But after the guess is make the host of the game opens one of the two remaining doors, showing no prize behind it. The question is should the contestant change his guess from the original door to the remaining closed door.

So, in ditching Windows I had to find a solution to my Windows-based X-10 home automation. On Windows I had a CM19a USB based transceiver for issuing X-10 commands to the X-10 modules controlling my house lights. I used a piece of software named Alex10 to command the CM19a, and a Philips Hue Bridge emulator (HA-Bridge) to allow me to give voice commands via my Amazon Echo.

The HA-Bridge software was a Java program with a web interface, so it ported over cleanly from Windows to Linux. What I had to find was something to replace the Alex10 software. Searching the Internet I found some software that did exactly what I needed, Mochad.

I finally decided to drop Windows from all of my home computers (currently three systems) and move them all over to Linux. I had already moved two of them, one that I use for a home theater, and one I use for general work. The third was being used for general work and for controlling my old home automation system.

Early in my career, when I was working on Unix systems I started collecting fortunes, quotations, etc and put them into a “fortune” program. Click the button below to see a new fortune.

In 2013, when I was working with HB Design, I had my personal website hosted on a company web server. That server that was used for hosting employee websites has long since been decommission, and between that and my retirement the HTML table generator web tool that I wrote disappeared.

Now with my new site up I found that the link to the table generator was broken. After looking through all of my backups and archive files, and not finding the code, I decided to try the Way Back Machine and I found the code. Which illustrates how hard it is to lose a web page on the internet.

I was able to copy the source code off the Way Back Machine and, with some simple edits to remove code that the Way Back Machine inserted into the archived page, was able to recreate the tool on this web site.

I just setup WordPress on Amazons EC2 service. I didn’t find a good set of instructions on how to do it, but pieced together the following from various sources. Note that my PC is Linux based.
