  • Commented on Ideas for perl.org.in | an Indian connecting platform
    I think any sort of community building is a wonderful effort, to be commended. Solving a low-density issue is a hard problem, and the internet-based solutions you suggest sound like good ones. I can think of two basic issues you...
  • Commented on playing with Cairo
    Hey Dmitry, Could this be sped up using PDL? As I'm sure you know, I would be *very* happy to have a Cairo-backed PDL::Graphics::Prima, so anything I can do to move this along I'll do. :-) Context for those unfamiliar:...
  • Posted DOIs for Perl Module tarballs, probably to David Mertens

    A while back, Mark Fisher wrote about DOIs. As an academic, I asked about how I might cite a DOI for some Perl work. I was recently made aware of two possibilities.

  • Posted Lexical closures with END blocks warn, but Just Work to David Mertens

    I was just impressed by the awesomeness of Perl. More testing revealed to me that "use 5.018" does not invoke "use warnings", which dampened my enthusiasm a little. But Perl is still pretty awesome. Here's the situation.

    I write lots of Prima GUI applications. In this one (a presentation i…

  • Commented on Perl and Me, Part 6: Perl Is Engineering <i>and</i> Art
    The first part of your post is beautiful! Thank you! The second, more rant-ish part of your post, is what I would say if I were as good a write as you: I have not one but two unpublished drafts...
  • Commented on On Readability
    brian - I happen to agree with you, which is why I think that the two languages are equivalent. I usually hear this argument coming from the Python folks, not the Perl folks....
  • Commented on What?! CUDA::Minimal... works?
    Well, the general rule is that CUDA in a virtual environment doesn't work because the virtual environment doesn't have direct access to the video hardware. Your best bet is to install Linux on the machine directly and install the necessary...
  • Commented on how I learned to plot a mandelbrot set
    @Dmitry - I have been thinking about this a bit lately. I suppose here is as good a forum as any for discussing some of my ideas. One idea I have is to revise PDL::PrimaImage so that Prima and PDL...
  • Posted What?! CUDA::Minimal... works? to David Mertens

    I wrote CUDA::Minimal back in late 2010/early 2011 and used it in some of my research before defending my Ph. D. dissertation in May of 2011. At my postdoc I didn't use parallel anything, so CUDA::Minimal languished. When I picked it…

  • Commented on how I learned to plot a mandelbrot set
    Dmitry, very nice! By the way, the first time I ever heard of Prima was because I once looked up other modules that used PDL. PDL::PrimaImage was one of the few, and I was happy to see it. So it's...

    Hello, Makoto. :-)...
  • Commented on Introducing Fetchware: package management for source code distributions.
    Very cool!...
  • Commented on OT: DataCite Recommends "doi:" Scheme Prefix
    Mark - I've been thinking lately about citing my Perl work in journal articles, specifically via a doi. Do you know if there is any doi provider for Perl modules? I strongly suspect not, but figured I'd check with somebody...
  • Commented on Using Stratopan Beta
    Wow. Wow. Thanks for showing this off! $Jeff += like, a million....
  • Commented on PDL::Graphics::PLplot become to be able to output png format in Windows Active Perl ppm
    Yuki - Thanks for posting the install instructions for Windows. I don't use Windows, but I know that PLplot can give trouble when it comes to installing it on Windows. Having the instructions publicly available is a great help....
  • Commented on PDL installation to Windows fail.
    Yuki - Chris Marshall, the current PDL release manager, is far and away the best resource for issues with PDL on Windows. It is best to send mail to the mailing list. To do that, you have to subscribe because...
  • Commented on (my) Marpa Best Practices
    Man, Marpa looks like such an awesome tool. It makes me wish I had a parsing problem to solve. And some day, when I do, I'll check it out. :-)...
  • Commented on List shortage of Perl
    @Code Monkey, thanks for the kind words. @Yuki, thanks for the apology. You are expressing a wish that Perl was used more for numerical work and I share that wish. I think the issue was that I misread your wish...
  • Commented on I try to use PDL::Stats, but Test failed.
    PDL just released a new version that is not binary compatible with older PDLs. I suspect that Maggie hasn't uploaded the latest outside of a dev release. I also need to update PDL::Drawing::Prima for the new version of PDL. Does...
  • Commented on List shortage of Perl
    Yuki - I cannot speak directly to your first three concerns, but I can speak to the last one. I have worked extremely hard over the last five years to make PDL better. When I started using PDL, I felt...
  • Commented on Backing up private data securely
    Check out BitTorrent Sync. I used to keep my work and home projects synchronized with git, but I found that I kept pushing incomplete work to my repo just so I could work on it at home. If you keep...
  • Commented on I want mop rest capability to define fast accessor
    Yuki - You really should look into XSAccessor. If you like it, you should push its use. It is *faster* than direct hash access due to crazy op tree fiddling. Seriously, check it out. As for what you want, what...
  • Commented on PDL 2.007 Released!
    Hurray! Thanks Joel for posting this! 64-bit support FTW! chm++ @Yuki - Yes, when most people have a problem to solve for which PDL would be well suited, they think of Matlab, numpy, R, or XS/C. Why not PDL? I’m...
  • Commented on Am I pandering to the smoke testers?
    @Jeffrey - Actually, I *can* run the compiled tcc executable. The test suite invokes a great many C test programs through tcc, which is a binary built by the distribution itself, so it looks like Nigel's setup does indeed allow...
  • Posted Am I pandering to the smoke testers? to David Mertens

