List::Gen revivified

    After more than ten years of hibernation I was able to waken List::Gen and fix some tests that failed since v5.19 including "fails on bleadperl" and a reported bug "primes incorrect for 664580, and slow".

    The new version is currently available on my github repo only, as the author is not responding. Does anybody have information about "Eric Strom" aka "ASG"? Otherwise I might try to get an indexing permission on CPAN as a co-maintainer, though I'm clueless regarding this process.

    We're happy to confirm the venue and date of this year's London Perl & Raku Workshop.

    When: Saturday 26th October 2024
    Where: The Trampery, 239 Old Street, London EC1V 9EY

    This year's workshop will be held at The Trampery, at Old Street. A dedicated modern event space in central London. We have hired both The Ballroom and The Library; allowing us to run a main track for up to 160 attendees, and second smaller track for up to 35 attendees.

    The Trampery in Old Street is located a two minute walk from the Northern Line's Old Street tube station in central London. The Northern Line has stops at most of the major train stations in London, or trivial links to others, so we recommend taking the tube to get to the venue.

    If you haven't already, please signup and submit talks using the official workshop site: https://act.yapc.eu/lpw2024/

    Thanks to this year's sponsors, without whom LPW would not happen:

    If you would like to sponsor LPW then please have a look at the options here: https://act.yapc.eu/lpw2024/sponsoring.html

    The London Perl & Raku Workshop (LPW) will take place this year on Saturday 26th October and you are encouraged to submit your talk proposals now. We have already had 30 registrations for the workshop so we anticipate a good turnout this year.

    We welcome proposals relating to Perl 5, Raku, other languages, and supporting technologies. We may even have space for a couple of talks entirely tangential as we are close to finalising the venue (very central London) and should have room for two tracks.

    Talks may be long (40mins), short (20 mins), or very short (aka lightning, 5 mins) but we would prefer talks to be on the shorter side and will likely prioritise 20min talks. We would also be pleased to accept proposals for tutorials and discussions. The deadline for submissions is 30th September.

    We would really like to have more first time speakers. If you’d like help with a talk proposal, and/or the talk itself, let us know - we’ve got people happy to be your talk buddy!

    Register (it's free!) and submit your talk on the workshop site.

    We would also like to make a call for sponsors - does your company want to support the workshop? By sponsoring LPW you can demonstrate your support for the Perl and/or Raku languages and nurture your relationship with the local developer community. Much more information can be found on the workshop site along with a sponsor prospectus.

    As well as the benefits as listed on the aforementioned page, sponsors will all feature in blog posts, news posts, social media posts. That starts right now, with our first sponsors who have already generously sponsored the workshop:

    With thanks from The London Perl & Raku Workshop 2024 organising team.

Call for TPRC Volunteers

    From Sarah Gray comes the following announcement about the upcoming Perl and Raku Conference in Las Vegas, NV:

      We hope you are coming to The Perl and Raku Conference in Las Vegas June 24-28!

      Plans are underway for a wonderful TPRC. But a conference of this type is only possible because of volunteers who give their time and expertise to plan, promote, and execute every detail.

      We need volunteers!

      You may have already volunteered to speak at the conference; if so, wonderful!

      If you are not presenting (or even if you are), there are many ways to help. We need people to set up and take down, to run the registration desk, to serve as room monitors, to help record the talks, and to just be extra hands. If you can spare some of your time for the sake of the conference, please fill out a volunteer form here.

      We also welcome spouses and friends of attendees who might be coming along to Las Vegas to share the experience. We are offering TPRC "companion" tickets, for access to the social parts of the conference (food, drink, parties) but not the technical. Volunteers of at least one complete day, who sign up before the conference, will have companion access "comped".

      If you have questions about volunteering, please contact our TPRC Volunteer Coordinator:

      Sarah Gray <sarah.gray at pobox.com>

    Edit: Fixed some typos

    Thanks PJ. We owe you so much. Groklaw -- RIP -- 2003 to 2013.

    Apparently we forgot to announce the GPW24 in Frankfurt, the same way we did before...

    So time to at least denounce it now. ;-)

    It was great again:

    • 20% more attendants than the year before
    • interesting talks, especially about AI
    • Sleep inducing oxygen deprivation, till we managed to regularly open the windows
    • International guest-speakers: Indians from India, Americans from France, Ukrainians from Finland, Kiwis from Germany, Germans from London, Brits from Alpine State-lets and ... Bavarians ... ;-)
    Thanks to for organizing :)))

    And sorry for everyone I missed denouncing!

    See you next year in Munich.

    Cheers Rolf
    (addicted to the Perl Programming Language :)
    see Wikisyntax for the Monastery

    PS: Apparently there is still a huge (200+ attendants) YAPC happening in Japan each year, would be nice to connect here (or anywhere else) ...

The Perl and Raku Conference: Call for Speakers Renewed

    The Perl and Raku Conference is fast approaching! We will be in Las Vegas on June 24-28, (main conference June 25-27). We want more speakers, so we are reopening the full call for talks/papers/posters.

    The new deadline is April 20, midnight Las Vegas time. (April 21 00:00 UTC) (April 21 07:00 UTC)

    Now that the eclipse is not a distraction, please consider submitting a talk (50 minute, or 20 minute) or a scientific paper or poster before that deadline! Link to conference website Speakers will be informed of talk acceptance by April 30. Whether speaker or attendee, we look forward to seeing you in Las Vegas!

