The organizers of the past few conferences gave us some good data and some great advice, but prior to YAPC in Madison, there has been very little infrastructure handed down from one organizer to another. As we go into the home stretch before YAPC::NA 2012, our team will give a wealth of infrastructure to the next YAPC::NA organizers, whomever they may be. To them we leave behind:
With this post I am happy to announce the release of my new distribution: PerlGSL. This accompanies several other releases I’ve made in the past few days, I’ll get to those in a moment.
A few days ago I asked what I should call my new multidimensional integration module. The discussion centered on whether it was more important that it required the GSL library, or whether it was a set of bindings for the GSL (was that set complete)? Was it a dist in its own right needing a toplevel name, or that it was mathematical and should be under Math::?
After discussion and reflection, I have decided that I wanted a toplevel namespce for this project, mostly because the need to satisfy the external dependency on the GSL separates these modules from others. To make it worthy of that honor, I have made it into a dist in its own right, not unlike other named dists like Mojolicious or Catalyst, though more modular.

... and what happened?
I added a FAQ (Appendix F) page (and moved links to appendix H aka href appendix), but its just questions so far. You migth ask, but there is already a semiofficial FAQ. True. But would you not prefer better sorted anwers with links where all the parts of the answer are even better explained in more detail?
I added also a report.pl which gives you output like:
Just thought I’d share the Perl-inspired drink menu for The Perl Foundation party at YAPC::NA 2012.

London Perl Mongers organises technical meetings every two months. The technical meetings are a chance to find out what has been going on in the Perl community, what techniques people are using and how Perl integrates with other software.
The next technical meeting will be on the 31st May 2012 from 7pm to 9pm (you may arrive earlier, please sign in at the reception). You have to sign up to attend, see below.
This meeting is sponsored by Webfusion and will be held at the Conway Hall. Many thanks to Barbie, Webfusion and everyone involved for allowing us to use this wonderful venue.
The following speakers will present:
James Laver: Lovecraftian Perl
Paul LeoNerd Evans: Terminal Interface Construction KIT
Barbie: Labyrinth is/isn't a Web Framework
David Leadbeater: RE2: Faster regexp matching
For more information and to sign up, please visit http://londonpmtech.appspot.com/
See you there, Léon.
Unfortunately there's been very few talk submissions and registrations for NPW2012 so far which could be due to it being the week before YAPC::NA and a bit of tight schedule from announcement to workshop.
Therefore I'm considering rescheduling it for later this year.
Comments, thoughts?
I have completed the meat of a reasonably complete API wrapper for Reddit. You can grab it at https://github.com/jsober/Reddit-API.
It is pretty simple to use, and the docs are complete, but here is the gist:
I know that many of you are planning to set up these live streams of YAPC::NA 2012 in your offices and at home, so I wanted to get the URLs out to you so you can make sure you’re ready to go. Click here for the schedule.
You’ll need Microsoft Silverlight, Adobe Flash, or Apple Quicktime to be able to view these streams.
Please note that these streams are not live yet. They’ll go live at 9am US Central time on June 13th.

I'm writing an internal application using Dancer. To give it a "current" look, I'm using the Twitter Bootstrap CSS framework. A side effect is, that I wrote Dancer::Layout::Bootstrap, a set of Template Toolkit templates that import the Bootstrap layout into Dancer. I hope that this will evolve into a way to add external data files and maybe even layout templates to scaffolding frameworks such as Dancer.
Pretty Pictures
The demo application has a tiny bit of logic to demonstrate the effect of showing "flash messages" with Bootstrap, the green bar you see in the below image:
Firstly for this summary, I would like to extend a big thank to lestrrat, Mark Allen and Ron Savage for the first individual donations to the CPAN Testers Fund, as managed via the Enlightened Perl Organisation. The fund has been a long time coming, and we are really greatful to all the donations. If you'd like to contribute something to help CPAN testers, whether as a one-off or a regular contribution, please see the EPO CPAN Testers Fund page for further details. We plan to list all donators on the CPAN Testers Sponsors website, as a further thank you to you all.
In Chapter 3 of my book, I mentioned offhand that sometimes you expect the number 5, but you get 4.99999999998 instead. I sort of punted on the explanation because it seemed to be a touch of a distraction. Naturally, chromatic called me on that and suggested I explain a bit more. As part of my explanation, I wrote a sample program that would print out the fractions used to build the mantissa of a number. For example, .75 is 1/2 + 1/4.
We’d like to thank our sponsors for stepping up to support us. We really couldn’t do this without their support.
You too could sponsor YAPC.

I’m having a bit of a conundrum over where to put my next GSL-based module. First some background.
I’m already the author of a GSL-based module (see my first rant), the horribly named Math::GSLx::ODEIV2. This name reflects the same odd namespacing conundrum that I find myself in again, as well as the sub-library name odeiv2.c/h.
Duke Leto has already essentially taken the whole Math::GSL namespace by brute-force SWIG-ing the entire library. Much of this work is not fully implemented, but still parked. Further, since the namespace is already fairly crowded, its next to impossible to tell which parts are his and which would be anyone else’s. So lets call that out of the running. Note that I’m not complaining about his efforts, but it makes choosing a name harder.
After a hiatus of five and a half years, Acme::MetaSyntactic is finally back!
For this version, I have split the distribution in two:The main change is the creation of the Test::MetaSyntactic test module, that makes it much easier for theme authors to create their own theme distributions, and check that they follow the rules for Acme::MetaSyntactic themes.
Anyone willing to create new Acme::MetaSyntactic themes is invited to simply create
their own distribution (no need to send me patches any more!), and stick in a t/metasyntactic.t test file with the following content:
use Test::MetaSyntactic;
all_themes_ok();
Simply email me so that I can update the MetaSyntactic bundle.

When I first learned of Perl6 and D, They seemed to me to have similar sensibilities.
One of the motto’s of the Perl community is to “Make easy things easy and hard things possible”. I find it interesting that D actually does that to some extent. It has built-in resizeable arrays, and associative arrays for example.
Perl has always tried to shield the programmer from memory management. D also does that by having a garbage collector built into the language.
Neither language has been designed for complete backwards compatibility, because it has proven limiting in their respective ancestry. ( Perl4 -> Perl5 and C -> C++ )
Both Larry Wall and Walter Bright decided that different things should look different. This helps the compiler to parse them, but also helps the programmer to tell the difference.
I suggest that everyone who wants to learn a new programming language, learns both of them. Even though there is a large overlap in design ethos, they don’t have much overlap in actual design.
Of all the new languages, these two are the only ones that don’t feel like toys, or minor improvements of earlier languages.
You may or may not have heard that The Perl Foundation is throwing a private party after the banquet at YAPC::NA 2012.
We’ve shut down a local party spot for the night so that we can turn it into geek-space. Though it’s usually a hot college night club, on this one night only it’s going to feel more like a private Perl-only pub. Here’s what we’re doing to ensure a great party:
A recent test script of mine broke with the following message: You can only consume roles, MooseX::Role::Loggable is not a Moose role at /usr/lib/perl5/Moose/Util.pm line 137. What happened?
This test script uses Juno and an internal module that we have at work here. Both of them use Any::Moose. They also use my MooseX::Role::Loggable which uses Any::Moose as well, in order to allow you to use it in Moose and Mouse.
Hi Folks
Reluctantly, I've removed Locale::Country::SubCountry from CPAN, since I have no reasonable means of keeping the data up-to-date.
This data included subcountry names in the native scripts of the corresponding countries.
As a replacement, I spent a lot of time developing WWW::Scraper::Wikipedia::ISO3166. This (gently) scrapes country and subcountry names off Wikipedia, and stores them in an SQLite db.
The names are all use (more-or-less) latin letters (i.e. A-Z, a-z, with diacritics).
This is not my preference, but I've decided to adopt a policy of:
o Hoping ISO3166 is kept up-to-date (which is reasonable).
o Hoping someone, somewhere keeps Wikipedia up-to-date. I can't say whether or not this is reasonable, but I'm just going to assume it is.
I'll document various issues people might have with the Wikipedia/IS03166 version of such data.
A typical instance is the name of Bolivia:
o Wikipedia/ISO3166 calls it 'Bolivia, Plurinational State of' whereas you probably (and reaonably) expect it to be called 'Bolivia'.
Of course, Kim Ryan's module Locale::SubSountry, is always available, if mine provides data which fails to meet your expectations :-).
Cheers
Ron
So, I thought I'd contribute to moose.
A week ago I joined #moose and nopasted a public key. Cats and kids jumped all over me and I didn't follow through. In the end, I think that nobody acted on that. Today I thought I'd get back to that while the kids were out of the house. I still had the nopaste tab open, so pasted the URL and mst added my key.