    I have a quick sanity check I'd like to throw out there.

    I've been working all week on Alien::TinyCC, and I made some great progress. My initial distribution wasn't properly checking that the build steps completed successfully, so I w…

  • Commented on C::TinyCompiler, a just-in-time C compiler for Perl
    Ahmad, Sorry it took a few iterations to get that right. I released Alien::TinyCC v0.03 to cpan last night (after six developer releases) and it has a 100% pass rate at the moment, including on Linux, Mac, Windows, and FreeBSD....

    Heh, why don't we refer to the systems as "stiff typing" and "spongy typing"? :-)...
  • Posted XS::TCC, another tinycc-based jit compiler to David Mertens

    Without knowing it, both Steffen Mueller and I released modules this morning related to using the Tiny C Compiler for compiling C code at runtime! I have tried to make a fuss about mine (as evidenced by

  • Posted C::TinyCompiler, a just-in-time C compiler for Perl to David Mertens

    There are many things you might do to speed up your Perl code. After profiling and benchmarking, you revise the slow spots, or maybe try a different algorithm. If you still need more speed, you may use Inline::C, or use PDL if you are doing numerics, or even write your own XS code. Reini Urban…

  • Commented on Come see me at YAPC::Brazil!
    Aghh!! I totally want to attend this! Alas, I shall be in the middle of my first semester of teaching as a bona-fide professor. Is there any chance the talks will be on livestreaming?...

  • Dmitry Karasik commented on playing with Cairo

    Oh, I wish! I don't know PDL well enough, so to my limited knowledge there's no such thing in PDL that would do the trick.

    OTOH with Prima::Cairo you actually can make PDL::G::P cairo-based. The module is 1.00 and has only very basic stuff, but that surely can be expanded.

  • Vikas Kumar commented on playing with Cairo

    PDL::Graphics::Cairo would be awesome David !! Please do it.

  • Dmitry Karasik commented on playing with Cairo

    Raini thanks for the tip .. Indeed Inline::C speeds it up to 10 times! Now in 1.01 version :)

  • Abhishek Jain commented on Ideas for perl.org.in | an Indian connecting platform

    I like the idea of a mailing list, may be coupled with a wiki of profile of users.

    If so which wiki software should i use if not create one?

    I will be back with the mailing email but what wiki should i use.

    thanks

  • animatedream commented on Perl and Me, Part 6: Perl Is Engineering <i>and</i> Art

    First, I would never argue that python makes it hard to write bad code. It's very easy to write bad code in any language. I would argue instead that python attempts to make it easier to write good code, by reducing the number of idiosyncrasies a programmer must be informed of to make

    I don't understand the benefit to software development in being able to express a meaning in any way but the best way. I don't think the arguments put forth here really contradict that. The problem: Who's best way?

    In python's philosophy, the principle of least astonishment ranks higher than eve…
