MemoryCoin / Debian Node Monitor Script (Keep your Listen [churn] Node running 24/7)

« on: January 16, 2014, 02:42:03 am »

This script was initially a solo miner, but I have converted it into an unbreakable node.

The auto restarter detects for an unresponsive daemon mainly by checking the size of the debug log.
It is also designed to backup the wallet twice in UNIXTIME-backup.wallet.dat in the root folder.

If the server is detected unresponsive on several occasions (4 crashes within the 20 second checks), the script will automatically clear the block database. If any more (10 crashes in 20 second checks), the entire .memorycoin and memorycoin/ folder will be deleted (wallet.dat is always preserved) and then completely rebuilt from source.

You may play around with the variables in the beginning of the file on line 2 and on line 454 of the script. I suggest you just keep them at default values.

There may be an issue if you lost the session and then the script would then enter an infinite loop. It would also take 100% CPU. I set a trap to prevent the user from accidentally closing the script. All you have to do is close the script with 'kill -9 mmc-churn-node.sh'; The other option is to use a screen and then detach/attach it.

This script runs on my churn node at 69.197.161.42:1968, also listed on http://www.mmc-chain.com/?engine=nodeexplorer

MemoryCoin / Memorycoin Lottery Idea [In Development]

« on: January 10, 2014, 06:38:48 am »

Please let me know your thoughts or suggestions for the lottery before I create the lotto system.
Here I can demonstrate my Lottery System (In words)

Ticket fees increase as more tickets are placed: ex. 12MMC for the first ticket, 14 MMC for the second, etc.. it discourages multiple entries and spirals the jackpot prize. ... 6 tickets = 100-ish MMC
Payout of 97.1968%
Megaspinner takes about 2 minutes for the first segment, a 30 minute pause, and then the final round will determine the winner #.. It requires a ton of randomization code. the spin can also be watched live on your web browser (ajax?)
Tickets are shuffled 36 times, and a random number is picked (1-36) 100 times -- The most picked random number will be used as the ticket index. numbers are then picked from the index 100 times and sorted from most to least picked.
A random integer from 1 to 1,000,000 is then chosen -- >500,000 = the most picked will be the winner list, <500,000 will choose the most unpicked list.
If multiple entries are chosen the same amount of times, they will have a round-off to be placed in the list from first to last. this may be good or bad, depending on if the list is least picked or most picked
The winner's list will then be respun 30 minutes later using a different algorithm.
Between the amount of winners: a list of their numbers are generated 50 times randomly.

A list of numbers are then generated from 1 to 50 until all the numbers equal the same number. This will be the special list used when sorting out the winners.

**An array of numbers between 0 and 1 will be generated 50 times until they either all equal 0 or 1. [0- most picked, 1- least picked.]

The numbers from the lists are then tallied up and sorted out from most picked or least picked.

The payouts will be paid out from first to last.

Payout Division - Jackpot System (2.8032% is kept by the house)

< 175 MMC - 1 Winner
> 175 MMC - Two Winners - Payout split - 72%, 28%
> 500 MMC - Three Winners - Payout split - 67%, 21%, 12%
> 1250 MMC - Four Winners - Payout Split - 63%, 19%, 13%, 5%
>2500 MMC - Five Winners - 54%, 21%, 14%, 7%, 4%
>5000 MMC - Six Winners - 47%, 21%, 13%, 10%, 6%, 3%
>10,000MMC - Seven Winners - 43% 19%, 15%, 10%, 7%, 4%, 2%

MemoryCoin / Memorycoin wallet CPU miner crashes on PC's with non-square cores

« on: January 09, 2014, 01:42:32 am »

I tried the pool miner on a laptop with three CPU's.
It just crashed.
This happens when I click Mine xx pool (should be easy) but it opens a cmd window and closes instantly.

Four cores do the trick but require some code to be changed in the wallet.
Try rounding the # of CPU cores to the nearest square number.

MemoryCoin / Post your MMC Miner Rig(s)

« on: January 05, 2014, 06:31:41 am »

I'll start.

All 9 are ready to hold Dual R9 280x's.

FX-8320 [$ Efficient vs. FX-8350]
Watercooled, hashing away at 3.5H/m @ 4.5GHz each & 20C Max.

I have two 8-port gigabit switches hooked up to a N-wireless adapter.

They tripped my circuit breaker a couple of times and I'm gonna have an electrician run two 80A wires down once I add more GPU's + upgrade the PSU's. Right now they're running on x2 15A trips

MemoryCoin / End of Year Profit Taking

Take profits now and buy more hardware by the new year ^.^
There's enough liquidity on the market for non-cloud miners.

MemoryCoin / Debian Linux Cloud/Server Miner Script

« on: December 23, 2013, 03:06:35 am »

Debian Linux Server/Cloud Miner Script

This is a Daemon Helper script that makes managing your MMC miner on Debian Linux seamless.

Use and test at your own risk.

I have been relentlessly working on this for a couple of days now + running it on my servers.

I've seen performance increases of 10-40% on most of my servers just by running this script.
Also, repairs and reinstallations are effortless.

It downloads and compiles the MMC Daemon from source using git.

Features:

Completely easy Installation
Easily Restart your Daemon
Easily clear Block DB
Rebuild from scratch for new versions or to start fresh
Get Daemon Information
Print Last debug lines
Watch Debug Information
Watch Daemon Statistics (fine tuned without daemon performance degradation)
Auto Restart Capability on crash (WIP)

Type this in console as root:
