All about Perl 6 – interview of Jonathan Worthington (Part 3 of 3)

 NV: The JVM has been primarily designed with statically typed languages in mind. The same goes for the CLR, and that is why the DLR (build on top of CLR) came into existence.  Have you at some point considered the DLR (maybe combined with Mono instead of the CLR) or JVM’s Dynalink, both of which admittedly have a good Meta Object protocol infrastructure, as a potential backend to Rakudo?
JW: One interesting thing to note about Perl 6 is that it’s  a gradually typed language, which means the considerations are a little different from if it was dynamically typed. In that sense, VMs which explicitly seek to do both static and dynamic typing well are especially interesting for Perl 6.
I can’t speak too well to the DLR, but I do know that Niecza, the Perl 6 on CLR implementation, went the way of not using it for a range of reasons. By contrast, the JVM’s invokedynamic instruction has been rather interesting from a Perl 6 implementation point of view.
Dynalink is certainly of interest too, in so far as it seems to provide an interesting path to enabling calling Perl 6 code from Java. I’d rather reuse an existing solution than reinvent that wheel. I need to dig into it more deeply to be really sure.

Book Review : How To Create Pragmatic, Lightweight Languages

At last, a guide that makes creating a language with its associated baggage of lexers, parsers and compilers, accessible to mere mortals, rather to a group of a few hardcore eclectics as it stood until now.

The first thing that catches the eye, is the subtitle:

The unix philosophy applied to language design, for GPLs and DSLs"
What is meant by "unix philosophy" ?. It's taking simple, high quality components and combining them together in smart ways to obtain a complex result; the exact approach the book adopts.
I'm getting ahead here, but a first sample of this philosophy becomes apparent at the beginnings of Chapter 5 where the Parser treats and calls the Lexer like  unix's pipes as in lexer|parser. Until the end of the book, this pipeline is going to become larger, like a chain, due to the amount of components that end up interacting together.

The book opens by putting things into perspective in Chapter 1: Motivation: why do you want to build lan…

Deep Angel-The AI of Future Media Manipulation

Undeniably, we live in the era of media manipulation. Such powerful and accessible tools exist today that nearly everyone can do it. Now add to this collection Deep Angel, an artificial intelligence that can erase objects from photographs and videos.

I was notified of Deep Angel around the time I was watching Kill Switch, a futuristic and dystopic movie about our Earth getting cloned in order to suck the resources of the cloned planet, something that would sustain our world's energy needs for at least another millennium. To cut a long story short... full article on

SAP's Creating Trustworthy and Ethical Artificial Intelligence

With the ink hardly dry on the pages of the EU Ethical AI Guidelines manifest, a free online course exploring the issues they raise is already in prospect on the openSAP platform. Run by members of the very same group, the European Union’s High-Level Expert Group on Artificial Intelligence, who wrote the guidelines and in cooperation with SAP's online education platform, a course with the titleCreating Trustworthy and Ethical Artificial Intelligence has been made accessible to anyone with an interest on AI or ML:
