Stackato is a cloud solution from renowned ActiveState. It is based on the Open Source CloudFoundry and offers a serious cloud solution for Perl programmers, but also supports Python, Ruby, Node.js, PHP, Clojure and Java.

Stackato is very strong in the private PaaS area, but do also support as public PaaS and deployment onto Amazon’s EC2.

The presentation will cover basic use of Stackato and the reason for using a PaaS, public as private. Stackato can also be used as a micro-cloud for developers supporting vSphere, VMware Fusion, Parallels and VirtualBox.

Stackato is currently in public beta, but it is already quite impressive in both features and tools. Stackato is not Open Source, but CloudFoundry is and Stackato offers a magnificent platform for deployment of Open Source projects, sites and services.

ActiveState has committed to keeping the micro-cloud solution free so it offers an exciting capability and extension to the developers toolbox and toolchain.

More information will follow and the presentation will be made available online when it becomes available.

The workshop will held on the first and second of May 2010 and will be organized by a local group, FSFI, which is the Icelandic Society for Digital Freedoms.

The official website in its current form is located at: a href=”http://npw2010.fsfi.is/”>http://npw2010.fsfi.is//a>. A preliminary call for papers is out via this site – more information is expected to follow.

For a more thorough description of the FSFI, please visit: a href=”http://www.fsfi.is/”>http://www.fsfi.is//a> (in Icelandic)

In it unclear whether logicLAB will be represented at the NPW 2010 at this time, please keep an eye on this space for more information.

It has finally been release to the CPAN.

The distribution by now contains 3 modules, representing 3 different approaches to validation of Danish phone numbers.

- Business::DK::Phonenumber, is a basic procedural implementation, exporting a validation subroutine.
- Data::FormValidator::Constraints::Business::DK::Phonenumber, is a package to integrate with the marvellous module Data::FormValidator
- Class::Business::DK::Phonenumber, is a object oriented implementation providing a class for handling phonenumber object

In addition to the 3 approaches listed above. The distribution offers:

- Generation of dummy phone numbers, which can be used for testing
- Pretty printing of phone numbers, so phone numbers, can be output and formatted using simple templates

This is the initial public release and it covers pretty much what we expect and set out too solve, ideas for improvements are more than welcome.

Business::DK::Phonenumber is the second open source project from logicLAB, which is developed on our Atlassian Jira Studio solution, so things might change overtime as we get more into using Jira Studio for both closed and open source projects, for now the following resources are available from our Business::DK::Phonenumber project web site (a href=”http://logicLAB.jira.com/browse/BDKPHN”>http://logicLAB.jira.com/browse/BDKPHN/a>):

- Wiki
- SCM, Subversion, readonly
- Bug/Issue tracking, requires account for now, but we are working on that

Business::DK::Phonenumber is distributed under the Artistic License and can be downloaded from your local CPAN mirror or via: search.cpan.org (a href=”http://search.cpan.org/~jonasbn/Business-DK-Phonenumber”>http://search.cpan.org/~jonasbn/Business-DK-Phonenumber/a>).

The tool implemented in Perl takes the existing exports and does manipulation and filtering on them for finer control and application of certain business rules to improve and optimize the output.

The tools have grown over the years and in the spring of 2009 a lot of new feeds were added to the existing suite of tools. This indicated a long awaited refactoring of the code base, which had grown organically with the requirements from Itzy-Bitzy Communications and LOGU.

One of the things that came out of that refactoring was WWW::DanDomain a class based on Andy Lesters marvellous WWW::Mechanize (http://search.cpan.org/~petdance/WWW-Mechanize/lib/WWW/Mechanize.pm) a Perl module, assisting the developer in creating an HTTP client for accessing and retrieving data via HTTP.

WWW::DanDomain is for now pretty slim, but it is the core foundation in the tools created for accessing DanDomain web based administrative interface.

The idea behind the class, it to sub-class it and overwrite the processor method, which is the place to hook in, in order to get access to the product export data.

Currently we have implementations doing the following:

- Converting to XML from CSV
- Merging of data from two different exports
- Conversion from ISO-8859-1 to UTF-8
- Complex business rules changed single fields in export
- Creation of exports for service providers not supported by DanDomain (see the list above)
- Cleaning of exported data

WWW::DanDomain is the first open source project from logicLAB, which is developed on our Atlassian Jira Studio solution, so things might change overtime as we get more into using Jira Studio for both closed and open source projects, for now the following resources are available from our WWW::DanDomain project web site (http://logicLAB.jira.com/browse/DAND):

- SCM, Subversion, readonly
- Bug/Issue tracking, requires account for now, but we are working on that

WWW::DanDomain is distributed under the Artistic License and can be downloaded from your local CPAN mirror or via: search.cpan.org (http://search.cpan.org/~jonasbn/WWW-DanDomain/).

The conference it the annual european Perl grass-roots conference and we are happy to be able to support this event. The next thing to find out is whether we will be to attend.
