Yet another SHA256 crypto-currency based on Bitcoin. According to the developers Unobtanium is SHA256, Proof of Work only type coin with a block reward of 1 coin per block, halving every 102,000 blocks and finishing with a minimum subsidy of .00001 after 612,000 blocks. A maximum of 250,000 coins will be created.

To build Unobtanium on Ubuntu is very simple as long as you are using the correct version of the operating system.

Yet another SHA256 crypto-currency based on Bitcoin. According to the developers Bytecoin is a 99.9999% clone of Bitcoin with the only difference being the Genesis Block. Bytecoin is perhaps considered to be a rare "second chance" on getting in on the opportunity.

Zetacoin is another SHA-256 crypto-currency based on Bitcoin. It's only been around since August 2013 and it's mining difficulty (as of Nov 2013) is not yet as insanely high as Bitcoin. Zetacoins have some value in the market, but I think I'll hold on to mine for the time being. I wanted to get a Zetacoin node running alongside my Bitcoin and Litecoin nodes. After a few failures I determine it's currently not possible (at least with what I know) to build Zetacoin on FreeBSD.

The Bitcoin and Litecoin ports don't include any rc.d start up and shutdown scripts for FreeBSD. So I went ahead and made some. In order to use these scripts you must do some additional work after installing the respective ports.

Roundcube has a nice little plugin named "password" that allows your users to change their passwords using the Roundcube Webmail interface. However, the current "drivers" do not work very well in a secure environment. Most drivers need you to have the "sudo" command installed and enabled for the Apache HTTP user. Others require that they be run as root.
