Here is an outline for a presentation on the status of embedded Linux:

This is essentially User:Tim Bird's private collection of interesting notes about the status of embedded Linux. It tends to get updated right before a Linux conference.

NEWS: Tim Bird's Status of Embedded Linux (October 2009) presentation, which he delivered at the Japan Linux Symposium, is now available.


Process for adding information

Anyone can add information to this page. I used to maintain the information at the Technology Watch List, but the table format there is a bit constrictive. (It would be nice if MediaWiki had a table editor!!)

Since I have to form this stuff into a "State of Embedded Linux" presentation several times a year, keeping the information in wiki outline format is convenient for me. It's easier to put directly into a presentation.

Please place information in bullet form, with a link to a supporting article, in the appropriate sub-section below.

Page History

I'll let MediaWiki store historical versions of this page. If you want to see what the hot issues were from a last year or a few years ago, please see look at the page history. (Although, updates of this page have historically been a bit spotty).
