Ok. Let's assume that some fearless dudes out there have plugged some Radeons into their colleagues' and secretaries' workstations. Let's also assume that those jail-defying dudes have forced their workmates to run some Linux flavour on those PCs (a long shot, but I know of at least one scumbag person who has).

Great. So far we have a mining rig running on free electricity, internet and OS, but those pesky colleagues keep bitching about how slow it is to switch tasks and their screens get messed up with artifacts and their Libreoffice Writer crashes and their shiny X session is insufferable and, and, and to no end.

The obvious solution is to set a cron job to stop cgminer at 08:00 and restart it at whenever the get-the-hell-outta-here hour is. But then, you've paid in preciousss gold for a GPU that's idling for hours between wordprocessors and spreadsheets and the very thought is killing you.

The next best solution is telling cron to just lower the intensity to 10-12 at 08:00 and reset it to 20 at get-the-hell-outta-here hour. Now, that's better.

But nooooooooooooo. Your hard-earned gold deserves even better. You demand a tool that detects when that sucker has stopped typing or touching the mouse, sets intensity to maximum and then waits until that sucker has hung up the phone and touched the mouse again. Then and only then it lowers intensity to levels undetectable.

Your demands have been met; this little tool squeezes the last MH/s out of your GPUs and turns it into profit. And keeps your workmates happy.


A little tweaking is required on your side, namely the fullint and halfint strings. For example, this dude I know has found that his workmates' tolerance threshold was good even at 15 intensity. YMMV. The tool checks for activity every second; it doesn't make any sense to set it lower. It also prints relative information every 10 seconds, so you can (should) run it in a screen(1) and check it remotely. It doesn't check whether the miner is running; it just tries to set its intensity and assumes RPC port 4028. Compilation instructions are in the top comment.

If anyone finds it useful and profitable, show your appreciation to 1Ls3Ug9V2J83XLsg9EFXgLX7ebSwXc39ix

Share and enjoy and profit!

[EDIT] I forgot to mention, you need netcat(1) to pass the commands to cgminer.

A couple of things pop in my mind:

1. The mobo underclocks the CPUs too agressively, look at the "Cool'n'Quiet" BIOS setting (it shouldn't though, given the load). Issuing 'lscpu' on a terminal will show you the current MHz.

2. The memory modules might be too slow. Replace them with a couple from a 'fast' rig to see if it makes any difference.

As a matter of fact, I've left the bot running since my last post. It started at 2 BTC and again slowly lowered to 1.7 overnight. Now it is at 1.919 but I can't see the graph as I'm running it on an old Pentium 3 and it times-out drawing it.

Anyway, it clearly needs tweaking, but presently I don't have much free time to devote.

I left the bot running for 20 hours, using the settings of woutie70. Here's the data of the last transaction and the accompanying chart. The initial $fake_btc_balance was set to 2.

*** Processing order...array ( 8 )
  ["type"]=> string(3) "ask"
  ["amount"]=> float(1.8646517758757)
  ["price"]=> string(9) "952.99500"
  ["datetime"]=> string(19) "2014-01-12 20:12:07"
  ["prem"]=> string(6) "profit"



The results are not very encouraging, but I'll do another overnight run with the default settings from github and see how it goes. intrd, please push the new chart code to the repo, as pChart isn't very legible after a few hours.

First of all, thanks for making this tool open source. I believe that with enough feedback from its users you'll deliver a solid final product. I'm using it right now on linux at paper mode, testing to see how it goes, using the settings woutie70 reported as "perfect".

The least I can do is provide a good start_hal10k.sh for UNIX-like systems:


I'll leave hal10k (what a cool name, BTW) running all night and report back with the results.

I apologize, you're right. It was the very first article in their scrolling news frame though and I must've missed it.

Anyway, it's not hatred, just plain scepticism. A £405 deposit for the 5 MH/s is not an amount I can really afford to spare in case this thing turns awry.

But, sir, Alpha Technology is located at 66 Dickenson Road! I'm confident you're reaching here

Has anyone actually contacted Dexcel Designs to confirm their alleged partnership?

That's what happens to aggressively premined cryptocoins.

Oh-so-cool design. Serious stuff.

Great news!

Thanks.

Appreciate it.

MWAHAHAHAHAHAHAHAHA! 

You sire just made my day!

I joined the CAT launch at the very beginning and made 300 cats CPU-mining (~ 120 KH/s) in 3 hours, before the diff exploded. Now, with 2 7870s @ 800 KH/s I got the cock.

I'd only mined 56 with 0.7 MH/s at ogc.idcray, what gives? Anyway, I'm outta this instamined crapcoin.

WTS 56 OGC, pm w/ offers.

Just saw the instamine code. Dropping out. The dev^Wcloner is a fucking liar.

Oh, wait, I must be politically correct. He's not a liar, he's truth-challenged.
