Thanks Anthony! I've run through the various places I noticed this problem and they all work now.

Re: Help for Christopher Alexander in S.E. England

When computer people talk about design patterns of software engineering, they are using a term coined by this Christopher Alexander. The term architect, as applied to our field, was similarly coined by him. He appeared at OOPSLA as a guest speaker. In short, the man has exciting ideas.

Hi richard Another way would be for him to come at ESUG a friendly and small conference this year organized in Slovenia (3 hours from venice:) and meet all kind of smalltalkers and squeakers. Because there I'm sure that in a week he could get a ***lot***, even have his simulation. This is the last week of august in a beautiful country. http://www.esug.org/ Else http://www.iam.unibe.ch/~ducasse/WebPages/SmalltalkSqueak.html There are columns, Squeak quick ref for my next book and all kind of stuff. and http://www.iam.unibe.ch/~ducasse/WebPages/FreeBooks.html for free online books Stef On Thursday, July 31, 2003, at 08:31 PM, Richard Pawson wrote: > > Christopher Alexander, author of 'A Pattern Language', wants to write a > simulation to demonstrate the ideas in his new series of books 'The > Nature > of Order' (the first volume is out, and truly outstanding).

I am far away of Scotland and only a enthusiast beginner, but plenty of good will to do the job. Check http://ar.geocities.com/edgardec2001/Welcome.html for tutorials I write and http://ar.groups.yahoo.com/group/squeakRos/ , Archivos (files) section for my projects . I the guy behind SqueakLight , a bare morphic development what could get you some Morphic final app below 4 mb.

Well, if you really feel you can pick and choose, you might as well choose an argument, not an illustration. > As with many of the arguments you are making in this thread this is wildly > over the top. A more reasonable comparison ... No comparison is a replacement for an argument. That A did it doesn't mean it is reasonable when B does it. The question is should the behavior of Streams be symmetric for reading and writing, or "robust" and on that you've made no arguments, and replied to none of mine. But addressing your comparison while I'm at it, you may note that while ImageReaderWriter is explicitly smart about detecting formats, it can not (AFAICT, not very familiar with that code) directly be used to write forms to files - to do that, the application needs to choose a subclass corresponding to a format. The application needs to make that decision, the stream shouldn't. It is ok, however, for JPEGReadWriter to read and write JPEG formats, without asking the application. However, I would find it most confusing if JPEGReadWriter, on encountering a BMP, didn't bring up an exception. In the same way, specific stream classes can A. Represent a specific encoding, and stick to it for reading and writing, or B. Do detection, but not be usable for writing without specification of encoding. It is an issue of symmetry of expectation between reading and writing. Beyond the effects of the assymetry being very confusing and unexpected (as I argued in my response to Ned), in my eyes, this assymetry is also ugly, though I guess that might be a matter of taste. > > Streams should not try to "detect" line endings. > Why not? That's just what you were saying is great about Emacs. EMACS is an application. Something that is a feature in an application can certainly be a bug in a low level class library. If you're asking "why not", then obviously we are not communicating at all. Again. Daniel

Latest VMMaker package on SM
by Tim Rowledge 01 Aug '03

01 Aug '03

Finally, the hopeful-beta is there. It has the BC, Islands and non-CM-method stuff included to support experimentation. It seems to run ok for me. It is still not possible to generate a non-inlined VM completely. There is a strange problem with Interpreter>fetchByte when using the globalstruct stuff, along with a bunch of problem I found in B2Dplugin and others. tim -- Tim Rowledge, tim(a)sumeru.stanford.edu, http://sumeru.stanford.edu/tim Useful random insult:- Low on thinking gas.

I got the answer at the same time when my posting came in. Ah, right! I forgot that there is code which is not in a package. How inconvenient! ;) Hmm, wouldn't it be easy to convert the existing system categories to Monticello packages. Then you could just reload any of them in case you needed. I have to think about that. Probably I am again forgetting something very basic. It's been a long day. Cheers, Bernhard
