Chris: How are you going to present & store this ? This question seems to pop up once in a while on this list.
Only 1 change: apart from mainly using 2.4.5, I also use 2.4.7 http://packages.ubuntu.com/precise/pdl I will be upgrading to Ubuntu 14.04 in 2014. As I see it now, that will be 2.4.11 at least: http://packages.ubuntu.com/trusty/pdl http://qa.debian.org/popcon.php?package=pdl All calculations on energy use of trains for the Netherlands Railroads are done in Perl/PDL: http://conference.europoint.eu/railwaysandenvironment/friday.htm sheet 13: * NS makes use of a system for feedback without the need for energy metering on the trains • Makes use of section occupation data and smart statistics • Speed profile and relative energy consumption (light version, Hoogenraad Interface Services) The predictions of number of travellers for the Netherlands Railroads are at least partially done in perl/PDL: http://www.vvs-or.nl/db/upload/documents/Journals/STAtOR/STAtOR_2010-1_totaal.pdf Why perl/PDL: * easy I/O and cleaning of contaminated data * quick to program * calculations easily distributed over a cluster * PDL (Perl Data Language) is great: the power matlab with the I/O and speed of Perl.

--- Begin Message ---Chris: Do you know who in the pd active world is the contact to Henning Glawe ? http://qa.debian.org/[email protected]#pdlProbably the best way to go is try to make a new PDL-2.4.10 debian package (including the fixed broken links) and let me have a try in using it.Jan Hoogenraad wrote:I am very happy with 2.4.5, but would be willing to give a packaged 2.4.10 a try. I do not know how to package in debian / ubuntu, but can help with testing.Note that the current LTS release has 2.4.5 and the http://packages.ubuntu.com/lucid/pdl The latest non-LTS release has 2.4.7 currently as target http://packages.ubuntu.com/oneiric/pdl Chris Marshall wrote:OK. If you are interested after PDL-2.4.10, we could take a look at a private build for PDL on your system. It is much smoother now and I would like it to build cleanly where possible. If we can give feedback to the debian packagers it might be possible that the backport could happen for PDL too....

This is not the case for PDL. chm wrote:On 1/23/2012 1:03 PM, Jan Hoogenraad wrote:As a simple user (not PDL developer), running about 4 processorsfull-time with PDL code (yes: I USE PDL), I have not used CPAN at all,not will do so in the near future.I have tried PDL from CPAN, but after it started downloading hundreds ofpackages (including half of perl, which it deemed outdated), it still did not run with my pre-compiled perl. So I gave up on that. I never use PDL plotting. For stability& configuration management, I use Ubuntu (=debian) packages. (current version: PDL v2.4.5 (supports bad values))For what it is worth, the latest stable PDL package for debian is for version 2.4.7. The current PDL-2.4.10 release candidate is testing the best of all previous PDL versions so you may wish to consider an upgrade at some point. Cheers, Chris<<attachment: jan.vcf>>

--- Begin Message ---I now see your later mails. Anyway: thanks for the link: It points out that PDL updates are waiting on a plplot update. http://release.debian.org/migration/testing.pl?package=pdl Also, I now the packages using pdl: http://release.debian.org/migration/testing.pl?waiting=pdl 1. libpdl-io-hdf5-perl (150 days old) is waiting for pdl: 2. libtfbs-perl (153 days old) is waiting for pdl: 3. libpdl-netcdf-perl (356 days old) is waiting for pdl: Ubuntu popcon for those packages: Package: libpdl-fit-levmar-perl 0 2 0 0 Package: libpdl-netcdf-perl 0 67 0 0 Package: libpdl-io-hdf5-perl 0 24 1 0 Package: libtfbs-perl 1 93 4 0They do not seem to be the reason for Ubuntu PDL installations, as suggested in the mail group.p valdes wrote:To much good to be true efectively: 67 regular users of PDL package after Ubuntu plus 84 regular users of PDL in Debian that have the popularity contest activated

Would you mind posting those numbers to the Perldl mail group ?I would appreciate if you do that, as I don't want to take credit for data I did not supply out of ignorance.p valdes wrote:And more than 115.000 people use pdl regularly in Debian...

--- Begin Message ---I don't know what other modules depend on PDL. Bioperl in lucid did not depend on PDL directly http://packages.ubuntu.com/lucid/science/bioperl Anyway: the numbers are lower: Package: bioperl 107 2117 15 1 Package: bioperl-run 11 989 21 0 Apparently, for developers there is a command: reverse-build-depends https://wiki.ubuntu.com/UbuntuDevTools I don't have sufficient source packages to run it on pdl. David Mertens wrote:Thanks! That's an astounding number, but I think it's probably an overestimate. For example, I suspect that many of those people are through dependencies rather than direct usage. I know that some BioPerl modules depend on PDL. But, at least we know that thousands of people use PDL, whether directly or indirectly. That's pretty cool!
