Indeed.  Derpinheimer, can you please tell me where I can trade my USD for any other currency besides bitcoin and pay just 1%?  And don't tell me forex, I want to actually take possession.

I understand how raid works. I clone my OS and backup my data on a extra drive.

So my avalon would be more efficient if i stopped using wifi and plugged them in to my desktop with ethernet? Not quite understanding this.

Network shouldn't make that much of a difference.

Please read the guide I linked above.  It explains what you need to know about how p2pool works.  And I'm sorry I offended you by warning you about raid 0.  I'm glad you have good backup policies.  You'd be surprised how many people do things to improve performance without understanding the tradeoffs.

So does HD speed with PSpool matter or not? Why would it? Avalon is not connected to my desktop its using wifi.

Im using samsung pro SSD in raid 0.

SSDs in raid 0 would work fantastically, but I hope you know that with RAID 0 if any of the drives go down, you lose all your data.

HD speed does matter because with p2pool you have to actually run a complete bitcoin node and that node has to create the work for your miner.

Good thing there's so many bears here, or else we wouldn't enough panic buyers for later. Permabull season has only just begun.

There's so much positive news right now.

http://thegenesisblock.com/mt-gox-withdrawal-freeze-driving-significant-liquidity-concerns/

I notice they don't mention that the withdrawal freeze is over and has been for 7 days before they published the article.


"Upon the completion of the two weeks, the company announced the end of the hiatus, though a significant back-log of withdrawals would mean at least another two weeks of delays."

You caught me.  I didn't read it carefully because old news is old.

This looks very odd. Did you find the issue yet?

No.  And the B.E. LED gives a good, bright light which toggles off and on then stays on after the R.Pi is up and running.  The lines thru the test aren't mine but appeared when I copied and pasted.

When I try to run it on a Ubuntu system, and this has been running bfgminer with a zTex 1.15x, I get 'unable to enumerate USB device on port'.

The lines are because the forum uses
Code:
[s]struck text[/s]
for strikethrough.... like this: struck text

Try wrapping what you pasted in code tags.  This will prevent the forum software from attempting to interpret anything within the tags.

A bit of a Medusa at the moment, but I'll clean it up later:

what did you use to build the rack? I was considering legos, but i like yours. I'd just want to add clearance for my fans.

K'nex... I've been building with them since I was 8 Smiley.  Much better for structures than legos.

Interesting, thanks for the tip. This is why i ask questions. Do you know why P2pool doesnt work well with avalons?

P2Pool mines against your local Bitcoind and that doesn't supply work to an Avalon fast enough.  My local Bitcoin-QT client doesn't even supply work to a Block Erupter fast enough.

You need faster disks.  I'm running 61 USB block erupters (equivalent chips to 2 BE blades) on p2pool with getblocktemplate latencies below 0.1 seconds and an overall efficiency of 111% (I earn 11% more because my node is faster than other nodes).

How fast of a disk do I need?  I have a 1TB SATA drive.

I think you put your finger on it for me though, your using GBT and I'm using getwork to my client so that probably makes a huge difference.
Sam

So you're not using p2pool, yet running around making claims it won't work? Roll Eyes

The guide I linked above recommends SSD drives.  Personally, I'm using a RAID 10 array of 7200 RPM disks.  The size of the disk doesn't have much to do with it's speed.  What matters for this application is the RPMs since you need very fast seek times (which is why SSDs work well, they never have seek delays).
1989  Bitcoin / Pools / Re: Question About Pooled Mining on: July 12, 2013, 05:31:58 PM
Right, if it takes 1 terrahash to find the right nonce, as far as the bitcoin network is concerned, 1 terrahash - 1 hash of that work can be thrown away.  However, the pools track a lower difficulty "share" and use those shares to calculate a payout when a pool member finds a block.

What about Eligius? Claims to be 0% fee and with 'shelved' shares approached zero fee PPS.
I hear people dont like PPS no more.


You need faster disks.  
What are disks?

Hard drives.  To run a p2pool node (or any bitcoind based mining setup), you need either a SSD drive or a RAID array if you want to stick with spinning disks.

Check out this guide if you are interested in a positive p2pool experience: https://bitcointalk.org/index.php?topic=153232.0

We see a very high dead cat bounce right now. Its just a question of time to drop off.

BTW you can win my avalon for only 1 BTC Shocked (raffle)!

I really doubt you'll find 250 people who are willing to gamble that much.... but this is bitcoin.  Honestly, I'm surprised you have 9 already.
1994  Bitcoin / Development & Technical Discussion / Re: What Bitcoin Could Learn From Gnutella (or, why devs need a spanking) on: July 12, 2013, 04:57:31 PM
Just renaming things doesn't change the executable, AFAIK, in a release build. So I would globally, with a careful global search and replace, acknowledging each replacement, names that are obviously too terse, obscure or no longer even representative of what they are, with more meaningful names.

Is there software tools for verifying equivalence ?

Quote
I propose that style of renaming, rearranging, etc. that leaves the executable, byte for byte identical.

That would do it.  However, presumably, object code would have variable names.  Is the linker deterministic, I wonder.

Hash maps could end up in a different state if different keys are used (assuming the compiler sometimes iterates).

You can easily strip debugging symbols and just leave offsets/pointers.  The linker should be deterministic as long as you don't update any libraries in between.  It really depends on your compiler and language.  I know there are C compilers that will produce identical binaries regardless of var name, but I'm less sure about C++.

It is the short share time combined with the high latency of that particular hardware.  The new version will extend the share time from 10 to 30 seconds, which should make Avalons (and other ASICs) perform decently.  But before the change can happen, we need to have 95% of the hashing power on the new codebase.  At that point, the share chain will hardfork and p2pool will be ASIC heaven.  Could be today, could be 2 weeks.  It all depends on people upgrading or new users joining up with the latest version.

Oh, and my parents are fools when it comes to money.

Did they buy Bitcoin?  Tongue

They don't get it, and they've been burnt too many times in the "real" economy to trust anything with a hint of risk.
1997  Economy / Speculation / Re: Myself chart thread :D :D on: July 12, 2013, 04:09:56 PM

Yes.  I was 13 in 1999.  I had earned and saved $1000 and my parents took me to their stock broker.  She had me put half in CSCO and half in ORCL.  What a fucking waste of money.

Oh well, it was a good lesson to learn at that age.  Fuck brokers, they try to sell their firm's bad positions off to you.  Oh, and my parents are fools when it comes to money.

western civilization is also a bubble.

How can I short it?

1.  Borrow Europeans and North Americans.
2.  Sell them.

2000  Bitcoin / Bitcoin Discussion / Re: ASICMINER BE, has enough area, if covered with solar panel, to power itself? on: July 12, 2013, 06:53:45 AM
Sorry, I should have mentioned USB variation.
Asicminer block errupter USB.

2.5 W

You would still need a panel larger than the USB, but a smallish panel could power it.  Roughly 1/10 of a roof panel.
