Thanks for spotting that! I rearranged some things last night and must have forgot to restart one of the workers. Sorry about that!

I just noticed that fpga6 is reporting 0 MHash/s, what happened?

How do I buy shares?

Make a sh-script that does this, then check the crontab (/etc/crontab?). Most system have directories (cron.daily, for example). Just put/link your script into that directory. You can also make an enty in crontab for the script, if you prefer. There's also a "crontab" utility to do this, but I never used that.

Thanks, everyone for letting me know about the problem last night. By the time I fixed it I needed to go to sleep, which is why I didn't reply to you guys last night. Sorry about that.

What happened was that cdhowie's bitcoin-mining-proxy started going crazy. This is where you see the first jump off the top of the graph. At that point, the proxy started submitting huge amounts of duplicate work. I saw it do that once before and a simple "apachectl restart" fixed it, so I did that and went back out to the living room to spend the night with my family. When I went to check on it, it wasn't fixed. Finally, I discovered that mysql was to blame, and it was because the database had overfilled the hard drive on the server. Actually, it's not a hard drive but a 4 GB USB drive...

Figuring out how to clear out the database when I can't even get mysql to start up because the database was too large was a bit of a challenge. I ended up deleting some stuff off the disk to make just enough room, then started mysql and cleared out the work_data and submitted_work tables. Finally, it was working again. I restarted all the FPGAs and pointed a couple extra at this group to make up for the lost time (that explains why you saw huge rates on FPGAs 0, 1, and 2, Arsen).

The system is back in action running along smoothly! Anyone know the best way to set up a cron job to trim the database nightly? Also, I'll upgrade to a larger USB drive soon.

By the way, the clocks are currently at 166.6 MHz on all FPGAs, but I will boost this up soon. The number of rejects are vastly reduced due to m0mchil's beautiful bug fix (incorporated in x6500-miner v0.2).

Thanks again!

Rejects also decreased. If this is result of new code then GREAT job ! Next dividends should be 30% higher!

Looks like an extreme overclocking (in comparison with original rate) %)

and the graph is out of 3000 range in the statistics picture

Seems to be back up... Thanks fizzisist!

Indeed... I've PM fizzisist in case he gets notifications for that and not this thread.

Rate of all cards is displayed as zero...

To be honest, I'm not exactly sure the reason for the high rejects. I'm guessing that long-polling still isn't working perfectly (for example, I can see that shares occasionally get submitted right after a long-poll event, because it's not a hard stop). The software is a work in progress...


I was wondering if anyone would notice. We're testing some new firmware with a higher hashrate! It should be released to the public soon.

Dividends have been paid for the week of 12/26!

Total paid to 6000 shares: 12.40767051 BTC
Dividend per share: 0.00206794 BTC

Our biggest dividend yet!

looks like the mhash number went up recently. Any story to that?

I've just look at statistic page on contract.fpgamining.com and I saw that there is 8% of rejected shares. Why its so high?

Dividends have been paid for the week of 12/19!

Another late dividend payment this week, but this time it was because GLBSE was down when I tried to go pay it. Fortunately, nefario was very helpful and quick to bring it back online. I'll get back on schedule this weekend, I promise!

Total paid to 6000 shares: 9.85384928 BTC
Dividend per share: 0.00164230 BTC

That brings the total earned to about 69 BTC!

P.S. Thanks for answering the questions about share price and projected earnings, Dexter770221! Everything you said was correct. The only thing I would add is that the weekly earnings will also fluctuate a bit due to luck.

Current price you can find here:
http://charts.glbse.com/markets/FPGA.contract.html
0.35BTC/share last price. If you placed order to buy for 0.25/share then you have to wait until someone decide to sell at that price. But it may take very long time becuse the lowest sell offer is 0.35/share.
If you buy 4 shares then your weekly income will be 4*0.00186695=0.0074678 BTC. And of course that depends on bitcoin difficulty (most) and mining power of FPGA's, and some other stuff like network failures or other disasters...

Is it still .25BTC/share? Im kinda confused how this works but on GBLSE I have a buy order on FPGA.contract for 4 shares @ total of 1BTC...this correct?
And, by spending 1btc I will get divdends weekly...and not have to spend more btc? right?

Dividends have been paid for the week of 12/12

Another week, another dividend payment. Sorry that this one came a little late. I was traveling and had only limited access to the internet.

Total paid to 6000 shares: 11.20173506 BTC
Dividend per share: 0.00186695 BTC

This brings the total paid to investors to 59 BTC in the 2 months since the IPO! Not too shabby!

Dividends have been paid for the week of 12/5!

This is our biggest dividend yet, and the first one with a full week of mining at full capacity (7 X6500s)!

Total paid to 6000 shares: 11.27463457 BTC
Dividend per share: 0.001879106 BTC

Good news for all those that bought shares in the last few days at this latest price!

You would have to buy 20 times as many shares as you have now, you're surely aware of that?

There's no free lunch.

+1.  Can you do all the work while we just watch?
