This is my first blog for a very very long time. I stopped blogging a couple of years ago when I started working on my book and after I finally finished the book I felt I needed a break to recuperate.
However, I have finally decided to put my toe back in the water. This isn’t a very serious post but I hope you find it thought provoking and a bit of fun.

DEFINElists the conditions a row may meet; it doesn't always work the way you expect, especially if you use aggregates in the condition.
I'm somewhat of a pacifist, but I appreciate the efforts of the brave in years past. I certainly felt an urge to to shake the hands of some of the aging veterans we saw as we passed the WWII memorial.
What moved me most, however, was walking through the Lincoln memorial.
There was some amazing prose on those walls. Considered words, unbiased by the various media of (more...)

Boy that was a long trip.
Sure, Perth to Dubai was 11 hours but on a brand new half full Airbus it wasn't so bad, even if we didn't get in early to move away from the bulk head seats. The leg room was handy while bubba was awake, but arm rests that don't fold up made it harder to get her to sleep.
I think though the most boring part was the 3 hour (more...)
Virtual Columns are really cool. I like them a lot. If you've never heard of them, shame on you, learn about them.
In short: a Virtual Column is not a real column, it's an expression that looks like a column... more or less.

It’s possible folks didn’t notice but Mac OS X no longer includes XQuartz by default from Maverick forward. You need to download XQuartz and install it. I’d recommend after you install Xcode.
Launch XQuartz and then either use the
bash shell it opens or open a Terminal
bash shell session. Inside the shell, you might start Secure Shell (
ssh) like this:
Mac-Pro-3:~ michaelmclaughlin$ ssh email@example.com firstname.lastname@example.org's password: (more...)
While working through getting my Mac OS X to work with X11, I stumbled on some interesting errors and misdirection solutions. Like most things, the solution was straightforward. Then, it struck me that I hadn’t installed it on my Fedora image. This blog post show you the errors I got the way to get it to work, and how to install X11 on Fedora.
The first step requires discovering the package. If you remember
Provisioning the server
First of all, we need a server to install the software on. There are many hosting providers that offer cheap Linux servers. I have been trying out (more...)
This is perhaps better explained with an illustration of the setup:
