbp-jpy-cad-btc-ltc-xrp-nmc-xdg-str-eth-290799

If the market is looking for a reason to break lower...

Observation: Bitstamp currently has positive money flow while Gox has negative money flow. Interesting because the StochRSI now indicates they are both oversold. It seems Bitstamp is Bullish and Gox is Bearish.  Bitstamps "positive money" flow is larger than Gox's "negative money" flow; Seems like a battle between exchanges and looks like Gox USD volume is about even with Bitstamp atm, so Bitstamp may take the bullish lead. It will be interesting to see which way we go. Could this be a bear trap?

And also to be fair to Deathcode, I should say that I've just had to get up to get my daughter ready for school after only about an hour's sleep, so I'm was just being grumpy anyway, I apologise for that.

What I need is a rally to $1000 to cheer me up, or at least another coffee or a bit more sleep.  Usually I try to be cheerful but my sense of humour doesn't seem to be online yet, I'll go and put the kettle on...

To be fair, what you were asking is totally off topic. It probably got singled out because you're talking about Litecoin and mining, which people in this thread generally particularly aren't fond of talking about.

In other news- I'm hoping this is a slow week.

Nice attitude, hey?  Well you feel free to talk about the walls and all the trading that's happening then, not that there are any to discuss.  Everyone else has been off topic too for this reason too, so why single out what I wrote, hey?

Honestly though I really can't be bothered to argue about this with you, maybe this thread should just be closed down until someone puts up an ask/bid wall to keep you happy as this is officially a single topic thread. (not a thread that you created though and you're not its moderator)

Gas used to be about half the cost of electricity here in the UK too, but in recent years the price has greedily risen a lot more quickly than with electricity so there's not a lot between them these days

Anyway, it'd be a smaller machine that was contributing heat, not a large machine kicking out so much heat that using the boiler was unnecessary.  Well, it was something to idly consider last night, not a project that I'm definitely hell bent on achieving.  I was just thinking about how much it costs to heat my house, it'd be lovely to have a heating system with generated money as well as heat but I suppose it is a bit impractical.  Or to put it another way, if the heat generated is useful then surely this must alter the way LTC mining profitability should be considered re: LTC mined vs electricity consumed because there's the third factor to consider of the waste heat no longer being waste and the fact that this where most of the electricity consumed ends up.  Anyway, the best use for such a mining rig were it possible would be to take it back in time to when Bitcoin was first new and mine back in the days when most people hadn't heard of BTC, and those who had were CPU mining - or better still just use the cash to buy up BTC four years ago - why didn't anyone tell me about BTC back then?

I think everyone is board and the walls around Fort Gox are moving and people are tracking it in real time.

Well gas is about half the cost of electricity when it comes to heating. Im not sure if litecoin gains would outweight it, at least at current costs. I mean, looking back, a 7950 was making something like $20/day at point. If you sold at todays prices. Back then? Pennies?

Similar to that cable, but to plug into a motherboard's PCIe x16 slot at one end, and split into 16 cables with one PCIe x1 adaptor on each of the other ends to connect to 16 graphics cards.  The amount of data needed by each card mining can easily be sent through a single PCIe lane, after all the BFL 7GH/s vapourware miner that I've had on order forever uses a USB lead which is even slower.  (Where's my damned ASIC then, BFL?)

As for efficiency, consider it like any other machine for a moment, forget about data because that's not quantifiable in this way.  The card uses a certain amount of power, say 250W perhaps.  now where does all that power go?  The amount of electricity used by the PCIe interface is very small, the same goes for the video output cable.  This means that the bulk of the power is going somewhere else.  There are only three other ways for the power to go, remember that energy can neither be created nor destroyed, it has to go somewhere.  Those three ways are heat, noise and into kinetic energy from the fan and the air that it moves.  The moving air and the spinning fan will lose their energy as heat from friction in the bearings and against the air in the room, there's no other place for it to go but that's only a small proportion of the energy that the card uses anyway.  The noise isn't like a stereo turned right up (for a single card anyway!) so that can't be using a lot of energy either, and the sound vibrations in the air will also convert into a small amount of heat as the atmosphere in the room or the bricks in the wall absorb them.  This means that almost all the energy goes directly into the heat lost from the GPU itself.  Even the electrical signals absorbed in the motherboard and the monitor will eventually be lost as heat too.  So this effectively means that all the energy that goes into the card becomes heat from one source or another, the only lost energy is from any sound which escapes the building and loses its energy outdoors, which will be negligible.

So, given that virtually all the power used by the card must become heat inside the room, that means that it would produce exactly the same amount of heat as an electric fan heater that used the same amount of power, so it would cost the same amount of money to run it.  The fact that whilst it's heating the room it also generates Litecoin is bonus, and when that's counted against the electricity bill it means that a mining rig is a cheaper way to heat a room than an electric heater is.  Of course though this still leaves the cost of the equipment, which is the only thing which can make it work out more expensive overall, that's why getting the parts cheaply is vital.

Anyway, I like tinkering with electronics so it's something to occupy me during those long winter nights.

Of course though there's still the issue of whether the noise will drive me insane!

I think you mean something like this:

never tried to get one though...

EDIT: Just say you wanted for it to have 16 slots, 4 is the biggest I saw, but perhaps there are bigger...

Your boiler is more efficient as a heater than some GPUs.

Do you mean like this?

What would the purpose be [I mean, its making heat either way?]

Does anyone know if it's possible to buy an adaptor cable which plugs into a motherboard's PCIe x16 slot, which then has 16 PCIe x1 slots attached to it, one PCIe lane each?  I was wondering if it might work out cheaper if in addition to my expensive gas boiler I was to heat my house by Litecoin mining.  Almost all the power used by the GPUs is lost as heat, but in winter heat is something I want and something I would have to pay for anyway.  This would in effect be a noisy and bulky fan heater which generated both heat and money, the heat would make up for the fact that LTC mining uses a bit more electricity than the value of the LTC it mines.

Every calorie of heat the mining machine blows out is a calorie my boiler doesn't have to produce.  Obviously there's the component costs too, those would have to be second hand, such as old HD5870s which work fairly well but aren't very expensive any more.

Maybe I could find a way to create such a cable if they're not commercially available
