How to Build Bytecoin on Ubuntu Linux

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.

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

How to Build Zetacoin

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.

Roundcube Password Change Plugin Enhancement

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.

Resize Existing FreeBSD Root Partition or Slice Safely Without Re-Installing or Rebooting

There comes a time when your FreeBSD root partition (or slice) is just too small to be of any use. You've already moved /var, /usr, and /tmp to separate disks, you've tried cleaning up some logs, clearing cache, and even run pkg clean. There just isn't anything else you can delete. The problem is it was initially created too small when FreeBSD installed.
