Something still running that has the COM port open? Maybe try a reboot.

That's odd.. "javaws -viewer" normally opens one window listing all cached Webstart apps and another window with the Java Control Panel.

Could you tell me which Linux distro and version this is? I'll see if I can reproduce the bug.

If you run from command line I guess you get the same stack trace as before.

The Trident animation library isn't initializing properly. I'm not sure why, but I thought it was worth a shot to clear the java cache and download the client anew.

Just to be sure the java cache is cleared, try running "javaws -viewer" from the command line. In the "java control panel" window click "settings" under temporary internet files. In the window that comes up, click "delete files" to clear everything out. Then restart the client. Does it work now?

The output from "java -version" might be handy too.

General advice, set your minimum difficulty to your hashrate in GH/s divided by 1.4. Some info on difficulty and work submits per minute:

Anything else?

Ah, I think we are finally on the track to finding out why the gauges don't work for some users.

Could you try clearing the java cache and restarting the client, to see if that works?

Thanks! Looking into this.


You can try some different settings and see what happens. Don't set the work intervals too high. You won't gain much by setting them higher than 20 ms.

Note that this will not be profitable anyway, due to the electricity costs. Use GPU mining as a learning tool to find out how mining works. Buy ASICs for actual mining.

I think Bitminter is best.

Yeah, sorry, I forgot to respond to that. It's a great idea. Not easily implemented the way stats are handled right now, but should be easy to do with the way I want to handle them in the future. So it won't be there tomorrow, but I definitely want to add that feature. Thanks for the idea.

It still says 1.5% fee near the top. The fee is 1%, donations are whatever you choose depending on which perks you want.

I don't understand the parts about Bitminter only being for beginners, or that the support isn't good. We have some miners who have been here since the summer of 2011 when Bitminter opened, and I spend a lot of time helping users whether they are old or new. We also have users helping other users in the chat and in this forum. Oh well.. everyone is entitled to their opinion.

I haven't seen that happen in the middle of mining before, only when starting. Have you tried a reboot? Or reinstalling the AMD drivers?

Pro Minter only makes the other perks free - it doesn't activate them.

You forgot the password bit. Put any password at all, anything would be accepted.

user:pass - (my user name)_(my worker name):x,(my user name)_(my worker name):x

For instance put x as password like I did above.


This is a bug I am trying to track down. The hashrate shows zero, but you can see you are mining because you are getting accepted proofs of work (yellow boxes). So the mining is working, but the hashrate gauges are not working.


Sounds like the firewall is being difficult. Can you connect through a proxy? Bitminter client doesn't support proxies though, so you'd have to either use one of those programs that can force a program to go through a proxy, or you could try bfgminer which has proxy support.

What most calculators don't take into account is subtracting pool fee, subtracting donations (if any), adding transaction fee income (if pool pays it), adding merged mining income (if pool pays it). Sometimes all this evens each other out though, and what you make is roughly the same as what the calculator says. Variance will of course make deviations from the expected average income.

At Bitminter you can choose whether to wait for confirmations or not. Default for new users is no waiting, but it requires a perk which again requires donating.

A shift is a set amount of work for the current difficulty. A round is the time and work between finding one block and finding the next one.

No. I've been told they work the same way blades do. So you connect them through a Stratum proxy (Slush's Stratum proxy, or bfgminer which can also work as a proxy).


Website had a short hickup. Sorry about that.

If mining is working, then there is no need to worry. The mining server will kick you out if things go wrong.

Communication errors with BFL units. Not sure why it happens. Someone told me once that replacing the USB cable fixed it for them. Reinstalling the drivers might be worth a shot too.

Yeah, seriously, take that advice. CPU mining hasn't made sense since 2011.

I think it's possible to CPU mine with bfgminer. Not sure if you need to compile your own or just use a command line switch..?

Using a horribly slow CPU miner to mine bitcoins is a very bad idea. I didn't have time to optimize Bitminter client for mining on CPU before CPU mining was already obsolete.

If you insist on CPU mining try a fast CPU miner mining litecoin. I don't know if it will cover the cost of electricity, but it will be a lot better than the first option.
