I just started using blockchain.info as opposed to bitcoin-qt, and noticed right away that blockchain says my wallet has fewer bitcoins than the windows client. I started looking at the accounting of both, and noticed immediately that blockchain has incorrectly added figures starting from some of my oldest transactions. Namely here is the accounting that blockchain.info shows:



Not sure how it figures .67 minus .55 leaves a balance of zero.

Am I missing something here?

I'm in need of installing older radeon drivers (12.x) on my mining rig, but the installer fails on DKMS with my 3.7.0-7-generic kernel, so I can't install them.

Any linux aficionados know how to work around this problem, other than by downgrading the kernel?

Right now I have three mining rigs, and for a while all three were working fine. However I had to reboot my server that is also functioning as a mining rig, and little was I aware that since I had last rebooted it, Ubuntu (which was set to security only updates) since went through multiple kernel revisions and dkms driver revisions (and strangely enough, these "security" updates to these kernels often seem to break support for my ZFS modules.) When it came back up, that mining node (running cgminer) never came up with it.

cgminer was indicating for every single share that there is a hardware and the nonce was invalid. I know for a fact that this isn't a hardware problem, because I installed steam and ran a game to make sure that everything was working as it should. No glitches or anything, game renders perfectly. I went through the song and dance of repeatedly clearing and reinstalling drivers, trying different ones, etc, and the result was always the same. I also tried using bfgminer instead - same problem. I tried using catalyst 11.11 as is often suggested elsewhere, and that particular driver won't even install (I think maybe it is incompatible with kernel 3.7?)

I've tried updating the APP SDK to 2.8 by the way, problem still exists.

Now, I've been looking all over the place for methods of resolving the hardware nonce issue, and both here and elsewhere most of these issues are old, and I can't tell if there is some kind of game changer about the 3.7 kernel, or the newer catalyst drivers. On one of my mining rigs, I did have problems with cgminer crashing when used with a newer catalyst driver, I had to downgrade to I think an 11 series driver before it would run at all. Apparently the cause of this is due to 5xxx and 6xxx cards not working correctly with cgminer if using the newer drivers, and going to an old one fixes it.

If this also applies to linux, then how would I get this to work? It will be a major pain in the butt to roll back every single driver and other whatnot that upgraded along with that kernel just to use an older version of the catalyst driver, so I'm hoping to avoid that if I can. Anybody have any other ideas? Again, with everything in its current state, games actually run correctly. So other than for bitcoin mining, the graphics driver is behaving exactly as its supposed to. And again, this problem happens in both cgminer and bfgminer with APP SDK 2.8 installed. (By the way, is there any way to determine whether these miners are actually using that one or are using their own compiled in one?)

I started mining bitcoins for the first time back in January, and based on my research I had made the determination that eligius would be my best choice. Right now my mining works like this: A radeon 5750 and a 7850, both overclocked, on two separate machines, with a combined hash rate of roughly 550Mh/s. I didn't buy these cards for mining, rather they are cards for gaming that I already had, so I figured I would experiment with mining, and so far I like the results. However lately I keep running into this:

Naturally, I'm not getting anywhere if my client can't actually participate in the mining process. I did research on p2pool and I heard something about variance being no good. My statistics page here doesn't seem to indicate that I am doing that well on eligius though:

Many of the dips are from suspending the mining while I play games, but I haven't played any games at all in the last two weeks. My network works fine (I am a network engineer btw) as I do regular SLA testing (hobby of mine) and there are no ISP connectivity issues indicated by that, nor do I notice any downtime from any other sites.

I realize that it is basically impossible to accurately predict how much you'll actually be able to mine. However, is there at least any statistic gathering anywhere that will give me an idea if I'll get better results from another pool?
