I man form far Russian region Ural. Mining bitcoin and other cryptocurrencies about two years, now my small mining farm has 4 GH.
My main work is gas distribution service, engineering of computers and telemetry. Hobby also about computers and electronics - I collect old calculation machines and early PC from junkstores and try to revive it, sometimes successfully.
I member of FIDONet since 1996 - old computer professionals may remember that "noncommercial worldwide network". My node 2:5080/205 still alive and not so long was the celebration of our network's 2:5080 21-st anniversary.

I am paradoxically pleased to hear that a FidoNet node is still active.

guys, i am not willing to change anything in the machine except the absolutely necessary,
IP,pools and thats it. No firmware update not anything else. very rare and delicate equipment to play with Cheesy

Good point as long there are no problems and it works:)
I know i have to do exactly same thing but..I will mod it for sure - cooling, 3g, 8M flash
I am wondering if power supply is strong enough to handle overclock to 300?

as long as it says 600W-235V on the wall clocked at 282 it means that PSU output is something like 600x0.8 is 480 Wats. I know that it is 650 Wats PSU output but i am wandering how power consummation increases when clocked at 300? It may become something like 550 W in tottal which might be too high for the PSU? I am a kindind of person who prefers to have spare Wats especially speaking of PSU. If you have noticed Bitcoin foundation unit has 1100 Wats PSu for 4 Asics - 850W should be more that enough.
Ngzhang can you comment that when you have time of course. Shall all of us be worried about penitential Power issues when clocked to 300 with Stock 650W PSU?

Oh i forgot i will drill a couple of tiny holes for sure just on top of PSu to let some of the hot air to come out instead going into the box. The holes must be tiny because they will not destroy aluminum and it will be still able to work as a heat sink



I don't like the idea of metal filings falling into my power supply.  Especially aluminum filings.

Too many chemicals Sad Im trying to do it with simple chems like alcohol ect


The secret is, chemists who know what they are doing focus a lot of expertise and effort to do it as simply as it can be done, and still work.
If you try to do it simpler than a consultant tells you to, something will go very wrong.

So all I do is get the tea boil it for a few mins put baking soda and dry? thats it?

caffine pills? cocaine?

Just like developing your own film is more expensive than taking it to the photoshop, extracting your own caffeine is more expensive than just buying it.  When I have 30 students do this extraction, it probably takes $100 in consumables, and $500 or more in lab space, plus 150 hours of (their) labor.  The total yield for the entire class is probably only 300 mg.

If I count their labor at $8/hr, the cost per gram would come out to be about $6,000 / gram.  I am pretty sure you could get paid to remove bucket fulls of it from any commercial coffee producer.



No.  There will be lots of tannins, the brown colors.  There will be much more of them than caffeine.  Google has some of the Pavia book, but a couple of pages are missing.  Any nearby college library should have a copy of this book.

Take tea leaves, place in hot water, wait a couple of minutes, remove tea leaves. You know have hot water full of caffeine.

But you want to put baking soda into the extract to get all of the caffeine out.  The tea will not taste good, but the goal is to get the caffeine, not drink the tea.

where do i get dichloromethane?


This should be changed to a greener solvent.
1430  Economy / Services / Re: How to extract Caffeine from TEA ect? on: March 14, 2013, 06:35:26 PM
No im trying to extract caffeine just for fun and to have it

better buy decaffeinated tea?

This is a standard lab for 1st semester organic chemistry.  Go to your local college and buy a copy of "Pavia."

An ordinary teabag will yield between 0 and 10 mg of caffeine, depending on your skill.  I think the Pavia book uses dichloromethane in one of the steps, and this should be changed to a greener solvent.

I suspect it would be just as easy in a home environment to put the tea into an evacuated home canning jar, and deposit the caffein on the lid using dry ice to cool the lid.  I have not, however, attempted this.

