March saw me spending rather little time on my Perl 6 grant. I merged various optimizations I developed during February, but held back to merge until after the March release in order that they could receive more testing before appearing in a release. I also did a few other minor optimizations, and fixed a performance regression introduced during a recent bug fix.

During March, I attended the German Perl Workshop. My talks included one on escape analysis, which I have been working on as part of this grant.

1:08 Test, re-benchmark, and merge optimizations developed

1:41 Investigate a performance regression arising from a
     BEGIN-time compilation bug fix, modify the fix

0:44 Analyze an increase in malloc/free churn during
     specialization code generation and avoid it
0:33 Shave a few more cycles off scalar dereferences
0:50 Issue and pull request triage

Google Summer of Code is making great progress. I appreciate everyone's help so far.

Separately, The Perl Foundation plans to participate in the first edition of Google Season of Docs. This initiative will fund writers to help improve the documentation of open source projects, and TPF will be applying to improve the documentation of the Perl 6 language. This documentation effort started in 2012 and is fully volunteer based. It's mostly complete and has proven to be helpful for new users, but it has got two main issues: getting updated for the 6.d release (November 2018) and tackle some gaps in the documentation of exceptions and precompilation.

TPF welcomes contributions to the documentation as well as all its other projects, inside or outside the Season of Docs.

If you are interested in participating as a writer or proposing new project ideas, check the season of docs site as well as Perl 6 documentation ideas site. Feel free to get in touch with JJ Merelo for questions.

Volunteers wanted

20th Year Anniversary Planning Lead
We're looking for volunteers who can help make the significance of the 20th Anniversary of Perl conferences stand-out! You don't need to have event planning experience to help out, but it is a plus if you have attended past Perl conferences. The Planning Lead will get to see their vision become a reality at #TPCiP and they'll get free admission to the event's main conference days!

YAPC 'regulars'
Are you a chronic attendee of Perl conferences? Have you been to almost every YAPC and TPC in America as an organizer, speaker, or attendee? We would love to hear from you!

Please send an email to [email protected] for more information about these opportunities.

We can't wait to see you back where it all began, in Pittsburgh, PA this June! #TPCiP

Bart received helpful comments on his blog posts last month that will move him ahead with intermediate representation (IR) optimization and register allocation.

He writes:

I'm still working on finalizing the floating point support for the JIT compiler, but I've also started work on the new register allocation algorithm. This wasn't strictly a deliverable, but I expect it will help the deliverable of improving code generation.

Grant Extension Approved: Tony Cook (Maintaining Perl 5)

I'm pleased to announce that the Board of Directors approved Tony's request for another $20,000. It will allow him to dedicate another 400 hours to this work.

I would like to thank the community members who took time to comment on this grant extension request and our sponsors who made funding the grant possible through the Perl 5 Core Maintenance Fund.

The White Camel Awards recognize outstanding, non-technical achievement in Perl. Started in 1999 by Perl mongers and later merged with The Perl Foundation, the awards committee selects three names from a long list of worthy Perl volunteers to recognize hard work in Perl Community, Perl Advocacy, and Perl User Groups. These awards have been managed by The Perl Review in conjunction with the The Perl Foundation.

For 2018, the White Camels recognize the efforts of these people whose hard work has made Perl and the Perl community a better place:

  • Perl Community - Todd Rinaldo, all sorts of things.

Todd Rinaldo has done plenty of technical work for Perl (you can blame him for taking . out of @INC), but's he's done quite a bit of non-technical work for the community as well. He's helped to organize Perl conferences and hackathons and provided other support through one of Perl's largest financial contributors, cPanel.

  • Perl Advocacy - David Farrell, for Perltricks and Perl.com

David Farrell started the PerlTricks.com site in 2013, then ressurrected Perl.com in 2017 (merging PerlTricks into it at the same time). He moved Perl.com to a GitHub repository that anyone can send pull requests to. Now it's easier than ever to not only create new content but update existing articles. He's also one of the co-organizers of the New York Perl mongers.

  • Perl User Groups - Max Maischein

Frankfurt.pm hosts the German and the Frankfurt Perl-Workshops and other special events (including YAPC::EU 2012). Max Maischein has been its treasurer since 2011, handling the accounting, reporting, and contracting, as well as coordinating work with other local organizations. Without that important work nothing could get done. He's part of the backbone of the German Perl community.

Congratulations to the 2018 winners!

Contributions to open source are largely in the form of code, as evidenced by the huge number of repos on github and distributions on CPAN. As we develop in public, users can see and recognize authors as they use the code. Community contributions can be less evident, and the White Camels were born as a way to recognize people who do non-technical work that can sometimes be less obvious and go unseen.

This year during the nomination process, there was some discussion about the focus of the White Camel and who is considered elegible. There was some confusion about technical vs. non-technical contributions of nominees with some feeling technical contributions should also be recognized in some form. There was also discussion about Perl 5 vs. Perl 6 contributions and whether that should be a consideration.

As with all things open source, the White Camels came from the community, and these are good discussions to continue as our community continues to evolve. Right now it's unclear what form the White Camels might take next year. The Perl Foundation will continue to support awards of some sort as a way to recognize contributors, typically through funding any costs associated with awards. Other leaders in the community will help determine what the awards might focus on, who we should recognize, and how. If you have new ideas for future awards or support continuing the White Camels as they are, we invite you to keep the discussion going.

The Grants Committee has concluded the voting of the November 2018 round.

There was one proposal this round, which was not approved.

This is a monthly report by Dave Mitchell on his grant under Perl 5 Core Maintenance Fund. We thank the TPF sponsors to make this grant possible.

The main thing I have been doing over the last month is fixing issues
related to smoke reports. In particular, I've been looking at Address
Sanitizer failures related to memory leaks.
