Install Zetacoin on FreeBSD

Zetacoin is a digital currency that is similar to Bitcoin but with faster conformation times and quicker difficulty adjustments. Installing Zetacoin on FreeBSD is very easy.

Problem with USB Devices on USB Hubs that Won't get Recognized after Rebooting Windows

A problem that you may run into with some poorly designed USB hubs is that the devices attached or plugged into the hub will no longer show up or get recognized in Windows after your system has been rebooted.    You try powering it off and on, then unplug it, re-plug, reboot, etc...
Windows may even hang during boot while the USB hub is plugged in.

How to Build Terracoin on Ubuntu Linux

Yet another SHA256 crypto-currency based on Bitcoin. Terracoins are issued to enduser nodes that verify transactions through computing power; it is established that there will be a limited and scheduled release of no more than 42 million coins.

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

How to Build OpenSource Coin on Ububtu Linux

Yet another SHA256 crypto-currency based on Bitcoin. According to the developers OpenSource Coin (OCoin) is is a SHA 256 POW/POS cryptocurrency with 1 minute block times, transaction messages and starting diff of 1, and a total of 21 million coins to be minted proof of work and unlimited proof of stake.

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

How to Build Unobtanium on Ubuntu Linux

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.

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.

FreeBSD rc.d Scripts for Bitcoin and Litecoin

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 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 Your Existing FreeBSD Root Partition/Slice Safely Without Re-Installing

There comes a time when your FreeBSD root partition is just too small to be of any use. You've already moved /var, /usr, and /tmp to separate disks and there just isn't anything else you can delete. The problem being that you initially created the partition to be too small when FreeBSD was first setup.
