Slides for my Talk "Perl on MVS and the Art of Parsing and Generating SWIFT Messages" to be held at this year's YAPC 2006.
During the YAPC 2006 Marty had a talk about "Lithp" where we (Marty and I) got a bit of an argument about LISP and APL, so I decided to prepare a lightning talk during the night. On the next day I learned that one speaker did not show up so there was a regular slot available for a real talk, thus I expanded my slides a bit and delivered a talk APL - one of the coolest programming languages ever ...inspired by the 'Lithp' talk.... Enjoy...
Since we (Rikka and I) were invited to a new year's party which required all of the participants to give talks about paranormal phenomena and the like, I decided to talk about the random number generator experiment which was conducted in 1998. The slides for this talk can be found here.
Last year (2006) I started the design and development of yet another homebrew processor, a simple but elegant 16 bit architecture called QNICE. A slide set describing the machine can be found here.
At the IT Symposium 2007 I will deliver a talk covering database proxies written in Perl. The slides for this talk can be found here.
At this years Vintage Computer Festival Europe I will deliver a talk about one of my favourite programming languages, APL, and about one of my favourite programmable pocket calculators, the TI-59 - the slides for this talk can be found here.
Yesterday (06-FEB-2008) I gave a little talk at the University of Hamburg with the title "Faszination Analogrechnen". The slides for this talk are available for download here (ca. 2.9 MB).
On June, the 5th, 2008, I held a talk about Thomas Samuel Kuhn's seminal book "Die Struktur Wissenschaftlicher Revolutionen" at the Johannes Gutenberg University, Mainz. You may find the accompanying slide set here.
On the very same day, June, the 5th, 2008, I also had a talk about Perl and OpenVMS at this year's DECUS symposium which took place in Frankfurt. The slides which give quite some examples of the practical use of Perl in an OpenVMS shop may be found here.
