• Posted pperl 0.6.21 - addendum to PetaMem

  This blog entry has no release attached to it. 0.6.21 is an internal happened, but this post is not about new things. It is about old things the 0.6.20 post forgot, about how a project moving at this pace should announce anything…

• Commented on pperl 0.6.20 - The Player of Games
  Yes, so did I. But one has to admit, that the "optimized Perl" that eventually got accepted - like putting everything into an eval - was more a hack rather than optimization. The interpreter is simply at its limits. The...
• Commented on pperl 0.6.20 - The Player of Games
  Yes, the vast majority of coding, testing, documentation is done with AI. The human part that remains is direction (what has to be done) and evaluation (is that what has been done ok). The project started December, 27th 2025 -...

• Posted pperl 0.6.12+ - "Shall we play a game?" to PetaMem

  There is no release attached to this post - the second half will posts claimed that pperl is under high-velocity development, and a claim like that should be quantified - so we do, with the same statistics perl's own release notes us…

• Commented on Moving Targets - PetaPerl 0.6.8
  Going open source is not planned and "being more open" is what I try to do here. That being said, I think open source does a few jobs under one name (much like XS) and I believe some of them...
• Commented on Moving Targets - PetaPerl 0.6.8
  Yes, the docs do lag somewhat behind. Rebuilding the current docs in 42 locales takes about 2 hours on a 32-core machine and the cadence of the releases... Like right now the docs are @0.6.8/5.44 but the binary is already...
• Posted Moving Targets - PetaPerl 0.6.8 to PetaMem

  Two weeks ago we announced PetaPerl 0.6.0. Today, 0.6.8 goes meaning, but if you insist, you can call this the "дурак Go Home" edition. The headlines: pperl has now perl 5.44 as compatibi…

• Commented on "I had a dream" - Announcing PetaPerl 0.6.0
  So breaking news: Readers of the 0.6.0 announcement will remember its caveat: the bare interpreter, JIT off, ran about 30% behind perl5. That caveat did not survive 0.6.1. The interpreter alone - JIT and parallelizer disabled - now runs the...
• Commented on "I had a dream" - Announcing PetaPerl 0.6.0
  Good question, for which I do not have a thorough answer right now. We seriously did focus on Perl, but it seems all people are interested in is C and XS. :-) Maybe I should do a separate writeup on...

• Posted The Perl Documentation - Rewritten to PetaMem

  Well, not all of it ... yet. But some of it has been rewritten many times in many languages and "all" of it will be rewritten in many more languages. Of course "all" will never be reached, so it will be an ongoing endeavor, but at least you know the goalposts.

  You can read it at …

• Commented on AI as a Chance - Opinion
  I disagree with your notion of LLMs being "probabilistic models". You may confuse LLMs with SNLP. LLMs can be configured to produce deterministic output, but effectively this never happens and there is no value in making that happen. If you...
• Posted AI as a Chance - Opinion to PetaMem

  Use AI. Use it more and better. If you are not yet equipped to use it those in the community who are.

  That is the whole argument. The rest of this piece is why I think it is correct, and why I think the current register o…

  I will not, and they are not humanoid in any sense. Thank you for your opinion.

• Brett Estrade commented on "I had a dream" - Announcing PetaPerl 0.6.0

  With all the AI being used to improve core now (rewrite of the XS system in 5.44), it might be time to tackle adding thread safe versions of data structure data structure access and modification functions (HV, AV).

• Ed commented on Moving Targets - PetaPerl 0.6.8

  I wish you'd consider moving development to GitHub and being more open. I hope that's in the cards someday.

  Congratulations on the DBI and DBD stuff. That's awesome. I have to say that was the biggest reason why I hadn't tried pperl. Probably 80% of my Perl code accesses a database.

  As a collaborator on the DBD::Pg project, I am wondering how you got DBD::Pg working. I presume you are testing your implementation with the DBD::Pg tests? Are you going to be tracking new releases of DBI and DBD::Pg (etc.) going forward? We have a new release with new features/capabilities in the…

• Dana Jacobsen commented on pperl 0.6.20 - The Player of Games

  Years ago I and various others tried to get the benchmark games Perl code replaced with faster versions that still followed their rules. They never accepted any changes. It was frustrating seeing ancient unoptimized Perl code being used for those benchmarks.

• Dana Jacobsen commented on pperl 0.6.20 - The Player of Games

  Oh I agree, 1.5-3x from using proper code rather than whatever hack they were using is not enough. At least it wouldn't make Perl look so bad vs other interpreted languages, when often it was just bad code.
  Recently someone on Quora posted a language comparison, without code included, and the Perl is ludicrously slow, as in 500x slower than using the simple RosettaCode for the task verbatim. I mean I know Perl isn't fast vs C, but it isn't nearly as slow as some of these comparisons make it seem.
  

  
  Yes, pperl is a good direction, as otherwise we too often end …
