confirmed ‎CSV with flexible headers (perl5 & perl6)‎ 30 minutes
confirmed ‎Using mixed CSV headers in DBI‎ Lightning talk


I am an analyst/programmer since 1988 working for PROCURA B.V. in Heerhugowaard, The Netherlands, which has been very openminded to OpenSource.

I am specialized in data-analysis and -conversion, mainly with databases and data-connections as focus area.

Many know me for my work on the CSV data format with Perl. I wrote a fast, versatile and flexible CSV parser for Perl 5 and ported that to Perl 6.

In my daily work, I mainly use the Perl, C, and Java programming languages. My desktop is Linux (OpenSUSE with Plasma 5) on my workstations and my laptop. Next to Linux my daily work is also concentrated on commercial OS's like HP-UX.

On the internet I am widely known as "Tux".
