1  Alternate cryptocurrencies / Altcoin Discussion / Chunkhost Bitcoin Black Friday promotion - double credit for Bitcoin deposits! on: November 29, 2013, 03:42:41 PM
Just a heads-up to all VPS-mining folks: ChunkHost is offering 2x deposits for today only if you deposit using Bitcoin! Plans are a flat $9 a month with an optional upgrade fee. The most basic plan offers 1GB RAM, 30GB SSD storage, 2 CPU cores, and 2TB Transfer/month. If you are considering a DigitalOcean VPS but don't have a Paypal account, you can use this instead!

Sign up here!

Note: if you wish to mine Protoshares, beware of the 1GB memory limitation. I would suggest limiting your nonce range to reduce memory usage.
Also, when compiling your clients it might be best to make a swap file, just in case: instructions

Instructions
1. Fund your account. It is recommmended to fund it with more so that you can run more miners concurrently. 0.05 BTC should be fine, and gives you over $110 of credit.
2. Set up the chunk. Use Ubuntu 12.04 or 13.10 for the OS.  The root password will be emailed to you.
3. SSH into the chunk using either putty (Windows) or ssh (linux). Run the following:
Code:
# apt-get update ; apt-get upgrade.
# sudo apt-get install make automake git build-essential libcurl4-openssl-dev
This will provide the necessary tools for CPU miner building.
4. Compile CPU miners as usual. Warning: flag "-O3" or flat "-march=native" seems to cause SIGILL to be thrown.

Benchmark results:
Quark = 150 KH/s using https://github.com/uncle-bob/quarkcoin-cpuminer
Yacoin = 25 Hash/s using mikealh yacoin cpuminer at http://yacointalk.com/index.php?topic=264.0
scrypt = 9.5 KH/s using pooler cpuminer
SHA-256 = 5.2 MH/s using pooler cpuminer

Is there any way to sandbox clients? Would it be possible to put it in a VM?
3  Alternate cryptocurrencies / Altcoin Discussion / Blakecoin Google-Docs exchange on: October 31, 2013, 05:41:35 AM
I have started a BLC/BTC Google Docs exchange, found here. Fees are 0.5%, higher than Cryptsy et al. since this is a manual job.
This exchange will open now and close 8 hours from now, unless I can find someone in the Blakecoin community to take over while I am not around.

How to use:

1. Send me a message stating that you wish to deposit. I will generate a BLC and BTC address for you and send it to you.

2. After you have deposited and I have replied with the acknowledgement, you can send me commands:
  • Place orders like: "Buy 100 BLC for 0.005 BTC/BLC" or "Sell 50 BLC for 9.301 BTC/BLC". I will send you the order ID. You can check on the order via the orderbook, which lists order IDs. To cancel it, just message me so.
  • If you just want to buy/sell at all costs, message me in one of the following formats: "Buy/Sell BLC for 2.0 BTC at all costs" or "Buy/Sell 500 BLC at all costs". I will tell you the amount spent and the amount received. Warning: You may run into the orders selling 1 BLC for 100 million BTC or those buying 100 million BLC for 1 BTC!
  • To do a withdraw, send me a message just saying "I wish to withdraw <amount,currency> to <address>". I will send it back to your address with fees of 0.0015 BTC or 0.25 BLC.

3. If the exchange closes, I will send you back your funds totally, and message you the txid.
4  Alternate cryptocurrencies / Altcoin Discussion / BSOD when closing client on: October 13, 2013, 01:02:26 AM
In the past few days, I have experienced BSODs multiple times related to ndis.sys when closing clients. After searching, I believe that this issue is related to my network card (Qualcomm Atheros AR9565 802.11b/g/n Wi-Fi Adapter). I have tried two driver versions (10.0.0.212 and 222), and both have experienced BSODs.

The three clients which I have had BSODs on are Offerings From Ctlhulu, SIF and Kingcoin. This issue occurs intermittently and is preceded by me entering "stop" into the debug console and the window freezing.

Does anyone have information regarding this issue?

I am running Windows 8 on a HP laptop. On the computer I have Avast and an expired copy of Norton (which I couldn't be bothered to uninstall).
Every time it crashes, quite a few processes are running. Chrome, Notepad are the two that I remember I always had open when I typed "stop" and the BSOD happened.
5  Alternate cryptocurrencies / Altcoin Discussion / Pools issue on: October 11, 2013, 02:36:13 PM
This has happened to me many times already.

So I log in to a pool wanting to start mining, go to the workers page... poof! I'm logged out. Try it again... the same results yet again. I noticed that this only happens on mmcfe-based pools (and not all of them).

Is that an issue with the pool or with some settings in my browser? I'm using Chrome 30.0.1599.69 m, with the extensions ABP, RES, Ghostery (and some others, but those were installed after the logout issue began happening)
6  Alternate cryptocurrencies / Altcoin Discussion / Merged-mining on: October 07, 2013, 11:28:13 PM
How would one set-up merged mining if he/she is a pool operator (not p2pool)?

Say Mr. Friedcat decides he also wants to merged-mine NMC, DVC and (oh, I dunno) I0C.
7  Alternate cryptocurrencies / Altcoin Discussion / Setting up a mining pool on: September 29, 2013, 06:39:39 AM
I am interested in setting up a mining pool for several coins, and am looking into different hosting packages.

Usually, do mining pools use Website Hosting or VPS hosting?

If I want to buy mining equipment in Singapore, what is my best option? I understand that ASICMINER is currently being sold through resellers, but I don't see any sellers serving SG...

Quote
    US: eleuthria, CanaryInTheMine, SilentSonicBoom
    Canada: teek
    EU, Switzerland and North Europe: yxt
    China, Taiwan, Hong Kong and Macau: rockxie
    Australia: asicminer@swishbits.com.au
    India: Pinwheel

    Singapore: HuhHuh

(Yes, I know that electricity costs in SG are prohibitive, but I'm not exactly looking to make ROI, as you can see)
9  Alternate cryptocurrencies / Altcoin Discussion / TRC getting attacked (as usual) on: August 08, 2013, 03:56:59 PM
Difficulty has been stuck at 5255.042 for many blocks now...

Look:


The timestamps are also jumping back and forth...

The fuzziness is due to the block times jumping forward 2min, back 3min, forward 2.3min, ...

Both the block explorer and CoinChoose say there is currently 2.5TH/s hitting TRC, up from 500+ GH/s earlier today...

(Question here: Seeing as the block timings are spaced very closely, how is the difficulty not skyrocketing?)

10  Other / Beginners & Help / Issues with primecoind on: July 10, 2013, 11:18:09 PM
Today, I successfully built primecoind.exe on Windows, applying some of the optimisations mentioned in the main thread.

However, when I try to run primecoind.exe -gen, it exits with the following error:
"Error: Error initializing wallet database environment C:\Users\[name]\AppData\Roaming\Primecoin!"

I tried searching for methods to fix this problem. With the bitcoin client, this could be fixed by running "primecoind-old.exe -detachdb" (mentioned in issue #2083), but with this it still does not work.

Has anyone else encountered this problem, and how would I fix it?

(note: the issue in question is https://github.com/bitcoin/bitcoin/issues/2083)
