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.

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!

Perl in five sentences

I just added a concluding slide to my updated Perl Myths talk. Having comprehensively debunked some myths with hard facts about perl and its ecosystem, I wanted to end with a slide that summarized some truths.

I liked the slide text so much I wanted to share it with you:



Perl:

has a massive library of reusable code
has a culture of best practice and testing
has a happy welcoming growing community
has a great future in Perl 5 and Perl 6
is a great language for getting your job done
    for the last 20 years, and the next 20!

 


It would make more sense after seeing the talk, but I think it stands well on its own as a summary of Perl.

Is your Perl community visible?

As I mentioned recently, I’m working on an update to my Perl Myths talk. (Which is really a review of the state of the art, state of the community, resources, and best practices. You could even call it marketing.)

In recent months, and especially while researching for this update, it’s become clear to me that the Perl community is both functioning well and growing more conscious of its own role and value.

But are the various components of “the community” sufficiently visible? Continue reading

NYTProf v3 – a sneak peak

I’ve had a great week at OSCON. The talks are excellent but the real value is in the relationships formed and renewed in the “hallway track”. I’m honoured and humbled to be able to call many great people my friends.

My talk on Devel::NYTProf seemed to go well. This year I covered not just NYTProf and the new features in v3 (not yet released) but also added a section on how to use NYTProf to optimize your perl code.

Here’s a quick summary, with links to the slides and screen-cast, and outline what’s still to be done before v3 gets released (getting closer by the day). Continue reading
