Screencasts from the Italian Perl Workshop 2009

I’ve just been updating the page where I keep links to my presentations and noticed that, not only had I not updated the section for the 2009 Italian Perl Workshop, but I hadn’t even uploaded the screencasts I’d made.

So, with apologies for the delay, here’s my entry for IPW09, with the links to the uploaded screencasts:

had a great time at IPW08 and was delighted to be invited back for IPW09, which was another great success. My contributions were two talks. The first was called “DBI Oddmenti” and covered DBD::Gofer (16 minute screencast), DBI::Profiler (7 minute screencast), and DBDI a key component of a future DBI for Perl 6 (5 minute screencast). The second was “State-of-the-art Profiling with Devel::NYTProf” (40 minute screencast).

With 30 talks from 20 speakers on 2 tracks, IPW09 was another success for the Italian Perl Association, which was formally incorporated at the event. I’m confident that YAPC::EU 2010 is in safe hands.

I’m really looking forward to YAPC::EU. We’re combining the conference with our family summer holiday. We’ll be staying in a cottage in the village of Calci a few miles outside Pisa.

“Help Saving MySQL!”

Michael “Monty” Widenius, the creator of MySQL, has asked me, among many others, to help spread the word about an imminent decision by the European Commission on the Oracle merger with Sun.

Why should you care? Monty’s view, along with others, is that Oracle has much more to gain from neglecting MySQL than it has to gain from enhancing it.

Why should you act now? It seems that “Oracle has instead contacted hundreds of their big customers and asked them to write to the EC and require unconditional acceptance of the deal.” To balance this the European Commission needs to hear voices from the other side of the story. The European Commission is due to make a decision in just a couple of weeks.

What should you do? Read Monty’s post and act on it, if you so choose.

Wishlist of PL/Perl Enhancements for PostgreSQL 8.5

I’m working with PostgreSQL for my day job, and liking it.

We’re fairly heavy users of stored procedures implemented in PL/Perl, with ~10,000 lines in ~100 functions (some of which have bloated to painful proportions). This creates some interesting issues and challenges for us.

There’s a window of opportunity now to make improvements to PL/Perl for PostgreSQL 8.5. I’m planning to work with Andrew Dunstan to agree on a set of changes and develop the patches.

As a first step along that road I want to map out here the changes I’m thinking of and to ask for comments and suggestions.

The Voyage

We saw Johnny Duhan in a very small, intimate, concert in Ennis last year. Last weekend we saw Christy Moore in concert in Limerick. This song, written by Johnny Duhan and sung by Christy Moore, has always struck a cord with me.

I am a sailor, you’re my first mate
We signed on together, we coupled our fate
Hauled up our anchor, determined not to fail
For the hearts treasure, together we set sail

With no maps to guide us we steered our own course
Rode out the storms when the winds were gale force
Sat out the doldrums in patience and hope
Working together we learned how to cope

Chorus:
Life is an ocean and love is a boat
In troubled water that keeps us afloat
When we started the voyage, there was just me and you
Now gathered round us, we have our own crew

Together we’re in this relationship
We built it with care to last the whole trip
Our true destination’s not marked on any charts
We’re navigating to the shores of the heart

Chorus 2x

– Johnny Duhan

Here’s a video of Christy Moore and Johnny Duhan talking about the song and singing it together.

Perl Myths and Mongers in Dublin

Last weekend I went up to Dublin to speak at OSSBarcamp. I took the train from Limerick on Friday so I’d already be in Dublin the following morning, without having to get up at the crack of dawn.

Dublin.pm

Aidan Kehoe and I had a very small but interesting Dublin.pm meeting that night. Their first since 2004! Our wide-ranging discussions that night included me trying to understand what led Dublin.pm to flounder instead of flourish. I think a key factor was the (implicit?) expectation that members should make technical presentations.

Living in the west of Ireland there aren’t enough local Perl users (that I’ve found so far) to have a viable Perl Mongers group. So I setup the Limerick Open Source meetup instead.

Here’s what worked for us: We sit around in a quiet comfy hotel bar and chat. Naturally the chat tends towards the technical, and laptops are produced and turned around to illustrate a point or show results of a search, a chunk of video etc. There’s no set agenda, no declared topics, and no presentations. And yet, I think it’s fair to say, that everyone who’s come along has learnt interesting (albeit random) stuff.

I’d like to hear from perl mongers, in groups of all sizes, what kinds of balance between the social and technical aspects of Perl Mongers meetings works (or doesn’t work) for you.

OSSBarcamp

At OSSBarcamp I gave a ~15 minute ‘lightning talk’ on Devel::NYTProf in the morning, and a ~50 minute talk on Perl Myths in the afternoon.

The Perl Myths talk was a major update to my previous version, now over 18 months old, incorporating lots of updated graphs and other fresh information.

There is so much happy vibrant productive life in the Perl community that updating the presentation has been lovely experience. I keep having to revise the numbers on the slides upwards. There are lots of great graphs and they’re all going upwards too! (Many thanks to Barbie for the great new graphs of CPAN stats.)

I’ve put a PDF of the slides, with notes, on slideshare. Best viewed full-screen or downloaded.

I made a screencast but I think I’ll hang on to that until after I give the same talk, updated again, at the Italian Perl Workshop (IPW09) in Pisa in October — I’m really looking forward to that! I’ll make another screencast there and decide then which to upload.

After OSSBarcamp last week, and before IPW09 in late October, I’ll be flying to Moscow, visa permitting, to give a talk at the HighLoad++ (translated) conference. I’ve never been to Russia before so that’s going to be an amazing experience!
