Things I can or have done



Fortunatly I had the chance to learn a few other programmers, while running Q Software Solutions GmbH. It should be clear that I learned from them things they know better than me, e.g Jacob Navia is surely much better in the C and Windows area, but my broad interests have their advantages too ;-), although learning them has took quite some of my "working time".

Software I once wrote


I have been an enthusiastic Eiffel programmer. And even today I think Eiffel did a lot of things right which others are now still getting.

I wrote a few packages which now just have some historical value, but I think they are still not the worst pieces of programs. Feel free to judge yourself.

Eiffel Metric System
File/Directory Handling Was one of the first portable implementation to the time as at least 4 Eiffel compilers were available.
Eiffel Formatter Library To my knowledge the first port taken from SIGs now ObjectTools Formatter library which allowed formatted output for all the Eiffel compilers. Now taken over by Berend de Boer
Bignums Library. Probably even today one of the most portable. It has run under ISE Eiffel, Halstenbach Eiffel, Visual Eiffel and SmallEiffel.

My writings



I'm afraid I'm not a really talented writer, but it seem my articles are 'interesting' enough to be published. Over the years I wrote in diverse magazines e.g Toolbox, Linux Magazin and it's english counterpart, freeX

Maybe you're interested in a few of my writing, but be prepared you better beeing able to read german.

Many of the links will not work any more: What you can see currently, can be found here:

The english translations can be found in the Linux Magazine e.g

Scheme introduction
functional Scheme
Scripting with Scheme
(X)Emacs Stuff
Gnus

Of course I wrote few lines of emacs lisp over the time, those are in no way polished, the just work as they should for me ;-).
Smalltalk

Another wonderful language, way to much understimated. Large influence on quite a few languages, e.g Ruby or Self. Well where would we spend today if all the money would have given to improve Smalltalk instead of reinventing parts of it in other languages? To learn about this wonderful language you may like to check Smalltalk.

I'm not able to give you some more links. If you find some stuff somewhere feel free to drop me a note about where one can find it. I may add it here.
Lcc-win32 extras


Of course you'll find some of my work in the newest versions, but not all the things are done there and explained as properly as one may wish. This are extra packages or documentation, which are unpolished but may give some more insight into C programming with lcc-win32.
