Would friedcat help seize the shares that TradeFortress is trying to steal from his BTCINVEST investors and at least start diverting dividends elsewhere?

Greetings Eligius miners!

So, I was up yesterday morning at 5:30AM local time (Saturday!) because of one of my "pool is broken" alarms.  Turns out some insanely huge botnet has decided to call Eligius home, and is adding bots at a rate of about 2-3 unique IPs per second.  And of course, these bots are connecting on port 8337 (getwork/GBT).

So, of course, after building up for a while, the server got bogged down and tripped my alarm.  I've since been trying to figure out a solution to the problem, and it is now just about 27 hours later (I had about a 90 minute nap somewhere in there).

Anyway, after many many attempts at different methods for fixing this, I ended up coming up with a solution which basically amounts to load balancing port 8337.  I've also moved stratum (port 3334) to it's own independent process.

Now, eloipool wasn't really designed to do this, so, I don't know if there are any unforeseen issues with the way I've attempted this.  One side effect comes to mind, and it involves variable difficulty calculation for miners who mine from multiple IPs.  Most likely their vardiff number will be lower than it normally would be because of this if they use GBT/getwork because they wont be getting/submitting work to the same server on the backend.  Not a huge problem.  One which I will solve soon.

Edit: I also just realized that this setup affects vardiff for anyone with hashpower on both GBT/getwork and stratum.

So, conclusion, the pool is up, its handling the new traffic now, and all should be well for miners. Cheesy

-wk

Have you considered what happens to variable difficulty when multiple miners are using the same IP and the same payment address. For example one public IP is used for three miners behind a router and firewall but they have varying hash rates (180, 90, 70000) requiring difficulty 1, 1, and 64, respectively? This appears to be a problem even when using the new addresses for getwork for the first two and stratum for the third - where the slow miners usually end up getting difficulty set far too high and the fast miner occasionally has difficulty set too low. The same appeared to happen more than one miner used the new stratum address.

Anyone with a successful removal of fuse F1, yet?

Yes, I removed it from my Avalon and all appears to be working again. The fuse would not pop completely off the pads but enough of it has been removed to open the circuit. It was more of a cut than a removal. A better soldering station might have helped.

Had you noticed any overheating of the NEC usb hub chip?

There were no signs of damage from heat and the Avalon has been stable before and after the mod was performed. The component temperature was not measured.

Btclvr,
are you, were you using wifi ?

Yes, wifi was and still is enabled and working.

Just completed a large escrow with John for 2 Avalons.

He's been absolutely fantastic from beginning to end and had to hold the funds for over a month.

Thanks John...


I confirm the escrow with John and uhoh.
First Asic escrow for John (but not last I suppose)!

Thanks John, thanks uhoh

John did an excellent job escrowing a 3rd Avalon from uhoh that I purchased. It completed shortly after the transaction with pixel75.

Thanks to John and uhoh.

Why does the 24- or 48-hour low for G.ASICMINER-PT in the BitFunder Market page reflect lows that do not show up in the transaction history and that are well below the top bids?

At the moment the 48-hour low was 0.95 and a few days ago, it was 1.0. Neither price has shown up in recent trades since April.

First solo block:

https://blockchain.info/tx/cba743ea1b7904c5624e0ee75f12d177ceb214c07f8e8b55ff2eb082404eb54a?show_adv=true

From now on the solo result of ASICMINER will have "Mined By ASICMiner" within the CoinBase.

You're not including transactions?

What?

https://blockchain.info/block-index/383941

Transaction Fees   0.1392 BTC


My question now going forward (for everyone, not specifically Friedcat), for an company like this, is there any advantage to using the pools at all?

Solo mining provides

1) No operator fees
2) All transaction fees (which have been consistently rising since Bitcoin started)
3) Less risk from pool owner trust
4) Less risk from pool downtime and DDOS attacks

At a cost of
1) More variance (who cares when you have significant hash power)



If another fork event occurs, friedcat will have to be on top of it and potentially change the version of the protocol used for solo mining. See http://bitcoin.org/may15.html

Think you will be looking at a little more for a 2012 BFL order, they seem to be going like hot cakes.

Thanks for the feedback. There has been zero interest in the initial offer. The offer has been updated above with higher rates and September 2012 pre-orders now have a price as well. Let's see if anyone is interested now.

April 19, 2013: Made a deal with uhoh: https://bitcointalk.org/index.php?topic=172288.0

Wanted:
1 Avalon ASIC batch 2

Offer:
200 BTC or best offer
Mutually-agreed escrow shall be used upon agreement and until the unit is received.
If you do not love BTC like I do and for some reason want USD, I am willing to consider allowing the escrow holder to exchange for USD while holding to limit exposure to USD/BTC rate while waiting.
Seller must provide proof of a legitimate order.

BTC is ready to send to escrow.

PM with offers.

I've tried to deal with sellers who are posting sales and in most cases, I did not have BTC ready in time. It's ready now.

We are awaiting the review and approval of our P&L from bitfunder. As soon as we have everything ready for our investors we will post the P&L and the 1st week dividend. I will post another update tomorrow @ 12:00 PM MST.

Thanks,

Why would bitfunder have to approve anything before you pay dividends?
