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.

Make Packages from all Installed Ports in FreeBSD

Sometimes it's useful to create .tbz packages of all the installed ports on your FreeBSD system. Whether it's for a backup or for use on other similar systems, using the ports that are already built to your liking can save lots of time.

procmail-wrapper FreeBSD 9.0 (i386) version for use with Virtualmin

This is similar to the Ubuntu PowerPC version found at but for FreeBSD 9.0 i386. If anyone wants a 64-bit version, ask and I will make one.

How to Use Disk Labels in NAS4Free or FreeNAS Legacy

You have a FreeNAS 7/NAS4Free server setup and you have several USB drives attached to it. Your ongoing issue is that every time you reboot your FreeNAS server the disk mounts get mixed up and the drive numbers are out of order. One day your 120GB Western Digital HDD is da0, then all of a sudden it becomes da2 while your Seagate 500GB HDD is now da0.

If you have more USB drives attached and you use software RAID. All of a sudden, your Western Digital HDD that stores all those vacation pictures becomes a member of a RAID set. Ouch!!

MySQL Fixing Host is blocked because of many connection errors

I've recently been experiencing a problem with some MySQL servers, "Host 'host_name' is blocked because of many connection errors.

Bypassing Virtual Machine Detection on VMWare Workstation

Often times you may run across some nasty software that will refuse to run inside a virtual environment.  Usually malware is the biggest culprit here, but some legitimate programs may also refuse to install if a virtual machine environment is detected.  Fortunately VMware has created a work around to prevent software from detecting a virtual machine.
