Raku NativeCalls provide a way to interact with dynamic libraries that follow the C calling convention and are very useful for obtaining information from the operating system, such as memory usage.
In this article we will see how to get the memory usage from a Windows system.
Win32 API provides the MEMORYSTATUSEX structure:
This is designed to be a working proposal. Comments/corrections/suggestions are welcome, as the first draft was written fairly hastily. I'm working on doing a rough implementation to play around with, beginning with the Binex proposal, which can be found here. It is not currently a full implementation of this proposal, but progressing rapidly.
Grammars in Raku are awesome, and allow for some truly amazing text parsing.
Unfortunately, they are less than ideal for binary files,
and there is no way to have them support matching objects, both of which would be very useful (image being able to pattern match on an AST!)
This requires writing complex and/or error prone workaround code.
El sistema donde se ha probado lo aquñi descrito es Debian stable (10.3)

Sad news. Our dear friend Jeff Goff has died in a scuba diving accident. He told me and many others about how he looked forward to learning more about scuba diving, getting more experienced in it, during the JoCo Cruise ( https://jococruise2020.sched.com/jeff_goff.1zitf4ff ). Apparantly, something went horribly wrong.
I have spent many hours with Jeff, not in the least when he broke his hip in Spain during the Perl conference in Granada, and I took it upon me to take care of several things for him. He has stayed as a guest at least twice in my home. I have learned to know Jeff as a warm, loving man, with a great sense of humor, wonderful ideas, and always helpful. Last time I saw him when he took over from me at the Perl & Raku booth at FOSDEM in Brussels.
Needless to say, but it needs to be said anyway: Liz and I will miss him terribly. The Perl & Raku communities will miss him dearly, as he was one volunteer who has done a lot of things to make things happen, to make things better.
