If you setup namecoin merged mining and paid out on both, I might switch my miner. That would reduce variance on the altchain giving your pool an advantage over p2pool.

About Tor mining - it works even behind strict firewalls, open port 443 is enough.
So if I were to use diablominer would I still need to put port 8332, or could I use 443?
Port 8332 is blocked (and nearly everything else).
Do I need to have the bitcoin client installed on every computer that I mine on?  I remember once having to create a bitcoin.conf file.  It wouldn't even be able to update because of the blocked 8332.
BTW I never solo mine, so that is not an issue.
He means 443 outbound. It's a pretty rare thing to block. You still connect to port 8332

I would love to see a dedicated, open protocol and interface other than USB that could be used for daisy-chaining many devices. If the protocol and interface were cheap and open, it could be possible to apply the same interface across diverse products, and all control them on the same bus.

There are a number of bus technologies that already exist, but they all need to be properly evaluated, and a cost assigned to them, i.e. cost per node in wholesale manufacturing quantities. Often in these discussions Ethernet comes up and is discussed, but is determined to have a cost per node that is too great to be of value.

To accompany this lofty initiative, an inexpensive and useable head controller/marshaling device needs to also be designed. It could be based on something extremely simple such as Atmega/PIC/Basic Stamp/Arduino, or something a bit more powerful based on ARM and/or x86. It would be self-contained - possibly a USB, JTAG, or serial port for programming, and an Ethernet port for communication during normal tasks.

This way, a single device (or more, if N+ redundancy were built in) could control a wide number of devices from many manufacturers, assuming they could be convinced to include the special interface - thus the need for it to be inexpensive.
We don't really need even more standards do we? What's wrong with USB?

Just ran cgminer on my router with CPU mining enabled for the hell of it (because I can).
Over the 20 mins I ran it, it averaged a whopping 0.1MH/s, and didn't submit a single share... it was taking so long, the long-poll came around and reset the work.

Incidently, memory usage was ~1900bytes or maybe Kbytes (I'm not sure what HTOP lists mem in), either way, nice small footprint.
Also, the shares counters for the CPU made there way across the screen every update, must be some problem with ncurses there.
I am pretty sure you are killing your router with that.  The CPUs usually have pretty poor cooling.

Indeed. Most of them get very hot.

I would discourage trying to mine on any router simply because the heat mining produces was not meant to be dissipated into that tiny router case.

Maybe try adding a heatsink and fan and air paths if you want to do that. investing your time in something useful.

One thing that'd help is a bitcoin wallet for an ipod or android device.

I'm not sure I understand the purpose of this sentence. Are you suggesting this doesn't exist yet? Or are you just saying it would help, which of course, something like Spinner makes things almost too easy.  Wink

I didn't know a wallet on an ios or android device existed, if it does.

WAY more than it's worth Cheesy

I'll be compiling cgminer for myself when new versions come out, so I can release that (it'll work on both the above routers).
I could probably write some sort of guide on how to set it up.
I don't think cgminer has api support for FPGAs (yet), so I don't think Anubis will work.

Correct.  The original author said he would share the source if someone wanted to continue the project, but he hasn't followed up on that.

I think the title change is going to draw more attention to the similar names than what you would have seen before.

I'm not worried about people noticing the similarity in names.  I already expect people will notice both.  I just want to make sure no one mistakenly assumes real association between the two "projects." 

At least that one is called "The Armory" and I am just "Armory." 
TBH, I think Armory is kind of a strange name for this client.  I associate an armory with weapons storage, so coin storage doesn't really follow.

So I can attach my BFLs to it! Why else!?
Ah yes. Forgot what this thread was about lol

Most people are running it on x86 and that is where the support is at. ARM is just a hack and rarely done except by the complicated few who can't spend a few bucks to get a proper desktop for FPGA only mining.
It is a mining rig and so should be considered a server, not a desktop.

The whole point of FPGAs is the lower wattage. ARM beats the crap out of x86 when it comes to power usage.

If you can get the system working we have some interesting numbers.

16 x 5970 @ 390 MH/s per GPU = 12480 MH/s
At the current difficulty and at a value of $4.8 per BTC would see break even in less than 6 months.
This includes $1200 for the system build and $400 per 5970.

16 X 7990 @ 600 MH/s per GPU = 19200 MH/s
At the current difficulty and at a value of $4.8 per BTC would see break even in 7 months.
This includes $1200 for the system build and $849 per 7990

It would be nice if it can be hashing before the halving.

Except you cant buy 5970s, and 7990s will be dropping in about 6 months.... so buy the 5970s now, sell them, and replace them with 7990s Wink

Did you mean you CAN buy 5970's? 

Nope, can't. Almost all the used ones on ebay are owned by insane overclocker gamer types, and have done dumb shit like throw out the stock hsf in favor of improperly installing a wc block that probably cracked the dies.

Total YMMV territory.


Huh.  I have purchased at least 8 off of Ebay, and every single one of them is working great.  The only issue I had was a bad fan, and that fixed with a $39 fan and about 20 minutes work. 

Have you had bad experiences personally, or are you simply speculating? 

Aggregating bad experiences of others.
You can add 3 good experiences to your list then.  I ordered all 3 of my cards off ebay and have had great luck.

Just try to use your ARM linux as a workstation with java, eclipse, chrome WITH flash support and spotify, skype, wine etc. If you wan't to do anything else in your life you won't be able to.

Exactly. All these fools thinking they will go for ARM or MIPS or another BS architecture like that will hit a brick wall.

Fact of the matter is that x86 is KING and most supported. No x86, no dice.

Stick to i686 or amd64 if you don't want to be dreaming about cross compiling in your sleep Tongue
I don't think anyone plans on using the beagleboard as a workstation.  If this is a dedicated FPGA mining setup, it won't need to have any of that bloat on it.  I don't see a problem.

How does the main wallet know when a watching wallet generates new addresses?

Say 1000 customer's come to the site and each get a new address.  Do I have to run something on the main wallet that makes it generate (the same) 1000 addresses, or is this done automatically somehow?

The main wallet is always looking ahead 100 addresses.  As soon as a transaction appears in the blockchain that contains an address not officially generated yet, the wallet will then extend the pool and continue watching.  As long there are no stretches of consecutive unused keys greater than 100 in length, the other wallet will automatically follow along.  100 is just the default, and can be manually increased by using "wlt.setAddrPoolSize(10000)", if your use case results in [potentially] much longer strings of usued keys.  Finally, if you know something like this happened, you can manually tell the wallet to extend the keypool (just not through the GUI, yet).
Cool. I figured it was something like this.

Now I just need the spare RAM Smiley

We don't know how it works. I'm a gun enthusiast and there could be a valid and legal market place for this. Why would this market be any different from any other? I've bought a gun online before, legally.

Pretty much there are 3 steps.
1). find and pay for the gun via paypal, credit card, OR BITCOIN
2). That FFL ships it to an FFL dealer near you
3). you go to your FFL and do the required paperwork. If you fail, you don't get the gun.

OR, if you have your C&R (curio and relic) FFL (federal firearms license) then you can get a C&R firearm sent to your house directly.

Or, in other countries it may vary.


Until we get more information on how it works, it's not fair to the market to automatically assume it's illegal.
While we shouldn't jump to conclusions about legality, I have a feeling that people going through Tor aren't going to be filling out all the proper paperwork with a FFL dealer...
