Nice update.  Make me want to hold out for my batch 3s.  So wifi is stable for you?  Also, having not opened the case, you are not concerned a bit that the fuse may not be removed yet?

LOL.  I took the cover off, thought "yep, looks like a custom controller" and shut it back up without looking at the fuse.  I could see the 703n, but the other boards were behind lots of cables.  I'm acting like a kid calling his first date.


10:08 PM CDT
I opened it up.  The board is version 1.52.  No additional action taken.

Arrived.  Powered up.  Connected to network.  Hashed away merrily.
Happy!

Updated mining account info.  Previous mining tip to Avalon.
Still Happy!

Off to buy M4 hex wrench.  Just because I want to look inside.


Success!! Congrats ProfMac, it was a long wait.
What's the hashrate? are you going to overclock it?

Everything at the moment is in the rush of unplanned first day exploration.  Woo Hoo!!

I started it with no changes whatsoever.  Then:
0.  I connected my laptop to the wired interface, no router present in the local link.
1.  I added the WiFi network as a client to my CISCO router.
2.  I noticed the Avalon was configured for ozco and eligius.
3.  The eligius worker was the 3rd worker, it was in failover mode.  Both the ozco workers said they were dead, eligius said alive.
4.  I pulled up the Eligius web page and read a little too fast to comprehend enough the first reading.  Decaf.  Breath slowly.  
5.  I have a complicated deal with others that I am going to give payouts to, and an address I am going to pay out from.  I needed to decide whether I will use the payout address from Eligius, or a dedicated address and then make an additional transaction.  Dogie thinks I make everything over-complicated.  This is unfounded.
6.  Both sides of the WiFi are on the 192.168.0.x 255.255.255.0 subnet, so the laptop doesn't see the outside world, and the workstation doesn't see the Avalon.  So I wrote down and typed the account number.  I think I typed the account number wrong.  So by now I've given a nice tip to both Avalon and to Juke-Jr.
7.  I then put it on BTC Guild, because I had an account there.  I had mined the month of February with an NVIDIA card and had 0.008 BTC I couldn't withdraw :-)
8.  The BTC Guild web interface says it is 71,037 MH/s.
9.  BTC Guild says the Avalon's speed is about 69,215 MH/s after 245,404 shares accepted today, and my balance is now 0.2854 BTC.
10.  Each configuration change restarts the uptime clock.  It has been running about 7 hours and probably would have mined productively the whole time if I had been a little more steady at the helm.
11.  Right now, it's in the kitchen with cables running across the floor to the table.
12.  I went to the hardware store and got an M4 wrench and an air conditioner filter to put in front of the air intakes.  The drag on that makes a noticeable difference in the amount of air that exits the case.  
13.  I have not opened the case yet.  I want to do each of several things next:  fix the routing, move it to a permanent location with good ventilation, shut it down and open it up.
14.  Oh, it is running the 20130607 firmware.

15.  I'm sure I'll put the most recent firmware on it.  I may put it in the basement, where it can take advantage of the cool nights, or put it in a top floor bedroom with the exhaust pointed out a window, where it helps to ventilate the whole house.  
16.  I may be a little conservative about overclocking it.  I don't know how conservative.  Perhaps wait until replacement modules are available, or until there are a couple of device-years of operation overclocked without a failure.

For the record, I have had several Chinese students in my classes, and I recognize their communication style.  Based on that experience, I always trusted Yifu, and he has pulled of a major undertaking that is beyond my own ability.  With plenty of time to develop buyer's remorse since February 18, I haven't.

I'm selling two of my Avalons if anyone's interested.

You can point your signature to your auction, and all the posts you have ever made will show the link ...

Your second and third pool are still setup to mine for Avalon.
If 50btc goes down, you will automatically start mining for Avalon...
You should think about changing that, unless you really really really loved waiting for your machine/s.


But it leads to so much delicious misinterpretation that Avalon is secretly mining with unshipped units.

946  Bitcoin / Hardware / Re: [AVALON] - I got my ASIC Thread (Batch #2) on: July 09, 2013, 06:33:49 PM
Doesnt look like the package was stolen, more that you have a wrong tracking id. I read about another customer that got a wrong id too. So maybe youre lucky and get a shipment in next days.

I went to check on my package, and there are two (2 !) different packages with the same tracking id.  Mine and one on the other side of the world.

The ETF haters in this thread are hilarious. Step outside once in a while. Your worldview has become far too narrow.

P.S. No one is forcing you to buy shares, and those capable of securing their own coins will of course prefer to do so (unless its retirement funds they are investing Wink)

No, if anything, the people who think an ETF is a good idea are hilarious. Or, they would be if they weren't so stupid. Why do you need a couple of carnival-head-sized spoiled Winklebrats to buy bitcoins for you? why do you trust them more with your money than you trust yourself? Because they're in the news?  Huh Why would you completely nullify the entire reason of having bitcoins by buying them through an ETF?

Strictly put: You're 'tarded.

If you have $250,000 in your IRA / 401(k) and you can't access it as cash, the ETF is great news because you can invest your wealth into bitcoins.

I'm a senior software engineer and I have been working on computer games and multi-platform development since 1979.

I just really prefer small code bases with minimal dependencies that are compiler and operating system agnostic.

shipped avalon has. anti happy thus.

Never happy anti.  Rules open for him.  Complain always.  76 trombones, he's a clarinet.

951  Bitcoin / Development & Technical Discussion / Re: A bitcoin blockchain parser in a few hundred lines of C++ on: July 06, 2013, 11:54:15 PM

If you are changing the client anyway, then you could just force a difficulty change. 

That is what some coins do after they lose lots of hashing power.

That would let us get back to hashing without forking the chain.  I think a chain fork is a very big step.

952  Bitcoin / Development & Technical Discussion / Re: A bitcoin blockchain parser in a few hundred lines of C++ on: July 06, 2013, 10:28:24 PM
I thought it might be interesting to do some experiments on that block chain, to go back to the next to last block at difficulty 8,000 and produce a fork.  I would attempt to repair the chain to the extent possible.  It should be possible to mine new blocks that honored previous payouts (or possibley not, in the case of the grief-miner)

That is a chain fork, since the new "official" chain would have lower POW.  If you are modifying the client, you could just put a blacklist check for the first high difficulty block.

Presumably, the miner traded his coins before departing?

It is a curse of alt coins that hashing is so variable.

I don't know if he traded them or not.  If he did, I would want to have the miner's block payout to whatever address has coins derived from his.  That will take some analysis, which is how I ended up in this thread.  I have mixed feelings about not replacing his coins.

I also wanted to choose what times-tamps to use on the forked blocks, instead of "now."  I haven't read the client's source.

A long time ago (Feb 18th '13) in a galaxy far far away (Minnesota) Detritus ordered an Avalon.

Today it arrived....


Mine arrived in Minneapolis today.  I am out past Lake Woebegone.  I should receive them Tue., July 9.



How long did you have to wait?  Huh

I surmise that both Detritus's and my units arrived in Minneapolis at the same time.  He got his locally to Minneapolis, mine is taking 4 more days to travel the last 180 miles.

I'm sorry, maybe I should have asked another question - haha.
When did you order yours? Same as him - Feb 2013?


My payment was transaction ID 5268c88176f24dcaae4e862e9ec1ad696a6915a20f1de9a7fe7042ad9b2f3b9b

Simple version:
It is possible at any point in time there are multiple conflicting blockchains.  The "longest"* chain is considered the consensus record.
* longest in this instance doesn't mean just highest block height (as that can be spoofed) it means the chain with highest aggregate difficulty.


I want to produce just such a spool in the bytecoin blockchain.  Someone mined blocks at the rate of 1 every minute or two at difficulty 8,000, and then quit mining when the difficulty climbed to 32,000.  Since that transition to higher difficulty on about May 5 (two months) only about 250 blocks have been mined.  This past week, 1 single block was mined.

I thought it might be interesting to do some experiments on that block chain, to go back to the next to last block at difficulty 8,000 and produce a fork.  I would attempt to repair the chain to the extent possible.  It should be possible to mine new blocks that honored previous payouts (or possibley not, in the case of the grief-miner)

I have a retail TP-Link 703n flashed with the Avalon software.  It is running on my network so I can learn the interface before delivery.

Today I notice a large number of attempts to log in as root from 59.53.94.9
This may be an address in China, no DNS names are returned after the chinatelecom.10gigabitethernet6-1.core1.lax1.he.net hop.



Where did you find the logs for login attempts ?

On the web page. status --> system log

Do you suspect a backdoor or information leakage?

Of course I do.  But I don't think it passes the sanity test.
958  Bitcoin / Development & Technical Discussion / Re: A bitcoin blockchain parser in a few hundred lines of C++ on: July 05, 2013, 06:53:44 PM
Ok, I think I'm making progress understanding this; a bit.

(5) On BlockChain info, if you just look at Block #1 https://blockchain.info/block/00000000839a8e6886ab5951d76f411475428afc90947ee320161bbf18eb6048  It specifies both a hash and a previous block hash.  I'm a little confused on that point; there is no 'previous' block to block #1.  Also, there is no 'hash' field on block-chain data structure; only a previous hash field.


Block #0 exists.  Your link has a field for "Previous Block" on the right hand side.
959  Bitcoin / Hardware / Re: Avalon batch [2] countdown! on: July 05, 2013, 05:32:07 PM
My DHL tracking page says my Avalon traveled from Beijing to Minneapolis in 4 days.
Email from DHL on July 3 said it would be delivered on Friday.
A phone call just now says it is handed off to another carrier for the last 180 miles, and will arrive on Tue, July 9.
I called about a 1/2 hour too late to have DHL hold it in Minneapolis so I could pick it up today.
