• Posted The Secret XS Diaries to Renormalist

  I just rediscovered an old project of myself when I was learning Perl/XS and wanted to drop a hint to it here.

  It might be useful for others who also have no idea how XS works and who would benefit from the approach and point of view of another XS newbie.

  It is both the step-by-st…

• Posted Perl QA Hackathon 2015 to Renormalist

  Last post - the post that hurts the most.

  It's been a while that I blogged. Yet, it's a tradition now to write my report about the Perl QA hackathon as probably the last one of the attendees. The 2015 edition of the Perl QA hackathon was a lot of fun. I'm one of the less visible guys there…

  Some answers in reverse order: The first rule of the benchmark club: you do not change the environment of the benchmark. In other words: my changes during the hackathon could have influenced the measurements. I don't think they did, but...

  First post, the post that hurts the most. Well ... not ... but still in time before the y2k12-maya-bug triggers.

  I am late in writing this summary about my hackathon but it fits the prolongation style I exercised this time. I had quite a slow start as I found it difficult to flush my overf…

  Short summary before the day closes:

• JJ Merelo commented on 6lang: The Naming Discussion Update

  Could be x-lang (eks-lang). Not so bad, not taken as far as I know.

• Mohawk commented on Enter the Matrix ... with PDL

  Superb!

• Mohawk 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)

• Mohawk 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.
