141  Bitcoin / Mining / Re: What is the deal with Pulse / Magnetic generators? (Free electricity) on: June 15, 2013, 05:30:13 AM
That particular link is not correct. There are plenty of ways to make "free energy" but that isn't one of them.

As the story goes, this video was released after a patent was filed... http://www.youtube.com/watch?v=PFGiWiXMHn0 --- inventor promptly vanished never to be heard from again.
And here's a replica that took 6 years to build based on the first video and the patent for the that one.  http://www.youtube.com/watch?v=fqJDrFMqGlU

This concept involves using magnetic repulsion (and tactical blocking of the leading edge of the field) to make it spin until it either accelerates to the point where the bearings wear out... it shakes itself apart or the magnets literally fall apart and turn to dust from the field interactions. It works well enough, but the cost effectiveness of it is iffy at best (the general assumption is that parts wear out too quickly to make enough return before you have to stop it and replace parts).

~

There's a very interesting coil arrangement called a rodin coil (or star drive coil or starship coil) the interesting effect is that at certain places inside the fields generated by the coil there is enough incidental flux to power diode (or any uni-directional circuit) wirelessly - with no additional loss to the process already going on in the coil. There are literally dozens of people who've made the coils and simply drop handfuls of leds into the flux areas and watch them light up... while monitoring the draws across the coil and showing no loss.

AFAIK there's no serious research into making any sort of generator chain using this tech... I believe the primary issue is that you'd have to be willing to move huge amount of amperage through the coils at some point to produce this wierd effect... and the sheer cost of the materials gets prohibitive rather quickly.

~

There's plenty of people making DIY solar powered stirling engines (using focusing plexiglass to heat the hot side of a stirling piston) - that work even in extremely cold environments... as of yet - no computer controlled consumer products on the market. It's all done with a human focusing the lenses.

~

There's something called a tesla-cable-generator... (yes it's an old tesla patent) that describes how running many meters of insulated cable can harvest current from the em field of the earth - the only reason it hasn't been developed commercially is because of lawsuits where power companies went after citizens using them claiming they were using induction to steal electricity from the lines... Since then everyone's pretty much left it alone.

~

And my personal favorite... Browns gas generators. There's one commercial product that will turn distilled water into browns gas (it's an unstable molecular reconfiguration of HOH into HHO) hydrogen is aproximately 250 times more explosive than gasoline - and browns gas is aproximately 3500 times more explosive than hydrogen. I know one guy in particular that uses a modified browns gas welder running off house current to power a steam engine to charge the batteries that run his house. Seems like a lot of work to me... but man it's cool.

I don't know of any commercial internal combustion engines that are designed to run purely off uncompressed hydrogen... but it's conceivable that it would be possible to design such... and that if you could build one to run browns gas instead you'd see massive amounts of 'free energy'

~

Ultimately when it comes right down to it... the cheap and easy free energy is solar and hydro. You can build it yourself and it's pretty reliable. Hydro is of course best (but requires running water) - solar is climate (and time of day specific) but the stirling engine running off focused sunlight may ultimately make even low light or bad light capable of making good reliable power.




142  Bitcoin / Mining / Re: New FinCEN regulations afecting US hosting for miners? on: June 15, 2013, 01:29:10 AM
Well I read it - then printed it and read it again while marking it up for clarity.

Just couple of things I noticed:

Anyone who solo-mines isn't an administrator (but is a user).

Anyone who purchased a bitcoin then uses to to buy a good or service is a 'money transmitter'

Anyone who does escrow service is a 'money transmitter'

Mining pool ops are going to be administrators (although in the case of bitcoin the definition might fail because they are unable to remove/destroy currency once it's created).

~

To me this looks like setting up to fine the average bitcoin user who buys bitcoin off an exchange up for fines once they spend the bitcoin... along with attacking the pool ops in the same way when they allow miner to withdraw bitcoin.

~

I wonder what affect mining over tor would actually have on the network.

Actually - you may not need to release the source to the general public. Why not bring a couple of other developers in and just trust them with the source. I for example would be all about adding a framework for adding multiple exchanges and building an arbitrage mode into the trader.

The other thing you could do potentially do is turn this software into a pay over time subscription based online engine. Maybe the risk would seem less if they had to deposit to an account on a server instead of having unknown code running on their personal machine. Granted you'd have a huge overhead in securing the site and associated costs... but it might be one direction to go.
145  Bitcoin / Mining speculation / Re: Post if your GPUs still profitable to operate? on: June 14, 2013, 08:24:36 PM
I just liquidated my GPUs - now I'm trying to decide if I should hold BTC or buy overpriced acisminers.

146  Bitcoin / Hardware / Re: I am Getting a miner! Which one... on: June 13, 2013, 11:39:35 PM
You need to wait.

Right now bitcoin mining is 'go big or go home'

There are a couple of exceptions to this:

1. Go BFL if you already have enough of an income from mining to be able to make a series of orders from now until BFL ships on a regular schedule (1 per week, 2 per month, etc...)
2. Go USB (be) If you need to replace existing gpus to kill your electric consumption, @2btc you recoup the costs from not paying electric bills quite quickly. And get to profit-take from gpu sales.
3. Go best mh/$/J If you just don't care and want to make fractions of a bitcoin as a very long term investment... then it doesn't really matter what you get assuming you never spend earnings for decades or longer.

In the case of #3 - it doesn't really matter when it's delivered only that it is - at some point delivered.

~

Personally I'd think long and hard about how much money I'd want to invest long term into mining, then setup a buy schedule. If you can devote enough fiat every month to place an order and do that indefinately - eventually you'll grow an income stream for yourself from all the mining hardware. If on the other hand you can't devote money over time in this way, you should probably just buy and hold bitcoin - then sell it later when it's worth more.

Granted... at least voltage tests and i/o tests seem simple enough...  but on the other hand, if they're capable of excluding defective engines through an automated process onboard - then there's really little reason to pre-test anything.

Well, there is the mater of an expensive test socket/interface to be designed and procured. And did you note they have not even selected their foundry yet. In another post I noted the over-optimism of ASIC customers (ie KNCMiner in this context vs foundries), that was 20 years ago. Seems nothing has changed. There will be tears.

I'm inclined to agree... but you know every once in awhile someone wins 64btc playing satoshidice. So I guess we'll just wait and see.
148  Bitcoin / Hardware / Re: BitcoinOrama Report on the KnCminer/OrSoC Open-day Mon 10/06/13 (Stockholm) on: June 13, 2013, 11:15:26 PM
So you're saying it's more-or-less OK to throw money at these people ?

I'd take it with a grain of salt. Consider who the OP is. That being said: I'm hopeful that knc turns out to both legit and capable, and as with all asic manufacturers once something ships I'll buy one.




What does that mean?! I'm strictly not telling anyone to do anything, at all. It even says that in the first post in no uncertain terms. I then repeated it in a reply to this very question.

I'm just reporting what I saw, as I saw it, and what was said. I'm also making sure the two are separate from each-other so I do not pollute the latter with any opinion. Ask anyone else who attended of their opinion. It will be positive, but Bitcoin's SP, the hashrate, and the known/unknown competition are all factors that have huge influence...on any potential outcome.

KnC/ORSoC are a real engineering firm. There is still genuine risk. Being engineers they are limiting where possible, but the time factor means they have to take calculated risks themselves. Anyone getting into this 'ASIC race', which is exactly what it is, should understand that.

As for my authenticity I turned up knackered after a long convoluted journey with one of the world's worst airline at 6am to the furthest Stockholm airport, and a long-ass coach transfer, in person, after limited sleep throughout the weekend prior, verifiable by all those in attendance. If you want, I'll post the boarding passes as well (sans identifiable personal details).

I believe you where there... but everything else aside - it could still be a con of some sort. If it is, it's best presented one in bitcoin history. If it's not, I'll be buying right along with everyone else once we see product in the wild.
149  Bitcoin / Hardware / Re: BitcoinOrama Report on the KnCminer/OrSoC Open-day Mon 10/06/13 (Stockholm) on: June 13, 2013, 11:12:42 PM
I'll repeat this here ...

My takeaway from that ...

There is no wafer test.

There is no packaged chip test.

They are simply going to solder the chips on the boards and hope any defects are not fatal (ie unusable boards).

Their yield had better be pretty good for that strategy to work.

 (Disclosure, my first job in ASIC industry: test engineer, though things may well have come on a bit in the last 30 years). (Ignore, argument from authority).

PS What is so difficult about the packaged chip test? At the very least measure the supply current to exclude the meltdown risks and run just a few test vectors through them to check the I/O protocol works. They are in way too much of a hurry to get product shipped.

PPS "The chip manufacturer I believe is chosen today. Sam was quite matter of fact about how they aim to hit September,"
... nothing more needs to be said. Read it and weep.

Granted... at least voltage tests and i/o tests seem simple enough...  but on the other hand, if they're capable of excluding defective engines through an automated process onboard - then there's really little reason to pre-test anything.
150  Economy / Scam Accusations / Re: CanadianGuy - self admitted scammer on: June 13, 2013, 11:03:50 PM
Honestly the trust system is a deeply flawed idea in the first place. Tags mean nothing given the proclivities of the people handing out the tags... For legitimate business transactions... either use escrow or accept payment in bitcoins upfront. Simple and no risk. Personally I'm about through with accepting escrow. For the simple reason that it makes what could be a simple 1 day process as a seller turn into at least a week (or more) of waiting around for everyone to do their part.

I just multiply difficulty by 10 for calculations.

That's interesting - I check at 50m 100m and 150m - maybe I'll just start taking a zero on the end instead.

156  Other / CPU/GPU Bitcoin mining hardware / Re: How to select a 7950? on: June 12, 2013, 05:48:43 PM
So I recently bought a selection of 7950s... and ended up returning most of them... except for a pair which I kept (and another pair which I've since sold, because I missed the return date).

The one's I kept were the vapor-x from sapphire absolutely the best card out there.

