641  Alternate cryptocurrencies / Altcoin Discussion / Re: artforz and coblee gpu mining litecoin since the start? on: February 10, 2012, 05:11:43 PM
CoinHunter, if you were just doing a public service to announce this, shouldn't the title for this post be "GPU mining on litecoin possible!" instead of accusing me of something that you have absolutely no proof of because I'm not doing it. If an efficient GPU miner for scrypt is possible, this is the first time I'm hearing it. I'm no expert in scrypt, but a few knowledgeable people I know have looked at it and determined that it is designed to not work well on GPUs. Is it possibl that they are wrong? sure, but until I see solid proof, this is just another FUD post from CoinHunter.

When using the icarus worker, if I stop the miner and restart it, the icarus worker will fail to start with this message:

Code:
Icarus board on /dev/tty.usbserial: Timeout waiting for validation job to finish

It seems like I have to disconnect and reconnect them in order for it to work again. Any ideas?

Here's the relevant part:

Code:
  # Single X6500 worker
  { \
    "type": worker.fpgamining.x6500.X6500Worker, \
    "deviceid": "AH00WOWD", \
    "firmware": "worker/fpgamining/firmware/ztexmerge_200mhz.bit", \
    "takeover": True, \
#    "uploadfirmware": True, \
  }, \

  # Single X6500 worker

Very sure. I programmed them using the x6500 software. I have all 5 up and running using 5 instances of your software with single x6500....but the hotplug won't work for whatever reason. Any suggestions?
No idea how hotplug cannot work if single workers do, that's really weird. They both enumerate all devices on the bus, just that the single worker skips everything where the serial doesn't match, and that hotplug spawns a single worker for every serial that it finds on the bus.
But you should be able to just copy the worker definition in the config file for all 5 boards instead of running 5 MPBM instances. That's basically what hotplug would do anyway.

I have 2 x6500 workers in a single instance of MPBM on my Mac.

I never got the hotplug working on my Mac either. I got the same error message. So I gave up and just specified the serial and that's been working fine.

Yes, it's really good.

@Coblee:
What kind of cooling setup do you have and what getwork interval did you have with the old miner? I epoxied my heatsinks, have an active 120mm fan over my X6500 and ran it with a getwork (-i) of 14 getting. I'm finding I get a steady 390-410mh/s (but usually 400). I 'm going to try out MPBM on the weekend when I get a chance.

Good decision. With the normal x6500 miner, I was only able to do 355 mhash/s with the 200mhz bitstream. With MPBM, it's showing me 393 mhash/s for the past day. This is running on a Mac and measured using Eclipse's share count. I'm not sure why it's so much better, but I'm not complaining!

I have epoxied my heatsinks also and have an active 120mm fan over 2 stacked x6500. I have getwork of 15. At first I thought the epoxy wasn't put on correctly so heat wasn't dissipating properly. But seeing that I'm getting much better results with MPBM makes me think the default x6500 miner wasn't efficient. It might also just be not efficient on a Mac.

I think we can all agree that MPBM is awesome! I think MPBM will become our recommended miner, and we will support and develop it into the future. We'll most likely be phasing out development on x6500-miner over time.

What are you going to do with the up to 1 trillion $ that you get from selling your RLCs? Will you always keep all that money in reserves or are you going to do fractional banking just like traditional banks? If you will keep that money in reserves, you risk having it stolen, embezzled, or just having need to use it because your company is running out of money. If you don't plan to keep all of it in reserves, then you are no better than the current banking system + paypal.

In a sense, you are just printing your own currency backed by USD. Just like the US printed dollar backed by gold. And maybe one day, you will remove that backing. I hope you are prepared for the legal mess you are getting into.

mine LTC on web pages (javascript miner), games, etc where CPU coin is stronger. Then the website/game developer can pay rewards in terms of LTC. Bitcoin wont be able to compete here. Other alt-coins (including custom altcoins by game owners) may indeed enter here, but its unlikely if they can use our LTC miners/ libraries for free.

Vanderbleek (https://bitcointalk.org/index.php?action=profile;u=44378) was working on a game that uses litecoin as a currency and generates litecoin in the background. I don't know the current status of it. You may want to contact him.

If we could have an online wallet for LTC just like blockchain's wallet, people wouldnt even need to download anything. They could just play games, spend their LTC on merchandise (or whatever).

There's already a litecoin instawallet created by g2x3k: http://wallet.it.cx/

Anyone working on an Icarus worker?

I might do that if someone can offer me access to a board for testing.

I might be able to do that. What kind of access do you need?
652  Bitcoin / Mining software (miners) / Re: Modular Python Bitcoin Miner - Official Thread on: February 08, 2012, 05:06:07 PM
Anyone have this working on a Mac? Before I try setting it up for my x6500 miners, wanted to make sure someone had already tested.

Yes, it's working on my Mac. I needed to install these 2:
http://sourceforge.net/projects/pyusb/files/PyUSB%201.0/1.0.0-alpha-2/pyusb-1.0.0a2.zip/download
http://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.8/

I finally got this working by installing libusb (and it does break the x6500 default miner)
This miner is fantastic! It has all the stats that I can think of in a nice layout... color coded as well!

Anyone working on an Icarus worker?

Well, I put the serial in the config.py myself:

Code:
  # Single X6500 worker
  { \
    # Worker module
    "type": worker.fpgamining.x6500.X6500Worker, \
    # Worker module parameters, in this case board serial number (default: take first available)
    "deviceid": "AH00WOWD", \
  }, \

  # Single X6500 worker
  { \
    # Worker module
    "type": worker.fpgamining.x6500.X6500Worker, \
    # Worker module parameters, in this case board serial number (default: take first available)
    "deviceid": "AH00WI18", \
  }, \

I'll take a case Cheesy

Aww, it won't scan the QR code Tongue

Too bad it takes 23 seconds per side of each mint to engrave and isn't practical as a product.

I was pleasantly surprised that the laser beam turns the clear plastic a deep copper color - which is highly unusual.  I was expecting a light melt or a white frost.

These mints are Trader Joe's Green Tea mints.  And I can't scan the QR code off the real mints either, it just doesn't work that well I guess.

I thought that was a photoshop. You actually made these. lol Smiley

Edible bitcoins... imagine if you really put a private key in those mints with 0.1 btc. That means by eating one, you are removing 0.1 btc from circulation for ever.
658  Bitcoin / Development & Technical Discussion / Re: Vanitygen: Vanity bitcoin address generator [v0.17] on: February 03, 2012, 07:13:22 PM
Anyone tell me how to generate LTC vanity addresses?

-X 48 does not seem to work.



$ ./vanitygen -X 48 L1QaZ
Prefix 'L1QaZ' not possible
Hint: valid bitcoin addresses begin with "1"

It works, it's just that the address versioning doesn't allow certain characters.

That's right. Litecoin addresses go from "LK..." to "Li..."
So 1 is not valid for the second character.

New windows client release: https://github.com/downloads/coblee/litecoin/litecoin-windows-client-0.5.0.9.zip

This just includes a small fix that addresses spam transactions for those of you still having problems with a bloated wallet.  Specifically, it includes this commit: https://github.com/coblee/litecoin/commit/c61d9e9717217c521c8746630c732347711cc7b5
Basically, when scanning blocks and transactions, it will ignore the transaction if the output is less than MinInput (defaults to 0.0001 ltc, but can be changed). So if you do a rescan, all the spam transactions will no longer be in your wallet.
