Thomas Klausner domm

Just in case you like to know, I'm currently spending my time as a father of 2 grown-up sons, Perl hacker who is not afraid to touch other tech, sort-of DJ, bicyclist, cook & taker-of-pictures - while being 40+ years old but too lazy to update my profile once a year.

I'm also head of Vienna.pm, member of the TPF Grants Commitee and the YAPC Europe Foundation and previous maintainer of the CPANTS project.

I've got stuff on CPAN, held various talks and organise the Austrian Perl Workshops and YAPC::Europe 2007.

So if you're ...

04.03.2020: Perl Intro Curriculum

If we want to attract new people to Perl conferences (and thus Perl), we must make conferences more beginner-friendly. Update: Please check out this github repo: https://github.com/Perl-Intro-Talks/Perl-Intro-Talks I've been thinking about this topic for quite some time yet, as proven by this quote from a post I published after the Perl ...
