Parrot 4.4.0 Banana Fanna Fo Ferret Released!
Its existence guarantees nothing in itself, and the catalytic or Promethean moment only occurs when one individual is prepared to cease being the passive listener to such a voice and to become instead is spokesman, or representative. But it's important to remember the many dreary years when the prospect of victory appeared quite unattainable. On every day of those years, the as if pose had to be kept up, until its cumulative effect could be felt. -- Christopher Hitchens, Letters to a Young Contrarian On behalf of the Parrot team, I'm proud to announce the 4.4.0 release of Parrot Banana Fanna Fo Ferret.

Parrot 4.0.0 Hyperstasis released!
At one extreme, it is possible to approach the subject on a high mathematical epsilon-delta level, which generally results in many undergraduate students not knowing what's going on. At the other extreme, it is possible to wave away all the subtleties until neither the student nor the teacher knows what's going on. -Stanley J.

Re: Close($file) required in Perl 6, unlike Perl 5
On Sun, Jul 17, 2011 at 4:21 AM, Moritz Lenz mor...@faui2k3.org wrote: Question to the Parrot developers: How could I implement DESTROY methods in Rakudo? Is there any vtable I can override, or so? Note that such a method might itself allocate new GCables. While not urgent, it's important for us in the long run. We do have the ability to override VTABLE_destroy in a C-based PMC type, but that is not exposed through Object PMC. I suspect this capability could be exposed through 6model and the Rakudo PMC infrastructure, and a Sub could be invoked from there. Because of the sensitive nature of the timing, and because this has obviously not gotten any good test coverage or developer attention, it probably won't work so well. This hasn't been a high-priority issue so far, either amonst users or developers. If people are interested in seeing this happen, failing use-cases or even tickets requesting fixes would be a great place to start. My suggestion so far would be to add in a destroy override to 6model, try to use it, and see what blows up. Then open a ticket with Parrot and we'll do our best to make it work the way you need. --Andrew Whitworth
Parrot 3.3.0 Fire in the Sky Released!
Nor is there any embarrassment in the fact that we're ridiculous, isn't it true? For it's actually so, we are ridiculous, light-minded, with bad habits, we're bored, we don't know how to look, how to understand, we're all like that, all, you, and I, and they! Now, you're not offended when I tell you to your face that you're ridiculous? And if so, aren't you material? You know, in my opinion it's sometimes even good to be ridiculous, if not better: we can the sooner forgive each other, the sooner humble ourselves; we can't understand everything at once, we can't start right out with perfection! To achieve perfection, one must first begin by not understanding many things! And if we understand too quickly, we may not understand well. --Fyodor Dostoevsky in The Idiot On behalf of the Parrot team, I'm proud to announce Parrot 3.3.0, also known as Fire in the Sky.

Doing one thing well is so much better for everybody then doing a million things poorly. An assorted blob of data repository is far less valuable to the Perl5, Perl6, and Parrot communities then a dedicated library repository is. Why? Ever heart of extensible meta-data. Can be done in two ways. The idea is tha, on the three levels of implementation (see recent email in other thread), you have some meta-data. I'm not saying we *can't* create a general repository for all sorts of nonsense, I'm saying that we *shouldn't*. It doesn't matter what kind of meta data you use, or how you structure your URI, or whatever: It's a bad idea. In this case, we should follow the maxim that less is more, and realize that a tighter focus will create better value. People are going to form a one-to-one association with your project and what they expect to find there. When I think email, I immediately associate that in my mind with gmail. When I think encyclopedia, I make an immediate association to wikipedia, and vice versa. What do we want people to think about when they think about CPAN, dynamic software packages or all sorts of assorted garbage with extensible metadata. The ONLY difference between a specialized implementation of an archive and a flexible one like I propose, is that in the latter you are forced to clearly assign meta-data facts to one of these three levels. But there is no limitiation in the amount and content of the meta-data you can collect. If you want to create an infrastructure that is vastly extensible and too clever by half, that's you're prerogative. I don't care what software infrastructure we use for a new CPAN, nor what methodology is used to design it. What I do care about is that the final CPAN website that we end up with only contains packages related to Perl5, Perl6, and Parrot. Create a server that can theoretically handle images and other garbage if you want to, but we should make sure the site administrators disable that feature immediately. Well, so your worries are unjustified. And the two simple solutions as I promissed in the first line of my comment: 1 Add three seperate meta-data fragments to one blob 2 Create one meta-data file which contains all three components. As simple as that. Again, we are capable of doing this from a technical standpoint. It's still a bad idea. --Andrew Whitworth

Why stop there? What is the overlap? It is basically all just some blob of data with some associated meta-data to search and retreive the blobs. It is only the client side install tool which looks into the content of the package. Why not allow pure pod releases? A small step to documents in any other format. Why not share holiday pictures? Also just a blob of data with some meta-data. Your idea of using CPAN to share holiday pictures is one of the things that really turned me off from your CPAN6 proposal. I do want this to be about Perl, you don't, and that's a point where we differ. In my examples, Nokia.bin is so that mobile users don't have to compile software on their tiny CPUs. I can see merit in adding Ruby modules because in a new Parrot world, there is real opportunity for Perl and Ruby to share libraries with each other (e.g. Perl on Rails). But when you start talking about sharing holiday pictures, you have completely left the Perl realm and I am completely turned off. I agree. Doing one thing well is so much better for everybody then doing a million things poorly. An assorted blob of data repository is far less valuable to the Perl5, Perl6, and Parrot communities then a dedicated library repository is. Adding metadata to something like the existing CPAN that describes language and implementation is a step that allows Perl6 libraries and maybe even POD-only releases (language=pod, platform=pod) to be supported in the short term and opens the possibility of multiple languages being supported in the future. However, adding these two bits of metadata cannot be used meaningfully to allow all sorts of random media, which is a Good Thing. We want a future CPAN to be the place to go for supported and tested library packages for Perl and maybe other languages, not the place where people dump assorted unrelated shit. --Andrew Whitworth
