is CPAN::WAIT dead?

    Hey, CPAN suggested that I install the CPAN::WAIT module, but the tests are failing, in part I think because "ls6.informatik.uni-dortmund.de" seems to have a bug; the bug is, it doesn't exist.

    So I'm wondering if WAIT is a dead horse, or if it would be worth bringing up a WAIT server on my Church's little dev box and hitting that. Or perhaps somebody already did that, and the CPAN::WAIT docs and tests could be updated.

    the WAIT module also fails to install under CPAN, and I"m not sure why ... could be the same problem. Or not.

    Before I burn a lot of time, I thought I should seek the wisdom of more enlightened souls.

    If I do bring up such a thing, and people so desire, I may make it public.

    Handers try to be helpful, and might even do so without a profit motive, if we can't find a way to profit, at least. (http://invisiblehand.church)

GLPK integration

    Hello nuns and monks!

    Seemingly there is no Perl module that provides an interface to the GNU Linear Programming Kit (GLPK). Actually, its usage is not that easy as there lots of functions that have to be combined in the proper way. However, the Octave project managed to design an universal interface to GLPK in a single function.

    So I thought about porting this interface to Perl and finally managed to implement it. The Octave implementation was a great help in this task as the core function that orchestrates the GLPK functions could be reused as-is. You can find my first attempt at GitHub.

    I'd be glad to hear some opinions about this module, and I have a question: What is the policy for publishing a module on CPAN into an existing namespace hierarchy? I named the module PDL::Opt::GLPK, but I'm not sure if I need some consent to publish it.

    Edit: Added GLPK link

    Greetings,

"Terminal Velocity", a better Linux terminal graphics demo

    Last week i released a simple graphics demo for the Linux terminal (Fun with terminal color).

    The low framerate and the mostly static graphics bothered me a bit. So, i , uhm did it yet again. Another demo, this time using Inline::CPP and massaged versions of tinyraytracer and tinyraycaster to provide some actual graphical content. As a matter of fact, Inline::CPP didn't work for my borrowed(*) code, and my understanding of CPP is a 20 years out of date. So i override the Inline::CPP RecDescent module to ignore my bugs. Hey, it's not production code, just a demo...

    As in the last demo, your Terminal needs to support full RGB colors and have a size of at least 270x60 in size (characters, not pixels). SDL is sort-of-optional this time; the demo will run without sound if it can't load SDL. And as said above, you'll need to install Inline::CPP as well.

    Here's the mercurial repository: https://cavac.at/public/mercurial/demos/terminalvelocity/

    And the YouTube video: https://www.youtube.com/watch?v=MWcuI2SXA-A. OBS and YT compression did munge the quality a bit, though. Probably my fault for not understanding the OBS settings...

    This scratched an itch for me, no guarantees.
    use warnings::colored; warn "warning"; # yellow system "non-existant-command"; # red say "test"; # none eval { die "caught" }; # none say $@; # none die "died"; # red
    And the implementation:
