<chapter name="Support">
<p/>
One of the major features of Open Source projects is the technical
support. Articles in the mass media often criticize open source
efforts for not having the same tech support that a commercial product
has.
And boy is that a good thing! Instead of dialing up some overworked
and understaffed help desk and being treated to Music On Hold for an
hour or so <em>without</em> ever getting the answer you need, we have a
better solution: the Ruby community. The author of Ruby, the authors
of this book, and many other Ruby users are
willing and able to lend you a hand, should you need it.
<p/>
The syntax of Ruby remains fairly stable, but as with all
evolving software, new features are added every now and again. As a
result, both printed books and the online documentation can fall
behind. All software has bugs, and Ruby is no exception. There
aren't many, but they do crop up. See the bug reporting section
on page 533 for details.
<p/>
If you experience a problem with Ruby, feel free to ask in the mailing
lists or on the newsgroup (more on those in just a minute). Generally
you'll get timely answers from Matz himself, the author of the
language, from other gurus, and from those who've solved problems
similar to your own.
<p/>
There might be similar questions in the mailing lists or on the
newsgroup, and it is good ``netiquette'' to read through recent postings
before asking. If you can't find the answer you need, ask, and a
correct answer will usually show up with remarkable speed and
precision.
<section>Web Sites</section>
<p/>
The official Ruby Home Page is <url>http://www.ruby-lang.org</url>.
<p/>
You can also find Ruby information at
<url>http://www.rubycentral.com</url>. In particular, you'll find
complete online references to Ruby's built-in classes and modules at
<url>http://www.rubycentral.com/ref/</url>, and to the Ruby FAQ at
<url>http://www.rubycentral.com/faq/</url>.
<p/>
While you're surfing, drop in on
<url>http://www.pragmaticprogrammer.com</url> and see what we're up to.
<section>Download Sites</section>
<p/>
The latest version of Ruby can be downloaded from:
<url>http://www.ruby-lang.org/en/download.html</url>.
<p/>
Mirror sites are:
<p/>
<ul>
<li> <url>ftp://ftp.TokyoNet.AD.JP/pub/misc/ruby</url>
</li><li> <url>ftp://ftp.iij.ad.jp/pub/lang/ruby</url>
</li><li> <url>ftp://blade.nagaokaut.ac.jp/pub/lang/ruby</url>
</li><li> <url>ftp://ftp.krnet.ne.jp/pub/ruby</url>
</li><li> <url>ftp://mirror.nucba.ac.jp/mirror/ruby</url>
</li><li> <url>http://mirror.nucba.ac.jp/mirror/ruby</url>
</li></ul>
<p/>
Precompiled Windows binaries (using cygwin) are in the
<tt>pc/</tt> subdirectory.
<section>Usenet Newsgroup</section>
<p/>
Ruby has its own newsgroup, <tt>comp.lang.ruby</tt>. Traffic on this group
is archived and mirrored to the <tt>ruby-talk</tt> mailing list.
<section>Mailing Lists</section>
<p/>
There are five mailing lists now talking about Ruby. The first is in
English, the last four in Japanese:
<p/>
<table>
<p/>
<toprule/><tr>
<td><tt>ruby-talk@netlab.co.jp</tt></td>
<td>English language discussion of Ruby
(mirrored to <tt>comp.lang.ruby</tt>).</td>
</tr>
<tr>
<td><tt>ruby-list@netlab.co.jp</tt></td>
<td>Japanese language discussion of Ruby.</td>
</tr>
<tr>
<td><tt>ruby-dev@netlab.co.jp</tt></td>
<td>List for Ruby developers.</td>
</tr>
<tr>
<td><tt>ruby-ext@netlab.co.jp</tt></td>
<td>List for people writing extensions for or with Ruby.</td>
</tr>
<tr>
<td><tt>ruby-math@netlab.co.jp</tt></td>
<td>Ruby in mathematics.</td>
</tr>
<bottomrule/></table>
<p/>
See <url>http://www.ruby-lang.org/en/ml.html</url> for details on joining a
mailing list.
<p/>
The mailing lists are archived, and can be searched using
<url>http://blade.nagaokaut.ac.jp/ruby/ruby-talk/index.shtml</url>.
<section>Bug Reporting</section>
<p/>
If you think you've spotted a bug in Ruby, you may want to browse the
bug database at <url>http://www.ruby-lang.org/cgi-bin/ruby-bugs</url>.
You may also want to check to see if a new version of Ruby is
available---perhaps the bug you've found has already been fixed.
<p/>
You can submit a bug report either by using the Web page mentioned above
or by sending an e-mail to <tt>ruby-bugs@ruby-lang.org</tt>.
<p/>
When reporting a suspected bug, it would be a good idea to include the
output of ``<tt>ruby<nbsp/>-v</tt>'' along with any problematic source code.
People will also need to know the operating system you're running. If
you compiled your own version of Ruby, it might be a good idea to
attach your <tt>rbconfig.rb</tt> file as well.
<p/>
If you have a problem using irb, be aware of its limitations (see the
reference section beginning on page 523). See what happens
using just Ruby itself.
