Intel What's eating the battery life of my Linux laptop? Which software component causes the most power to be consumed? These are important questions without a good answer... until now. Intel announced the PowerTOP tool, a program that collects the various pieces of information from your system and presents an overview of how well your laptop is doing in terms of power savings. A number of apps, like Firefox, Evolution and Gaim have been modified by Intel to help consume less power and hopefully these patches will be integrated to their main trees or by distros.

Because noone thought about the power usage when programming the application?


I think it is more likely that at the time some of this code has been written there hadn't been any asynchronous method of doing the desired task.

For example take file change monitoring. If our operating system does not provide you a notification mechanism on file changes, you're only option left is to do polling.

Or RSS feeds: news aggregators have to poll their URIs since they can't just broadcast that they have new content available.
