Hello, readers of the weekly Linux newsletter.

Your editor had a thought today. There are dozens and perhaps hundreds of
small companies that support and customize software built on free and open
source projects. Those companies serve plenty of customers who aren't
necessarily part of the greater free and open source software communities,
but they benefit greatly from the work of people in those communities.

Is it possible to bring those companies into the communities and, with
them, their customers and partners?

Obviously, your editor wants to widen his company's audience too--but
could this be good for everyone?

It was an interesting thought and seems worth further study.

Once you've made the choice to create good documentation for your project,
you face the embarrassing risk of having bugs, typos, and bad advice in
the documentation. Everyone knows by now that rigorous testing can help
reduce the occurrence of defects in software (even if not everyone does
it). The same principle applies to documentation, with a little bit of
care. Leonard Richardson shares how he and Lucas Carlson verified the
code in the new "Ruby Cookbook" with a technique that works for any sort
of technical writing:

Loops are difficult in SQL. If you need to perform any sort of batch
operation over a list of data with plain SQL, it's likely that you'll need
some sort of procedural wrapper to make everything work correctly. An
alternative is to use embedded functions and stored procedures to perform
your batch operations. David Wheeler shows how to do exactly that in
PostgreSQL and PL/pgSQL:

In weblogs this week, Dave Cross summarized his experiences at YAPC::EU,
the grassroots European Perl conference:
