How can I participate in a mining pool that is mining Litecoins?

To date I’ve only participated in mining GPU-optimised crypto currencies. I wondered what happens when I pointed my GPU miner to a Litecoin mining pool worker, Litecoin being designed to be optimised for CPU mining.

I tried do this for just three shares on and according to guiminer (running Phoenix) two of them were rejected as stale and one was accepted. However, my worker on registered no shares submitted at all (which is probably correct, since it’s likely a GPU miner won’t work at all for Litecoin).

If I can’t use Phoenix, then what do I use to participate in a Litecoin mining pool?

What Bitcoin Mixing/Laundry Services are availble today?

A Bitcoin Laundry or Mixing Service is a service that accepts BTC payments, and returns the same BTC amount, only from coins that are unassociated to the original BTC. It is a privacy service that works well if it has massive usage.

What are some good mixing services? Is there any data on how well they actually anonymize (e.g. what size are their “stashes” or user base (bigger stash = bigger anonymity)?

When building bitcoind, I receive error “headers.h:36:20: fatal error: db_cxx.h: No such file or directory”

When building bitcoind on LinuxCoin (Debian based), I receive this error

“headers.h:36:20: fatal error: db_cxx.h: No such file or directory”

following the instructions at

I believe the error is caused by the package “libdb4.8++-dev” being non-existant for the distro, as when attempting to “apt-get install” that, I get:

Package libdb4.8++-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘libdb4.8++-dev’ has no installation candidate

NOTE: libdb4.8-dev and all other dependencies are already installed.

It’s probably a silly mistake on my part but any help is appreciated! Thanks.

Is there an easy way to check out the market cap of the alternative currencies?

Ideally, I’d like to see a pie chart with the whole pie being “Bitcoin-derived crypto currencies”, and each major alternative represented as a market cap in Bitcoins and USD.

Currently, from what I gather we have:

  • Bitcoin – 7,415,750 BTC = $34,854,025 = 99.7%
  • Namecoin – 959,150 NMC = 25,897 BTC = $121,716 = 0.3%

I don’t know where to get data on other crypto currencies right now, and if they even have any significant market cap.