1431  Bitcoin / Mining / Replace [BTC] 25 per block, dust of time on: March 13, 2013, 07:43:21 PM
The miner reward has dropped from BTC50 to BTC25 per mined block.  This was planned from the beginning, and it will drop again.

If the value of BTC doubles, this is ok.
If the value of the transaction fees increases to fill the void, this is ok.
If miners make less money, this is ok, but does put an edge on my mining aspirations.

I am assuming that it is consistent with the original program design that some transactions, which I will call dross in this posting, are left behind:  when the Pullman is full, there are no free loads.

Some people may feel urgency to have their transactions confirmed.  The original model allows for variable auxiliary payments, which I will call bids in this posting, and unfortunately named fees, to expedite confirmation.

As a complete noob, I went to Daily Bitcoins, the site that gives  BTC 0.00005 to look at an ad.  I authorized BTC 0 transaction fee to pay out my new precious, and the transaction did not confirm until 4 AM.  I repeated this for 3 or 4 days, then moved on to a verified account, connections with my bank, and a more solid connection to the Bitcoin community.
--------
I find myself fascinated by the SD dust conversation.  I have read much this week, and my thoughts are slowly forming into an opinion.

It seems to me that having more transactions than space in the block is a wonderful situation for Bitcoin.  There is clearly demand.  For the moment, a noobie can try a zero fee transaction, go to the rest of his life, return in a day or so and explore his transaction on Blockchain without begging or being forced to pay or abandon his exploration.  When I was moving real money on a bank holiday to a special auditing address for my Avalon purchase and time seemed precious, I had the easy option to pony up my bid and make it so.

I did grow up in a part of the country where anything in any way connected with gambling, sexuality, tobacco, alcohol, or excessive recreation was severely censored and suppressed.  I still carry the legacy of that upbringing, and I cannot envision myself building a business in those areas.  I find the values clarification conflict between neutral currency and judgement of SD or Silk Road to cause me some discomfort.  I do wish they did not exist during those times I want to explain Bitcoin to people in my day life, but nonetheless, they do exist.

Nonetheless, I think that the existence of a full pay load for every block is healthy, provided that the miners are common carriers.  I think that everyone who grew up in Dallas will ultimately decide that same thing, regardless of the nature of that pay load.  I think that competition is healthy, and I think that a defining characteristic of competition is the possibility of loss.  In this case, it is the loss of inclusion in the currently block.  Without that possibility of loss of priority, it is not actually competition, it is rather theft of services by the customer.

My prescription at the moment is:
Keep the blocksize at the 0.7 level, but move to 0.8 in order to remove the problematic BDB code. 
Distribute the configuration recommendations that make the 0.7 & 0.8 outputs remain compatible.
Segregate the SD transactions into two categories of blocks, those that exclude them, and blocks that are only them, when it does not violate any other rule or custom.

That is all.  Miigwech bizindawiyeg.

Continuing to experience a "halting problem" on my Avalon ASIC miner:

The miner stops mining, fans stop spinning, but cgminer is alive and responding to API queries.

Thank you for a factual, clinically dispassionate report.

Cumulative Fees Paid:        2837.93797500 BTC

What's wrong with the fees paid? Those all went to miners.
           small (bets < 4 BTC) |  3522656

What's wrong is they're spamming the chain with microtransactions with minimal fees causing a lot of dust that will bloat the chain. It's not healthy.
"minimal" fees, which just so happens to follow the rules when it comes to transactions and the inclusion of fees... if you don't like the "minimal" fees on small transactions, then lobby to get the fees changed on small transactions... _ALL_ small transactions... don't just go targetting SD specifically. They are just following the system in place.

Any of you guys connecting to a wifi router? It would be a mess to lay a cable and I think this would be too noisy for the bedroom, shall I finally get one.
yes, take TP-link MR3420 very nice and cheap (openwrt)

A brief Google search takes me to their web page, where it is all marketing speak but no information on how much storage (RAM, Flash, whatever) is on-board.
It may be time to move beyond my DL-524 :-)
I want to be able to use openwrt or dd-wrt.

1435  Bitcoin / Bitcoin Discussion / Re: Alert: chain fork caused by pre-0.8 clients dealing badly with large blocks on: March 12, 2013, 04:45:12 PM
So, can we all agree that rushing things to take care of the volume of transactions that are mostly comprised of satoshidice spam isn't a good idea and it's SD who needs to change and not bitcoin?
Nope.

I'm not saying it shouldn't be fixed. Just saying that rushing fixes isn't the way to go, as can be seen from this major fuckup.


Is there a link to "the best" thread to place the future SD impact discussion?

why the hell is Deepbit only on 0.3.21 and Luke on 0.6.0?
I would like to ask this question as well.

Your bug icon is very disturbing.  I have finally trained myself not to try to squash it.
1437  Bitcoin / Bitcoin Discussion / Re: Alert: chain fork caused by pre-0.8 clients dealing badly with large blocks on: March 12, 2013, 04:01:42 AM
why the hell is Deepbit only on 0.3.21
Tycho has been very resistent to any change.

... and Luke on 0.6.0?
Eligius is actually running both 0.6.0 and 0.8.0 concurrently, but has 0.6.0 prioritized so it trumps 0.8.0 when there's a conflict.
It noticed and began reporting the problem immediately, but I guess wizkid057 was busy with something at the time.

I love this guy.

Luke -- perhaps this is a good strategy for miners to adopt. Perhaps someone should pay you (the Foundation?) to keep running like this to catch bugs quickly.

What do you call a spymaster who spies on his own spies?
Prudent.

Oh dear.

After this I switched to Bitstamp using my online handle name and setup Google Authenticator. I then had my phone stolen last week. They are now asking for ID to disable the Google Auth, which of course I don't have since the name I signed up with doesn't exist...

 it's not a small balance and it's in dollars, not BTC.

That's just plain stupid. Why did you set up google authenticator without a paper backup? Just ALWAYS print out the code/qr code that you import into your google authenticator app. Or take a screenshot, encrypt it and back it up digitally.

Otherwise, you can't complain if you loose access forever. I mean: phones get lost and stolen a lot, don't they?

Go to a notary public with your identity and residence documents.  Fill out a statement that the phone was stolen, and have it notarized.
Include a bank account under the same name.
Scan all the documents and send them in, and ask for a release of funds to the bank account.
1439  Bitcoin / Bitcoin Discussion / Re: Why does everyone keep calling them fees? They're not fees, they're BIDS! on: March 11, 2013, 06:14:36 PM
If they were called bids, then I would assume that I could increase my bid at any time - which would actually be pretty cool. If I'm not seeing my 0.0005 BTC "bid" getting through in 30 minutes or so and I'm getting kind of frustrated, I could double or triple my bid to increase the likelihood of it going through in the next few minutes.

Create a double spend transaction with the same inputs and outputs, but a different "confirmation urgency bid"
Currently most clients in the network will block/not relay this second transaction though.
And rightly so.  If clients relayed double-spend transactions, it would make 0-conf transactions (which are used in things like digital download services) utterly useless.

However, I'd like to think that a particular set of rules could be created to allow relay of transactions with the same inputs and outputs, but it wouldn't be easy.  The possibility of additional inputs in light of a higher fee has to be considered, as well as a differing change address or a differing amount going to the change address.

Perhaps changing the bid after the fact is not the correct approach.

Is there enough information under control of the Satoshi reference client -- what do we call this, just bitcoind, SRC, or what --- to predict how many blocks later the transaction will be processed, based on work already in the queue?
Not at all, because each mining pool has different rules by which they include or disclude transactions.  And if higher-priority transactions are created at any time while the transaction is waiting, they take precedence.  There isn't any sort of queue, only priority.  Any sort of estimate wouldn't be at all reliable.

A different question comes to mind.  Is there any interest in a product that lists the top n pending transactions sorted by their transaction fees?
