DESCRIPTION:Melian is a tiny C-based cache server that doesn't pretend to b
 e a distributed system\, a graph database\, or the next big data miracle f
 ad. It just serves database tables at ridiculous speed and does it obnoxio
 usly well. We're talking sub-millisecond lookups\, atomic dataset swaps\, 
 and zero-copy I/O. Think "materialized view meets caffeine overdose."\n\nI
 t's read-only\, automatically refreshes from MySQL/MariaDB\, and was built
  for people who want instant lookups\, not instant consistency. Perfect fo
 r reference data\, routing tables\, metadata\, or anything that changes oc
 casionally but gets read constantly.\n\nOh\, and it has a Perl client\, al
 ong with C\, Python\, Javascript\, and PHP clients.\n\nThe talk will cover
  the data sets in which Melian shines (and where it doesn't) and how to us
 e it - including under Kubernetes\, if that's your poison.\n\nTime permitt
 ing\, we could go into over-slides and talk about the gory details of how 
 to create a cache that beats even Redis by miles and kilometers\, if used 
 correctly.

DESCRIPTION:This session will explore how modern Perl frameworks like Moo\,
  Object::Pad and experimental class feature alongwith Class::Mite (blessed
  class prototype) simplify the implementation of classic design patterns. 
 We'll move beyond traditional bless-based OOP to demonstrate cleaner\, mor
 e robust ways to build objects and apply patterns such as Singleton. Throu
 gh practical code examples\, you'll learn how to write more maintainable a
 nd scalable Perl applications using contemporary tools and techniques.

DESCRIPTION:**This time it's personal.**\n\nIn August 2007\, Matt Trout and
  I spent two days discussing Yet Another Attempt to Rewrite Perl—both the 
 language and its runtime. One idea stood out from everything else and lodg
 ed itself firmly in both our minds.\n\nAfter Matt's passing earlier this y
 ear\, I dug through old IRC logs to find that conversation and revisit tho
 se ideas. What I discovered surprised me: Matt had already started buildin
 g it.\n\nThis talk explores the crazy theories\, early prototypes\, and wi
 ld ideas Matt left behind—and how they could become the foundation for a f
 uture Perl.

DESCRIPTION:Abstract — PAGI (Perl ASGI) Project\n\nThe PAGI project aims to
  bring modern asynchronous web application capabilities to the Perl ecosys
 tem by implementing an ASGI-inspired interface that allows Perl applicatio
 ns to handle HTTP and lifespan events using async/await semantics. Modeled
  after Python’s ASGI\, PAGI establishes a language-agnostic gateway layer 
 between web servers and application logic\, enabling high-performance requ
 est handling\, graceful startup/shutdown workflows\, and future scalabilit
 y toward real-time and streaming protocols.\n\nUnlike traditional Perl web
  frameworks—which operate in a synchronous\, PSGI-style request/response l
 ifecycle—PAGI introduces structured concurrency for IO\, allowing workload
 s to be offloaded efficiently or parallelized using async pipelines\, work
 er pools\, or hybrid designs\, without abandoning Perl’s synchronous DBI c
 ompatibility or legacy integration requirements. The project addresses cha
 llenges inherent in modern web workloads\, such as WebSocket handling\, se
 rvice startup signaling\, long-lived connections\, and system orchestratio
 ns\, while remaining backwards compatible with existing Perl infrastructur
 e.\n\nBy providing a clean abstraction around application lifecycle\, even
 t loops\, and shared state propagation\, PAGI positions Perl for modern co
 mpute environments including containerized deployments\, edge systems\, an
 d MCP-driven AI service orchestration. The result is a forward-looking arc
 hitecture that retains Perl’s strengths in reliability and performance on 
 synchronous workloads while opening the door to next-generation async serv
 ices\, including low-latency chat systems\, high-throughput API gateways\,
  and AI middleware integrations.

DESCRIPTION:Nearly all programming languages ever developed use a subset of
  English for their keywords. Educated people in the future will be literat
 e (able to read and write)\, numerate (able to calculate and use numbers)\
 , and coderate (able to interface with computers). But if the computer lan
 guages available require knowledge of a subset of English\, then most of t
 he population of the world will have a barrier to being coderate at an ear
 ly age.\n\nThe Raku's new Abstract Syntax Tree compiler separates the huma
 n-readable portion of the language from the machine compilable portion. It
  is therefore possible to write a computer language that uses any human la
 nguage for its keywords. Moreover\, a program written in (for example) a J
 apanese version of Raku can be mapped onto the English version\, shared wi
 th  a developer to help debug and mapped back to the Japanese.\n\nIn the t
 alk\, I will demonstrate how to create a new language\, discuss the advant
 ages for human society\, and thus illustrate the advantage of a universal 
 auxiliary language for interaction.
