Arduino to the rescue.

You can get add on boards to make your Arduino more functional. Seeed (available at Radio Shack and other fine companies) makes several boards that are price competive.)   I bought the Seeed ethernet add-on board for half the price of the Arduino option, but it was a bit trimed down such as no card slot. The board also works with the Osepp Arduino clones. That is what we used for this project.


 


I wanted a way to have a temporary web server up when I needed to bring the regular web server down.  The Arduino was the perfect choice. I just took the web server example from the Arduino IDE and commented out the code that was not needed (but could be reused later) and added the code that was needed i.e.


...
          client.println("<center>");

          client.println("<h1>Your server name<h1>");
          client.println("<hr");
          client.println("<br />");

          client.println("<h2>Bear with us as the server is under reconstruction!</h2>");
          client.println("<img src='http://www.seemyheart.org/wp-content/uploads/2013/06/Website_Under_Construction.gif' height=500 width=500 />");
          client.println("</center>");
...

Now I have a way to keep a web presence if I need to alter the server for a short period of time without the usual web page being up. Our Arduinos:

You actually can do a minimal windowing from the command line in Linux with dvtm. Dvtm is excellent for low end machines where graphics are not a priority. In the picture shown we have a working clock, SC a spreadsheet that you can easily export data to your favorite desktop spreadsheet such as Libreoffice, Links2 a web browser pointed to www.google.com, and finally nano a pretty decent basic text editor. I prefer vim, but nano has more of a user interface. Cheatsheet: `dvtm` is one simple, easy-to-use terminal multiplexer. Commonly used Options:     -v         prints version information to standard output, then exits.         -m <mod>   set default modifier at runtime.         [cmd...]   Execute cmd after dvtm is started. KeyBoard Shortcuts:     Mod    Each keybinding begins with Mod which defaults to ^g but can  be               changed in config.h or with the -m command line option.                       Mod-c  Create a new shell window.            Mod-x  Cl

Web.com and Network Solutions, the Walmart of the internet.

Web.com bought Network Solutions last month, and also has bought Register.com . Web.com picked up Network Solutions for $405M plus some stock. I have been using an e-commerce package form Network Solution for two years. I wouldn’t have noticed the buy out as the Network Solutions site has not changed. A couple of weeks ago I noticed that Network Solutions was offering some new products such as Gorilla Online Marketing . Soon after that we received a sales call about Gorilla Online Marketing from Network Solutions. When I returned the call the phone was answered by Register.com, I was confused at first but quickly found out about the buy outs. They seem like a good fit, they all target the same types of small to medium size businesses. Network Solution has always had great customer support in my opinion. Their sales people are a little irritating sometimes but they beat the heck out of GoDaddy.com and Comodo.com and you can’t beat the prices. If you can beat the prices ask them for a