    Nota Bene: 20m talks, 50m talks, papers, and posters earn free admission for the presenter. Giving a Lightning Talk does not reduce the admission fee, but earns our appreciation and delight!

    Update on 2024-0418: Jeepers. Kids, don't play with time zones. There are so many ways to get them wrong. Thanks to LanX.

    Alex / talexb / Toronto

    Thanks PJ. We owe you so much. Groklaw -- RIP -- 2003 to 2013.

PDL 2.087 released and a summary of a ~year of PDL

    Crossposted from https://www.reddit.com/r/perl/comments/1by46uj/pdl_2087_released_and_a_summary_of_a_year_of_pdl/.

    A new release of PDL is out! It’s been about a year since I last posted on here about a PDL release (last was PDL 2.083).

    A selection of changes since PDL 2.083:

    • Diab Jerius reported that a previous change to [xyz]vals to return at least a double had a regression for code that requests an explicit type smaller than that. Fixed in 2.085.

      Diab Jerius also reported several other edge cases: 1, 2, 3 including a fix for vsearch.

      Also, Diab Jerius modularised the primitive ops tests which allows for faster parallel testing.

    • Harald Jörg reported that large arrays would cause PDL::FFT to crash. Fixed by switching from the stack VLAs to heap allocation. Fixed in 2.085.

      While it is recommended to use PDL::FFTW3 instead, PDL::FFT is bundled with PDL for the cases where PDL::FFTW3 can not be easily installed.

    • Bas Couwenberg reported and fixed a previously deprecated API in HDF4 which has now been removed and replaced. Fixed in 2.085.

      As part of the Debian release process, Bas Couwenberg reported a failure on i386. Fixed in 2.087.

    • Shawn Laffan provided an improvement to PDL::GIS::Proj so that it would load correctly on Windows via Alien::proj.

    • Po-Chuan Hsieh provided a build fix for FreeBSD on amd64. I also happened to talk to James E Keenan around the same time about PDL builds on FreeBSD so this was followed up by adding CI testing for FreeBSD. Fixed in 2.085.

    • Ryan Egesdahl provided a fix for macOS Ventura which changed the location of GLUT headers. Fixed in 2.085.

    • Eli Schwartz reported an upstream Gentoo bug when building with LTO that uncovered 64-bit issues in Minuit and Slatec Fortran code. Fixed in 2.086.

    • @vadim-160102 reported several issues with stringification: 1, 2; one of which uncovered a bug in conversion of ulonglong to Perl scalar.

    • Karl Glazebrook, @vadim-160102, and users from PerlMonks provided valuable reports in tracking down issues with dataflow https://github.com/PDLPorters/pdl/issues/461. Fix available in 2.086.

    • Jörg Sommrey contributed improved typemap handling which allows for using the typemap definitions that are available in Perl’s default typemap. Available in 2.086.

    • Ed has added many improvements to the PP code generator and internal API as well as several new functions. Please see the Changes file for details!

      Of note are several speed improvements that are inspired by Eric Wheeler’s note about the speed of sequence().

    A full list of closed issues and PRs is here. Thanks to all the contributors!

    There are also some things to report from the wider World of PDL:

    • Jörg Sommrey has released a PDL interface to GLPK (GNU Linear Programming Kit) for mathematical optimization: https://metacpan.org/pod/PDL::Opt::GLPK.

    • The PGPLOT distribution now incorporates PDL::Graphics::PGPLOT module that was in the PDL distribution. The dependencies remain the same.

    • PDL::Graphics::Simple had some small updates to the drivers. This is preparation for splitting the backend engines to their respective backend distributions (not yet released) and defining an API version that the engines conform to.

    PDL 2.085_02 has just been released. Notable changes since 2.083:
    • Dataflow bugs have been fixed (GH#461)
    • Dimension-checking for inputs and outputs are now rigorous to stop accidentally writing to the same place several times (GH#445)
    • PDL::Graphics::PGPLOT has been moved into the PGPLOT CPAN distro and out of main-PDL
    • Speed improvements (GH#451)
    • A 20-year-old bug in rangeb has been fixed thanks to jo37

    Thank you to all those who reported bugs or unexpected behaviour, or ask why something or other isn't possible: you help make PDL better and better!

    The IRC channel (#pdl on irc.perl.org) is a great virtual place to come and ask questions, or just watch the GitHub messages flow by.

    Please give the new release a try and report problems.

Registration for The Perl and Raku Conference 2024 is open!

    The Perl and Raku Conference (formerly known as YAPC::NA) is going strong!

    This year, we are celebrating 25 years, our silver anniversary, in the Silver State, Nevada! The main conference will be in Las Vegas on June 25-27, but there will be hackathons and possibly classes on the day before and the day after the conference (June 24th and 28th), so please consider joining us for the whole week!

    The backbone of this conference has always been our tracks of "traditional" talks by community members and what we have come to call the "Hallway Track", the informal exchange of ideas and camaraderie that sparks new projects and fuels collaboration.

    This year, we are pleased also to host the presentation of Papers and Posters accepted by the Science Perl Journal!

    Go now to https://tprc.us/ to check out what is planned and to book a room (see link to Alexis Park Resort under "Location"). Rooms start at only $75 per night, so it’s worth booking early!

    The best way to register for the conference is here.

    Alex / talexb / Toronto

    Thanks PJ. We owe you so much. Groklaw -- RIP -- 2003 to 2013.
