Title: CoreMiner (cuda)
Post by: curaga on March 07, 2014, 06:03:26 AM

I have a Core 5.2 build running a miner here, so I clearly must show it off, to fend off the occasional question "can you" ;)

It boots from a ~60mb usb image, no drives, easily replicable if needed. Maxwell 750 Ti, getting 288 khash/s in scrypt coins.
I added a led matrix screen on top to provide at-a-glance status updates, without needing another computer to ssh in and check.

The screen is a B1248 model, connected via usb, available between 10-30$ a piece from China depending on quantity. It has good linux support with a multitude of implementations (ruby, perl, even C#). Sadly there was no light implementation, and I wasn't too eager to install Ruby on a minimal build, so a C port had to be done ;)

cudaminer.tcz and ledmsg.tcz have been posted to the repo. The nvidia driver used is not, because it's a cut-down version without X support.

Not data, altcoins (virtual currency).

Several countries have already decided that Bitcoin (and presumably other similar items) is not a currency, and the U.S. will probably follow suit. Bitcoin trading and mining may become taxable:

Well this is the offtopic section, so economics should be fine ;)

Finland has already decided to consider bitcoins as property. This doesn't really matter though, as you pay all the same taxes as if it were currency, with the exception of VAT. If I kept an account in USD, I'd still need to pay tax if the EUR-USD exchange rate changed and gave me paper profit at the end of my fiscal year.

VAT can be worked around by trading with non-EU entities - as VAT does not apply to transactions outside the EU as a rule (with some exceptions, that don't matter here).

So the net effect of the decision only affects which accounting account the profits go in.
