+A little web application for keeping an eye on things
+======================================================
+
+There are a lot of things I'd keep an eye on, if it was easier,
+including:
+
+- Nagios problem summaries
+- Various plots showing metrics for our hosted applications
+- finance.google.com
+- social network feeds
+- ...
+
+I could keep web pages open, but that takes too much space.
+
+What I want is the equivalent of an electronic photo frame for web
+pages.
+
+I decided to throw something together today that would do this for me:
+
+   http://www.riversnake.com/webframe
+
+This is a purely client side application that collects URLs and
+cycles through them, staying on each one for a minute at a time.  You
+can add, list and remove URLs.  You can stop and start cycling, move
+forward and back, and select URLs to display.
+
+There are a few interesting things to note:
+
+Web Storage
+  The localStorage facility provided by modern browsers is used to
+  store the list of URLs.  The storage is keyed on the URL, so you can
+  keep multiple lists of URLs by adding query strings (or copying the
+  application to other URLs).
+
+Layout
+  The application has a row of controls across the top and an iframe
+  that takes up the rest of the page.  Getting the iframe to fill the
+  remainder of the page, and getting the URL bar at the top to fill
+  the middle of the control bar was a bit tricky.  Using CSS
+  percentage based sizes wasn't acceptable because I didn't want to
+  scale all components equally when resizing a page (or when zooming
+  in or out).
+
+  The most common technique seems to be to use javascript handlers for
+  page resizes to resize the page contents.  Dojo, which I used for
+  the control widgets has some mechanisms to do this, but I wanted to
+  see if I could manage it totally with CSS.
+
+  I ended up using a combination of absolute and fixed positioning
+  expressed in terms of ems. See the CSS styles in the HTML for more
+  information.
+
+Unicode Fun
+  I was too lazy to go scrounge up images to use for the player
+  controls, so I ended up using unicode text that got be close
+  enough. :)
