Where to Get Help - Linux Embedded systems

All software developers depend on little helpers, whether visible or invisible. Open Source developers tend to call upon a large number of resources to get help, very few of which require a contract or a well stocked bank account. we introduce a selection of them here to make your life a little easier, but please be aware of the fact that new resources are being created all the time. This is just meant to get you started.

University of Google

As far as we know, Google doesn’t have a university yet. But searching via Google seems to be the best first approach. When you search, make sure you take advantage both the web search and the newsgroup search. Google has an archive of newsgroup messages since before the advent of Linux. Many talented engineers share what they know through personal pages, project pages, and blog postings; and Google, as you know, is the perfect way to find this sort of information on the Web.

Some crafty web sites grab the contents of mailing lists and/or newsgroups and wrap them in a web page as a way of attracting visitors to their ad-laden slices of hell; they don’t have any better content than you find on a newsgroup, so feel free to look elsewhere.

Mailing Lists and Newsgroups

Mailing lists constitute the primary means of communication and serve as the mechanism of record for open source projects. A mailing list is nothing more than a system whereby communications are posted via e-mail and the postings are then forwarded to the list’s subscribers. The software managing the mailing list keeps an archive of the messages, usually grouped by month and then organized by topic.

Reading the archives is a great way to understand how people use the software you’re interested in and what sorts of problems are common.

You should also feel free to subscribe to the mailing lists of projects in which you have greater interest. To do this, you need to supply your e-mail address. Don’t worry about being spammed—these sites are run by people like you and aren’t interested in enhancing anything other than your technical knowledge. As a subscriber to the list, you can choose to receive messages as they’re posted or once a day, in digest mode. Digest mode is fine for occasional readers; but if you find yourself more involved in the project, once-a-day updates introduce too much latency.

For the newbie, the mailing list archives offer a wealth of knowledge. The open source community is large enough that somebody has worked through a problem like yours before. Google searches the mailing lists, but reading them directly gives you more context and understanding than reading a few messages in isolation. If you ask a question on the mailing list, you may get a reply that this has already been resolved or answered and a pointer to a URL of a message in the archives.
