  • Commented on Adapting PDL to a Big Data Landscape

  • Commented on Perl 5.16.0 installed
    Leon, I did -j9 for my 8 core box (can't recall if it's 4 core and hyperthreads the other 4 or is really 8 cores). I didn't turn off testing so that probably slowed things down. That 18 minutes is...
  • Posted Perl 5.16.0 installed to gizmo_mathboy

    I thought I would see how long my new 8 core box would take to compile 5.16.0.

    It took about 18 minutes 25 seconds if stat on the build log is accurate.

    So now I have the new shiny...just need to reload all the CPAN modules I use now.

  • Commented on What should be core in Perl 5.16?
    Maybe more can be done to promote Modern::Perl, perl5i and Task::Kensho? Modern::Perl is the least "invasive" in it's changes. perl5i amps it up a bit. Task::Kensho really goes all out and now is large enough to break out into separate...

  • Posted Frozen Perl 2011: Parallel::Depend: designing a little language in Perl‎ to gizmo_mathboy

    Lembark's second talk is basically about designing a little language in Perl.

    This module is a scheduler.

    When designing a language it should be easy to edit, eyeball and parse.

    It is a good idea to have line oriented and whitespace oriented tokens.

  • Sivert K commented on Adapting PDL to a Big Data Landscape

    I was in fire and flame when i found the PDL homepage. This was very interesting. I have used perl for a lot of tasks,and also combining this with numeric analysis would be great. I have however got into some problems. Installing on Fedora 17 was not without problems. F.eks PGPLOT did not work. Being a bit frustrated i installed Strawberry Perl on Windows 7 and also PDL. Hmm, also her some moduls did not install as they should f.eks Plplot did not work.

  • pm commented on Putting Perl Back on Top in the Fields of Scientific and Financial Computing

    What I would like to see are some examples that do some graph work like the following:

    1. set up axis with ranges and annotation text
    2. plot several data point array with line color choice
    3. put multiple cross hairs on the screen in both x and y dirs

    I can do this with mathplotlib with about a dozen measly lines of code

    Because of this I have been looking at using mathplotlib even though I rather do it in perl.

  • Randy Olson commented on Putting Perl Back on Top in the Fields of Scientific and Financial Computing

    I've never used Perl so I can't comment on Perl vs. Python, but you missed two critical libraries/tools that Python also brings to scientific computing:

    pandas ( offers efficient R-like DataFrames with tons of built-in capability

    IPython Notebook ( provides a web-based notebook that enables scientists to log their research in HTML-like cells; embed images, figures, videos, and external web pages; run Python/R/octave code in code cells; and do all kinds of shell commands, data manageme…

  • taiwai commented on Putting Perl Back on Top in the Fields of Scientific and Financial Computing

    I am not sure what (3) exactly mean. For (1) and (2), Perl can also be done with just few lines. For example, with Chart::Gnuplot, it would be like:

    my $chart = Chart::Gnuplot->new(
        output => "test.png",
        xlabel => "x-axis",    # annotation text
        xrange => [0, 10],     # axis range

    # About data point array 1
    my $dataSet1 = Chart::Gnuplot::DataSet->new(
    points => \@data1,
    color => "blue", # line color chosen

    # About data point array 2
