Re: Yet another Lisp related screencast

This basically defines a new setf expander. You might want to look up defun, defsetf and the like in the CL HyperSpec for a more detailed unterstanding. However, in the case of the matrix it allows an aref-like access of the matrices elements both for reading and writing.

Yet another Lisp related screencast

Hi there, because I liked the excellent Lisp screencasts of Marco Baringer and Rainer Joswig and due to the lack of additional freely available stuff like the beforementioned, I've thought about creating comprehensive tutorial-like screencasts myself. So, during the past summer I began with the crea...

Re: SBCL 1.0.19 released

Just head over to the SF download section via the link that's provided on sbcl's homepage. The same "problem" happened to me not too long ago ;)

Re: CLOS usage

Thanks Geoff. As I totally agree with what you've written, IMO the "problem" was just due to my misusage of the term "method". The origin of "my" part of the discussion was where I stated that I preferred "functions" over "methods" wherever possible. My sole intention with that was to mention the ex...

Re: CLOS usage

Please correct me if I'm wrong, but I thought that the major difference between "functions" and "methods" -- with respect to Lisp and/or CLOS -- was that for methods, CLOS first looks up the most suitable (specialized) version of a method in regard to the given parameters, whereas this need not be ...

Re: CLOS usage

Hm, I like CLOS and fairly often use objects. However, I prefer using "regular" functions instead of methods wherever methods aren't explicitly neccessary. In CLOS, you are still using functions. The best way to think about CLOS is that what you're writing is generic functions. (This is clearer if ...

Re: Strings, characters, and binary encodings

Maybe this was a misunderstanding. Of course I see your point, however I'd not like READ-BYTE to behave in a way other than reading a byte from a given stream (because that's what I think it is supposed to do). Instead I'd prefer another standard solution for the mentioned problem. This way or that ...
