I’m working on one Moose-based project and ran into bad difficulties yesterday. Suspicious compile time errors, default value subroutines being called way too early and with an empty hash reference as argument instead of an object. It took me hours and some hints from #moose on irc.perl.org to find a workaround and finally today, I was able to reproduce the problem. (weiterlesen …)
I don’t like Moose. It has a lot of disadvantages and tries to create a new language based on Perl – without any need.

How to concat an array into a string? Perl is TIMTOWTDI and I could imagine two common ways – but which one is the best? (weiterlesen …)

.Sybase ASE is one of my preferred databases and the Express Edition is freeware (thanks, Sybase!) but using the OpenClient driver on a plain German Linux installation issues some error messages: (weiterlesen …)
I recently started my first Dancer & MongoDB project. MongoDB is my preferred database (at the moment) and Dancer is a great framework, but something is missing: I really prefer using an ORM and didn’t find anything for MongoDB which fits my needs. (weiterlesen …)
Did you find a typo in the title? No? You’re right. I recently started to love the Perl Dancer Framework – and tried to write my first cronjob for a Dancer based project today. (weiterlesen …)
