Vista you start me up!
So some of us have moved to Windows Vista, a few teething problems but are please with some usability improvements.
For instance the most obvious to note is that you no longer have to start in order to 'shut down'.
As a user of Windows XP you had to select the 'Start' button to shut down the machine, which always seemed a bit of a misnomer to me. However Vista improves on this by only showing the icon button.
Windows XP - Start it up then Shut it down
Windows Vista - Shut down
Although I still found myself hunting the 'shut down' option and inadvertently selecting the globally recognised symbol for stand-by.

The efficiency of the tag cloud can be improved by applying colour ranges to match word frequency, as well as better use of text size. The article ("In search of the perfect Tag Cloud" looks at a number of sites with varying techniques.
Another way to quickly view tags by popularity is to filter them by a selected weight. Using the slider interface we can let the user quickly adjust the displayed tags.
Using a number of popular scripting libraries here is an example of our Tag Cloud filter.

Managing multiple onLoad events with Prototype
This is an update to a previous article written way back in 2003 "Managing multiple onLoad events in JavaScript".
The article describes how to create an array of onload (window.onload) events in order to queue each event and enable the browser to perform onload sequentially. However this can all be forgotten in preference to the Prototype Javascript Framework and the useful Event Observe method.
Use Event.observe instead of using <body onload="return myFunction()"> or DOM Level-0 event property window.onload = myFunction;
