Hey, another Web Server

Phusion Passenger is a web application server for multiple languages, including Ruby, Python and Node.js.

Desktop Info, the worthy successor to BGInfo

Admins like BGInfo for how it can show concise and important system info on the desktop.

But what it shows is static.  You really can't tell when the data on the screen was last updated.  It isn't very pretty, and customizing is less than ideal.

Drop BGInfo end go get Desktop Info, which shows real-time system information on your desktop.

It is lightweight, easy to customize, and supports multiple pages of information.  It even auto reloads the config file if you edit it. 

Get Desktop Info, you won't look back.

Here's a post on how to deploy it with GPO.
