5th May 2009

This months North West England Perl Mongers technical meeting is in Manchester at the Manchester Digital Development Agency starting at 18:30. All three talks will be around 20 minutes long.

Object oriented database design in PostgreSQL

Matt Trout, Shadowcat Systems.

Applications often need is-a as well as has-a relationships in order to properly model the business domain. This talk describes:

Converting 16k user mailboxes from MBOX to MDIR++

Ian Norton, Lancaster University.

Converting a legacy mail system has many challenges, turn that into fifteen year old data and upwards of 16k mailboxes and you have quite a substantial headache. On a system melting under IO load and providing an ever decreasing level of service, we needed to dig it out of a hole and fix it properly. With no major outage. While people were still accessing their email.

Functional Pe(a)rls v2 (now with Monads!)


Yes, functional programming is useful in Perl already but it isn't always pretty. I'll show a selection of techniques from FP languages, and also ways to make them pretty and Perlish. Including:

We'll use some shiny new Perl toys (like Devel::Declare) to help us get convenient syntax for these techniques.

The meeting will be followed by drinks at The Salisbury pub next to Oxford Road station from around 20:00. Someone will be carrying a Pingu if you're trying to find us!

Remember, North West England Perl Mongers covers the largest geographical area for any Perl Mongers group in the world! If you want us to bring the camel and penguin to your area and you can organise a venue, please do let us know.
