• Commented on Enter the Matrix ... with PDL
  Whoops! That should be: ($xmesh, $ymesh) = meshgrid($x, $y); $C = 1/($xmesh - $ymesh); See https://metacpan.org/pod/PDL::Slices#meshgrid for more....
• Commented on Enter the Matrix ... with PDL
  This would be super-easy - indeed, barely even an inconvenience - with the relatively-recently cribbed-from-MATLAB meshgrid. $C = 1/meshgrid($x, $y)...

• Commented on k-means: a brief interlude into Data Wrangling
  Hi, I'd have reached out to you by email or GitHub but I can't figure out your ID. If you'd like to help with PDL communication, maybe making a PDL Advent calendar posting, then please comment on https://github.com/PDLPorters/pdl/issues/34 or email...
• 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,…

  Superb!...
• 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.

  Good luck!...
• Posted Memoising - standardisation of normalisation to Ed J

  Hopefully, the sesquipedalian polysyllabalisation of the title will have made your eyes glaze over. Now to wake you up: MASSIVE PERFORMANCE GAINZ!

  Memoising, as any fule…

• Posted JSON::Transform - transform JSON-able data structures without code to Ed J

  Version 0.01 of JSON::Transform is now on CPAN. It lets you express transformations of JSON-able data (i.e. data that is only hashes, arrays, simple scalars plus booleans) concisely and declaratively, without writing any other code.

  Lo…

• Posted XML::Invisible - writing parsers without pain or code to Ed J

  Version 0.03 of XML::Invisible is now on CPAN. This lets you write parsers that produce XML-like Abstract Syntax Trees (AST), or actual XML documents, without writing any code. Why did I write it?

  Parsing: a tiny introduction

• Posted SQL::Translator::Parser::OpenAPI - generate a relational database from an OpenAPI schema to Ed J

  Version 0.04 of SQL::Translator::Parser::OpenAPI has just been uploaded to CPAN. You can give it an OpenAPI 2 spec and it will generate a relational database from it. How is that useful?

  Normally when you want to make …

• 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.

  When, however, something d…

• Posted graphql-perl - plugin to make GraphQL "just work" with OpenAPI to Ed J

  The just-released v0.03 of GraphQL::Plugin::Convert::OpenAPI provides a plugin to convert a given OpenAPI specification (the spec formerly known as Swagger) to a GraphQL schema.

  There is also now a ="https://gi…

• Posted graphql-perl - plugin to make GraphQL "just work" with DBIx::Class to Ed J

  As mentioned in the LPW "trailer" for shiny new toys, I will be giving a talk on graphql-perl. I promised to talk about introspecting a DBIx::Class schema to make a GraphQL interface.…

• Posted graphql-perl - graphql-js tutorial translation to graphql-perl and Mojolicious::Plugin::GraphQL to Ed J

  Version 0.16 of GraphQL implements most of using the Schema Definition Language to create schemas, rather than doing so programmatically. So let's now translate all the idioms in the JavaScript GraphQL…

• Posted graphql-perl - Mojolicious::Plugin::GraphQL - Mojolicious GraphQL endpoint to Ed J

  Having made a Dancer 2 plugin to easily make GraphQL endpoints, it only seemed fair to make a Mojolicious plugin to do the same thing. That has just been

• Posted graphql-perl - Dancer2::Plugin::GraphQL - Dancer2 GraphQL endpoint to Ed J

  The porting of GraphQL to Perl 5 (sponsored by Perl Careers) continues. With v0.12, released 10 Oct, it is possible to run queries and return results. This includes the introspection query built in to GraphQL.

  Now there is a Dancer 2 plugin: ="htt…

• Posted graphql-perl - MooX::Thunking - Deferred computation attributes to Ed J

  As part of porting GraphQL to Perl (sponsored by Perl Careers), one of my goals is to use the best possible practice in making rigorous code. One way to use this is to imitate the style of the JavaScript reference implementation's use of immutable data…

  Great post. Love the clickbait title!...
• Posted graphql-perl - Pegex findings to Ed J

  I'm porting the reference implementation of GraphQL for JavaScript to Perl, sponsored by Perl Careers. Part of that is obviously to lex/parse GraphQL queries. I decided to try this with

  I have recently started porting the reference implementation of GraphQL for JavaScript to Perl, sponsored by Perl Careers. My key considerations:

• Posted Perl Toolchain Summit 2017 to Ed J

  I had the honour of being invited to the Perl Toolchain Summit 2017, held in Lyon. It was amazing to meet so many of my Perl heroes, and to work with them on Perl toolchain code for a concentrated few days.

  The atmosphere, food, and company were all superb, and the opportunity to brainstor…

• Commented on Classify your RT tickets on CPAN Day!
  Would it be an interesting way to engage people's competitiveness in having a separate "RT weekend", so that the score being kept is how many RT (or github, or...) tickets get marked as resolved?...
