  I've had a look at https://perl.petamem.com/docs/eng/reference/p5-modules/PDL.html - so far, it's barely a proof of concept, though that's not nothing. Based on my reading of the very early versions of PDL, your version looks like it hasn't broken past the 1996...

  First of all, congratulations on the major-version release! Have you ever taken a look at https://metacpan.org/pod/PDL::Transform::Color to compare and contrast with another module in a somewhat similar space? I'd be interested to help with interoperability and/or performance measurements :-)...

  To respond to MLX's thought, albeit a little while later: that would be more or less the "bundle" option. How it turned out: around the end of 2024, PDL 2.096 was released. In the months beforehand, various modules that had...

• Posted PDL 2.063_01 released to Ed J

  There have been a couple of developments in PDL since the last announcement on here I could find, from 2013. To hypersummarise: 64-bit indexing, native complex number support, automatic pthreading using all available CPU cores, faster installation thanks to parallel-building, memory-mapped data,…

• Posted graphql-perl - plugin to make GraphQL "just work" with Mojo publish/subscribe functionality to Ed J

  GraphQL is the new, shiny way to do APIs. It minimises number of round-trips for clients to query what need. But what about real-time updates? How can we cut down the time needed for clients to get new information? Are we forcing them to constantly poll? That seems expensive and also slow.

• Posted Test::Snapshot - automate externalising "expected" data to Ed J

  During the ongoing development of graphql-perl, I have found it valuable to generate data structures, and to compare those with expected values. Often, these have been highly detailed rather than a subset, because I wanted to know when anything changed.

• lichtkind commented on Graphics::Toolkit::Color 2.0 feature overview

  Performance is not a topic i am concerned (yet) and I know its not the fastest module. Just fast enough for normal usage and since there are no dependencies, we do fine. but on the other side the hardest math it does is vector x 2x3 Matrix and the only thing i can currently do to make it faster is doing the automatic translating into color names lazily.

• PetaMem commented on PDL in Rust -- A Native Reimplementation of the Perl Data Language

  So you are in a quantum superposition of being both interested and not interested. Congrats, but let me collapse your wave function.

  a) Who says "without PDL::PP"? That might have been true 3 days ago.

  b) You should know, Mohawk, that these blog entries are kind of a heads up to the beloved Perl community. Things are moving very fast these days. 3 days ago maybe 1996, today 2027 (if PDL 3.x will have autoparallelization by then) who knows what will be next week.

  c) Looking at the reference docs... that mostly point you to the original documentation ... I'm impressed b…

• PetaMem commented on PDL in Rust -- Part Two

  Before the technical points: the framing of this comment - “only have your word”, “your AIs”, a string of tasks described as PRs you expect us to deliver - is not a frame we will work inside. I will answer the substantive questions below in good faith. Further engagement in this register, from anyone, will be met with silence; comments asked in good faith will continue to get answers.

  On the numbers. The harness that produced them is part of the pperl repository. More directly useful: we are preparing a short how-to for runnin…

• Aristotle commented on The AI Revolution is Validating 40 Years of Perl Philosophy

  Also in at least two cases the wine glasses are in an ambiguous position in space, both in someone’s hand and in front of that hand simultaneously, or possibly having some fingers fused with the stem.

  Also, if you zoom in you will notice that basically no two people are looking actually at each other – almost everyone is looking just past the temple of the person near them, as if they are all standing staggered by half a shoulder width. (Maybe that is why they seemingly need so little personal space, because they’re not in fact up in each others’ faces?)
