The Cattle Grid

It looks like we'll have at least 4 international speakers at this year's Italian Perl Workshop:

• Tim Bunce: creator of the Perl DBI interface. If you're a Perl coder, 99% chances are that you used DBI at least once. Tim is the architect of this great library, the abstraction layer which allows to communicate with almost all databases using a consistent interface. Tim Bunce is, however, not only related to DBI, but also to several other CPAN modules: the DBI driver for Oracle, Devel::NYTProf, etc. Moreover, he was the maintainer of Perl 5.4.x, he wrote some books for O'Reilly, and he's often a speaker at the major international open source conferences. To learn more about Tim: http://blog.timbunce.org/about/,

• Rafael Garcia-Suarez: lead developer of the current (5.10) release of the Perl interpreter More information here: http://consttype.blogspot.com/.

• Marcus Ramberg: Catalyst project leader. Catalyst can be regarded as the Perl killer application of these years. It's an open source framework for the development of web applications which closely follows the MVC architecture. It features a variety of experimental web patterns, and also implements some concepts which you can find in Ruby on Rails, Maypole and Spring. For more information: http://nordaaker.com/blog/

• Matt S Trout: DBIx::Class project founder, Catalyst core developer. DBIx::Class is one of the more widespread Object-Relational Mappers for the Perl language. More information about Matt is here: http://chainsawblues.vox.com/

Of course, besides these names, there are also many great Italian speakers. You can take a look at the workshop schedule.

So, don't miss Italian Perl Workshop 2008!!!

Rating: 4/5 (very good)

Amazon Web Services are a constantly expanding series of infrastructure services targeted to web developers who want to outsource parts of their application infrastructure. These services are meant to be reliable, scalable and cost-effective. Especially as far as reliability is concerned, however, Amazon Web Services - together with Google App Engine - have recently been regarded as a bit controversial, due to some downtime episodes. Nonetheless, services such as these provide a gate to the future of the Internet, where owners of small and medium web sites, who can't afford to build some high-quality services on their own, can easily outsource them.

Programming Amazon Web Services is the ideal primer to Amazon outsourcing services. It provides a general view of everything Amazon currently offers, including some services in the beta testing phase, as well as the necessary amount of in-depth coverage of each service.

A programmer who never outsourced any part of its infrastructure might not be much confident using APIs which abstract tasks such as database access and data storage (even though it would be a good practice to use some sort of API also for locally-provided services). To help in this situations, this book kicks off with an explanation on how to think an application, with an appreciated overview of REST-based APIs, remote requests and XML documents and their handling; at the same time, the author tells you how Amazon thinks you should build your application to effectively take advantage of what they provide.

After this introductory part, the whole book is dedicated to the exploration of each service: Simple Stoage Service (S3), Elastic Compute Cloud, Simple Queue Service, Flexible Payments Service and SimpleDB. Every section provides an explanation on what the service is and how it works, including not only its advantages but also the possible problems which may arise by using it. There's also some API references and, best of all, a lot of interesting code examples. Amazon Web Services can be used in any programming language so, even though the examples in this book are written in Ruby, it's easy to understand them and "port" them to your favourite language. Moreover, there are libraries around which allow a more abstracted usage of ABS: for instance, CPAN hosts several Amazon-related modules for the Perl language.

All in all, Programming Amazon Web Services this is a fine book for anyone who is seriously interested in using Amazon to outsource application infrastructure. Highly recommended.

I Perl Mongers italiani e il gruppo Pisa.pm sono lieti di annunciare il Quarto Perl Workshop Italiano.

Il Workshop si terrà a Pisa, nei locali messi gentilmente a disposizione dal Dipartimento di Informatica dell'Università di Pisa, nei giorni 18 e 19 Settembre 2008.

Il Workshop vuole essere un'occasione d'incontro rivolta a tutti gli utilizzatori di Perl, professionisti o amatoriali che siano, ma anche a chi si avvicina per la prima volta a questo linguaggio e ne vuole conoscere le particolarità e la cultura.

Accanto a interventi nel classico stile da conferenza, saranno previsti spazi di discussione e dibattito su argomenti di interesse, proposti dai partecipanti e guidati da esperti.

La partecipazione al workshop è gratuita, e include un servizio altrettanto gratuito di coffee-break.

Saranno inoltre disponibili a pagamento (incluse nel biglietto opzionale):

* T-Shirt dell'evento
* Gadget perl.it

Per maggiori info: http://www.perl.it/workshop

Fino al 20 Luglio 2008 sei ancora in tempo per proporre un intervento. Qui trovi tutte le informazioni per farlo:

http://conferences.yapceurope.org/ipw2008/cfp.html

Ti ricordiamo che la scadenza per l'invio di interventi è il 30 giugno 2008; inoltre, sebbene la partecipazione sia gratuita, ti chiediamo di registrarti quanto prima: questo ci aiuterà nella logistica!

Folks!

After some years of unsuccesful attempts, we finally managed to organise the Italian PerlHike. There were just 2 of us, but maybe it's promising for the future. ;-)

Here you can find a detailed story on the event (In Italian language), while some pictures are available at the following links (choose the format you like best):

I had the case of one of my PCs painted by a local artist, Giulia.
