If you’re getting the “Can’t locate Catalyst/Engine/HTTP/Restarter.pm” error message, it is very likely you’re running a recent version of Catalyst:

The problem is that Catalyst::Engine::HTTP::Restarter within Catalyst::Engine was replaced by Catalyst::Restarter within the Catalyst::Devel package. How to fix your application to use the updated development web server? Very easy. Rerun catalyst.pl with the “-scripts”, to rebuild just the scripts in the script directory, and “-force” to overwrite any files therein:
jason@catalyst:~/catalyst-book-code/Chapter_3$ catalyst.pl -scripts -force LolCatalyst::Lite
exists "LolCatalyst-Lite/script/lolcatalyst_lite_cgi.pl"
created "LolCatalyst-Lite/script/lolcatalyst_lite_cgi.pl"

If you’re interested in learning the Catalyst Web Framework (Perl based), I highly recommend The Definitive Guide to Catalyst: Writing Extensible, Scalable and Maintainable Perl–Based Web Applications
When I 
purchased Foundations of Qt Development (Expert’s Voice in Open Source) by Johan Thelin
Foundations of Qt® Development (Expert’s Voice in Open Source)
What I really like is that when he shows you an example of code, he explains why you would want to write it this way and how it differs from the Standard Template Language (STL – see C++ Programming Language, The (3rd Edition)
I never realized just how easy it is to write C++ using the Qt framework! Just the Signals and Slots alone make it very very powerful and that’s just the beginning. I’m completely blown away 
If you’ve been following the Wheel of Time series by Robert Jordan, you would know that the last “book” will be released in three separate volumes. Why? Because there is just so many plots and subplots and subsub plots and subsubsub plots …. plots to wrap up.

The Gathering Storm
Brandon Sanderson will be taking over writing the last book as Robert Jordan died last year. See the full size cover over at Dragonmount. It will be released on November 3rd of this year (2009).