HIS w/ iceQ is the close runner up.

reference is 3rd best.

Gigabyte is ok... but don't expect to mine with them in a case. These guys need aftermarket cooling on the backside or extender cables so they don't cook whatever happens to be near them.

avoid everything else unless you're planning on watercooling.




This is the kind of stuff you can't learn from a spreadsheet hardware comparison.. thanks.

Was it mostly disappointing hash rates that disqualified the other cards?

Pretty much that and some of the cards seem very touchy about clock or voltage changes. Having everything locked down to the point where you can't even slow the memory down annoys me. =P
157  Bitcoin / Hardware / Re: Block Erupter USB Sales on: June 12, 2013, 05:44:02 PM
It makes sense to replace existing owned GPUs with these on a hashrate basis Especially if you've hit roi on the gpus. The idea is sell the existing gpus while he prices are still good... take some portion of that profit and replace the lost hash rate with 1% of the power draw and almost none of the side costs. So while I wouldn't suggest new fiat buy these things... It does make some sense in the case I've described.

As for me: I just sold 6 of my oldest (and least profitable) video cards as well as a pair of 7950s. Allowing me to then sell most of the parts from the 2 machines that were running them... got a couple of nice 24 port usb hubs and enough of these to replace the lost hash rate... and still make ~1000 usd.

So net gain for me is 1000 usd + ~250 per month savings on electric costs. I don't particularly care that I overpaid from the perspective of 'new money'.
And transit time for the new miners to be delivered... just a few days.

You are mistakenly assuming these things will hold value. They will not. Once the difficulty rises a few more times, these things are going to be worthless. And, with the added bonus of it not being possible to use them for anything else, the resale value will become 0.

With GPU's, you can always get a relatively nice portion of resale value.
You are mistakenly assuming that I care if they hold value. I do not. Once the difficulty rises a few more times, these things are going are to be sitting there mining - I won't shut them off until they become unprofitable (which will be just before the next halving if btc price doesn't go up and difficulty does). I don't care about reselling them.

My point is they'll have paid for themselves in saved power costs within a couple of month and are effectively free to purchase in that sense.

158  Alternate cryptocurrencies / Altcoin Discussion / Re: Moving forward from this dead-end on: June 12, 2013, 08:05:17 AM
Per my prior post, Proof-of-Consensus is a dead-end.

We could still look to improve critical flaws in Bitcoin while employing a Proof-of-Work system:

  • Eliminate the 10 min delay by offering the option for spender to place some funds in escrow as a guarantee against double-spend, and escrowed money is forfeited to the ether if there is a double-spend.
  • Eliminate Bitcoin's declining debasement schedule so there is funding from minting forever
  • Add tx fees to incentivize peers to include more transactions in their TBs
  • Consider a Litecoin-like Proof-of-Work that disfavors ASICs
  • Improve anonymity as we discussed in this thread

I am liking my domain name autonomoney.com because the greatest thing about decentralized currency is that no centralized authority controls who can become a spender and a merchant and there is instant signup with no approvals needed.

We need minting so any one can go earn some coins with capital while sidestepping anti-money laundering laws. We need that minting to not stop in 2034 when the 78 cycle predicts this current global crisis to bottom.

I'm fairly sure you wouldn't be able to eliminate it entirely. But I would expect once the network hash rate grows past some point we'll see an increase in block generation rate (and a reduction in block rewards to match) and also an increase in number of transactions per second.

I believe that making it non-deflationary isn't an improvement that anyone will want... that's bitcoins primary strength. If we eliminate that we no longer need to mess with tx fees.

Changing the proof of work to be asic hostile should be a non-starter, it's doomed to failure by it's very design. Nobody can design any digital process that cannot be accelerated by application specific processes. If you fix the proof of work process then someone is able to design an fpga or asic to follow that process. It might be possible to design some sort of rotating proof of work system that cycles through creating variants of different types of proof of work in an attempt to delay the development of specific hardware. But then again it probably wouldn't be cost effective... as adoption grew the people wishing to profit from creating such hardware would rapidly outpace whatever development work you could afford to do on the proof of work.

There are ways to improve anonymity working on and off the blockchain currently.

Quote from: Wikipedia
Education in Turkey is governed by a national system which was established in accordance with the Atatürk Reforms after the Turkish War of Independence. It is a state supervised system designed to produce a skillful professional class for the social and economic institutes of the nation.

With this in mind, it's almost guaranteed they're all just pissed off and have no idea what they really want out of it, aside from showing a whole lot of discontent.

Except that "Ataturk" was an extreme secularist and the current government has "islamic roots". So what the education system thought to people older than 20-25 is in complete contradiction to the point of view of the current government.

However the current government is successful economically. And they are not really "islamists". They are more like the Christian democrats in Europe, I guess.

So, while I agree, there is some twist.

If it isn't a protest against islam then it needs to become that. It would really be the best thing for the region. The best thing for Turkey would be overthrow of the current government and a return to something secular... combined with the EU pulling prospective status over it.
